The guide portion 152 has a length in the longitudinal direction smaller than the length of the pressing portion 151, and is formed in a step shape continuously to a partial region of the pressing portion 151.

  In other words, the harness pressing member 150 is a member including a narrow portion having only the pressing portion 151 and a wide portion having a guide portion 152 formed in a step shape that is continuous with the pressing portion 151. be able to. The harness pressing member 150 is formed by molding, for example.

  As illustrated in FIG. 14, the boundary portion between the pressing portion 151 and the guide portion 152 communicates over the entire longitudinal direction of the guide portion 152. An opening 151 a is formed on the front surface of the pressing portion 151. A side wall 152 a is provided in the guide portion 152 that faces the opening portion 151 a of the pressing portion 151. Openings 152b and 152c are formed at both ends of the guide portion 152 in the longitudinal direction.

The harness pressing member 150 includes four locking pieces 153a 1 to 153a 4 and two positioning portions 156. The positioning portion 156 and the locking pieces 153a 1 to 153a 4 are formed integrally with the pressing portion 151 and the guide portion 152 by molding. The positioning portions 156 are provided at both ends in the longitudinal direction of the pressing portion 151, and have a tapered portion 156a at the tip portion. The tapered portion 156a is inserted into an opening (not shown) provided in the bracket 140 to position the bracket 140. The opening of the bracket 140 is formed to have a diameter slightly larger than the tapered portion 156a. When the tapered portion is inserted into the opening of the bracket 140, the positioning portion 156 is aligned with the center of the opening by the surrounding inclined portion.

Each of the locking pieces 153a 1 to 153a 4 has a hook 154 for engagement. Each of the locking pieces 153a 1 and 153a 2 is formed at both ends in the longitudinal direction of the pressing portion 151, and the locking piece 153a 3 is formed at the approximate center of the side wall 152a of the guide portion 152 in the longitudinal direction. 4 is provided in the vicinity of the center in the longitudinal direction of the opening 151 a of the pressing portion 151.

Each of the hooks 154 of the locking pieces 153a 1 to 153a 3 is inserted into an opening (not shown) formed in the bracket 140 by elastically deforming the locking pieces 153a 1 to 153a 4 and penetrates the opening. The hook 154 is locked to the peripheral edge of the opening by the spring back. Further, the hook 154 of the locking piece 153a 4 is inserted into the side edge of the bracket 140 by elastically deforming the locking piece 153a 4, and the hook 154 is moved to the side edge by the spring back at a position passing through the side edge. (See FIG. 7). Thereby, the harness pressing member 150 is attached to the bracket 140.

The locking piece 153a 4 provided near the center in the longitudinal direction of the opening 151a of the pressing portion 151 divides the opening 151a into two openings 151a 1 and 151a 2 in the longitudinal direction. It also has the function of increasing strength.
As described above, the harness pressing member 150 includes the pressing portion 151 having a low height and a long full width, and the pressing portion 152 having a high height and a short full width. A pair of openings 151 a 1 and 151 a 2 are provided on the front surface of the pressing portion 151. While pressing portion 152 on the pressing part 151 opening 151a 2 are provided are provided continuously, there is no pressing portion 152 at the rear of the pressing portion 151 of the aperture 151a 1 is provided. In other words, in a portion overhanging from the pressing portion 152 of the pressing portion 151, the inside of it is not spread internal space of the pressing portion 152 in the deeper openings 151a 1, deeper in the holding portion 152 of the opening 151a 2 Space expands. The walls 152a are provided on the opposite surface of the opening 151a 2.

The opening 151a 1 of the pressing portion 151, the harness assembly 810A is inserted, the opening 151a 2 of the pressing portion 151, the harness assembly 810B, 811A is inserted.
The harness assembly 810 </ b> A passes through the opening 151 a 1 of the pressing portion 151 of the harness pressing member 150 and is drawn to the back surface side of the pressing portion 151. Thereby, as described above, in the harness assembly 810A, the portion that penetrates the pressing portion 151 is pressed by the pressing portion 151 of the harness pressing member 150, and the upward lifting is suppressed.

Harness assembly 810B, 811A is inserted through the opening 151a 2 of the pressing portion 151 of the harness pressing member 150, in contact with a position before the side walls 152a of the guide portion 152, is bent to the storage module 100C side. After being bent, the harness assemblies 810 </ b> B and 811 </ b> A are guided along the inner surface of the side wall 152 a of the guide portion 152 and pulled out of the harness pressing member 150 from the opening 152 b of the guide portion 152. Thereby, as described above, the harness assemblies 810B and 811A are pressed by the pressing portion 151 of the harness pressing member 150 at the portion inserted into the pressing portion 151, and the upward lifting is suppressed. Since the height of the guide portion 152 is higher than the height of the holding portion 151, the harness assemblies 810 </ b> B and 811 </ b> A are held by the guide portion 152 in a state of floating upward in the guide portion 152.

  As described above, the portions of the harness assemblies 810A, 810B, 811A that are pressed against the pressing portion 151 of the harness pressing member 150 are set to be lower than the connector 301 of the cell control unit 300A.

  When water droplets generated by condensation in the housing 101 of the power storage device 1 adhere to the harness assemblies 810A, 810B, 811A, the water droplets flow along the surfaces of the harness assemblies 810A, 810B, 811A and flow from the higher to the lower side. . For this reason, if the connector 301 is disposed at a position lower than the harness assemblies 810A, 810B, 811A, the terminals of the connector 301 are corroded by water droplets. On the other hand, in the said embodiment, the part pressed by the holding | suppressing part 151 of the harness pressing member 150 in the harness assemblies 810A, 810B, 811A is held at a position below the connector 301. For this reason, water droplets do not flow into the connector 301. Thereby, corrosion of the connector 301 can be prevented.

