Description

  The present invention relates to a multilevel parking facility having a function of charging a battery of an electric vehicle mounted on a pallet.

  2. Description of the Related Art Conventionally, three-dimensional parking apparatuses such as an elevator parking apparatus, a plane reciprocating parking apparatus, and a multistage parking apparatus are widely used as a mechanical parking apparatus for parking a vehicle using an internal combustion engine as a power source.

  On the other hand, in recent years, the use of electric vehicles using an electric motor as a power source instead of an internal combustion engine is increasing. This electric vehicle is superior in environmental conservation because it does not emit exhaust gas, but it is necessary to charge electricity to a battery instead of conventional fuel. However, since this charging usually takes a long time, a multi-story parking device has been invented to charge using the time stored in the parking device as described above.

  For example, the present applicant, as a parking device having a charging function, has a female connector provided on the pallet side and a male connector on the parking shelf side at the back of each parking shelf (on the side of the hoistway) of the elevator type three-dimensional parking device. Invented is a type in which a circuit connector is provided that allows the connector to be engaged and disengaged by a solenoid, and charging is performed by connecting the circuit connector with a solenoid during parking (for example, see Patent Document 1). .

  Moreover, as another prior art, in an elevator type multilevel parking apparatus, a charger is provided on the multilevel parking apparatus side, and the pallet and the parking rack side are connected by a contact point provided facing the pallet moving direction. Yes (see, for example, Patent Document 2).

Furthermore, as another technology, the configuration of a power supply mechanism, a charge amount measuring mechanism, and a settlement mechanism in a rotary multi-story parking device, an elevator slide multi-story parking device, a lift / slide multi-story parking device, a simple multi-story parking device, etc. Some have tried to provide (see, for example, Patent Document 3).
Japanese Patent No. 2789062 Japanese Patent No. 2908940 Japanese Patent No. 2787728

  However, in Patent Documents 1 to 3, the same number of charging pallets and charging parking parts are provided, and the electric vehicle mounted on the charging pallet is charged by the stored parking part. As the number increases, wiring and connection means associated therewith are also required, and reliability decreases due to an increase in space and cost and an increase in failure rate due to an increase in parts.

  In particular, in the case of the above-mentioned Patent Document 2, since energization is automatically started / terminated by loading / unloading of the pallet to / from the parking portion, discharge occurs due to contact interruption while energization occurs, and the contact is damaged. There is a risk of wear.

  Furthermore, especially in the case of the above-mentioned Patent Document 3, since the charger is mounted on the pallet, the charger becomes quite large depending on the type of battery to be applied, so the space for parking the pallet is scraped, There is a risk that the entire apparatus becomes large. Moreover, although the start of energization from the charger is performed by the connection detection sensor, it is not economical to provide such a dedicated sensor. In addition, although an overcharge sensor is provided, it is not economical and there is a risk of overcharging depending on the timing of detecting the presence or absence of overcharging.

  In addition, since these do not move the pallet from the storage position at the time of entry to the time of exit, the vehicle stored in the parking shelf far from the entrance / exit has a long moving distance by the transfer device and a long waiting time at the time of exit.

  Therefore, the present invention provides a multi-level parking system that can smoothly charge an electric vehicle mounted on a pallet by improving cost efficiency and space saving by minimizing cost and space charging facilities. The purpose is to provide equipment.

  In order to achieve the above object, the present invention includes a plurality of parking units for storing a pallet on which a vehicle is mounted, and a transport unit that transports the pallet between a vehicle loading / unloading unit and the parking unit. The parking unit is a three-dimensional parking facility, and the parking unit includes at least one charging parking unit including a parking unit side connection unit linked to a charger for charging the battery of an electric vehicle using a battery as a driving source. The pallet is stored in the charging parking part, and is provided with a pallet side connecting part for connecting a charging side connecting part connected to the charging connection port of the electric vehicle with the parking part side connecting part. The charging pallet is provided with a number that is at least one more than the number of charging parking units, and the total number of all pallets including the charging pallet includes the charging parking unit. To the total number of parking portion of Musubete, wherein 1 to that number fraction less of the charging parking unit. “Electric vehicles” in this specification and claims include automobiles and motorbikes as stipulated by the Road Traffic Law, and 2 to 8 wheels, other wheel numbers and crawlers, and include tracks and overhead lines. A vehicle that is not required and that can be driven by the power of an electric motor (including a combination of an engine and human power, for example, including a plug-in hybrid and electric assist). In addition, the “charging side connection portion” in the specification and claims refers to a connection portion with an electric vehicle such as a charging cable and a charging cable outlet. As a result, one or more charging pallets more than the number of charging parking units can be sequentially moved to the charging parking unit, and the electric vehicles mounted on the charging pallet can be sequentially charged. In addition, it is possible to construct a multi-level parking facility that minimizes the space-consuming charging facilities (charger, wiring, etc.) and improves economy and space saving. In addition, by using the empty space in the parking part for temporary storage of the pallet, etc., it is possible to carry out smooth charging work and perform efficient charging with reduced waiting time.

