超级电容器作为一种新型的储能器件，能够在保持传统电容器高功率密度特性的同时获得更大的能量密度。因此，基于超级电容器的电力电子系统将成为越来越多应用的有吸引力的电力解决方案。但在这种情况下，超级电容器通常具有最短的跨度，然后决定系统的寿命。因此，需要对超级电容器进行劣化诊断，以便对电路进行预防性维护。分析了超级电容器的劣化特性，提出了一种在线劣化诊断方法。实验结果验证了分析的正确性。
As a new energy storage device, ultracapacitors are able to attain greater energy densities while still maintaining the characteristic high power density of conventional capacitors. As a result, ultracapacitor based power electronics system will become an attractive power solution to an increasing number of applications. But in this situation, the ultracapacitor usually has the shortest span, and then determines the system lifetime. Therefore, a deterioration diagnosis of the ultracapacitor is needed for preventive maintenance of the circuit. In this paper the deterioration characteristics of ultracapacitor is presented and an online deterioration diagnosis method is proposed. Experimenal results are given to verify the analysis.
