Informative (as gothitjulie’s posts generally are) but depressing that this is the reality we are being forced to confront.
Agreed, but a couple of mitigating factors here, the first is that battery technology is improving & is already far better than it was a few years ago as manufacturers introduce active heating & cooling to their battery pack & adjust the cobalt ratio. The second is that for many people, rapid & ultra-rapid charging isn’t something they need to do very often as they charge using AC chargers at home/supermarket/street lamp etc.
When I’ve charged outside my home at -5C this winter I’ve seen no slowdown in the 7kW charging speed until it reaches 98% when it slows as the BMS balances the battery, it does this at any temperature & it needs to be done about once a month to maintain battery health over the long term.
Hint: If you balance charge to 100% then don’t leave it sitting at 100% for a length of time as it degrades the battery. Driving it the next day to reduce it from 100% is absolutely fine.
Not sure if anyone remembers going to foreign climes & leaving the car sitting for two weeks, well, ideally leave it sat at around 70% charge, although anywhere between 20-80% will be fine. Same with a fossil, in hot weather the fuel will expand so you’d not leave it with a full tank.
