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.
Working principle That equalization system is able to adjust each cell to be equal can avoid the phenomenon which in-pack cell overcharge or over-discharge occurring. For lithium iron phosphate battery series, data acquisition module collects the real-time data of in-pack cells involved terminal voltage, working current and temperature.
A battery-equalization scheme is proposed to improve the inconsistency of series-connected lithium iron phosphate batteries. Considering battery characteristics, the segmented hybrid control strategy based on cell voltage and state of charge (SOC) is proposed in this paper.
Lithium iron phosphate battery voltage change dramatically in the end of the charge and discharge, it means that voltage difference is obvious between in- pack cells even if the battery SOC were similar, the voltage-based equalization algorithm is more advantageous to improve the inconsistency of the battery pack at this stage.
The adopted equalization circuit with bidirectional fly-back transformer is easy to control. The equalization scheme operation principle has been researched and explained. In the simulation validation, not only the voltages but also the SOC of three lithium iron phosphate batteries converged gradually after equalization.
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:
