In addition, a charging plug 20 connected to the power supply port 11 a of the vehicle 11 is connected to the charging device 15 via a power supply cable 21. The charging device 15 is connected to an operation unit 22 for instructing whether or not the parking lot user is charged. The vehicle 11 is provided with a communication unit 11b that serves as an information receiving unit and an information transmitting unit.

  On the other hand, the mechanical parking lot 10 is provided with a charge controller 23 as shown in FIG. The charge controller 23 includes a control unit 24 that controls charging of the storage battery 14 and movement of the pallet P, a communication unit 25 that serves as an information reception unit and an information transmission unit, a power supply unit 26 that supplies power, Is provided. The power supply unit 26 receives power transmitted from the power system 27, converts the received power into a form suitable for charging, and supplies the power via the power transmission connector 28. An electric power system is a power transmission system for transmitting electric power and is owned by an electric power company. The power available from the power system 27 is determined by a supply and demand contract between the owner of the mechanical parking lot 10 and the power company.

  In addition, a determination device 29 that determines whether or not the vehicle 11 to be stored is an electric vehicle 11 such as an EV or a PHV equipped with the in-vehicle battery D is provided at the entrance / exit 13 of the mechanical parking lot 10. Is provided. The determination result of the determination device 29 is transmitted to the parking control device 12.

  In the mechanical parking lot 10, a charging position for charging the storage batteries 14 of the pallets CP1 to CP4 is defined on the movement locus of the pallet P. That is, the storage batteries 14 of the pallets CP1 to CP4 are charged by moving the pallets CP1 to CP4 to the charging position. In the present embodiment, the charging position is set at one place on the movement trajectory of the pallet P.

Hereinafter, the processing content which the control part 24 of the charge controller 23 performs is demonstrated according to FIGS.
The charge controller 23 stores management information shown in FIG. The management information indicates, for each pallet P, the battery capacity of the storage battery 14, the current charge amount, the empty status indicating whether or not the vehicle 11 is parked, and the pallet P being charged in the storage battery 14. The charging display is associated. In FIG. 3, “◯” in the vacant state indicates that the vehicle is vacant, “×” indicates that the vehicle is parked, and “◯” in the charging display indicates that the battery is being charged.

And the control part 24 of the charge controller 23 performs the storage battery charge process shown in FIG. 4 for charging the storage battery 14 of pallets CP1-CP4 based on the management information mentioned above.
The control unit 24 acquires the state of the pallets CP1 to CP4 where the storage battery 14 is provided (step S10). The states of the palettes CP1 to CP4 are transmitted from the communication unit 18 of each charging device 15 and received by the communication unit 25 of the charge controller 23. In step S10, the control unit 24 acquires the charge amount of each storage battery 14 as the state of the pallets CP1 to CP4. The acquired charge amount is stored as management information.

  Next, based on the management information, the control unit 24 determines whether or not all of the empty pallets CP1 to CP4 have been charged (step S11). In step S11, the control unit 24 determines whether or not the storage battery 14 is in a fully charged state. And when the determination result of step S11 is affirmative, the control part 24 returns to step S10, and repeats a process. On the other hand, when the determination result of step S11 is negative, the control unit 24 determines that a pallet that has not been charged is a pallet to be charged. Then, the control unit 24 determines one charging pallet to be charged from pallets that have not been charged (step S12). At this time, the control unit 24 sets a pallet with a small charge amount as a charging pallet.

  Next, the control unit 24 moves the charging pallet to the charging position (step S13). At this time, the control unit 24 transmits information indicating the charging pallet to be moved to the charging position to the parking control device 12. And the control apparatus 12 for parking moves each pallet P so that a charging pallet may be moved to a charging position based on the received information. As a result, the charging pallet moves to the charging position and stops when it reaches the charging position.

