Problems solved by technology

However, the life of the battery has always been a big problem that is difficult to solve. The usual lithium-ion battery can only meet about 1000 cycles of charging and discharging.
[0003] How the battery is charged has a great impact on its life. If the battery is accidentally overcharged, the capacity of the battery will be greatly reduced, and there may even be safety issues. The b

Abstract

The invention provides a battery charging method which comprises the following steps of: setting a charging safety voltage, a charging cutoff current and a charging cutoff voltage according to a battery performance parameter; carrying out constant-voltage charging by using the safety voltage until the current of the battery is reduced to the charging cutoff current; and carrying out current-constant charging by using the charging cutoff current until the battery of the battery is increased to the charging cutoff voltage. On the basis that the charging time is not overlong, the battery charging method provided by the invention hardly influences the service life of the battery during charging, and has the advantages of being safe and reliable and high in charging efficiency, and prolonging the service life of the battery.

Description

technical field [0001] The invention belongs to the technical field of battery charging, and in particular relates to a battery charging method. Background technique [0002] With the increasingly prominent problems of environmental pollution, energy crisis, and greenhouse effect, people are paying more and more attention to rechargeable batteries. Whether it is an electric vehicle, a storage power station, or a mobile phone or a laptop, batteries are vital energy storage components. However, the life of the battery has always been a big problem that is difficult to solve. The usual lithium-ion battery can only meet about 1000 cycles of charging and discharging. How to use the battery reasonably so that the battery can cycle more times is a problem worthy of attention. How to discharge the battery is often determined by its working purpose and working conditions, which is generally difficult to control freely, but how to charge the battery can be freely controlled. Differ...
