[0002] When a user gets into an electric vehicle equipped with a battery and starts driving, it is desirable that not only the battery be charged but also the interior of the vehicle be air-conditioned to a temperature comfortable for the user. Therefore, by operating the on-board air conditioner while the battery is being charged, the interior of the vehicle will be at an appropriate temperature when charging is complete, allowing the user to get in immediately and start driving comfortably (see Patent Document 1).

[0003] However, the battery of an electric vehicle is used as a power source both for driving the electric vehicle and for driving the on-board air conditioner that conditions the interior of the electric vehicle. Therefore, if the on-board air conditioner is operated while the battery is being charged, some of the power is consumed by the on-board air conditioner, reducing the power used to charge the battery, and it takes longer to charge the battery than if the on-board air conditioner was not operating.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] Hereinafter, exemplary embodiments of a power supply facility for an electric vehicle, which is an electrically powered vehicle, will be described with reference to the drawings. The power supply facility described in the following embodiments is a facility that supplies power to a battery of the electric vehicle in a wireless manner.

[0020] First Embodiment Configuration of power supply equipment according to the first embodiment The configuration of the power supply facility for an electric vehicle of this embodiment will be described with reference to Figures 1(a), (b) and 2. Figure 1(a) is a schematic diagram of a power supply facility 100A according to this embodiment and an electric vehicle 300A that uses the power supply facility 100A, as seen from the side (however, the side of the power supply facility 100A is not shown), and Figure 1(b) is a schematic diagram of the inside of the power supply facility 100A as seen from above. Figure 2 is a block diagram showing the configuration of the power supply facility 100A.

[0021] 1(a) and 1(b), the power supply facility 100A is provided in a building X having a size (width, length, and height) sufficient to accommodate an electric vehicle 300A to be supplied with power. This building X may be provided outdoors, in a large warehouse, or in a space with a roof but no walls, such as a large self-driving car park having multiple floors. A power supply space SP is provided in this building X, where the electric vehicle 300A is parked and power is supplied, and a white line L is marked on the floor corresponding to the power supply space SP as a marker for the electric vehicle 300A to be supplied with power as a parking position target.

[0022] In addition, an opening (not shown) large enough for the electric vehicle 300A to pass through is formed at the entrance of the building X, and an entrance door ET is installed as an automatic door for opening and closing the opening. In addition, an opening (not shown) large enough for the electric vehicle 300A to pass through is formed at the exit of the building X, and an exit door EX is installed as an automatic door for opening and closing the opening. These entrance doors ET and exit doors EX are configured to be automatically opened and closed without any human intervention by means of electric power or pneumatic or hydraulic power. In addition, the walls and ceiling of the building X are highly insulated, for example, by having glass wool attached to the entire surface, and when the entrance door ET and exit door EX are closed, the amount of air flowing in and out between the space inside the building X and the outside space is reduced, and the space becomes closed and insulated, allowing the temperature inside to be controlled by a building air conditioner described later. In the building X, the electric vehicle 300A moves by an automatic parking function, as described later, so no humans get on or off. Therefore, when the electric vehicle 300A is parked, there needs to be a gap between the electric vehicle 300A and the building X that allows the electric vehicle 300A to move for automatic parking (a gap that prevents the outer surface of the body of the electric vehicle 300A from colliding with or rubbing against the inner surface of the building X during movement for automatic parking), and there is no need for a space for a person to enter or a space for opening the door of the electric vehicle 300A. Note that one or both of the entrance door ET and the exit door EX may be of other shapes and forms as long as they can be opened and closed automatically without any person present. For example, they may be shutters that move electrically in the vertical direction.

[0023] In the building X, there are installed a power supply device 11, a building air conditioner 12, a lighting device 13, an entrance door drive device 14, an exit door drive device 15, an outdoor wireless communication device 16, an indoor wireless communication device 17, and a power supply controller 18 as devices that constitute the power supply facility 100A. These devices 11 to 18 are operated by a power source 200. The power source 200 is, for example, a commercial power source sent from a power plant, a solar power generation device, a wind power generation device, or a fuel cell. The functions of these devices 11 to 18 will be described with reference to FIG. 2.

[0024] The power supply device 11 is a power transmission device installed in the power supply space SP, and includes a conversion circuit 111 and a power transmission coil 112. The conversion circuit 111 converts the power supplied from the power source 200 into high-frequency (for example, 100 kHz) AC power. The power transmission coil 112 is magnetically coupled to a power receiving coil of a power receiving device mounted on the electric vehicle 300A to be supplied with power, and supplies the converted AC power in a non-contact manner. The power transmission coil 112 is installed on the floor of the building X, at a position several centimeters higher than the floor, or at a position embedded below the floor. The non-contact power supply method implemented by the power supply device 11 may be a magnetic resonance method, an electric field method (in the case of the electric field method, the power transmission coil and the power receiving coil are coupled by an electric field), or the like, and is not particularly limited as long as it is a method that can supply power to the battery of the electric vehicle 300A.

[0025] The building air conditioner 12 is installed on a side wall or ceiling of the building X, and conditions the air inside the building X based on the operating state of the power supply device 11. The lighting device 13 illuminates the inside of the building X. The entrance door drive device 14 drives the opening and closing operation of the entrance door ET. The exit door drive device 15 drives the opening and closing operation of the exit door EX.

[0026] The outdoor wireless communication device 16 is installed outside the building X (it may be in contact with the outer surface of the building X, or may be supported by a pillar and separated from the outer surface of the building X), and performs wireless communication with the electric vehicle 300A located outside the building X. The indoor wireless communication device 17 is installed inside the building X, and performs wireless communication with the electric vehicle 300A located inside the building X. In the present embodiment, a case has been described in which two wireless communication devices, the outdoor wireless communication device 16 and the indoor wireless communication device 17, are installed in the building X, but the number is not limited to this, and one wireless communication device capable of communicating both indoors and outdoors may be installed in the building X. Furthermore, when the building X is large, three or more wireless communication devices may be installed in order to include areas other than the power supply space SP in the building X through which the electric vehicle 300A passes as a wireless communication target area.

