Abstract

The application discloses a battery charging method, a handheld terminal and a readable storage medium. The charging method includes the following steps: in the process of charging the battery according to the first charging system, obtaining the terminal voltage at both ends of the battery; according to the The terminal voltage obtains a corresponding preset pressure difference, wherein the preset pressure difference is the difference between the negative electrode voltage of the battery and the reference voltage of the reference electrode under different terminal voltages; When the pressure difference is set to be less than or equal to a preset value, the battery is controlled to discharge in a preset manner. The present application has the ability to prolong the cycle life of the battery.

Description

technical field [0001] The present application relates to the technical field of power supply, in particular to a battery charging method, a handheld terminal and a readable storage medium. Background technique [0002] At present, during the cycle use of secondary batteries such as lithium-ion batteries, the performance of the battery will attenuate. The reason for the attenuation is that side reactions will occur during the charging process of the battery, and the side reactions will consume effective active materials, resulting in the cycle times of the battery. Decrease, resulting in attenuation of battery life. [0003] The above content is only used to illustrate the technical problem to be solved in this application, and does not mean that the above content is the prior art. Contents of the invention [0004] The main purpose of the present application is to provide a battery power supply method, aiming to solve the problem of attenuation of battery life due to sid...
