[0027] <3. Module base> 2 is a side view for explaining the power supply module 100. The power supply module 100 has a module base 110. The module base 110 is a support member that supports various components included in the power supply module 100.

[0028] The module base 110 includes at least one of one or more housings and one or more base members. In this embodiment, an example in which the module base 110 is formed by one case 111 will be described. The case 111 is an example of a "housing".

[0029] In this embodiment, the case 111 is formed in a box shape and has, for example, an upper wall 111a, a lower wall 111b, a front wall 111c, a rear wall 111d, a left wall 111e (see FIG. 1), and a right wall 111f (see FIG. 1).

[0030] The upper wall 111a is a wall portion that extends along the horizontal direction. The lower wall 111b is a wall portion that extends along the horizontal direction, similar to the upper wall 111a. The lower wall 111b is located below the upper wall 111a with a storage space between them. The front wall 111c is a wall portion that extends along the vertical and left-right directions. The front wall 111c connects the front end of the upper wall 111a to the front end of the lower wall 111b.

The left wall 111e is a wall portion that extends along the vertical and front-rear directions. The left wall 111e connects the left end of the upper wall 111a to the left end of the lower wall 111b. The right wall 111f is a wall portion that extends along the vertical and front-rear directions. The right wall 111f connects the right end of the upper wall 111a to the right end of the lower wall 111b.

[0031] However, one or more of the upper wall 111a, the lower wall 111b, the front wall 111c, the rear wall 111d, the left wall 111e, and the right wall 111f may be omitted. In this application, the term "housing body" refers to a member that covers the components arranged inside the housing body from two or more directions (e.g., three or more directions). A frame body that does not have the upper wall 111a and the lower wall 111b, and a U-shaped member that does not have the upper wall 111a, the lower wall 111b, and the rear wall 111d are each an example of the "housing body".

[0032] As shown in FIG. 2, the case 111 (module base 110) is disposed under the floor of the vehicle V. For example, the vehicle V has a floor member 3a that defines the floor surface of the vehicle interior 3. The case 111 (module base 110) is disposed below the floor member 3a. In this embodiment, the length L1 of the case 111 (module base 110) in the front-rear direction is smaller than the distance L2 between the front wheels 2A and the rear wheels 2B.

[0033] As shown in FIG. 1, case 111 (module base 110) has a front end 110a, a rear end 110b, a left end 110c, and a right end 110d.

[0034] When the vehicle V is viewed from above, the front end 110a is disposed between the center C1 in the fore-and-aft direction of the vehicle V and the front end Ea of the vehicle V. When the case 111 (module base 110) is divided into four areas in the fore-and-aft direction of the vehicle V, the front end 110a is the frontmost area among the four divided areas. When the vehicle V is viewed from above, the rear end 110b is disposed between the center C1 in the fore-and-aft direction of the vehicle V and the rear end Eb of the vehicle V. When the case 111 (module base 110) is divided into four areas in the fore-and-aft direction of the vehicle V, the rear end 110b is the rearmost area among the four divided areas.

[0035] When the vehicle V is viewed from above, the left end 110c is disposed between the center C2 of the vehicle V in the width direction and the left end Ec of the vehicle V. When the case 111 (module base 110) is divided into four regions in the width direction of the vehicle V, the left end 110c is the leftmost region among the four divided regions. When the vehicle V is viewed from above, the right end 110d is disposed between the center C2 of the vehicle V in the width direction and the right end Ed of the vehicle V. When the case 111 (module base 110) is divided into four regions in the width direction of the vehicle V, the right end 110d is the rightmost region among the four divided regions.

[0036] The case 111 is made of, for example, metal. The case 111 is electrically connected to the ground of the vehicle V. By being electrically connected to the ground, the case 111 functions as an EMI (Electromagnetic Interference) countermeasure component for the components included in the power supply module 100.

[0038] The high-voltage battery 120, the low-voltage battery 130, the inverter assembly 140, the power distribution unit 150, the ECU unit 160, and the control device 170 are supported by the module base 110. In this embodiment, the high-voltage battery 120, the low-voltage battery 130, the inverter assembly 140, the power distribution unit 150, the ECU unit 160, and the control device 170 are housed in one case 111.

[0039] <4.1 High-voltage battery> The high-voltage battery 120 is a battery capable of supplying high-voltage power of 100 V or more (e.g., 350 V). The high-voltage battery 120 is formed, for example, by electrically connecting a plurality of battery cells in series or in parallel. The high-voltage battery 120 is an example of a "first battery."