  A portion of the harness assembly 810A extending from the harness pressing member 150 to the outside extends along the side surface of the power storage module 100C, is bent at one end side of the power storage module 100C, and is held by the harness guide 181. Guided. 6, connectors 852a to 852d attached to the other end of each wire harness 821 of harness assembly 810A are connected to connectors 861a to 861d of corresponding power storage modules 100A to 100C, respectively. The

In the harness assembly 810B, a portion extending to the outside from the harness pressing member 150 is bent toward the other end side of the power storage module 100C in front of the power storage module 100C, and extends along the side surface of the power storage module 100C. . Each wire harness 822 of harness assembly 810B is held and guided by harness guide 182 in the vicinity of the other end of power storage module 100C. 6, connectors 853a to 853d attached to the other end of each wire harness 822 of harness assembly 810B are connected to connectors 862a to 862d of corresponding power storage modules 100A and 100B, respectively. The
The wire harnesses 821 and 822 have the function of the connection line 810 illustrated in FIG.

In the harness assembly 811A, a portion extending from the harness pressing member 150 to the outside is bent toward one end side of the power storage module 100C before the power storage module 100C, and extends along the side surface of the power storage module 100C. The harness assembly 811A is bent toward the power storage module 100C in the vicinity of one end of the power storage module 100C. Then, as illustrated in FIG. 6, the connector 854 of each wire harness 823 of the harness assembly 811A is connected to the connector 863 of the power storage module 100C.
The wire harness 823 has the function of the connection line 811 illustrated in FIG.

  In the housing 101 of the power storage device 1, condensation is more likely to occur in the storage chamber 131D for storing the cell control unit than in the storage chamber 131D for storing the cell control unit. The reason is that the storage chambers 131 </ b> A to 131 </ b> C for storing the power storage modules are heated by heat generated from the power storage modules 100 </ b> A to 100 </ b> C. On the other hand, in the storage chamber 131D for storing the cell control unit, electronic components having the same amount of heat generation as the power storage modules 100A to 100C are not stored. It is cooled by. By being cooled by the external temperature, the inside of the storage chamber 131D for storing the cell control unit is likely to condense.

  Since there is almost no possibility of dew condensation in the storage chambers 131A to 131C for storing the power storage modules in the housing 101 of the power storage device 1, some of the wire harnesses 821, 822 and 823 are connected to the connectors 861a to 861d and 862a to 862a. It is not necessary to press down to a position lower than 862d and 863. However, the wire harnesses 821, 822, and 823 may be provided with portions that are lower than the connectors 861a to 861d, 862a to 862d, and 863.

[Mounting method of wire harness]
Next, a method for attaching the wire harnesses 821, 822, and 823 will be described.
The wire harness 821 is bundled in advance as a harness assembly 810A, the wire harness 822 as a harness assembly 810B, and the wire harness 823 as a harness assembly 811A.
The bracket 140 is fixed together with the cell control units 300A and 300B to the lower housing 101a by fastening with a fastening member.

When the connectors 851a to 851c are integrally formed as the connector 851 and the connectors 301a to 301c are integrally formed as the connector 301, it is only necessary to connect the connector 851 and the connector 301, thereby improving workability.

  The harness assemblies 810A, 810B, 811A are arranged in the storage chamber 131D for storing the cell control unit as shown in FIG. That is, the harness assembly 810A extends substantially linearly. The harness assemblies 810B and 811A extend linearly and bend toward the power storage module 100C side before the side wall 152a of the harness pressing member 150.

By covering the harness holding member 150 from above the harness aggregates 810A, 810B, 811A and inserting the positioning portion 156 of the harness holding member 150 into the opening (not shown) of the bracket 140, the harness holding member 150 with respect to the bracket 140 is inserted. Is positioned.
In this state, the harness assembly 810A is inserted into the opening 151a 1 of the pressing portion 151. The harness assemblies 810 </ b > B and 811 </ b > A are inserted into the opening portion 151 a 2 of the pressing portion 151, and a portion adjacent to the opening portion 151 a 2 is disposed below the guide portion 152.
By pressing the harness pressing member 150 downward, the hooks 154 of the locking pieces 153a 1 to 153a 4 of the harness pressing member 150 are formed on the opening (not shown) or side edge of the bracket 140, respectively. In this way, a part of the harness assemblies 810A, 810B, 811A is pressed by the pressing portion 151 of the harness pressing member 150 and held at a position lower than the connectors 301a to 301c of the cell control device 300. Is done.

Thereafter, the harness assembly 810A is bent at one end side of the power storage module 100C, held by the harness guide 181, and the connectors 852a to 852d attached to the other ends of the wire harnesses 821 are respectively connected to the corresponding power storage modules. It connects to connectors 861a to 861d of 100A to 100C. Further, the harness assembly 810B is bent toward the other end side of the power storage module 100C before the power storage module 100C, and each wire harness 822 of the harness assembly 810B is connected to the harness guide near the other end of the power storage module 100C. Hold by 182. Then, connectors 853a to 853d attached to the other end of each wire harness 822 of harness assembly 810B are connected to connectors 862a to 862d of corresponding power storage modules 100A and 100B, respectively. Further, the harness assembly 811A is bent toward the one end side of the power storage module 100C before the power storage module 100C, and is bent toward the power storage module 100C side in the vicinity of one end portion of the power storage module 100C. Then, the connector 854 of each wire harness 823 of the harness assembly 811A is connected to the connector 863 of the power storage module 100C.
In this manner, as illustrated in FIG. 6, the cell control device 300 and the power storage modules 100 </ b> A to 100 </ b> C are connected by the wire harnesses 821 to 823.
