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.

Highlights

Voltages of up to 880V

The high-voltage range of the HVH 50/70 is between 100 volts and 490 volts and is therefore perfectly suited for most electric cars. The 800 V HVHs round off the product portfolio by being used for both cars and commercially used electric vehicles such as trucks, buses, construction and agricultural machinery. The HVH 100 Compact delivers up to 10 kilowatts of heating power and works with voltages of up to 880 volts, which are required for fast charging. With a heating output of up to 12 kW and a wide voltage range of up to 880 V, the HVH 120 provides powerful and reliable heat in the driver's cab.
