Description

Vehicle 【0001】 This application claims the priority of Japanese Patent Application No. 2024-217096 filed on December 11, 2024, and the entire content thereof is incorporated herein by reference. This disclosure relates to a vehicle. 【0002】 A vehicle including a storage case, a power storage module provided in the storage case, an electronic device provided in the storage case, an exhaust pipe disposed on the side of the storage case, and a cooling pipe for cooling the power storage module has been conventionally known (see, for example, Japanese Unexamined Patent Application Publication No. 2021-034251). In this vehicle, a part of the cooling pipe is disposed between the electronic device and the exhaust pipe to suppress heating of the electronic device. 【0003】 However, with the above configuration, since the cooling pipe itself is affected by heat from the exhaust pipe, the cooling performance for the power storage module may decrease. 【0004】 Therefore, this disclosure provides a vehicle capable of reducing the heat influence of an exhaust pipe on a cooling pipe for cooling a power storage module. 【0005】 A vehicle according to a first aspect of the present disclosure includes a power storage device having a case that houses a power storage module, an exhaust pipe disposed adjacent to the outside in the vehicle width direction of the case, a device connector provided at the front end portion of the case in the vehicle front side, a cooling pipe routed so as to be able to cool the power storage module, and an inlet portion and an outlet portion provided at the front end portion of the case in the vehicle front side in a plan view and on the opposite side of the exhaust pipe across the device connector for flowing a refrigerant to the cooling pipe. 【0006】 According to the first aspect, the power storage device has a case that houses a power storage module, and an exhaust pipe is disposed adjacent to the outside in the vehicle width direction of the case. And a device connector is provided at the front end portion of the case in the vehicle front side. Also, the cooling pipe is routed so as to be able to cool the power storage module. 【0007】Here, the inlet and outlet for supplying refrigerant to the cooling pipe are located, in a plan view, at the front end of the case on the vehicle side, and on the opposite side of the exhaust pipe from the equipment connector. Therefore, the thermal influence of the exhaust pipe on the inlet and outlet is reduced. In other words, the thermal influence of the exhaust pipe on the cooling pipe that cools the energy storage module is reduced. 【0008】 Furthermore, the vehicle of the second embodiment of the present disclosure is the vehicle of the first embodiment, wherein the inlet is located further from the exhaust pipe than the outlet. 【0009】 According to the second embodiment, the inlet is located further from the exhaust pipe than the outlet. Therefore, compared to the case where the inlet is located closer to the exhaust pipe than the outlet, the thermal influence of the exhaust pipe on the refrigerant flowing into the cooling pipe is reduced, and the reduction in cooling efficiency due to the refrigerant flowing through the cooling pipe is suppressed. 【0010】 Furthermore, the vehicle of the third embodiment of the present disclosure is the vehicle of the first or second embodiment, wherein electronic equipment is provided inside the case, which, in a plan view, overlaps with a portion of the cooling pipe. 【0011】 According to the third embodiment, the electronic equipment installed inside the case overlaps with a portion of the cooling pipe in a plan view. Therefore, the electronic equipment is cooled more efficiently than in the case where it does not overlap with the cooling pipe in a plan view. 【0012】 Furthermore, the vehicle of the fourth embodiment of the present disclosure is the vehicle of the third embodiment, wherein a junction box is provided on the vehicle-front side of the energy storage module inside the case, and when viewed from the front-rear direction of the vehicle, at least a part of the junction box is positioned between the cooling pipe and the electronic equipment. 【0013】According to the fourth embodiment, a junction box is provided on the vehicle-front side of the energy storage module inside the case, and at least a portion of the junction box is positioned between the cooling pipe and the electronic equipment when viewed from the front-rear direction of the vehicle. Therefore, the junction box is cooled more efficiently and the space efficiency inside the case is improved compared to a case where at least a portion of the junction box is not positioned between the cooling pipe and the electronic equipment when viewed from the front-rear direction of the vehicle. 