Problems solved by technology

[0006] With the increase of use time, or the increase of storage time after charging, the full charge capacity of all rechargeable batteries will continue to decay, and in the entire life cycle of rechargeable batteries, each charge is charged with a fixed current , which causes the charging rate (ChargingRate) of the rechargeable battery to rise continuously. After the rechargeable battery is used for a period of time, due to its capacity attenuation, the charging rate of the rechargeable battery at this time is much higher than that of the rechargeable battery. The charging rate of the rechargeable battery at the initial stage of use, but if the charging rate is too high, the full charge capacity of the rechargeable battery will rapidly decay and shorten the service life of the rechargeable battery

Embodiment Construction

[0066] In the charging control method and the electronic device according to the embodiment of the present invention, during the charging process, the charging current is determined according to the charging current determination parameters of the rechargeable battery, so that the charging rate of the rechargeable battery during this charging process is within a preset interval, so that Reduce the problem that the full charge capacity of the rechargeable battery will decay rapidly if the charging rate is too high, and prolong the service life of the rechargeable battery.

[0067] In order to better understand the embodiments of the present invention, a number of concepts involved will be described below first.

[0068] The rated capacity is a parameter indicating the maximum capacity that the battery can provide, such as 1600mAH, which is determined after the rechargeable battery is manufactured and is a theoretical parameter.

[0069] Full Charged Capacity (FullChargedCapacit...

Abstract

The invention aims to provide a charge control method and electronic equipment. The charge control method is utilized to control charging of a chargeable battery of the electronic equipment and includes the steps of acquiring a charging current determining parameter of the chargeable battery at beginning of the charging; determining charging current for the charging according to the acquired charging current determining parameter; and charging the chargeable battery by the determined charging current during charging so as to enable charging rate of the chargeable battery within a preset range. By the aid of the charge control method, the service life of the chargeable battery can be prolonged.

Description

technical field [0001] The invention belongs to the field of electronics, and in particular relates to a charging control method and electronic equipment. Background technique [0002] With the development of portable electronic devices, their functions are getting stronger and stronger, so that users can use portable electronic devices in various occasions, [0003] For many portable electronic devices (such as mobile phones, tablet computers, PDAs, etc.), the time that users use rechargeable batteries for power supply is longer than the time for using external power supplies, which puts more pressure on the service life of rechargeable batteries. high demands. [0004] When the existing portable electronic equipment is charging the rechargeable battery, it uses a constant current charging method every time during the entire life cycle of the rechargeable battery, that is, charging with a fixed current. [0005] The inventor found in the process of implementing the embodi...
