If it will make you feel better file a complaint with some agency, but you are probably pissing into the wind. Last year lots of people filed complaints regarding price reductions like you experienced and some even filed class action law suits. But as far as I know other than some govt spokesperson saying they are working the issue to get some compensation for some customers the Thailand Consumer Protection Broad announced in Nov 2024 that BYD had not broken any advertising laws which probably put a wooden stake in the heart of any complaints/law suits. See below Bangkok Post weblink. Also even before that in mid 2024 when the govt was negotiating with BYD regarding the price reductions some hi-so govt spokesman in late July said BYD had agreed to provide free charging "for a year" for some customers...but when BYD formally unveiled the free charging promotion it was only for 5 months and 3 days (1 Aug 2024-3 Jan 2025). https://www.bangkokpost.com/business/motoring/2911231/thai-investigation-clears-byd-over-discounts PUBLISHED : 29 Nov 2024 at 18:21

I don't expect major EV sales growth in the US over the next 4 years as the current administration (i.e., Donald and crew) are a "drill baby drill" and "protect legacy auto" bunch. But even Donald and crew can't keep the EV genie in the bottle forever....it will probably be 5-10 years before EV sales growth in the US really spikes. In the interim the rest of the world will generate the bulk of EV sales growth. It's great to have so many EV choices here in Thailand.

It will definitely take much longer for US folks to transition to EVs with legacy auto makers lobbying harder than ever for help from the US govt to protect their industry like in the form of high tariffs....and big oil is helping in that effort. But there are other major factors also such as the much, much bigger distances many Americans frequently travel and a charging network that needs much greater expansion. The US mainland (a.k.a., lower 48 states) makes Thailand-sized countries look like short drives to visit an in-law on a Sunday. Yes, most driving that people do is predominately local, but many people routinely also do long distance driving across multiple states and time zones.....l......o......n......g distances...I know I sure use to when living/working in the U.S. But the ICEV to EV transition will surely greatly accelerate over next 5-10 years (it will take a while) as US consumers demand much cheaper EV vehicles that they keep hearing about other countries having like in China, Europe, Thailand, etc. Legacy auto and big oil can't keep the EV genie in the bottle much longer especially for young adults who are more comfortable with technology changes.

See below Bangkok Post 26 March 2025 article for full details. And seems BEVs and PHEVs had a nice sales increase (59% and 209%, respectively) when comparing Feb 2025 to Feb 2024 sales....can't say the same for ICEV and HEV. https://www.bangkokpost.com/business/motoring/2987518/car-producers-postpone-export-models

And my mid January prediction (below) of the Sealion 7 dropping in price by at least Bt150K by 1 July 2025 has come true way before 1 July with a Bt150K price reduction in the AWD model. This ongoing price war don't care if it's a super popular/on backorder or unpopular model....the cut throat pricing will continue. Heck, by 1 July BYD could very well sneak in another price cut of around Bt50K on one of the Sealion 7 models in the form a straight out price reduction or smoke and mirrors cash back type promotion. Both EV and ICEV manufacturers are still at war---price-wise!

As more and more ICEV drivers transition to EVs I sure hope they can handle the increased power/torque/speed of an EV. Probably going to be a lot more neck injuries caused by increased acceleration & G-forces...especially for females with their delicate necks. Of course some females can not experience neck injuries as they are pure demons which can rotate their heads 360 degrees. 😜 Maybe the government should require special driver license for EV drivers...a license that includes training in acceleration, G-forces, etc. Heck, I'm not sure, but I don't even think governments started requiring a driver license until the technology transition from horse & buggy to motorized vehicles" began over a 100 years ago. Maybe this technology transition period of ICEV to EV should require a new special license--and of course at a higher price to ensure a new source of tax revenue. 😁 P.S. Above is all sarcasm. 😉

From googling this it seems the pro Just doing the every 3-6 months discharge to at least 10% and then slow charging back 100% to recalibrate the SOC indicator and range guess-o-meter "as recommended by BYD (and even Tesla) for LFP traction batteries" is not the core case. It's either some software glitch or 12V battery problem. From googling I came across lots of folks who ran into this issue even when their high voltage traction battery was at a high level SOC. Some just came back to the car after being in the mall for a few hours and the Seal was dead/asleep. Some figured out it was caused by the 12V battery running down/entering sleep mode when the hood, door, etc., was left open for an extended time like overnight or a few days. But then others ruled out 12V battery drain as the problem but some software glitch telling the 12V battery to go night-night. As with a lot of car issues, there can be more than one cause of a problem. But yea, I would definitely have your 12V battery checked out....have a health/capacity check done....check for loose/corroded terminals, etc. And I would recommend you install a Bluetooth 12V voltage monitor on your battery as this will allow you to easy see and track the 12V battery voltage/SOC/temp.....greatly help to spot issues well in advance and/or confirm whether the battery is asleep/dead without needing to access the battery as the mobile app used with the monitor will tell you what is going on 24/7. I installed Ancel BM200 Bluetooth 12V Battery Monitors on both my 2023 BYD Atto and 2009 Toyota Fortuner about a year ago....the monitor works like a charm....has a voltage measurement accuracy of 0.03V (30mv), only draws 1.5ma working current, and includes 30 days memory. Cost is around Bt500 plus or minus Bt100 depending on promotions, discounts, etc. I brought mine off Lazada for around Bt420 including shipping around a year ago.

