As liquid-based cooling for EV batteries becomes the technology of choice, Peter Donaldson explains the system options now available. A fluid approach. Although there are other options for cooling EV batteries than using a liquid, it is rapidly taking over from forced-air cooling, as energy and power densities increase.
EV Battery Cooling Methods. EV batteries can be cooled using air cooling or liquid cooling. Liquid cooling is the method of choice to meet modern cooling requirements. Let''s go over both methods to understand the difference. Air Cooling. Air cooling uses air to cool the battery and exists in the passive and active forms.
