Description

The present invention relates to a mechanical parking lot.

A mechanical parking lot is known as a parking lot that can efficiently park a large number of vehicles in a small space. As one of them, a pallet-type mechanical parking lot is provided in which a vehicle is loaded on a pallet and the pallet is moved back and forth or left and right using rails and grooves to carry the pallet to an empty parking space. In addition, by combining this pallet-type mechanical parking lot with a lift and a three-dimensional parking layer, a mechanical parking lot with higher parking efficiency is also provided.

On the other hand, low-noise and clean electric vehicles and plug-in hybrid vehicles (hereinafter collectively referred to as EV vehicles) are beginning to spread. EV vehicles are powered by power from secondary batteries such as lithium-ion batteries mounted on them. In order to charge this secondary battery, it currently takes about half a day to charge. Therefore, a technique has been proposed in which an EV vehicle is accommodated in a predetermined charging parking space prepared in a mechanical parking lot and the secondary battery of the EV vehicle is charged by using the parking time (for example, a patent). Reference 1).

Japanese Unexamined Patent Publication No. 2012-241344

In a conventional mechanical parking lot, it takes several hours to half a day to complete charging of one EV vehicle. If the EV vehicle being charged allows the pallet loaded to move due to the loading and unloading of other pallets, it takes a longer time to complete the charging. Therefore, in general, the movement of the pallet during charging is prohibited. Therefore, in a conventional mechanical parking lot, the charging parking space in which the charging pallet is housed cannot be used for loading and unloading other pallets. Therefore, the number of charging parking spaces provided is limited to a range that does not interfere with entry and exit. In addition, the time required for warehousing and delivery is relatively long.

The present invention has been made in view of such circumstances, and one of the exemplary objects of the embodiment is to provide a mechanical parking system capable of solving at least one of the above-mentioned problems.

A mechanical parking lot according to an aspect of the present invention includes a plurality of pallets for loading a vehicle, a plurality of parking spaces each accommodating a pallet, and a plurality of parking spaces, including a charging pallet corresponding to charging the vehicle.

The hoistway 96 is provided along the vertical direction (z direction) and communicates with each of the B1F parking room 14, the B2F parking room 16, and the B3F parking room 18. At the lower end of the hoistway 96, a lifting device 94 for raising and lowering the lift frame 88 is installed. Two masts 90 are provided at the four corners of the hoistway 96.

The lift frame 88 is supported by two masts 90 so as to be able to move up and down, and is moved up and down along the hoistway 96 by the lifting device 94. A first transfer device 56 is provided on the upper part of the lift frame 88. The lift frame 88, the two masts 90, and the elevating device 94 include the lift frame, the two masts, and the elevating device described in Japanese Patent Application Laid-Open No. 2009-197417, which the applicant filed earlier. Can be applied.

The pallet 100 is a flat plate-shaped member, and the vehicle loading surface 100a, which is the upper surface on which the vehicle is mounted, has a substantially rectangular shape. The pallet 100 has a uniform size, and one pallet has a size that allows one vehicle to be loaded.

In the present embodiment, the plurality of pallets 100 are all charging pallets corresponding to the charging of the EV vehicle 22, and include an outlet 102 and a power receiving unit 104. When the EV vehicle 22 is charged while parked, the power supply port of the EV vehicle 22 and the outlet 102 are electrically connected by a power supply cable 110.

In the present embodiment, the power receiving unit 104 is provided on one of the two long sides of the pallet 100, and when the pallet 100 is accommodated in the charging parking space 52, it is electrically connected to the power supply unit 44 of the power supply system 40. To. The power receiving unit 104 may be provided on the two long sides of the charging pallet 100, or may be provided on at least one of the two short sides. The power receiving unit 104 is electrically connected to the outlet 102, receives the electric power supplied from the power supply system 40, and supplies the electric power to the EV vehicle 22 via the outlet 102 and the power supply cable 110.

