Battery protection pcb, as the name implies, lithium battery protection board is mainly for rechargeable (generally refers to lithium battery) to protect the integrated circuit board. The reason why lithium battery (rechargeable type) needs protection is determined by its own characteristics. Due to the material of lithium battery, it can not be overcharged, over discharged, over current, short circuit and ultra-high temperature charge and discharge. Therefore, lithium battery components always follow a protection board with sampling resistance and a current protector.

Battery protection PCB

The finished lithium battery consists of two parts: the lithium battery cell and the protection plate. The lithium battery cell is mainly composed of positive plate, diaphragm, negative plate and electrolyte; the positive plate, diaphragm and negative plate are wound or stacked, packaged, filled with electrolyte, and then made into battery cells after packaging. Many people do not know the role of the lithium battery protection plate. As the name suggests, the protection plate of lithium battery is to protect lithium battery For the pool, the function of the lithium battery protection board is to protect the battery from discharging, charging and current, as well as output short circuit protection.
