> 7.2 kW take a serious cooling system to dissipate.

FWIW, gasoline car radiators can expend upwards of 100kW of heat. After all, internal combustion engines turn most of the energy in gasoline to heat.

Apples and oranges. At the temperature difference between the coolant of combustion engine to the environment heat dissipation is much faster than at the temperature difference between the coolant that is acceptable for batteries to the environment.

And the surface area of a battery pack is orders of magnitude larger than that of an ICE, which greatly helps the thermal transfer.

For a different comparison, 7.2kW is roughly equivalent to 20x 3090 GPUs. The area of a battery pack is (much) larger than the size of 20x GA102 dies. We've got a lot lot of experience extracting large amounts of heat from very tiny spaces. It's an engineering challenge, sure, but it's very well within our means.

Yeah, given that at least some battery packs are already liquid cooled, 7.2kW doesn't seem too bad.
