Abstract

Claims (34)

1 . An energy storage apparatus comprising:

a battery enclosed within a housing; and

an ultracapacitor directly electrically coupled with the battery via one or more high voltage lines, the ultracapacitor forming a single integrated unit with the battery within the housing, the ultracapacitor having a voltage capacity at least as large as the battery, the ultracapacitor configured to provide energy to the battery via the one or more high voltage lines to charge the battery, the ultracapacitor having a greater power density and a smaller energy density than the battery, wherein the ultracapacitor is configured to removably electrically couple with a 110V or 220V outlet to receive energy originating from a utility grid,

wherein the battery is configured to:

receive energy from the ultracapacitor to charge when a voltage of the battery is less than 360 volts;

resist receiving energy from the ultracapacitor when the voltage of the battery is greater than 370 volts; and

provide energy stored at the battery to an electrical load.

2 . The energy storage apparatus of claim 1 wherein the ultracapacitor is configured to store 400 volts.
