Abstract: A vehicle traction battery cell retainer includes a sidewall defining a plurality of windows each surrounded by a window flange extending therefrom, a top channel extending from the sidewall and terminating in a top flange, and a bottom channel extending from the retainer sidewall, defining a plurality of air bypass windows, and terminating in a bottom flange, the top and bottom flanges arranged for interlocking with an adjacent retainer of the traction battery. A vehicle traction battery assembly includes first and second adjacent battery cell arrays each having associated first and second retainers having a sidewall defining air flow windows and integrated top and bottom channels formed of unitary construction with interlocking flanges to couple the first and second arrays.

Abstract: An electric vehicle battery assembly according to an exemplary aspect of the present disclosure includes, among other things, a battery cell, a rail securing the cell, and a terminal holder in direct contact with the rail.

Abstract: A battery array according to an exemplary aspect of the present disclosure includes, among other things, a rail that supports a battery cell and a tie bracket connected to the rail and configured to limit travel of the rail.

Abstract: A battery stack is provided having lower and upper battery tiers each formed of at least two battery cell arrays. A pair of brackets are provided for connecting the lower arrays along a top surface of the lower tier and connecting the upper arrays to a bottom surface of the upper tier. The lower and upper battery tiers are secured together by the brackets without hardware mounted to an exterior surface of the stack.

Abstract: A vehicle having a traction battery disposed within a battery housing is provided. The battery housing is in selective fluid communication with the cabin of the vehicle. An accessory battery separate and distinct from the traction battery is also provided. A closeable barrier system is electrically connected with the accessory battery and is configured to fluidly isolate the battery housing from the cabin when closed. At least one controller is configured to, in response to a trigger condition, disable the traction battery and increase an output of the accessory battery to close the barrier system to isolate gas in the battery housing from the cabin.
