That is being tested using sub zero liquid cooling. Problem is, it takes are charging station with a sub zero cooling system and the connectors and tubing to recirculate that in the battery module. Odds are that may only make it into the niche transport area - the momentum for installed air cooled systems is just to high.
Isn't the cold a bigger issue than the heat for lithium ion? Would need a battery warmer if anything, to try to bring the battery up to like 25C or so for optimal performance. Also need to be above 0 for charging to avoid damage.
