[0024] see figure 1 , the first embodiment of the present invention provides a charging method, comprising:

[0025] Step 101, acquiring the first cycle charging times of the battery.

[0026] Among them, cyclic charging means that the battery completes a complete charging process. Taking a lithium battery as an example, cyclic charging refers to the process from 20% to 100%. Record the number of charge cycles of the battery.

[0027] Step 102: Determine a first charging parameter corresponding to the first charging cycle number according to the pre-established first corresponding relationship between the charging cycle times and the charging parameters.

[0028] Among them, the first corresponding relationship is the corresponding relationship between the number of charging cycles and the charging parameters, that is to say, as the number of charging cycles changes, the charging parameters also change; because the battery capacity decays with the increase in the number of c...

Abstract

The present invention provides a charging method and a mobile terminal. The method comprises a step of obtaining the number of first cycle charging of a battery, a step of determining a first charging parameter corresponding to the number of the first cycle charging according to a pre-established first corresponding relation between the cycle charging number and a charging parameter, and a step of charging the battery according to a first charging parameter. Through establishing the first corresponding relation between the cycle charging number and the charging parameter in advance, the charging parameter is determined, thus the charging parameter is dynamically changed with the number of cycle charging, and the problem that the charging mode of existing electronic equipment mostly is charging with a constant charging parameter and the service life of the battery is shortened is solved.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, and more specifically, to a charging method and a mobile terminal. Background technique [0002] Under normal circumstances, the cycle charge and discharge life of the battery is directly related to the charging current and cut-off voltage. Taking lithium batteries as an example, lithium batteries have the advantages of high energy density, light weight, low self-discharge rate, and no memory effect, and are widely used. In various electronic devices, after 500 cycles of charging and discharging in general lithium batteries, the remaining battery capacity is only 80%. As the number of charging and discharging increases, the power of the battery gradually decreases. However, most of the existing charging methods for electronic devices are to maintain constant charging parameters for charging, and do not adjust charging parameters with the attenuation of battery capacity, such ...