[0040] <4.2 Low voltage battery> The low-voltage battery 130 is a battery capable of supplying low-voltage power of less than 100 V (for example, 12 V). The low-voltage battery 130 is formed, for example, by electrically connecting a plurality of battery cells in series or in parallel. The low-voltage battery 130 is an example of a "second battery."

[0041] <4.3 Inverter assembly> The inverter assembly 140 is a functional unit that converts the power supplied from the high-voltage battery 120. The inverter assembly 140 is an example of a “power conversion unit.” The inverter assembly 140 includes, for example, a DC-DC converter 141, a motor inverter 142, a heat pump inverter 143, and a charger converter 144.

[0042] However, the "power conversion unit" in this application may have at least one of the following functions: converting DC power supplied from a battery into AC power, and converting DC power supplied from a battery into another DC power with a different voltage (stepped-up or stepped-down DC power). The "power conversion unit" in this application may be realized by at least one of the DC-DC converter 141, the motor inverter 142, the heat pump inverter 143, and the charger converter 144.

[0043] (DC-DC converter) The DC-DC converter 141 is a power conversion device that converts DC power of a certain voltage supplied from the high-voltage battery 120 into DC power of a lower voltage than the above voltage. For example, the DC-DC converter 141 converts high-voltage DC power supplied from the high-voltage battery 120 into low-voltage DC power. In this embodiment, the DC-DC converter 141 converts the high-voltage DC power supplied from the high-voltage battery 120 into two or more types of low-voltage DC power (for example, 12V DC power and 5V DC power). The DC-DC converter 141 outputs the obtained low-voltage DC power to the power distribution unit 150. The DC-DC converter 141 is an example of a "first power conversion device".

[0044] (Motor inverter) The motor inverter 142 is a power conversion device that converts DC power supplied from the high-voltage battery 120 into AC power (e.g., three-phase AC). For example, the motor inverter 142 converts high-voltage DC power supplied from the high-voltage battery 120 into high-voltage AC power. The motor inverter 142 outputs the obtained AC power to the motor 10 via a high-voltage connector 181, which will be described later. The motor inverter 142 is an example of a "second power conversion device."

[0045] (Heat pump inverter) The heat pump inverter 143 is a power conversion device that converts DC power supplied from the high-voltage battery 120 into AC power (e.g., single-phase AC). For example, the heat pump inverter 143 converts high-voltage DC power supplied from the high-voltage battery 120 into high-voltage AC power. The heat pump inverter 143 outputs the obtained AC power to the heat pump 21 via a high-voltage connector 182 described later. The heat pump inverter 143 is another example of a "second power conversion device."

[0046] (Charger Converter) The charger converter 144 is a power conversion device that converts AC power for charging, which is supplied from the outside, into DC power. For example, the charger converter 144 is electrically connected to the charging port 41 via a high-voltage connector 183, which will be described later. The charger converter 144 converts high-voltage AC power, which is supplied from the outside through the charging port 41 and the high-voltage connector 183, into high-voltage DC power. The charger converter 144 outputs the obtained DC power to the high-voltage battery 120.

[0047] <4.4 Power distribution unit> The power distribution unit 150 is a distribution device that distributes and supplies the electric power supplied to the power distribution unit 150 to a plurality of loads (and / or a plurality of loads) of the vehicle V. In this embodiment, the power distribution unit 150 distributes and supplies the low-voltage DC power supplied from the DC-DC converter 141 to a plurality of loads (for example, the front accessories 22L, 22R, the panel accessories 23, the door accessories 31AL, 31BL, 31AR, 31BR, the floor accessories 32FA, 32FB, the rear accessories 42L, 42R, the ECU unit 160, and the control device 170).

[0048] In this embodiment, the power distribution unit 150 is connected to the low-voltage battery 130. For example, when an abnormality occurs in the high-voltage battery 120 or the DC-DC converter 141, the power distribution unit 150 distributes and supplies the low-voltage DC power supplied from the low-voltage battery 130 to at least some of the multiple loads. Also, for example, at the time of startup before the vehicle V starts to be driven, the power distribution unit 150 distributes and supplies the low-voltage DC power supplied from the low-voltage battery 130 to at least some of the multiple loads.

