BATTERY MODULE FOR VEHICLE

摘要

An object of exemplary embodiments is to prevent increasing the height of a battery module housing a battery pack and a junction box. In the junction box, resin cases of a high-profile relay and an electric component are fixed to the shielding case wall. A low-voltage electric wire or a high-voltage electric wire is laid out on the metal plate. A resin case cover is put on when the relay and electric component is fixed to the bottom wall or the metal plate. The low-voltage electric wire or the high-voltage electric wire is covered with the case cover, predetermined contact portions of the relay and the electric component are exposed, the low-voltage electric wire or the high-voltage electric wire and a bus bar are disposed on the case cover, and the bus bar, the low-voltage electric wire or the high-voltage electric wire are connected to the exposed contact portions.

主权项

1. A battery module for a vehicle comprising:
a metal shielding case for housing a battery pack; and a junction box being housed inside the metal shielding case, the junction box having resin cases of a high profile relay, an electric component, and a resin case cover, wherein: the resin cases of the high-profile relay and the electric component are fixed to a bottom wall of the shielding case or to a surface of a metal plate fixed to the bottom wall, and a low-voltage electric wire is laid out on the metal plate, the resin case cover of the junction box is put on in a state where the relay and the electric component fixed to the bottom wall or the metal plate as well as the low-voltage electric wire are covered with the case cover, upper surfaces of the relay and the electric component are exposed through openings provided in the case cover, the case cover is fixed to the shielding case by fastening and electrically connecting contact portions provided on the upper surfaces of a high-voltage electric wire and a bus bar disposed on the case cover, and the contact portions of the relay and the electric component, which are connected to the low-voltage electric wire, are provided on side surfaces of the relay and electric component and are connected to the low-voltage electric wire, which passes through a through hole provided on a side wall of the case cover.
