About electric vehicle. If you add the maintenance cost for battery, how does it fair compare to gasoline vehicle? On cost we have to pay. (lemmy.world)

I heard someone said that, at the end EV will cost you almost the same as gasoline vehicle, if you have to change the expensive battery every so often. Can someone please give me more info on this? Thank you so much.

It's worth noting that while NMC batteries shouldn't be charged over 100% for daily use, LFP batteries should be charged to 100% at least weekly.

LFP batteries are not damaged by being at 100%, and due to the flat discharge curve, the controller only knows how charged the battery is when it's near 100%. Most of the time it's calculating the charge left based on how much energy is being used.
Over time, that guess is going to get less accurate. Charging it to full will reset the guess, and keep it accurate.
Only charging to 80% can cause the guess to be off by more than 50% (after quite a long time), leading to the battery running out when the car thinks it has at least 50% left.

If you don't know what battery your car has (and don't have access to the manual), assuming LFP is safest. Any EV sold after 2022 is likely to use LFP (unless it's a high performance car), and EV's sold before 2020 are probably NMC.
New battery chemistries are coming on the market every year, so don't rely too much on this comment.
