Document Type and Number:
WIPO Patent Application WO/2014/034107
Kind Code:
A1
Abstract:
The present invention enables assembly work to be carried out efficiently. A power source device is provided with: a battery stacked body in which multiple rectangular batteries are stacked; a pair of end plates (3) disposed on both ends of the battery stacked body; and bind bars (4) which are connected to the end plates (3) at both ends and which secure the rectangular batteries while applying pressure to the stacking direction thereof. Connection parts (4P) disposed on both ends of the bind bars (4) are connected to the corners of the end plates (3). Moreover, the connection parts (4P) of the bind bars (4) have an L-shaped cross-section obtained by connecting horizontal parts (4X) and perpendicular parts (4Y) at a right angle, and connect to side plates (4T), which cover the outside surface of the end plates (3) at the ends of the horizontal parts (4X) and the perpendicular parts (4Y). Engagement convex parts (5) are formed on the corners of the end plates (3) facing the side plates (4T). Additionally, the bind bars (4) have engagement holes (6), which engage with the engagement convex parts (5), on the side plates (4T). Furthermore, the connection parts (4P) are connected to the end plates (3) by means of the engagement structure.
