摘要: Busbars are provided for electrically connecting battery cells within a traction battery pack. An exemplary busbar may include features for locating and positioning a tab terminal of a battery cell. For example, the busbar may include a slot and a bent portion. The tab terminal may be received within the slot such that at least a portion of the tab terminal is positioned on an opposite side of the busbar from a housing of the battery cell. The tab terminal may be secured (e.g., welded) to the bent portion at a section of the busbar that is exposed within the slot.
