Analysis of the working principle of BMS lithium battery management system

The BMS lithium battery system is commonly called a battery nanny or a battery housekeeper. The most important thing is to intelligently manage and maintain each battery unit, guard against overcharge and overdischarge of the battery, extend the service life of the battery, and monitor the status of the lithium battery. BMS lithium battery management system unit includes BMS battery management system, control module, display module, wireless communication module, electrical equipment, battery pack for powering electrical equipment, and collection module for collecting battery information of battery pack . The lithium battery management system BMS determines the status of the entire battery system by testing the status of each single battery in the power lithium-ion battery pack, and performs corresponding control adjustments and strategy executions on the power lithium-ion battery system according to their status to achieve power The lithium battery system and the charge and discharge management of each monomer ensure the safe and stable operation of the power lithium-ion battery system. The topological structure of a typical lithium battery management system is divided into two major parts: the master control module and the slave control module. In detail, it is composed of a central solution unit, a data acquisition module, a data test module, a display unit module, and a control component. Generally, the data information communication between the modules is realized by using the internal CAN bus technology. Based on the functions of each module, BMS can test the voltage, current, temperature and other parameters of the power lithium battery in real time, realize the thermal management, balance management, high voltage and insulation test of the power lithium ion battery, and can calculate the remaining capacity of the power lithium ion battery , Charge and discharge power and SOCu0026SOH status. A good BMS lithium battery management system has a temperature sensor that can monitor the voltage of a single battery pack, and test out the low-performance battery before the battery pack is packaged. This 100% detection guarantees higher output, higher battery capacity and reduces warranty commitments. A good battery management system also records mechanical impact, deep discharge date and information, so you can beware of false warranty applications. An excellent BMS can also test the humidity of lithium battery packs to guard against accidents. The important task of the BMS lithium battery management system is to ensure the design performance of the battery system, which can be analyzed into the following three aspects: 1) safety, protect battery cells or battery packs from damage, and beware of safety accidents; 2) durability, Make the battery work in a reliable and safe area, prolong the service life of the battery; 3) Power, maintain the battery to work in a state that meets the requirements of the vehicle.
