A battery box, suitable for a skateboard chassis of an electric vehicle (EV), comprises a box (101) and cover (103), the box comprising four side walls vertically connected with a bottom plate. The bottom plate and each side wall have the same multi-layer composite structure comprising: a first, protective aluminium plate 201, relatively located towards an inner side of the box; a second, protective aluminium plate 206, relatively located towards an outer side of the box; and an energy-absorbing buffer sandwich 200 between the first and second protective plates. The buffer sandwich comprises: an octahedral porous core structure inner layer 202, formed by an array of octahedral elements (202A); a spiral vortex structure outer layer 204, formed by an array of spiral vortex elements (204A); and an aluminium partition board 203 arranged between the two structure layers. An outer layer of the second protective plate is compounded with a carbon fibre layer 206. The box cover includes an aluminium plate 802 with an outer carbon fibre resin material layer 801. Two outer sides of the box are fixed with a side anti-collision device (102) comprising a rectangular hollow tube body filled with a honeycomb core body, formed by a close array of honeycomb cells (102A).
