here in thailand, the price differences are not very big and they are transparent, but having to install a separate app for each provider and use different payment methods is not very customer-friendly. there is definitely room for improvement ...

 

i forgot to add: plug and charge would be the simplest and probably the best solution for everyone. tesla has been doing this for years with their own charging network ... 

We almost use EV Station Pluz exclusively, for the 7-11 & food options.  PEA being 2nd choice or MG, if convenient.   Used eVolta last O&A, finally, as now have more DC stations, and we had money on the wallet.   Doubt if we'll use much once wallet is low.

 

If Spark still has the 350 coupon promo going, we'll register for that, as hard to turn down free electrons.  Think Elexa is the only other we have and used.   Altverin (Lotus's) which we haven't used yet, along with EA Anywhere, I think.

Regarding the EVolt app.  Today when opening it the app required an update first....so, I updated it from Google Play.  The update was saying the Evolt app added a "credit card" payment option. 

 

I tried to add my TrueMoney virtual credit card twice.   Both times it failed to add after the successful 2C2P OTP process where 1 baht is debited and then is suppose to be immediately funded.   HOWEVER, at the very end the card add process the Evolt app gave below message acting like the Truemoney virtual credit card was "not a credit card."    I have loaded the True money credit card in various other charging apps and they all accepted the card.   Additionally, the 1 baht debited from my TrueMoney CC acct was not immediately refunded. 

 

I contacted Evolt customer service via LINE about this issue....and I also mentioned the TrueMoney CC has been accepted by all other charging network apps I use.  Evolt responded quickly confirming Evolt does not accept the TrueMoney CC.  And also saying the two 1 baht debits would be refunded in 7 to 14 business day.   

 

Now a person can still add money to the Evolt wallet via QR PromptPay like I've already done.   I haven't tried to add my Thai bank "debit"card to see if a debit card will be accepted because sometimes when a charging app state/implies it wants a credit card it will still accept a debit card.  Will probably try adding my debit card later just out of curiosity, but right now the wife and I need to make a groceries run.

Tried adding my Bkk Bk "debit" card.  A no-go....tried twice.  In fact, it would not even attempt the 2C2P OTP verification process as a message would popup in less than a blink of the eye basically saying Sorry Dude.  Somehow the Evolt payment system is able to determine instantly that's it's a debit card vs a credit card and not even attempt the verification process.  

 

I'm not going to try loading one of foreign credit cards as I can still top-up the Evolt wallet via QR Promptpay....plus I will probably rarely use the Evolt system since I have so many other charging networks to use which have a lot more DC chargers than Evolt.....other charging networks that accept debit cards, TrueMoney CC, QR PromptPay, etc.  

 

I expect that since the TrueMoney virtual CC is basically a "prepaid" CC that pulls money directly from your TrueMoney wallet balance and the wallet balance of the second determines if a payment transaction is approved or not VERSUS it actually be a "line of credit" of X-amount with a credit card company that Evolt considers such a prepaid card (i.e., Truemoney CC) more risky. 

 

Say for example the possibly of Evolt not immediately getting paid for a Bt100 charging session every once in a while because the person's TrueMoney wallet had too low of a balance and the payment rejected due to only having a  Bt99 or less Truemoney wallet balance.  Then Evolt probably locks the person's Evolt account until the person pays which might take some time and effort from Evolt...and waiting for that customer getting around to wanting to pay for the charging session.

Below shows some more charging networks in Thailand.   A couple are major networks like On|ion and MEA but seem to be concentrated in major cities like the greater Bangkok area and seem to concentrate on locations such as malls, condo buildings, businesses, etc.,  "and predominately use AC 7-22KW chargers" although they do have some DC chargers.   

 

When the wife and I went on a road trip the other day to Mueang Chonburi we stopped at the Central Chonburi Mall right in the center of city for lunch at Sizzlers.  Parking was hard to find BUT if I had been registered with the On|ion charging network which had like around 10 charging parking slots with only 2 EVs charging I could have parked in one of those slots and done some slow AC charging while spending an hour or so at Sizzlers.   On|ion chargers seems to be a most Central Malls plus some other non-mall locations. 

 

The My GWM app seems to be very similar to the BYD app which concentrates on giving info about your GWM EV but you can apparently also use it for charging and it appears anyone could register and use it for charging.  Maybe someone uses below "My GWM" app and can provide more detailed crossfeed.  

 

One or two of the apps give little or no info regarding their chargers locations unless you register "or you go to their website to see the locations/types of chargers."

 

In my earlier post I mentioned I'm thinking about registering with two of the smaller networks once they get some more DC charger locations....those two networks are OneCharge and iGreen+ shown below.

 

If anyone is registered with and use below apps for charging please provide us some crossfeed on what you think about them.

