Comment on BYD Reveals the ‘World’s Longest-Range EV’ as American Auto Industry Struggles to Keep Pace
Cethin@lemmy.zip 2 weeks agoNever heard the “above 80%” thing. I’m pretty sure you’re wrong about this. With lead-acid batteries, this was optimal. I’m pretty confident that lithium ion batteries it’s best to keep the charge as high as possible. Ideally you’d only ever use it fully charged. It’s health is harmed by draining it low/fully.
I don’t own an EV, but I know enough about it that I’m pretty sure this is the case. You should look it up for your vehicle though. This advice also applies to phones and other lithium ion batteries too. Lead-acid was damaged by keeping the charge high, but lithium ion is damaged when low, and almost all devices are lithium ion now.
Lead acid batteries like to be kept fully charged all the time and don’t like to be discharged below 50% state of charge.
Lithium batteries like to be kept around half charged. They degrade quicker when kept at a high or low state of charge. Running lithium batteries from 20-80% does extend the lifespan, but charging to 100% is fine when you need to go on a longer trip. Just don’t keep it at 100% for long periods of time.
I think the BYD blade batteries can go down to 20% and up to 100% weekly. Though tbh I probably keep mine too high, I should lower it a bit closer to 80%…

confidently incorrect.
You could disabuse yourself with a quick search.

Oh, sorry. You’re right. I forgot I have my phone on a battery saver mode where “fully charged” is not fully charged.
