An electric vehicle battery pack with a strike shield affixed to its bottom. The strike shield provides structural support to withstand ground strikes without damaging the batteries within the battery pack. The strike shield is a mixed material sandwich bottom plate structure having a composite top layer, a middle core with one or more hollow members adhesively connected or welded together, or a single integrated structure with elongated stiffeners and/or a base member with elongated channels for stiffness, and a composite bottom layer.

    L'invention concerne un bloc-batterie de véhicule électrique au bas duquel est fixé un bouclier antichoc. Le bouclier antichoc assure un support structurel pour résister aux chocs du sol sans endommager les batteries à l'intérieur du bloc-batterie. Le bouclier antichoc est une structure de plaques intercalées de matériaux mélangés ayant une couche supérieure composite, un noyau central pourvu d'un ou plusieurs organes creux reliés par adhésion ou soudés ensemble, ou une seule structure intégrée pourvue de raidisseurs allongés et/ou d'un organe de base à canaux allongés pour la raideur, et une couche inférieure composite.
