Finally is it crazy to buy an EV if charging at home is not possible? Anyone do it?

As stated a few times, depends how much driving one does daily, if using granny charger.  If charging overnight, 10 ish hours, that about half one's battery capacity, for us, MG ZS, so at least 150 kms a day.

 

If plan things properly or simply patient, the 30-45 mins at CS and you're topped up again.  Location dependent on how convenient that is, and can do while shopping, munching, or just having a coffee & Danish.

 

We live kind of rural, but there 3 or 4 CS nearby, within 5 kms.

It's not crazy if you have easy and quick access to a charger and willing to expend time setting at a charger.  But charging at home makes charging a LOT easier and cheaper...about as easy as keeping your smartphone charged.

 

But let's see a picture of your electric meter along with the wires running to and from the meter.

I have a lady friend 76 years old who has MG4 X-Power and she only charges at PTT/Amazon about once a week.  She enjoys a coffee whilst she charges and reads the news.

 

Whilst it costs double charging at home, it's still half the cost of petrol/diesel.

I wouldn't have bought an EV (an Atto) if home charging wasn't possible. It's certainly possible to make it work without but, as PIB says, it's not very convenient. I live in Bangkok.

 

I couldn't be bothered to wait for BYD to install the free charger so I paid for someone to come and do it. Cost THB 3500 + another THB 2500 for the 40A Type B breaker that you need. This was included in the BYD free stuff but they didn't have them in stock at that time (Jan 2023).

 

The guys who did my install did a good job (a firm called Wallbox wallbox.in.th). They simply spliced a separate line and circuit breaker from the main supply into the house - running another circuit off the existing house breaker board or the main breaker would have been a pain, given where they are located relative to where I wanted charger.

 

Here are some pics - the meter we all want to see is the one on the pole usually outside your house. In a mooban I'd still think it would be outside your house.

I also live in a rented house. My landlord is very easy going - I just told him I wanted to install a charger and he said fine.

 

Since it was free I'll likely just leave it if/when I move.

Thanks this is very helpful. I’ll try when I get home or tomorrow to find it.

 

they only needed the main breaker in my house, they saw the 60A and said a second circuit would be needed.

 

these are the byd charger sales people - they have quoted 42k all in

42K is way too much. 

 

If you're doing less than 100km / day use the supplied granny charger

If you're doing 100-200km/day go with the plug in 16amp/3.6kw charger at 6,800 baht or less

If you're doing 200km+ in a day followed by long journey next day budget 12-20,000 baht and get an electrician to fit a 40a breaker in your existing panel and a 32 amp socket in your parking area and buy a 7Kw portable floor/wall box I showed the picture of.

 

There is no way on this earth I would spend 42,000 baht on a wall box.

[Andrew Dwyer]

Regarding the 2nd circuit. ( if TOU meters are still being fitted as a 2nd circuit, if not as reported back in July then forget the following information )

 

I live in a moobahn and the existing meter ( 15/45 I think from memory ) wouldn’t accept an EV wall charger addition so a 2nd circuit with a TOU meter was required.

First step to visit PEA who audited and approved the new TOU meter at a cost of 4,800 baht, they required the car information ( just an online brochure showing charging speed was adequate ) and the Wall charger information ( free ABB charger from BYD , dealer sent an information sheet ), plus receipt for car booking.

 

Wall charger fit by BYD, despite being a “ free installation “ as a second circuit a standard charge of 9k baht was charged ( plus 300 baht for additional cable ). Operation check from original circuit undertaken.

 

Inform PEA and they come to audit charger installation and fit TOU meter and connect to wall charger.

 

So roughly 14k ( TOU meter and BYD 7 kw wall charger ), i roughly estimated with cheaper tariff would ROI at 9k km driven.

 

42k seems very high, presumably including the price of Wall charger ?

 

NOTE: The 2nd circuit TOU meter is only to be used for charging the EV and no additional sockets allowed.

 

NOTE: Due to reports that new 2nd circuit TOU meters are now not being authorised you should check this primarily with PEA before proceeding.

Incidentally I paid 2,500 baht labour plus a few hundred baht for parts to the electrician to install a 32 amp socket at our landlord's home.  The socket was only a cable run of about 2M from the breaker panel and these plug in chargers charge at the same speed as a wall box.

