ooling strategies are still needed in electric vehicles (EVs), as although the internal combustion engine


(ICE) has been replaced with an electric drivetrain, there are still several other systems that require cooling, such as the high-voltage battery, inverters and traction motors. Depending on whether it’s a battery

EV (BEV) or a hydrogen-powered fuel cell electric vehicle, higher performance electric commercial vehicles need even more cooling capacity and airflow for the size of the braking resistors.


HIGH-VOLTAGE COOLING BorgWarner’s eFan is a high-voltage


cooling fan for electric commercial vehicles, consisting of a large diameter open or ring fan, an electric motor to drive the fan, and an inverter to convert direct current from the battery to the alternating current required to power the motor. Five fan variants provide high-


voltage options for both the low- and high-power vehicle segments. The
