Les barres conductrices (70A à 70C) sont configurées avec des corps de connexion métalliques (71A à 71C) qui relient les bornes (20, 21) de chaque module de batteries (100), et des éléments isolants (73A à 73C) qui couvrent les corps de connexion métalliques (71A à 71C). La barre conductrice longue (70A), dont la longueur est au moins le double de la hauteur du module de batteries (100), est supportée par des pièces d'extension (74B, 74C) qui s'étendent depuis les autres barres conductrices (70B, 70C) situées à proximité de la barre conductrice longue (70A).