 

Do they ?

I maybe getting my wires crossed (sorry - bad pun) - but, I thought......

 

Plug in Charger / Granny Charger (Standard 3-Pin Plug)

Charges at 2-3 kW

Takes about 24+ hours to fully charge an EV battery.

 

Type 2 Wall mounted Home Charger

Charges at: AC 7.4 kW (single-phase) or 22 kW (three-phase), depending on the setup.

Takes about 6-8 hours to fully charge an LFP battery.

[richard_smith237]

Note: Our 'power' is rated at 15/45 A

 

This was deemed sufficient for the dedicated Type 2 wall charger (Juice box) to be installed, wired directly from our 'in house' mains circuit breaker. 

 

The electric meter itself is actually down the road at the front of the moo-baan (somewhere - I've never seen it) and all the wiring to each house is run underground.

You can get chargers that look like a granny charger but are fitted with a 32 amp industrial single phase plug, they charge at exactly the same speed as the fastest single phase wall box (7.4Kw at 230v).  All that's then needed is for an electrician to fit a 40amp breaker in the OP's consumer circuit breaker panel and cable it to a 32 amp socket where he parks his car.

 

For the OP who rents and may at some point move houses, it's a better option for him because he can take it with him (you can put a screw in the wall and hook it on the wall and it's then a portable wall box).  It's also much cheaper.

@Pib sorry, slightly off topic.

 

have you done a rough comparison for your own setup (atto 3 / battery type / wall charger, etc.) to see how the charging losses

in percentages compare between your granny charger and your wall box? 

 

if you don't have solar, the charging losses (which are always present when charging an ev) could really add up ...

 

thanks, motdaeng.

Yes I have. 

 

My 7KW wall charger and Atto have a 91.5% charging efficiency (a.k.a., charging losses).   The wall charger allows 30 to 31 amps to pass thru it.  I calculated the charging efficiency by dviding the charger's output power (I have a power meter on it's output) into the charging power displayed on the Atto screen (and actually I've used OBD2 data which gives a little better accuracy).  Depending on the traction battery's temperate I've checked the charging efficiency MANY times over many months and the charging efficiency has ranged from 90 to 93% so that's  where I get my average 91.5% efficiency.  So, 8.5% of the electrons are losses due to the EVs built in on-board charger, cable losses, etc...etc....the great bulk of that loss is the EV's on-board charger's conversion of AC to DC volts.

 

And for the BYD portable charger (a.k.a., granny charger....granny safety switch) the charging efficiency is approx 83%....typical for small portable chargers since the EV's onboard charger power usage now accounts for a larger portion of the overall power.  The car's on-board charger AC to DC conversion process is where the great bulk of the charging loss occurs...same for all EVs.    The BYD portable 10A charger outputs appox 2KW....today I did another quick check and the portable charger was outputting 2050 watts while drawing 9.2 amps from the wall socket which is just below the granny chargers rated 10A rating.

 

As you know a wall and portable AC charges are really just fancy "safety switches" (not chargers at all) that communicate to the EV regarding how many AC amps "max" the charger (whoops, I mean fancy safety switch) will allow to go thru it...and then the EV's BMS/on-board charger agree not to ask for more than that max amperage.  With the EV and fancy switch now in agreement the switch allows the AC to follow thru it to the EV where the EV's on-board charger converts the AC to DC to charge the battery...and the wall/portable charger monitor the amperage draw to ensure the EV don't pull more than the charger's max thru-put allowed....if the charger tries to pull more than the max then the charger cuts off AC flow to the EV.  Yeap, not a charger at all; just a fancy safety switch.  Technically called "Electric Vehicle Supply Equipment (EVSE)" in EV charging standards/regulations.

I’ll try to get those pictures for everyone tomorrow, thanks for the help so far.

 

I’ve also been in touch with wall box, apparently the do wall chargers and are gonna send an electrician out to do a free survey next week. 
 

the only thing with not going with the official one is that I’m guessing my landlord will want a good job and at least the official company would probably guarantee that.

 

I also did some detective work and saw some questions about wall chargers in my moobaans line group - all in Thai but I did a google translate, images attached.