 

 

 

 

 

 

In my above post where I said I was thinking about registering with OneCharge and iGreen+, well, I did register with OneCharge today....easy and fast registration.   I finally decided to register since the wife and I were going to do a mother-in-law visit today and OneCharge had two DC chargers kinda close to dear ol' mom's house.  I would drop the wife off at mom's and then go visit both charger locations to kill time until coming back to pickup the wife and head back home to Bangkok.

 

Now the OneCharge app did not have any pictures of these two particular charger locations (most of their locations do have pictures)....when I got to the first one it turned out to be a big-rig truck park & maintenance business....and the 2nd location turned out to be a garbage truck park & maintenance area/business. 

 

When pulling into these business compounds the OneCharge chargers were right after entering...open to the public 24/7 at both locations.   I expect the chargers they had at their businesses were primarily for their own use but they were also open for public use...might as well make some money off the chargers when their own business vehicles are not using the chargers.   But if you didn't use the OneCharge app you would never know these chargers existed...were available to the public.   I did a brief charge at both locations...do some complete real world tests...I didn't experience any issues...both charging sessions went fine.

 

Below are a few pictures of the 180KW charger at both locations and also some snapshots from the OneCharge app focusing on the payment methods.  The charger at both locations happened to be ProCharge charger which I guess is a charging company that is partnering with the OneCharge platform/app at some locations.  When using the OneCharge app you see many different chargers where they are partnering with other charging companies. 

 

You don't need to register on the OneCharge app just to see charging locations/types of chargers but to see any significant info regarding payment you need to register.  However, I explain the payment options below  in more details with some snapshots from the app.  Also the OneCharge website and links to the app on Google Play Store and Apple Store are below.   The app worked just fine....simple to use. 

 

OneCharge is a growing charging network....might have a charger(s) you can use....take a look at their app.....everyone lives in different places and travels to different places so the OneCharge charging network may or may not be of much use to a person....all depends.

I need to make an update to the "minimum" amount allowed to top-up the OneCharge wallet if you decide to fund it....see the last image in my above post for the wallet top-up methods.   As mentioned earlier I did not fund the OneCharge wallet as I just used direct payment via my TrueMoney virtual CC for the brief, low cost charging tests I did....plus, I didn't want to put Bt300 into the wallet if I can always pay via another easy way.  If some day I can't use a credit/debit card for direct payment of each charging session then I will fund the wallet using my Thai bank mobile app and/or PromptPay.   

 

If you top-up using one of the Thai bank or TrueMoney Wallet mobile app methods shown in the last image then the min amount is Bt300; HOWEVER, if you use the PromptPay  method the min amount is Bt50.   So, if you wanted to fund the OneCharge wallet you could start off with as little as Bt50. 

 

When I posted earlier the min amount was Bt300 that was after I clicked the BBL Mobile Banking method which popped up with a min Bt300 required and just assumed for all top-up methods the min allowed would be Bt300.  But tonight when playing with the OneCharge app I clicked the PromptPay method and it allows as little as Bt50.  So, I went back and clicked all the Thai bank and TrueMoney Wallet options and for each one reflected a min amount allowed of Bt300...but when clicking PromptPay it allows down to Bt50.

which charging stations support "plug and charge" in thailand as of today?

to my knowledge, byd rever and tesla (for tesla vehicles) do, are there any other charging stations?

 

thanks, motdaeng

Yes....some networks do like PEA, OneCharge, ReverSharger, and others.  The process will use the vehicle's VIN number or charging system MAC address.  But even when the charging network may support autocharge if the vehicle don't then it's a no-go.

 

In some of my above posts where I said I was thinking about registering with OneCharge and iGreen+, well, as I posted the other day I did register with OneCharge and did some real word test charges as I reported. 

 

And today I registered with iGreen+ and did one real world charging test...all went fine.   iGreen has around 230 charging locations around Thailand with the great majority being at businesses, condos, restaurants,  resorts, hotels, etc....but 21 of the locations also have 120KW DC Chargers.   It's another one of these growing charging networks that's not very well known yet. 

 

iGreen offers wallet and direct payment via card methods.   You can fund the wallet via PromptPay or LINE Pay and can fund it with as little as Bt50.  When trying to add a card for direct payment it would not accept my TrueMoney virtual Mastercard credit card or my Thai bank Mastercard "debit" card....it would return an error message of "can not bind this type of card."   My evaluation is iGreen only accepts regular credit cards and does not accept pre-paid credit cards like the TrueMoney CC...nor do they accept debit cards.  YMMV.

 

A nearby mail I visit at least once a week here in western Bangkok had two 120KW iGreen DC chargers on different ends of the mall parking each with two connectors.....and also two 22KW AC 7-22KW chargers.  The chargers are located in "prime" parking areas.  So, when the wife and visited Foodland today for some lunch and groceries I did a test using one of their low power 7-22KW AC chargers vs their DC fast chargers.   I really just wanted to do a low cost, "slow" charge test when shopping for an hour or so.   

 

The charging test went fine....startup of the charging was almost immediate....none of this 30 to 60 seconds startup common when using a DC fast charger....and the stopping/paying of the charging session was very fast also.    The app worked just fine.

