METHOD TO MONITOR SAFE OPERATION OF AN ULTRACAPACITOR

摘要

A container of an electrochemical double-layer capacitor for holding electrodes and electrolyte includes a housing having a cavity and a cap portion coupled to the housing forming a fluid-tight reservoir with the cavity. The container also includes a plurality of terminals incorporated into one or more of the housing or the cap portion, where the plurality of terminals adapted to be electrically coupled to the electrodes, and a pressure-compliant membrane incorporated into one of the housing or the cap portion. A pressure monitoring system that monitors the pressure inside the container includes a displacement measuring device adapted to measure a deflection of the pressure-compliant membrane.
