AI Customer ServiceSolar photovoltaic (PV) is considered a very promising technology, and PV-lithium-ion battery energy storage is widely used to obtain smoother power output. In this paper, we propose a battery equalization circuit and control strategy to improve the performance of lithium-ion batteries.
To better quantify the equalization effect, the battery difference and energy utilization rate are defined for evaluation. In order to address the inconsistency problem of series-connected lithium-ion battery groups in practice, a two-level balanced topology based on bidirectional Sepic-Zeta circuit is designed in this article.
After a thorough literature survey, it was found that there are many battery pack equalization strategies developed, but the systematic review and classification are missing. Some studies simply classify the equalization strategies based on the equalization variable, such as voltage, SOC, and capacity.
Active equalization based on capacity during charging and discharging. Capacity-based equalization strategies take C C during charging and C R during discharging as equalization variables to determine whether a battery pack is consistent or not, and then equalize based on capacity.
Due to its strong learning ability, some scholars have applied it to equalization strategy research. C. Lin et al. introduced a novel battery equalization method that shuttles capacity among cells. It calculates the DSM automatically to determine equalization charge under conditions of interference and inconsistency.
It can equalize multiple batteries simultaneously and ensure the normal operation of the batteries. A layered control strategy was then found to solve the optimal equalization current of the equalizer layer by layer. The proposed control method reduces computation time and guarantees that the equalization approach can be employed in practice.
