With the development of science and technology and the emergence of new energy, high-tech products are becoming more and more popular, such as electric vehicles, electric vehicles, etc., so the battery industry is also booming. Even opportunities are challenges. When it comes to lithium batteries, everyone knows that lithium batteries are rechargeable. How can it be safe to charge and discharge? It is the focus of people's attention. Therefore, the lithium battery needs protection, which is determined by its own characteristics. Because the material of the lithium battery itself determines that it cannot be overcharged, overdischarged, overcurrent, short circuit, and ultra-high temperature charging and discharging, the lithium battery component will always follow Exquisite lithium battery protection board and a piece of current fuse appeared. And what are the components of the lithium battery protection board? Let’s study with everyone today.

Lithium battery protection board usually includes control IC, MOS switch and auxiliary device NTC, ID memory and so on. Among them, the control IC controls the MOS switch to be turned on under all normal conditions, so that the cell can communicate with the external circuit, and when the cell voltage or loop current exceeds the specified value, it immediately controls the MOS switch to turn off to protect the safety of the cell . NTC is the abbreviation of Negative temperature coefficient, which means negative temperature coefficient. When the ambient temperature rises, its resistance decreases. The electrical equipment or charging equipment is used to respond in time and control internal interruptions to stop charging and discharging. ID is the abbreviation of Identification, that is, the meaning of identification. It is divided into two types: one is memory, which is often a single-wire interface memory, which stores information such as battery type and production date; the other is identification resistance. Both can play a role in product traceability and application restrictions.
