Electric High-Voltage Heaters (HVH)
Electric High Voltage Heaters Perfect climate for electric vehicles
The electric High Voltage Heater (HVH) is the ideal heating system for plug-in hybrids and electric vehicles. It converts DC electric power into heat with practically no losses. Webasto‘s innovative technology works with an extremely thin heating layer that is firmly bonded onto the heat exchanger, and a large contact area for heating the coolant. The HVH therefore achieves extremely fast heat-up times, high precision and the highest efficiency. Customers benefit from greater driving ranges with the same battery capacity and optimum climate comfort. In addition, gentle and optimum conditioning of the battery is possible. Furthermore, the system requires only a small installation space and can therefore easily be integrated into vehicles. It offers various control solutions with different functionalities based on the customer‘s requirements. Webasto offers a wide range of accessories for integrating the HVH into vehicles, together with an international support and service network. Good to know: The HVH delivers up to 12 kW heating power and works with voltages up to 880 V, needed by many busses and trucks, as well as LCV and cars. Unique is the active dicharge support function of the HVH 100, 100 C and 120, that reduce the dischage time to milliseconds.
Features: Powerful 5/7/10/12 kW heating performance and wide voltage range up to 880 V independent of coolant temperature Layer technology for extremely fast heat-up Highest efficiency through quick and direct heat transfer Stepless and exact controllability with no inrush currents Reliable safety concept with redundant controls Certified for automotive requirements with ECE-R10 and ECE-R122 type approval CE certified for various segments and applications
