During the charging process, each lithium-ion battery has an equalization circuit. The equalization circuit of the lithium-ion battery protection board controls the voltage of each battery during charging, so that each string of batteries maintains the same state, ensuring the performance and lifespan of the lithium-ion battery.
The single-cell lithium-ion battery protection chip in the equalization principle control circuit of the lithium-ion battery protection board can be selected according to the voltage level and protection delay time of the single lithium-ion battery to be protected. The shunt discharge branch resistor can be implemented using a power resistor or a resistor network.
The lithium-ion battery protection board's equalization principle protection chip subsystem model primarily uses logic operation modules, symbolic function modules, one-dimensional lookup table modules, integration modules, delay modules, switching modules, and mathematical operation modules to simulate the timing and logic of protection actions. Because the simulation environment differs somewhat from the real circuit, filtering and strong/weak current isolation should be avoided during simulation, and unnecessary modules can easily lead to lengthy simulation times.
The equalization principle of lithium-ion battery protection boards can protect and equalize power lithium-ion battery packs of any structure and voltage level by changing the protection chip model and number in series, as well as the power level of switching devices and energy-consuming components in the circuit, according to the application requirements.
