1.What is lithium battery mosfet?
During the use of lithium batteries, under certain conditions, overcharging and overdischarging may change the internal battery, thus affecting the performance and life of the battery. Severe cases may even explode. The function of the lithium battery mosfet is to protect the battery. In most cases, the power lithium battery must be used together with the mosfet to ensure the safety and reliability of the whole system.
The main function of lithium battery mosfet
1. Overcharge protection function: It means to stop charging when a certain voltage is reached.
2. Over-discharge protection function: Over-discharge protection function is to stop discharging to the load when the battery voltage becomes low.
3. Over-current protection function: stop discharging the load when consuming high current. The purpose of this function is to protect the battery and MOS tube to ensure the safety of the battery in the working condition.
4. Short-circuit protection function: It is the core of the protection chip.
2.What is BMS battery management system?
BMS battery system, commonly known as battery nanny or battery housekeeper, is mainly used to intelligently manage and maintain each battery cell, prevent battery overcharge and overdischarge, extend battery life and monitor battery status.
Functions of BMS battery management system
1、Measurement of battery terminal voltage
2、Energy balance between single cells
3、Measurement of the total voltage of the battery pack
4、Measurement of total battery pack current
5、SOC calculation: estimating the remaining power of the power battery
6、Dynamic monitoring of the working status of the power battery pack: prevent the battery from overcharging or overdischarging.
7、Real-time data display
8、Data recording and analysis: maintain the reliability and efficiency of the whole battery operation
9、Communication network function.
3.The difference between Li-ion battery mosfet and BMS battery management system
BMS battery management system and Li-ion battery protection Mosfet are both the umbrella of Li-ion battery, but BMS management system is equivalent to the brain of Li-ion battery, more intelligent, editable and equipped with battery management software. The Mosfet is the original IC MOS plus some resistors and capacitors, which is hardware protection. Compared with the Mosfet, BMS battery management system is easier to operate and more convenient.BMS battery management system is important to ensure the safety of electric vehicles, charging station equipment and personnel.
