What is a lithium battery protection board?

With the use of batteries, people pay more and more attention to the lithium battery protection board. It is the core component of every lithium battery. The battery is inseparable from it. Why is it so important? Because the lithium battery protection board has important protection functions for the battery such as overcharge, overdischarge, overcurrent, and short circuit. So what is a lithium battery protection board? This is very important to everyone, because we use it everywhere and all the time (such as mobile phones, electric cars, etc.), so today, the Chinese Chuangfa will take a look at what is a lithium battery protection board?

The lithium battery protection board is the charge and discharge protection for the series connection of lithium battery packs. When fully charged, it can ensure that the voltage difference between the individual cells is less than the set value (generally ±20mV), realize the equal charge of the individual cells of the battery pack, and effectively improve the charging effect in the series charging mode. At the same time, it detects the overvoltage, undervoltage, overcurrent, short circuit, and overtemperature status of each single battery in the battery pack to protect and extend the battery life. Under-voltage protection prevents each single cell battery from being damaged due to over-discharge during discharge. The finished lithium battery consists of two main parts, lithium battery core and protective plate. The lithium battery core is mainly composed of positive plate, diaphragm, negative plate and electrolyte; positive plate, diaphragm, negative plate are wound or laminated, packaged, and filled with electrolyte , After packaging, it is made into batteries. Many people don’t know the role of lithium battery protection board. The important thing is said three times. Lithium battery protection board is used to protect lithium batteries, as the name suggests. The role of lithium battery protection board is to protect the battery. However, there is no discharge, no charge, no current, and there is output short-circuit protection.
