Research on the protection circuit of Li-ion battery for power storage

In the protection system for Li-ion battery,temperature protection circuit,equilibrium circuit, self-locking circuit and voltage display circuit are firstly used in protection board due to the defects of domestic protection board.Temperature circuit keeps power MOSFET from damage.Equilibrium circuit can keep consistency of the battery.Self-locking circuit can make the system much more stable while the display circuit can give a visual signal.The experiment results proved the effectiveness of this design.
