Improved cooling efficiency, and reduced energy consumption. Coolant flows directly around individual battery modules instead of the entire pack, enabling precise temperature control. More efficient heat removal, reduced weight and complexity.
However, as the energy density of battery packs increases, the cooling efficiency of air cooling is insufficient to meet the heat dissipation requirements [11]. PCM utilizes the physical property of phase change, absorbing and releasing heat during the solid–liquid phase transition, which expands the limitations of active heating/cooling [13].
The traction battery can be used as a thermal buffer accumulator in the powertrain, amongst other things. A homogeneous temperature distribution within the battery must be taken into consideration when designing the battery cooling system. Disproportionately high hot zones, or hot sports, on individual cells in the battery pack can lead to a

Rapid, reliable detection and a quick response from the cooling system are therefore essential. A typical cylindrical cell in the 21700 format, for example, has a power dissipation of around 5% when operating at low load, but can exceed that figure considerably at higher loads, according to an expert in battery and cooling systems. A 100 kWh
