<p>The present invention reliably and stably affixes a pair of end plates at a set position and in a compressed state by means of a binding bar. In this battery system, the pair of end plates (3) are disposed at both ends of a battery stack (2) resulting from stacking a plurality of rectangular batteries (1), and both ends of the binding bar (4) are joined to the corners of the pair of end plates (3). The binding bar (4) results from joining a horizontal section (4X) and a vertical section (4Y) to result in a cross-sectional shape that is an L-shape, and end surface plates (4T) are joined to the ends thereof. In the battery system, the horizontal section (4X) and vertical section (4Y) of the binding bar (4) are positioned at the outer peripheral surface of the end plates (3), the end surface plates (4T) press the outer surfaces of the end plates (3), the battery stack (2) is compressed in the direction of stacking by the pair of end plates (3), and a separation gap (17) at which the binding bar (4) and the end plates (3) are in a non-contacting state is provided between the inner corner (4S) of the horizontal section (4X), vertical section (4Y), and end surface plates (4T) of the binding bar (4) and the outer corner (3S) of the end plates (3).</p> |
