General lithium battery maintenance board usually includes control IC, MOS switch, resistor, capacitor and auxiliary equipment FUSE, PTC, NTC, ID, memory, etc. Among them, the control IC controls the MOS switch to conduct under all normal conditions to make the cell and the external circuit conduct, and when the cell voltage or loop current exceeds the specified value, it immediately controls the MOS switch to turn off to maintain the cell’s Safety.
When the maintenance board is normal, Vdd is high, Vss and VM are low, DO and CO are high. When any parameter of Vdd, Vss, VM is changed, the level of DO or CO will be Changes.
48V lithium battery can be divided into three yuan lithium battery, lithium iron phosphate battery, lithium titanate battery according to the original data of the battery.