 

So, now not only do I have one more charging network I can use and also have access to some prime parking at this mall where every once in a while it's impossible to find a parking space....like on Tuesday's and Thursday's when the mall sponsors exercise dancing for seniors and I think half of the old ladies in Bangkok show-up for dancing the years away.  And no, I'm no go there for dancing....just getting groceries at Foodland. 😀

 

Below are payment screen related to topping up the app's wallet (min amount Bt50)....and as mentioned there is also a direct payment card method but I could not get my TrueMoney virtual MC credit card or Thai bank MC debit card accepted....I did not try any of my foreign credit cards.    Using the wallet method is good enough for me especially with a min Bt50 requirement and allowing top-up via PromptPay/QR code.

 

See snapshots and links below for more info.   And tomorrow I attend my first session of "Chargers Anonymous" in trying to kick my charging app registration habit.   😁😀

What ... you don't believe me.   How Dare You 

 

How can the car be done charging at the CS before you're done doing all your 'business' there,

 

Well, let me tell how that all works out.

... pull into station, plug in, maybe 5 mins time, vs up to 10 mins, if getting petrol

... take dog for walk, can easily take 10 mins, see below ***

... wife hopefully P'ing while I walk dog

... time for me to P, 5 mins, if only P'ing

... off for a munch, scan option, wait to be prepped, easily 10-15 mins

... eat the food, at least  10 mins.

... 10+5+10+10=35 mins, on the short side

... doesn't include verifying any hotel options, as we rarely book in advance, since always on the fly.

 

So yes, the car is always done before we are.  Usually at 90-95%, if not 100%, and good for another 3+ hours on the road, if needed ... Hell No 

 

***Took the dog last night, for a very quick dump, and didn't even make it to the end of the soi.  Usually takes longer.  That alone took 8+ mins, and nothing new to sniff or mark vs when at PTT, have to sniff & mark everything.   Dog owners can relate 

 

 

 

 

 

I'm here all week ... Don't forget to tip your server  😎

Well, let me tell a long-winded story about the most important charging station in Thailand  (or at least to me it is)...and that charging station is Pib's home 7KW wall charger.  😀

 

Been wanting to provide this “EV Wall Charger” cross feed for a couple of months now.  It’s long-winded but fully describes the home charging problem I had. 

 

My EV 7KW wall charger is made by Zhida and was provided free by BYD along with free installation when buying my new Atto in Oct 2023.   The charger generally worked fine during the first year but “on occasions” (i.e., intermittently)  it acted strange by dropping the charge rate from its full charge rate of 30 amps down to 16 amps.  This resulted in a kilowatt charge rate of 6.2Kw or 3.1Kw as shown on the car's display.   And it wouldn’t recover to 30A unless I stopped the charging, unplugging the charging gun from the EV, plugging the charging gun back end, and then restarting the charging.   As mentioned this was an ‘intermittent” problem…didn’t happen often….maybe once a month. 

 

Come Aug 2024 BYD offered “free or reduced rate” charging promotion on the ReverSharger charging network for 5 months.  I was in the category of getting “free charging” and used the promotion extensively (free charging is good) until the promotion ended the first few days of Jan 2025.  I had easy access to plenty of ReverSharger DC chargers since I live in the Bangkok area.   During this Aug 2024 to early Jan 2025 period I only used my Zhida 7KW wall charger 10 or so times for a few minutes each time to give the charger a little exercise for a few minutes “and just to make sure it still worked.”   No problems experienced during those brief wall charger charging sessions.

 

Now come Jan 2025 when the BYD free charging promotion ended I was back to using my Zhida 7KW charger full time again.  And this is when that intermittent problem of the charge rate dropping from 30A to 16A (6.2Kw to 3.1Kw on the car display) became more frequent….like on every third charge or so…but sometimes it might go a half dozen times with no problem.  Other times it was like every time….but on the average it was about every third use.   

 

"The problem would almost always occur within the first 5 to 25 minutes of charging."  But stop the charging (now at only 16A), unplug and replug the charging gun, and restart the charging and it would usually continue to charge at the full 30A rate even up to 10 hours like if I was charging from close to 0% SOC to 100%.  But sometimes it would drop from 30A to 16A again when I would repeat the stop & start again charging process.  This problem was becoming a pain especially since I needed to pay attention to the charging during the first hour to ensure the charge rate had not dropped because charging at 16A is a lot slower than at 30A....it doubles the required charging time.

 

Having an electronics repair background from my much younger work days, almost always wanting to attempt repair things vs just buying a new one and being a DIYer, I went into troubleshooting mode in trying to find the “core cause” of the charging problem….that is, was it something I could find and fix cheaply or was it beyond my repair capabilities, was it the wall charger, or maybe it was the EV onboard charger.

