BMS lithium battery protection board and BMS battery management system function analysis

BMS battery protection board, as the name implies, lithium battery protection board is mainly an integrated circuit board for rechargeable (generally referred to as lithium battery) for protection purposes. The battery management system (BMS) is mainly to improve the utilization rate of the battery, guard against overcharge and overdischarge of the battery, extend the service life of the battery, and monitor the status of the battery. With the development of the battery management system, other functions will be added. The main purpose of the power lithium battery protection board is the lithium battery management system for the supply of energy for the motor, energy storage equipment and other systems. The lithium battery protection board is the charge and discharge protection for the series lithium battery pack; purpose: effectively improve the charging effect in the series charging mode, and test the overvoltage, undervoltage, overcurrent, short circuit, and Over-temperature state protects and prolongs battery life. At present, single-cell power lithium batteries have basically met the conditions for popularization, but the existing group technology, group use technology and equipment level are not yet mature. In other words, single power lithium batteries basically deal with safety and life issues, and the key to promoting the development of power lithium batteries is battery pack technology and BMS technology. BMS battery management system function 1. Monitoring function The monitoring function is the most basic function of the battery management system function, which improves the reliable data for the management function. The monitoring content includes the terminal voltage, current, temperature and other parameters of the battery. 2. Protection function Protection functions include overcharge protection, over discharge protection, short circuit protection, reverse connection protection, overload protection, temperature protection, etc. 3. Metering function The metering function is to dynamically report the SOC state of the battery during use. In theory, there is a certain corresponding relationship between the voltage and capacity of the battery. Compare and judge the life of the battery. 4. The control function connects the state of the battery with the external connection through the interface and communication protocol to realize the function of automatic control or remote control.
