Why you need to charge LFP to 100% Ok so I have seen many questions lately about LFP and charging to 100%. The battery cells do not have an inherent requirement to be charged to 100% The reason you should still charge to 100% at least once a week, is that the BMS (battery management system) will lose track over time of where the state of charge is. Why does this happen then, and why don't the non-LFP batteries need it? It comes down to the voltage curve. LFP has a very flat curve, or in this extreme example of the attached photo, maybe even fluctuates up in the middle of the discharge curve. (Not very common, but illustrates the issue at hand) This mean that the BMS cannot rely on voltage alone to determine SoC. However this then means that it has to use the Ah in and out to determine how much is left. The problem with this is that the available Ah also fluctuates with factors like temperature and discharge rate. This is why you need to charge to 100%, to give the BMS a reliable point to start counting down from. As the battery is charged to full, the voltage spikes, and this tells the BMS that the battery is full. NMC and most other lithium batteries have a more linear curve, which allows the BMS to use the voltage also to determine the current SoC, which negates the need for this calibration charge. Hope this helps. https://www.reddit.com/r/TeslaModel3/comments/1b7dr08/why_you_need_to_charge_lfp_to_100/ Updated especially for you already... you're welcome!

Here's your homework for today: https://youtu.be/QRPze4f0gsQ https://www.reddit.com/r/TeslaModel3/comments/1b7dr08/why_you_need_to_charge_lfp_to_100/

Childish as usual, didn't expect anything else from you.

But most LFP batteries charge much slower and they need balancing a lot more often than NMC so they are even more inconvenient if you can't charge at home.

I think NMC batteries require balancing about once a month and for me this would be quite inconvenient without a home charger. If an equalisation charge has not been carried out for sometime, the message centre in the instrument pack will display 'Please Slow-charge the Vehicle'.

What about when she needs to balance the battery? I believe this only works on slow chargers and you have to spend a long time charging to 100% and then allow extra time for the balancing.

I'm by no means an expert but I think while this is true, the startup spike is very brief so it's not as bad as it sounds and it won't contribute a significant amount of the overall energy usage. The interesting question is when is it worth upgrading a perfectly working older fixed speed air conditioner to a newer inverter model? I think in most cases it's worth keeping the old one until it dies.

Unfortunately the government has done their best to discourage the use of NGV by incessantly raising the price...encouraging many to switch back to subsidised dirty diesel or LPG.

Sounds like your typical Thai employee who is absolutely clueless about the product they are trying to sell. I expect it's supposed to be 800,000 THB.

MG 4 updates ...now available in orange too. Official price (Thai assembly) Comes with campaign promotions as follows: Guaranteed vehicle quality for 4 years or 120,000 km. Battery warranty for 8 years or 180,000 km. Free first class insurance for 1 year Free 1 set of MG HOME CHARGER Free installation fee for MG HOME CHARGER Free 1 set of V2L cable

I think EVs catching fire under normal usage is indeed very rare but when they are involved in a severe collision then the risk is much higher especially with NMC batteries. LFP batteries are generally safer. I believe the Venice bus crash below used LFP batteries but the bus may have landed on high voltage train tracks which caused the batteries to explode. https://www.bbc.com/news/world-europe-67001518

Looks like the prices of all cars in Thailand are dropping like a stone... https://autolifethailand.tv/discount-official-suzuki-ciaz-thailand/ 150k discount on a brand new Suzuki Ciaz. How long before you break even with the lower fuel costs on the MG 4 for the extra 300k?

Are you trying to tell me a wallbox is worth 70k baht? Let's say a rather generous 20k then it's still a 50k saving.

https://www.car250.com/mg4-th-2024-1.html Another price cut by MG as I expected. All of the early adopters rushing to buy at the end of last year are looking rather foolish now...

They know they will have massive depreciation when a newer model comes out in a year or so that is cheaper, has a bigger battery and charges twice as fast.

How stupid can Western governments get? Forcing Western companies to buy imaginary carbon credits from foreign companies... Energy Absolute must be laughing all the way to the bank.

Let's hope they use some of that money to stop the monorail wheels and conductor rails falling off again!

You said most of the chargers in Thailand are DC chargers but from the website you quoted there are: 2,827 Type 2 AC chargers 1,471 CCS DC chargers Obviously there is only one small child here who doesn't know the definition of the word "most".

Please look up the definition of the word "most" in a dictionary.

You early adopters are in the golden age of EV charging. It's only a matter of time until there are long queues for fast highway chargers like the UK is experiencing now (with the public charging cost higher than petrol).

So how many fast DC chargers are available in Thailand? I think Thailand has the exact same problem as most of the public chargers I see in shopping malls etc are the slow AC type. Even if there are plenty of fast DC chargers available now, at the current rate of EV sales I highly doubt the charging infrastructure will be able to keep up and it will be absolute carnage for longer weekend trips.

Has anyone tried using a car registration (blue) book as proof of address?

Surely it should be 15%? SCB told me the tax deduction was 100% last month because they were collecting taxes on the 20K of interest I already received in June and October. Hopefully at the end of this month the tax deduction will be a lot lower.

He'll be out in a couple of years...TIT.

I follow this thread because I'm interested in EVs and I occasionally "chime in" to set the record straight when people like you try to compare apples with oranges and refuse to even consider the disadvantages of an EV. You seem unwilling to enter into a balanced discussion weighing the pros and cons and you always try to cherry pick your figures like solar charging, top spec ICE price compared to lowest spec EV price etc. to support your arguments.