  In addition, the controller has a control device that controls energization from the charger, and the control device includes, as one of the conditions for starting energization from the charger, the charging side connection unit and the parking unit side connection unit, After the connection, the completion of a predetermined stage of the pallet transport procedure by the transport means may be a condition. If it does in this way, when connecting a charge side connection part and a parking part side connection part, it will be possible to prevent arc discharge at the time of a connection so that a voltage may not be applied to a connection part.

  And a control device that controls energization from the charger. The control device determines that a predetermined time has elapsed after the start of energization and that the electric power being charged is a condition for ending energization from the charger. It may be any one or any combination of a call to leave for the vehicle and a charging current or voltage reaching a predetermined value. If it does in this way, the stable charge of a battery and prevention of an overcharge can be aimed at by any one or combination of the passage of time, the calling out, the value of current or voltage.

  Further, the control device has at least one function of identifying that the electric vehicle mounted on the charging pallet needs to be charged and a charging pallet stored in a parking unit other than the charging parking unit. If there is a sheet, the electric pallet that needs to be charged is mounted after the charging pallet is transferred from the charging parking unit based on the charging conditions of the electric vehicle mounted on the charging pallet of the charging parking unit. The charging pallet may be transferred to the charging parking portion and charged to the electric vehicle. As the above-mentioned “function for identifying that charging is necessary”, for example, the charging connection port of the electric vehicle detects that the charging button has been pressed by operating the operation panel at the time of warehousing. It is electrically detected that it is connected to the vehicle, and it is detected that charging is not performed after warehousing. The “predetermined condition” includes the end of energization from the charger, the staying time of the parking part for charging reaching a predetermined time, and the like. In this way, the charging pallet equipped with the fully charged electric vehicle is transferred to the parking part where the pallet is not stored, or when a warehousing call is made, it is transferred to the vehicle entry / exit part to leave the vehicle. After that, the pallet for charging is transferred to a parking part in which other pallets are not stored, and the charging pallet equipped with an electric vehicle that requires charging is transferred to the charging parking part for charging. The electric vehicle can be efficiently charged.

  Furthermore, the parking part side connection part may be a contact wire of a predetermined length, and the pallet side connection part may be a current collector that contacts the contact wire and energizes. In this way, by storing the charging pallet, the current collector is in contact with the contact wire and power is supplied, so that stable power supply can be performed.

  The multi-level parking facility may be an elevator multi-level parking facility. In this way, it is possible to configure an elevator type multilevel parking facility that efficiently charges an electric vehicle mounted with a pallet replaced efficiently.

  Furthermore, the condition for starting energization from the charger may be the completion of the pallet lateral feed operation by the transport means. In this way, charging can be started in conjunction with the completion of the lateral feeding operation of the conveying means for laterally feeding the charging pallet, and charging is started quickly while preventing arc discharge at the start of charging. be able to.

  Moreover, you may make it judge the function which identifies that charge of the said control apparatus is required by operation by the operator at the time of warehousing. As the operation by the user, as described above, there are a button operation on the operation panel, connection of the charging side connection portion, and the like. If it does in this way, it can identify and memorize | store that charging is required by operation of the user at the time of warehousing, and it can be charged automatically using the time during parking.

