Abstract: A power storage device includes: a first power storage module; a second power storage module; a case; a first attachment member that serves to couple one end portion of the first power storage module and one end portion of the second power storage module to each other, and to attach the one end portions to the case; and a second attachment member that serves to couple the other end portion of the first power storage module and the other end portion of the second power storage module to each other, and to attach the other end portions to the case. The second attachment member is lower in flexural rigidity than the first attachment member.

Abstract: A power storage device includes a plurality of power storage modules, a case, a monitoring unit, and an attachment bracket. Each of the power storage modules includes a plurality of power storage cells. The power storage modules are arranged side by side in an orthogonal direction. The monitoring unit is disposed between the case and the power storage modules. The monitoring unit includes a housing made of resin. The case includes a partition wall made of metal and an outer-side covering portion made of metal. The partition wall includes a lateral-side covering portion. The attachment bracket includes an upper-side covering portion that covers an upper side of the monitoring unit.

Abstract: A power storage device includes a plurality of power storage modules, a case, a cooler provided below the case, and a thermally conductive material. The cooler includes a cooling flow path. The power storage module includes an upstream-side stack, a downstream-side stack, and an intermediate plate. The case has a bottom wall having a protrusion protruding toward the intermediate plate. The thermally conductive material includes: an upstream-side thermally conductive portion disposed upstream of the protrusion; and a downstream-side thermally conductive portion disposed downstream of the protrusion. The downstream-side thermally conductive portion is smaller in thickness than the upstream-side thermally conductive portion.

Abstract: A vehicle includes a vehicle body, a power storage device, and a joining unit. The power storage device includes a power storage module and a power storage case. The power storage case includes a case body and a plurality of bottom surface reinforcing members. The joining unit includes a first bracket joined to a first end of a first bottom surface reinforcing member, a second bracket joined to a second end of a second bottom surface reinforcing member, and a third bracket joined to a second end of a third bottom surface reinforcing member. No joining unit is provided at a second end of the first bottom surface reinforcing member.
