Patent ID: 7575828

Claim:
A combination comprising a module for a battery system supporting batteries during seismic stress comprising a pair of side panels, each panel formed of material such as steel shaped to define a generally rectangular face and top and bottom flanges extending generally perpendicularly to the face along top and bottom edges thereof and side flanges formed integrally with the face and top and bottom flanges; a base plate having means for mounting the module to a support surface having a generally U-shaped channel formed integrally along the front and rear edges of the base plate; a rear panel extending between and nested in the side panels and secured thereto and the base plate; at least one pair of front and rear support channels extending between the side panels; a shelf for batteries supported on the base plate and support channels; a support channel extending vertically between the top and bottom flanges; means for securing modules stacked one on top of another along the top and bottom flanges; a pair of spaced base assemblies defining a gap there between to accommodate a fork lift to move the base assemblies and modules from one location to another during an installation process; said base assemblies being of box like structure having confronting opening sides for access to the module bolt holes and anchor bolt holes from the gap between the base assemblies; and each base assembly comprising an inner channel of J-shaped cross section having a short leg and a wider bottom leg and an outer channel comprising a lower channel member and an upper channel member each of L-shaped cross section and wherein the inner channel nests in the outer channel and is secured thereto by spot welds along the elongated slot between the upper and lower channels and a plurality of spaced gussets and a pattern of bolt holes in the channel members for anchoring the base assemblies and modules to a support surface and which are accessible through the gap between the base assemblies.