[0027] The power supply controller 18 has a vehicle entrance / exit control unit 181, a power transmission control unit 182, and a building air conditioning control unit 183. When the electric vehicle 300A to be supplied with power enters the building X, the vehicle entrance / exit control unit 181 opens the entrance door ET using the entrance door drive device 14 and turns on the lighting device 13, and after the electric vehicle 300A enters, closes the entrance door ET and turns off the lighting device 13. In addition, when the electric vehicle 300A exits the building X, the vehicle entrance / exit control unit 181 opens the exit door EX using the exit door drive device 15, and closes it after the electric vehicle 300A exits.

[0028] When the electric vehicle 300A to be supplied with power enters and parks in the power supply space SP, the power transmission control unit 182 causes the power supply device 11 to transmit power to the electric vehicle 300A. The building air conditioning control unit 183 causes the building air conditioner 12 to perform air conditioning at a predetermined timing while the electric vehicle 300A is being supplied with power.

[0029] <Configuration of an electric vehicle using the power supply equipment 100A> The configuration of an electric vehicle 300A using the power supply facility 100A will be described with reference to the block diagram of FIG. 3. The electric vehicle 300A includes a power receiving device 31, a battery 32, an in-vehicle wireless communication device 33, a human presence sensor 34, an in-vehicle air conditioner 35, an automatic parking mechanism 36, a marker recognition unit 37, and a vehicle controller 38. The battery 32, the power receiving device 31, and the in-vehicle air conditioner 35 are connected via a power bus 39. The vehicle controller 38, the in-vehicle wireless communication device 33, the human presence sensor 34, the in-vehicle air conditioner 35, the automatic parking mechanism 36, and the marker recognition unit 37 are each communicatively connected via a communication line or wireless communication. The communication lines may be provided independently for each communication connection, or, for example, all devices may be communicatively connected via a common communication cable, such as a wired LAN, and the communication partner may be identified by a communication protocol.

[0030] The power receiving device 31 has a power receiving coil 311, a rectifier 312, and a smoothing circuit 313. The power receiving coil 311 is provided on the underside of the electric vehicle 300A, and is magnetically coupled to the power transmitting coil 112 of the power supply device 11 to receive contactless power. The rectifier 312 rectifies the power received by the power receiving coil 311. The smoothing circuit 313 is composed of a capacitor and an inductor, and smoothes the power rectified by the rectifier 312 to output DC power.

[0031] The battery 32 is charged with DC power output from the power receiving device 31. The battery 32 also supplies power to the in-vehicle air conditioner 35 in the electric vehicle 300A via a power bus 39 by discharging the charged power. When the output voltage of the power receiving device 31 differs from the voltage of the battery 32, the voltage may be converted by a DC-DC converter (not shown). Note that, although power is supplied to the in-vehicle wireless communication device 33, the human sensor 34, the automatic parking mechanism 36, the marker recognition unit 37, and the vehicle controller 38, it may be supplied directly from the battery 32 or another battery (for example, a lead-acid battery that is a starter battery) or via a DC-DC converter that converts voltage, although this is not shown.

[0032] The in-vehicle wireless communication device 33 wirelessly communicates with the outdoor wireless communication device 16 and the indoor wireless communication device 17 of the power supply facility 100A. The human presence sensor 34 detects people inside the electric vehicle 300A using ultrasonic waves or a laser. The in-vehicle air conditioner 35 air-conditions the interior of the electric vehicle 300A. The automatic parking mechanism 36 has a function of driving the electric vehicle 300A unmanned and automatically parking it. The marker recognition unit 37 recognizes the position of a marker that is a target parking position for the electric vehicle 300A to be supplied with power in the building X. In this embodiment, the marker is a white line L marked on the floor of the building X, and the marker recognition unit 37 has a function of recognizing the position of the white line L by photographing an area including the white line L from a position outside the power supply space SP and analyzing the image information.

[0033] The vehicle controller 38 controls the in-vehicle wireless communication device 33, the human presence sensor 34, the in-vehicle air conditioner 35, the automatic parking mechanism 36, and the marker recognition unit 37. When controlling these devices 33 to 37, the vehicle controller 38 may transmit control commands by turning on / off electrical signals via wired communication, or may transmit control commands via wired or wireless communication.

[0034] <Operation when power supply equipment 100A according to the first embodiment supplies power to electric vehicle 300A> When the power supply facility 100A according to this embodiment supplies power to the electric vehicle 300A, the electric vehicle 300A stops in the disembarking area PA in front of the entrance to the building X shown in FIG. 4, all passengers disembark, and the vehicle door is closed. Then, the user performs a power supply execution operation. When the power supply execution operation is performed, a series of operations described below is started, and the power supply facility 100A supplies power to the electric vehicle 300A. The user only performs the power supply execution operation, and the series of operations following the power supply execution operation are performed automatically without requiring any operation by the user. The power supply execution operation is realized, for example, when the user presses a button on a wireless terminal such as a smartphone and sends a command to the vehicle controller 38 via the in-vehicle wireless communication device 33.

[0035] Operations executed by the power feeding controller 18 of the power feeding equipment 100A and the vehicle controller 38 of the electric vehicle 300A when a power feeding execution operation is performed will be described with reference to the flowcharts of FIGS. 5A and 5B.

