  Since the space formed below the seat is a limited space (dead space), it is necessary to efficiently arrange fans and the like.

  The present invention is a temperature adjustment structure for adjusting the temperature of a power storage device by supplying air in a vehicle compartment to the power storage device, and includes a blower, an intake duct, and a bracket. The blower is arranged in a space formed between the floor panel of the vehicle and a seat positioned above the floor panel, and moves air toward the power storage device. The intake duct is disposed in the space and takes in air according to the drive of the blower. The bracket supports the air intake duct on the surface facing the seat and supports the blower on the surface facing the floor panel.

  The blower can be arranged at a position away from the floor panel. Thereby, even if liquids, such as water, permeate into a floor panel, it can control that a liquid reaches a blower.

  The bracket can be provided with legs that extend toward the floor panel. A cushion that contacts the floor panel can be provided at the tip of the leg. By using the legs, the blower can be supported at a position away from the floor panel. Further, by providing a cushion at the tip of the leg, the leg only needs to be disposed on the floor panel, and the vibration of the leg due to the vibration of the vehicle can be absorbed by the cushion. If the legs are simply arranged on the floor panel, the intake duct and the blower can be easily attached.

  The legs can be located behind the vehicle relative to the blower. The space formed below the seat may be accessed from the rear of the vehicle. For example, an occupant's foot may enter a space formed below the seat. Therefore, by arranging the leg portion behind the vehicle with respect to the blower, it is possible to prevent an external force from acting on the blower.

  A part of the bracket can be extended to the front of the vehicle, and this part can be fixed to a cross member protruding above the vehicle from the floor panel. The intake port of the intake duct can be opened toward the front of the vehicle.

  The blades provided in the blower can be rotated around a rotation axis extending in the vertical direction of the vehicle. The size of the blower is often the smallest in the direction in which the rotating shaft extends. Therefore, by setting the direction in which the rotation shaft extends to the vertical direction of the vehicle, the blower can be efficiently arranged in the space formed below the seat.

  The power storage device can be disposed between two seats adjacent in the left-right direction of the vehicle. Here, the blower and the intake duct can be arranged in a space corresponding to one of the two sheets. In this case, the air from the blower can be guided to the power storage device using another duct. A part of the other duct can be arranged in a space corresponding to one sheet. Thereby, the air taken in from the intake duct can be guided to the power storage device.

  According to the present invention, the intake duct and the blower can be supported by using the two surfaces of the bracket, and the intake duct and the blower can be arranged by using the bracket with respect to the space formed below the seat. . The air intake duct is disposed along the surface facing the seat, and the blower is disposed along the surface facing the floor panel. Therefore, the air intake duct and the blower are efficiently used for the space formed below the seat. It becomes easy to arrange well.

The arrow LH indicates the left direction when facing the forward direction of the vehicle. The relationship between the arrows FR, UP, RH, and LH is the same in other drawings.

  As shown in FIG. 1, a driver's seat 101 and a passenger seat 102 are provided in the vehicle interior, and the driver's seat 101 and the passenger seat 102 are fixed to the floor panel 103 via seat slides. The seat slide is used for sliding the driver's seat 101 and the passenger seat 102 in the front-rear direction of the vehicle.

  A first air intake duct 11 is disposed in a space formed between the driver's seat 101 (specifically, a seat cushion) and the floor panel 103. The first intake duct 11 is used for taking in air in the passenger compartment. As will be described later, a blower (not shown in FIG. 1) is disposed below the first intake duct 11, and air in the vehicle compartment is taken into the first intake duct 11 by driving the blower.

  The air taken in from the first intake duct 11 and passed through the blower is guided to the second intake duct 12. The second intake duct 12 is disposed in a space formed between the driver's seat 101 and the floor panel 103, and a part of the second intake duct 12 extends in the left-right direction of the vehicle.

For example, the first intake duct 11, the blower, and the second intake duct 12 can be disposed in a space formed between the passenger seat 102 (specifically, the seat cushion) and the floor panel 103.

