Method of charging double electric layer electrochemical capacitors

Image Number 14 for United States Patent #8120333.

The present invention is directed to methods for the automatic charging of an electrochemical electrical energy storage device. Charging may be performed until a pre-assigned voltage increment value measured across the terminals of the storage device is reached. Recurrent periods of charging and rest may be employed, with measurements of voltage taken and voltage increment determined after the passage of an assigned quantity of electrical energy. Automatic completion of the charging process is provided for, irrespective of the design features and number of energy storage devices (e.g., capacitors) in a module, the initial state of charge and/or temperature of the storage device, or the value and/or time instability of the charging current.
