The reinforcing section 180 is located behind the junction box 300, the electronic equipment 400, the second electronic equipment 500, and the base 600. The reinforcing section 180 is located behind the battery module 200. The reinforcing section 180 is joined to the bottom surface 170 by welding or the like.

[0040] The battery module 200 includes multiple battery stacks. Each battery stack consists of multiple battery cells arranged in a grid. The battery cells are rechargeable batteries such as nickel-metal hydride batteries or lithium-ion batteries. The battery cells may use a liquid electrolyte or a solid electrolyte.

[0041] The battery module 200 is housed in the battery pack 100. The battery module 200 is positioned between the first side portion 130 and the second side portion 140. The battery module 200 is not positioned between the inclined surface portion 110 and the second side portion 140. The battery module 200 is positioned behind the junction box 300, the electronic equipment 400, the second electronic equipment 500, and the base 600. The battery module 200 is electrically connected to the junction box 300.

[0042] The junction box 300 includes a first heat-generating component group 310 and a second heat-generating component group 320. When the junction box 300 is energized with the battery module 200, the first heat-generating component group 310 is configured to rise to a higher temperature than the second heat-generating component group 320. Furthermore, at least the first heat-generating component group 310 does not overlap the base 600 in the vertical direction.

[0046] The electronic equipment 400 and the second electronic equipment 500 are mounted on the base 600. Each of the electronic equipment 400 and the second electronic equipment 500 is smaller than the junction box 300 when viewed from above. The electronic equipment 400 and the second electronic equipment 500 are arranged side-by-side in the vertical direction. For example, one of the electronic equipment 400 and the second electronic equipment 500 may be an ECU and the other a Satellite Battery Monitor (SBM).

[0047] The SBM is a monitoring unit that monitors the status of the battery module 200. This status includes temperature, voltage, and / or current. The ECU may control each device so that the vehicle 1 reaches a desired state based on signals received from the SBM, information such as programs stored in memory, etc. In addition to the SBM, the ECU may be configured to receive signals from various sensors (not shown) (e.g., accelerator opening signal, vehicle speed signal, etc.).

[0048] The base 600 is located between the exhaust pipe 50 and the junction box 300 when viewed from above, and is aligned with the junction box 300 in the width direction of the vehicle 1. The base 600 is located at the rear of the vehicle on the inclined surface 110. The base 600 is aligned with the inclined surface 110 in the width direction of the vehicle 1.

[0049] The base 600 includes a plurality of support sections 610, a wall section 620, and a second wall section 630. The wall section 620 may also be referred to as the first wall section.

In this embodiment, the second support portion 612 is located below the first support portion 611. The first support portion 611 and the second support portion 612 are plate-shaped members. The first support portion 611 is fixed to the wall portion 620 and the second wall portion 630 by a plurality of fastening members F.

[0051] The wall portion 620 is located between the electronic device 400 and the battery pack 100 in the front-rear direction. More specifically, the wall portion 620 is located between the electronic device 400 and the inclined surface portion 110 in the front-rear direction.

[0052] The wall portion 620 extends from the front of the electronic device 400 to above the electronic device 400. The wall portion 620 extends from the front of the second electronic device 500 to above the second electronic device 500. The wall portion 620 extends above the battery module 200. However, the upper end portion 621 of the wall portion 620 is separated from the battery pack 100 above. The upper end portion 621 is located in front of the electronic device 400.

[0053] The lower end portion 622 of the wall portion 620 is located below the electronic equipment 400 and the second electronic equipment 500. The lower end portion 622 of the wall portion 620 is in contact with the battery pack 100 below. The lower end portion of the wall portion 620 is joined to the bottom surface portion 170 of the battery pack 100, for example, by welding.

[0054] The wall portion 620 further includes a central wall portion 623, a first rear extension portion 624, and a second rear extension portion 625. The central wall portion 623 is located in front of the second electronic device 500. The central wall portion 623 extends downward from the upper end portion 621. The first rear extension portion 624 extends rearward from the lower end of the upper end portion 621 (i.e., the upper end of the central wall portion 623). The first rear extension portion 624 is fixed to the first support portion 611 by a fastening member F. The second rear extension portion 625 extends rearward from the lower end of the central wall portion 623. The second rear extension portion 625 is fixed to both the second support portion 612 and the lower end portion 622 by a fastening member F.

[0055] The second wall portion 630 is located behind the electronic device 400 and the second electronic device 500. More specifically, the second wall portion 630 is located below the electronic device 400. The lower end portion 632 of the second wall portion 630 is fixed to the second support portion 612 and the reinforcing portion 180 of the battery pack 100 by fastening members F.