The first transfer device 56 is provided on the upper part of the lift frame 88 and moves the pallet 100 in the x direction. The first transport device 56 moves the pallet 100 between the hoistway 96 and each parking room. The second transfer device 58 is provided in each of the parking spaces 50 and moves the pallet 100 in the x direction or the y direction. The second transport device 58 moves the pallet 100 between the parking spaces. The transfer device described in Japanese Patent Publication No. 7-29681, which the applicant has previously applied for, can be applied to the second transfer device 58.

The B1F parking room 14 has 15 parking spaces 50 arranged in 5 columns in the x direction and 3 rows in the y direction intersecting the x direction. Between the adjacent parking spaces 50, a fall prevention roller 38 is installed to support the pallet 100 when it moves across the parking space 50. The B2F parking room 16 and the B3F parking room 18 have the same configuration as the B1F parking room 14.

The parking space 50 is configured to accommodate one pallet 100. The parking space 50 is one parking area in the parking room where the vehicle is parked by accommodating the pallet 100 on which the vehicle is loaded.

The charging parking space 52 is a parking space 50 capable of supplying power to the EV vehicle 22 that requires power supply. The charging parking space 52 is provided with a power supply system 40 that supplies electric power to the pallet 100 housed in the charging parking space 52. In the present embodiment, the charging parking spaces 52 are arranged at three locations farthest from the hoistway 96 among the plurality of parking spaces 50 included in each parking room.

As will be described in detail later, in the present embodiment, the pallet 100 being charged is also a movable pallet, and a puzzle operation for entering and leaving another vehicle is determined. That is, the pallet 100 being charged is not prohibited from moving. Therefore, even if the charging parking space 52 is provided at an arbitrary position, it does not become a restriction for obtaining a solution for the puzzle operation. Therefore, the position of the charging parking space 52 is not particularly limited and can be provided at any position. In this case, more charging parking spaces 52 can be provided as compared with the conventional mechanical parking lot.

The power supply system 40 is configured to be able to supply electric power for quickly charging the vehicle loaded on the pallet 100 to the pallet 100. Here, "quick charging" refers to charging that supplies DC or AC power of 40 kW or more. The power supply system 40 includes a power supply device 42 and a power supply unit 44. The power feeding device 42 converts, for example, the power of three-phase AC 300V into direct current and supplies it to the power feeding unit 44. The power supply terminal of the power supply unit 44 is configured to be mechanically contactable with the charging terminal of the charging parking space 52 as described later. When the power supply terminal of the power supply unit 44 and the charging terminal of the charging parking space 52 come into contact with each other, electric power is supplied to the EV vehicle 22 via the outlet 102 and the power supply cable 110.

The operation panel 28 has a function as a user interface for a vehicle driver or a staff member of the mechanical parking lot 10 (hereinafter, these are collectively referred to as a “user”). The operation panel 28 is connected to the control device 30, and transmits a control signal to the control device 30 in response to the input operation.

At the time of warehousing, the user operates the operation panel 28 to instruct warehousing. The operation panel 28 generates a warehousing instruction signal and transmits it to the control device 30. When charging during warehousing, the user instructs warehousing and charging during warehousing. In this case, the operation panel 28 generates a warehousing instruction signal including a request for charging during warehousing and transmits it to the control device 30. At the time of warehousing, the user operates the operation panel 28 to input a vehicle management number which is an identification number for identifying the vehicle to be warehousing. The operation panel 28 generates a delivery instruction signal including a vehicle management number and transmits it to the control device 30.

FIG. 3 is a block diagram showing the functions and configurations of the control device 30. Each block shown here can be realized by an element such as a computer CPU (Central Processing Unit) or a mechanical device in terms of hardware, and can be realized by a computer program or the like in terms of software. It depicts a functional block realized by their cooperation. Therefore, it will be understood by those skilled in the art who have referred to this specification that these functional blocks can be realized in various forms by combining hardware and software.

The control device 30 includes a reception unit 112, a management unit 116, and a holding unit 120. The holding unit 120 includes a parking status holding unit 122.

