A battery device is provided with: an exterior body having two outer side walls; a plurality of battery cell groups that are arranged in parallel between the two outer side walls and that are each composed of a plurality of laminated battery cells; and holding mechanisms that are arranged between the plurality of battery cell groups and that hold the plurality of respective battery cell groups in the exterior body by applying, to the plurality of battery cell groups, a pressing force in a direction in which the battery cell groups are separated from each other and are pressed towards the two opposite outer side walls.

Battery device and method for manufacturing battery device

A battery device is provided with: an exterior body having two outer side walls; at least one battery cell group that is arranged between the two outer side walls of the exterior body and that is composed of a plurality of laminated battery cells; a first temperature-adjusting medium flow path that is provided in at least one of the two outer side walls of the exterior body and in which a temperature-adjusting medium capable of exchanging heat with the battery cells via the outer side wall flows; and a holding mechanism that brings the battery cell group into contact with the outer side wall so that heat can be exchanged and that holds the battery cell group in the exterior body by applying, to the battery cell group in the exterior body, a pressing force in a direction towards the outer side wall having the first temperature-adjusting medium flow path.

Battery device including battery cell group configured by a plurality of laminated battery cells in outer packaging and method for manufacturing the battery device

A battery device includes: an exterior body having two outer side walls; a battery cell group configured by stacking battery cells each having an electrode terminal; temperature control medium flow paths provided inside the outer side walls; and a holding mechanism applying a pressure on the battery cell group in a direction of pressing the battery cell group toward the outer side wall, and holding the battery cell group. The battery cell has the electrode terminal on the upper portion. The battery cell group has a convex part protruding toward the outer side wall on a lower portion. An inner surface of the outer side wall has a concave part along the length direction of the exterior body at a lower position than the temperature control medium flow path. The battery cell group is held by the holding mechanism through engagement of the convex part and the concave part.

A hydraulic accumulator includes a limiting portion that is fitted into a ring end gap of a snap ring to limit a decrease in a diameter of the snap ring. The snap ring is stamped from a metal sheet by a press machine. Therefore, one of two opposed surfaces of a portion of the snap ring, which is fitted into a groove, forms a sloped surface as a result of shear droop. The limiting portion is fitted into the ring end gap of the snap ring to limit the decrease in the diameter of the snap ring. Thus, it is possible to limit riding of the sloped surface of the snap ring on a corner of the groove, and thereby it is possible to limit removal of the snap ring from the groove.
