Batteriepacks, einschließlich modularer Batteriepacks, halten eine unterschiedliche Anzahl von Batteriemodulen. Wenn die Anzahl geringer ist als die volle Kapazität von Batteriemodulen, wird eine Überbrückungskomponente verwendet, um verschiedene Komponenten des Batteriepacks zu halten. Wenn ein Raum innerhalb eines Batteriepackrahmens nicht durch ein Batteriemodul (oder Batteriemodule) des Batteriepacks belegt ist, kann die Überbrückungskomponente einen Kühlverteiler des Batteriepacks halten. Außerdem kann die Überbrückungskomponente Sammelschienen halten, die teilweise zum Vervollständigen einer Hochspannungsschaltung, die die Batteriemodule einschließt, verwendet werden. Die Überbrückungskomponente kann Clips einschließen, die eingerichtet sind, um die Sammelschienen zu befestigen. Die Überbrückungskomponente kann ferner einen Metalleinsatz einschließen, um zusätzliche strukturelle Steifigkeit bereitzustellen. Ferner kann die Überbrückungskomponente Führungen und Clips einschließen, um die Überbrückungskomponente an einer Komponente (z. B. einem Querträger) des Batteriepacks zu befestigen.
