To be able to operate electric and hybrid vehicles at a particularly high level of efficiency, it is necessary to maintain an optimal temperature range for the electric motor, the power electronics and the battery. A perfectly designed thermal management system is required to achieve this.
The entire cooling system is divided into several circuits: driven by the coolant pump, the coolant flows to special actuators, which regulate the amount of cooling each of the components has. Valves are electrically controlled and open or close parts of the circuit as required or connect several circuits together.
In electrified vehicles, an optimum heat balance can only be achieved by using thermal management products and intelligent valve control and the vehicle then moves with maximum efficiency.
