The invention discloses a battery heating control method and device, a storage medium and a vehicle. The method comprises the steps that after the vehicle is powered on, the battery capacity attenuation percentage of the vehicle in the current driving process and the battery electric quantity and the environment temperature in the current driving process are obtained; substituting the obtained battery capacity attenuation percentage, the battery electric quantity and the environment temperature into an objective function of the vehicle cost, and solving a minimum value of the objective function to obtain an optimal value of the battery heating temperature; and adjusting the heating temperature of the battery to enable the adjusted heating temperature of the battery to be equal to the optimal value. According to the method, the optimal value of the battery heating temperature is obtained by solving the minimum value of a vehicle cost objective function constructed based on a driving process power consumption model and a heating battery power consumption model, so that the strategy goal of jointly determining the battery heating temperature by considering the service life of the battery and the vehicle using habit of a user is achieved; and the vehicle use cost consumed in the battery heating link of the vehicle can be effectively reduced.
