Abstract: The disclosed technology relates to a busbar and thermal cut-off device (TCO) sub-assembly. The sub-assembly may be configured to be connected to a first battery cell and a second battery cell. The sub-assembly may comprise a first busbar configured to electrically connect the first battery cell to the second battery cell when the sub-assembly is connected to the first battery cell and the second battery cell. The sub-assembly may comprise a first TCO connected directly to the first busbar. The sub-assembly may not extend above a top surface of the first battery cell when the sub-assembly is connected to the first battery cell.

Abstract: A flexible busbar comprises a first busbar layer including a first plurality of busbar segments and a first bend between first busbar segments of the first plurality of busbar segments and a second busbar layer coupled to the first busbar layer. The second busbar layer includes a second plurality of busbar segments and a second bend between second busbar segments of the second plurality of busbar segments. The first plurality of busbar segments is substantially colinear with the second plurality of busbar segments and the second bend is substantially parallel with the first bend.

Abstract: A battery pack that comprises a plurality of battery cells and a plurality of plates coupled between adjacent battery cells of the plurality of battery cells. The plates include a plate body and support ledges extending from the plate body. The battery pack further comprises a plurality of support tabs. Each support tab of the plurality of support tabs is positioned between, and abuts against, support ledges of adjacent plates of the plurality of plates. Each support tab of the plurality of support tabs secures adjacent plates of the plurality of plates to each other. The battery pack further comprises a busbar electrically coupling the plurality of battery cells together.
