Would that be too warm for an E-car battery?
Still much cooler than Li batteries when they catch fire. :)
A clever engineer would find ways to capitalize on that heat, as I mentioned it might be useful to supplement heating the interior in winter.
Pipe water around it for the on-board espresso machine?
Or more seriously, use the heat to drive the AC in summer.
Should not be a major barrier to EV use so long as it is not rushed into production like a certain vaccine.
