No, not at all. Every modern EV already has an actively cooled battery. In almost all cases it’s liquid cooled, and in some older EVs it’s air cooled.
The only mass produced EV without an actively cooled battery was the first generation Nissan Leaf, which is the reason why they have notoriously bad battery degradation (which left a lasting impact on the reputation of EV battery reliability).
Many EVs can even use the heat generated by the battery to help the heat pump heat up the cars interior during winter. Hyundai were the first with that technology in the 2020 facelift of the Ioniq Electric and Kona Electric, and Tesla implemented the same tech 3 years later with their “octovalve”