  Next, the control unit 24 connects the power transmission connector 28 of the charge controller 23 to the power receiving connector 16 of the charging pallet (step S14). And the control part 24 starts charge of a charge pallet (step S15). Thereby, the storage battery 14 of the charging pallet is charged with the power supplied from the power supply unit 26. Moreover, the control part 24 which started charge acquires charge amount of the storage battery 14 from the charging device 15 of a charge pallet, it memorize | stores it in management information, and controls charge (step S16). And the control part 24 determines whether charge was completed based on management information (step S17). When this determination result is negative, that is, when the storage battery 14 is not fully charged, the control unit 24 returns to step S16 and repeats the process.

  On the other hand, if the determination result in step S17 is affirmative, that is, if the storage battery 14 is fully charged, the control unit 24 stops charging the charging pallet and connects the power receiving connector 16 of the charging pallet and the power transmission connector 28 of the charging controller 23. Is released. And the control part 24 returns to step S10, and repeats a process. That is, if there is another pallet to be charged (No at Step S11), the control unit 24 moves the pallet as a charging pallet to the charging position and starts charging.

  Moreover, the control part 24 of the charge controller 23 performs the loading / unloading process shown in FIG. 5 for loading / unloading the vehicle 11 based on the management information mentioned above. The control unit 24 executes the loading / unloading process when receiving a loading request or a loading request from the parking control device 12.

  The control unit 24 determines whether or not there is a charging pallet when receiving a loading / unloading request (step S20). When this determination result is affirmative, the control unit 24 stores the charging pallet in the management information (step S21). For example, as shown in FIG. 3, when a warehousing request is received during charging of the pallet CP4, information indicating that the pallet CP4 is a charging pallet (“◯” in the charging display in the figure) is stored. . Next, the control part 24 stops charge of a charge pallet (step S22). Moreover, the control part 24 cancels | releases the connection of the power receiving connector 16 of a charge pallet, and the power transmission connector 28 of the charge controller 23 (step S23). And the control part 24 transfers to step S24. Further, when the control unit 24 makes a negative determination in step S20, that is, when there is no charging pallet, the control unit 24 proceeds to step S24.

  The control unit 24 that has shifted to step S24 determines a loading / unloading pallet to be loaded or unloaded. The control part 24 determines the pallet in which the vehicle 11 as a delivery object is mounted based on the management information shown in FIG. Moreover, the control part 24 determines an incoming / outgoing pallet from an empty pallet based on the management information shown in FIG. 3, when the incoming request is received. When the warehousing request is made, a determination result as to whether or not the warehousing vehicle 11 is an electric vehicle is also transmitted. This determination is performed by the determination device 29 provided at the entrance / exit 13. When the vehicle to be stored is a non-electric vehicle, the control unit 24 preferentially determines the pallets NP1 and NP2 that are not provided with the storage battery 14 as the storage / pallet. On the other hand, when the vehicle to be stored is an electric vehicle, the control unit 24 preferentially determines the charged pallet as the loading / unloading pallet using the pallets CP1 to CP4 provided with the storage battery 14. Note that preferential determination means that if there is no empty pallet that meets the conditions, another pallet may be determined.

  And the control part 24 which determined the loading / unloading pallet moves the loading / unloading pallet to the loading / unloading port 13 used as a loading / unloading position (step S25). At this time, the control part 24 transmits the information which designates the loading / unloading pallet moved to the loading / unloading position to the parking control device 12. And the control apparatus 12 for parking moves each pallet P so that an incoming / outgoing pallet may be moved to an incoming / outgoing position based on the received information. Thereby, the loading / unloading pallet moves to the loading / unloading position and stops when it reaches the loading / unloading position.

  Next, the control unit 24 determines whether the loading / unloading of the vehicle 11 with respect to the loading / unloading pallet is completed (step S26). If this determination is negative, the control unit 24 returns to step S26 and repeats the process. On the other hand, when the determination result of step S26 is positive, the control unit 24 moves the charging pallet to the charging position and restarts charging (step S27). That is, the control unit 24 transmits an instruction to move the charging pallet stored in the management information to the charging position to the parking control device 12. And the control apparatus 12 for parking moves each pallet P so that a charging pallet may be moved to a charging position based on the received information. As a result, the charging pallet moves to the charging position again and stops when it reaches the charging position. Thereafter, the control unit 24 connects the power receiving connector 16 of the charging pallet and the power transmitting connector 28 of the charge controller 23 to resume charging.

