Li-ion battery protection plate and Li-ion battery management system difference

With the rapid development of society, our lithium battery protection board and lithium battery BMS management system are also developing rapidly, so do you know the detailed analysis of the lithium battery protection board and lithium battery BMS management system? Next, let the editor lead everyone to understand the relevant knowledge in detail.

The lithium battery protection board can play a role in the charge and discharge protection of the series and parallel battery packs, and can detect the overvoltage, overcurrent, overtemperature, undervoltage, and short circuit status of each single cell in the battery pack, prolonging the battery life and avoiding The battery is damaged by over-discharge. Lithium battery protection board is an indispensable part of lithium battery.

Battery Management System (Battery Management System) is abbreviated as BMS, which has the function of measuring battery voltage, and also includes battery protection function, battery equalization function, battery reserve function, energy calculation function, network communication function, etc. The battery management system can prevent the battery from over-discharge, over-charge, over-temperature and other abnormal conditions.

The lithium battery protection board also has a balanced protection function, and there are two ways of energy consumption and energy transfer. Energy-consumption equalization refers to the use of resistors to consume a certain battery with high power or voltage among multiple strings of batteries. Energy-consuming balance is divided into equalization during charging, voltage fixed-point equalization, and static automatic equalization.

Lithium battery protection board is mainly an integrated circuit board that plays a protective role for rechargeable (generally referred to as lithium battery). The reason why the lithium battery needs protection is determined by its own characteristics. Since the material of the lithium battery itself determines that it cannot be overcharged, overdischarged, overcurrent, short circuited, and ultra-high temperature charging and discharging, the lithium battery components of the lithium battery will always appear with a delicate protection board and a current fuse.

Battery Management System (Battery Management System) is abbreviated as BMS, which has the function of measuring battery voltage, and also includes battery protection function, battery equalization function, battery reserve function, energy calculation function, network communication function, etc. The battery management system can prevent the battery from over-discharge, over-charge, over-temperature and other abnormal conditions. Since lithium batteries may damage battery performance and even cause explosion hazard under severe overcharge and overdischarge conditions, the existence of the battery management system is to monitor, protect, and manage lithium batteries in a balanced manner, thereby improving the working efficiency of lithium batteries.

The lithium battery management system BMS determines the status of the entire battery system by detecting the status of each single battery in the power battery pack, and performs corresponding control adjustments and strategy implementations on the power battery system according to their status, and realizes the control of the power lithium battery system and The charge and discharge management of each monomer ensures the safe and stable operation of the power battery system.

Lithium battery protection board is composed of IC, MOS tube, resistor and capacitor components, and is an important component of lithium battery. The battery management system can be edited and comes with battery management software, which is relatively smarter, equivalent to the brain of a lithium battery, and plays a role of control.

The lithium battery protection board plays an important role in the 3C lithium battery and power battery fields, and the battery management system is applied in the power battery field. The lithium battery protection board can isolate several lithium batteries and avoid the cause of short circuit in the circuit.

The above is a detailed analysis of the relevant knowledge of the lithium battery protection board and the lithium battery BMS management system. It is necessary for everyone to continue to accumulate experience in practice, so as to design better products and better develop for our society.
