The invention provides an electric automobile high-pressure heater protection method and device, electronic equipment and a storage medium, and relates to the technical field of electric automobiles, and the method comprises the steps that after a stop operation instruction for a high-pressure heater is sent in response, whether communication of the high-pressure heater is abnormal or not is detected through the state of an LIN wire; if the high-pressure heater is in the communication abnormal state, monitoring the external temperature of the high-pressure heater in a preset time period, and determining an external temperature difference; and if the external temperature difference exceeds the preset safety threshold value, high-pressure heater fault information is sent to an electric control system, and the whole vehicle is controlled to be powered off through the electric control system so as to carry out dry burning fault protection on the high-pressure heater. According to the method and the device, the danger of over-temperature and even fire caused by continuous work when heating is not needed due to the fact that the heater cannot respond to an instruction of closing the heater after communication loss is avoided, and the use safety of the electric vehicle heater is improved.

    本申请提供了一种电动汽车高压加热器保护方法、装置、电子设备和存储介质,涉及电动汽车技术领域,该方法包括:响应针对高压加热器的停止运行指令发出后,通过LIN线状态检测高压加热器是否通讯异常;如果高压加热器为通讯异常状态,则对高压加热器在预设时段内的外部温度进行监测,确定外部温度差;如果外部温度差超过预设安全阈值,向电控系统发送高压加热器故障信息,通过电控系统控制整车断电,以进行高压加热器的干烧故障保护。本申请避免由于加热器通讯丢失后无法响应关闭加热器的指令,导致在无需加热时继续工作从而引发的过温甚至起火的危险,提升了电动汽车加热器的使用安全。