  Furthermore, the control device may have a function of outputting pallet identification information in conjunction with a charging completion / incomplete identification determination by the charger. This “pallet identification information” includes a pallet number, a contractor ID, a vehicle ID, and the like. The “output” includes, for example, display on the operation panel and data transfer. If it does in this way, a user can know a charge state etc. before using a car, and it can become a reference for selecting subsequent charge or driving.

  According to the present invention, it is possible to provide a multilevel parking facility that can charge many electric vehicles by combining the economical efficiency and the space saving by increasing the operation rate while minimizing the charging facility. Become.

I have. Although FIG. 2 shows an electric vehicle 7A (L) with a standard height as an electric vehicle, the electric vehicle 7A (H) with a high vehicle height has the same configuration.

  Further, in this embodiment, as shown in FIG. 2 (b), the charging side connection portion 8 is also provided in front of the electric vehicle 7A (L) (right side in the figure), and the direction built in the multi-story parking facility 1 Charging can be performed in the same manner even when the pallet 52A is turned 180 ° by a conversion device (turntable or the like; not shown). Moreover, these charging side connection parts 8 are provided at diagonal positions so as not to interfere with charging of an electric vehicle provided with the battery side connection part 72 at the front of the vehicle body. In the figure, the charging side connection portion 8 on the right side is in an unused state, and the connector 83 is locked to the stand 81. Further, in this embodiment, since the direction changing device is built in as described above, the current collecting device 84 is also provided at the diagonal position (the right side in FIG. 2 (b) is not shown), and on one side. Two current collectors 84 are provided. Also, two contact wires 62 are laid in parallel corresponding to the current collector 84.

Moreover, when it is necessary to store the electric vehicle from which the request | requirements, such as the voltage with respect to the charger 61, differ, even if any of the contact electric wires, the current collector, and the charger is provided for each parking part 5, Good.

  Moreover, although the charging side connection part 8 (connection means) of this embodiment showed the example in which the cable 82 provided with the connector 83 in the pallet 52A for charging was provided in the stand 81, it is not limited to these. As shown in FIG. 3, instead of the connector 83 and the cable 82, a stand 85 provided with a receptacle (an outlet having a hole shape different from that of a normal power outlet) is provided, or as shown in FIG. An opening 86 may be provided in the central raised portion, and the cable 87 with a connector may be accommodated in the opening 86. The charging side connecting portion 8 (connecting means) has a configuration other than the above embodiment. May be.

  Next, a connection path from the connector 83 of the charging side connecting portion 8 to the charger 61 will be described with reference to FIGS. 1 and 2A, 2B. The connector 83 of the charging side connection portion is provided so as to be freely engaged and disengaged from a stand 81 standing on the pallet 52, and the cable 82 of the charging connection portion extends along the stand 81 (either internal or external). It may be guided to the lower part of the pallet 52 and connected to the current collector 84.

  On the other hand, the lower end of the contact electric wire 62 laid on the charging parking portion 5 </ b> A for storing and charging the pallet 52 </ b> A having the charging side connection portion 8 is connected to the charger 61 via the wiring 63.

It is fixed in place on the object.

  When the charging pallet 52A is fed into the charging parking portion 5A, the current collector 84 approaches toward the contact wire 62, and the current collector 84 is appropriately position-corrected by the action of a guide or the like. Then, the contact wire 62 is contacted. The current collector 84 is maintained in a state of being reliably in contact with the contact wire 62 by an urging means such as a spring (not shown). By this contact, charging power is supplied to the charging side connecting portion 8 through the path of the charger 61 → the wiring 63 → the contact electric wire 62 → the current collector 84 → the cable 82.

  In this embodiment, the charging pallet 52A supplies the electric power to the electric vehicles 7A (L) and 7A (H) that require charging from the charger 61 on the charging pallet 52A. And when the discharging operation from the elevator 41 is completed and the pallet traversing means returns onto the elevator 41 (not the pallet by the conveying means). Control is performed so that power supply from the charger 61 is started at the completion of a predetermined stage of the transport procedure. This control function is provided in the control device 6 a built in the control panel 6. Note that the return of the pallet traversing means onto the elevator 41 is detected by a rotary encoder connected to the driving motor of the traversing means. By this control, when the charging pallet 52A is stored in the charging parking portion 5A and the current collector 84 is in contact with the contact wire 62, no voltage is applied to the contact wire 62. Absent.