【0014】 Furthermore, the fifth embodiment of the vehicle relating to this disclosure is the fourth embodiment of the vehicle, wherein a first space is provided on the upper side of the case that extends in the longitudinal direction of the vehicle, and a second space is provided on the upper side of the junction box inside the case and on the lower side of the first space when viewed from the longitudinal direction of the vehicle. 【0015】 According to the fifth embodiment, a first space is provided on the upper side of the case that extends in the longitudinal direction of the vehicle, and a second space is provided on the upper side of the junction box inside the case and on the lower side of the first space when viewed from the longitudinal direction of the vehicle. Therefore, compared to a case where the second space is not provided, for example, where electronic equipment is placed in the second space, the heat dissipation of the junction box is improved and the thermal impact on the electronic equipment can be prevented. 【0016】 Furthermore, the vehicle of the sixth embodiment of the present disclosure is the vehicle of the fourth or fifth embodiment, wherein a detector for detecting voltage abnormalities in the energy storage module is provided on the outside in the vehicle width direction of the junction box inside the case and on the vehicle front side of the energy storage module. 【0017】 According to the sixth embodiment, a detector for detecting voltage abnormalities in the energy storage module is provided inside the case on the outside in the vehicle width direction of the junction box and on the vehicle front side of the energy storage module. Therefore, in a plan view, the wiring connecting the detector and the energy storage module does not need to overlap with the junction box, and the thermal influence from the junction box on the wiring is reduced. 【0018】 Furthermore, the seventh embodiment of the vehicle relating to this disclosure is the vehicle of the sixth embodiment, wherein the detector is positioned away from the lower and upper walls of the case. 【0019】 According to the seventh embodiment, the detector is positioned away from the lower and upper walls of the case. Therefore, the thermal influence from the lower and upper walls of the case is reduced compared to when the detector is positioned close to the lower or upper wall of the case. 【0020】 Furthermore, the eighth embodiment of the vehicle relating to this disclosure is the fourth embodiment of the vehicle, wherein a detector for detecting voltage abnormalities in the energy storage module is provided on the vehicle-upper side of the junction box inside the case. 【0021】 According to the eighth aspect, a detector for detecting voltage abnormalities in the energy storage module is provided inside the case on the vehicle-upper side of the junction box. Therefore, compared to the case where the detector is provided on the outside in the vehicle-width direction of the junction box, it is possible to reduce the size of the case in the vehicle-width direction, thereby achieving miniaturization of the energy storage device. 【0022】 As described above, this disclosure makes it possible to reduce the thermal impact of the exhaust pipe on the cooling pipe that cools the energy storage module. 【0023】 This is a schematic plan view showing the layout around the energy storage device of a vehicle according to the first embodiment. This is a schematic rear view showing the layout around the energy storage device of a vehicle according to the first embodiment. This is a schematic plan view showing the busbars and wiring inside the case of the energy storage device of a vehicle according to the first embodiment. This is a schematic rear view showing the layout around the energy storage device of a vehicle according to the second embodiment. 【0024】 The embodiments relating to this disclosure will be described in detail below with reference to the drawings. For the sake of explanation, in each figure, the arrow UP will indicate the upward direction of the vehicle, the arrow FR will indicate the forward direction of the vehicle, and the arrow RH will indicate the rightward direction of the vehicle. In the following description, unless otherwise specified, the directions of up, down, front, back, and left and right will refer to the up, down, front, back, and left and right directions of the vehicle. The left and right direction is synonymous with the vehicle width direction. 【0025】<First Embodiment> First, the first embodiment will be described. As shown in Figures 1 and 2, the vehicle 10 according to the first embodiment is equipped with a power storage device 20 on the lower side of the floor 12. The power storage device 20 has a metal case 22 which is roughly rectangular in shape, and a power storage module 30 is housed inside the case 22. The case 22 is composed of a lower case 24 and an upper case 26. 