Abstract
According to overcharge and overdischarge and other undesirable phenomena in the charging and discharging process for all vanadium redox flow battery caused by performance difference of the cells,a simple and efficient equalization control scheme was proposed for all vanadium redox flow battery.Kalman filtering method was used for the online estimation of battery state of charge (SOC),providing a basis for vanadium battery equalization.Supercapacitor was used for the equalization of four batteries based on energy transfer equalization circuit.The energy transfer equalization circuit adjusted switch state and frequency of the MOS to make the SOC value of the cells approach the PSOC value of four batteries.The simulation experiment verifies that the design improves the performance consistency of vanadium battery.关键词