  A battery pack 100 is disposed between the driver seat 101 and the passenger seat 102. A part of the second intake duct 12 is disposed along the bottom surface of the battery pack 100 and extends in the front-rear direction of the vehicle. Battery pack 100 outputs energy for running the vehicle. Specifically, the electrical energy output from the battery pack 100 is converted into kinetic energy for running the vehicle by a motor / generator.

  On the other hand, when the vehicle is decelerated or stopped, the motor / generator can convert kinetic energy generated during braking of the vehicle into electrical energy. The battery pack 100 can store electrical energy generated by the motor / generator. A DC / DC converter and an inverter can be arranged between the battery pack 100 and the motor / generator.

  If the DC / DC converter is used, the output voltage of the battery pack 100 can be boosted and supplied to the motor / generator, or the output voltage from the motor / generator can be stepped down and supplied to the battery pack 100. If an inverter is used, an AC motor can be used as the motor / generator.

  In the present embodiment, the battery pack 100 is disposed in the vehicle interior, but is not limited thereto. Specifically, the battery pack 100 can be disposed outside the passenger compartment.

  As shown in FIG. 2, the battery pack 100 includes a case 200 that forms the exterior of the battery pack 100.

  The case 200 houses a lower battery stack 210 and an upper battery stack 220, and the battery stacks 210 and 220 are arranged in the vertical direction of the vehicle. The lower battery stack 210 has a plurality of single cells 211 arranged side by side in the front-rear direction of the vehicle. The plurality of single cells 211 are electrically connected in series by a bus bar (not shown). A space is formed between two unit cells 211 that are adjacent to each other in the front-rear direction of the vehicle, and this space is a space in which air (air in the vehicle interior) used to adjust the temperature of the unit cell 211 moves. .

  The upper battery stack 220 and the lower battery stack 210 are arranged in the vertical direction of the vehicle, and a pedestal (not shown) that supports the upper battery stack 220 is disposed between the lower battery stack 210 and the upper battery stack 220. ing.

  The upper battery stack 220 includes a plurality of unit cells 221 arranged side by side in the front-rear direction of the vehicle. The plurality of single cells 221 are electrically connected in series by a bus bar (not shown). A space is formed between two unit cells 221 adjacent to each other in the front-rear direction of the vehicle, and this space is a space in which air (air in the vehicle interior) used to adjust the temperature of the unit cell 221 moves. .

  The lower battery stack 210 and the upper battery stack 220 are electrically connected in series via an electric cable. In the present embodiment, the lower battery stack 210 and the upper battery stack 220 are electrically connected in series. However, the lower battery stack 210 and the upper battery stack 220 may be electrically connected in parallel.

  In the present embodiment, the lower battery stack 210 and the upper battery stack 220 have the same structure. That is, the number of the single cells 211 constituting the lower battery stack 210 is equal to the number of the single cells 221 constituting the upper battery stack 220. The number of the single cells 211 and 221 constituting the battery stacks 210 and 220 can be appropriately set based on the required output of the battery pack 100 and the like.

  In addition, the number of the single cells 211 and 221 constituting the battery stacks 210 and 220 can be different from each other. In the present embodiment, the two battery stacks 210 and 220 are arranged in the vertical direction of the vehicle, but three or more battery stacks can be arranged in the vertical direction of the vehicle. Further, only one battery stack may be arranged.

  As the single cells 211 and 221, a secondary battery such as a nickel metal hydride battery or a lithium ion battery can be used. An electric double layer capacitor (capacitor) can be used instead of the secondary battery. In this embodiment, the plurality of single cells 211 (221) are arranged in one direction, but the present invention is not limited to this. Specifically, one battery module can be constituted by a plurality of single cells 211 (221), and the plurality of battery modules can be arranged in one direction.

