Introduction to the difference between BMS battery management system and button battery cr1620 protection board

What is the difference between BMS battery management system and button battery cr1620 protection board? The main function of button battery cr1620 protection board is to provide energy supply for motors, energy storage equipment and other systems. BMS battery management system has functions such as overcharge, over-discharge, over-temperature, over-current, and short-circuit protection. button battery cr1620 protection board is the charge and discharge protection for series lithium battery packs; BMS lithium battery protection board is very important. What is BMS battery management system? BMS battery system is commonly known as battery nanny or battery butler, mainly for intelligent management and maintenance of each battery unit, to prevent overcharge and over-discharge of the battery, to extend the battery life, and to monitor the battery status.

Functions of BMS battery management system

(1) Measurement of battery terminal voltage

(2) Energy balance between single cells

(3) Measurement of total voltage of battery pack

(4) Measurement of total current of battery pack

(5) SOC calculation: estimation of remaining power of power battery

(6) Dynamic monitoring of working status of power battery pack: prevention of overcharge or over-discharge of battery

(7) Real-time data display

(8) Data recording and analysis: maintaining the reliability and efficiency of the whole battery pack

(9) Communication networking function What is the protection board of lithium iron battery? During the use of lithium battery, under certain conditions, overcharge and over-discharge may cause changes inside the battery, thus affecting the performance and life of the battery. Severe cases may even cause explosion. The function of the protection board is to protect the battery cell. In most cases, power lithium battery must be used together with the protection board to ensure the safety and reliability of the whole system. The main functions of the protection board of lithium iron battery 1. Overcharge protection function. Overcharge protection function means stopping charging when a certain voltage is reached.

2. Over-discharge protection function: when the battery voltage becomes low, the over-discharge protection function stops discharging to the load.

3. Over-current protection function: when the battery voltage becomes low, the over-current protection function stops discharging to the load. The purpose of this function is to protect the battery and MOS tube and ensure the safety of the battery in working state.

4. Short-circuit protection function: it is the core of the protection chip. The difference between BMS battery management system and button battery cr1620 protection board BMS battery management system and button battery cr1620 protection board are both protective umbrellas for lithium batteries, but BMS management system is equivalent to the brain of lithium batteries, which is more intelligent, can be edited, and has battery management software. The protection board is IC+MOS plus some resistors, capacitors and other components, which belongs to hardware protection. Compared with the protection board, BMS battery management system is easier to operate and more convenient. However, whether it can be used normally in low temperature extreme environment remains to be verified. BMS battery management system is of great significance to the protection of electric vehicles, charging station equipment and personnel safety. I believe that in the future, relevant R&D staff will actively explore and continuously research new technologies to promote the upgrade of BMS battery management system and better meet people's life needs. This is the end of the analysis of the differences between the BMS battery management system and the button battery cr1620 protection board.
