Abstract: Electrical energy storage cells, for example, electrochemical double layer capacitor cells, are assembled into a module within an enclosure. The enclosure is built using modular construction so that it can be fitted to a variable number of cells. In exemplary embodiments, the enclosure may be expanded or reduced in size in one, two, or all three dimensions by inserting or removing additional panels. The panels may be interconnected using tongue and groove connectors.

Abstract: The invention relates to a device for accumulation of electrical energy. The device is a substantially cylindrical winding of strips. At least one strip is a strip conductor. The device is defined transversally by a substantially cylindrical lateral face and longitudinally by two opposite end faces. Each of the two opposite end faces contains an edge of the strip conductor. In the device, at least one of the edges of at least one strip conductor contains a plurality of teeth. The teeth are disposed on at least one of the end faces and form at least one set in which they are substantially superimposed in a predetermined direction, approximately perpendicular to a plane tangent to the cylindrical face. The teeth constitute a group of elements of electrical connection to a terminal and in which each element extends itself in continuity with the strip conductor which comprises the element.
