【Abstract】 A model for supercapacitor voltage balancing strategy is introduced, on this basis the authors propose a novel supercapacitor voltage balancing method, namely flying capacitor voltage balancing method, which can efficiently transfer the energy in the capacitor with the highest voltage into that with the lowest voltage, the balancing speed of the proposed method is fast. Firstly, the working principle and process of the proposed method is analyzed in detail, then the rules to choose parameters of flying capacitor is given. Finally, simulation analysis and experiment of the module composed of three supercapacitor connected in series are performed. Results show that the flying capacitor voltage balancing method is practicable and possesses high value for supercapacitor energy storage system.更多还原
