Publication number: 20120068669Abstract: A device and method for harvesting, generating, storing, and delivering energy to a load, particularly for remote or inaccessible applications. The device preferably comprises one or more energy sources, at least one supercapacitor, at least one rechargeable battery, and a controller. The charging of the energy storage devices and the delivery of power to the load is preferably dynamically varied to maximize efficiency. A low power consumption charge pump circuit is preferably employed to collect power from low power energy sources while also enabling the delivery of higher voltage power to the load. The charging voltage is preferably programmable, enabling one device to be used for a wide range of specific applications.Type: ApplicationFiled: July 19, 2011Publication date: March 22, 2012Applicant: TPL, INC.Inventors: John T. Trainor, Patrick Franz Fleig, Charles D.E. Lakeman, Jenniffer Leigh DeGreeff

Patent number: 7864507Abstract: An electric double layer capacitor (EDLC) in a coin or button cell configuration having low equivalent series resistance (ESR). The capacitor comprises mesh or other porous metal that is attached via conducting adhesive to one or both the current collectors. The mesh is embedded into the surface of the adjacent electrode, thereby reducing the interfacial resistance between the electrode and the current collector, thus reducing the ESR of the capacitor.Type: GrantFiled: September 5, 2007Date of Patent: January 4, 2011Assignee: TPL, Inc.Inventors: Patrick Franz Fleig, Charles D. E. Lakeman, Mark Fuge
