Abstract
(EN) A battery wiring module 10 is attached to a plurality of battery cells 20L longer in a front-rear direction and having electrode leads 21 at the front end and rear end thereof, and electrically connects the plurality of battery cells 20L. The battery wiring module 10 comprises a first busbar module 10A attached to the front side of the plurality of battery cells 20L, and a second busbar module 10B provided separately from the first busbar module 10A and attached to the rear side of the plurality of battery cells 20L. The first busbar module 10A includes a first busbar 30A connected to the electrode leads 21 protruding forwardly of the plurality of battery cells 20L, a first FPC 40 connected to the first busbar 30A, and a first protector 70A holding the first busbar 30A and the first FPC 40. The second busbar module 10B includes a second busbar 30B connected to the electrode leads 21 protruding rearwardly of the plurality of battery cells 20L, a second FPC 50 connected to the second busbar 30B, and a second protector 70B holding the second busbar 30B and the second FPC 50. In a state in which the first busbar module 10A and the second busbar module 10B are attached to the plurality of battery cells 20L, the first FPC 40 and the second FPC 50 are electrically connectable to each other.
(FR) L'invention concerne un module de câblage de batterie 10 fixé à une pluralité de cellules de batterie 20L plus longues dans une direction avant-arrière et ayant des tiges d'électrode 21 au niveau de l'extrémité avant et de l'extrémité arrière de celles-ci, et réalise la connection électrique de la pluralité de cellules de batterie 20L. Le module de câblage de batterie 10 comprend un premier module de barre omnibus 10A fixé au côté avant de la pluralité de cellules de batterie 20L, et un second module de barre omnibus 10B disposé séparément du premier module de barre omnibus 10A et fixé au côté arrière de la pluralité de cellules de batterie 20L. Le premier module de barre omnibus 10A comprend une première barre omnibus 30A connectée aux tiges d'électrode 21 faisant saillie vers l'avant de la pluralité de cellules de batterie 20L, un premier connecteur de circuit imprimé souple (FPC) 40 connecté à la première barre omnibus 30A, et un premier protecteur 70A maintenant la première barre omnibus 30A et le premier connecteur FPC 40. Le second module de barre omnibus 10B comprend une seconde barre omnibus 30B connectée aux tiges d'électrode 21 faisant saillie vers l'arrière de la pluralité de cellules de batterie 20L, un second connecteur FPC 50 connecté à la seconde barre omnibus 30B, et un second protecteur 70B maintenant la seconde barre omnibus 30B et le second connecteur FPC 50. Dans un état où le premier module de barre omnibus 10A et le second module de barre omnibus 10B sont fixés à la pluralité de cellules de batterie 20L, le premier connecteur FPC 40 et le second connecteur FPC 50 peuvent être connectés électriquement l'un à l'autre.
