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.

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

100% normal - fast 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.
