The present application discloses a method, apparatus, system, device and storage medium for controlling a charge and discharge circuit. The charge and discharge circuit includes an M-phase motor winding, where M is a positive integer. The method includes: controlling the charge and discharge circuit to start charge and discharge; acquiring a first current value and second current values, where the first current value is a current value flowing through a neutral line of the M-phase motor winding, and the second current value is a current value flowing through a single winding; determining whether a current charge and discharge state is normal according to the first current value and the second current values; and if not, controlling the charge and discharge power to be reduced. With the method for controlling according to the present application, it is determined whether the current charge and discharge state is normal according to the current value flowing through the neutral line of the M-phase motor winding and the current values flowing through the windings. If it is determined to be abnormal, the charge and discharge power is controlled to be reduced, thereby effectively reducing the safety hazards caused by abnormal current values and improving the safety of the charge and discharge circuit.