  Note that the general pallet 52B does not include the current collector 84, and has a shape that does not touch the contact wire 62 in other parts, so that it can be contacted even when stored in the charging parking portion 5A. There is no contact with the electric wire 62.

  Moreover, about the connection means of the current collector 62 which is the said contact electric wire 62 and the pallet side connection part, it is not limited to the thing by the said contact electric wire 62 and the current collector 84, For example, the pallet side and the parking shelf side Other methods such as a method of engaging / disengaging the connector with a solenoid or a method of bringing the power receiving side contact and the power feeding side contact into contact with each other on the pallet moving path of the parking unit 5 may be used.

  FIG. 5 is a front view showing an example of the operation panel in the multilevel parking facility shown in FIG. 1. As shown in the figure, a guide display unit 91 (for example, a liquid crystal display) is provided at the top of the operation panel 9 provided in the multi-story parking facility 1, and a “start” button 92, “empty call” is provided below the operation display unit 91. ”Button 93,“ cancel ”button 94,“ safety confirmation ”button 95,“ password ”button 96,“ end door close ”button 97, and“ door open ”button 98. At the side of these buttons, a numeric keypad 99 and a display unit 100 for “the number of empty vehicles” and “the number of warehousing” are provided. The numeric keypad 99 is used for inputting a pallet number for entering / exiting and a password.

  Below the display unit 100, there is provided a “confirmed number of warehousing / empty call” button 101 for selecting a vehicle to be stored. Below that, a “requires charge” button 102, a “charge not required” button 103, and A “re-entry” button 104 is provided. Further, at the bottom, a pre-preparation unit 105 provided with a “control power” key, an “operation mode” key, an “operation management” key, a standby mode selection key, and an “emergency stop” button is provided. Yes.

  FIG. 6 is a flowchart in the case where the full-time manager performs the warehousing operation of the multi-story parking facility shown in FIG. Based on this figure, the case where the said multistory parking equipment 1 is warehousing operation by a full-time manager is demonstrated. In the following description, the components shown in FIGS.

  The vehicle 7 is stopped in front of the entry / exit section 22 of the multi-story parking facility 1, and first the driving preparation is completed with the control panel “ON”, the operation mode “automatic”, and the operation management “dedicated” on the operation panel 9. (S1). Next, since it is time of warehousing, the “empty call” button 93 is pressed (S2), and the vehicle size (low vehicle height L such as a normal car, middle roof car, high roof, etc. is checked with the “number of warehousing / empty call” button 101 etc. A vehicle type selection condition such as a high vehicle height H) is input (S3). At this time, as the operation of the operation panel 9, for example, in the case of a fixed contract, the ID of the user or the contracted parking section is input with the numeric keypad 99.

  In order to omit this button operation, the vehicle size and other unique information may be input only by inputting by a card input means (not shown). In this case, since the contracted parking part (or pallet) is specified, it can be automatically determined from the state of the empty vehicle / actual vehicle, so it is not always necessary to select another entry / exit. .

  If the vehicles to be stored in the multi-story parking facility 1 are electric vehicles 7A (L) and 7A (H) and charging is required, the “require charge” button is used in the operation of the operation panel 9 when starting the storage. 102 is pressed (S4), and a condition such as the scheduled delivery time is added and input using the numeric keypad 99 (S5).

  In this example, whether or not charging is required is input on the operation panel 9 at the time of warehousing. Instead of inputting whether or not charging is required on the operation panel 9, the above-described connector 83 is connected to the battery side connecting portion. 72, it may be determined that charging is necessary. For this determination, a separate sensor may be provided in the connector 83 to detect the connection, or the charger 61 may detect that the circuit from the connector 83 is closed and determine the connection.

  In this way, the user does not need to perform any special operation as to whether or not charging is necessary, so that the complexity of the input is eliminated and an input error (for example, the state of the battery side connection unit 72 and the input of whether or not charging is necessary) It is possible to prevent troubles such as “they do not match” and “the connector is not charged even though it is inserted” due to an operation error.

  In addition, the necessity of charging is, for example, the case where charging is always necessary when all the pallets are stored in the charging pallet, or the case where it is clear that charging is always performed because the pallet is specified by contract. In the case where there is no need to input, and in the case of a specific business type where the form of entering the warehouse and leaving the next morning is almost unchanged, it is not limited to the above flow, such as the entry of the scheduled delivery time being unnecessary. .

