The invention discloses a temperature control method, device and equipment for a vehicle battery and a storage medium, and relates to the technical field of vehicles, and the method comprises the steps that the first battery temperature of a vehicle, the first environment temperature of the environment where the vehicle is located and a first target curve are obtained, the first target curve is a change curve of dischargeable capacity of a battery of the vehicle along with battery temperature; according to the corresponding relation of the reference environment temperature, the battery temperature and a second reference curve, a second target curve is obtained, and the second target curve is a change curve of energy consumption of the vehicle for heating the battery along with the battery temperature; according to a first target curve and the second target curve, target temperature is determined, and the target temperature is the corresponding temperature when the slope of the first target curve is consistent with that of the second target curve; and controlling the temperature of the battery of the vehicle according to the first battery temperature, the target temperature and a first temperature threshold value. The method can reduce the influence of low temperature on the endurance mileage of the vehicle.
