The vehicle of claim 9, wherein the bottom wall and the top wall include increased-thickness portions in areas where the plurality of fasteners are inserted through the battery housing. 12. The vehicle of claim 11, wherein the bottom wall is thicker than the top wall in the increased-thickness portions. 13. The vehicle of claim 8, wherein the second portion of the cross rails is hollow and includes a bottom plate which contacts a surface of the battery housing in the channel. 14. The vehicle of claim 13, wherein the plurality of fasteners extend through the battery housing and the bottom plate into the hollow second portion. 15. The vehicle of claim 14, wherein a bottom wall of the battery housing defines a plurality of grooves which are aligned with the plurality of channels, and wherein heads of the plurality of fasteners are positioned in a respective groove. 16. The vehicle of claim 8, wherein the battery housing comprises: a lower housing which includes a bottom wall which forms a support surface for the plurality of electrical storage devices; andan upper housing which includes a top wall which forms a cover for the plurality of electrical storage devices, wherein the plurality of channels are formed by the upper housing. 17. The vehicle of claim 16, wherein each of the plurality of fasteners is inserted through the bottom wall, the top wall, and a bottom plate of a respective cross rail. 18. The vehicle of claim 17, wherein the bottom wall contacts the top wall in the areas where the plurality of fasteners are inserted. 19. The vehicle of claim 16, wherein the second portion of the cross rails is hollow and includes a bottom plate which contacts a surface of the battery housing in the channel. 20. A method of attaching a battery pack to a vehicle including a frame structure, the frame structure including a plurality of rigid cross rails defining a plurality of bays, the method comprising: positioning the battery pack such that at least a portion of a battery housing is in the plurality of bays and the plurality of cross rails are in a corresponding plurality of channels formed in the battery housing; andattaching the battery housing directly to the plurality of cross rails by inserting a plurality of fasteners through the battery housing and a bottom plate of the cross rails,wherein each of the plurality of cross rails comprises: a first portion which is wider than a respective channel and contacts a top surface of the battery housing adjacent to a respective channel; anda second portion which extends perpendicular to the first portion into the channel and contacts a surface of the battery housing in the channel, the second portion including the bottom plate,wherein the first portion is hollow and includes a flange which extends outwardly and contacts the top surface of the battery housing.
