Vehicle floor for receiving battery modules

The floor device (100) comprises frame structure formed by the longitudinal beam and cross beam with an upper panel and lower panel to form quasi-hollow cuboids having multiple enclosed allotments. Recesses are provided in both upper and lower panels in area of the cross-beam contact elements for guiding electric lines. The longitudinal- and cross beams form a robust frame, where the cross elements are spaced apart to form the allotment for receiving an energy storage module.
