What are the uses of lithium battery protection boards for electric vehicles? Electric vehicle lithium battery protection board (BMS) is one of the core components of electric vehicles. The main function is to protect the battery from charging and discharging and to control the input and output current. More advanced electric vehicles also come with intelligent control, data statistics and transmission. The additional functions of electric vehicles are convenient for consumers to manage electric vehicles more reasonably; the use of lithium-ion battery protection boards for electric vehicles has many protection functions and uses, as follows: ①Overcharge protection, overdischarge protection, overcurrent, Short circuit protection. ②Current protection: It is mainly reflected in the working current and overcurrent to disconnect the switch MOS to protect the battery pack or load. ③Short-circuit protection: Strictly speaking, it is a voltage-comparative type of protection, that is, it is directly turned off or driven by the voltage comparison, and does not undergo unnecessary processing. ④Temperature protection: When the temperature sensor reaches the temperature threshold and the protection delay is reached, the control circuit controls to turn off the charge and discharge MOS tube to stop charging and discharging. ⑤Equalization protection: When a certain string of lithium-ion batteries reaches the equilibrium voltage, the control circuit turns off the charging circuit, and when a certain string exceeds the equilibrium voltage, the control circuit releases the voltage.
