Modèle: Battery System
marque: HTD
Lieu d'origine: CHINE
Positionnement du produit :
La barre omnibus interne du bloc de batterie HTD est le composant conducteur principal responsable de la collecte et de la distribution du courant entre les cellules de la batterie au sein d'un module. Utilisant des matériaux composites en aluminium recouvert de cuivre ou du cuivre/aluminium de haute pureté, il atteint un équilibre optimal entre faible résistance, capacité de transport de courant élevée et conception légère grâce à des processus d'estampage, de pliage et d'isolation de précision, garantissant une transmission de courant stable et sûre au sein de la batterie.
