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) electrical power into heat with low conversion losses.
The HVH supports rapid heat generation, precise control and efficient energy use. 

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 voltage range of up to 880 V, the HVH 120 helps maintain comfortable temperatures in the driver's cab.

Our production

From Neubrandenburg, Webasto supplies around 150 automotive plants worldwide with heating systems. After the headquarters in Stockdorf, the plant has grown to become the Webasto Group's largest location in Germany with around 700 colleagues. Seven different heater ranges are manufactured there. This includes water and air heaters for all vehicle segments such as cars and trucks, as well as High Voltage Heater for hybrid and electric vehicles. Above that a research and compentence center for electromobility is located in Neubrandenburg. 

Since 2019, a further production facility for the HVH has been located at the Wuhan site. The production line for the High Voltage Heaters covers a production area of ​approx. 1,000 m².