Next, the processing content which the control part 17 of the charging device 15 performs is demonstrated according to FIG.6 and FIG.7.
The controller 17 of the charging device 15 executes a vehicle charging process shown in FIG. 6 for charging the vehicle 11.

  The control unit 17 performs confirmation for starting charging (step S30). In step S <b> 30, the control unit 17 confirms connection between the charging plug 20 and the vehicle 11. Further, the control unit 17 determines whether or not there is an instruction to start charging (step S31). The instruction to start charging is transmitted from the vehicle 11 side. And when the determination result of step S31 is negative, the control part 17 returns to step S30, and repeats a process. On the other hand, when the determination result of step S31 is affirmative, the control unit 17 starts charging the in-vehicle battery D of the vehicle 11 (step S32). Next, the control part 17 which started charge acquires charge amount of the vehicle-mounted battery D via the communication part 11b of the vehicle 11, and controls charge (step S33). Then, the control unit 17 determines whether or not to complete charging (step S34). If this determination result is negative, the control unit 17 returns to step S33 and repeats the process. On the other hand, when the determination result of step S <b> 34 is affirmative, the control unit 17 stops charging the in-vehicle battery D. In addition, the control part 17 affirmatively determines step S34, when the vehicle-mounted battery D will be in a full charge state, or when completion | finish of charge is instruct | indicated by a user's operation.

  Moreover, the control part 17 of the charging device 15 will perform the communication process shown in FIG. 7, if the communication request | requirement from the charge controller 23 is received. The charge controller 23 makes a communication request in step S10 of the storage battery charging process shown in FIG.

  The control part 17 acquires the charge amount of the storage battery 14 as a state of a self pallet (step S40). And the control part 17 transmits the information acquired by step S40 to the charge controller 23 via the communication part 18 (step S41). Thereby, the charge controller 23 acquires the charge amount of the storage battery 14 managed by the charging device 15 of the transmission source, and stores it in the management information.

Next, the operation of this embodiment will be described.
The storage batteries 14 provided on the pallets CP1 to CP4 are charged when the control unit 24 of the charge controller 23 executes a storage battery charging process (FIG. 4). This storage battery charging process is performed when the vehicle 11 is not loaded or unloaded. The storage battery 14 is charged by moving a charging pallet to be charged to a charging position determined in the parking lot. For this reason, in the mechanical parking lot 10 of this embodiment, it is not necessary to route a power supply line etc. with respect to the pallets CP1 to CP4, and the charging pallet to be charged is charged by using a time zone during which the warehousing is not performed. The battery 14 can be charged by being moved to a position.

  Moreover, when loading / unloading is performed during charging of the charging pallet, the control unit 24 of the charging controller 23 executes the loading / unloading process (FIG. 4), whereby charging of the charging pallet is temporarily stopped. Then, after completion of loading / unloading, charging of the charging pallet is resumed. Further, when the electric vehicle 11 is stored, a pallet for which the storage battery 14 has been charged is selected from the pallets CP1 to CP4, and the vehicle 11 is mounted. For this reason, the vehicle 11 is charged by the storage battery 14 in a fully charged state.

Therefore, according to the present embodiment, the following effects can be obtained.
(1) The storage battery 14 is provided on the pallets CP1 to CP4, and electric power is supplied from the storage battery 14 to the vehicle 11 to charge the in-vehicle battery D. And the storage battery 14 moves pallets CP1-CP4 to the charging position defined in the parking lot, and charges it in the charging position. For this reason, it is not necessary to route a power supply line for supplying power from outside the pallet to charge the vehicle 11 in the parking lot. Therefore, charging can be performed with a simple equipment configuration.

