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.
In improving battery inconsistency, Hein et al. provide a capacity-based active equalization method to improve the usable capacity of aging LIBs with minimal equalization effort, but the strategy based on remaining capacity is only applicable when the batteries are in a static state.
According to the equalization control scheme proposed in this study, the equalization system starts to work and equalizes battery packs in series. Bat4 has the smallest initial voltage and its voltage rise rate is relatively fast during the charging process, while the charging speed of other batteries is relatively slow.
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.
