CROSS-REFERENCE TO RELATED APPLICATION

This application is based upon and claims priority to Chinese Patent Application No. 201911281051.5 filed on Dec. 13, 2019, the content of which is hereby incorporated by reference in its entirety.

TECHNICAL FIELD

The disclosure relates to the technical field of terminals, and more particularly, to a charging circuit and an electronic device.

BACKGROUND

As functions of intelligent terminals become more and more powerful, power consumption may increase accordingly. Therefore, in order to meet the power consumption demand of the intelligent terminals and extend the endurance of the intelligent terminals, a plurality of batteries have been arranged in some intelligent terminals to increase the battery capacity. However, increasing the number of batteries brings new challenges to the charging mode and charging efficiency.

SUMMARY

According to the first aspect of the embodiments of the disclosure, a charging circuit may include: an interface; a plurality of charging management components connected to the interface in parallel; and a plurality of battery packs, wherein each of the plurality of battery packs includes a battery or a plurality of batteries connected in series with each other, the plurality of battery packs are connected in series with the plurality of charging management components, respectively, and the plurality of battery packs are connected in parallel, wherein the plurality of charging management components are electrically connected with each other to adjust, through signal interaction between the plurality of charging management components, a charging current that is input to each of the battery packs, such that a time period of a maximum charging current for each of the plurality of battery packs is different from a time period of a maximum charging current for another one of the plurality of battery packs.

According to the second aspect of the embodiments of the disclosure, the disclosure provides an electronic device including the charging circuit according to the first aspect above.

The technical solutions provided by the embodiments of the disclosure have the following beneficial effects:

In the embodiments, through signal interaction between a plurality of charging management components, the method can prevent a plurality of battery packs from being charged at high current at the same time, stagger the maximum charging current for the plurality of battery packs, and thus reduce the requirement on the output power of a charging end. Moreover, since the maximum charging currents for the plurality of battery packs are at different time periods, the plurality of battery packs can be prevented from reaching the maximum heating state at the same time, the maximum thermal power consumption can be lowered, and the thermal stack design can be reduced for the electronic device provided with the charging circuit.

It should be understood that the above general description and the subsequent detailed description are only exemplary and explanatory, and shall not limit the disclosure.
