1. Lithium battery protection plate
As the name implies, the lithium battery protection board is a circuit board that protects the lithium battery. Its function is to protect the battery from discharging, charging, current, temperature and short circuit. Ensure that the difference between batteries is within a certain range. Improve the charging effect of the battery.

2. Core components of lithium battery protection board
The protection board has two core components: a protection IC, which uses accurate comparators to obtain reliable protection parameters; In addition, the MOSFET string acts as a high-speed switch in the main charging and discharging circuit to perform protection actions.
3. Principle of lithium battery protection plate
The protection function of lithium battery is usually completed by the cooperation of the protection circuit board and PTC. The protection board is composed of electronic circuits. It can accurately monitor the voltage of the battery cell and the current of the charge-discharge circuit at all times under the environment of - 40 ℃ to+85 ℃, and control the on-off of the current circuit immediately; PTC can prevent the battery from severe damage under high temperature environment.
Lithium battery protection board usually includes control IC, MOS switch, resistor, capacitor and auxiliary device NTC, ID memory, etc. The control IC controls the MOS switch on under all normal conditions to make the cell communicate with the external circuit. When the cell voltage or circuit current exceeds the specified value, it immediately (tens of milliseconds) controls the MOS switch off to protect the cell safety. NTC is the abbreviation of Negative temperature coefficient, which means negative temperature coefficient. When the ambient temperature rises, its resistance value decreases, and the electrical equipment or charging equipment responds in time and controls internal interruption to stop charging and discharging.
