DETAILED DESCRIPTION OF THE INVENTION

[0008] An embodiment of an electric vehicle will be described below with reference to FIGS. 1 to 3, directions are indicated by arrows. In FIGS. 1 and 2, Fr indicates the forward direction of the electric vehicle 100. In FIGS. 1 and 2, Rr indicates the rearward direction of the electric vehicle 100. In FIGS. 1 and 3, Rh indicates the right side as seen by a passenger facing forward of the electric vehicle 100. In FIGS. 1 and 3, Lh indicates the left side as seen by a passenger facing forward of the electric vehicle 100.

[0009] <Arrangement of the battery 14 in the electric vehicle 100> Fig. 1 shows the arrangement of the battery 14 and its peripheral components when the electric vehicle 100 is viewed from above. Fig. 2 shows the arrangement of the battery 14 and its peripheral components when the electric vehicle 100 is viewed from the direction Lh in Fig. 1. The arrangement of the components provided in the electric vehicle 100 will be described below with reference to Figs. 1 and 2.

[0010] As shown in Fig. 1, the electric vehicle 100 includes a driver's seat 12 and a passenger's seat 13. As shown in Figs. 1 and 2, the driver's seat 12 and the passenger's seat 13 include a seat surface 21, a backrest 22, and a headrest 23.

[0011] 1, the electric vehicle 100 includes a battery 14. The battery 14 contains a plurality of battery cells. The battery 14 stores electricity in the battery cells.

[0012] The battery 14 includes a middle section 15 , a front section 16 , and a rear section 17 . 1 and 2, the intermediate section 15 is disposed across the front and rear of the cabin between the driver's seat 12 and the passenger seat 13. The intermediate section 15 houses a plurality of battery cells.

[0013] 1 and 2, the front section 16 is disposed in front of the intermediate section 15. Like the intermediate section 15, the front section 16 houses a plurality of battery cells. As shown in FIG. 1, the rear section 17 is disposed behind the driver's seat 12 and the passenger seat 13. Similar to the intermediate section 15 and the front section 16, the rear section 17 houses a plurality of battery cells. As shown in FIG. 2, the upper end of the rear section 17 is located higher than the seat surface 21. In the rear section 17, a plurality of battery cells are stacked vertically upward up to a position higher than the seat surfaces 21 of the driver's seat 12 and the passenger seat 13.

[0014] In this way, the electric vehicle 100 has the batteries 14 located in front of the driver's seat 12 and passenger seat 13, between the driver's seat 12 and passenger seat 13, and behind the driver's seat 12 and passenger seat 13, rather than under the floor of the passenger compartment.

[0015] <Arrangement of the drive unit 20 and connector 19 provided in the electric vehicle 100> 1 and 2, the electric vehicle 100 includes a drive unit 20 behind the battery 14. The drive unit 20 includes a motor and a reducer.

[0016] In the drive unit 20, the motor outputs rotation using power supplied from the battery 14. In the drive unit 20, the reducer is connected to the drive shaft 24. In the drive unit 20, the reducer reduces the rotation output by the motor and transmits the reduced rotation to the drive shaft 24. In this way, in the drive unit 20, the reducer has the role of reducing the rotation of the motor and transmitting it to the drive shaft 24.

[0017] In the drive unit 20, rotation by the motor is transmitted to the drive shaft 24, causing the rear wheels 11 connected to the drive shaft 24 to rotate. That is, in the electric vehicle 100, the rear wheels 11 are drive wheels.

[0018] In this way, the electric vehicle 100 drives the drive wheels using electricity stored in the battery 14. As shown in Fig. 1, the electric vehicle 100 includes a right-side drive unit 26 and a left-side drive unit 27 as drive units 20. As shown in Fig. 1, the right-side drive unit 26 is connected to the right rear wheel of the rear wheels 11. As shown in Fig. 1, the left-side drive unit 27 is connected to the left rear wheel of the rear wheels 11.

[0019] 1 and 2, the electric vehicle 100 includes a connector 19. The connector 19 is disposed on the upper surface of the rear section 17, as shown in FIG. As shown in Figures 1 and 2, a harness 18 is connected to the connector 19 toward the rear of the electric vehicle 100. As shown in Figures 1 and 2, the harness 18 connects the connector 19 to the drive unit 20. As described above, the drive unit 20 receives power from the battery 14. The connector 19 connects the harness 18 to the battery 14. The harness 18 then supplies power from the battery 14 to the drive unit 20.

[0020] As shown in FIG. 1, the battery 14 and the connector 19 constitute a charging unit 25. <Aspects of the charging unit 25 in the electric vehicle 100> FIG. 3 shows the arrangement of the battery 14 and its surrounding components when the electric vehicle 100 is viewed from the rear.