 

Many, many times I checked, wiggled, twisted, etc.,” the charging cable….even did an end-to-end cable continuity test using my ohmmeter.  Wiggle the charging gun while it's plugged into the EV to check for a loose connection…..use an ohmmeter to check the PP (Proximity Pilot) pin 220 ohm resistor in the charging gun (that resistor is connected between the PP and PE pins) as that resistance between the PP and PE pins tells he EV onboard charger when the charging gun is connected "and" the max amperage the charging cable can handle.  The charging gun pins were still in great, like new condition.  And a visual inspection of charging connector pins on the EV itself showed no problems like a pin(s) being damaged. 

 

During this visual inspection of the "EV connector on the car" that’s when I saw the "Control Pilot (CP)" pin was shorter than all the other pins.  The CP pin is on the upper right hand corner of the EV's connector.  The CP pin/wire carries the communications back and forth between the EV and external charger such as to decrease or increase charging rate and monitor/commuicate other aspects of the charging process.   I thought that just may be the problem….the EV car connector CP pin was broken or got pushed back into its connector creating a funky, intermittent connection.  

 

But no, upon further research (i.e,. googling)  the CP pin is shorter on purpose/for a reason….a safety reason....it’s to ensure it is the last pin to make a connection to ensure the high amperage pins carrying the AC voltage and also the Proximity Pilot (PP)  pin are fully connected.  And I visited my nearby BYD dealership to look at showroom vehicles EV connectors....and sure enough the CP pin was shorter in those brand new vehicles….not unique to BYD vehicles….it's just how EV charging connectors are made per EV standards/regulations.    If you didn't know this then go take a look at your EV car charging port....look at the CP pin in the upper right hand corner of the car charging connector (on the car, not the charging cable) and you will see it's not as long as the other pins....you may need to use a flash light to clearly see how it's shorter than the other EV car connector pins.

 

I also checked the wall charger circuit breaker in the house main circuit panel, the RCBO breaker next to the charger, all wiring connections, grounding, etc….everything always checked-out fine.  And once again I did cable, charging gun, PP resistor checks “many” times over several months…every check never revealed anything amiss.   "Intermittent" problems often hide when you are trying to find the core cause....it's like they know you are looking for them and they go hide for a while (i.e., start working perfectly again).   

 

Then I started looking to see if I could see some other obvious problem “within the Zhida charger” by disassembling it…removing its front cover….like maybe finding a loose or corroded connection, a cold solder joint, some component showing signs of overheating, etc.  I also did a bunch of other tests where I tried to control the “cooling” of the Zhida charger to see if maybe the problem only occurred when the charger “got so warm/hot.”   I even ran these tests with the charger’s front cover removed exposing the circuit board for maximum cooling effect.  I also completely disassembled the charger so I could visually inspect both sides of the charger’s main circuit board.   None of these tests and visual inspections were able to help narrow down the problem.

 

Then I started thinking maybe the problem is with the EV….that is, the EV onboard charger/BMS system.   But first I wanted to do some more testing using “other 7KW AC chargers.”    So, I went and used some 7KW chargers at commercial charging stations like on the ReverSharger and PTT charging networks.  Did at least a half dozen such AC 7KW charging sessions over approximately two weeks and never experienced the problem.   With none of those commercial 7KW chargers ever showing the problem it would seem logical the EV onboard charger is OK and the problem was with my Zhida charger.  

 

“However,” I’m was still wondering if maybe it could be my Atto’s onboard charger/BMS. However, monitoring OBD2 data over several months never revealed any potential issue like the onboard charger or battery overheating.   So I took my Atto to my BYD dealership where they checked the EV charging system with their diagnostic equipment and also their in-house 7KW charger….they couldn’t find any problem with the EV charging system.  This dealership service center check was free.    And the problem reappeared the day after the service center check.

 

I’ve now resigned myself that my Zhida wall charger is the problem and it’s an "internal" wall charger problem and not some external or visible problem such as the charging cable that I had already checked many times over several months.

 

I even contacted both Rever Automotive (HQ BYD for Thailand) and the Zhida Service Center in Bangkok via their LINE official accounts as I wanted to see if I could get my Zhida charger checked, repaired, get a new charger, etc.  But both told me that the charger itself is only guaranteed for 1 year although the installation is covered for 2 years.  By ”the installation” I mean all the wires, breakers, conduit, etc., that was used to install the charger at my residence but not the charger itself.  I kinda expected this response from both as I knew the “installation” was covered for 2 years per the installer’s paperwork, but probably not the charger as the installer was just installing the charger BYD provided to me when I picked up the car and I then provided to the installer the day they came to install everything. 

 

Now I could have called the wall charger installer to come take a look but I didn’t as I just knew the problem was not with the installation based on checks I had already done.  Zhida was more than willing to send a service rep to look at the charger but just to make the visit there would be a Bt1,500 fee….and any required repair parts would cost extra.  A replacement 5 meter 32A charging cable with charging gun would be Bt3,745 and a replacement main circuit board for the charger would be Bt4,500.  The cable and circuit board would carry a 1 year guarantee if Zhida techs installed them.  But if I bought them from Zhida and installed them myself the price would be the same but no guarantee.  

