They cool the battery pack alone or alongside another cooling system when needed. Apart from adding air cooling holes into the battery pack, coolant tubes are integrated into the battery pack. A heat transfer medium such as water or other anti-freezing mixtures can be used as the coolant to absorb heat from the battery pack.
The battery packs are located on top of a cold plate which consists of cooling channels to direct the cooling liquid flow below the battery packs. The heat absorbed by the cooling liquid is transported to the Heating-Cooling Unit. The Heating-Cooling Unit consists of three branches to switch operating modes to cool and heat the battery.
When the ambient air temperature is low, for example during the winter, or the vehicle is moving and hence, the airflow rate is high, the battery pack can be sufficiently cooled without the aid of another cooling system. The air cooling holes act as a passive cooling system.
A liquid or air cooling system must manage this elevated heat without compromising safety or performance. Fast charging also demands cooling systems capable of rapidly dissipating generated heat to prevent overheating, a factor that could undermine battery longevity and safety.
