Abstract
A charging circuit can include: a first input terminal for receiving an input signal; a first switching circuit coupled between the first input terminal and a first battery; a second switching circuit coupled between the first input terminal and a second battery; a bidirectional buck-boost circuit coupled between the first input terminal and a main battery; where when an external power supply is connected, the input signal respectively charges the first battery and the second battery through the first and second switching circuits, and charges the main battery through the bidirectional buck-boost circuit; and where when an external power supply is not connected, the main battery charges the first battery through the bidirectional buck-boost circuit and the first switching circuit, and charges the second battery through the bidirectional buck-boost circuit and the second switching circuit.
