HVH: The electrifying choice for EV heating

The electric High Voltage Heater (HVH) is the ideal heating system for electric vehicles and plug-in hybrids. The HVH converts direct current (DC) electric power into heat with practically no losses.
The HVH achieves extremely fast heat-up times, high precision and the highest efficiency. 

High Voltage Heater for electric vehicles

Our strength

Power

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

Safety

Safety is key. We have integrated multilevelsafety measures in the design of the hardware and software as well as in the mechanism of the HVH. 

Precision

The heating layer of the HVH can be regulated quickly and precisely. It absorbs short-term power peaks and converts them directly into heat.
