As shown in fig. 4, in one embodiment, the charging circuit includes a first charging input interface 21, a second charging input interface 22, a first power management module 23, a charge pump module 24, and a charge controller 25.

The first power management module 23 is connected to the first charging input interface 21 and the charging controller 25, and is configured to receive a charging voltage of the first charging input interface 21 under the control of the charging controller 25 so as to charge the battery pack;

the charge pump module 24 is connected to the second charge input interface 22 and the charge controller 25, and is configured to receive a charge voltage of the second charge input interface 22 under the control of the charge controller 25 to charge the battery pack.

In this embodiment, by setting two charging interfaces to respectively correspond to two charging output interfaces of the charger, a flexible charging mode can be realized in cooperation with the charger, so as to meet various charging scene requirements. The dual-interface quick charging device has the advantages that the existing bottleneck can be broken through, two batteries can be charged simultaneously, the same charging speed is achieved under the condition that the voltage is safer, the charging speed and the charging safety are improved, and then the user experience is improved.

Optionally, the charge pump module includes a first charge pump unit 241, a second charge pump unit 242, and a third charge pump unit 243.

The first charge pump unit 241 is connected to the second charge input interface to receive the charge voltage of the second charge input interface, and the third charge pump unit 243 is connected to the second charge input interface through the second charge pump unit 242.

Optionally, in the bright screen state, the first power management module may be turned on, and the charging voltage of the first charging input interface is used to provide a charging function for the battery. The first power management module may be implemented by a PMIC (Power Management IC) chip, a power management integrated circuit, which is used to manage power devices in a host system, commonly used for mobile phones and various mobile terminal devices to provide 9V2A charging function.

A charge pump (charge pump), also known as a switched capacitor voltage converter, is a DC-DC converter that uses either a "flying" or "pumping" capacitor (non-inductive or transformer) to store energy. Optionally, in the off-screen state, the charge pump module may be turned on, and the first charge pump unit, the second charge pump unit, and the third charge pump unit provide a charging function to the battery using a charging voltage of the second charging input interface. For example, 20V10A of charging power may be provided in the off-screen state, supporting charging to the battery pack.

Different charging powers are respectively provided by distinguishing the screen-on state and the screen-off state of the terminal, so that the simultaneous charging and discharging conditions of the battery are avoided, the loss of the battery is reduced, and the service life of the battery is prolonged.

For example, the first charge pump and the second charge pump may be connected in parallel to collectively provide a charging voltage to increase instantaneous charging power. For example, the first charge pump and the second charge pump may be connected in series to collectively provide a charging voltage to increase the load carrying capacity.

Alternatively, if desired, a super-charge mode may be provided, with the first power management module and the charge pump module turned on, while the first input interface and the second charge input interface are used to provide a charging function to the battery. For example, in the case where the PMIC, the first charge pump, the second charge pump, and the third charge pump are simultaneously turned on, 218W of charging power may be supplied.
