電気二重層キャパシタの性能・寿命特性と応用技術

摘要

Li-Ion battery (LiB) applications for HEV/EVs have been expanded in the world rapidly. Moreover, super-capacitor (EDLC) applications have been also starting in the World. LiB's on-board capacity for HEV/EVs of commercial vehicles needs roughly 10 times of EDLC's. Why LiB needs so much on board energy capacity for them? From the analysis and simulations for com­mercial HEV/EVs' applications, the EDLC can be operated in 10 times larger charge/discharge power rate than LiB with keeping 10 years life and more. ESS power rate (max.-power of charge/discharge/on-board ESS capacity [kW/kWh]) is the key factor for highly frequent charge/discharge cycles and long life usage.%キャパシタの応用については，蓄電池との性能比較抜きでスタートに立てないが，それぞれの試験法による公称性能の比較のみでの応用検討はかなり困難である．蓄電池のサイクル劣化特性及びキャパシタの劣化特性を考慮した寿命検討が.
