Can’t charge at home

96% after less than 2 years - i guess the car is a leased one which was always charged to 100%. If you buy don't charge to 100% on a weekly base. Charge to 80% that will expand the live time of t he LFP battery. Most comfort way would be to charge daily at home to 80%.

If I change it to 80% the cars tells me to keep it at 100% since it’s an LFP battery 🤔 I only charge it to 100% if I’m going to use it right away

Charge to 100% with LFP. You don’t need to stick to 80% limit. 100 all the way

That’s what I thought, thanks man 🙏🏻

Pick up my Model Y tomorrow. I’ve been doing some extensive research because of excitement 😂

Same 😂

LFP doesn't like staying at 100% either, the effect is just less pronounced and LFP has a better cycle expectation to begin with. But LFP needs to be charged to 100% so that the BMS can calibrate correctly. In contrast to NMC batteries the voltage difference between full and empty is very very narrow so the BMS can't calculate battery capacity by looking at the voltage but looking at charge and discharge values. As with cars there a many tiny ones with each acceleration and deceleration which can't be accurately tracked either. So the BMS needs frequently the starting point 100% charge to deliver usable range values. Since car manufacturers need to play safe here the tradeoff calculation goes pro 100% charging. NMC batteries don't need that so 80% is the recommendation. The bottom line is that you don't need to charge to 100% all the time but you should do once a week and before going in trips where you use up most of the capacity.

Engineering Explained has a good video on this topic. The reality is that LFP batteries do degrade like other batteries when kept at a high state of charge. However, they do handle the high state of charge a little better offer time. If you’re only charging once a week, go to 100%. However, I would drop the charge down a little if you’re charging every day and only charge to 100% once a week.

Thanks for the input 🙏🏻

Might charge two times a week, I guess I go to 100% then?

Probably would be fine. It sounds like you’re not putting a ton of miles on the car. I would be a little more cautious if you live somewhere where it gets extremely hot or cold. Very hot and cold weather is a big factor in degradation related to the state of charge.

Extremely I’m not sure about but during winter -15~20 During summer +25-30~

Tesla recommends to always be charging so you’re not at best practices right off the bat. HATED EV life in an apartment so good luck dude.

That I know but the question is more how this will affect the battery and if it ever will

It must…otherwise Tesla wouldn’t even bring it up. Smaller charge cycles 60-80% is WAY better than deep discharges and constantly high SOC. Awful awful, I would never do that again.

Not on the LFP one it’s recommend to charge to 100% once per week. Whenever I charge which is like 1-3 times per week it will either be 100% once and then the other two prolly 80~

Do you know why that is? Probably not. Once a week is fine but you already said it’s more than that. I’m just telling you what Tesla says so if you know better why even ask?
