WO2003081618A2 - Method for charging and discharging a double layer electrical capacitor - Google Patents

Abstract

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.

The invention is also charac- terized also by charging the voltage, in addition to the loss of voltage, which is 10 ^"6 -10 ^" , which takes less than 10 ° C.

The optimum voltage is selected by experience with allowance for the capacitance of the leak and the leakage path. According to the invention, the voltage compensates for voltage, the magnitude of the voltage determines the empirical loss for each voltage and the voltage for The leakage current is selected taking into account the capacitance of the condenser. Reducing the operating temperature will increase the operating voltage of the compensator. In this case, the voltage of the alkaline electrolyte is decomposed due to an increase in the output voltage of oxygen and oxygen to the electric elec- trode 4 sat. In this case, the other voltage, depending on the temperature, can reach values from 1.5 to 2 Β.

An increase in the operating voltage makes it possible to substantially increase the specific energy of the condensate. With this, the capacitance and internal resistance of the capacitor do not change significantly.
