The invention provides a vehicle-mounted battery electric quantity monitoring method and device and related equipment, which relate to the technical field of air conditioners. The battery electric quantity monitoring method comprises the steps of obtaining current state information of a battery, according to the current state information, looking up an electric quantity standard parameter table to obtain the total electric quantity Q1 of the battery, calculating air conditioner electricity consumption Q2 and vehicle-mounted electric appliance electricity consumption Q3, calculating the residual electric quantity Q4 of the battery according to the Q1, the Q2 and the Q3, and when Q4 is smaller than or equal to Q5, controlling the air conditioner to operate in a frequency reduction mode, wherein Q5 is the alarm electric quantity value. Therefore, compared with the total electric quantity obtained through the battery voltage, the influence of virtual electricity is avoided, the obtained total electric quantity is more accurate, when the residual electric quantity Q4 of the battery is low, the air conditioner is controlled to operate in a frequency reduction mode, the air conditioner can be prevented from being excessively used, the residual electric quantity Q4 of the battery is prevented from being too low, the battery of the vehicle at least keeps the electric quantity for starting the vehicle, and the service life of the air conditioner can be prolonged.

    本发明提供一种车载电池电量监测方法、装置及相关设备,涉及空调器技术领域。电池电量监测方法包括:获取电池的当前状态信息;根据当前状态信息,查阅电量标准参数表,获取电池的总电量Q1;计算出空调用电量Q2和车载电器用电量Q3;根据Q1、Q2和Q3,计算出电池剩电量Q4;当Q4≤Q5时,控制空调器降频运行,其中,Q5为报警电量值。这样,相比于通过电池电压获得的总电量,规避了虚电的影响,本发明获得的总电量更加精准,在电池剩电量Q4较低时,控制空调器降频运行,能够避免过度使用空调器,避免电池剩电量Q4过低,使得车辆的电池至少保留有启动车辆的电量,也可以延长空调器的使用时长。