 

The local Zhida service center in Bangkok was very responsive to my questions and responded in good English….ditto for BYD Rever Automotive customer support.   And the Zhida service center did say during our online messaging that from the description of the problem I had given that their technician said the problem “could” be with the charging cable assembly.    But since I had already checked the cable assembly many times and with those Zhida service/repair prices I figured I would be better off just buying a new charger off Lazada/Shopee which also comes with a new cable & charging gun versus having the Zhida charger repaired. 

 

“THEN, I literally stumbled upon the core problem” one evening when charging by lightly stepping on the charging cable I noticed the charger’s external ammeter I had installed  became erratic….dropping way below 30A…even down to 16A.  I then began wiggling, handling the cable over its entire length and the ammeter reading was very erratic…jumping between 16A to 30A.  It was now  looking like a cable problem.    I wiggled, hand twisted the cable all the way from the wall charger to the charging gun and “it appeared there was a bad/loose connection within the charging gun”…not within the cable but after the cable entered the charging gun.     

 

Now I had stepped on the cable a few times before and also done “cable and charging gun” wiggling many, many times in trying to find the problem which always ended with negative results.  But this time my “wiggling” was consistently indicating the problem was inside the charging gun….probably ”not” at the EV connector  because of the way I was firmly holding the cable connector but “within” the charging gun."  I pulled out my ohmmeter again to check the Proximity Pilot 220 ohm resistor and it was fine….measuring around 219.5 ohms which is well within allowed tolerance where the tolerance suggested by charging equipment standards/regulations is from 150 to 330 ohms to indicate a charging cable able to carry up to 32A is attached.

 

As I wiggled & wiggled the cable where it entered the charging gun the problem suddenly went away (i.e., problem goes back into hiding)…..and I could not get the problem to reappear over the next week during numerous, frequent, & brief charging sessions.   I looked at the EV connector pins and charging gun connector again….they looked great…shiny, clean, no damage….looked like new.  I decided I would try opening up the charging gun to look for a problem like a loose or corroded connection. But getting inside the charging gun was HARD, VERY HARD  to do based on its design.  A design that was geared towards “non-repair”….was not designed to be easily opened-up and internal connections/resistor repaired or  replaced.  Instead, the design seemed to be geared to require replacement of the entire charging gun.    That is, cut off the cable right were it entered the charging gun handle and attach a new charging gun which also comes with a new PP-PE resistor.

 

I ordered a quality Feyree charging gun off Shopee (total cost Bt781 with discount/coupon/free shipping).   Many different charging guns sold online….some better than others….the particular Feyree charging gun I ordered looked to be a quality design.  Once getting that replacement charging gun I decided I would now “get serious” in trying to open-up the original/defective charging gun without inflicting serious damage because I really wanted to see inside the charging gun and possibly get lucky in being able to repair some minor problem like a loose connection, etc.  Plus I didn’t want to give-up approximately 25-30cm of the current cable length since I needed all 5 meters of the cable to easily reach my EV for charging.  I wanted to cut the cable right were the wires are crimped into the pins which would result in only around 2cm cable loss/shortening.     And if I seriously damaged the charging gun while trying to open it then no big deal as I have a new, replacement ready to install. 

 

Well, I was able to get the original charging gun opened-up with minimal damage (but it wasn’t easy) to where I could clearly see the wires, connections, pins, and resistor in the charging gun.   Didn’t see any problem…no loose connections…no corrosion….and the resistor measured 220 ohms just as it’s suppose to. 

 

So, I decided to change the charging gun as I had the necessary tools to do so which included a large crimper which could easily crimp 6mm2 wire & steel alloy pins used in the charging gun.   After installing the new charging gun which has now been approximately three and a half months ago I have not experienced the problem even once….just a steady 30A charging rate no matter how long I charge.     And believe me I have done “many” charges in trying to make the problem reappear but thankfully the problem is gone…now fixed.   

 

So, what was the core problem besides “just some undetermined charging gun problem?”   Well, I determined the problem to be the 220 ohm resistor between the PP and PE pins.  A resistor that costs just a few baht.   Not a problem with its ohmic value, but a resistor “manufacturing defect.”  That defect was a “cold solder joint” on one end of the resistor….specifically where the resistor’s short terminal lead is soldered to the resistor’s metal cap….a “tiny” cap that is press-fitted on the resistive element during manufacture.   This cold solder joint was "intermittently" causing a bad connection depending on how warm/hot the charging gun got during the charging process and/or if there was any charging cable movement transmitted into the charging gun causing the resistor to move ever so slightly.