FIG. 4 is a diagram showing an example of parking status information held by the parking status holding unit 122. The parking status holding unit 122 holds the pallet number, the parking space ID, the vehicle management number, the warehousing time, and the charging state in association with each other as the parking status information. The pallet number is an identification number for identifying each pallet. The parking space ID is an identification number for identifying each parking space. The vehicle ID is an identification number that identifies the vehicle. The warehousing time is the time when the vehicle is warehousing. The charging state is a status indicating whether or not the vehicle has been charged, and "waiting for charging", "charging", "charged", and "no charging required" are set.

Returning to FIG. 3, the reception unit 112 receives the control signal transmitted from the operation panel 28. When the reception unit 112 receives the warehousing instruction signal or the warehousing instruction signal from the operation panel 28, the reception unit 112 notifies the management unit 116 of the contents thereof.

The management unit 116 controls the first transfer device 56, the second transfer device 58, and the elevating device 94, and moves the pallet 100 to the boarding / alighting room 12 or a specific parking space 50. In the present embodiment, the management unit 116 determines the movement of the pallet 100 in the mechanical parking lot 10 required for the movement of the pallet 100 by using a known puzzle operation algorithm. The management unit 116 transmits a command to the first transfer device 56, the second transfer device 58, and the elevating device 94 so that the determined movement of the pallet 100 is realized.

When the management unit 116 receives the warehousing instruction signal, the management unit 116 moves the pallet on which the vehicle is loaded to the predetermined parking space 50. At this time, the management unit 116 determines the puzzle operation for warehousing, assuming that the pallet 100 being charged is also a movable pallet 100. Since the vehicle can be charged quickly, if you have a reasonable number of charging parking spaces 52, you can allow the pallets to move while charging for the entry and exit of other pallets, but all you want to charge. This is because it is expected that the EV vehicle can be fully charged. The management unit 116 transmits a command to the first transfer device 56, the second transfer device 58, and the elevating device 94 so that the determined movement of the pallet is realized. When moving the pallet 100 being charged, the management unit 116 moves the pallet 100 after charging, that is, stopping the power supply from the power feeding device 42 to the pallet 100. When the warehousing is completed, the management unit 116 returns the pallet 100 from which charging has been stopped to the charging parking space and restarts charging.

When the management unit 116 receives the warehousing instruction signal, the management unit 116 refers to the parking status holding unit 122 and moves the pallet loaded with the vehicle corresponding to the vehicle management number included in the warehousing instruction signal to the boarding / alighting room 12. At this time, the management unit 116 determines the puzzle operation for warehousing, assuming that the pallet 100 being charged is also a movable pallet 100, as in the case of warehousing. The management unit 116 transmits a command to the first transfer device 56, the second transfer device 58, and the elevating device 94 so that the determined movement of the pallet is realized. The operation when moving the pallet 100 during charging is the same as that at the time of warehousing. In addition, the management unit 116 deletes the corresponding parking status information from the parking status holding unit 124 when the delivery is completed.

When the vehicle to which the delivery instruction is given is being charged, the management unit 116 interrupts the charging of the vehicle and moves the pallet to the boarding / alighting room 12.

When the charging parking space 52 becomes vacant, the management unit 116 refers to the parking status holding unit 124 and puts the pallet 100 loaded with the vehicle to be charged into the vacant charging parking space 52. Move. When there is a vacancy in the plurality of charging parking spaces 52, they are accommodated in the charging parking space 52 close to the parking space 50 in which the pallet 100 is accommodated. The management unit 116 electrically connects the power supply unit 44 of the power supply system 40 and the power reception unit 104 of the pallet 100 to start charging, and sets the charging state of the pallet 100 held by the parking status holding unit 124 to ". Change to "Charging".

The management unit 116 periodically checks whether there is a pallet to start charging when the charging parking space is still vacant, and if there is a pallet that meets the conditions, starts charging the pallet. Let me. The time interval to be checked regularly is, for example, 1 minute. In addition to the regular confirmation timing, the pallet to be charged is confirmed at the timing when the parking lot 10 is entered and exited from the mechanical parking lot 10.

