Embodiment Construction

[0059]The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0060] The battery control method provided in the embodiment of the present application may be applied to an electronic device supporting dual batteries, and the electronic device may use the dual battery as a power supply for the electronic device. Optionally, the electronic device can also use the external power supply as the power supply for the electronic device. Of course, if there is an external power supply, the electronic device will give priority to using the external power s...

Abstract

An embodiment of the application discloses a battery control method and an electronic device. By determining the priority of the batteries according to state parameters of each battery and performing charging control or discharge control on each battery according to the determined priority, the priority of the batteries determined based on the dynamic parameters of the batteries may also be dynamically changeable since the state parameters of the batteries are dynamically changeable to realize the dynamic adjustment of the battery priority, thereby avoiding excessive use of one battery while maintaining the state of the long-term high voltage storage of another battery, and extending the service life of the batteries.

Description

technical field [0001] The present application relates to the field of electronic technology, and more specifically, to a battery control method and electronic equipment. Background technique [0002] At present, in an electronic device with two batteries, the charge and discharge control method for the battery is: the main battery of the two batteries is used first, and only when the power of the main battery is empty and there is no external power supply, the two batteries will be used. The secondary battery in the battery. This control method is likely to cause accelerated aging of the main battery due to excessive use, but the capacity of the secondary battery is degraded due to long-term high-voltage storage, making the service life of the two batteries short. Contents of the invention [0003] The purpose of this application is to provide a battery control method and electronic equipment, including the following technical solutions: [0004] A battery control metho...
