一种新型超级电容器组电压均衡系统设计
Research on Voltage Balance System for Supercapacitor Stack
To meet the requirements of capacity and voltage in high-power energy storage system, usually multiple supercapacitor are connected in series, for the reason of low voltage of supercapacitor monomer. Because of performance parameter dispersion, the voltages of each monomer in supercapacitor stack unbalance. In this paper, a voltage balance system without energy consumption was designed, based on the burst mode and the charging and discharging characteristics of supercapacitor. The system is composed by signal collection circuits, slave computer, balance switching circuits, and upper industrial personal computer, which can realize the functions of voltage acquisition and switch circuits controlling when tandem supercapacitor charging and discharging. Through the control of switching circuits, the voltages of each supercapacitor monomer tend to accord during charging and discharging, so as to realize the maximum utilization of supercapacitor stack.