 

finally, as the day I need to finalize the booking comes near I’m having some doubts….i know driving around Bangkok is not going to be a problem, specially if I can get home and charge but we often do day trips to the beach in pattaya - drive there and back in the day…..Also have my parents visiting from Europe and will want to take them to rayong or similar for a week holiday and this starts to make me feel nervous……how does one plan these trips? How do you know when and where to stop? Do you need to book chargers in advance? Does a 3 hour drive to rayong now require a stop in between?

 

sorry, I know these will be stupid questions for most! But I’m suddenly fearing all the longer drives I need to do….do you check with hotels if they have chargers and you have to reserve theme etc?

Well, if above posters are correct and based on the picture of your main circuit box you provider earlier your home probably has three phase power vs single phase.  So, you probably have three 45A lines coming into your main breaker box with a total amperage allowed across the three phases of of 60A...but the way three phases works each phase could possibly allow 45A.

 

And where the one poster said the "....and balanced the phase..." he saying the charger installer rearranged some of the circuit breakers in the main box to ensure the wall charger to dedicated to "one" of the 45A phases coming in.  But if your house does indeed have 3 phase power then you may be good-to-go, but the installer you sent the picture to below thinks you only have single phase power.   You need to have a wall charger installer actually look at your current electrical setup.

Whoops...I just noticed an error on my part...if you do have 3 phase power and based on your 60A circuit breaker your 3 phase meter is probably going to be a 30(100)A meter but the home builder ran smaller wire from the meter to  your home only only rated for probably around 60-80A per phase.  It just hard to figure out your situation without seeing the meter and the inside of your circuit box,  Have a charger installer take a look.

Landlord will want a god job: true - using a company like WallBox may even be better than BYD's outsourced providers just because you can send landlord the web site URL and he can see that they (or any other charger specialist) look reputable etc.

 

Day trips to Pattaya: I drive to Jomtien from central Bangkok regularly. If car is 100% charged when you leave, you'll get a solid 300km of driving so easily enough for there and back, with around 50 km range left as a reserve. I drive 110-120 on the highway. If you drive slower the range will be better. 100% charged when I leave usually leaves about 20% when I get home.

 

Longer trips: Never done one but pretty much every PTT station nowadays have DC chargers. You have to reserve a time on their app. Not difficult although requires a local credit card to link to account. If I was going to Rayong I'd look to see where nearest charger is to hotel, drive to hotel, drop everyone off, and then go and charge. Rayong is easily in range without needing to stop en route.

 

Hotel chargers: Don't have any real experience. I did stay at a hotel in Jomtien a couple of weeks ago (Bayphere) and discovered they had some chargers in the basement parking. First come first served. Didn't need an app - just scan QR and put in card details. Worked a treat and very convenient.

 

Bottom line is that EVs are fantastic for in town use and (in case of Atto with 60kW battery) round trips of up to 300km. Longer trips do require planning and are not as convenient. But if you don't do many long trips, I wouldn't worry too much.

 

As a postscript - if you have the cash for say 50% down payment, maybe look at second hand Attos? The re-sale has dropped like a stone thanks in part to BYDs discounting, so don't forget you'll be taking a big hit there when you buy new. If you could find second hand for say 650K, that would be a good deal.

This is my wall box, I had my electrician fit the 32amp plug and socket (lower right in the photo) so when I move I can unplug the wall box and take it with me.

 

The ABB wall box is a superb device and with 3 phase is capable of 22kw charging.

Excellent info....   What are we going to call these ???  "Super-Granni-chargers' ???

 

They're obviously way better than the standard granny-charger.  

 

By my Calcs - 7kW would charge my 88 kWh battery overnight  from 10-80% in 8.8 hours.

(and our EV has a range of NEDC 620 kms / WLTP 500 kms -  I'm seeing a more realistic 450 to 480 kms).

Those are three phase meters, specifically 15(45)A meters.  Based on your earlier posts from other people in your moobaan you mostly likely have a three phase main circuit box which means you have "three" 45A lines going to it.  If you can get a wall charger installed on one of those three incoming lines you should be good to go although the charger installer might have to "balance" the three incoming lines....by balance I mean move some circuit breakers feeding some circuits in your house "off" the phase to be used for the charger and moved to the other two phases "if possible." 

