Battery energy storage system is the object of this review. Equalization necessity of battery packs connected in series and parallel is analyzed. Equalization topologies, variables and control methods are reviewed. Future research challenges and outlooks of new equalization methods are prospected.
Two four-cell modules for equalizing eight 3.6 V, 18 650 batteries have been built and evaluated. An autonomous battery equalization module, which utilizes an energy circulation technique to equalize the voltage across individual battery cells in a series-connected batteries, is presented. Its structure consists of two power conversion stages.
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.
Equalization method can be extended to almost all battery systems, including nickel and lead-acid batteries, since it is not dependent on battery cells’ characteristics . Equalization topologies for battery packs are categorized into active and passive equalization.
Our standardized container products are engineered for reliability, safety, and easy deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
