Analysis of balance principle of lithium battery maintenance board

During the charging process of lithium batteries, each lithium battery is equipped with an equalization circuit. During charging, the equalization circuit of the lithium battery maintenance board controls the voltage of each battery to keep each string of batteries in the same state to ensure the lithium battery's Performance and lifespan. The single-cell lithium battery maintenance chip of the control circuit of the lithium battery maintenance board balance principle can be selected according to the voltage level of the single-cell lithium battery to be maintained and the maintenance delay time. The shunt discharge branch resistance can be completed by a power resistor or a resistor network. Lithium battery maintenance board balance principle maintenance chip subsystem model mainly uses logic operation module, symbolic function module, one-dimensional look-up module, integral module, delay module, switch module, mathematical operation module, etc. to simulate the timing and logic of maintenance actions. Because the simulation environment is different from the actual circuit, do not filter and isolate the strong and weak electricity during the simulation, and the remaining modules are likely to cause the simulation time to be lengthy. The balancing principle of the lithium battery maintenance board is based on the requirements of use. After changing the maintenance chip model and the number of series, the power level of the switching equipment and the energy consumption components in the circuit, the maintenance and equalization of the power lithium battery pack with arbitrary structure and voltage level can be completed. .
