1. A battery pack, comprising: a tray;a cover mounted to said tray; anda beam system including a first beam attached to said tray and a second beam attached to said cover,wherein said first beam includes a first flared portion and said second beam includes a second flared portion that nests with said first flared portion. 2. The battery pack as recited in claim 1, wherein said first beam and said second beam are top hat shaped. 3. The battery pack as recited in claim 1, wherein at least one of said first beam and said second beam is movable between a first position and a second position in response to a loading event in which a force is applied to either said tray or said cover. 4. The battery pack as recited in claim 3, wherein said first beam and said second beam abut one another in said second position. 5. The battery pack as recited in claim 1, wherein said first flared portion is received over a protrusion of said tray. 6. The battery pack as recited in claim 1, wherein at least one of said first beam and said second beam includes an area of varying thickness. 7. The battery pack as recited in claim 1, wherein said first beam and said second beam are metallic structures. 8. The battery pack as recited in claim 1, comprising at least one cutout established between said first beam and said second beam. 9. The battery pack as recited in claim 8, comprising a battery pack component routed through said at least one cutout. 10. The battery pack as recited in claim 1, comprising a second beam system spaced from said beam system. 11. The battery pack as recited in claim 1, wherein said first beam is attached to a bottom surface of said tray and protrudes toward said second beam, and said second beam is attached to an internal surface of said cover and protrudes toward said first beam. 12. A battery pack, comprising: an enclosure; a battery assembly housed inside said enclosure; and a beam system including a first beam attached to a first portion of said enclosure and a second beam attached to a second portion of said enclosure, wherein said first beam includes a first flared portion and said second beam includes a second flared portion that nests with said first flared portion, and wherein prior to a loading event said first beam and said second beam are spaced apart, and subsequent to the loading event said first beam and said second beam abut against one another. 13. The battery pack as recited in claim 12, wherein said first beam and said second beam extend along a transverse axis, said transverse axis extending transverse to a longitudinal axis of said battery assembly. 14. The battery pack as recited in claim 12, wherein said first portion of said enclosure is a tray and said second portion is a cover. 15. The battery pack as recited in claim 12, comprising a second beam system disposed between said first portion and said second portion of said enclosure. 16. The battery pack as recited in claim 12, wherein said beam system is disposed between said battery assembly and an electronic module housed inside said enclosure. 17. The battery pack as recited in claim 12, wherein said second beam is disposed at the same axial location as said first beam such that said second beam is directly above said first beam. 18. The battery pack as recited in claim 12, comprising at least one cutout between said first beam and said second beam. 19. The battery pack as recited in claim 18, comprising a battery pack component routed through said at least one cutout. 20. A method, comprising: positioning a beam system within a battery pack enclosure, wherein the beam system includes a first beam attached to a tray of the battery pack enclosure, a second beam attached to a cover of the battery pack enclosure, and a cutout established between the first beam and the second beam, said first beam including a first flared portion and said second beam including a second flared portion that nests with said first flared portion; and positioning a component within the cutout, the component including a bus bar module, a sense lead, a high voltage wire, or a coolant line, wherein prior to a loading event in which a force is applied to either the tray or the cover, the first beam and said second beam are spaced apart, and subsequent to the loading event, the first beam and the second beam abut one another without contacting the component.
