The most efficient technique of a battery cooling system is a liquid cooling loop, particularly designed to dissipate heat from the battery packs into the air. The cooling system’s heavyweight affects the EV range as it has to work more to neutralize the payoff load. It also leaves less room for other systems and materials.
EV batteries might experience reduced efficiency and power output in cold climates. A cooling system equipped with heating capabilities can preheat the battery before use, ensuring optimal operation even in low temperatures. Maintaining a stable temperature range ensures a predictable and consistent EV driving range.
Often, the latter solution uses no more than 1kW of cooling and can also be used to heat or cool the cabin. The components that power the EV, such as the HVAC system, motor, inverter, and battery, are optimised by a battery thermal management system (BTMS). The alternative option—one that is used in the majority of EVs—is liquid cooling.
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.
This need for direct cooling arises due to the significant heat generated by the high current flowing into the battery during fast charging. Effective battery cooling measures are employed to efficiently dissipate excess heat, thereby safeguarding both the charging rate and the battery from potential overheating issues.
The adoption of silicon carbide-based electronics, however, with operating temperatures as high as 600 °C (1112°F), has reduced the need for aggressive cooling strategies. However, cooling the electronics for controls like the battery management system (BMS) must be considered.