The management unit 116 confirms whether there is a pallet waiting for charging whose charging state is not "charged" held in the parking status holding unit 124, and if there is a pallet that satisfies the condition, the vehicle that should start charging the pallet is loaded. The pallet is made. At this time, if there are a plurality of pallets that satisfy the conditions, the pallet with the oldest warehousing time is given priority.

When the charging of the vehicle accommodated in the charging parking space 52 is completed, the management unit 116 moves the pallet 100 out of the charging parking space and accommodates the pallet 100 in the predetermined parking space. In addition, the charging state of the parking status information corresponding to the fully charged pallet 100 is changed to "charged".

Whether or not the charging of the vehicle is completed is determined based on the current value of the electric power supplied by the power supply system 40, the actual time of charging, and the like.

The above is the basic configuration of the mechanical parking lot 10. Subsequently, the operation of the mechanical parking lot 10 will be described.

FIG. 5 is a flowchart showing a process when a vehicle is stored in the mechanical parking lot 10. When a vehicle warehousing instruction is accepted (S10), if the warehousing instruction includes a charging instruction (Y in S12), and if there is a vacancy in the charging parking space (Y in S14), the vehicle for which the warehousing instruction has been given (hereinafter, warehousing) The pallet 100 loaded with (referred to as a vehicle) is moved to the empty charging parking space (S16). If there is no vacancy in the charging parking space (N in S14), the parking status of the warehousing vehicle is updated to "waiting for charging" (S18), and the pallet 100 loaded with the warehousing vehicle is moved to the vacant parking space (S20). When the warehousing instruction does not include the charging instruction (N in S12), the pallet 100 loaded with the warehousing vehicle is moved to the empty ordinary parking space (S20). In the processing of S16 and S20, the puzzle operation for moving the warehousing vehicle to the parking space is determined as the pallet 100 in which the EV vehicle charging in the charging parking space can also be moved, and the pallet is moved according to the determined puzzle operation. .. At this time, when moving the pallet during charging, the pallet is moved after the charging is stopped, and when the movement of the warehousing vehicle is completed, the pallet for which the charging is stopped is returned to the charging parking space and the charging is restarted.

FIG. 6 is a flowchart showing a process when the vehicle is discharged from the mechanical parking lot 10. When the delivery instruction of the vehicle is received (S30), if the vehicle for which the delivery instruction is given (hereinafter referred to as the delivery vehicle) is being charged (Y in S32), the charging is interrupted (S34), and then the delivery vehicle is released. The loaded pallet 100 is moved to the boarding / alighting room 12 (S36). If the leaving vehicle is not charging (N in S32), the pallet 100 loaded with the leaving vehicle is moved to the boarding / alighting room 12 (S36). In the process of S36, the puzzle operation for moving the leaving vehicle to the parking space is determined as the pallet 100 in which the EV vehicle charging in the charging parking space can also be moved, and the pallet is moved according to the determined puzzle operation. At this time, when moving the pallet during charging, the pallet is moved after the charging is stopped, and when the movement of the leaving vehicle is completed, the pallet for which the charging is stopped is returned to the charging parking space and the charging is restarted.

Subsequently, the configurations of the power feeding unit and the power receiving unit 104 will be described in more detail.

7 (a) and 7 (b) are side views of the power feeding unit 44 and the power receiving unit 104. FIG. 7A shows a state in which the power supply terminal 60 of the power supply unit 44 and the power reception terminal 106 of the power reception unit 104 are not in contact with each other, and FIG. 7B shows the power reception of the power supply terminal 60 of the power supply unit 44 and the power reception unit 104. Indicates a state in which the terminal 106 is in contact with the terminal 106.

The power receiving unit 104 includes a power receiving terminal 106 and a power receiving frame 108. The power receiving frame 108 is formed of an insulator and is fixed to a pallet 100 (not shown in FIGS. 7A and 7B). In the present embodiment, the power receiving terminal 106 is formed in a tubular shape and is held by the power receiving frame 108. The power receiving terminal 106 is formed of a conductor, for example, metal. One end side of the power receiving terminal 106 faces the power feeding unit 44, and the wiring inside the pallet 100 is connected to the other end side.