  As shown in FIG. 1, the case 200 houses a first intake chamber 31 and a second intake chamber 32. The first intake chamber 31 and the second intake chamber 32 extend in the front-rear direction of the vehicle and are fixed to the case 200. The first intake chamber 31 and the second intake chamber 32 are arranged in the vertical direction of the vehicle.

  The first intake chamber 31 and the second intake chamber 32 are connected to the third intake duct 20, and the air from the third intake duct 20 is guided to the first intake chamber 31 and the second intake chamber 32. The third intake duct 20 extends in the vertical direction of the vehicle and is accommodated in the case 200.

  The air that has moved through the first intake chamber 31 is guided to the lower battery stack 210. The air from the first intake chamber 31 exchanges heat with the unit cells 211 while moving in a space formed between two unit cells 211 adjacent in the front-rear direction of the vehicle. The air that has moved through the second intake chamber 32 is guided to the upper battery stack 220. The air from the second intake chamber 32 exchanges heat with the unit cells 221 while moving in a space formed between two unit cells 221 adjacent in the longitudinal direction of the vehicle.

  By causing heat exchange between the air and the single cells 211 and 221, the temperature of the single cells 211 and 221 can be adjusted. For example, when the unit cells 211 and 221 generate heat by charging and discharging, the temperature rise of the unit cells 211 and 221 can be suppressed by bringing cooling air into contact with the unit cells 211 and 221.

  Moreover, when the single cells 211 and 221 are excessively cooled, the single cells 211 and 221 can be warmed by bringing heating air into contact with the single cells 211 and 221. The temperature of the air in the passenger compartment may be adjusted by an air conditioner mounted on the vehicle, and the air in the passenger compartment is suitable for temperature adjustment of the single cells 211 and 221.

  In the lower battery stack 210, the air that has passed between two unit cells 211 adjacent in the front-rear direction of the vehicle, in other words, the air after heat exchange moves to the first exhaust chamber 41. In the upper battery stack 220, the air that has passed between two unit cells 221 adjacent in the front-rear direction of the vehicle, in other words, the air after heat exchange moves to the second exhaust chamber 42. The first exhaust chamber 41 and the second exhaust chamber 42 extend in the front-rear direction of the vehicle and are aligned in the vertical direction of the vehicle.

The first intake chamber 31 and the first exhaust chamber 41 are arranged at positions sandwiching the lower battery stack 210 in the left-right direction of the vehicle. The second intake chamber 32 and the second exhaust chamber 42 are disposed at positions sandwiching the upper battery stack 220 in the left-right direction of the vehicle.

  Air moving through the first exhaust chamber 41 and the second exhaust chamber 42 is guided to the exhaust duct 50. The exhaust duct 50 branches off from the first exhaust chamber 41 and the second exhaust chamber 42 and takes in air from the first exhaust chamber 41 and the second exhaust chamber 42. The exhaust duct 50 is accommodated in the case 200. Further, a part of the exhaust duct 50 extends in the vertical direction of the vehicle, and the exhaust duct 50 is aligned with the third intake duct 20 in the horizontal direction of the vehicle.

  The air guided to the exhaust duct 50 moves toward the floor panel 103 while moving along the exhaust duct 50. The air discharged from the exhaust duct 50 is diffused along the upper surface of the floor panel 103. The upper surface of the floor panel 103 is covered with a carpet, and the air discharged from the exhaust duct 50 diffuses while moving between the floor panel 103 and the carpet.

  In the present embodiment, the third intake duct 20 and the exhaust duct 50 are arranged on the rear side of the vehicle with respect to the battery stacks 210 and 220, but this is not restrictive. For example, the third intake duct 20 and the exhaust duct 50 can be arranged on the front side of the vehicle with respect to the battery stacks 210 and 220.

  Further, one of the third intake duct 20 and the exhaust duct 50 is disposed on the rear side of the vehicle with respect to the battery stacks 210 and 220, and the other of the third intake duct 20 and the exhaust duct 50 is connected to the battery stacks 210 and 220. However, it can also be arranged on the front side of the vehicle.
