报告题目：An Efficient Voltage Equalization Algorithm forLow-Power Supercapacitor Applications
报告摘要：Abstract—Voltage equalization of series-connected supercapactors (SCs) is of practical significance for the life and security ofsupercapacitors. In this paper, we proposed an efficient voltageequalization algorithm based on the consensus theory applyingor switched shunting resistor circuit of supercapacitor (SC). In the proposed equilibrium strategy, a proportional-integral (PI) observer is designed to estimate the internal capacitancevoltage of SCs. Then, by comparing the observation value of internal capacitance voltage with those of its neighbors, thevoltages of SCs are balanced before they are fully charged andeven after charging is completed. The experiment results showthat the proposed method has significant superiority and widerapplicability than other exiting methods for equalizing voltage.