[0021] 1 and 3, the electric vehicle 100 is provided with two connectors 19. As shown in FIGS. 1 and 3, one of the two connectors 19 is disposed behind the headrest 23 of the driver's seat 12. Also, as shown in FIGS. 1 and 3, the other connector 19 is disposed behind the headrest 23 of the passenger seat 13.

[0022] Thus, in charging unit 25, connector 19 is disposed on the upper surface of rear portion 17 at a position overlapping headrest 23 in the vehicle front-rear direction. The height of the part of the charging unit 25 located behind the headrests 23 of the driver's seat 12 and the passenger seat 13 and in the range between the headrests 23 of the driver's seat 12 and the passenger seat 13 in the vehicle width direction is adjusted to ensure rear visibility.

[0023] 3, the upper end of the rear portion 17 is located lower than the headrest 23 of the driver's seat 12 and the headrest 23 of the passenger seat 13. As described above, the connector 19 is disposed at a position overlapping the headrest 23 in the vehicle longitudinal direction. The upper end of the portion of the charging unit 25 that is located rearward of the headrest 23 of the driver's seat 12 and the headrest 23 of the passenger seat 13 and between the two headrests 23 in the vehicle width direction is located lower than the headrest 23.

[0024] <Connection of the harness 18 in the electric vehicle 100> 1 and 3, the battery 14 and the drive unit 20 are connected by a plurality of harnesses 18. Also, as shown in FIGS. 1 and 3, two connectors 19 are arranged side by side in the vehicle width direction on the upper surface of the rear portion 17.

[0025] The dashed dotted line in FIG. 3 indicates the center of the electric vehicle 100 in the vehicle width direction when the electric vehicle 100 is viewed from the rear. 3, when the electric vehicle 100 is viewed from the rear, the right-side drive unit 26 is disposed to the right of the center in the vehicle width direction of the electric vehicle 100. The left-side drive unit 27 is disposed to the left of the center in the vehicle width direction of the electric vehicle 100. As a result, the right-side drive unit 26 is disposed to the right of the left-side drive unit 27. In addition, the left-side drive unit 27 is disposed to the left of the right-side drive unit 26.

[0026] 3, the harness 18 connected to the connector 19 located to the right of the dashed dotted line is connected to a portion of the left-side drive device 27 close to the left end. In this way, the harness 18 connected to the connector 19 located to the right of the center of the electric vehicle 100 when viewed from the rear is connected to the drive device 20 to the left of the center of the electric vehicle 100 when viewed from the rear. The harness 18 connected to the connector 19 located to the right of the center of the electric vehicle 100 when viewed from the rear is connected to the left-side drive device 27.

[0027] 3, the harness 18 connected to the connector 19 located to the left of the dashed dotted line is connected to a portion of the right-side drive device 26 close to the right end. In this way, the harness 18 connected to the connector 19 located to the left of the center of the electric vehicle 100 when viewed from the rear is connected to the drive device 20 to the right of the center of the electric vehicle 100 when viewed from the rear. The harness 18 connected to the connector 19 located to the left of the center of the electric vehicle 100 when viewed from the rear is connected to the right-side drive device 26.

[0028] 3, the connector 19 located to the right of the center of the electric vehicle 100 is connected to the left-side drive unit 27, not the right-side drive unit 26. And the connector 19 located to the left of the center of the electric vehicle 100 is connected to the right-side drive unit 26, not the left-side drive unit 27.

[0029] In this way, in the electric vehicle 100, each harness 18 is connected to one of the multiple connectors 19 that is not the connector 19 closest to the location where the harness 18 is connected to the drive unit 20. When the electric vehicle 100 is viewed from the rear, each harness 18 crosses over the harnesses 18 connected to other connectors 19.

[0030] <Operation of this embodiment> Behind the driver's seat 12 and passenger seat 13, there is space that reaches at least up to the height of the backrests 22 of the driver's seat 12 and passenger seat 13. The rear section 17, which has battery cells stacked vertically above, is disposed in this space, ensuring the capacity of the battery 14. A connector 19 is disposed on the top surface of the rear section 17, and is located at a high position that is easily accessible to workers. This makes it easy for workers to attach and detach the harness 18.

[0031] <Effects of this embodiment> (1) The electric vehicle 100 described above is able to accommodate a large-capacity battery 14 while also taking into consideration the ease of attaching and detaching the harness 18.

[0032] (2) In the electric vehicle 100, the battery 14 and the drive unit 20 are connected by a plurality of harnesses 18. In the electric vehicle 100, a plurality of connectors 19 are arranged side by side in the vehicle width direction on the upper surface of the rear section 17. In the electric vehicle 100, each harness 18 is connected to one of the plurality of connectors 19 that is not the connector 19 closest to the location where the harness 18 is connected to the drive unit 20. When the electric vehicle 100 is viewed from the rear, each harness 18 intersects with harnesses 18 connected to other connectors 19.

