I looked at that weblink that @matchar gave but for my Atto 3 and it said 1st leg distance was 238Km and 2nd leg distance 87km for a total of 325km. 

 

They must be dragging an anchor or something in doing those tests because my Atto 3 real world range is around 400Km in the hottest part of the year and around 440km in the coolest part.    That is from 100% down to almost 0%. 

 

Using that weblink's methodology, my 1st leg range would be around 378km and 2nd leg around around 151km for a total of approx 529km.   

 

Yea, they need to redo their testing without an anchor.

It's all about the speed you drive. Those figures are based on motorway speeds. Driving at 80 km/h or around town will get you much further but most people drive 120 km/h on motorways as that's the speed limit.

from 100% to 10% would mean about 6 hours (450 km) of driving time without stopping based on my driving pattern on my monthly round trip!!!! oh dear ....

 

this would not be possible for me personally because i don’t have an elephant bladder and after about 2 hours of driving, i prefer to take a proper break (toilet, coffee, snack) ... 

but i’m aware there are drivers who empty their bladder into bottles while driving and believe that every minute saved on the road is worth gold ... 

 

 

You must have either have a large battery or drive slow or both. Driving at the speed limit of 120 km/h on motorways quickly drains the battery of most EVs.

If the power of Thai charging stations is limited then having a large battery is more important for long distance trips. Unless you enjoy taking a 40+ minute break every 2-3 hours to get back up to 80%.

Silly specs for high end buyers, and for most drivers, especially local, knock around town drivers, not needed or desired for the additional cost.

 

Not that you'd be buying a new BEV any time soon.  Maybe about the time that Toyota sold state battery will actually hit the market, if ever 

 

Apologies in advance, if I've mistaken you for one of them ... ICEV drivers.

Not silly for people without endless time on their hands. The 1-stop range is important for people who just want to stop for 15 minutes to charge on longer trips.

For your beloved MG ZS the 1-stop range is a quite pathetic 257km.

I was intrigued by these 2 cases.

 

Both of them had a degraded battery due to higher Internal Resistance [IR], which resulted in a battery not giving enough power.
Unfortunately during yearly checks IR is not measured and reported to owners, because it is not easy to measure. 

I have been wondering what may have caused this, so I asked both perplexity.ai and gemini for help:

1) I looked first at the design

 

BYD blade v1 cells are longer [96 cm] than prismatic cells like CATL Shenxing v1 [17cm], thus have a higher nominal IR, 2 times more than CATL, according to perplexity.ai.

 

Cooling, heat and IR degradation are related.
For cooling there is a layer of cooling channels on top of all cells, not in between the cells. CATL has cooling channels in between.
Therefore blade v1 is restricted to 1-2C fast charging, while CATL Shenxing v1 from 2023 can do 4C charging.
If you follow youtuber Bjorn Nyland, you also know about the rapidgate issue.

When rapid charging BYDs, sudden drops in power during charging, because BMS detects too much heat in the cells that it lowers the power to charge.

 

2) wrong practices owner
I asked Gemini what the byd owner could have done wrong 

- frequent dc fast charging generates heat accelerating IR degradation
- fast charging when battery already hot 
- charging immediately after fast driving
- parking and charging in hot sun
- driving aggressively
- constantly charging to 100%  and storing at high SoC

Thus heat in cells not properly managed => increased IR => causes bigger voltage drop [ less power ] and more heat generation [ due to higer IR ]

 

3) causes outside fault of owner

I asked if issues in the cooling system could also cause this issue

 

Yes, confirmed by Gemini:
- dirty AC condenser [ Thai EV mechanics advice to clean  every 40k km ]
- low AC refrigerant [ well this would be noticed by the owner ]
- coolant leak outside the HV battery

- coolant leak in the cooling pad inside the battery

 

4) other scenario's in rainy season
- water ingress thru battery valves

- water ingress thru holes of case bitten by rodent and not noticed by owner [ known issue with atto3 and dolphin ]

According to gemini not very likely scenario's and it would trigger other BMS faults causing a vehicle shutdown
 

Those BYD blade v1 batteries seem a bit outdated now...it's about time they launched v2 in Thailand.

