Publication number: 20060194102Abstract: 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).Type: ApplicationFiled: February 13, 2004Publication date: August 31, 2006Inventors: Sarkis Keshishian, Geoffrey Turner, George Paul, Calum Drummond

Patent number: 7091701Abstract: 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.Type: GrantFiled: November 15, 2004Date of Patent: August 15, 2006Assignee: Energy Storage Systems PTY LTDInventors: Geoffrey Alan Turner, Sarkis Keshishian, George Lange Paul

Patent number: 6998822Abstract: 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.Type: GrantFiled: October 21, 2004Date of Patent: February 14, 2006Assignee: Energy Storage Systems PTY LTDInventors: Geoffrey Alan Turner, George Lange Paul, Sarkis Keshishian, Peter John Mahon

Publication number: 20050219799Abstract: 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.Type: ApplicationFiled: June 1, 2005Publication date: October 6, 2005Inventors: George Paul, Rory Pynenburg, Peter Mahon, Sarkis Keshishian
