Thermal Management Electric Heaters

High Voltage Coolant Heaters (HVCH)

Last update: 29 Aug. 2023

What is a High Voltage Coolant Heater?

Initially designed to heat the coolant in EVs’ standard HVAC module, and improve cabin comfort, High Voltage Coolant Heaters are also used to heat up the battery.

They have now become mandatory for battery pre-heating in cold weather conditions.

Valeo wants to democratize HVCH implementation by offering a flat design to match all demands and also fit into compact A/C Systems.
