BorgWarner has announced that it will supply its high-voltage positive temperature coefficient (PTC) cabin heating technology for an unspecified new EV model from a global automaker.
BorgWarner’s technology is designed to provide rapid cabin heating while making the most efficient possible use of energy in order to conserve battery power.
Unlike legacy vehicles, EVs don’t generate a significant source of waste heat that can be used to heat the cabin. BorgWarner’s high-voltage cabin heater relies on ceramic PTC components to warm the air stream coming from the blower. It self-regulates to ensure that high-power heating is available in cold temperatures, when it is needed most. As temperatures rise and heating demand decreases, the energy level is automatically reduced.
The heater offers up to 7 kW of power, provides dual-zone functionality for increased efficiency, and boasts nearly silent operation.
