Abstract

Sont divulgués un ensemble plaque d'isolation de faisceau de câbles et un module de batterie. L'ensemble plaque d'isolation de faisceau de câbles comprend un corps de plaque d'isolation et une pluralité de connecteurs électriques. Le corps de plaque d'isolation s'étend dans une première direction, le corps de plaque d'isolation comprenant une pluralité de sous-plaques d'isolation, la pluralité de sous-plaques d'isolation étant reliée de manière amovible en séquence dans la première direction, une pluralité de connecteurs électriques étant agencée sur le corps de plaque d'isolation, la pluralité de connecteurs électriques étant configurée pour être connectée électriquement au module de batterie, les deux côtés de chacune des sous-plaques d'isolation dans une seconde direction étant chacun pourvus d'au moins un connecteur électrique, la première direction étant perpendiculaire à la seconde direction. Selon l'ensemble plaque d'isolation de faisceau de câbles et le module de batterie, le coût de l'ensemble plaque d'isolation de faisceau de câbles peut être réduit, et l'efficacité d'assemblage de l'ensemble plaque d'isolation de faisceau de câbles peut être améliorée.
