Cool naturally. Natural cooling is to install a heat dissipation device with high thermal conductivity on the power battery pack, and use the gap between it and the battery cell to directly distribute the heat generated when the battery is charged and discharged into the air. This cooling method has the lowest cost, but the effect is very poor, and it is very easy to overheat the battery, which is basically not used in current electric vehicles.

Air cooling. Air-cooled cooling is to install a fan with a heat sink on the basis of natural cooling to increase the heat dissipation area, and use the fan to speed up the air circulation, and accelerate the heat generated by battery charging and discharging into the air.
three
Liquid cooling. Liquid cooling is to install a liquid cooling device on the power battery pack
