리튬 배터리 보호 회로 기판은 어떻게 작동합니까? Posted by batterymanufactory.com
The lithium battery protection circuit board is mainly composed of protection IC (overvoltage protection) and MOS tube (overcurrent protection), and is a device used to protect the safety of lithium battery cells. Lithium batteries are widely used by people for their large discharge current, low internal resistance, long life, and no memory effect. Lithium-ion batteries are strictly prohibited from overcharging, overdischarging, and short-circuiting during use, otherwise it will cause the battery to catch fire and explode. Therefore, when using rechargeable lithium batteries, there will be a protective circuit board to protect the safety of the batteries. Working principle of battery protection circuit board Lithium-ion battery protection circuit boards have different circuits and parameters according to different ICs, voltages, etc. The commonly used protection ICs are 8261, DW01+, CS213, GEM5018, etc. Among them, Seiko's 8261 series have better accuracy and of co...
