BATTERY PACK ASSEMBLY FOR A VEHICLE

A battery pack assembly for a vehicle includes a tray assembly fixed under a floor panel in a vehicle height direction and on which a battery pack-associated component is placed. The tray assembly has a base with a first edge portion and a second edge portion opposite the first edge portion. Each of the first and second edge portions is extended upward relative to the height direction from the base and secured to a frame assembly. A deformation feature is provided at a transition area between the base and the second edge portion. During a crash event the second edge portion is adapted to bend toward the base via the deformation feature allowing a displacement of the base in one of a vehicle front-back direction and a vehicle width direction and also downward in the height direction.