 

Now whether a installer under contract with a EV dealership like BYD will do that or not is unknown....you would have to ask them as the contracted installers seem to avoid "complicated" installations where they also need to mess around with circuit/breakers feeding the rest of your home.   You may need to get your own installer.

 

What you should do is go back to the installer that said you will need a second circuit/meter with your new found info to clarify to him you have a "three phase 15(45A) system" and see what he says.  He might have been assuming your had a single phase 60A system before which would need a second meter/circuit under the charger rules they have to follow.

Which Atto3 are you looking at ?

 

The BYD Atto 3 is available with two battery options:

Standard Range: 49.92 kWh battery, WLTP range 320 km

Extended Range: 60.48 kWh battery,  WLTP range 420 km 

 

Thus; Bangkok to Pattaya is about 150 kms, return is doable with the standard range, though that may cause 'some range anxiety' - understandable. Thus, if doing regular trips then the extended range may be preferred.

 

That said: There are charging stations everywhere and you can 'top up' very quickly. 

The Atto 3 supports a maximum DC charging power of 88 kW. When connected to CCS2 fast charger the battery can be replenished from 10% to 80% in approx 44 minutes.

 

Most petrol stations have these chargers. As do most shopping malls. 

 

The Plug-share website shows / maps where all the chargers are. It highlights what types are available. 

Also (in most cases) if they are in use, the cost and the power.

https://www.plugshare.com/

 

 

 

Also note: That there are many different companies operating these chargers, you'll need to be signed up for an App for each one (along with payment method) - some of them you can book in advance. 

 

The Plug share Map below is an example of what chargers are available in Pattaya.

We had a recent road trip - stopped off on the way back for a KFC at a PTT station while charging the car so road trips are not really a show-stopper - there plugShare maps show the extent of charging stations across Thailand.

They are basically portable wall boxes.

 

The functionality matches a wall box but they are much cheaper.

 

If you put a screw in the wall, they hook over the screw and make a semi-permanent installation.

 

If you wire a standard 16 amp plug to a portable 32 amp socket, you can also take this combination with you for hotels etc, just remember to select 16 amps or lower first.

 

[Pib]

@Yodarapper

   And if you wondering what the 15(45)A  rating really  means it means it's a 45A meter/service (it can handle 45A) with the 15A just meaning that will probably be its typically operating amperage...how much a person "typically" draws.   15A is also a key "calibration" point for the meter whenever they are tested/calibrated.     

 

Another example is a 30(100)A meter rating....that means it's a 100A meter (it can handle 100A) and uses 30A as the typical operating amperage/key calibration point.  

 

Just the way many meters are rated.

also note: That there are many different companies operating these chargers, you'll need to be signed up for an App for each one (along with payment method) - some of them you can book in advance. 

 

 

Speaking of charging apps as of 2 Dec 2024 at 7pm till next morning on 3 Dec at 8am the PTT charging network (which is probably the most used DC Fast Charger used network in Thailand) is transitioning from their old app to their new app at time of this post a little after 7pm. 

 

 And when I opened the old app a few minutes ago it no longer shows any chargers...basically unusable. And when trying to open the new app it gives the notice of being under maintenance/not active until 3 Dec at 8am.   

 

See below post for more info.

"If", repeat, if PEA recent policy change regarding getting a 2nd meter did not override below PEA guidance (date mid 2022) and since it appears you have a three phase 15/45A system then condition number 2 would apply to you.  PEA has always allowed a 2nd meter in those cases where the home owner justifies the current system can not be improved/upgraded for various reasons (such as cost) and then you could get a 2nd meter.   Go to below PEA weblink for more info...it's in Thai.  The snapshot below I google translated.

The Provincial Electricity Authority (PEA) recommends preparation before installing an EV Charger for residential homes or small businesses that do not have commercial purposes by checking the meter size, main wire size, main circuit breaker size and circuit breakers of the sub-circuits to see if they are sufficient to install an additional EV Charger. If the original electrical system is insufficient, you can choose to proceed as follows:
1. Request to increase the size of the original meter and improve the electrical system within the home to support the EV Charger.
2. Request to install a second meter if the original electrical system within the home cannot be improved.