  (2) The pallets CP1 to CP4 determined to be charged are moved to the charging position, and the storage battery 14 is charged. For this reason, the storage battery 14 can be charged using the time slot | zone which is not entering / exiting. Therefore, the storage battery 14 can be charged by using the fact that the pallets CP1 to CP4 are movable in the mechanical parking lot 10 and moving the pallets CP1 to CP4. As a result, the equipment configuration can be simplified.

  (3) If a storage / reception request is made during the charging of the storage battery 14, the storage battery 14 is temporarily stopped to be charged, and the charging is resumed after the storage / recharging. For this reason, while being able to perform loading / unloading without delay, the storage battery 14 can also be charged reliably.

  (4) When the electric vehicle 11 is stored, a pallet in which the storage battery 14 is fully charged is selected, and the vehicle 11 is stored in the pallet. For this reason, the stored vehicle 11 can be charged by supplying power from the storage battery 14 that has been charged.

  (5) Charging the vehicle 11 is performed using the storage batteries 14 provided on the pallets CP1 to CP4, so that the vehicle 11 to be charged is charged even when the vehicle 11 is charged simultaneously with a plurality of pallets. Thus, control such as power distribution and distribution is not required, and the control configuration can be simplified. That is, each vehicle 11 can be charged by the control for each of the pallets CP1 to CP4.

  (6) The storage battery 14 is provided on the pallets CP <b> 1 to CP <b> 4, and the vehicle-mounted battery D is charged with the power of the storage battery 14. For this reason, it is possible to suppress the contract amount of power available from the power system 27. Therefore, an increase in running cost of the mechanical parking lot 10 can be suppressed. As a result, user convenience (such as low charge setting) can be achieved.

  (7) By providing the pallets CP1 to CP4 provided with the storage battery 14 and the pallets NP1 and NP2 not provided with the storage battery 14, both the electric vehicle 11 and the non-electric vehicle 11 can be supported. A mechanical parking lot 10. And by supplying electric power from the storage battery 14 to the vehicle 11 and charging it, and setting the charging position in the parking lot and charging the storage battery 14, the required number of pallets at the initial installation of the mechanical parking lot 10 CP1 to CP4 may be installed. Then, as the use of the electric vehicle 11 is expanded, a pallet provided with the storage battery 14 may be added. Therefore, the initial installation cost of the mechanical parking lot 10 can be suppressed, and the mechanical parking lot 10 rich in expandability can be provided.

  (8) Moreover, the structure of the mechanical parking lot 10 is made different by changing the charging position of the vehicle 11 (on the pallets CP1 to CP4 provided with the storage battery 14) and the charging position of the storage battery 14 (position determined in the parking lot). For example, it is possible to provide a charging system that can flexibly cope with the scale (number of pallets) and the movement type of the pallets.

  (9) Since the in-vehicle battery D of the vehicle 11 is charged by the storage battery 14 provided on the pallets CP1 to CP4, it is possible to provide a charging system that can meet the user's expectation to charge while parking. That is, unlike the case of power sharing charging in which power supplied from the power system 27 is distributed and supplied and charged, the vehicle 11 has the power of the storage battery 14 provided on the pallets CP1 to CP4 stopped on the pallets CP1 to CP4. Can be occupied. That is, the vehicle 11 can be charged for the electric power stored in the storage battery 14.

