Document Type and Number:
WIPO Patent Application WO/2024/001941
Kind Code:
A1
Abstract:
The present application belongs to the technical field of electronic circuits. Disclosed are a double-battery series circuit, a circuit control method and an electronic device. The circuit comprises a battery module, a battery level calculation module, a controller, a battery level balancing module, a first circuit and a second circuit. The battery module comprises a first battery and a second battery which are connected in series. The battery level calculation module is used for collecting the voltage of the first battery and the voltage of the second battery. A first end of the controller is connected to the battery level calculation module, and a second end of the controller is connected to the battery level balancing module, the controller being used for obtaining a battery level balancing control signal according to the voltage of the first battery and the voltage of the second battery. The battery level balancing module is used for controlling the first circuit to work or controlling the second circuit to work according to the battery level balancing control signal. When the first circuit works, the battery module is in a second battery charging state, and when the second circuit works, the battery module is in a first battery charging state.
