摘要： A charge-discharge control circuit, method, device and a storage medium are provided. In some embodiments, the circuit includes: a starting power supply; and a main positive switch unit. In those embodiments, a first terminal of the main positive switch unit is connected to the starting power supply, and a second terminal of the main positive switch unit is connected to a generator of the vehicle and a load of the vehicle. The main positive switch unit is configured to interrupt a current in a first current direction, which is a current direction when the generator charges the starting power supply. The circuit also includes a battery management module configured to detect a voltage of the starting power supply, and control the main positive switch unit to interrupt the current in the first current direction when the voltage of the starting power supply reaches a preset voltage threshold.