The power supply unit 44 includes a power supply terminal 60, a support unit 62, and a locking mechanism 64. The power supply terminal 60 includes a power supply electrode 68 and a continuity confirmation electrode 70. The power feeding electrode 68 and the continuity confirmation electrode 70 are formed of a conductor, for example, metal. The power supply electrode 68 and the continuity confirmation electrode 70 are insulated by an insulator 32. The insulator 32 is formed of, for example, a resin.

The power feeding electrode 68 includes a contact portion 72 and an extending portion 74. The shape of the contact portion 72 is not particularly limited, but is formed so as to be able to enter the insertion hole 106a of the power receiving terminal 106 while contacting the peripheral surface 106b of the insertion hole 106a of the power receiving terminal 106. The contact portion 72 is formed with a taper on the tip end side so as to easily enter the insertion hole 106a. The extending portion 74 extends in the x direction from the end of the contact portion 72 on the anti-power receiving unit side (left side in FIGS. 7A and 7B).

In the present embodiment, the continuity confirmation electrode 70 is formed in a tubular shape and surrounds the extending portion 74 of the power feeding electrode 68. The entire continuity confirmation electrode 70 is located closer to the anti-power receiving unit than the contact portion 72 in the x direction.

The power supply terminal 60 can be reciprocated in the x direction by a drive mechanism (not shown), specifically between the retracted position (position in FIG. 7A) and the contact position (position in FIG. 7B). Is configured to be reciprocating.

The "evacuation position" is a position where the pallet 100 moving in the charging parking space 52 does not come into contact with the puzzle operation. When the power feeding terminal 60 is located in the retracted position, the movement of the pallet 100 is not hindered by the power feeding terminal 60. Further, it is possible to prevent the pallet 100 from coming into contact with the power feeding terminal 60 and damaging the power feeding terminal 60.

The "contact position" is a position on the anti-feeding unit side (right side in FIGS. 7A and 7B) in the x direction from the retracted position, and the feeding electrode 68 and the continuity confirmation electrode 70 of the feeding terminal 60 are located. , It is a position where it enters the insertion hole 106a of the power receiving terminal 106 of the pallet 100 stopped at the stop position and comes into contact with the peripheral surface of the insertion hole 106a. The "stop position" is a position where the pallet that has moved between the parking spaces 50 according to a normal puzzle operation stops.

As described above, the entire continuity confirmation electrode 70 is located closer to the anti-power receiving unit than the contact portion 72 in the x direction. Further, the outer peripheral surface 72a of the contact portion 72 and the outer peripheral surface 70a of the continuity confirmation electrode 70 are flush with each other. Therefore, in a state where the power feeding terminal 60 is located at the contact position (position shown in FIG. 7B) and the continuity confirmation electrode 70 enters the insertion hole 106a of the power receiving terminal 106 and is in contact with the peripheral surface 106b thereof. The contact portion 72 also always enters the insertion hole 106a of the power receiving terminal 106 and is in contact with the peripheral surface 106b thereof. On the contrary, when the contact portion 72 does not enter the insertion hole 106a of the power receiving terminal 106 and therefore the contact portion 72 is not in contact with the power receiving terminal 106, the continuity confirmation electrode 70 also enters the insertion hole 106a. Therefore, the continuity confirmation electrode 70 is not in contact with the power receiving terminal 106.

The support unit 62 includes a terminal holding portion 34 and two bases 36. The terminal holding portion 34 has a tubular shape in the present embodiment, and holds the power feeding terminal 60 slidably in the x direction inside the terminal holding portion 34. The two bases 36 are vertically spaced apart, for example, fixed to the frame of a parking room. The two bases 36 support the terminal holding portion 34 and thus the feeding terminal 60 via the spring 78, that is, support the terminal holding portion 34 so as to be displaceable in the vertical direction. In this case, even if the power receiving terminal 106 moves up and down due to vibration of the pallet 100, the power feeding terminal 60 can also move up and down accordingly, and poor contact between the power receiving terminal 106 and the power feeding terminal 60 can be prevented.

