DESCRIPTION

[0038]Some embodiments of the invention relate to systems and methods of providing a combination energy storage device that includes a battery system in combination with a capacitor system. In some embodiments, the battery system may have one or more batteries and the capacitor system may have one or more capacitors. The capacitors may be based on various technologies, such as an ultracapacitor, also known as a supercapacitor or electric double-layer capacitor. Examples of ultracapacitors can be found, for example, in U.S. Pat. Nos. 7,791,860; 7,352,558; 7,342,770; 8,072,734; and 7,508,651. Examples of combined battery and ultracapacitor devices can be found, for example, in U.S. Patent Application Publication No. 2012 / 0237799, which is considered part of, and is incorporated by reference in, this disclosure in its entirety. It will be understood that while reference is made herei...

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.