【0026】 The lower case 24 has a lower wall 24D, a lower peripheral wall 24A integrally erected on the periphery of the lower wall 24D, and a lower flange portion 24B integrally projecting outward from the lower peripheral wall 24A. The upper case 26 has an upper wall 26U, an upper peripheral wall 26A integrally vertically attached on the periphery of the upper wall 26U, and an upper flange portion 26B integrally projecting outward from the upper peripheral wall 26A. 【0027】 The case 22 is formed in a roughly rectangular box shape by overlapping the upper flange portion 26B and the lower flange portion 24B vertically and joining them by welding or the like. As shown in Figure 1, in a plan view, a stepped portion 28 that is recessed toward the rear is formed at the right end (the end on the exhaust pipe 14 side, which will be described later) of the front end (front side) of the case 22. 【0028】 Adjacent to the right side of case 22 (outer side in the vehicle width direction) is an exhaust pipe 14 that carries exhaust from the engine (not shown) housed in the engine compartment. Specifically, in a plan view, this exhaust pipe 14 is positioned substantially along the lower peripheral wall 24A of case 22, including the stepped portion 28, and extends towards the rear. 【0029】 Furthermore, an insulator 16 is provided between the case 22 and the exhaust pipe 14 to reduce the thermal influence from the exhaust pipe 14 on the energy storage device 20 (indicated by arrow H1 in Figure 2). Also, as shown in Figure 2, a shear panel 18 is positioned below the case 22, covering the entire lower surface of the lower wall 24D of the case 22 with a predetermined gap in the vertical direction. 【0030】As shown in Figure 1, a plurality (for example, two) of equipment connectors 34 are arranged in a line in the vehicle width direction at approximately the center of the front end of the case 22. Each equipment connector 34 is connected to a harness 38 routed from the front side (engine compartment side). 【0031】 Each equipment connector 34 protrudes integrally from the front wall 32F of the junction box 32, which will be described later, and protrudes forward from the opening 22A formed in the front wall 22F of the case 22 (the front portion of the lower peripheral wall 24A and the upper peripheral wall 26A). In addition, each equipment connector 34 is positioned to the left of the stepped portion 28 of the case 22 (on the opposite side from the exhaust pipe 14) so ​​that each harness 38 does not come into contact with the exhaust pipe 14. 【0032】 A junction box 32 is provided inside the case 22. The junction box 32 is formed in a roughly rectangular parallelepiped shape with the vehicle width direction as its longitudinal direction, and is located on the front side of the energy storage module 30, i.e., at the front end inside the case 22. In plan view, the junction box 32 extends in the left-right direction to a position where its right end face (exhaust pipe 14 side) does not reach the stepped portion 28. 【0033】 Furthermore, as shown in Figure 2, in a rear view from the rear of the vehicle 10 (viewed from the front-to-rear direction of the vehicle 10), the junction box 32 has a stepped portion 32L on its left side (the portion to the left of the floor tunnel portion 12A, which will be described later) that is lower in height than the right side, and an electronic control unit (ECU) 40 is provided as an electronic device on the upper wall 32U of the stepped portion 32L. 【0034】As shown in Figures 1 and 2, the ECU 40 has a roughly rectangular box-shaped case 42 with the vertical direction as the thickness direction and the horizontal direction as the longitudinal direction, and is formed to be considerably smaller (especially in thickness) than the junction box 32 in a plan view. As shown in Figure 2, the upper ends of a pair of left and right legs 44 are attached to the outer side in the vehicle width direction on the lower surface of the case 42 of the ECU 40, and the lower ends of each leg 44 are attached to the upper wall 32U of the junction box 32. As a result, the ECU 40 is positioned on the upper wall 32U of the junction box 32 with a predetermined gap between them. 【0035】 Furthermore, as shown in Figures 1 and 2, a cooling pipe 36 for cooling the energy storage module 30 is provided in contact with the lower surface of the lower wall 24D of the case 22 above the share panel 18. This cooling pipe 36 is arranged to overlap the energy storage module 30 in a plan view so that it can cool the energy storage module 30 via the lower wall 24D of the case 22. 