Abstract: Provided are a circuit control method, a battery controller, a battery management system, a battery, an electrical apparatus, and a vehicle. The circuit control method includes: acquiring an apparatus wake-up signal; determining whether a power source terminal voltage of a charging circuit of a battery on the apparatus is greater than a first threshold and whether a change rate in a first time length is less than a second threshold, wherein the charging circuit is a circuit connecting the battery on the apparatus and a generator, and the power source terminal voltage is an output voltage of the generator; and issuing a first instruction when the power source terminal voltage of the charging circuit of the battery on the apparatus is greater than the first threshold and the change rate in the first time length is less than the second threshold, so that the charging circuit is turned on.

Abstract: 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.
