Beschreibung
Zusammenfassung:	A battery box for electric or hybrid motor vehicles, comprising a peripheral frame which has a generally convex polygonal shape, a bottom part and a top cover; the bottom part being joined to a lower surface of the peripheral frame, said peripheral frame comprising at least an aluminum extruded element, bent in a single direction in at least a position along the extrusion longitudinal direction according an angle wherein said bent aluminum extruded element at the said position presents at least two different inner radii of curvatures. L'invention concerne un bac de batterie pour véhicules à moteur électrique ou hybride, comprenant un cadre périphérique qui a une forme polygonale généralement convexe, une partie inférieure et un couvercle supérieur; la partie inférieure étant reliée à une surface inférieure du cadre périphérique, ledit cadre périphérique comprenant au moins un élément extrudé en aluminium, plié dans une seule direction dans au moins une position le long de la direction longitudinale d'extrusion selon un angle, ledit élément extrudé en aluminium plié au niveau de ladite position présentant au moins deux rayons de courbure internes différents.
