Why does the 18650 lithium battery pack bring a protective board.48v solar power energy storage power wall

release time:2023-03-28 Hits: Popular:AG11 battery

　　 18650 battery 3.7v 6000mah

　　The battery overcharge function: charge the 18650 lithium -ion battery, and when the battery voltage is charged to the over -charging detection voltage (4.28 ± 0.025 V), protect the circuit work and cut off the charging path, So as to achieve overcharge protection.

　　Battery overlap protection function: When turning on the load discharge, when the battery voltage is reduced to the overlapping voltage (2.3 ± 0.08 V), the protective circuit will move and turn off the circuit to achieve the purpose of the protection.

　　Short -circuit protection function: When the output is short -circuited, the protection circuit will cut off the path after delayed 320 USS to achieve the purpose of short circuit protection. After the external short circuit is lifted, the circuit can automatically restore the output.

　　Overcurrent protection function: When the output current exceeds the setting maximum current value, the protection circuit will move after delaying 10 ms and cut off the path to achieve overcurrent protection. After disconnecting the external load, the circuit can automatically restore the output.

　　Most of the shells of the 18650 lithium -ion battery are made of steel. Under the premise of no protective measures without any protection measures, the pressure inside will increase sharply. Once a certain limit is exceeded, it will be exceeded. Explosion will occur. The short circuit, too high temperature, or twisted by being pressed, or even break may cause the battery to explode.
