A power storage device includes a plurality of power storage elements () lined up along a predetermined arrangement direction; a dividing member () that is made of insulating material and arranged between two adjacent power storage elements; a pair of end plates () that sandwich the plurality of power storage elements, and apply restraining force thereto, in the arrangement direction; and a metal connecting member () that extends in the arrangement direction and is fixed to the pair of end plates. The dividing member includes a retaining portion () that is positioned between the power storage elements and the connecting member, and that retains the connecting member.

Power storage device

An electricity storage device includes: a plurality of cells that are aligned in a predetermined direction; a pair of end plates that sandwich the plurality of cells in the predetermined direction; and a restraining member that extends in the predetermined direction, is fixed to the pair of end plates, and exerts a restraining force on the plurality of cells in the predetermined direction via the end plates. Each of the end plates includes a first plate and a second plate. The first plate has a plurality of ribs on a surface that faces the adjacent cell and is formed of insulating material. The second plate is fixed to the first plate on a side opposite to the surface that faces the adjacent cell and is formed of material stronger than the insulating material for the first plate.

Electricity storage device

A power supply apparatus that can achieve preferable holding and fixing of components constituting the power supply apparatus and can preferably prevent a liquid short-circuit and a leakage of current due to condensed water. The power supply apparatus includes a power supply unit having a plurality of power supply elements stacked with each other, an upper case and a lower case which house the power supply unit. The power supply further includes an auxiliary fastening portion which is fixed to the lower case and provides a space S between a lower surface of the power supply unit and the lower case, and fastening portions that are placed on the left and right of the power supply unit when viewed in a direction in which the power supply elements are stacked. The fastening portions fastening the power supply unit to the upper case.
