Method for controlling electric heater of HVAC system of vehicle

The present disclosure proposes a method for controlling an electric heater of an HVAC system of a vehicle, the method comprising: turning on the electric heater; determining whether the ambient air temperature of the vehicle is higher than or equal to a threshold ambient air temperature and whether the battery temperature is lower than or equal to a threshold battery temperature; determining whether the battery efficiency is lower than or equal to a threshold efficiency when the ambient air temperature of the vehicle is higher than or equal to a threshold ambient air temperature and the battery temperature is lower than or equal to a threshold battery temperature; and turning off the electric heater when the battery efficiency is lower than or equal to the threshold efficiency, where the electric heater is configured to receive electrical energy from the battery. 本公开提出一种用于控制车辆的HVAC系统的电加热器的方法，该方法包括：开启电加热器；确定车辆的环境空气温度是否高于或等于阈值环境空气温度，以及电池温度是否低于或等于阈值电池温度；当车辆的环境空气温度高于或等于阈值环境空气温度，并且电池温度低于或等于阈值电池温度时，确定电池效率是否低于或等于阈值
