The power lithium battery protection board is a necessary equipment to enhance the safety of lithium batteries. In many cases, the power lithium battery protection board should have the function of controlling the working conditions of the lithium battery. These working conditions include voltage, current, temperature, etc. Due to the particularity of the use of lithium batteries, the power lithium battery must be matched with the protection board. Use to ensure the safety and reliability of the entire system. Therefore, it is necessary to understand the basic common sense of the power lithium battery protection board. Today, the Chinese Chuangfa will learn with everyone what functions the power lithium battery protection board has?

1. Overcharge voltage protection: prevent the charging voltage from being higher than the upper limit of the battery voltage and cause battery failure and cause safety accidents

2. Overdischarge voltage protection: prevent the battery from deep discharge and avoid Shorten battery life or cause safety accidents

Three, overcurrent protection: limit the current through the protection board and the battery

four, 　short-circuit protection: avoid battery short-circuit causing safety accidents

5. Temperature control switch: To protect the battery pack and the protection board from overheating and cause safety hazards.

The above is the knowledge that the Chinese Chuangfa shared with you today. Finally, the Chinese Chuangfa warmly reminds everyone that you must be cautious when purchasing power batteries, and do not covet temporary cheapness and choose dangerous power lithium battery.
