Air Cooling. Air cooling uses air to cool the battery and exists in the passive and active forms. Passive air cooling uses air from the outdoor or from the cabin to cool or heat the battery. It is usually limited to a few hundred watts of heat dissipation. Active air cooling gets its air intake from an air conditioner, which includes an ...
