Embodiment Construction

[0019] Examples of the present invention will be described below.

[0020] A battery pack (corresponding to an electrical storage device) according to Example 1 of the present invention will be described. figure 1 It is a schematic diagram showing the internal structure of the battery pack of this embodiment, and is a diagram viewed from above. Here, the X axis, the Y axis, and the Z axis are mutually orthogonal axes, and in this embodiment, the Z axis is set to be an axis corresponding to the vertical direction. The relationship between the X axis, the Y axis, and the Z axis is also the same in other drawings.

[0021] The battery pack of this embodiment is mounted on a vehicle (not shown), and outputs energy for running the vehicle, or stores kinetic energy generated when the vehicle brakes as regenerative power. As a vehicle, for example, a hybrid car, an electric car.

[0022] The battery pack 1 has a plurality of single cells (corresponding to power storage elements) 1...

Abstract

A power storage apparatus includes a plurality of power storage elements aligned in one direction; and a pair of restraint members placed at both ends of the plurality of power storage elements in an alignment direction in which the elements are aligned, the restraint members configured to give a restraint force to the plurality of power storage elements. At least one restraint member of the pair of restraint members includes, a protruding portion protruding toward the power storage element adjacent to the restraint member, an end of the protruding portion being in contact with the adjacent power storage element to form a space between the restraint member and the adjacent power storage element; and a shield portion protruding in the alignment direction and preventing a heat exchange medium for use in temperature adjustment of the power storage element from entering into the space.

Description

technical field [0001] The present invention relates to an electrical storage device that exerts restraint force on a plurality of electrical storage elements in a structure in which the electrical storage elements are arranged side by side in one direction. Background technique [0002] In a battery pack including a plurality of cells, the cells are arranged side by side in one direction, and have a structure that exerts restraint on the cells. Specifically, a restraining force is applied to the plurality of cells by a pair of constraining members disposed at positions sandwiching the plurality of cells. The constraining force is a force that displaces two cells arranged adjacently in a direction toward each other. [0003] Among the plurality of cells, the cells located at both ends in the arrangement direction, in other words, the cells that are in contact with the constraining member tend to have higher heat dissipation properties than the other cells. In addition, the...
