- cogman10 4y agoTrue. Though the damage is low from hitting 100% which is part of the reason why this is a "just leave it at 100%" rather than a "hit 100% once a week". That said, I'd probably do 90% as the max and 100% on the weekend if I owned an LFP vehicle.
- dangrossman 4y agoThe average American, buying a ~250 mile range EV, would only need to plug it in to charge once a week. Maybe twice. So, just charge it to 100% every time you charge it.
- SigmundA 4y agoNot like they are just using battery voltage for SOC, they are coulomb counting with a shunt, so you only need to charge to 100% once in a while to account for drift. LFP gets 2x the cycle count at 100%-0% as a NMC does at 80%-20%. Due to its lower cell voltage it has less voltage driven aging than NMC. Elon: "I’d personally slightly opt for iron pack, as it wants to be charged to 100%, whereas nickel prefers ~90%." https://twitter.com/elonmusk/status/1431040308943364097?lang=en https://twitter.com/elonmusk/status/1431040308943364097?lang...
