Abstract

The invention relates to a system and a method for charging a battery pack. The system comprises a power adapter and a charging management device. The power adapter comprises a power plug and a power line joint. The power plug is used to connect with an AC power supply. The power line joint is used to output direct current. The charging management device comprises a housing, an input end, an output end, and a controller. The input end and the output end are arranged on the housing. The controller is arranged between the input end and the output end. The input end is connected with the power line joint. The output end is used to connect with the battery pack. The controller controls a charging process of the battery pack. The system for charging a battery pack comprises at least two charging management devices. The system and the method for charging a battery pack can charge at least two battery packs, and the number of charging channels can be changed just through changing the number of charging management devices. The charging channels are expanded by the method, and the method is simple and feasible, and has good practicality.

Description

technical field [0001] The invention relates to the technical field of charging, in particular to a battery pack charging system and method. Background technique [0002] With the development of battery technology, people's demand for rechargeable batteries continues to increase, and their performance requirements have also increased significantly. People often refer to batteries that are not assembled into batteries that can be used directly as "battery cells", and several battery cells are assembled and packaged in series and parallel to form a battery pack. Due to the characteristics of high voltage and high current discharge, rechargeable battery packs are widely used in power tools, garden tools and other tools to provide energy for these tools. When charging a battery pack, a charging system formed by a charging management device connected to an adapter is often used to manage the charging state of the battery pack. [0003] Usually, these charging systems have a cer...