[0049] In this embodiment, the power distribution unit 150 supplies a portion of the distributed power to the front auxiliary devices 22 through a low-voltage connector 191, which will be described later. The power distribution unit 150 supplies a portion of the distributed power to the panel auxiliary devices 23 through a low-voltage connector 192, which will be described later. The power distribution unit 150 supplies a portion of the distributed power to the door auxiliary devices 31 through a low-voltage connector 193 (or a low-voltage connector 191, see FIG. 1), which will be described later. The power distribution unit 150 supplies a portion of the distributed power to the floor auxiliary devices 32 through a low-voltage connector 194, which will be described later.

[0086] <7. Advantages>

[0087] As a comparative example, consider a power supply system including a battery placed under the floor and a power conversion unit that converts the power supplied from the battery. In this comparative example, the power conversion unit is placed in the front of the vehicle. In the configuration of this comparative example, in addition to wiring materials that connect the battery placed under the floor and the power conversion unit placed in the front of the vehicle, long wiring materials are required that connect each part of the vehicle, including the rear part of the vehicle, to the front part of the vehicle.

[0088] On the other hand, in this embodiment, the power supply module 100 includes a module base 110 arranged under the floor of the vehicle V, a power conversion unit supported by the module base 110, a first connector supported by the module base 110, and a second connector supported by the module base 110. A wiring material 200 that supplies a first power output from the power conversion unit to a first load unit can be connected to the first connector. A wiring material 200 that supplies a second power output from the power conversion unit to a second load unit can be connected to the second connector.

[0089] According to this configuration, the length of the first wiring material can be shortened to a length that connects the first load section and the first connector arranged under the floor of the vehicle. Also, the length of the second wiring material can be shortened to a length that connects the second load section and the second connector arranged under the floor of the vehicle. Therefore, the length of the wiring material can be shortened. Also, according to the above configuration, it is possible to avoid a large variation in the length of the first wiring material and the length of the second wiring material. If the variation in the length of multiple wiring materials can be reduced, the assembling of the wiring material to the vehicle V can be improved. Also, if the wiring material that crosses the underfloor by a large amount can be eliminated or reduced, the space for the wiring material formed under the floor can be reduced. If the space for the wiring material can be reduced, the space inside the vehicle V can be increased.

[0090] From another perspective, by having a module base 110 placed under the floor of the vehicle V, and a power conversion unit, a first connector, and a second connector each supported by the module base 110, a versatile power source sharing module 100 can be provided that is easily compatible with a variety of vehicle types.

[0091] 6, the power distribution units 151-155 are dispersedly arranged inside the case 111. With this configuration, the power distribution units 151-155, which are heat-generating components, are dispersedly arranged, so that it is possible to prevent heat from concentrating in a certain area. As a result, it is possible to thin the wiring material, which has been made thick as a countermeasure against heat.

[0092] Second embodiment Next, a second embodiment will be described. The second embodiment differs from the first embodiment in that at least a part of the high voltage battery 120 is detachably attached to the power supply module 100. Note that the configuration other than that described below is the same as that of the first embodiment.

[0093] 8 is a diagram showing an example of the configuration of a power supply module 100 according to the second embodiment. In this embodiment, a case 111 houses a low-voltage battery 130, an inverter assembly 140, a power distribution unit 150, an ECU unit 160, and a control device 170.

[0094] Meanwhile, each of the first battery unit 121 and the second battery unit 122 is housed in a case 112. The case 112 housing the first battery unit 121 or the second battery unit 122 is detachably attached to the power supply module 100. When the remaining capacity of the first battery unit 121 or the second battery unit 122 becomes low, the first battery unit 121 or the second battery unit 122 is removed from the power supply module 100 together with the case 112. Then, the charged first battery unit 121 or the second battery unit is attached to the power supply module 100 together with the case 112. With such a configuration, the length of the wiring material can be shortened.

[0095] Third embodiment Next, a third embodiment will be described. The third embodiment differs from the first embodiment in that the module base 110 is formed by a plurality of cases 301, 302. Note that the configuration other than that described below is the same as that of the first embodiment.

The plurality of cases 301, 302 are arranged under the floor of a vehicle V, for example, lined up in the horizontal direction.

As shown in Fig. 10, in this embodiment, a module base 110 is formed by one or more (for example, a plurality) base members 401, 402. Each of the base members 401, 402 is a plate-shaped member. Each of the base members 401, 402 may be a plate material made of metal or synthetic resin, or may be a board on which an electric circuit is formed. The base members 401, 402 are arranged, for example, horizontally side by side under the floor of the vehicle V.