 

“I came  to this cold solder joint conclusion” as I was very gently removing some heat shrink tubing from the resistor as I wanted to see the resistor and also to check the resistor’s end cap connections because a few times over my decades of repairing electronics I came across a couple of resistors with this problem in electronic equipment….it’s rare but happens.    Just as I almost had all heat shrink tubing removed from one end of the resistor the terminal lead on the resistor “literally just fell off” like the heat shrink tubing had been the only thing keeping the resistor’s terminal lead connected to the resistor’s end cap/main body….kinda like just touching instead of being soldered.   

 

But when removing the heat shrink material from the other end of the resistor that terminal lead & cap were in fine condition with a good soldered/welded connection.  And in the case when car was being charged and the charging gun heated-up (along with the resistor) the resistor’s “connection” would expanded & contracted “ever so slightly” resulting in an erratic and intermittent connection.  Ohmic value briefly changed most likely to a much higher value (something above 330 ohms) due to the faulty connection which would have signaled the EV’s onboard charger that the wall charger cable cannot support 30A but only 16A or less causing the charging amperage to drop from 30A to 16A.   In a 32A rated cable the PP-PE resistor will be a 220 ohm resistor…..in a 20/16A cable the resistor will be a 680 ohm resistor.

 

Long story short is a little over 3 months ago I replaced the Zhida charger’s original charging gun with a new charging gun (including the PP to PE resistor) and the problem has not reappeared  .I’ve used the charger dozens and dozens and dozens of times and I now just get a steady 30A charge rate no matter how long I charge, whether I step-on or wriggle the charging cable, no matter how hot or humid the weather is, etc.    Yeap….a resistor cold solder joint which occurred at the factory is how I figure it….was the cause of this very frustrating and hard to pin down intermittent problem.

 

See below for some pics of the old/original charging gun after I disassembled it WHICH WAS HARD TO DO without inflicting major damage based on how it was put together at the factory.  I even had to use a hand grinder to cut off a stainless steel clamp within the charging gun) to include some pictures of the small 220 ohm resistor that I’m 99.9999% was the problem.  Also some pics of inside the wall charger itself are included as I even completely disassembled the charger during my troubleshooting looking for a problem.  I’ve added a few comments to the pics for more info.

For you Spark EV charging network users....get some free charging 23-31 Oct when charging "at least Bt100 per charging session."   Bt99 or less won't hack it to get a coupon.   Spark EV is celebrating now having 100 charger locations....and in their app it does show exactly 100 stations now....all DC chargers.      

 

Spend at least Bt100 per charging session and get a Bt100 reimbursement coupon approx a few days later....reimbursement coupons sent out on sent on 27 Oct, 30 Oct, and 3 Nov.   The coupons will have an expiration date...not sure how long....but I expect it will probably be 30 or 60 days.

 

Charge for Bt300, get a Bt300 coupon....charge for Bt100, get a Bt100 coupon, charge for Bt500, get a Bt500 coupon., etc...etc.  Rinse and repeat as many times as you want between 23-31 Oct.   That's the way I understand the promotion.

 

For me with my BYD Atto with 60.5KWH battery and considering Spark EV charges Bt7.9/KWH that means I will need to charge around 20% to reach Bt100.  I should be able to take advantage of this several times over the promotion period based on some planned travel. 

 

 Below are some Spark EV google translated details from the Spark app and their Facebook/LINE page.

 

 

 

 

 

 

 

 

 

Today I topped-up twice using Spark EV while on an approx 200km trip.....Bt352 worth of electrons.   Did not need to top-up just for a 200km trip but hey, since the electrons will end up being free then why not.   Hopefully in a couple of days Bt352 will be credited back to my Spark wallet. 

 

And if the creek don't rise tomorrow/Friday the wife and I will do a Bangkok-Pattaya roundtrip where I plan to top-up at  a Spark charger in Pattaya and top-up again once arriving back in Bangkok.   

 

If I use up all of the Spark EV free electrons before any of you other Spark users get a chance to get some I apologize (not).   😃

Interesting , I took it as the coupons are in 100 baht increments ?, maybe just me misinterpreting the promotion ?

 

I still have the majority of my initial 300 baht left and the 50 baht coupon which I doubt will be included in the promotion ??

Using this premise my intention was to charge up to 50 baht, to clear the coupon, then charge another 100 baht …… yep, am probably overthinking this !!

 

Tbh, this coming week is very quiet and probably won’t be able to take full advantage, have a couple of ongoing diy projects and no plans to visit the mil’s ( my regular 420/450 km round trip ).

 

Although the girl is home from uni and the boy has tomorrow as a holiday from college (in lieu of today ) so have already mapped out a little trip to one of our favourite touristy spots for some lunch which is around 30 km’s drive up the Super Asian Highway and a Spark charger at a Bangchak pump is 5 km’s before that. So an opportunity to check out the promotion could well be on the cards ! ….. watch this space !

It may indeed turn out to be that way....which means a person would want to stop charging as soon as they hit a 100 increment....i.e., stop once barely going over 100 vs 106 if you figure you can't make it to 200......stop at 200 vs 215 if a person figures they can make it to 300, etc.

