———————————————————————————
Spark EV owner here. the kW charging rate and AC charging times on ABRP has always been wrong, it's set to 7.2kW when in reality I have a 3.3kW charger.

I'd like to be able to edit my EV's AC charging power in vehicle settings so ABRP can estimate times accurately. I had a bug report I filed a while ago and it never got attention, so I'd like to edit the settings myself.

It also makes sense for car modders that change their stock charging.
