BorgWarner has agreed a deal with an unnamed “global automotive thermal systems supplier” for high voltage coolant heaters (HVCH) for electric vehicles (EVs).

The heaters would be used on three EV platforms made for an also unnamed “major OEM” and would ensure optimal battery and cabin temperatures.

The company said its 800V HVCH is a compact and lightweight design with fast heating times, ensuring efficient heat transfer and fast charging.

Safety features prevent overheating and will automatically turn the heater off.

The product was claimed to be the first of its kind in North America and the agreement followed a previous deal in which BorgWarner supplied 400V products to the OEM.

Production starts in 2025 at the supplier’s Cadillac, Michigan facility.
