Abstract
A traction battery includes a cell having a terminal defining a surface with a top and at least one sidewall. The traction battery also includes a busbar having an interior defining a top engaging with the top of the terminal, and at least one side surface engaging with the sidewall. One of the side surface and the sidewall includes a projection and the other of the side surface and the sidewall includes a receptacle for receiving the projection.
Claims19
A traction battery comprising:
- a cell including a cylindrical terminal having a top and at least one exterior sidewall;
- and
- a busbar including an interior that receives and circumscribes the cylindrical
- terminal, wherein the exterior sidewall defines a snapping ring projecting outwardly from the sidewall, and a side surface of the interior defines a receptacle for receiving the snapping ring to create a snap fit.

A traction battery assembly comprising:
- a cell including a terminal having a base attached to the cell and a stud distal to the cell, the base having a larger footprint than the stud;
- and
- a busbar defining an interior having an upper portion conforming in shape to the stud and a lower portion conforming in shape to the base, the busbar being received over the terminal with the upper portion receiving the stud and the lower portion receiving the base, wherein one of the upper portion and the stud includes a projection and the other of the upper portion and the stud includes a receptacle for receiving the projection to create a snap fit between the stud and upper portion.
A traction battery assembly comprising:
- an array of cells including a plurality of terminals arranged in a row and extending along a length of the array, each of the terminals being attached to one of the cells and defining a first shape;
- at least one busbar including a pair of terminal portions that each define a second shape conforming to the first shape, wherein one of the terminal portions is received on one of the terminals and the other of the terminal portions is received on an adjacent terminal to electrically connect two of the cells, wherein one of the terminals and the terminal portions further includes a projection and the other of the terminals and the terminal portions further includes a receptacle for receiving the projection to form a snap fit;
- and
- a busbar module (BBM) extending along the length of the row and disposed over the row, the BBM including busbar receiving portions aligned with the terminals, each of the busbar receiving portions defining a third shape conforming to the first and second shapes, wherein the at least one busbar is received within one of the busbar receiving portions.
