MULTI-TIER TRACTION BATTERY ASSEMBLY WITH ALIGNMENT FEATURE

摘要

A battery assembly includes a lower array including opposing endplates having upwardly protruding pins, and an upper array including opposing endplates having pin bores. The upper array includes a mid-tray defining holes positioned such that the pins are receivable in the holes and the bores when the arrays are properly oriented and such that the mid-tray blocks the pins from being received within the bores when the arrays are positioned in a reverse orientation.

1. A traction battery assembly comprising:
a pair of cell arrays stacked one on top of the other, each array including opposing endplates arranged to contain cells therebetween, each of the endplates defining a same number of locating pin receiving bores, and the arrays being arranged such that the bores of one of the arrays are aligned with the bores of the other of the arrays in bore pairs; and a mid-tray disposed between the arrays and defining a number of pin pass-throughs in registration with the bore pairs, the number of pin pass-throughs being less than the number of bore pairs to orient the arrays relative to one another, and at least one of the endplates of one of the arrays including a locating pin extending away from the endplate through one of the pin pass-throughs and into one of the bores of the other of the arrays.
