The invention relates to a battery temperature control method and device, computer equipment, a storage medium and a computer program product. The method comprises the steps that the liquid temperature in a pipeline is obtained based on a temperature sensor, and the temperature state of liquid in a water tank is determined according to the liquid temperature; based on the temperature state, the respective states of a water outlet control valve, a four-way valve, a refrigerator, a heater and a water return control valve are adjusted till the temperature sensor obtains that the liquid temperature in the pipeline meets the preset condition, and the refrigerator or the heater is controlled to be closed; the state of the four-way valve is adjusted, so that the liquid with the temperature meeting the preset condition in the pipeline flows to the battery water jacket, and the temperature of the battery water jacket is adjusted. By monitoring the real-time temperature state of the liquid in the water tank and adjusti
