High Voltage Coolant Heaters (HVCH)
Last update: 17 Mar. 2025What is a High Voltage Coolant Heater?
High Voltage Coolant heaters (HVCH) were initially developed to heat glycol in the HVAC modules of electric vehicles, ensuring optimal comfort in the cabin. Their role has expanded with battery preheating, an essential functionality in cold climates to preserve the performance and range of electric vehicles.
Valeo wants to democratize the implementation of HVCH by offering a flat design, allowing their integration into compact air conditioning systems and thus meeting all requirements.
