Leafs don’t have active battery management. As far as I know, they’re basically the only widely available EV in the US with this problem.

Just replace the car, as much as that sucks.

Apparently Honda IMA (NiMH) 1 and 2nd gen not only lacks active thermal management, it also doesnt have any BALANCE management!?!?!
