  • Publication number: 20060194102
    Abstract: A resistive balance (1) for an energy storage device in the form of a supercapacitor (2). The supercapacitor has two energy storage cells (3, 4). In some embodiments, the balance is disposed intermediate the cells. Balance (1) includes two parallel, spaced apart and co-extensive longitudinal members (5, 6) that respectively extend between ends (7, 8) and ends (9, 10). Two parallel, spaced apart and co-extensive transverse members (11, 12) extend between members (5, 6). While member (11) is attached to members (7, 8) immediately adjacent to ends (7, 9) respectively, member (12) is attached to members (7, 8) adjacent to but spaced inwardly from respective ends (8, 10).

  • Patent number: 7091701
    Abstract: A power supply is for an electrical load in the form of a Notebook computer. The power supply includes first terminals which extend from the computer for releasably electrically connecting with a first energy storage device in the form of a battery during a first interval. A second energy storage device, in the form a second battery, releasably electrically connects with terminals during a second interval spaced apart from the first interval. This allows power to be supplied to the load during those intervals. A capacitive energy storage device supplies power to the load during a third interval that spans the spacing between the first and the second intervals.

  • Patent number: 6998822
    Abstract: A power supply (1) for a pulsed load (2) includes a first energy storage device in the form of a battery (3) which is in parallel with a second energy storage device in the form of a supercapacitor (4). Battery (3) and supercapacitor (4) are respectively modelled as: an ideal battery (7) in series with an internal resistance (8); and an ideal capacitor (9) in series with an equivalent series resistance (ESR) (10). Through use of a supercapacitor (4) having a low ESR with respect to the resistance (8), the power supply (1) facilitates continuity of supply to load (2). That is, during peak demand more of the load current will be supplied by supercapacitor (4) due to the lower ESR. Moreover, during times of lower load current demands the battery recharges the supercapacitor. This reduces the peak current needed to be provided by the battery and thereby improves battery longevity.

  • Publication number: 20050219799
    Abstract: A charge storage device (1) includes a sealed prismatic housing (2). Two opposed folded rectangular aluminium electrodes (3, 4) are disposed within housing (2) and connected to the electrodes. A porous, electronically insulating separator material, e.g. Soluporâ„¢, sheet separator (7) is disposed intermediate electrodes (3, 4) for maintaining those electrodes in a fixed spaced apart configuration. An electrolyte (not shown) is also disposed intermediate the electrodes. Collecting means in the form of a scavenging agent is grafted to separator (7) for sequestering one or more predetermined contaminants from the housing.
