　　Lithium-ion battery pack protection board balance charging principle

　　The number of single-cell lithium-ion battery protection chips is determined according to the number of lithium-ion battery pack batteries, and they are used in series to protect the charging and discharging, over-current, and short-circuit states of the corresponding single-cell lithium-ion battery. At the same time of charging protection, the system realizes balanced charging through the protection chip to control the on-off of the switch device of the shunt discharge branch. The cost of design usage.

　　Lithium-ion battery packs are made up of multiple single lithium-ion batteries connected in series. Due to the differences of the cells, when the terminal voltage rises inconsistently when charging in series, some cells will be overcharged and some cells will be undercharged. All batteries are connected in parallel during equalization charging, and connected in series during normal charging and power consumption. During balanced charging, all batteries connected in parallel have the same voltage, which realizes the forced balancing of each battery.
