It’s a neat conversion for EV charging. 7kw x 2.5 miles per kwh is 17.5 mph. Most EV onboard chargers top out at 11kw, 27.5 miles per hour. So from the battery’s perspective, 22kw is it’s normal discharge rate at 60mph.

waitmarks@lemmy.world 3 days agoAny AC load you can throw at an EV is effectively “slow charging”. My car supports a maximum of 9.6kw from an AC charger, but up to 150kw from DC fast chargers. Even with the fast charging, its not like a phone, it has active thermal management which will cool the battery and slow down the charging if it gets too hot. phones don’t really have that and is mainly why they degrade faster if quick charged.

Can you source that?
