Abstract: A method for manufacturing a bipolar power storage device includes a first depressurizing process in which an internal space is depressurized to a first pressure through an attachment, a first liquid injecting process in which a predetermined amount of electrolyte solution is injected into the internal space from a holding member through an liquid injection port by increasing the pressure in the holding member, a second depressurizing process in which a part of the electrolyte solution flows back from the internal space to the holding member by depressurizing the internal space to a second pressure, and a second liquid injecting process in which the electrolyte solution is injected into the internal space by increasing the pressure in the holding member. The second depressurizing process includes an initial depressurizing process in which the internal space is depressurized at a depressurizing speed lower than a depressurizing speed in the first depressurizing process.

Abstract: An apparatus for manufacturing a stator includes a placement table, a supporting member and a resistance heating device. The placement table is configured to have a stator core, which has coil segments and insulators inserted in slots thereof, placed thereon. The stator core is formed of steel sheets that are laminated in an axial direction of the stator core. The coil segments together form a stator coil. The insulators are formed of a material that is foamable upon being heated. The supporting member is configured to support, in the axial direction of the stator core, distal end portions of teeth of the stator core so as to prevent gaps from being formed between the steel sheets forming the stator core. The resistance heating device is configured to heat, through energization of the stator coil, the insulators along with the stator coil and thereby cause the insulators to foam.

Abstract: An apparatus for manufacturing a stator includes a supporting member configured to support a stator core, at least one processing jig having a cylindrical part and a plurality of protruding parts, and an operating unit. The operating unit is configured to perform, in a state where each of coil protruding parts is inserted between one circumferentially-adjacent pair of the protruding parts of the processing jig and an axial end face of the stator core is located close to the protruding parts of the processing jig, a first operation and a second operation either simultaneously or alternately. The first operation is an operation of relatively rotating the stator core and the processing jig in a circumferential direction of the stator core. The second operation is an operation of relatively moving the stator core and the processing jig away from each other in an axial direction of the stator core.
