본 발명의 실시예에 따른 차량 HVAC시스템의 전기히터 제어방법은, 전기히터가 턴온되는 단계; 차량의 외기온도가 한계 외기온도 이상이고 배터리 온도가 한계 배터리온도 이하인지를 판단하는 단계; 차량의 외기온도가 한계 외기온도 이상이고 배터리 온도가 한계 배터리온도 이하일 때, 배터리 효율이 한계효율 이하인지를 판단하는 단계; 및 상기 배터리 효율이 상기 한계효율 이하일 때 상기 전기히터를 턴오프하는 단계를 포함할 수 있다. 상기 전기히터는 상기 배터리로부터 전기에너지를 공급받도록 구성될 수 있다.

    A method for controlling an electric heater of a vehicular heating, ventilation, and air conditioning (HVAC) system includes turning on the electric heater; determining whether an ambient air temperature of a vehicle is higher than or equal to a threshold ambient air temperature, and a battery temperature is lower than or equal to a threshold battery temperature; determining whether battery efficiency is lower than or equal to threshold efficiency when the ambient air temperature of the vehicle is higher than or equal to the threshold ambient air temperature, and the battery temperature is lower than or equal to the threshold battery temperature; and turning off the electric heater when the battery efficiency is lower than or equal to the threshold efficiency, wherein the electric heater is configured to receive electric energy from the battery.