Personally if buying a new car, I would choose a different brand that has a newer CATL battery capable of at least 3C charging.

It's interesting how most car brands in Thailand only guarantee their batteries for 160,000 km.

Modern batteries are supposed to last for 500,000+ km but it seems like only MG are willing to put their money where their mouth is (and they use CATL batteries).

But nobody knows yet how MG will honour their "lifetime" warranty if the battery craps out after 9 years.

How do they define the "lifetime" of an EV?

Regarding the warranty period, AI says it varies by country/region with Thailand being one of the countries with a lower/shorter warranty period on vehicle and battery.   So, has there really been a warranty change (reduction) for Thailand or it's still the same but just happens to be lower/shorter compared to some other countries?

 

 

Yes they have reduced it...AI overview is typically wrong. This old article confirms it used to be an 8 year vehicle warranty and 240,000 km battery warranty.

Strange that they seem less confident in their newer LFP battery than the old NMC one...

It looks like the price-war 2025 is getting started way before the Autoshow  - color me intrigued, it could be a bloodbath:  

 

Here is a shot into the void by Deepal (although I don't see how this could work for them against the BYD SL7 base model)

Changes to Deepal S07 (MY2025):

Battery replacement from NMC 66.8 kWh to LFP 68.8 kWh

Upgraded to support DC 3C Technology charging from 87 to 163 kW.

Change the suspension and adjust it to reduce sway and improve road grip.

Change the front bumper to the same color as the car.

Change the lower side edges to the same color as the car body.

Change the lower rear bumper to a new design.

Replace the 3rd brake light on the roof with a new design.

Change to 20-inch alloy wheels, new design

Cancel exterior body color Cosmic Yellow

Adjust the vehicle warranty from 8 years/160,000 km. to 5 years/120,000 km.

Battery warranty has been adjusted from 8 years/240,000 km to 8 years/160,000 km.

The price is 300,000 baht cheaper than before.

MGs latest EV hasn't been selling so well...another price cut on the D model (from 719,900 last time).

Two new sunroof models introduced and the long range battery changed from 64 kWh NMC to 62.2 kWh LFP...all three versions are now assembled in Thailand.

This latest upgrade, by BYD, will focus on the powertrain, with the new Atto 3 switching to a TZ200XYC permanent magnet electric motor , the same one found in its bigger siblings, the Seal EV and Denza N7 electric cars. This results in a maximum output of 230 kW (308 hp) , or 107 hp more than the current model.

With the use of this new electric motor, the facelifted Atto 3 is expected to feature the same 800V high-voltage system as the Seal EV. This will allow it to support DC fast charging of up to 150 kW , almost double that of the current model, addressing a key weakness in charging speed.

https://th.carnewschina.com/2025/10/11/byd-atto-3-ใหม่ยกระดับ-ปรับความแ/

"While no further details are available, the facelifted BYD Atto 3 is expected to launch in the Chinese market later this year, bolstering its competitiveness against rivals in the fiercely competitive electric vehicle market."

What launches in China is rarely available in Thailand...the Thai versions are usually old tech 1-2 years behind.

The BYD Seal in China has had 800V architecture for a long time already but it's still not available here.

While criticising the MG3 for failing one of the safety aspects in the Euro Ncap tests lets not forget that they are not alone.

 

Do you have an example of any similar faults from another brand?

"The result of the seat latch mechanism failure led to extra impact on the driver dummy’s right leg, while also making its head ‘bottom out’ against the steering wheel rather than the airbag. This meant head protection in the MG3 was downgraded to ‘adequate’ and leg protection ‘poor’. Euro NCAP said that since it began crash testing in 1997, this type of failure had “not been seen before”."

Special price calculated from the NEW MG3 Hybrid+ D model, regular price 579,900 baht, available for the first 20 units only (after dealer discounts).

20 units is quite low ... how do they count it ? Per dealer, per province or in the country ?

I'm guessing only 20 nationwide for the special racing edition paintwork. But I expect there are plenty of the regular colours at 499k.