[0036] When a power supply execution operation is performed by a user, the operation information is received by the vehicle controller 38 of the electric vehicle 300A. When the vehicle controller 38 receives the operation information of the power supply execution operation ("YES" in step S1), it determines whether or not there is a person inside the electric vehicle 300A based on the detection result by the human presence sensor 34 (step S2). If it determines that there is a person inside the vehicle ("YES" in step S2), it waits until there is no person inside the vehicle. If it determines that there is no person inside the vehicle ("NO" in step S2), the vehicle controller 38 stops the in-vehicle air conditioner 35 (step S3).

[0037] Next, the vehicle controller 38 wirelessly transmits an entry request to the power supply controller 18 via the in-vehicle wireless communication device 33 (step S4). In the power supply controller 18, the vehicle entry / exit control unit 181 receives the entry request via the outdoor wireless communication device 16 (step S5), and determines whether the power supply space SP is vacant or not based on the detection result of a sensor (not shown) installed in the power supply space SP (step S6). Whether the power supply space SP is vacant or not can be determined, for example, by placing a laser curtain across the power supply space SP, and determining that the power supply space SP is vacant if the laser light is not blocked, and that the power supply space SP is not vacant if the laser light is blocked.

[0038] When it is determined that the power supply space SP is vacant ("YES" in step S6), the vehicle entry / exit control unit 181 drives the entrance door drive device 14 to open the entrance door ET and turns on the lighting device 13 (step S7). The vehicle entry / exit control unit 181 wirelessly transmits an entry permission notification to the vehicle controller 38 (step S8).

[0039] The electric vehicle 300A waits in the disembarking area PA until it receives an entry permission notice from the power supply controller 18. Then, when it receives the entry permission notice (step S9), the vehicle controller 38 requests the position information of the white line L from the marker recognition unit 37. When the position information of the white line L is requested, the marker recognition unit 37 recognizes the position of the white line L by capturing an image of the inside of the building X through the opening of the entrance door ET and analyzing the captured image information. At this time, since the lighting device 13 in the building X is turned on, the white line L is illuminated by the light from the lighting device 13, and the white line L can be clearly captured, and the position of the white line L can be clearly recognized by analyzing the captured image information. The marker recognition unit 37 sends the acquired position information of the white line L to the vehicle controller 38.

[0040] When the vehicle controller 38 acquires the position information of the white line L, the vehicle controller 38 determines the parking position of the electric vehicle 300A relative to the white line L based on the position of the power receiving device 31 in the vehicle body so as to align the power receiving device 31 with the position of the power supply device 11 in the power supply space SP. For example, it is assumed that the white line L is provided at a position a first predetermined distance forward from the installation position of the power supply device 11 in the power supply space SP and at a position a second predetermined distance in the left-right direction. It is also assumed that the power receiving device 31 of the electric vehicle 300A is provided at the center in the left-right direction of the vehicle body and at a third predetermined distance from the front end of the vehicle body. In this case, the parking position is determined so that the center of the vehicle body of the electric vehicle 300A is aligned with the center line of the left and right white lines L and the front end of the vehicle body is located (first predetermined distance-third predetermined distance) in front of the front white line L, thereby aligning the power receiving device 31 of the electric vehicle 300A with the power supply device 11 in the power supply space SP.

[0041] When the vehicle controller 38 determines the parking position for the electric vehicle 300A, it sends a parking command to the automatic parking mechanism 36 to park the electric vehicle 300A at the determined position (step S10). Based on the received parking command, the automatic parking mechanism 36 automatically drives the electric vehicle 300A into the entrance opening of the building X, and parks the electric vehicle 300A at the determined parking position, aiming for the white line L.

[0042] When the electric vehicle 300A is parked in the parking position ("YES" in step S11), the power receiving device 31 faces the power supply device 11, enabling contactless power supply with high power supply efficiency. Furthermore, when the electric vehicle 300A is parked in the parking position, the vehicle controller 38 transmits an entry end notification to the power supply controller 18 (step S12). When the power supply controller 18 receives the entry end notification (step S13), the vehicle entry / exit control unit 181 drives the entrance door drive device 14 to close the entrance door ET and turns off the lighting device 13 (step S14).

[0043] Next, the power transmission control unit 182 of the power supply controller 18 instructs the power supply device 11 to transmit power (step S15). Based on the received instruction, the power supply device 11 starts contactless power transmission to the electric vehicle 300A. The power transmitted from the power supply device 11 is received by the power receiving device 31 of the electric vehicle 300A and is charged into the battery 32.

[0044] Here, if the in-vehicle air conditioner 35 is operated to maintain the interior temperature of the electric vehicle 300A at an appropriate temperature while the battery 32 is being charged, a part of the power received by the power receiving device 31 is consumed by the in-vehicle air conditioner 35, and the power used to charge the battery 32 is reduced. Therefore, the battery 32 is charged more slowly than when the in-vehicle air conditioner 35 is not operated, and the time until the battery 32 is fully charged increases. In this embodiment, since the in-vehicle air conditioner 35 is stopped, all of the power received by the power receiving device 31 is sent to the battery 32, the battery 32 is charged faster, and the time until the battery 32 is fully charged decreases.

[0045] When the power supply device 11 starts transmitting power to the electric vehicle 300A, the power transmission control unit 182 sets a scheduled exit time when the electric vehicle 300A will finish charging and exit from the building X (step S16). The scheduled exit time of the electric vehicle 300A is calculated by adding the current time and the required power supply time (U). The required power supply time (U) is, for example, an estimate of the time required to charge the battery 32 until it is fully charged (i.e., the charging rate is 100%) or until it reaches a predetermined charging rate (e.g., 80%) at the time when the power supply device 11 starts supplying power to the battery 32. Alternatively, if the use of the electric vehicle 300A is reserved for a predetermined time before the time indicated by the current time plus the required power supply time (U), the reserved time may be set as the scheduled exit time.