[0056] As described above, the vehicle 1 according to this embodiment includes an exhaust pipe 50, a battery pack 100, a junction box 300, electronic equipment 400, and a base 600. The exhaust pipe 50 is located outside the battery pack 100. The battery pack 100 houses the junction box 300, the electronic equipment 400, and the base 600. The electronic equipment 400 is mounted on the base 600. When viewed from above, the base 600 is located between the exhaust pipe 50 and the junction box 300, and is aligned with the junction box 300 in the width direction of the vehicle 1.

[0057] According to the above configuration, the base 600 on which the electronic equipment 400 is mounted is aligned with the junction box 300 in the width direction of the vehicle 1 when viewed from above, thereby preventing the electronic equipment 400 from being heated from below by the heat generated from the junction box 300. Furthermore, a large space for housing the battery pack 100 can be secured in front of or behind the junction box 300 and the base 600. For example, the battery pack 100 can have a large space for housing the battery module 200. Consequently, it becomes possible to increase the capacity of the battery module 200.

[0058] Therefore, with the above configuration, it is possible to increase the storage space within the battery pack 100 while suppressing the junction box 300 from overheating the electronic equipment 400.

[0059] Now, in Figures 3 and 4, the flow of heat is indicated by the symbol h. As shown in Figure 3, in this embodiment, the heat transferred to the battery pack 100 via the exhaust pipe 50 and heater insulator 60, using the exhaust gas flowing through the exhaust pipe 50 as the heat source, and the flow of heat transferred from the engine 10 to the battery pack 100 are shown. This heat reaches the front of the front portion 120 of the battery pack 100, then passes between the top portion 160 and the floor panel 21, and flows further to the rear of the battery pack 100. On the other hand, as shown in Figure 4, in this embodiment, the heat transferred to the battery pack 100 via the exhaust pipe 50 and heater insulator 60, using the exhaust gas flowing through the exhaust pipe 50 as the heat source, are shown. This heat can further be transferred to the interior of the battery pack 100 via the inclined surface portion 110.

[0060] Therefore, in this embodiment, the base 600 includes a support portion 610 and a wall portion 620. The support portion 610 supports the electronic device 400. The wall portion 620 is located between the electronic device 400 and the battery pack 100 in the longitudinal direction of the vehicle. The wall portion 620 extends from the front of the electronic device 400 to above the electronic device 400.

[0061] According to the above configuration, the wall portion 620 can suppress the transfer of heat from the exhaust pipe 50 to the battery pack 100 to the electronic equipment 400.

[0062] Furthermore, the vehicle 1 according to this embodiment further comprises a battery module 200. The battery pack 100 further houses the battery module 200. The wall portion 620 extends above the battery module 200.

[0063] According to the above configuration, the upper end portion 621 of the wall portion 620 is located at a relatively high position relative to other components housed within the battery pack 100. This further suppresses the transfer of heat from the exhaust pipe 50 to the battery pack 100 to the electronic equipment 400.

[0064] Furthermore, in this embodiment, the upper end portion 621 of the wall portion 620 is separated from the battery pack 100 above.

[0065] According to the above configuration, the wall portion 620 further suppresses the transfer of heat from the exhaust pipe 50 to the battery pack 100 to the electronic equipment 400, while also suppressing contact between the wall portion 620 and the battery pack 100 when the vehicle 1 vibrates.

[0066] Furthermore, in this embodiment, the lower end portion 622 of the wall portion 620 is in contact with the battery pack 100 at the bottom.

[0067] According to the above configuration, the wall portion 620 can further suppress the transfer of heat from the exhaust pipe 50 to the battery pack 100 to the electronic equipment 400.

[0068] Furthermore, in this embodiment, the lower end portion 622 of the wall portion 620 is joined to the battery pack 100.

[0069] According to the above configuration, the wall portion 620 further suppresses the transfer of heat from the exhaust pipe 50 to the battery pack 100 to the electronic equipment 400, while also stabilizing the base 600 on which the electronic equipment 400 is mounted.

[0070] In this embodiment, the base 600 further includes a second wall portion 630. The second wall portion 630 is located behind the electronic device 400. The lower ends 622 and 632 of the second wall portion 630 are joined to the battery pack 100. The support portion 610 is connected to both the wall portion 620 and the second wall portion 630.

[0071] According to the above configuration, the base 600 can stably support the electronic device 400. Furthermore, this embodiment further includes a second electronic device 500. The base 600 includes a plurality of support parts 610. The plurality of support parts 610 include a first support part 611 and a second support part 612. The first support part 611 supports the electronic device 400. The second support part 612 supports the second electronic device 500. The second support part 612 is located above or below the first support part 611.

