HV-PTC (Behr)
Zero Emission vehicles (EV, PHEV,…) engines do not provide enough heat to warm up the passenger cabin. As a new technology to solve this issue, Behr presents high voltage electrical heater (HV-PTC) using PTC (Positive Temperature Coefficient) ceramics and supplied by main vehicle battery (Voltage range 250-400 V). HV-PTC is expected to be replaced from standard heater core in HVAC. The HV-PTC provides up to 5 kW heating power at 350V, instead of 1-1.5 kW at 13V for existing parts. The HV-PTC is insulated to protect the user against electric shock due to high voltage level. In addition, integration with an electronic controller can optimize power consumption and comfort.
