Investigation of Optimal Test Methods for High Performance EDL Capacitor

抄録

The application of newly developed high performance electric double layer capacitors (EDLCs) is currently expanding to hybrid electric vehicles (HEVs) and other power systems. However, the lack of optimal performance measurement methods that correspond to the increasingly complicated characteristics of new EDLCs prevents easy application engineering. Therefore various experimental and theoretical analyses for new high performance EDLCs were performed. As a result, optimal testing methods for the measurement and evaluation of new EDLCs were successfully established to reveal their capacitance, available energy capacity, internal resistance, charge/discharge energy efficiency, and so on.