In BYD vehicles that KmH/100Km consumption estimate is like its NEDC (Not Even Damn Close) range estimation. Like my Atto has a NEDC range rating of 480Km. And if I use the Atto's consumption estimate (snapshot below) I'm consuming 12.7KWH per 100Km after 35,513Km of driving...about 99.9% of those kilometers were done in ECO mode with light foot driving here in and around the greater Bangkok area and bordering provinces with very little of those kilometers exceeding 120KmH and also not a lot of terrible Bangkok traffic since I don't live in the highrise, central Bangkok area where living half your life at a stop light/in a traffic jam can be the norm.....my Bangkok driving is where I can usually move along in the 50-80KmH ballpark. A/C set to 22C. Since my Atto Extend range model has a 60.48KWH battery and using the consumption numbers it translates to a range of 476Km....yea, right, maybe if using NEDC type math. Real-world I get around 400 to 442Kmh range depending on the time of year and of course the type of driving....a person gets better fuel efficiency during the cooler parts of the year as the air-con uses fewer electrons. My last two real world range tests where I make sure I use a light foot in driving, very little to no driving faster the 90KmH, "and" taking the SOC down to less than 10% (like even to 1%) was back in Sep 2024 and Jan 2024 where I got a range of 424Kmh which does exceed the Atto WLTP 420Km range rating but well short of its Not Even Damn Close (NEDC) 480KmH range rating. In some previous real world tests I've got as high at 442Km range. Do "not" base your BYD vehicle's range estimation on what its consumption reading tells you....base it on some real world range tests where you drive the car down to around 10% or less. But even driving down to say around 25% SOC can also give a fairly close real world range estimation. The BYD consumption guesstimate appears to not count total consumption as at least on my Atto...it gives a reading that is around 15% low real-world. Maybe it don't count A/C consumption which averages around 1.5KwH after the cabin has cooled down on hot days....and can even reach up to 4KwH when first starting the car if its been setting in the bright, hot sun. Maybe it don't count the time/electrons you are eating when not moving like at stop lights/stuck in a traffic jam, idling in the parking lot, etc. And maybe BYD just tweaks that consumption algorithm to give Happy Face type readings that always seem to be close to the car's NEDC rating.

He must have found the sweet spot speed in the 80KmH ballpark. I have noticed with my Atto its sweet spot is in the 50-80KmH ballpark....but below and above this ballpark range the range decreases significantly. Also, in a couple of other Sealion 7 range tests Bjorn did with the Sealion 7 with 82.5KWH battery he only got a range of 446Km at an average speed of 90KmH and 312Kmh at 120Kmh.

Extrapolating that to running the battery down to 0% would indicate a real-world range of around 449Km which sounds about right for a Sealion 7 Performance or AWD (I don't know which model you have) with NEDC ratings of 567 and 542Km, respectively. I kept my Atto in ECO mode for the first 3,000Km and since then (around 18 months now) I've kept it in ECO mode about 99.9% of the time. Only use Normal or Sport mode (which burns electrons a little faster) whenever I want to do some tests, maybe show-off the get-up-and-go to some passengers, etc. But ECO gives plenty, more than enough power for quick passing, quick get-away if you are the driver for bank robbery, etc.

Oh, my BYD Atto with a 60.5KWH battery is rated at NEDC 480Km/WLPT 420km....and I can get 420Km real world range with ECO driving. It's a lot more than I need for day-to-day driving....and needing to charge once on a long trip is not a big deal. HOWEVER, BUT, I would like to have an EV with approx 750Km real world range. Do I really "need" an EV with such a range? No. But do I "want/desire" such an EV? Yes. And I would like to have a full size SUV EV with that save 750Km range....heck, I would even settle in the interim for a 500Km real world range on a full size SUV such as a Fortuner size. And EVs with significantly longer range will pretty much kill-off a main reason lots of people don't buy an EV---range anxiety. EV sales will surge!!

Faster charging batteries is a good thing "if", repeat if you can find a DC charger with the high power to provide the required charging rate. Like a 80KWH EV battery with a 5C rate would require a 400KW DC Fast Charger to fully charge in 1 hour "if" the battery could maintain a 5C rate from zero to 100 SOC which is highly doubtful as that highest C rate will only be over a portion of the battery's charge curve. An 80KWH EV battery with a 10C rate would require an 800KW charger to take full advantage of the high C rate. How many 400KW and 800KW chargers have you seen around Thailand--probably zero. And of course a high C charge rate does nothing to improve your charging speed on your home 22/11/7KW wall charger. More powerful batteries/higher KWH without increase in physical size is what I would prefer....that is, like a 160KWH battery which is the same physical size as an 80KWH battery....give you a ton of range and/or be able to give good range to larger vehicles like a full size SUV say the size of a Toyota Fortuner or Isuzu MX-X SUV. Throw in faster charging/high C rate as ice cream on top of the pie....yummy.

And here's an article with partial quote with more details on the BYD ultra fast charging blade battery that can charge at 10C, Super-E 1000V/1000A platform, etc. This truly seems like a BIG step forward in batter battery technology that actually going to reach the common man at an affordable price very soon. However, it will not improve the charging speed at the typical 120KW DC charger, 7KW wall charger, etc. What I also hope to see soon is just EV batteries that can hold a "lot more KWH" without being physically bigger which will very significantly increase range. Faster charging and higher capacity batteries will drive hasten the continuing transition to EVs. https://cleantechnica.com/2025/03/17/byd-launches-1000-volt-ev-platform/

Didn't know there was a phone number login option for Thailand. I have to login with my email address and PW. Now once logged in whenever I need to open the app I just using biometric/fingerprint to get the app fully operating....no email and PW entry required. Only if I manually logout...that is click the logout icon do I have to login again using my email address and PW.
