The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A battery system comprising:
a plurality of repeating battery subunits arranged in a stack, wherein each battery subunit among the plurality of repeating battery subunits comprises:
a first battery cell,
a heatsink, wherein the heatsink is in contact with each neighboring heatsink in the stack,
a second battery cell, and
a compliant pad, in that order, with the heatsink between and in thermal contact with the first and second battery cells and with the compliant pad abutting the second battery cell and configured to contact the first battery cell of a neighboring battery subunit.
2. The battery system of claim 1, wherein the battery cells are prismatic batteries.
3. The battery system of claim 2, wherein the plurality of repeating battery subunits are arranged in the stack with the compliant pad of one subunit being in contact with the first battery cell of the neighboring battery subunit.
4. The battery system of claim 3, wherein each of the heatsinks are substantially identical to each of the other heatsinks.
5. The battery system of claim 3, further comprising an end subunit wherein the end subunit comprises an end heatsink, an end battery cell, and an end compliant pad stacked in that order and wherein the end compliant pad of the end subunit is in contact with the first battery cell of a neighboring battery subunit.
6. The battery system of claim 3, wherein the battery system further comprises:
a second heatsink positioned at a first end of the stack in thermal contact with the first battery cell of the neighboring battery subunit.
7. The battery system of claim 3, wherein the heatsink of a first battery subunit of the plurality of battery subunits comprises a bottom surface and a side connected to the bottom surface wherein the side is at approximately a right angle to the bottom surface.
8. The battery system of claim 7, wherein the side is formed by an approximately ninety-degree bend in the heatsink.
9. The battery system of claim 7, wherein the side includes two approximately ninety-degree bends in the heatsink and wherein the two bends form an indentation that receives an upper edge of the side of the neighboring heatsink.
10. The battery system of claim 1, wherein the first battery cell of a first subunit
includes a flexible sidewall, and wherein the heatsink of the first subunit includes a tooth structure that extends away from said heatsink and towards the sidewall of the first battery cell, and wherein the tooth structure includes a distal end sufficiently sharp to puncture the flexible sidewall of the first battery cell when the flexible sidewall of the first battery cell is forced up against the tooth structure due to a build up of excess pressure inside the first battery cell.
11. The battery system of claim 1, further comprising a busbar support mounted to the heatsink of a first subunit, and wherein the first battery cell of the first subunit includes a flexible sidewall, and wherein the busbar support includes a tooth structure that extends away from said heatsink and towards the sidewall of the first battery cell, and wherein the tooth structure includes a distal end sufficiently sharp to puncture the flexible sidewall of the first battery cell when the flexible sidewall of the first battery cell is forced up against the tooth structure due to a build up of excess pressure inside the first battery cell.