In addition, you may change the said embodiment as follows.
○ When the electric vehicle 11 is received, the charge amount of the vehicle-mounted battery D of the vehicle 11 is acquired, and the pallets CP1 to CP4 having the storage batteries 14 that can supply power according to the charge amount are determined as the input / output pallets. May be. For example, the control unit 24 calculates the required charging amount of the vehicle 11 from the charging amount of the in-vehicle battery D, moves the pallet where the charging amount of the storage battery 14 exceeds the charging required amount to the warehousing position, and moves the vehicle 11. Recharge and charge. Specifically, in the management information shown in FIG. 3, the pallet for receiving the vehicle 11 having a required charge amount of 5 kWh is not the pallet CP2 having a charge amount of 30 kWh (fully charged state) but a charge amount of 10 kWh (fully charged). The pallet CP4 of the following charge amount may be determined. In this way, a pallet suitable for the situation of the vehicle 11 to be stored can be determined. And even if the storage battery 14 is not in a fully charged state, the vehicle 11 can be stored in the pallet, and the vehicle 11 can be charged with a required charge amount. In other words, in a parking lot where it is impossible to imagine what kind of situation the vehicle 11 will be in, appropriate warehousing management can be realized by assigning a pallet according to the vehicle situation at the time of warehousing. For example, it is possible to minimize the occurrence of a situation where a pallet that can charge the required charge amount cannot be assigned. The required amount of charge can be calculated from the amount of charge when the battery capacity of the in-vehicle battery D is known. In addition, information on the vehicle type may be acquired, and the required charge amount may be calculated by grasping the battery capacity of the in-vehicle battery D from the vehicle type. Moreover, when the required charge amount can be directly acquired from the vehicle 11 side, the information may be used.

  In addition, as in the management information shown in FIG. 8, the battery capacities of the storage batteries 14 of the pallets CP1 to CP4 may be varied. Then, when the electric vehicle 11 is received, the vehicle type of the vehicle 11 may be acquired, and the loading / unloading pallet may be determined based on the battery capacity of the in-vehicle battery D mounted on the vehicle type. For example, the control unit 24 moves the pallet provided with the storage battery 14 having a battery capacity capable of bringing the in-vehicle battery D to a fully charged state from the battery capacity of the in-vehicle battery D to the loading / unloading position, and loads the vehicle 11. Charge with it. Specifically, in the management information shown in FIG. 8, the pallets CP1 and CP2 provided with the storage battery 14 having a battery capacity of 50 kWh or 30 kWh are determined as pallets for receiving the vehicle 11 having the battery capacity of the in-vehicle battery D of 20 kWh. May be. In this way, a pallet suitable for the situation of the vehicle 11 to be stored can be determined. Therefore, appropriate warehousing management can be realized in the mechanical parking lot 10.

  ○ In addition, warehousing management may be performed by combining the above two other examples. For example, as an example of the warehousing management, the control unit 24 enters the vehicle 11 in which the battery capacity of the in-vehicle battery D is 50 kWh but the charge amount is 40 kWh (that is, the required charge amount is 10 kWh). Pallets CP3 and CP4 provided with storage batteries 14 having a battery capacity of 15 kWh may be determined as the outgoing pallets.

  In addition, as in the management information shown in FIG. 9, the pallet owners PA to PD may be determined for each of the pallets CP1 to CP4. In this case, each pallet CP1 to CP4 is provided with a storage battery 14 having a battery capacity according to the request of the owners PA to PD. And the control part 24 acquires owner information from the vehicle 11 at the time of warehousing, and moves the pallet suitable for the owner information to a warehousing position. The owner information may be acquired from the vehicle 11 or may be a method of inputting identification information to a device installed at the entrance / exit 13 or a method of causing the device to read an IC card. Such a configuration can be a configuration suitable for a mechanical parking lot when used in an environment where a user can be identified, such as a contract parking lot or an apartment house.

  The method for acquiring vehicle type information from the vehicle 11 may be information acquisition through communication with the vehicle 11. Further, image acquisition means such as a camera may be installed in the site of the mechanical parking lot 10 such as the entrance / exit 13, and the vehicle type may be recognized from the acquired image of the vehicle 11.

(Circle) the structure of embodiment is applicable to various mechanical parking lots, such as a vertical circulation type, an elevator type, and a horizontal circulation type.
A plurality of charging positions may be set for the mechanical parking lot 10. Since the plurality of storage batteries 14 can be charged in parallel, a pallet that can be stored can be prepared earlier.

The storage battery 14 may be embedded in the floor with respect to the pallet P, or may be installed exposed on the floor at a position not related to the parking space.
O The number of pallets P with storage batteries 14 installed in the mechanical parking lot 10 may be arbitrarily changed. For example, one pallet P with the storage battery 14 may be installed in the mechanical parking lot 10, or all the pallets P may be the pallet P with the storage battery 14.

