【Abstract】 Cell to cell voltage imbalance of ultracapacitors is one of the main reasons for impeding the development of ultracapacitor energy storage application, and voltage equalization can prolong the lifetime of ultracapacitor, increase the amount of stored energy and improve the reliability of the energy storage system. So in many applicatons, voltage equalization technique should be used. A novel voltage equalization circuit was proposed. Based on the operation principle, experiment was made with prototype. The experimental results validate that the above analysis and disclose the proposed voltage equalization circuit is characterized with rapid equalization, simple construct and potential application value.更多还原
