What are the detailed functions of the lithium battery protection board?

Lithium battery protection boards are mainly used in lithium battery fields such as electric vehicles, model drones, mobile lighting and miner's lamps, power tools, electric bicycles and motorcycles, communication base stations, energy storage equipment, and medical equipment UPS. 1. The most important function of the protection board as a lithium battery customization is to protect the charging and discharging of lithium battery packs in series or in parallel. It can ensure that the voltage value between the individual batteries in the battery pack remains consistent when it is overcharged. Individual batteries are overflowing. In addition, the protection board also tests the lithium battery's over-current, short-circuit, over-temperature, over-voltage, etc., to protect the battery, and protect the battery from over-discharge, over-charge, over-current, and short-circuit protection. The short circuit of the lithium battery has a great risk factor. The short circuit will cause a large current in the battery, and also a large amount of heat, which will seriously damage the service life of the battery. If more serious, the heat will cause the battery to burn and explode. . The protective function of the customized lithium battery protection board is that when a large current occurs, the protection board will be instantly closed, so that the battery is no longer energized and no heat occurs. Overcharge protection: The increased voltage of the lithium battery's charging capacity will also increase. When the battery voltage exceeds the threshold of the overcharge voltage of the protection board, the protection board will cut off the battery and no longer charge; overdischarge protection: lithium The reduced voltage of the battery discharge capacity also decreases. When the battery voltage drops to the threshold of the over-discharge voltage of the protection board, the protection board will be closed and the battery will no longer be discharged. 2. The lithium battery protection board also has the functions of power test, remaining capacity display, battery working status display, communication remote control, etc.; in addition, it can also be equipped with equalization, temperature control and soft switch functions.