The locking mechanism 64 includes a rod 80, a rod support portion 82, and a claw 84. The rod 80 is a long rod-shaped member. The rod support portion is fixed to the outer circumference of the terminal holding portion 34. The rod support portion rotatably supports one end side of the rod around an axis parallel to the y direction. A claw 84 is fixed to the outer periphery of the other end side of the rod. A protrusion 107 is provided on the outer peripheral surface of the power receiving terminal 106. The rod 80 is driven by a drive mechanism (not shown), the longitudinal direction is inclined with respect to the x direction, and the claw 84 is not locked to the protrusion 107 of the power receiving terminal 106 (position in FIG. 7A). , The longitudinal direction coincides with the x direction, and the claw 84 rotates between the locking position (position of FIG. 7B) in which the claw 84 is locked to the protrusion 107 of the power receiving terminal 106. At the locking position, the claw 84 is located closer to the anti-feeding unit side than the protrusion 107 provided on the outer peripheral surface of the power receiving terminal 106, and faces the protrusion 107 in the x direction, so that the power feeding terminal 60 is the power receiving terminal 106. It is prevented from coming out of. The locking mechanism 64 may be provided on the power receiving unit 104. In this case, the claw 84 may be locked to a protrusion provided on the outer peripheral surface of the terminal holding portion 34.

FIG. 8 shows a circuit diagram formed by the power supply unit 44, the pallet 100, and the EV vehicle 22 in the state of FIG. 7B. The power supply unit 44 further includes a charging power supply 130, a continuity confirmation power supply 132, a relay coil 134, a first switch 136, and a second switch 138. The charging power supply 130 is a high-power power supply for quick charging of the vehicle, and the continuity confirmation power supply 132 is a low-power power supply for continuity confirmation. The first switch 136 and the second switch 138 are controlled by the management unit 116 of the control device 30.

The first route 140 is a route for supplying power to the EV vehicle 22. The first path 140 includes a charging power supply 130, a power feeding electrode 68, a power receiving terminal 106, a first switch 136, and a second switch 138.

The second path 142 is a path for confirming that the power feeding electrode 68 and the power receiving terminal 106 are in contact with each other. The second path 142 includes a continuity confirmation power supply 132, a continuity confirmation electrode 70, a power supply electrode 68, a power receiving terminal 106, and a relay coil 134. A part of the second route 142 corresponds to the route indicated by the dotted arrow in FIG. 7 (b).

The continuity confirmation unit 144 on the second path 142 includes a continuity confirmation electrode 70 and a power receiving terminal 106. The state in which the continuity confirmation electrode 70 and the power receiving terminal 106 are in contact and electrically connected corresponds to the state in which the continuity confirmation unit 144 is on, and the continuity confirmation electrode 70 and the power receiving terminal 106 are in contact with each other. The state of not being electrically connected corresponds to the state in which the continuity confirmation unit 144 is off.

When the continuity confirmation unit 144 is turned on, the current from the continuity confirmation power supply 132 flows on the second path 142. Then, the first switch 136 is turned on by the electromagnetic force generated by the current flowing through the relay coil 134.

When the management unit 116 detects that the first switch 136 is turned on and the power feeding terminal 60 and the power receiving terminal 106 are locked by the locking mechanism 64, the management unit 116 turns the second switch 138 on and the EV vehicle. The power supply to 22 is started. The management unit 116 may have the second switch 138 turned on in advance. In this case, when the first switch 136 is turned on, a current flows through the first path 140, and electric power is supplied to the EV vehicle 22. Further, the management unit 116 may turn on the second switch 138 when the first switch 136 is turned on.

In any case, when the first switch 136 is in the ON state, the continuity confirmation electrode 70 and the power receiving terminal 106 are in contact with each other, and in that case, the power feeding electrode 68 and the power receiving terminal 106 are always in contact with each other. Therefore, that is, since the power for quick charging is supplied only when the power feeding electrode 68 and the power receiving terminal 106 are in contact with each other, it is possible to prevent sparks from occurring between the power feeding electrode 68 and the power receiving terminal 106. ..

