Battery pack management module and management method

Abstract

The present invention relates to a battery pack management module and a management method. The battery pack management module comprises a first MCU connected with a battery pack and a second MCU connected with a load, the positive electrode of the battery pack is connected with the power input end of the first MCU, the first MCU and the second MCU are connected with each other through a B+ terminal, a B- terminal, a DC terminal and a DP terminal, the B+ terminal and the B- terminal are used for the first MCU to supply power to the second MCU, the DC terminal and the DP terminal are used for data communication between the first MCU and the second MCU, a state detection module is connected between the first MCU and the battery pack, the load is connected with the battery pack through a firstMOS transistor, and the second MCU is connected with a grid electrode of the first MOS transistor to control on-off of the first MOS transistor. The battery pack management module can judge the stateof the battery pack and the matching relationship between the battery pack and the load when the battery pack is used, and can control the use of the battery pack according to the judgment result, sothat the battery pack is matched with the load, and the battery pack is prevented from working with a fault.

Description

technical field [0001] The invention relates to a battery pack management module and a management method. Background technique [0002] At present, there are many kinds of electric tools in China, most of which are middle and low-end products, and generally have the following disadvantages: [0003] 1) The control board and the battery are independent, there is no communication between the two, and the working status of each is unknown. It is easy to make the battery pack work "sickly", affect the battery life, and even cause safety incidents. [0004] 2) Users often use the same battery pack with different tools. Due to the different output characteristics of the battery pack and the power of the power tool, this random matching often causes safety hazards. Contents of the invention [0005] The technical problem to be solved by the present invention is to provide a battery pack management module, which can judge the state of the battery pack and the matching relationshi...
