what is the main function of the lithium battery protection board?

Fake and inferior lithium batteries have serious quality problems. These lithium batteries are very likely to have overcharge and overdischarge problems, which will cause an explosion, and it is also very likely that an internal circuit will short-circuit and cause an explosion. But there is a product that can effectively prevent lithium batteries from overcharging, overdischarging, and short circuiting of internal circuits. It is a protection board for lithium batteries.

Shenzhen Litongwei Electronic Technology Co., Ltd (LTW) established in 2005, A 16-year experienced professional BMS(lithium battery management system) designer & BMS manufacturer in Shenzhen China. More than 8000Sqm Dust-free Workshop, 500+ employees and an excellent R&D Team. We are certified as a National High-Tech enterprise and got ISO9001 and ISO14001 approved. 

LTW’s main products are power battery pack protection circuit board BMS and digital battery protection module PCM.

The main functions of the lithium battery protection board are:

1. The lithium battery protection board can isolate several lithium batteries to avoid the cause of short circuit. The lithium battery protection board has the function of protecting the battery and preventing the battery from overcharging. When the external power supply continues to quickly charge the battery, the lithium battery protection board plays a protective role; when the internal power supply reaches a saturated state, the internal circuit of the lithium battery protection board automatically cuts off the external power supply for fast charging. How to prevent external power from entering the battery? Because of this, the lithium battery guard is to protect the battery from overcharging.

2. When the lithium battery is over-discharged, its internal memory will undergo qualitative changes. At this time, the lithium battery protection board can detect this, and quickly cut off the discharge power to prevent the lithium battery from being completely discharged, so as to ensure the internal current of the lithium battery is stable and avoid Lithium battery is overheated when discharged.

3. The lithium ion battery protection board of the lithium battery must be used in conjunction with it. The main function of the battery protection circuit board is to protect the cells of the rechargeable battery and keep the battery safe and stable during the charging and discharging process, which is very important to the performance of the entire lithium battery circuit system. The role of.
