AI Customer ServiceThe equalization methods of lithium-ion batteries can be divided into active methods and passive methods. Passive methods use resistors connected in parallel with the batteries to dissipate excess electricity to balance the battery pack [ 13 ].
The equalization technique is essential to eliminate the influence of more discrete voltage, internal resistance, and capacity to ensure the available capacity and safety of the battery pack. The equalization methods of lithium-ion batteries can be divided into active methods and passive methods.
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.
In pursuit of low-carbon life, renewable energy is widely used, accelerating the development of lithium-ion batteries. Battery equalization is a crucial technology for lithium-ion batteries, and a simple and reliable voltage-equalization control strategy is widely used because the battery terminal voltage is very easy to obtain.
It is expected that innovations such as cloud control methods and hybrid balancing systems equipped with thermal management will become the future direction of lithium-ion equalization technologies. Summary The rapid growth of transportation demand has been enlarged strongly which has promoted electric vehicles powered by lithium-ion batteries.
In the traditional fixed threshold method, when the equalization turn-on threshold is larger, the equilibrium speed of the battery pack will be improved to a certain extent, but the advantages of the equalization strategy designed in this article in improving the inconsistency of the battery pack will be more obvious.
