Abstract: A power storage device includes a power storage module, a current collector plate, an insulating plate, and a restraint plate. The insulating plate and the restraint plate have different coefficients of thermal expansion. The insulating plate has a facing surface facing the restraint plate, and a first protruding portion provided on the facing surface in a position spaced from a center of the facing surface. The restraint plate is provided with a first hole portion into which the first protruding portion is inserted. The first protruding portion is divided into a first protrusion and a second protrusion in a second direction. The first protrusion is disposed closer to the center of the facing surface in the second direction. The second protrusion is disposed closer to an outer edge of the facing surface in the second direction.

Abstract: A voltage detection unit includes a voltage detection terminal, a housing having an accommodating concave portion to accommodate the voltage detection terminal and a cover to be attached to the housing while covering the accommodating concave portion. The cover is locked to the housing at a temporary locking position at which the cover covers a part of the accommodating concave portion and at a final locking position at which the cover covers an entirety of the accommodating concave portion. The cover includes a main body portion including a locking portion, and a locking piece. The housing includes a locked portion to be locked to the locking portion, a locking hole to accommodate the locking piece and an extending portion formed by a part of an edge of the locking hole. The locking piece is accommodated in the locking hole when the cover is at the temporary locking position.

Abstract: The power storage device includes power storage units arranged with a conductive plate interposed therebetween in the vertical direction, each of the power storage units includes an electrode stack including bipolar electrodes stacked with a separator interposed therebetween, and a sealing member provided around the electrode stack so as to seal a housing space formed between adjacent electrodes of the electrode stack. At least one of the power storage units is provided with an overhang member on an outer peripheral surface of the sealing member. The overhang member includes an inclined portion that extends from the outer peripheral surface of the sealing member toward the outside of the power storage unit and inclines downward as it leaves away from the outer peripheral surface of the sealing member, and a top portion formed at a lower end of the inclined portion.
