Lithium battery protection board, as its name implies, is to protect lithium batteries. Lithium battery Mushroom needs protection because of its characteristics. And what kind of protection function does the lithium battery protection board play on the battery? Today, the Chinese Chuangfa will have a drink together and let us talk about it. The lithium battery protection board has the main protection functions of the lithium battery such as overcharge protection, overdischarge protection, overcurrent protection, short circuit protection and temperature. Let's elaborate on the specific protection functions of the lithium battery protection board.

Overcharge voltage protection: prevent the charging voltage from being higher than the upper limit of the battery voltage, causing the battery to fail and cause safety accidents.

Over-discharge voltage protection: prevent the battery from deep discharge, avoid shortening the battery life or causing safety accidents.　

Overcurrent protection: Limit the current through the protection board and the battery.　　

Short circuit protection: to avoid safety accidents caused by battery short circuit.　　

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