Abstract: A modular cabinet including a plurality of battery modules each which can be withdrawn from the cabinet. The frame has a parallelipipedic-shaped metal framework, including a plinth of rectangular cross-section parallel to the different shelves, roller devices fixed to the base of the plinth to provide movement of the module in the depthwise direction between an inserted position and a withdrawn position, a first vertical front flange extending perpendicularly to the plinth, a second rear flange parallel to the first flange and shelves interposed in the depthwise between the flanges. A closed side plate connects the two flanges and the plinth, and a transverse free space is provided between the batteries and the open side face opposite the side plate. Movement of the module in translation to the withdrawn position enables all the batteries to be fully accessed via the open side face.
