Abstract
A busbar configured to facilitate electrical connection of multiple battery cells in a manner that further supports functions such as mounting, cell level fusing, layer level fusing, and cooling channels.
Claims13
A busbar battery system comprising:
- a plurality of battery cells, wherein each battery cell has a positive terminal and a negative terminal, wherein said battery cells are physically oriented geometrically in at least two layers of parallel-connected battery cells, wherein said geometrical orientation is configured to form interstitial passages between said plurality of battery cells;
- and
- at least one busbar having a top surface and bottom surface, comprising:
- a unitary body portion having a first cross-sectional material area, a plurality of airway openings, a plurality of fusible link tabs extending down from the body portion, wherein said fusible link tabs each correspond to at least one battery cell, wherein the plurality of fusible link tabs have a second cross-sectional material area, and at least one contact point configured to contact a battery cell, wherein the first cross-sectional material area is larger than the second cross-sectional material area;
- wherein said fusible link tab is configured to exert a spring force against the battery cell to maintain constant contact between at least one battery cell and the fusible link tab;
- and
- wherein said busbar is configured to provide electrical contact between the layers of parallel-connected battery cells,
- wherein a first layer of parallel-connected battery cells is located above a second layer of parallel-connected battery cells,
- wherein said airway openings are configured to facilitate airflow through the interstitial passages between the battery cells.