【0036】 Specifically, the energy storage module 30 has multiple battery stacks 30A arranged in the front-to-back direction, with the vehicle width direction as its longitudinal direction. Therefore, the cooling pipes 36 are positioned directly below each battery stack 30A, along the longitudinal direction of each battery stack 30A. Each battery stack 30A contains multiple battery cells (not shown) stacked in the vehicle width direction. 【0037】 Furthermore, the cooling pipe 36 has an inlet section 36A which serves as the inlet for the refrigerant flowing inside it, and an outlet section 36B which serves as the outlet for the refrigerant. That is, the refrigerant that flows in from the inlet section 36A cools the energy storage module 30 (exchanges heat with the energy storage module 30) as it flows through the cooling pipe 36, and the refrigerant that has exchanged heat with the energy storage module 30 flows out from the outlet section 36B. 【0038】Furthermore, the inlet portion 36A and the outlet portion 36B are located at the front end of the case 22 in a plan view, on the opposite side from the exhaust pipe 14, with the equipment connector 34 in between. In other words, the inlet portion 36A and the outlet portion 36B are attached to and supported on the left end side (one end in the vehicle width direction) of the front wall 22F of the case 22. 【0039】 Furthermore, the inlet section 36A is located further from the exhaust pipe 14 than the outlet section 36B. That is, the inlet section 36A is located on the left end side (one end side in the vehicle width direction) than the outlet section 36B. A refrigerant supply pipe 46, routed from the front, is connected to the inlet section 36A, and a refrigerant discharge pipe 48, routed from the front, is connected to the outlet section 36B. 【0040】 Furthermore, as shown in Figure 1, the ECU 40 is positioned so as to overlap a portion of the cooling pipe 36 in a plan view. More specifically, in a plan view, the cooling pipe 36 has a straight section 36C that extends straight from the inlet section 36A and the outlet section 36B toward the rear. The left side of the junction box 32 is positioned above the straight section 36C, and the ECU 40 is positioned above the left side of the junction box 32. 【0041】 As a result, in a plan view, the ECU 40 overlaps with the straight section 36C, which is part of the cooling pipe 36. Furthermore, as shown in Figure 2, in a rear view, the left portion, which is part of the junction box 32, is positioned between the straight section 36C of the cooling pipe 36 and the ECU 40. 【0042】 Furthermore, as shown in Figures 1 and 2, a detector 50 is provided inside the case 22 to measure the voltage of the energy storage module 30 and detect any voltage abnormalities. Specifically, this detector 50 is located on the right side (outside in the vehicle width direction) of the junction box 32 and in front of the energy storage module 30. In other words, this detector 50 is located inside the stepped portion 28 of the case 22. 【0043】Detector 50 has a substantially rectangular box-shaped case 52 with the vertical direction being the thickness direction and the horizontal direction being the longitudinal direction. The case 52 is formed to be considerably smaller (especially thinner) than the junction box 32. As shown in FIG. 2, at the lower surface of the case 52, the upper end portions of legs 54 having a substantially hat-shaped configuration in a rear view with the lower side being the open side are attached, and the lower end portions of the legs 54 are attached to the upper surface of the lower wall 24D of the case 22. 【0044】 As a result, the detector 50 is configured to be disposed on the lower wall 24D of the case 22 with a predetermined gap therebetween. Note that the detector 50 is configured to be disposed at a substantially central portion in the height direction of the case 22 by the legs 54 and also has a predetermined gap from the upper wall 26U of the case 22. That is, the detector 50 is configured to be disposed at a predetermined distance from the lower wall 24D and the upper wall 26U of the case 22, respectively. 【0045】 Also, as shown in FIG. 2, a floor tunnel portion 12A extending in the front-rear direction is formed at the center in the vehicle width direction of the floor 12. By this floor tunnel portion 12A, a first space portion S1 extending in the front-rear direction is formed above the case 22 and at the center in the vehicle width direction. 【0046】 And, in a rear view, a second space portion S2 is provided in a portion located above the junction box 32 and below the floor tunnel portion 12A (first space portion S1) inside the case 22. In other words, no other electronic devices or the like are arranged in that portion. 【0047】 Also, as shown in FIG. 3, the power storage module 30 is configured such that a plurality of battery stacks 30A are connected in series by a bus bar 31. And the bus bar 31 is connected to a connector (not shown) provided on the rear wall 32B of the junction box 32. 