Whether or not the first switch 136 is in the ON state can be determined, for example, by the value of the current flowing through the first path 140. Further, whether or not the power feeding terminal 60 and the power receiving terminal 106 are locked can be determined by detecting, for example, whether or not the rod 80 is located at the locked position by a sensor (not shown).

When the continuity confirmation unit 144 is turned off, the current from the continuity confirmation power supply 132 does not flow on the second path 142. Then, the electromagnetic force is not generated, and the first switch 136 is turned off. In this case, of course, power is not supplied to the power feeding electrode 68. The first path 140 and the first switch 136 can be regarded as forming a shielding mechanism that shields the power supply when the power feeding electrode 68 and the power receiving terminal 106 are not in contact with each other.

Subsequently, the operations of the power supply system 40 and the power receiving unit 104 will be described. 9 (a) to 9 (d) are views showing the state of the power supply system 40 and the power receiving unit 104 during charging.

In FIG. 9A, the power supply terminal 60 is located at the retracted position. Subsequently, the control device 30 stops the pallet 100 at the stop position of the charging parking space 52 as shown in FIG. 9B. In this state, the power feeding electrode 68 and the insertion hole of the power receiving terminal 106 face each other in the x direction. Subsequently, the control device 30 moves the power supply terminal 60 to the contact position as shown in FIG. 9C. As a result, the power feeding electrode 68 and the continuity confirmation electrode 70 enter the insertion hole 106a of the power receiving terminal 106 and come into contact with the peripheral surface 106b thereof. Then, a current flows through the first path 140, and the first switch 136 is turned on. Subsequently, as shown in FIG. 9D, the control device 30 turns on the second switch when the power feeding terminal 60 is locked with respect to the power receiving terminal 106. Then, a current flows through the second path 142, and electric power is supplied to the EV vehicle 22. When charging is completed, the control device 30 turns off the second switch 138, releases the lock between the power feeding terminal 60 and the power receiving terminal 106, and moves the power feeding terminal 60 to the evacuation position. The second switch 138 may be turned off after the power supply terminal 60 and the power receiving terminal 106 are unlocked.

As described above, according to the present embodiment, electric power for rapidly charging the vehicle is supplied to the pallet 100. As a result, the EV vehicle can be fully charged in a shorter time than before, for example, about 15 to 30 minutes. In this case, the EV vehicle for which the parking time is short can be fully charged.

Further, according to the present embodiment, since the vehicle can be charged quickly, if a certain number of charging parking spaces 52 are provided, the pallets being charged can be moved for loading and unloading other pallets. Even so, it is expected that all EV vehicles that wish to be charged during warehousing can be fully charged. Therefore, the pallet 100 being charged can also be used as a movable pallet to determine the puzzle operation for entering and exiting another vehicle. In this case, the number of movements in the puzzle operation can be reduced and the time required for loading and unloading can be shortened as compared with the case where the pallet 100 being charged is prohibited from moving. Further, when the pallet 100 being charged is also a movable pallet, even if the charging parking space 52 is provided at an arbitrary position, there is no restriction for obtaining a solution of the puzzle operation. Therefore, the position of the charging parking space 52 is not particularly limited and can be provided at any position. In this case, more charging parking spaces 52 can be provided as compared with the conventional mechanical parking lot.

The conventional mechanical parking lot is provided with a normal pallet that does not support charging of the vehicle and a corresponding charging pallet, and the normal pallet waits in the boarding / alighting room for the next warehousing. Therefore, when warehousing an EV vehicle to be charged during warehousing, it is necessary to move the charging pallet to the boarding / alighting room, and the driver of the EV vehicle is kept waiting during that time. On the other hand, according to the present embodiment, all of the plurality of pallets 100 are charging pallets corresponding to charging the vehicle. Therefore, a charging pallet stands by in the boarding / alighting room 12. Therefore, there is no waiting time for moving the charging pallet to the boarding / alighting room 12.