[0046] Here, the building air conditioning control unit 183 is preset with the air conditioning set temperature (D) and the building air conditioning time (T) of the building air conditioner 12. These values ​​are set so that the air in the building X, which has been conditioned by the building air conditioner 12, circulates through the electric vehicle 300A's ventilation openings or the like, to make the temperature inside the vehicle comfortable for humans. That is, when the building air conditioner 12 performs air conditioning operation at the air conditioning set temperature (D) for the building air conditioning time (T), the temperature inside the electric vehicle 300A becomes comfortable for humans. Then, when the building air conditioning control unit 183 recognizes that the current time is the building air conditioning time (T) before the scheduled departure time of the electric vehicle 300A that has been set ("YES" in step S17), it starts the air conditioning operation of the building air conditioner 12 at the air conditioning set temperature (D) (step S18).

[0047] This air conditioning set temperature (D) may be set higher than a temperature that is comfortable for humans when heating in winter and lower when cooling in summer, taking into consideration that the temperature inside the vehicle and the temperature outside the vehicle do not necessarily match because heat is transferred from the outside to the inside of the electric vehicle by air circulation, and that the temperature inside the vehicle changes due to the influence of the outside temperature when the electric vehicle leaves the power supply space SP. Also, the building air conditioning time (T) may be set to a different time depending on the outside temperature.

[0048] At this time, if the scheduled exit time is set to the reserved use time of electric vehicle 300A and the reserved use time is changed to a later time by the user while power is being supplied to battery 32, the scheduled exit time is also changed later accordingly. If building air conditioner 12 is not yet operating at the time of the change, the operation start time of building air conditioner 12 is also changed later to match the changed exit time. Controlled in this manner, unnecessarily operating building air conditioner 12 is prevented.

[0049] Furthermore, if the remaining time until the scheduled exit time is already equal to or less than the building air conditioning time (T) when the power transmission control unit 182 sets the scheduled exit time, the building air conditioning control unit 183 immediately operates the building air conditioner 12 upon starting power supply. Alternatively, if the required power supply time (U) is shorter than the building air conditioning time (T) when the power transmission control unit 182 sets the scheduled exit time, the time indicated by the current time + the building air conditioning time (T) may be set as the scheduled exit time in order to ensure time to bring the inside of the electric vehicle 300A to an appropriate temperature.

[0050] When the building air conditioner 12 operates at the air conditioning set temperature (D) for the building air conditioning time (T), the inside of the building X is air-conditioned, and air is circulated through the ventilation openings of the electric vehicle 300A, so that the temperature inside the electric vehicle 300A becomes a temperature at which humans can be comfortable. Then, when the current time reaches the set scheduled exit time ("YES" in step S19), the power transmission control unit 182 stops the power supply device 11, and the building air conditioning control unit 183 stops the building air conditioner 12 (step S20). If the battery 32 becomes fully charged before the scheduled exit time, the power transmission control unit 182 stops the power supply device 11 at that time.

[0051] In addition, when the current time reaches the set scheduled exit time, the vehicle entry / exit control unit 181 drives the exit door drive device 15 to open the exit door EX (step S21). When the exit door EX opens, the vehicle entry / exit control unit 181 wirelessly transmits an exit request to the vehicle controller 38 (step S22).

[0052] When the electric vehicle 300A receives the exit request (step S23), the vehicle controller 38 sends a movement command to the automatic parking mechanism 36 to the boarding area QA in front of the exit door EX outside the building X (step S24). Based on the received movement command, the automatic parking mechanism 36 automatically drives the electric vehicle 300A to exit the building X through the exit door EX and parks it in the boarding area QA.

[0053] At this time, if the relative position of the boarding area QA with respect to the power supply space SP is known, the electric vehicle 300A may be driven autonomously using dead reckoning technology that measures the position and orientation of the electric vehicle 300A from the wheel rotation speed and steering angle. Alternatively, if the latitude and longitude of the boarding area QA are known, the electric vehicle 300A may be driven autonomously by measuring its position by receiving GPS radio waves when it leaves the building X.

[0054] When the electric vehicle 300A moves to the boarding area QA ("YES" in step S25), the vehicle controller 38 transmits an exit completion notification to the power supply controller 18 (step S26). When the power supply controller 18 receives the exit completion notification (step S27), the vehicle entry / exit control unit 181 drives the exit door drive device 15 to close the exit door EX (step S28). Then, the user gets into the electric vehicle 300A in the boarding area QA, and starts driving the vehicle by operating the in-vehicle air conditioner 35 as appropriate according to the user's operation.

[0055] When another electric vehicle 300A stops in the drop-off area PA and the user performs an operation to supply power, the power supply controller 18 executes the operation described above again, thereby enabling the other electric vehicle 300A to receive power supply.

[0056] According to the first embodiment described above, when power is supplied to an electric vehicle, the air conditioning in the building in which the electric vehicle is parked is operated only for a certain period of time before the power supply is terminated, so that the temperature inside the vehicle can be adjusted while the power supply process is performed. As a result, after the power supply is terminated, the user can get into the electric vehicle with the temperature inside the vehicle at a comfortable temperature for humans. Since the on-board air conditioner is not operated when power is supplied, all of the supplied power is used to charge the battery, and the power supply process can be performed in a short time. Moreover, the above operations are performed automatically without any human intervention, so the availability of the electric vehicle can be increased. Furthermore, since the air conditioning in the building is operated only for a certain period of time, power consumption can be reduced.

[0057] In this embodiment, the electric vehicle enters the power supply space, the electric vehicle is powered, the building is air-conditioned, and the electric vehicle leaves the power supply space, all of which are performed unmanned. This prevents delays in the power supply process due to the actions of workers, increases the turnover rate of the power supply process for electric vehicles, and reduces the waiting time for users to charge.

