Couvercle supérieur de la batterie EV
Positionnement du produit :
Le couvercle supérieur de batterie HTD est un bouclier de sécurité structurel spécialement conçu pour les systèmes de batterie haute tension. Utilisant un alliage d'aluminium/acier galvanisé à haute résistance et fabriqué via un estampage intégré et une structure composite multicouche, il atteint un équilibre optimal entre légèreté, intégrité d'étanchéité élevée et protection thermique supérieure, conforme aux normes telles que GB 38031 et IATF 16949.
