Intelligent Valves System

Energy efficiency through heat recovery eVTM uses the waste heat from electronic components to control the temperature of the battery, electronics and vehicle interior. This maximizes the efficiency of the heat pump.

Flexible and upgradeable system The components can also be easily integrated into existing series productions. Software updates are possible at any time.

Intelligent coolant utilization An innovative valve system distributes and mixes the coolant optimally. It is only used in the electric heat pump system. The system itself is based on water.

Extended range Conditioning the battery cells increases the service life of the batteries, shortens charging cycles and reduces the total cost of ownership (TCO).
