Based on this model, a supercapacitor voltage balancing method for Rubber Tyrad Gantry Crane (RTG)energy-saving system, namely active voltage balancing method, was proposed, which had fast and high efficient balancing speed. Its working principle was analyzed in detail, and the simulation analysis for the supercapacitor module in series was performed after the voltage balancing circuit was designed. The results show that this method for balancing voltages can avoid over-voltage of each cell and possess practicable and high value for supercapacitor RTG energy-saving system.
