Abstract

The invention provides a detection device for a BMS (battery pack management system), and problems of low testing efficiency, slow testing speed, and low sensitivity of a conventional detection device are solved. The detection device comprises a bottom layer driving board and a host computer, wherein the bottom layer driving board comprises a simulation device for simulating a BMS battery pack operating circuit and generating over-charge, over-discharge, on-off and balanced initial states and a core processor and a communication module which are used for collecting, processing and analyzing BMS motion signals of the simulation device. The bottom layer driving board is provided with a testing interface, the bottom layer driving board is connected with a protection plate to be tested via the testing interface, the simulation device is connected with the core processor, and the core processor is connected with the host computer via the communication module. The detection device for the BMS (battery pack management system) is advantaged by convenient operation, fast testing speed, and high sensitivity, the detection efficiency and the accuracy of the BMS battery pack management system are improved, and the detection device is applicable to commercial promotion.

Description

technical field [0001] The invention relates to the field of batteries, in particular to a detection device for a BMS battery pack management system. Background technique [0002] With the advancement of the national new energy strategy, high-capacity and high-power lithium battery packs have attracted more and more attention from the market. Early lithium batteries were mainly used in some digital devices with low voltage and power. Now more application requirements are in new energy vehicles, such as electric bicycles, electric motorcycles, electric vehicles and other large-scale batteries that require high voltage and high power output. on durable goods. One of the most important components of this battery pack: BMS (Battery Pack Management System), has not yet formed a standardized mass production scale. There are many specifications and models, and there is no unified testing standard, which leads to the failure of the factory pass rate of BMS. , has caused inconvenie...
