Abstract:
1. A method of forming a power source, the method comprising the steps of: forming a first plurality of battery bricks of a first polarity, wherein each battery brick of said first plurality of battery bricks is comprised of a first set of batteries, wherein said step of forming said first plurality of battery bricks further comprises the step of assembling each first set of batteries in a single battery layer and electrically connecting the batteries of said first set of batteries in parallel to one another, wherein each battery brick of said first plurality of battery bricks is comprised of a first positive brick terminal electrically connected to each positive battery terminal of said first set of batteries and a first negative brick terminal electrically connected to each negative terminal of said first set of batteries; forming a forming a second plurality of battery bricks of a second polarity that is reversed from said first polarity, wherein each battery brick of said second plurality of battery bricks is comprised of a second set of batteries, wherein said step of forming said second plurality of battery bricks further comprises the step of assembling each second set of batteries in a single battery layer and electrically connecting the batteries of said second set of batteries in parallel to one another, wherein each battery brick of said second plurality of battery bricks is comprised of a second positive brick terminal electrically connected to each positive battery terminal of said second set of batteries and a second negative brick terminal electrically connected to each negative terminal of said second set of batteries; assembling said first and second pluralities of battery bricks to form a battery pack comprised of a single layer of battery bricks interposed between a first battery pack side and a second battery pack side, wherein said step of assembling said first and second pluralities of battery bricks further comprises the step of mounting each battery brick of said first plurality of battery bricks adjacent to at least one battery brick of said second plurality of battery bricks, wherein said step of assembling said first and second pluralities of battery bricks further comprises the step of mounting each battery brick of said first plurality of battery bricks such that current flows in said first set of batteries in a first direction between said first battery pack side and said second battery pack side, wherein said step of assembling said first and second pluralities of battery bricks further comprises the step of mounting each battery brick of said second plurality of battery bricks such that current flows in said second set of batteries in a second direction between said first battery pack side and said second battery pack side, wherein said first direction is opposite to said second direction, and wherein said first and second directions are substantially perpendicular to said first and second battery pack sides; and electrically interconnecting said first and second pluralities of battery bricks of said battery pack, wherein said step of electrically interconnecting said first and second pluralities of battery bricks further comprises the step of electrically interconnecting each of said first plurality of battery bricks in series with each of said second plurality of battery bricks such that said current flows brick to brick in a substantially circular direction around the periphery of said battery pack relative to each of said first and second battery pack sides, and terminates with a pair of battery pack terminators.