[0072] According to the above configuration, even when the battery pack 100 further accommodates the second electronic device 500, ample space for housing the battery pack 100 can be secured in front of or behind the junction box 300 and the base 600.

[0073] Furthermore, the vehicle 1 according to this embodiment is further equipped with a heater insulator 60. The heater insulator 60 is located between the battery pack 100 and the exhaust pipe 50.

[0074] According to the above configuration, it is possible to suppress the transfer of heat from the exhaust pipe 50 to the battery pack 100.

[0075] In this embodiment, the battery pack 100 also includes an inclined surface portion 110. The inclined surface portion 110 is aligned with the junction box 300 in the width direction of the vehicle 1. The inclined surface portion 110 extends so as it approaches the front of the vehicle, it tilts toward the junction box 300 in the width direction of the vehicle 1. The exhaust pipe 50 extends along the inclined surface portion 110. The base 600 is located behind the inclined surface portion 110 of the vehicle.

[0076] With the above configuration, the electronic equipment 400 can be placed in the gap between the relatively large junction box 300 and the inclined surface 110. At the same time, ample space for housing the battery pack 100 can be secured in front of or behind the junction box 300 and the base 600.

[0077] Furthermore, in this embodiment, the vehicle 1 according to this embodiment further comprises a battery module 200. The battery module 200 is housed in the battery pack 100. The battery module 200 is electrically connected to a junction box 300. The junction box 300 includes a first heat-generating component group 310 and a second heat-generating component group 320. When the junction box 300 is energized to the battery module 200, the first heat-generating component group 310 is configured to rise to a higher temperature than the second heat-generating component group 320. The first heat-generating component group 310 does not overlap the base 600 in the vertical direction.

[0078] According to the above configuration, a distance can be secured between the first heat-generating component group 310, which reaches relatively high temperatures, and the base 600, thereby suppressing the transfer of heat from the first heat-generating component group 310 to the electronic device 400.

[0079] In this embodiment, the first heat-generating component group 310 includes a relay 311, a fuse 312, a register 313, a current sensor 314, or a terminal 315.

[0080] According to the above configuration, a distance can be ensured between at least one component that reaches a relatively high temperature and the base 600, thereby suppressing the transfer of heat from that component to the electronic device 400.

[0081] Furthermore, in this embodiment, the first heat-generating component group 310 includes a relay 311, a fuse 312, a register 313, a current sensor 314, and a terminal 315.

[0082] According to the above configuration, a distance can be maintained between these components, which become relatively hot, and the base 600, thereby suppressing the transfer of heat from these components to the electronic device 400.

[0083] Furthermore, in this embodiment, the junction box 300 does not overlap with the base 600 in the vertical direction.

[0084] According to the above configuration, the distance between the junction box 300 and the base 600 can be made even larger, and consequently, the transfer of heat from the junction box 300 to the electronic equipment 400 can be further suppressed.

[0085] (Embodiment 2) Next, a vehicle according to Embodiment 2 of this disclosure will be described. The vehicle according to Embodiment 2 has a different configuration of the wall portion 620 compared to vehicle 1 according to Embodiment 1. For this reason, the same configuration and effects as those of vehicle 1 according to Embodiment 1 will not be described again.

[0086] Figure 5 is a partial cross-sectional view of a vehicle according to Embodiment 2. The cross-sectional view shown in Figure 5 in Embodiment 2 corresponds to the cross-sectional view shown in Figure 4 in Embodiment 1.

[0087] As shown in Figure 5, in Embodiment 2, the base 600 further includes a cushioning member 650. The cushioning member 650 has less rigidity than the wall portion 620. The cushioning member 650 is in contact with the upper side of the wall portion 620. The battery pack 100 is in contact with the upper side of the cushioning member 650.

[0088] According to the above configuration, the wall portion 620 and the buffer member 650 further suppress the transfer of heat from the exhaust pipe 50 to the battery pack 100 to the electronic equipment 400, while also suppressing direct contact between the wall portion 620 and the battery pack 100 when the vehicle 1 vibrates.

[0089] More specifically, the cushioning member 650 is in contact with the upper side of the upper end portion 621 of the wall portion 620. The cushioning member 650 is in contact with the top surface portion 160.

[0090] In the above-described embodiment, the combinatable configurations may be combined with each other.

[0091] The embodiments disclosed herein should be considered in all respects to be illustrative and not restrictive. The scope of this disclosure is indicated by the claims rather than the foregoing description, and all modifications within the meaning and scope equivalent to the claims are intended.
