Abstract
The application of Super Capacitors (SCs) as an energy storage system covers a broad range of applications from transportation to stationary applications. There are also a variety of applications in which SC are used as an energy damper like in a textile industry which SC can be used to store the reciprocating energy from the weaving-loom machines for the next forward movement in order to improve the efficiency of the system. In this research, a commercial SC has been studied for lifetime expectation in such kind of application. An Extended Kalman Filter (EKF) electro-lifetime model is developed and validated. The result shows that in this alternative current application, the lifetime is much less than the nominal conditions due to the low frequency effect. An error of less than 2% proves the accuracy of the proposed model. With this ageing model, the lifetime can be examined, and the best utilization profile can be designed to ensure the SC safety and lifetime extension
