What is the mechanism of charging protection for lithium iron phosphate batteries?

The control strategy of the lithium iron phosphate battery protection screen system 1. Working mode The lithium iron phosphate battery protection panel system is divided into static mode, charging mode and discharging mode according to the battery state. The lithium battery shielding system is powered by external power, and the system start/stop is controlled by external terminals. 2. Protective measures The protective screen system of lithium iron phosphate battery includes single voltage overcharge, total voltage overcharge, overcurrent, high temperature, low temperature, short circuit, etc. The protective measures are as follows: single voltage or total voltage overcharge. When the set protection threshold is exceeded, the charging MOSFET is turned off and charging stops. When the charging overcurrent exceeds the protection threshold 90, the charging MOSFET is turned off and charging is stopped; when the discharge overcurrent exceeds the protection threshold 90, the discharging MOSFET is turned off to stop discharging. The battery is short-circuited. When an instantaneous large current occurs, the charge and discharge MOSFETs are immediately turned off, and the battery stops working. The protection board protects the lithium iron phosphate battery without overloading. In the discharge, short circuit and other problems, the lithium iron phosphate battery protection board is useful and necessary. The protection board circuit can detect the voltage and current of each battery separately, and control the series of batteries. The process of charging and discharging the battery pack.
