The invention discloses a motor controller cooling method, a storage medium, a vehicle and a cooling device, and the motor controller cooling method comprises the steps: obtaining the phase current of a motor, and obtaining the temperature of a motor controller; when it is determined that the motor phase current is larger than or equal to the preset current threshold value, virtual heat accumulation calculation is conducted through a water tank method to obtain a heat calculation value, and whether the heat calculation value is larger than or equal to a first heat threshold value or not is judged; judging whether the temperature of the motor controller is greater than or equal to a first preset temperature; and controlling the cooling water pump to start and operate so as to cool the motor controller. According to the motor controller cooling method, the starting times of the water pump are reduced, the service life of the water pump is prolonged, the starting duration ratio of the water pump is reduced, the energy consumption of the electric vehicle is reduced, the driving mileage of the electric vehicle is increased, the starting times of the water pump are reduced, the service life of the water pump is prolonged, the starting duration ratio of the water pump is reduced, and the energy consumption of the electric vehicle is reduced. And the endurance mileage of the electric vehicle is improved.

    本发明公开了一种电机控制器冷却方法、存储介质、车辆及冷却装置,电机控制器冷却方法包括:获取电机相电流,并获取电机控制器的温度;在确定电机相电流大于等于预设电流阈值时,采用水箱法进行虚拟热量累积计算以获得热量计算值,并判断热量计算值是否大于等于第一热量阈值;判断电机控制器的温度是否大于等于第一预设温度;控制冷却水泵开启并运行,以对电机控制器进行冷却。降低了水泵的开启的时长占比,减少了电动车辆的能耗,提高了电动车辆的续航里程,根据本发明的电机控制器冷却方法减少水泵的开启次数,延长了水泵的使用寿命,降低了水泵的开启的时长占比,减少了电动车辆的能耗,提高了电动车辆的续航里程。