【0048】Further, wiring 56 for measuring the voltage of each battery stack 30A is connected to each battery stack 30A. The wiring 56 is connected to a connector (not shown) provided on the rear wall 52B of the case 52 of the detector 50. In FIG. 3, the illustration of the cooling pipe 36 is omitted in order to show the bus bar 31 and the wiring 56. 【0049】 Next, the operation of the vehicle 10 according to the first embodiment configured as described above will be described. 【0050】 As described above, the power storage device 20 has a case 22 that houses the power storage module 30, and an exhaust pipe 14 is disposed adjacent to the right side (outer side in the vehicle width direction) of the case 22. A device connector 34 is provided at the front end of the case 22. The cooling pipe 36 is provided in contact with the lower surface of the lower wall 24D of the case 22 and is routed to be able to cool the power storage module 30 (each battery stack 30A). Therefore, the power storage module 30 (each battery stack 30A) is effectively cooled by the cooling pipe 36. 【0051】 Here, an inlet portion 36A and an outlet portion 36B for flowing a refrigerant into the cooling pipe 36 are provided at the front end portion of the case 22 in a plan view, on the side opposite to the exhaust pipe 14 across the device connector 34, that is, on the left end side. Therefore, the heat influence of the exhaust pipe 14 on the inlet portion 36A and the outlet portion 36B can be reduced. That is, the heat influence of the exhaust pipe 14 on the cooling pipe 36 that cools the power storage module 30 can be reduced. 【0052】 Moreover, the inlet portion 36A is provided at a position farther from the exhaust pipe 14 than the outlet portion 36B, that is, on the left end side. Therefore, compared with the case where the inlet portion 36A is provided at a position closer to the exhaust pipe 14 than the outlet portion 36B (that is, on the right side), the heat influence of the exhaust pipe 14 on the refrigerant flowing into the cooling pipe 36 and the heat reception from the junction box 32 can be reduced, and the reduction in the cooling efficiency of the power storage module 30 by the refrigerant flowing through the cooling pipe 36 can be suppressed. 【0053】Furthermore, the ECU 40, located inside the case 22, overlaps with the straight section 36C, which is part of the cooling pipe 36, in a plan view. Therefore, the ECU 40 can be cooled more efficiently by the cooling pipe 36 compared to the case where the ECU 40 does not overlap with the cooling pipe 36 in a plan view. This configuration is particularly effective because the ECU 40 is sensitive to heat. 【0054】 Furthermore, since the ECU 40 is located to the left of the floor tunnel section 12A (away from directly below the floor tunnel section 12A), the thermal influence on the ECU 40 from inside the floor tunnel section 12A (first space section S1) (described later) can be reduced. Also, since the ECU 40 is located far from the exhaust pipe 14, the thermal influence on the ECU 40 from the exhaust pipe 14 can also be reduced. 【0055】 Furthermore, since a predetermined gap is formed between the ECU 40 and the upper wall 32U of the junction box 32 by the legs 44, the thermal influence from the junction box 32 on the ECU 40 can be reduced compared to the case where the case 42 of the ECU 40 is directly placed on the upper wall 32U of the junction box 32. 【0056】 Furthermore, within the case 22, the junction box 32 is located on the front side of the energy storage module 30, and the left portion (at least a part) of the junction box 32 is positioned between the cooling pipe 36 and the ECU 40 when viewed from the rear. Therefore, compared to a case where at least a part of the junction box 32 is not positioned between the cooling pipe 36 and the ECU 40 when viewed from the rear, the junction box 32 can be cooled more efficiently (indicated by arrow C in Figure 2), and the space efficiency within the case 22 can be improved. 【0057】Furthermore, within the case 22, the busbars 31 that electrically connect each battery stack 30A of the energy storage module 30 are connected to the rear wall 32B of the junction box 32. Therefore, the thermal influence from the junction box 32 on the busbars 31 can be reduced, and the thermal influence from the busbars 31 on the junction box 32 can also be reduced. 【0058】 Furthermore, a first space S1 (floor tunnel section 12A) extending in the front-rear direction is provided on the upper side of the case 22, and a second space S2 is provided on the upper side of the junction box 32 inside the case 22 and below the first space S1 when viewed from the rear. Here, it is known that high-temperature air from the exhaust pipe 14 can easily flow into the floor tunnel section 12A (first space S1). 