Thermal management entails regulating heat flows inside the vehicle. The system conveys hot or cold air to where it is needed. For example, the inside of the vehicle should be a pleasant temperature, while certain situations might call for the battery to be cooled or heated. The design of the thermal-management system is growing in importance.
The active cooling and thermal management system helps regulate the temperature of the battery pack at both extremes by cooling it in hot weather, often using liquid coolant that circulates through the battery pack and heating it in cold weather with electric heaters or heat pumps to ensure optimal operating temperatures for the battery.
