Addressing the challenges in hybrid (HEVs) and electric vehicles (EVs), BorgWarner’s high-voltage positive temperature coefficient (PTC) cabin heater provides a waste-heat-independent heating solution. The system provides rapid and silent warming of the cabin as well as quick defrosting of the windshield while delivering a smooth air stream for maximum comfort. As part of the heating, ventilation and air conditioning (HVAC) system and controlled through a high-speed Controller Area Network (CAN) interface, the heater is engineered to increase the temperature of the air stream coming from the blower. It features ceramic PTC components that have very low electrical resistance at low temperatures, allowing full current flow and high heat delivery. At high temperatures, the effect is reversed and less heat is released by shutting down the electricity flow due to the increased resistance of the ceramic stones. Additional safety features include an enclosed heater rod for maximum protection against high voltages.
