1. A battery pack, comprising: a base plate, a peripheral side wall, and a top cover plate defining an interior region;the peripheral side wall coupled directly to the base plate and extending upwardly from the base plate, the peripheral side wall having first and second side portions disposed at first and second ends, respectively, of the base plate, the second side portion having an aperture extending therethrough;a plurality of battery modules disposed on the base plate between the first and second ends of the base plate along a longitudinal axis of the base plate and within the interior region;a first mounting bracket coupled directly to an inner surface of the first side portion of the peripheral side wall and extending into the interior region toward the second side portion, the inner surface of the first side portion of the peripheral side wall defining a portion of the interior region, a vertical height of the first side portion being greater than a vertical height of the first mounting bracket, the first mounting bracket contacting a first battery module of the plurality of battery modules; anda second mounting bracket having a plate portion, an extension portion extending outwardly from the plate portion, and an elastomeric member disposed on the extension portion; the plate portion of the second mounting bracket being coupled to an outer surface of the second side portion, and the extension portion extending through the aperture in the second side portion and into the interior region; and the elastomeric member contacting a second battery module of the plurality of battery modules within the interior region to fixedly compress the plurality of battery modules between the first mounting bracket and the second mounting bracket along the longitudinal axis; andthe top cover plate being coupled to a top portion of the peripheral side wall. 2. The battery pack of claim 1, wherein each battery module of the plurality of battery modules is box-shaped and is disposed adjacent to at least one other battery module of the plurality of battery modules on the base plate. 3. The battery pack of claim 1, wherein the first mounting bracket has first and second leg portions and a contacting portion, the contacting portion being disposed between the first and second leg portions and being perpendicular to the first and second leg portions, the first and second leg portions being coupled to the first side portion of the peripheral side wall via first and second weld joints, respectively. 4. The battery pack of claim 1, wherein the plate portion of the second mounting bracket has a plurality of apertures extending therethrough configured to receive a plurality of screws therethrough for coupling the plate portion to the outer surface of the second side portion. 5. The battery pack of claim 1, wherein the plate portion of the second mounting bracket has a size greater than a size of the aperture extending through the second side portion such that the plate portion substantially covers the aperture. 6. The battery pack of claim 1, wherein the extension portion of the second mounting bracket has first and second leg portions and a supporting plate portion, the supporting plate portion being disposed between the first and second leg portions and being perpendicular to the first and second leg portions, the first and second leg portions being coupled to the plate portion of the second mounting bracket via first and second weld joints, respectively. 7. The battery pack of claim 1, wherein the first mounting bracket has a contacting portion contacting the first battery module of the plurality of battery modules, the contacting portion being parallel to the plate portion of the second mounting bracket. 8. The battery pack of claim 1, wherein the peripheral side wall is constructed of steel. 9. A method of securing a plurality of battery modules in a battery pack, comprising: providing the battery pack with a base plate, a peripheral side wall, a top cover plate, and first and second mounting brackets; the base plate, the peripheral side wall, and the top cover plate defining an interior region; the peripheral side wall coupled directly to the base plate and extending upwardly from the base plate, the peripheral side wall having first and second side portions disposed at first and second ends, respectively, of the base plate, the second side portion having an aperture extending therethrough, the first mounting bracket coupled directly to an inner surface of the first side portion of the peripheral side wall and extending into the interior region toward the second side portion, the inner surface of the first side portion of the peripheral side wall defining a portion of the interior region, a vertical height of the first side portion being greater than a vertical height of the first mounting bracket, the second mounting bracket having a plate portion, an extension portion extending outwardly from the plate portion, and an elastomeric member disposed on the extension portion;disposing a plurality of battery modules on the base plate between the first and second ends of the base plate along a longitudinal axis of the base plate within the interior region such that a first battery module of the plurality of battery modules contacts the first mounting bracket; andcoupling the second mounting bracket to an outer surface of the second side portion such that the extension portion extends through the aperture in the second side portion and toward the first side portion, the elastomeric member contacts a second battery module of the plurality of battery modules within the interior region to fixedly compress the plurality of battery modules between the first mounting bracket and the second mounting bracket along the longitudinal axis; andcoupling the top cover plate to a top portion of the peripheral side wall. 10. The method of claim 9, wherein coupling the second mounting bracket to an outer surface of the second side portion comprises: disposing a screw through an aperture in the plate portion of the second mounting bracket and an associated aperture extending through the second side portion. 11. The battery pack of claim 1, wherein a width of each of the first and second side portions of the peripheral side wall in a first direction is greater than a width of each of the first and second battery modules of the plurality of battery modules in the first direction, the first direction being perpendicular to the longitudinal axis of the base plate. 12. The battery pack of claim 1, wherein a vertical height of the second side portion is greater than a vertical height of the second mounting bracket. 13. The method of claim 9, wherein a width of each of the first and second side portions of the peripheral side wall in a first direction is greater than a width of each of the first and second battery modules of the plurality of battery modules in the first direction, the first direction being perpendicular to the longitudinal axis of the base plate. 14. The method of claim 9, wherein a vertical height of the second side portion is greater than a vertical height of the second mounting bracket. 15. The method of claim 9, further comprising disposing the second mounting bracket along the longitudinal axis such that the extension portion of the second mounting bracket extends through the aperture in the second side portion toward the first side portion. 16.