  When the charge amount of the storage battery 14 is insufficient during the charging of the vehicle 11, the vehicle 11 may be charged by moving the pallet to the charging position. In this case, when the charge amount of the storage battery 14 falls below a predetermined amount, the control unit 17 of the charging device 15 transmits the information to the control unit 24 of the charge controller 23. And the control part 24 which received the information transmits the instruction | indication which moves a pallet to a charge position to the control apparatus 12 for parking. If the pallet that is charging the storage battery 14 is in the charging position, the control unit 24 interrupts the charging of the storage battery 14 of the pallet so that the pallet with insufficient charge is preferentially charged. More preferred.

  O Adjacent or adjacent pallets CP1 to CP4 may be connected to each other with a power supply line so that the power of the storage battery 14 can be transferred to both sides. If comprised in this way, when the charge amount of the storage battery 14 runs short during charge of the vehicle 11, for example, electric power can be received from the storage battery 14 of the other pallet connected with the feeder.

  (Circle) you may change the conditions which affirmatively determine step S17 of the storage battery charging process shown in FIG. For example, when the charge capacity of the storage battery 14 exceeds a predetermined capacity (for example, 80%), an affirmative determination may be made in step S17. In this case, step S11 also determines whether or not charging of a predetermined capacity has been completed.

  In step S12 of the storage battery charging process shown in FIG. 4, when there are a plurality of pallets to be charged, the charging order may be the order in which the charging amount is large or the order in which it is small. Further, the charging order may be determined in advance, and charging may be performed according to the order.

  A storage battery different from the storage battery 14 of the pallet P may be provided in the mechanical parking lot 10. Then, when the power received from the power system 27 is stored in the storage battery and the storage battery 14 of the pallet P is charged, the power supply unit 26 may supply the power stored in the storage battery to the storage battery 14 of the pallet P. If it does in this way, the storage battery 14 of the pallet P can be charged at high speed.

The transmission / reception of information between the charging device 15 and the charging controller 23 may be wired communication or wireless communication.
The parking control device 12 and the charge controller 23 may be constructed as a single control device. Further, the determination result of the determination device 29 may be transmitted to the charge controller 23.

  A solar power generation facility may be installed on the outer wall surface of the mechanical parking lot 10, and the storage battery 14 of the pallet P may be charged using the generated power. Moreover, wind power generation equipment may be installed in the mechanical parking lot 10 and the storage battery 14 of the pallet P may be charged using the generated power. In this case, the power supply source to the storage battery 14 may be only a solar power generation facility or a wind power generation facility, or power may be supplied from the power system 27. According to such a configuration, a mechanical parking lot 10 that effectively uses natural energy can be constructed. In addition, if wind power generation equipment is installed in the three-dimensional mechanical parking lot 10, the cost of creating a tower for installing a wind turbine for power generation can be reduced.

  ○ The charging device 15 and the vehicle 11 of the pallets CP1 to CP4 are systems in which charging is performed by mechanically connecting the charging plug 20 to the vehicle 11, but the vehicle and the charging unit are electrically connected without using the charging plug 20. It may be a non-contact system that is connected to the battery for charging. As shown in FIG. 10, in the non-contact type system, the power receiving side coil 30 attached to the vehicle 11 side and the power transmitting side coil 32 of the pallet side equipment 31 embedded in the floor of the pallet P are matched. The vehicle 11 is stopped. At this time, the power receiving side coil 30 and the power transmitting side coil 32 are separated and brought into a non-contact state. In the non-contact system, the vehicle-mounted battery D of the vehicle 11 is charged by receiving the power from the power transmission side coil 32 by the power reception side coil 30. In such a non-contact system, the vehicle controller 33 mounted on the vehicle 11 and the power controller 34 installed in the pallet facility 31 can communicate wirelessly. Moreover, the storage battery 14 is mounted on the pallet P similarly to the embodiment, and power is supplied from the storage battery 14. Non-contact systems include a resonance method and an electromagnetic induction method.