[0058] In addition, because people do not get on or off the electric vehicle inside the building, there is no need to open or close the electric vehicle's doors inside the building, and no space is required for opening and closing the doors. Therefore, the width of the inside of the building only needs to be slightly larger than the width of the electric vehicle, and the volume inside the building can be made small, reducing the power required for air conditioning in the building.

[0059] In addition, since there are no people inside the building, there is no risk of people breathing and the CO2 concentration in the air inside the building will not increase. In addition, since electric vehicles run without emitting exhaust gases, the air inside the building will not be polluted by exhaust gases. Therefore, even if the opening doors are closed and the building is not ventilated, fresh air suitable for human breathing is maintained inside the building, so ventilation is not required when air-conditioning the building, and the electricity required for air-conditioning can be reduced.

[0060] In the above-described first embodiment, when there are multiple electric vehicles receiving power supply, each electric vehicle transmits an entry request together with its own vehicle-specific ID to the power supply controller 18. Then, the power supply controller 18 identifies each electric vehicle one by one using the ID and performs wireless communication, thereby making it possible to perform power supply processing for multiple electric vehicles.

[0061] Second Embodiment In the above-described first embodiment, the power supply facility 100A having one power supply space SP has been described. However, when such a power supply facility 100A is shared and used by a large number of electric vehicles for car sharing, for example, the timing of charging the electric vehicles may overlap, resulting in a waiting time for charging. When a waiting time for charging occurs, a user may not be able to use an electric vehicle when he or she wishes to.

[0062] In order to prevent such a situation from occurring, in this embodiment, a case will be described in which power is supplied to a plurality of electric vehicles 300B by a power supply facility 100B having a plurality of power supply spaces.

[0063] Configuration of power supply equipment according to the second embodiment The configuration of the power supply facility for an electric vehicle according to this embodiment will be described with reference to FIG. 6. The power supply facility 100B according to this embodiment includes devices 11-18 and the like installed in a plurality of buildings (buildings X1, X2, and X3), and a central control device 400. In this embodiment, each of the buildings X1, X2, and X3 has a configuration similar to that of the building X described in the first embodiment, and as shown in FIG. 6, the buildings X1, X2, and X3 may be constituted by sections partitioned by walls W1 and W2 within an integrated structure, or the buildings X1, X2, and X3 may be independent structures and installed separately from each other. When the buildings X1, X2, and X3 are configured as an integrated structure, the building air conditioner 12 in the central building X2 is installed on the ceiling of the building X2 because there is no wall facing the external space.

[0064] The buildings X1, X2, and X3 are provided with power supply spaces SP1, SP2, and SP3, entrance doors ET1, ET2, and ET3, and exit doors EX1, EX2, and EX3, respectively. In this embodiment, a case where there are three buildings will be described, but the number is not limited to three, and there may be two or four or more buildings.

[0065] In this embodiment, the outdoor wireless communication devices 16 in the buildings X1, X2, and X3 perform wireless communication with an electric vehicle 300B to be powered that is located outside the building X, and also perform wireless communication with the general control device 400. The power supply controllers 18 in the buildings X1, X2, and X3 and the general control device 400 may be connected by wires to perform wired communication.

[0066] The general control device 400 has a power supply space selection unit 41 and a wireless communication unit 42. When the power supply space selection unit 41 receives an entry request from the electric vehicle 300B, it selects an available power supply space as a power supply space for the electric vehicle 300B to enter. The wireless communication unit 42 wirelessly communicates with the outdoor wireless communication devices 16 of the buildings X1, X2, and X3, and the in-vehicle wireless communication device 33 of the electric vehicle 300B. The wireless communication unit 42 may also wirelessly communicate with the indoor wireless communication devices 17 of X1, X2, and X3.

[0067] In this embodiment, the configuration of the electric vehicle 300B supplied with power by the power supply facility 100B is similar to that of the electric vehicle 300A described in the first embodiment as shown in FIG. 3, and therefore detailed description of parts having the same functions will be omitted. The in-vehicle wireless communication device 33 of the electric vehicle 300B performs wireless communication with the outdoor wireless communication device 16 and the indoor wireless communication device 17 of the power supply facility 100B, and also performs wireless communication with the general control device 400. The vehicle controller 38 holds an ID for identifying the vehicle itself. The ID is different for each vehicle, and enables the vehicle to be identified and communicated with in wireless communication. For example, a telephone number can be used as the ID when wireless communication is performed using a mobile phone communication network.

[0068] <Operation when power supply equipment 100B according to the second embodiment supplies power to electric vehicle 300B> In this embodiment, the buildings X1, X2, and X3 of the power supply facility 100B are arranged in parallel with respect to the disembarking area PA and the boarding area QA as shown in FIG. 7. When the power supply facility 100B supplies power to the electric vehicle 300B, the electric vehicle 300B stops in the disembarking area PA in front of the entrances of the buildings X1 to X3, all passengers disembark, and the vehicle door is closed. Then, the user performs a power supply execution operation. When the power supply execution operation is performed, a series of operations described below is started, and the power supply facility 100B supplies power to the electric vehicle 300B. The user only performs the power supply execution operation, and the series of operations following the power supply execution operation are automatically performed without the need for user operation.

[0069] The operations executed by the power supply controller 18 of the power supply equipment 100B, the vehicle controller 38 of the electric vehicle 300B, and the power supply space selection unit 41 of the overall control device 400 when a power supply execution operation is performed will be described with reference to the flowcharts of FIGS. 8A and 8B.

[0070] When the user performs a power supply execution operation, the operation information is received by the vehicle controller 38 of the electric vehicle 300B. When the vehicle controller 38 receives the operation information of the power supply execution operation ("YES" in step S31), it determines whether or not there is a person inside the electric vehicle 300B based on the detection result by the human presence sensor 34 (step S32). When it determines that there is a person inside the vehicle ("YES" in step S32), it waits until there is no person inside the vehicle. When it determines that there is no person inside the vehicle ("NO" in step S32), the vehicle controller 38 stops the in-vehicle air conditioner 35 (step S33). Then, the vehicle controller 38 wirelessly transmits an entry request to enter any of the power supply spaces SP together with an ID that identifies the vehicle to the general control device 400 (step S34).

