Thermal management systems play a critical role in BEVs. They keep core elements of the powertrain (e-motor, power electronics and battery) at optimum temperature while ensuring the passenger comfort in the cabin. This module features high level integration of the coolant and refrigerant circuit. Being outstandingly effective, it unlocks the full performance of BEVs in different driving conditions, offers comfortable cabin temperatures and achieves higher energy utilization.
