METHOD FOR CHARGING AND DISCHARGING A DOUBLE LAYER ELECTRICAL CAPACITOR

WIPO Patent Application WO/2003/081618

A2

The invention relates to electrical engineering, more specifically to electrochemical double-layer capacitors and can be used for developing electrical energy storage devices which are used for: - emergency power supply during the operation in a continuous or compensating charge mode; - continuous power supply when intermittently or continuously functioning power sources are used; - devices for the reliable starting of internal combustion engines. The inventive method consists in pre-measuring an electrolyte temperature in a capacitor, determining, according said temperature, the maximum working voltage of charging at which a leakage current and a power capacity are optimum, the discharge of the capacitor being carried out at a charge temperature. Said invention is characterised in that the capacitor is charged to a voltage at which the leakage current ranges from 10^-6 to 10^-5 A/F, the working temperature being selected such that it is lower than 0 °C.
