Moreover, it only provides the most stable and effective protection to prevent accidents when there are extreme problems with the battery. It should not be operated at ordinary times. Of course, monitoring is necessary, just like the fuses or safety switches in our home appliances. With the development of society, battery protection boards are put into use in large quantities.

[0003] Prior art such as the utility model with publication number CN216214187U discloses a multifunctional battery protection board, which includes a board body, an alarm light connected to the right upper end of the board body, a clamping wiring structure connected to the left upper end of the board body, the clamping wiring structure including a wiring seat and a transmission plate, a connecting groove is provided in the middle of one side of the wiring seat, a sealing sleeve is provided on the inner side of the end of the connecting groove, and a power connection sheet is provided at the bottom of the connecting groove. The transmission plate is movably arranged above the connecting groove, and the wire connected to the lithium battery is arranged in the connecting groove. The sealing sleeve at the end of the connecting groove plays a role of sealing and dustproof. Then, by rotating the transmission bolt, the transmission bolt rotating in situ drives the internal thread linkage block restricted by the sliding of the slide groove to move axially downward, and the internal thread linkage block drives the transmission plate, and the transmission plate drives the arc surface clamping plate to elastically clamp the wire, effectively preventing the wire shell from being worn. At the same time, the transmission plate will also drive the connecting rod, and the connecting rod drives the sealing pressing plate to squeeze the sealing sleeve to further improve the sealing degree.