[0033] If the harness 18 is made of a highly rigid material, and if the wiring length of the harness 18 is short, the harness 18 may not be bent sufficiently and may not be properly routed to the connector 19. In the electric vehicle 100 described above, the harness 18 is not connected to the nearest connector 19, and the wiring length of the harness 18 is made long. This allows the harness 18 to be easily connected in the electric vehicle 100, even if the harness 18 is made of a highly rigid material.

[0034] (3) When the electric vehicle 100 is viewed from the rear, the harness 18 connected to the connector 19 located to the right of the center of the electric vehicle 100 is connected to the drive unit 20 to the left of the center of the electric vehicle 100 when viewed from the rear. When the electric vehicle 100 is viewed from the rear, the harness 18 connected to the connector 19 located to the left of the center of the electric vehicle 100 is connected to the drive unit 20 to the right of the center of the electric vehicle 100 when viewed from the rear.

[0035] In the electric vehicle 100, the harness 18 connects the connector 19 and the drive unit 20 by increasing the distance from left to right or from right to left in the vehicle width direction. This allows the harness 18 to be easily connected in the electric vehicle 100 even if the harness 18 is made of a highly rigid material.

[0036] (4) The electric vehicle 100 is equipped with, as the drive units 20, a right-side drive unit 26 connected to the right rear wheel and a left-side drive unit 27 connected to the left rear wheel. When the electric vehicle 100 is viewed from the rear, the right-side drive unit 26 is disposed to the right of the left-side drive unit 27. When the electric vehicle 100 is viewed from the rear, the left-side drive unit 27 is disposed to the left of the right-side drive unit 26. When the electric vehicle 100 is viewed from the rear, the harness 18 connected to the connector 19 located to the right of the center of the electric vehicle 100 is connected to the left-side drive unit 27. When the electric vehicle 100 is viewed from the rear, the harness 18 connected to the connector 19 located to the left of the center of the electric vehicle 100 is connected to the right-side drive unit 26.

[0037] The electric vehicle 100 has drive units 20 arranged on the left and right sides in the vehicle width direction. In the electric vehicle 100, the harness 18 is routed so that the routing length of the connector 19 is long, taking into consideration the positions of the drive units 20 and the connector 19. This allows the harness 18 to be easily connected in the electric vehicle 100, even if the harness 18 is made of a highly rigid material.

[0038] (5) In the electric vehicle 100, the battery 14 and the connector 19 constitute a charging unit 25. The upper end of a portion of the charging unit 25 that is located rearward of the headrest 23 of the driver's seat 12 and the headrest 23 of the passenger seat 13 and in the range between the headrest 23 of the driver's seat 12 and the headrest 23 of the passenger seat 13 in the vehicle width direction is located lower than the headrest 23 of the driver's seat 12 and the headrest 23 of the passenger seat 13.

[0039] Because the rear section 17 of the battery 14 is stacked vertically upward, the charging unit 25 may impair rearward visibility for the user. The upper end of the portion of the charging unit 25 of the electric vehicle 100 that is located between the headrests 23 of the driver's seat 12 and the passenger seat 13 in the vehicle width direction is set lower than the headrests 23. This allows the electric vehicle 100 to ensure rearward visibility for the user.

[0040] (6) In the charging unit 25 of the electric vehicle 100, the connector 19 is disposed on the upper surface of the rear portion 17 at a position overlapping with the headrest 23 in the vehicle longitudinal direction. Because the rear portion 17 of the battery 14 is stacked vertically upward, the connector 19 may impede rearward visibility. In the electric vehicle 100, the connector 19 is disposed behind the headrest 23. This allows the electric vehicle 100 to ensure rearward visibility for the user.

[0041] (7) In the electric vehicle 100, the battery 14 includes an intermediate section 15 and a front section 16. The intermediate section 15 houses a plurality of battery cells and is disposed across the front and rear of the cabin between the driver's seat 12 and the passenger seat 13. The front section 16 houses a plurality of battery cells and is disposed in front of the intermediate section 15.

[0042] In the electric vehicle 100, the battery 14 is arranged not under the floor of the vehicle compartment, but in front of the driver's seat 12 and the passenger seat 13, between the driver's seat 12 and the passenger seat 13, and behind the driver's seat 12 and the passenger seat 13. This allows the electric vehicle 100 to ensure the capacity of the battery 14 without increasing the vehicle height, compared to when the battery 14 is arranged under the floor of the vehicle compartment.

