DEVICES AND METHODS FOR CONNECTING BATTERY CELLS

摘要

A vehicle traction battery assembly includes a bus bar insulator having a recess configured to receive a bus bar and an opposite side covering the bus bar and defining a welding slot sized to permit a welding beam to weld the bus bar to two adjacent battery cells and to inhibit human contact with the bus bar through the welding slot. A method for assembling a vehicle traction battery having battery cells includes positioning bus bars within corresponding openings of a bus bar insulator that covers one side of each bus bar and has welding slots with a welding slot for each of the battery cells and welding the bus bars to the associated battery cells through the welding slots.

主权项

1. A vehicle traction battery assembly, comprising:
a bus bar insulator having a first side with a recess configured to receive a bus bar and an opposite side covering the bus bar and defining at least one welding slot sized to permit a welding beam to weld the bus bar to at least two adjacent battery cells and to inhibit human contact with the bus bar through the at least one welding slot.
