The paper focuses on accepting Hybrid ultra-capacitors as working capacitors from a huge number of unconditioned ones. Hybrid ultra-capacitors of 12 V/2500 F range are evaluated for their performances. Healthy and faulty behavior of these capacitors is analyzed in terms of voltage discharge characteristics. Synthesis of lead carbon hybrid ultra-capacitors of 12 V/2500 F range from electrode to container form is discussed. The steps need to be followed to identify the healthy capacitors from the faulty capacitors are presented. Procedure developed for pre-conditioning of HUCs, performance evaluation and failure analysis results are discussed. From discussion, the condition for acceptance of 12 V/2500 F range Hybrid ultra-capacitor as an energy storage system for solar power applications is formulated.

Abstract


The paper focuses on accepting Hybrid ultra-capacitors as working capacitors from a huge number of unconditioned ones. Hybrid ultra-capacitors of 12 V/2500 F range are evaluated for their performances. Healthy and faulty behavior of these capacitors is analyzed in terms of voltage discharge characteristics. Synthesis of lead carbon hybrid ultra-capacitors of 12 V/2500 F range from electrode to container form is discussed. The steps need to be followed to identify the healthy capacitors from the faulty capacitors are presented. Procedure developed for pre-conditioning of HUCs, performance evaluation and failure analysis results are discussed. From discussion, the condition for acceptance of 12 V/2500 F range Hybrid ultra-capacitor as an energy storage system for solar power applications is formulated.
