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.
Abstract:
This disclosure provides systems, methods and apparatus for a combined battery/capacitor energy storage device. The energy storage device includes an energy storage device housing, with a battery housing portion, a capacitor housing portion, and a housing lid. The energy storage device includes a battery disposed within the battery housing portion. The battery includes a first battery terminal extending through a battery lid enclosing the battery housing portion. The energy storage device includes a capacitor disposed within the capacitor housing portion and connected in parallel with the battery. The capacitor includes a first capacitor terminal. The energy storage device includes a first bus bar electrically connecting the first battery terminal and the first capacitor terminal. The energy storage device includes a first external device terminal extending through the energy storage device housing and configured to electrically connect to the first battery terminal and the bus bar.