I think the MG 4 is a much better buy if you can afford the extra though. Or second hand they start from around 400k.

New, lowest trim spec.

I saw 579k on the mg website, but he says discounted to 500k for cash.

They made the offer by email after he had a test drive then walked away.

499k is the standard price now. MG are just more discreet with their discounts to existing models than BYD to avoid annoying the previous buyers.

Another price cut:

What's that? Another price cut? Well I'll never...

Tell me what the final price is then.

That depends on the state. Each state charges different fees to register new vehicles.

Northern Territory:

The NT offers free registration for eligible plug-in electric vehicles (BEVs and PHEVs) until June 30, 2027.

This includes a waiver of stamp duty fees up to $1,500. 

Victoria:

Victorian registration fees are calculated using a "fee unit" system, with a set fee per unit.

Electric vehicles receive a discount of $100 on their registration fee.

New South Wales:

NSW has a stamp duty concession for EVs up to $1,500 and free registration until June 30, 2027.

However, a road user charge of 2.5c/km for EVs will be implemented from 2027 or when EVs reach 30% of new car sales. 

But what's important is the price Zeekr are selling it for, which is 1.2 million baht.

And the final price after the ORC & LCT (if any) ....

 

.... "My local Zeekr dealer sent me an info pack for the 7X, $2k refundable deposit, estimated pricing (before ORC by taking current Zeekr X pricing and differential to Zeekr 7X pricing in China) as follows:

 

Zeekr 7X RWD: $65,000 – $70,000 = ฿1,371,026.15 - ฿1,476,489.70

Zeekr 7X RWD Long Range: $70,000 – $78,000 = ฿1,476,489.70 - ฿1,645,231.38

Zeekr 7X AWD: $78,000 – $85,000 =  ฿1,645,231.38  -  ฿1792880.35 " ...

 

No mention of wall chargers or 1 yr insurance included.  Thai price are 'all in'

 

Looks about the same prices to me ... nice try

 

You are talking nonsense as usual. You are quoting estimated pricing before the cheaper official price was announced.

"The $57,900 before on-road costs price is for the entry-level 7X RWD (rear-wheel drive), with the 7X Long Range RWD $63,900 before on-roads and the top-spec 7X Performance AWD at $72,900 plus on-roads."

"An additional promotion for the first 1000 buyers has been extended until August 18.  It gives buyers two years of additional warranty and roadside assistance on top of the standard five years, as well as any paint and cabin colour choice at no additional cost.

It also includes a 7kW home charger, Type 2 charging cable and 10-Amp mini portable charging cable, which will be offered beyond August 18 through to September 30."

 In April, Thailand made its first EV shipment of 660 vehicles.

The tweaked scheme is forecast to take EV exports to about 12,500 units this year and 52,000 units in 2026, the board said.

https://www.reuters.com/en/thailand-adjusts-ev-policy-ease-production-requirements-target-exports-2025-07-30/

12,500 ev exports in 2025 a projected increase of 316% on 2026 or 52,000 if the ssame projected increase is applied for 2027 that would be 216,320 ev exported

Currently Thailand is in negotiation with the EU on a Thailand-EU FTA

MG was looking at Thailand-EU ev exports in 2024 

Chinese EVs manufactured in Thailand must contain over 40% locally made parts, so they can be considered as “originated from Thailand”.

“Thailand never exports automobiles to Europe, as there has been no trade agreement between the two regions,” he said. “It is estimated that Thailand will face import duties of 10-20% if it starts exporting EVs to Europe.”

https://www.nationthailand.com/business/automobile/40040855

Even if we exclude the UK and Europe Thailand exports to many countries as part of the ASEAN FTA

The ASEAN Free Trade Area (AFTA) comprises all ten member countries of the Association of Southeast Asian Nations (ASEAN): Brunei, Cambodia, Indonesia, Laos, Malaysia, Myanmar, Philippines, Singapore, Thailand, and Vietnam.

So let's see...a domestic production capacity of let's say 600,000, minus 52,000 predicted exports in 2026.

That leaves around 550,000 for the Thai market to absorb.

I stand by my prediction of significant discounts in Thailand going forwards.
