description Ultracapacitor is one of most popular device for energy storage system because of it capability that have high charge/discharge efficiency, can operate at high current, have long life cycle and no chemical reaction involve in store and release of energy. Ultracapacitor modelling is important for the electrical system analysis and equipment design. An efficient and high accuracy model can help electrical engineers thoroughly understand ultracapacitor’s characteristics. A commercial ultracapacitor cell is characterized under standard procedures to assess its performance. This project focuses on the analysis and modelling of ultracapacitor cell characteristic.