 

 

 

 

@Andrew Dwyer

   Here's one for you....this morning I planned to stop a Spark EV charge session "at a hair over" Bt200 to ensure I barely reach Bt200.  Once I was within a few baht of reaching Bt200 as I was opening my phone case lid the charging stopped...stopped at a few stang overBt199....less than a baht short of Bt200.   I don't know if the phone lid pressing on the screen caused the problem or I accidentally touched the stop charging icon while opening the phone case lid. 

 

   And even though a message pops in the Spark EV app when stopping charging asking if you are done charging it's not really a question where you can press something basically telling the app that  "No, I'm not done...I pressed something accidently, don't stop this charging session...please continue on."   

 

   That charging session is actually done....you see the charger itself has stopped charging...the car shows its stopped charging....money deducted from your Spark wallet....do you want a receipt....thank you for your business...have a nice day.  

 

   So, if it does turn out any amount "between" 100 baht increments is not reimbursed (like Bt99 of my my Bt199 charging session) and it probably will, well, I just ended up paying Bt99 that I will not get reimbursed for.....I'll only get Bt100 for that Bt199 charge session.

 

   This little episode has now made me a big supporter of the stop charging icon type where the "sliding type" icon is used....that is, where you have to slide the icon button from left to right to stop the charging because that prevents an inadvertent/accidental simple touch of the screen-stop charging button.   Or if a press to stop icon is used it asks you to confirm and press again to really stop the charging.

 

  Oh well, I hope financially I'll be able to ride out this probable unexpected Bt99 financial hit.....a Bt7.9 per KWH Spark electrons hit that I could have got at Bt5 per KWH on my home wall charger.😃

Yeah, while an additional step is often deemed unnecessary it is preferable to accidentally stopping a charge or accidentally sending an email or accidentally posting a comment on here before finished etc etc.

 

I haven’t taken advantage of the Spark promotion yet as unbeknown to me ( I am always the last to know ) the girl had some online lessons yesterday so we postponed our trip out until today.

 

I know i won’t take full advantage of this promotion as am busy and certainly don’t do as much O & A ing ( to quote a mutual acquaintance) as yourself, didn’t leave the house yesterday !.

A rough estimate of my current battery status (66%) tells me that i am a little short of being able to charge 250 baht ( my theory being the 50 baht coupon will be used first and not count in the promotion ) so maybe only get 100 baht for free.

 

An alternative is that we will take the girl back to her Uni tomorrow and there is a Spark charger the other side of the highway ( within 5 kms) to her Uni but Sunday traffic heading south towards Bangkok is usually a bit of a nightmare and tomorrow is the last day of a 4 day weekend so might be disastrous !!

 

Another alternative is me and the little lady take a leisurely lunch, as in my first option, without the kids, sometime next week when my battery is down to a low level and gain a few coupons we can use in the future on our frequent trips near the Nakhon Sawan Spark charger.

 

Tbh, am not as enthusiastic about this promotion as the 5 months BYD free charging promo as it involves a little bit of extra work.

Plus my TOU meter means I can get around 500 km range for around 220 baht so why should i be bothered ?

 

But, having said that, as a Yorkshireman born and bred value for money is top of my list and I will no doubt make the effort to get something for free 😀

 

That reminds me, hope you are checking in daily on the TrueMoney app @Pib !!

Yea...a lot of these free charging promotions are not always easy or effort free to take advantage of unless maybe you happen to live close by or pass by some of the chargers in your normal travelling....and there are enough of the chargers to avoid the desired charger always being in use.  

 

For that BYD/ReverSharger 5 month free charging promotion and the ongoing 1 week Spark free charging promotion I have been lucky in having plenty of the chargers in my normal traveling which is primarily in the greater Bangkok area with "plenty" of chargers....I don't have to go out of my way.   

 

And the wife and I did do a Bangkok-Laem Chaban Sea Port & Pattaya round trip yesterday and topped-up at a Spark charging station in Pattaya (three 180KW chargers comprised of 6 charging connectors)...it was at a Bangchak fuel station.  Drove  around the Laem Chaban seaport area and then on to Pattaya.  At Pattaya we drove the entire length of Beach Road right on the beach and even drove the entire length of Walking Street since it's open to vehicle traffic during the day.  It had been too many years since I drove around Pattaya a little. 

 

I just wish the  Expressway/Motorway system had been free because I paid Bt400 in roundtrip tolls starting from my western Bangkok home...but hey, I didn't have to fight non-toll road traffic. 😁

 

Traffic was pretty heavy on the expressways going to Pattaya when we went,,,,only a few times was I able to go at 120KmH except maybe for 20 kilometers total..  Now coming back to Bangkok was better where we could move along at 110KmH for at least 50 kilometers of the trip.  But cruising along at the 120KmH speed limit for most of the expressway driving was simply a no-go...too much traffic. 

