2015 Spark EV 110 volt to 240 volt

Spark EVs have a ~105 kW electric motor. Cruising at 60MPH, the motor is likely drawing about 10-15 kW from the battery continuously. The battery is designed to deliver 100kW. I would think that charging at 1 kW vs 3.3kW vs 6.6kW is pretty trivial, especially considering the battery has active liquid cooling. It would be heat that causes degradation. I assume the liquid cooling also functions while charging. I would not worry about 240V charging. Now if you charged it every day with DCFC at (unsure of the rate, speculating 80% charge in 20 minutes) 50kW, that might shorten the battery life...

Thanks! I’m going ahead with the level 2 charger.

My intention is to add a 240 volt charging station to the house, set the amp draw to a maximum of 30 amp and charge the Spark from there. A friend mentioned that pushing more voltage into the batteries will degrade them much faster than the original 110 charger. Is there any truth to that?
Thanks

Sounds like your friend is talking about DC Fast Charging which you won’t be doing at home.
