Abstract
L’invention porte sur les bacs de batteries pour les véhicules électriques ou hybrides. Les fonds des bacs batteries sont fait avec une tôle mince en acier dont le module d’élasticité est supérieur à 220 GPa afin d’en optimiser l’épaisseur tout en assurant une résistance à l’intrusion. Figure d'abrégé : Fig. 1
