John Miller - Oakridge TN, US

International Classification:

H02J 7/00

US Classification:

307 52

Abstract:

This disclosure provides systems, methods and apparatus for a combined battery/capacitor energy storage device. The device includes a first device terminal, a second device terminal, a battery connected between the first terminal and the second terminal, and a capacitor connected in parallel with the battery. In one aspect, a rectifier is connected between the first terminal and the capacitor, the rectifier configured to allow substantially unidirectional current flow from the first terminal to the capacitor. In another aspect, a switch is between the capacitor and the first terminal. In another aspect, a current limiter extends between the first terminal and the capacitor.

International Classification:

H01M 16/00

US Classification:

429 7, 295921

Abstract:

This disclosure provides systems, methods and apparatus for a battery system. The battery system includes an enclosure, a battery disposed within the enclosure; and at least one ultracapacitor. The ultracapacitor is disposed within the enclosure and coupled to the battery to provide electrical energy via battery terminals. The enclosure conforms to a standard form factor for a battery that comprises one or more conventional storage cells without an ultracapacitor.
