It is a high-tech enterprise recognized by the Dongguan Science and Technology Commission. It is a manufacturer specializing in the research and development, production and sales of lithium battery protection boards (BMS). . The principle of lithium battery protection board The reason why lithium battery (rechargeable type) needs protection is determined by its own characteristics. Because the material of the lithium battery itself determines that it cannot be overcharged, overdischarged, overcurrent, short-circuited, and ultra-high temperature charging and discharging, the lithium battery components will always appear with an exquisite protection board and a current fuse. The protection function of lithium battery is usually completed by the protection circuit board and current devices such as PTC. The protection board is composed of electronic circuits, which can accurately monitor the voltage of the cell and the charging and discharging circuit at all times under the environment of -40℃ to +85℃. Current, timely control the on and off of the current loop; PTC prevents severe damage to the battery in high temperature environments. Ordinary lithium battery protection boards usually include control ICs, MOS switches, resistors, capacitors and auxiliary devices FUSE, PTC, NTC, ID, memory, etc. Among them, the control IC controls the MOS switch to turn on under all normal conditions to make the cell and the external circuit conduct, and when the cell voltage or loop current exceeds the specified value, it immediately controls the MOS switch to turn off to protect the cell’s Safety. The lithium battery protection board also has the function of protecting the battery and avoiding battery overcharging. When the external power supply continues to quickly charge the battery, the lithium battery protection board will have a protective effect. When the internal power of the lithium battery reaches the saturation level, the internal circuit of the lithium battery protection board will automatically cut off the external fast charging power supply. So that the external power source cannot enter the battery. This is exactly the principle that the lithium battery protection board protects the battery from overcharging. Precautions for testing the lithium battery protection board 1. When measuring the voltage of each string, the meter pens are placed correctly, and they will short-circuit and smoke when they touch each other. 2. When connecting the protection board, be sure to connect the cable and then plug the protection board, and plug the protection board. Connection may cause burnout of the protection board. The above is the introduction of the lithium battery protection board manufacturer. The type of lithium battery protection board is also designed according to the type of lithium battery or lithium battery pack. Therefore, different types of lithium batteries and protection boards cannot be mixed, and we must correspond to them when using lithium battery protection boards.
