The invention discloses a battery heating system, a battery heating method, equipment and a storage medium, and belongs to the technical field of vehicles. A control device in the system obtains a target temperature required to be reached by a battery when a vehicle is started; based on the target temperature, a first wake-up signal is sent to a vehicle control unit; after the vehicle control unit is awakened, a second awakening signal is sent to the battery management system; after the battery management system is awakened, a first closing signal is sent to the cathode relay, and a second closing signal is sent to the heating relay; wherein the first closing signal and the second closing signal are respectively used for controlling the cathode relay and the heating relay to enter a closed state; the cathode relay and the heating relay entering the closed state and the thermistor form a current path; and after the thermistor is electrified, the battery is heated to a target temperature. According to the system, when the vehicle is started, the battery can reach a proper discharge temperature, so that the discharge temperature of the battery in a low-temperature environment is increased.