  When the scheduled delivery time is input as described above, in this embodiment, whether or not charging is possible is confirmed (S6). In the confirmation of whether or not charging is possible, the determination that charging is possible is a case where the total of the number of units waiting for charging and their required charging time is short with respect to the time between the scheduled delivery time and the current time. It is determined as “possible” when there is a free space. In other words, it is “possible” in the case of ((scheduled shipping time−current time−required charging time) ≧ (number of waiting for charging × required charging time) and availability of charging pallet).

  If it is determined as “impossible” in this chargeability confirmation, it is announced that “cannot be charged before the departure time”, and by changing the departure time, stopping the entry, or pressing the “recharge unnecessary” button 103 ( S7) The warehousing operation can be continued. Thereafter, after confirming the safety of the surroundings, the “start” button 92 is pressed (S8), and the entry is started. When it is determined that charging is possible in the above chargeability confirmation, the “start” button 92 is then pressed. When selecting the above-mentioned warehousing cancellation, the “cancel” button 94 is pressed (S9) and the process is terminated.

  When entry is started by the above operation, the control device 6a, based on the input conditions, the parking portions 5A, 5B (height L or height if the vehicle 7A (L) is suitable for the vehicle height of the vehicle. The pallet 52 that is not mounted (the vacant) of the vehicle 7A (H) is transferred from the stored parking unit 5 to the lifting platform 41. .

  The pallet 52 taken out to the loading / unloading unit 22 for the warehousing becomes the charging pallet 52A when the electric vehicles 7A (L) and 7A (H) need to be charged. The parking part 5A or the general parking part 5B may be used. Furthermore, when the electric vehicle 7A (L), 7A (H) is not used, or when the electric vehicle 7A (L), 7A (H) does not require charging, the pallet 52B for general use is preferentially used, but there is a vacancy. If not, the charging pallet 52A may be used.

  Next, the elevator 41 is lowered to the lowest loading / unloading unit 22 to open the loading / unloading port. As a result, the user causes the electric vehicles 7A (L) and 7A (H) to self-propel and are mounted on the pallet 52. And when it is necessary to charge the battery 71 of the mounted electric vehicles 7A (L) and 7A (H), the connector 83 of the charging side connecting portion 8 is connected to the battery side of the electric vehicles 7A (L) and 7A (H). Connect to connection 72. At this time, if it is necessary to switch to the charging standby state on the vehicle side, it is appropriately performed.

  Thereafter, the pallet 52 on which the electric vehicles 7A (L) and 7A (H) are mounted is moved to the side of the vacant parking part 5 and the elevator 41 is moved to the parking shelf 51 together with the pallet 52 for storage. Is done.

  The “vacant parking unit 5”, which is the storage destination of the pallet 52 on which the vehicle 7 is mounted, includes the parking unit 5 as described above in addition to the original parking unit 5 from which the pallet 52 to be stored is taken out. Since the total number of pallets 52 is one less than the number of pallets 52, one vacant parking part 5 may be used. When charging is required for the electric vehicles 7A (L) and 7A (H) and at least one of the vacant parking portions is the charging parking portion 5A, it is immediately stored in the charging parking portion 5A. But you can start charging. Conversely, when the electric vehicle is not 7A (L), 7A (H) or when the electric vehicle 7A (L), 7A (H) does not require charging, the other electric vehicles 7A (L), 7A (H) It is desirable to store in the general parking part 5B in preparation for charging. In addition, when all the vacant parking parts 5 are the charging parking parts 5A, even if it is stored there, the pallet 52B is not energized as described above, and even when the pallet 52A is used, the connector Is not connected, so there is no problem.

  When the warehousing is completed in this way, the number of the parking area by the warehousing work, information input at the time of warehousing, and the like are stored in the control device 6a.

  FIG. 7 is a flowchart when the driver himself enters the multilevel parking facility shown in FIG. 1. When the driver himself operates the multilevel parking facility 1 as shown in FIG. After “Preparation for operation” (S1), a personal identification number is input (S10), and pallet number assignment is performed (S11). As the pallet number assignment, confirmation as to whether the user is a contractor, search for a contract pallet number or assignment of an available pallet as needed, determination of an electric vehicle user, and the like are performed. If the user is an electric user, the process proceeds to the “A” position in FIG. 6. If not, the process proceeds to the “B” position in FIG. Others are the same as those in FIG.

