Claim Text:
1. A battery assembly, comprising: a plurality of batteries, each battery of said plurality of batteries comprising a first terminal at a first end portion of said battery and a second terminal at said first end portion of said battery, wherein said plurality of batteries are divided into a plurality of battery groups, wherein each battery group of said plurality of battery groups comprises a subset of said plurality of batteries, wherein said batteries within each subset of said plurality of batteries are electrically connected in parallel, wherein said batteries within each subset of said plurality of batteries are maintained at a different voltage than every other subset of said plurality of batteries, and wherein said battery groups of said plurality of battery groups are electrically connected in series; and a plurality of bus bars positioned proximate to said first end portion of each of said plurality of batteries, wherein said plurality of bus bars are electrically connected to said first and second terminals of each battery of said plurality of batteries; a plurality of heat sink segments, wherein each heat sink segment of said plurality of heat sink segments is electrically isolated from adjacent heat sink segments, wherein each heat sink segment of said plurality of heat sink segments is thermally coupled to one battery group of said plurality of battery groups such that a second end portion of each battery of each battery group is thermally coupled to one heat sink segment of said plurality of heat sink segments, and wherein said second end portion of each battery of said plurality of batteries is distal from said first end portion of each battery of said plurality of batteries; a thermally conductive material layer interposed between said second end portion of each battery of each battery group and a corresponding heat sink segment of said plurality of heat sink segments, wherein said thermally conductive material layer is electrically insulative, and wherein said thermally conductive material layer is in direct contact with said second end portion of each battery of each battery group and said corresponding heat sink segment of said plurality of heat sink segments; at least one coolant conduit thermally coupled to said plurality of heat sink segments, wherein said at least one coolant conduit is electrically isolated from said plurality of heat sink segments.
