Lithium battery equalization of the two common equalization methods, lithium battery equalization considerations! Lithium battery pack in the process of charging and discharging the most important link is the equalization link, lithium batteries are required to charge overvoltage, discharge undervoltage, overcurrent, short circuit protection.
Lithium ion batteries are becoming increasingly popular and require a different equalization voltage than lead acid or nickel-cadmium batteries. Battery equalization voltages for lithium ion battery packs should be between 1.8 and 3 volts per cell in order to maintain performance.
According to the voltage characteristic analysis of the lithium-ion battery, when the SOC>80% or the SOC<30%, the voltage consistency is poor. Therefore, it is necessary to turn on the active equalization control so that the battery pack can charge and discharge more power, and improve battery energy utilization.
There are many types of lithium-ion battery equalization circuits, the most common of which is the passive equalization circuit. The active equalization circuit is better than the passive equalization circuit in terms of performance, but it is very complex and expensive .
Battery equalization voltages for lithium ion battery packs should be between 1.8 and 3 volts per cell in order to maintain performance. There are several equalizers on the market for different battery types, they are: Vicron battery balancer, HA Series Lithium ion Balancer and HWB series Lead ACid Battery Balancer:
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.