[0071] In the central control device 400, the power supply space selection unit 41 receives the entry request and the ID via the wireless communication unit 42 (step S35). Upon receiving the entry request, the power supply space selection unit 41 communicates with the power supply controllers 18 of the buildings X1, X2, and X3 to acquire information on the usage status (vacant or not) of each of the power supply spaces SP1, SP2, and SP3 (step S36). Then, based on the acquired information, if there is a vacant power supply space ("YES" in step S37), the power supply space selection unit 41 selects one of them as the power supply space to be entered by the electric vehicle 300B (step S38). Here, it is assumed that the power supply space selection unit 41 selects the power supply space SP1 as the power supply space to be entered by the electric vehicle 300B.

[0072] Next, the power supply space selection unit 41 transmits a power supply preparation command together with the ID received in step S35 (the electric vehicle 300B having this ID is the target for power supply in the building X1) to the power supply controller 18 of the building X1 corresponding to the selected power supply space SP1 (step S39). When the power supply controller 18 of the building X1 receives the power supply preparation command (step S40), the vehicle entry / exit control unit 181 drives the entrance door drive device 14 to open the entrance door ET1 and turns on the lighting device 13 (step S41). The vehicle entry / exit control unit 181 wirelessly transmits an entry permission notification to the vehicle controller 38 of the electric vehicle 300B having the ID received in step S39 (step S42).

[0073] When the vehicle controller 38 receives the entry permission notification (step S43), it requests position information of the white line from the marker recognition unit 37. When the position information of the white line is requested, the marker recognition unit 37 recognizes the position of the white line by capturing an image of the inside of the building X1 through the opening of the entrance door ET1 and analyzing the captured image information.

[0074] Here, the central control device 400 does not accept any entry requests from other electric vehicles until the process for the entry request received from the electric vehicle 300B is completed, that is, until the electric vehicle 300B enters and parks in any of the power supply spaces. Therefore, at this point, the power supply space whose entrance door is open and illuminated by the lighting device 13 is limited to the power supply space SP1. When the electric vehicle 300B enters the building X1 by autonomous driving, the entrance doors ET1 and ET2 of the other buildings X2 and X3 are closed, and only the white line L1 of the power supply space SP1 is visible, so that the marker recognition unit 37 can recognize the position of the white line L1 but does not recognize the white lines L2 and L3 in the other buildings X2 and X3. That is, in step S44, the vehicle controller 38 requests the marker recognition unit 37 for position information of the white lines without specifying L1, L2, and L3, but since only L1 is visible as a white line, the marker recognition unit 37 can recognize the position of the white line L1 by extracting the white lines from the image. The marker recognition unit 37 sends the obtained position information of the white line L1 to the vehicle controller 38.

[0075] When the vehicle controller 38 acquires the position information of the white line L1, the vehicle controller 38 determines the parking position of the electric vehicle 300B relative to the white line L1 based on the position of the power receiving device 31 in the vehicle body so as to align the power receiving device 31 with the position of the power supply device 11 in the power supply space SP1. In addition, in order to be able to align the positions without identifying the buildings X1, X2, and X3, the first predetermined distance described in the description of the first embodiment is the same for the buildings X1, X2, and X3, and the second predetermined distance is also the same for the buildings X1, X2, and X3. The third predetermined distance may be different for each electric vehicle 300B. For example, the third predetermined distance may be stored in the vehicle controller 38 of the electric vehicle.

[0076] When the vehicle controller 38 determines the parking position for the electric vehicle 300B, it sends a parking command to the automatic parking mechanism 36 to park the electric vehicle 300B at the determined position (step S44). Based on the received parking command, the automatic parking mechanism 36 automatically drives the electric vehicle 300B into the building X1 and parks the electric vehicle 300B at the determined parking position, aiming for the white line L1.

[0077] When the electric vehicle 300B is parked in the parking position ("YES" in step S45), the vehicle controller 38 transmits an entry end notification to the power supply controller 18 (step S46). When the power supply controller 18 receives the entry end notification (step S47), the vehicle entry / exit control unit 181 drives the entrance door drive device 14 to close the entrance door ET1 and turns off the lighting device 13 (step S48). The vehicle entry / exit control unit 181 also transmits a vehicle entry end notification to the central control device 400 (step S49). In the central control device 400, the power supply space selection unit 41 receives the vehicle entry end notification (step S50).

[0078] Thereafter, the power supply process and the exit process from the building X1 executed for the electric vehicle 300B in the power supply space SP1 are similar to the power supply process and the exit process from the building X1 executed for the electric vehicle 300A described in the first embodiment, and therefore detailed description thereof will be omitted (steps S51 and S52).

[0079] In the power supply process according to this embodiment, the scheduled exit time of the electric vehicle is reset for each power supply space and each time the electric vehicle newly enters. Also, the building air conditioning time (T) used to control the building air conditioner 12 may be different for each corresponding power supply space or may be the same for all of them.

[0080] Furthermore, since the power supply process according to this embodiment is executed independently for each power supply space, the stage at which the power supply process has progressed among the processes shown in FIGS. 8A and 8B varies for each building (each power supply space).

[0081] After the power supply space selection unit 41 finishes step S50, when another electric vehicle 300B stops in the drop-off area PA and the user performs an operation to execute power supply, the power supply space selection unit 41 executes the operation described above again, thereby allowing the other electric vehicle 300B to receive power supply. Unlike the first embodiment, since there are multiple power supply spaces, even while the first electric vehicle 300B is supplying power in a power supply space, the second electric vehicle 300B can be parked in another power supply space and receive power supply.

