Charge and discharge voltage requirements for lithium iron phosphate batteries

The charging and discharging voltage of lithium iron phosphate battery requires the voltage point of lithium iron phosphate battery (12V40AH), the overdischarge voltage point of lithium iron phosphate battery is 8.0v (according to the overdischarge point of the protection board): in the discharge state, the battery voltage drops to 8. ov, turn off the output of the protection board, and the battery enters an over-discharge state; the over-discharge recovery voltage point of the lithium iron phosphate battery is 9.2v (according to the over-discharge recovery point of the protection board). In the over-discharge state, the battery automatically picks up the 9.2v voltage, disconnects the load, and the battery can restore power to the load; lithium iron phosphate battery Lithium iron phosphate battery charging: 10A standard charging state, the battery voltage reaches 13.41v in the charging state , The battery capacity exceeds 25%; the charging state 50% power voltage point 13.51v: the charging state battery voltage reaches 13.51v, the battery capacity exceeds 50%; the 13.63v voltage point, charging 75%: the battery voltage reaches 13.63v when charging, the battery capacity More than 70%; 100% charging voltage point 14.61v: The battery voltage reaches 14.61v in the charging state, and the battery capacity reaches 100%; the lithium iron phosphate battery discharge: the voltage point corresponds to the 0.5c discharge state of 5% of the electricity 11.90v voltage point: In the discharging state, the battery voltage reaches 11.90v, and the battery capacity remains 5%; in the discharge state, the battery voltage reaches 10%, and the voltage point 12.24v: the battery voltage reaches 12.24v in the discharge state, and the battery capacity remains 10%; the discharge state 25% charge voltage point: the discharge state When the battery voltage reaches 12.55v, the battery capacity is maintained at 25%; the 50% battery voltage point in the discharge state is 12.74v: in the discharge state, the battery voltage reaches 12.74v, and the battery capacity is maintained at 50%; the discharge state is 75% and the charge voltage point: the battery voltage in the discharge state Reached 12.85v, the battery capacity remains 75%; Statement: Some pictures and content of articles published on this site are from the Internet.
