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. We have a product group covering almost the entire field, from li-ion battery protection board BMS, polymer lithium-ion battery protection board BMS, lithium iron phosphate lifepo4 battery BMS, from 1S 2S digital product battery PCM, to 3S-24S (3S 4S 5S 6S 7S 8S 9S 10S 11S 12S 13S 14S 15S 16S 17S 18S 19S 20S 21S 22S 23S 24S) power battery pack management system BMS, we have a complete process of customization, design, testing, mass production. Software battery protection board, hardware battery protection board, we have a team of more than 30 design engineers, can customize the li-ion battery software protection pcb board with communication interfaces such as CANBUS RS485 SMBUS UART I2C. Our products are widely used in mobile phones, cameras, laptops and other digital electronic products,  power tool battery pack protection circuit pcb boards, electric bicycles, electric scooters, electric motorcycle battery management system BMS, electric vehicle EV battery BMS, etc.

Strong technical strength is the guarantee for the survival of LTW, and advanced production equipment guarantees product quality, with a monthly production capacity of up to 100,000 PCs. LTW BMS enjoys a high reputation in China and abroad for its fine production management and strict quality control management system. "Excellent quality, professional service" is our consistent aim and pursuit. Welcome to Litongwei factory inspection, and is willing to cooperate with you for a long time.

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.
