Seismic rated battery racking system

A battery rack system for stationary power application comprising a rack assembly configured so as to be seismically rated for UBC Zone IV requirements including a plurality of shelves which are supported by a rack frame such that each shelf along with the rack frame defines a respective cell-receiving area that has a front opening, the rack frame defining a footprint, each shelf having at least one associated cell restraint that is removably connected to the rack assembly and that spans across the front opening to the respective cell-receiving area so as to restrain movement of a cell arranged therein, and at least one channel disposed within the rack frame footprint which extends so as to provide a passage between adjacent cell-receiving areas for accommodating wires used to couple cells stored in the rack system, wherein frame has a pair of opposing front edges and a pair of opposing rear edges, each of the front and rear edges having a crenellated shape with a plurality of crenels and merlons, the crenels defining surfaces to which the cell restraints are attached and the merlons being configured to guide placement of the cell restraints.