  FIG. 8 is a flowchart at the time of delivery when the multilevel parking facility shown in FIG. 1 is leased / fixed for a time, and FIG. 9 is a flowchart showing the driving operation after entering / exiting in the multilevel parking facility shown in FIG. It is. In this example, for example, a fixed contract such as a condominium and a time-rented parking lot where a storage vehicle is not fixed are exemplified.

  In this case, a number is entered after the start (S20). As this number input, the pallet number displayed in the “call number” window at the time of warehousing in the case of time lending, and the personal identification number in the case of a fixed contract are input.

  By this number input, “pallet number assignment” is performed (S21), and it is determined whether charging is necessary. If charging is necessary, it is determined whether or not charging is completed. If charging is not completed, a message “charging is not completed” is displayed on the guidance display unit 91, and re-entry is performed. A determination is made as to whether or not to do so. In the case of re-entry, the “re-entry” button 104 is pressed (S22). When the charging is not necessary and when the re-entry is not performed, when the “start” button 92 is pressed (S23), the vehicle that has been stored is placed in the loading / unloading unit 22, so that the user gets into the vehicle. You can get on.

  As shown in FIG. 9, at the completion of entry and entry, safety confirmation around the loading / unloading section is performed (S30), and if safe, by pressing the “safety confirmation” button 95 (S31), The safety lock is released (S32), and the “end door close” button 97 is pressed (S33), thereby completing a series of entry / exit operations.

  The above driving operation method is an example, and in addition to these, the driving operation method is not uniform depending on whether or not the power charge related to charging is individually measured and collected, and is limited to the above embodiment. is not.

  FIG. 10 is a flowchart showing a flow of charging the electric vehicle in the multilevel parking facility shown in FIG. The multi-story parking facility 1 is controlled so that the charging pallet 52A is replaced and charged to the electric vehicles 7A (L) and 7A (H) sequentially at an appropriate timing during standby. Hereinafter, an example of a procedure for replacing and charging the electric vehicles 7A (L) and 7A (H) that have been received will be described.

  As shown in the figure, it is first determined whether or not there is an empty space in the charging parking portion 5A (S40), and if there is, it is determined whether or not there is waiting for charging (S41).

  And in this embodiment, after the height of the vacant charge parking part 5A is determined (S42), it is determined whether there are a plurality of charging waits for each height of the charge parking part 5A. (S43). If there are a plurality of charging waits in this determination, the vehicle with the earliest scheduled time for delivery is selected (S44), and the vehicle is moved to the charging parking portion 5A (S45). In the selection of the vehicle with the earliest scheduled delivery time (S44), if the vacant charging parking portion 5A is in a high space H, the vehicle moves in both of the electric vehicles 7A (L) and 7A (H). In the case of the low space L, only the electric vehicle 7A (L) is moved.

  Thereafter, the charging pallet 52A on which the electric vehicles 7A (L) and 7A (H) are mounted is moved to the charging parking portion 5A and “charging start” is performed (S46). In this embodiment, as described above, when the charging pallet 52A is stored in the charging parking portion 5A, the contact wire 62 that is the parking portion side connecting portion and the current collector 84 that is the pallet side connecting portion Arc discharge and the like at the time of contact are prevented. In other words, this energization start is performed at another timing delayed from the connection of the parking part side connection part and the pallet side connection part, and the damage and deterioration of the equipment due to the discharge and inrush voltage when the connection means come into contact. It is preventing.

  Then, “end of charging” is detected (S47). In this embodiment, the end of charging is performed under the condition that the control device (control panel 6) ends the energization, that a predetermined time has elapsed since the start of energization, and that a warehousing call is issued to the pallet being charged. It is any one or any combination of being applied and that the charging current (or voltage) has reached a predetermined value. Even at the end of the energization, the energization is terminated at another timing before the parking portion side connection portion and the pallet side connection portion are separated to prevent discharge or the like when the connection means is separated.

