Battery charging method and apparatus

Abstract

The invention discloses a method for charging batteries. The method comprises the following steps: a battery charging module sends an order to a battery monitoring protection module for enquiring whether the battery monitoring protection module is on-line; after receiving the order, the battery monitoring protection module rectifies the communication baud rate and obtains the information of the charging state of a battery; the battery monitoring protection module returns the information of the charging state to the battery charging module; and the battery charging module controls the chargingprocess of the battery according to the information of the charging state. The invention also discloses a device for charging batteries. Through the method and the device for charging batteries disclosed by the invention, the voltage of each battery of a battery pack can be accurately detected to reliably control the charge and the discharge of the battery, and the cost is saved.

Description

technical field [0001] The invention relates to the field of charging control of series battery packs, in particular to a battery charging method and device. Background technique [0002] Portable electronic products are very popular among modern people for their outstanding features such as small size and easy to carry. It can make people's work, study and entertainment free from time and geographical constraints, and significantly improve work efficiency and quality of life. Portable electronic products widely use rechargeable batteries, which have the advantages of repeated charging and large capacity. In particular, lithium batteries are more accepted by people because of their small size, large capacity and long life, and have been increasingly used in various fields. However, if the user uses it improperly or the charger and / or electrical equipment is not intelligent enough, it will shorten the battery life, which in turn will affect the promotion and application of...

AI Technical Summary

Problems solved by technology

[0003] At present, the management application of single-cell lithium batteries is relatively mature, but the management of multi-cell lithium battery packs in series still has some shortcomings, such as: high cost, intelligent degree Insufficient and large control and detection errors, it is urgent to start from the charger and electrical equipment to find a lithium battery pack charging management solution with low price, reliable control, and high precision and intelligence.
