BEV thermal management

In order to optimize energy while increasing the All-Electric Range (AER), a perfect thermal management system is key. Ideal performance of the battery requires a temperature between 20-40℃, no matter the external conditions. Without the heat source of a classical ICE, new sources for heating & cooling need to be optimized. Discover the different modes.
