Powerful, efficient, fast - our high voltage heaters

The electric High Voltage Heater (HVH) is the ideal heating system for battery electric vehicles (BEV) and plug-in hybrids (PHEV). It converts direct current (DC) electric power into heat with practically no losses. The HVH is offered with heat outputs of 5 kilowatt (kW), 7 kW, 10 kW and 12 kW.

Innovative heating layer technology

The HVH heating element, just 0.6 mm thin and 200 cm² in size, consists of a complex layer system and is firmly bonded to the heat exchanger. That is how almost loss-free, rapid conversion of electrical power to heat is achieved.

Benefits of High Voltage Heaters

Constant heat output

The power of the HVH is constant and independent of the coolant temperature or operating voltage.

Powertrain Care

The HVH does not produce inrush current and supports thus a stable system. The battery lifetime is therefore increased thanks to best operating conditions.

Optimized installation

The compact design of the HVH and its low weight allow flexible installation positions in the engine compartment. An intelligent architecture enables easy Plug & Play installation in series production.
