Abstract
A battery system comprises a plurality of battery subunits arranged in a stack, wherein each battery subunit among the plurality of battery subunits comprises a first battery cell, a heatsink, 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.
Claims11
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.
