The invention discloses a battery thermal management control method, device and equipment and a storage medium, and relates to the technical field of battery thermal management, and the battery thermal management control method comprises the steps: calculating a battery heating temperature according to a current discharge rate, a current battery temperature and a preset discharge capacity strategy, and obtaining a first battery temperature; performing temperature screening according to the current battery temperature, the first battery temperature, a battery discharge power condition and a temperature power mapping relation to obtain a plurality of second battery temperatures; determining a target battery temperature according to the first battery temperature and the plurality of second battery temperatures; and performing thermal management control on the battery of the target vehicle according to the target battery temperature. The optimal heating target temperature is found by comparing that the heating lifting amount is larger than or equal to the heating consumption amount and meets the vehicle power requirement of a user, and therefore the available discharge capacity of the battery assembly is improved to the maximum degree on the basis that the vehicle power requirement of the user is met.