[0082] According to the second embodiment described above, in addition to having the same effects as the first embodiment, it is possible to simultaneously supply power to a plurality of electric vehicles, which allows the batteries of the electric vehicles to be charged quickly and increases the availability of the electric vehicles.

[0083] In the above-described second embodiment, the power supply equipment 100B in which the multiple power supply spaces SP1, SP2, and SP3 are arranged in parallel with respect to the disembarking area PA and the boarding area QA has been described. However, the present invention is not limited to this, and the multiple power supply spaces SP1, SP2, and SP3 may be arranged in series with respect to the disembarking area PA and the boarding area QA as in the power supply equipment 100C shown in FIG.

[0084] In this configuration, multiple power supply devices 11 are provided in each of multiple power supply spaces SP1, SP2, and SP3 that allow vehicles to be parked in a vertical line from the front to the rear. Then, the central control device 400 parks two or more electric vehicles 300 in a vertical line starting from the front power supply space SP1. After power supply to an electric vehicle 300 parked in the front power supply space SP1 is stopped, the central control device 400 moves the electric vehicle 300 out of the power supply space SP1 and moves the other electric vehicles 300 located behind the electric vehicle 300 to the front power supply space SP1.

[0085] In this power supply facility 100C, among the multiple electric vehicles 300 that are charging, the electric vehicle 300 that is parked and charging in the first power supply space SP1 will be moved to the boarding area QA and used first. Therefore, among the multiple power supply spaces SP1, SP2, and SP3, only the first power supply space SP1 needs to be installed in a space that can be air-conditioned.

[0086] Therefore, the leading power supply space SP1 is installed in the building X, and in the building X, a building air conditioner 12 is installed that is communicatively connected to the power supply device 11 installed in the power supply space SP1 and conditions the air inside the building X based on the operating state of the power supply device 11. The power supply spaces SP2 and SP3 do not have to be installed inside the building, and may be installed outdoors. Alternatively, the power supply spaces SP2 and SP3 may be installed in a building where a building air conditioner is not installed.

[0087] When power supply equipment 100C is configured in this manner, the operating rate of building air conditioner 12 installed corresponding to the leading power supply space SP1 is high. For example, when the leading power supply space SP1 is arranged in series with the other two power supply spaces SP2 and SP3 as shown in Fig. 9, the building air conditioner 12 operates three times more frequently than when the three power supply spaces SP1, SP2, and SP3 are arranged in parallel. Therefore, the building air conditioner 12 may be operated at all times.

[0088] In the first and second embodiments described above, operations that can be performed when the windows and ventilation openings of the electric vehicle 300 (electric vehicle 300A or electric vehicle 300B) can be automatically opened and closed by commands from the vehicle controller 38 will be described with reference to the flowchart in FIG.

[0089] When air conditioning for the building X is started ("YES" in step S61), the building air conditioning control unit 183 of the power supply controller 18 sends an air conditioning start notification for the building X to the vehicle controller 38 (step S62). When the vehicle controller 38 receives the air conditioning start notification for the building X (step S63), it automatically opens at least one of the windows (power windows) and the ventilation openings (step S64). When air conditioning for the building X is stopped ("YES" in step S65), the building air conditioning control unit 183 sends an air conditioning stop notification for the building X to the vehicle controller 38 (step S66). When the vehicle controller 38 receives the air conditioning stop notification for the building X (step S67), it automatically closes the windows and the ventilation openings (step S68).

[0090] In this way, by automatically opening at least one of the windows and the ventilation openings of the electric vehicle 300 while the building air conditioner is operating, ventilation inside and outside the electric vehicle 300 is improved while the building air conditioner 12 is operating, and the time it takes for the temperature inside the electric vehicle 300 to reach a temperature at which humans can be comfortable is shortened. This shortens the building air conditioning time (T) and the operation time of the building air conditioner 12, and reduces power consumption. In addition, when the building air conditioner 12 stops and the electric vehicle 300 exits the power supply space SP, the windows and ventilation openings of the electric vehicle 300 are automatically closed, so that the air inside the electric vehicle 300 is less susceptible to the effect of the temperature of the outside air, and the temperature inside the vehicle is maintained at a comfortable level. Note that, if only one of the windows or the ventilation openings can be opened and closed automatically, only that one may be opened and closed automatically according to the flow described in FIG. 10.

[0091] Also, the fan of the vehicle-mounted air conditioner may be operated in an outside air introduction mode while the air conditioning of the building X is in operation. The power supplied by operating the fan of the vehicle-mounted air conditioner is also used to operate the fan, but since the power consumption of the fan operation is significantly less than that of heating and cooling, it does not have a significant effect on the battery charging time.

[0092] Furthermore, when at least one of the windows and the ventilation openings of the electric vehicle 300 is configured to be automatically opened and closed as described above, an ozone generator (not shown) may be installed in the building X, and ozone fumigation of the inside of the electric vehicle 300 may be performed during charging. For example, before operating the building air conditioner, ozone gas is generated from the ozone generator and at least one of the windows and the ventilation openings of the electric vehicle 300 is opened, thereby circulating the ozone gas inside the electric vehicle 300. Here, the timing for generating the ozone gas and the concentration of the ozone gas are set so that the ozone is decomposed by the scheduled departure time of the electric vehicle 300. By performing the process in this manner, it is possible to perform sterilization processing of the inside of the electric vehicle 300 using ozone gas while charging the electric vehicle 300.

