The embodiment of the invention relates to a vehicle battery cooling method and device, electronic equipment and a storage medium. The method comprises the steps that the current corresponding environment temperature, load information and the vehicle speed of a vehicle are determined; based on the environment temperature, determining a battery cooling trigger temperature and a battery cooling target temperature; determining a predicted calorific value of the battery based on the vehicle speed, the load information, and the ambient temperature; determining whether the predicted calorific value meets a battery cooling condition; if the battery cooling condition is met, target refrigeration power of an air conditioner on the vehicle is determined based on the predicted heating value; in response to the fact that the actual temperature of the battery is larger than or equal to the battery cooling trigger temperature in the running process of the vehicle, the air conditioner is controlled to operate according to the target refrigeration power, and the actual temperature of the battery is adjusted to the cooling target temperature. According to the embodiment of the invention, the cooling trigger temperature, the cooling target temperature and the air conditioner refrigeration power can be adaptively adjusted, so that the battery is cooled with relatively low refrigeration power in the vehicle travel, and the energy consumption of the battery is reduced.
