The active equalization of lithium-ion batteries involves transferring energy from high-voltage cells to low-voltage cells, ensuring consistent voltage levels across the battery pack and maintaining safety. This paper presents a voltage balancing circuit and control method.
When cells have uneven voltages, it can lead to overcharging, undercharging, and reduced battery life. Equalizers prevent these imbalances by transferring charge from high voltage cells to low voltage cells, maintaining an optimal voltage level throughout the pack. There are two primary types of lithium battery equalizers: active and passive.
Although lithium-ion battery energy storage systems are favored for their excellent performance, the large number of batteries connected in series and parallel may lead to inconsistent battery packs, which can cause system problems. Therefore, battery equalization techniques should be employed.
In this paper, the single capacitor method is employed to achieve the energy balance between lithium-ion batteries. By controlling the on-off of the switch, the single battery with higher voltage in the battery pack is charged to the capacitor C, and then the capacitor C charges the battery with lower voltage.