[0093] In the above-described first and second embodiments, a white line L is provided as a marker in the power supply space, and the position of the white line L is recognized from image information captured by an image capture device mounted on the electric vehicle 300, thereby determining the parking position of the electric vehicle 300. However, the present invention is not limited to this method, and a retroreflector may be installed as a marker in the power supply space, and the electric vehicle 300 may be equipped with a LIDER as the marker recognition unit 37. In this case, the LIDER measures the distance and direction to the installed retroreflector and recognizes the position of the power supply space, thereby determining the parking position of the electric vehicle 300. In this method, the LIDER can emit a laser light for distance measurement by itself to measure the distance to the retroreflector, and therefore illumination by the lighting device 13 is not required.

[0094] As another method for determining the parking position of the electric vehicle 300, UWB (Ultra Wide Band) technology can be used. In this method, a tag that transmits UWB pulses is installed as a marker in the power supply space, and a UWB sensor is mounted on the electric vehicle 300 as the marker recognition unit 37. The UWB sensor receives the pulses transmitted from the tag and recognizes the position of the power supply space, thereby determining the parking position of the electric vehicle 300. Since the UWB sensor measures the position of the tag by receiving pulses (radio waves), this method also does not require illumination by the lighting device 13. Furthermore, since the entrance door ET is in an open state during measurement, the entrance door ET does not interfere with the radio waves, and the UWB pulses transmitted by the tag in the power supply space are received by the UWB sensor through the opening of the entrance door ET, making it possible to recognize the position of the power supply space.

[0095] In the above-described first and second embodiments, the power receiving device 31 is installed on the underside of the electric vehicle 300, and the power supply device 11 is installed on the floor of the building X, but the present invention is not limited to this. It is sufficient that the power receiving device 31 and the power supply device 11 are installed so that when the electric vehicle 300 is properly parked in the power supply space SP, the power receiving device 31 and the power supply device 11 face each other closely and are in a state where contactless power supply is possible. For example, the power receiving device 31 may be installed on the side of the electric vehicle 300, and the power supply device 11 may be installed on the wall of the building X.

[0096] In the above-described first and second embodiments, the case where the disembarking area and the boarding area are on opposite sides of the power supply space SP has been described. However, the present invention is not limited to this, and the boarding area and the disembarking area may be on the same side of the power supply space SP, and one building opening may serve as both the entrance and exit for the electric vehicle 300.

[0097] In the above-described first and second embodiments, the case where there is one each of the drop-off area and the boarding area in the power supply equipment 100A, 100B has been described, but the present invention is not limited to this, and there may be a plurality of drop-off areas and boarding areas. For example, in a power supply equipment installed in a large apartment building or the like having a plurality of entrances, a drop-off area and a boarding area may be provided for each entrance, and residents may use the power supply equipment by getting on and off at the drop-off area and the boarding area at the entrance closest to their rooms.

[0098] In the description of the first embodiment, the disembarking area PA and the boarding area QA are shown by solid lines in Fig. 4, but this is a conceptual representation of the areas, and the solid lines may or may not be drawn on the road surface. For example, the areas may be visibly indicated by painting with a color different from the road surface, or a certain location may simply be specified as the disembarking area PA or the boarding area QA, although it cannot be distinguished from the outside. The same applies to the disembarking area PA and the boarding area QA in the second embodiment.

[0099] In addition, the positional relationship between the drop-off area PA and the boarding area QA and the building X in the first embodiment is not limited to the positional relationship illustrated in FIG. 4. It is sufficient that the in-vehicle wireless communication device 33 can wirelessly communicate with the outdoor wireless communication device 16 or the indoor wireless communication device 17 of the power supply facility 100A, the automatic parking mechanism 36 can drive the electric vehicle 300A from the drop-off area PA to the building X and automatically park it, and the automatic parking mechanism 36 can drive the electric vehicle 300A from the building X to the boarding area QA and automatically park it. For example, the distance between the drop-off area PA and the building X may be closer or farther than the distance illustrated in FIG. 4. The drop-off area PA and the building X are illustrated in the same direction in FIG. 4, but may be oriented in different directions. The distance between the boarding area QA and the building X may be closer or farther than the distance illustrated in FIG. 4. The boarding area QA and the building X are illustrated in the same direction in FIG. 4, but may be oriented in different directions. The positional relationship between the drop-off area PA and the boarding area QA and the buildings X1, X2, and X3 in the second embodiment is also similar. The orientations of the buildings X1, X2, and X3 may be different, and the buildings do not have to be located in a straight line.

[0100] In the first and second embodiments described above, the walls and ceiling of the building X may be made of a material that includes or is made of a material that blocks electromagnetic fields (e.g., a magnetic material, a non-magnetic conductive material, or a composite material thereof) that blocks electromagnetic fields. By making the walls and ceiling of the building X out of such a material, it is possible to prevent the electromagnetic field generated by the non-contact power supply from propagating from inside the building X to the outside.

[0101] In the above-mentioned first and second embodiments, the building air conditioner is operated for a certain period of time before the power supply to the electric vehicle is terminated, but the present invention is not limited to this. For example, when the power supply equipment is used frequently or when the building air conditioner must be operated for a long time until the temperature inside the building reaches the set temperature in a cold region, the average power consumption of the building air conditioner may be reduced by operating the building air conditioner at all times rather than repeatedly starting and stopping the building air conditioner each time the power supply process is performed. In such a case, the power consumption may be reduced by operating the building air conditioner at all times.

[0102] Furthermore, the electric vehicle that is charged in the above-described first and second embodiments may be a hybrid vehicle or a fuel cell vehicle that is equipped with an engine and a fuel cell in addition to a battery.

[0103] Although several embodiments have been described, the embodiments can be modified or modified based on the above disclosure. All components of the above embodiments and all features described in the claims may be individually extracted and combined as long as they are not mutually inconsistent.

[0104] This disclosure can contribute, for example, to Sustainable Development Goal (SDG) Goal 11, "Make cities and human settlements inclusive, safe, resilient and sustainable." [Explanation of symbols]
