Abstract:
1. A battery system comprising: a plurality of subunits each of which comprises a heatsink and a battery cell having a top end and first and second voltage terminals both of which extend out of the top end of the battery cell, said first and second terminals of each battery cell being symmetrically positioned with respect to a centerline of that battery cell, wherein all of the battery cells among the plurality of subunits are arranged so that their first voltage terminals are aligned along a first row and their second voltage terminals are aligned along a second row; a plurality of identical busbar supports equal in number to the plurality of subunits, each busbar support among the plurality of busbar supports having two slots and being mounted on a corresponding different one of the subunits with each of the first and second terminals of the battery cell for that subunit extending up through a corresponding different one of the two slots; and a plurality of bimetallic busbars, each one supported by a different corresponding subset of the busbar supports and electrically connected directly to either a first or second terminal of each of the battery cells of each of the modules on which those busbar supports are mounted, wherein the battery cells are prismatic battery cells, both the first row and the second rows are situated on the same side of the battery system, and all but one of the heatsinks are identical to each other.