[0100] The high voltage battery 120, the low voltage battery 130, the DC-DC converter 141, the motor inverter 142, the heat pump inverter 143, the charger converter 144, the power distribution unit 150, the ECU unit 160, and the control device 170 are mounted on one or more (e.g., a plurality of) base members 401, 402. Even with this configuration, the length of the wiring material can be shortened.

[0101] Some embodiments have been described above. However, the embodiments are not limited to the above examples. For example, some of the above embodiments may be realized in combination with each other.

[0102] <Additional Notes> Some power supply modules are listed below.

[0103] [1] A module base (e.g., module base 110) disposed under the floor of a vehicle; a power conversion unit (e.g., an inverter assembly 140, a DC-DC converter 141, or a motor inverter 142) that is supported by the module base and converts power supplied from a battery (e.g., a high-voltage battery 120); a first connector (e.g., any one of high-voltage connectors 181A, 181B, 182, 183 and low-voltage connectors 191L, 191R, 192, 193L, 193R, 194, 195L, 195R) supported by the module base and to which a first wiring material (e.g., wiring material 200) can be connected, the first wiring material (e.g., any one of front motor 10A, rear motor 10B, heat pump 21, left front auxiliary equipment 22L, right front auxiliary equipment 22R, panel auxiliary equipment 23, first to fourth door auxiliary equipment 31AL, 31BL, 31AR, 31BR, first and second floor auxiliary equipment 32FA, 32FB, left rear auxiliary equipment 42L, and right rear auxiliary equipment 42R) can be connected, a second connector (e.g., any other one of high-voltage connectors 181A, 181B, 182, 183 and low-voltage connectors 191L, 191R, 192, 193L, 193R, 194, 195L, 195R) supported by the module base and to which a second wiring material (e.g., wiring material 200) can be connected, the second wiring material (e.g., wiring material 200) supplies a second electric power output from the electric power conversion unit to a second load unit of the vehicle (e.g., any other one of front motor 10A, rear motor 10B, heat pump 21, left front auxiliary equipment 22L, right front auxiliary equipment 22R, panel auxiliary equipment 23, first to fourth door auxiliary equipment 31AL, 31BL, 31AR, 31BR, first and second floor auxiliary equipment 32FA, 32FB, left rear auxiliary equipment 42L, right rear auxiliary equipment 42R); A power supply module comprising: The first power and the second power may have the same voltage or different voltages, and the first power and the second power may both be DC power or both be AC ​​power.

[0104] According to the configuration [1], the length of the first wiring material can be shortened to a length that connects the first load section and the first connector arranged under the floor of the vehicle. Also, the length of the second wiring material can be shortened to a length that connects the second load section and the second connector arranged under the floor of the vehicle. Therefore, the length of the wiring material can be shortened.

[0105] [2]. The power supply module according to [1], The module base includes a housing (e.g., case 111) placed under the floor of the vehicle, the battery and the power conversion unit are housed in the housing, and the first connector and the second connector are supported by the housing.

[0106] According to the configuration of [2] above, since the battery and the power conversion unit are housed in one housing, the battery and the power conversion unit can be arranged closer to each other under the floor of the vehicle than when the battery and the power conversion unit are housed in separate housings. The configuration of the electrical connection member between the battery and the power conversion unit, which allows the battery and the power conversion unit to be arranged closer to each other, can be simplified. If the configuration of the electrical connection member can be simplified, it becomes easier to miniaturize the power supply module.

[0107] [3].The power supply module according to [1] or [2], The power conversion unit has a first power conversion device (e.g., DC-DC converter 141) that converts the power supplied from the battery into the first power, which is DC power, and a second power conversion device (e.g., motor inverter 142 or heat pump inverter 143) that converts the power supplied from the battery into the second power, which is AC power, and the first connector is a connector compatible with the AC power, and the second connector is a connector compatible with the AC power.

[0108] According to the configuration [3] above, it is possible to shorten the length of the wiring material both connected to the destination of the DC power supply and connected to the destination of the AC power supply.

[0109] [4].The power supply module according to [1] or [2], When the vehicle is viewed from above, the module base has a front end portion (e.g., front end portion 110a) that is located between the fore-and-aft center of the vehicle and the front end of the vehicle, and a rear end portion (e.g., rear end portion 110b) that is located between the fore-and-aft center of the vehicle and the rear end of the vehicle, the first connector being located at the front end portion, and the second connector being located at the rear end portion.

[0110] According to the configuration [4] above, the first connector and the second connector are arranged separately at both ends of the module base in the front-to-rear direction, thereby making it possible to further shorten the length of the first wiring material and the second wiring material.