 

And on the way back to Bangkok around 2pm there was a #7 expressway accident on the "going to Pattaya side" that backed up traffic around 15 kilometers.   I feel sorry for anyone who got caught in that traffic jam.....the wife and I agreed that it was the longest traffic jam either of us had ever seen in our lives as we zipped along in the Bangkok direction at 110KmH.    If we had got stuck in that traffic jam by leaving for Pattaya later in the day it would have turned a good trip into a bad trip.

Why?  Does TrueMoney have some kind of promotion going on?   But the answer is, No, I haven't been checking in daily.

I haven’t quite figured it out yet but checking in gets some cash back, seemingly 3.5 baht every 10 days although I think it depends on how much or how you spend the TrueMoney .

Yeah, I wish I had a road trip planned this coming week.

 

Anyway, went with option 1, 25 km’s up the highway to a Spark charger then on to a bit of lunch, now relaxing.

 

The charging didn’t go quite as planned.

I had thought I would charge 50 baht, stop charging to clear out my previous coupon but two cars pulled in after me ( an Atto was already occupying the other charging cable ) so i felt compelled to continue on.

I still wasn’t sure if the 50 baht coupon would be used automatically and couldn’t find out until I had stopped charging it appeared.

Although the status of charge appears in baht, as well as time and kWh, my baht balance in the wallet didn’t reduce.

My girl had already confirmed that the coupon was to be in 100 baht increments so i figured I would go to 150 baht spent.

At the last minute i figured that i could go to 200 baht ( not enough battery space to get to 250 baht ) and choose to pay 200 baht from my wallet.

 

In hindsight i don’t know why i chose this option as it was my worst !

So i stopped at 207 baht, 50 baht came automatically from my coupon, in effect paid 157 baht to receive a 100 baht coupon.

 

 

But, at least I know the score now and if i get chance will do it right next time !!

 

I did find the charging app slightly annoying as it reset every 8 baht or so and as expected I was stuck on 199.25 baht before jumping to 207 baht.

Could have been my phone signal as last time it seemed to update more regularly.

 

Anyway can’t complain , lost 57 baht but gained 100 baht so in traditional Yorkshire style “ am reet wi that “

Yea, the Spark wallet is really sub-divided into real money you use to top-up the wallet and another portion of credit earned from coupon redemptions. 

 

So, say a person has Bt200 in the real money portion in the wallet and also Bt50 in the coupon credit portion of the wallet. then when paying for a charging session the amount in the coupon portion is "automatically first used.'   And if not having enough coupon credit to pay for the total charging session bill the coupon portion is still automatically used first and then the real money portion of the wallet is then tapped to pay the remaining portion of the bill.  It just appears as one payment,  but both portions of your Spark wallet were tapped to pay the bill. 

 

Example: say you have Bt200 of real money in the wallet "and" also Bt50 in coupon credit....this gives a person enough wallet money to pay for Bt250 in charging.   If you charge say for Bt100 the Bt50 of coupon credit and Bt50 of real money is used to pay the bill (all done automatically) leaving a zero balance in coupon credit and Bt150 of real money in the wallet.

 

Then if that Bt100 charging session was during the free week of charging here in a couple of days a Bt100 coupon credit is suppose to show-up in your Spark wallet.  I don't know if it will just automatically plus-up your coupon wallet portion or it will be a coupon requiring the person to take a few quick steps to redeem the coupon that then puts the money in your coupon wallet.....time will tell.  But I'm going to guess it will just automatically plus up the coupon credit wallet portion just like how that Bt50 questionnaire coupon credit worked out a month or so ago.

Yeah, I sort of knew the coupon would automatically be used first then start to use the money in wallet, but for some inexplicable reason i doubted that and thought i might have had an option on how to spend the coupon/wallet at the end ?

I should have stopped at 150 baht or 250 baht, 200 baht was the only wrong option 😀

But who knows, maybe the 50 baht free coupon will be included in the promotion and i will get 2 x 100 coupons 😀…… yup, i should probably stop now !!

Since you charged for Bt207, then regardless of using a previous coupon credit to partially or fully pay the Bt207 this means you should get Bt200 in coupon credit in a few days.

 

On my 1st use a few days ago under this current promotion I had less than Bt2 in wallet coupon credits remaining from earlier promotions so I didn't lose that much in terms of expending a previous free credit just to get another free credit.   

 

The fine print on these various coupons and how the Spark wallet works can give a person a headache when trying to squeeze the wallet for every free electrons possible.

Yup, on Monday i should receive a 100 or 200 coupon  !!

 

I didn’t catch the whole receipt on my photo above and while the total was 207.77 baht, which should result in 200 baht in coupons, further down it does say that a 50 baht coupon was used, so the jury is still out imho.

 

 

But I will consider myself lucky if the 50 baht coupon, which was free, is counted towards another free offer !!

 

One thing is for certain if I do succeed in getting paid twice for the same coupon then i know which 2 numbers i will be choosing for the end of month lottery !!