【0059】 Therefore, compared to a case where the second space S2 is not provided, for example, where another electronic device is placed in the second space S2, the heat dissipation performance of the junction box 32 (indicated by arrow H3 in Figure 2) can be improved, heat diffusion to the surroundings can be reduced, and furthermore, thermal influence on the other electronic device can be prevented. In addition, the thermal influence on the junction box 32 from the first space S1 (indicated by arrow H2 in Figure 2) can also be reduced. 【0060】 Furthermore, within the case 22, a detector 50 for detecting voltage abnormalities in the energy storage module 30 is provided on the right side (outward in the vehicle width direction) of the junction box 32 and in front of the energy storage module 30. The wiring 56 connected to each battery stack 30A of the energy storage module 30 is connected to the rear wall 52B side of the case 52 of the detector 50. Therefore, in a plan view, the wiring 56 connecting the detector 50 and each battery stack 30A does not need to overlap with the junction box 32, and the thermal influence of the junction box 32 on the wiring 56 can be reduced. 【0061】Furthermore, the detector 50 is positioned at a predetermined distance from the lower wall 24D and upper wall 26U of the case 22. Therefore, compared to the case where the detector 50 is positioned close to the lower wall 24D or upper wall 26U of the case 22, the thermal influence on the detector 50 from the lower wall 24D (road surface) (indicated by arrow H4 in Figure 2) and the thermal influence on the upper wall 26U (first space S1) (indicated by arrow H2 in Figure 2) can be reduced. 【0062】 Furthermore, since the detector 50 is positioned to the right of the junction box 32 (outward in the vehicle width direction), the thermal influence from the junction box 32 on the detector 50 can be reduced. In addition, since an insulator 16 is interposed between the detector 50 and the exhaust pipe 14 in addition to the lower peripheral wall 24A of the case 22, the thermal influence from the exhaust pipe 14 on the detector 50 can also be reduced by the insulator 16. 【0063】 <Second Embodiment> Next, a second embodiment will be described. Note that parts equivalent to those in the first embodiment will be denoted by the same reference numerals, and detailed descriptions (including common functions) will be omitted as appropriate. 【0064】 As shown in Figure 4, in this second embodiment of the vehicle 10, the only difference from the first embodiment is the installation position of the detector 50. That is, in this second embodiment, the detector 50 is installed on the upper wall 32U of the right side portion of the junction box 32. Specifically, the upper ends of a pair of left and right legs 58 are attached to the outer side in the vehicle width direction on the lower surface of the detector 50 case 52, and the lower ends of these legs 58 are attached to the upper wall 32U of the junction box 32. 【0065】 As a result, the detector 50 is positioned on the upper wall 32U of the junction box 32 with a predetermined gap between them. This configuration is only applicable when the heat resistance temperature of the detector 50 is high or when the ambient temperature around the detector 50 does not rise to below the allowable temperature. In this case as well, it is preferable that the detector 50 has a predetermined gap between it and the upper wall 26U of the case 22. 【0066】 According to this second embodiment, the spatial efficiency within the case 22 can be improved and the size of the case 22 in the vehicle width direction can be reduced compared to the first embodiment in which the detector 50 is located on the outside of the junction box 32 in the vehicle width direction. Therefore, the energy storage device 20 can be miniaturized. 【0067】 Furthermore, since a predetermined gap is formed between the detector 50 and the upper wall 32U of the junction box 32 by the legs 58, the thermal influence from the junction box 32 on the detector 50 can be reduced compared to the case where the detector 50 case 52 is directly placed on the upper wall 32U of the junction box 32. 【0068】 The vehicle 10 according to this embodiment has been described above based on the drawings, but the vehicle 10 according to this embodiment is not limited to the illustrated version and can be modified as appropriate without departing from the gist of this disclosure. For example, in Figures 2 and 4, the energy storage module 30 is shown in a simplified form, and the shape and number of battery stacks 30A are not limited to the illustrated shape and number. Therefore, the cooling pipes 36 can also be appropriately routed, for example, in a meandering manner, depending on the number of battery stacks 30A. Furthermore, the cooling pipes 36 may be provided in a manner that does not contact the case 22.
