Embodiment Construction

[0045] Below, based on Figure 1 to Figure 11 , the embodiment of the present invention will be described.

[0046] Such as figure 1 and figure 2As shown, the power storage module M used as a power source of an electric vehicle or a hybrid vehicle includes a predetermined number (12 in the embodiment) of power storage cells 11 . . . stacked along the stacking direction. Each power storage cell 11 is formed in a rectangular parallelepiped shape, and includes a pair of main faces 11a, 11a facing each other, a pair of side faces 11b, 11b orthogonal to the main faces 11a, 11a and facing each other, and a pair of main faces 11a, 11a. The top surface 11c and the bottom surface 11d which are orthogonal to the side surfaces 11b, 11b and face each other, and positive and negative electrodes 11e, 11e are provided on the top surface 11c.

[0047] It should be noted that in this specification, the direction perpendicular to the stacking direction and connecting the top surface 11c and...

Abstract

The present invention provides an electrical storage device and a vehicle-mounted structure of the electrical storage device, capable of preventing incorrect assembly of an electrical storage module bus bar that connects electrical storage module terminals of a plurality of electrical storage modules. The power storage device (P) is configured by arranging at least first to third power storage modules (M) each composed of a plurality of power storage cells (11) in parallel, and connecting them to each other by power storage module bus bars (33A, 33B). The power storage module terminals (31A, 31B) of adjacent power storage modules (M) are electrically connected to each other. The power storage module bus bars (33A, 33B) include a long power storage module bus bar (33B) provided at one end side of the power storage module (M), and a short power storage module bus bar (33B) provided at the other end side of the power storage module (M). 33A), the long power storage module busbar (33B) is longer than the short power storage module busbar (33A), so even if you take the wrong long power storage module busbar (33B) and the short power storage module busbar (33A) to assemble, you cannot Assembling is performed, so misassembly can be prevented before it happens.

Description

technical field [0001] The present invention relates to an electric storage device and a vehicle-mounted structure of the electric storage device for mounting the electric storage device on a vehicle, wherein the electric storage device is configured by combining at least first to third storage cells each composed of a plurality of electric storage cells. The electric modules are arranged in parallel, and the electric storage module terminals of the electric storage modules adjacent to each other are electrically connected to each other by the electric storage module bus bars. Background technique [0002] The following Patent Document 1 has known a structure in which an electric storage module is formed by integrally fastening a member having a pair of end plates superimposed on the outer sides of a plurality of stacked electric storage cells by means of a stacking element, and the The lower ends of the pair of reinforcement members whose outer sides in the stacking directi...