[0043] <Example of change> This embodiment can be modified as follows: This embodiment and the following modifications can be combined and implemented within the scope of technical compatibility.

[0044] As shown in Fig. 1, the electric vehicle 100 has the driver's seat 12 located on the Lh side of Fig. 1 and the passenger seat 13 located on the Rh side of Fig. 1. The positions of the driver's seat 12 and the passenger seat 13 may be reversed. In the electric vehicle 100 described above, the rear wheels 11 are drive wheels. The electric vehicle 100 may be a four-wheel drive vehicle in which the front wheels 10 are also driven in addition to the rear wheels 11.

[0045] The electric vehicle 100 described above is equipped with two connectors 19. The number of connectors 19 equipped in the electric vehicle 100 is not limited to that in the above embodiment. That is, the electric vehicle 100 may be equipped with one connector 19, or may be equipped with three or more connectors 19.

[0046] The electric vehicle 100 has two seats: a driver's seat 12 and a passenger seat 13. The electric vehicle 100 may have three or more seats. In the above embodiment, the battery 14 includes the middle section 15, the front section 16, and the rear section 17. The battery 14 may not include either or both of the middle section 15 and the front section 16 as long as it includes the rear section 17.

[0047] The manner in which the harnesses 18 are connected in the electric vehicle 100 is not limited to the above embodiment. For example, each harness 18 may be connected to a connector 19 in a manner that does not intersect with harnesses 18 connected to other connectors 19 when the electric vehicle 100 is viewed from the rear.

[0048] In this case, when the electric vehicle 100 is viewed from the rear, the position where the harness 18 connected to the connector 19 located to the right of the center of the electric vehicle 100 is connected to the drive unit 20 does not have to be to the left of the center of the electric vehicle 100. Furthermore, when the electric vehicle 100 is viewed from the rear, the position where the harness 18 connected to the connector 19 located to the left of the center of the electric vehicle 100 is connected to the drive unit 20 does not have to be to the right of the center of the electric vehicle 100.

[0049] In this case, when the electric vehicle 100 is viewed from the rear, the harness 18 connected to the connector 19 located to the right of the center of the electric vehicle 100 may be connected to the right-side drive device 26. And when the electric vehicle 100 is viewed from the rear, the harness 18 connected to the connector 19 located to the left of the center of the electric vehicle 100 may be connected to the left-side drive device 27.

[0050] The position of the connector 19 in the electric vehicle 100 is not limited to that in the above embodiment. For example, the connector 19 of the electric vehicle 100 may be disposed in a position other than the position overlapping with the headrest 23 in the vehicle longitudinal direction.

[0051] The electric vehicle 100 described above includes a right-side drive unit 26 connected to the right rear wheel and a left-side drive unit 27 connected to the left rear wheel as the drive units 20. However, instead of including the right-side drive unit 26 and the left-side drive unit 27, the electric vehicle 100 may include drive units 20 connected to both the right rear wheel and the left rear wheel.

[0052] The charging unit 25 provided in the electric vehicle 100 is not limited to the above embodiment. FIG. 4 shows the arrangement of the battery 14 and its peripheral components when the electric vehicle 100 of the first modified example is viewed from the rear.

[0053] In Fig. 4, directions are indicated by arrows, as in Fig. 3. In Fig. 4, Rh indicates the right side as seen by a passenger facing forward of the electric vehicle 100. In Fig. 4, Lh indicates the left side as seen by a passenger facing forward of the electric vehicle 100.

[0054] The two-dot chain lines in FIG. 4 indicate the height of the lower ends of the headrests 23 of the driver's seat 12 and the passenger's seat 13. In the electric vehicle 100 of the first modified example, the lower end of the portion of the charging unit 25 that is located rearward of the headrests 23 of the driver's seat 12 and the passenger seat 13 and in the range between the headrests 23 of the driver's seat 12 and the passenger seat 13 in the vehicle width direction is located higher than in Fig. 3. Specifically, as shown in Fig. 4, in the electric vehicle 100 of the first modified example, the upper end of the rear section 17 is located higher than the lower ends of the headrests 23 of the driver's seat 12 and the passenger seat 13. Therefore, as shown in Fig. 4, the upper end of this portion is located higher than the lower ends of the headrests 23 of the driver's seat 12 and the passenger seat 13.

[0055] As shown in Fig. 4, in the electric vehicle 100 of the first modified example, the upper end of the portion in question is located higher than the lower ends of the headrests 23 of the driver's seat 12 and passenger seat 13, but the height of the upper end is kept low enough to ensure rearward visibility. Therefore, the electric vehicle 100 of the first modified example ensures rearward visibility for the user. The electric vehicle 100 may employ a configuration similar to that of the first modified example.
