Problems solved by technology

In order to charge a large-capacity battery in a short period of time, the charging current also increases, and the more serious the electrode deviation from the equilibrium potential is, the more obvious the polarization of the battery is, which shortens the service life of the battery.

Abstract

The invention relates to a battery charging method, a battery charging device and a storage medium. The battery charging method comprises the following steps: determining a charging cut-off current when a battery is in a constant-voltage charging stage; and reducing the charging cut-off current, and charging the battery according to the reduced charging cut-off current. According to the embodiment of the invention, the charging capacity loss caused by polarization reaction increase in the charging cycle process of the battery can be eliminated, the charging capacity of the battery is improved, and the service life of the rechargeable battery is prolonged.

Description

technical field [0001] The present disclosure relates to the technical field of charging, in particular to a battery charging method, device and storage medium. Background technique [0002] Battery polarization is the phenomenon that the potential of the battery deviates from the equilibrium state when the current passes through the battery, and the polarization voltage refers to the potential difference from the equilibrium potential. Due to the existence of the polarization voltage of the battery, the charging capacity of the battery is less than the design capacity of the battery. With the increase in the number of charge and discharge cycles of the battery during use, the battery aging intensifies, the battery polarization gradually increases, and the battery capacity decreases significantly under the same charging conditions. [0003] With the rapid development of science and technology, terminals using batteries have higher and higher demands on battery capacity, and...
