Should lithium-ion batteries be equalized?
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.
What is a lithium battery equalizer?
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.
What is active equalization of lithium-ion batteries?
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.
How to equalize a high voltage battery pack?
Higher voltage battery packs can be equalised by installing balancers in parallel. The equalization current of different equalizers is different. For example, for the two equalizers of ZHCSolar, the equalization current of the HWB lead-acid battery equalizer is 12A, while the equalization current of the HA series equalizer is 10A.
