Battery temperatures rise sharply after DC charge

[sarinotropeano]

I have noticed that the battery temperature goes from 76* F to 126-131* F after a fast charging session. Has anyone else seen this? Is it normal?

Yes it could be normal but it depends also on the external temperature. Car warms up the battery before a fast charging but if the outside temperature it’s not high it could take hours to cold down.

Yeas it could be normal but it depends also on the external temperature. Car warms up the battery before a fast charging but if the outside temperature it’s not high it could take hours to cold down.

I have an unheated garage, so this is a feature not a bug for me .

100% normal - fact charging both creates heat and also needs heats for the cells to "accept" the higher power - the car will actually warm the battery to reach ideal fast charging temps…

this 100% normal across all current generation EV's - future/different battery tech may be different, but nothing so far.