  In addition, when the energization end condition is that a predetermined time has elapsed since the start of energization, the charger 61 is a quick charger, and the standard quick charge time is, for example, 15 minutes. A function that is known in advance and automatically stops charging so that the charger 61 itself detects it and does not become overcharged even if the battery charge amount of the vehicle to be charged before charging remains to some extent and the charging is completed early. , The control device 6a of the multi-story parking facility 1 may determine and execute the end of charging independently without acquiring information from the charger. However, even if the charger does not have an automatic stop function, there is no problem as long as it is a battery that does not cause inconvenience due to disconnection of the connection portion while energized, or an excessive time that does not cause inconvenience. Further, if the standard charging time is not so long, even if the actual charging is completed and there is a waiting time as it is, the decrease in the rotation rate of the electric vehicle waiting for charging is not a problem.

  In addition, if it is a condition for the end of energization that a call to leave for a pallet that is being charged, if the user prioritizes the use of the car over charging, the energization is immediately terminated in response to the call for leaving. And by continuing to issue, it is possible to prevent the user from stagnation in car use. On the other hand, if priority is given to charging, this condition is not applied, and a response indicating that “charging is not completed” is displayed on the guidance display unit 91 in response to the “call out”, and the product is left waiting for charging. Should be done.

  Further, when the charging current (or voltage) has reached a predetermined value as a condition for the end of energization, the charger 61 or the control device 6a monitors the charging current (or charging voltage) and has reached the predetermined value. Since the charging is terminated at the time, the battery 71 is not overcharged, and conversely, the battery 71 is not insufficiently charged, so that appropriate charging can be performed. This is because it is effective to control the end of energization under such conditions because lithium ion batteries, which are currently becoming mainstream, generate heat due to overcharging.

  In addition to the above conditions, the battery temperature and the temperature in the parking tower may be added to the conditions for starting and ending energization. According to these conditions, secondary batteries such as lithium ion batteries are effective because they are known to generate heat when charged, or to cause deterioration of the battery or a decrease in charge capacity due to the influence of the ambient temperature. . The determination of “end of charging” may be, for example, simply a pallet staying time in the charging parking portion 5A, or may be treated as end of charging as described later, or may be performed by other methods. .

  It should be noted that these conditions are not limited to being applied singly, but may be combined with each other (for example, the elapsed time or the predetermined voltage, whichever comes first), or other conditions, for example, conditions entered at the time of warehousing ( For example, the upper limit of the electricity charge may be added to the determination, or energization may be performed only during the midnight fee contract time.

  Thereafter, the electric vehicles 7A (L) and 7A (H) that have been charged are moved to the general parking unit 5B (S48).

  When the charging of one electric vehicle 7A (L), 7A (H) is completed in this way, the process returns to the determination of whether or not waiting for charging, and corresponds to the electric vehicles 7A (L) and 7A (H) waiting for charging. The electric vehicles 7A (L) and 7A (H) are sequentially transferred to the charging parking portion 5A, and charging is performed sequentially.

  In this way, the charging operation is performed based on the information stored in the control device 6a based on the information stored in the control device 6a in advance when the necessity of charging is entered in the operation panel 9 at the time of warehousing. Priority is given from the number of electric vehicles 7A (L), 7A (H) that need charging and their respective scheduled delivery times. Electricity is sequentially applied between the charging parking unit 5A and the general parking unit 5B. The charging pallet 5A on which the automobiles 7A (L) and 7A (H) are mounted is replaced and charging is completed sequentially.

  As an example of the actual pallet replacement operation, when transferring from the charging parking unit 5A to the general parking unit 5B, the elevator 41 is moved to the side of the parking unit 5A in the same manner as the operation at the time of warehousing. After 52A is transferred onto the lifting platform 41, the lifting platform 41 is moved to the side of the general parking unit 5B as the movement destination, and then the entire pallet 52A is transferred to the parking shelf 51 to complete the replacement operation. The replacement operation from the general parking unit 5B to the charging parking unit 5A is the reverse procedure.

  When the vehicle is to be delivered, the elevator 41 is moved to the side of the vehicle to be delivered, and then the vehicle is transferred from the parking shelf 51 to the elevator 41 together with the pallet 52. The vehicle is taken out by being lowered to the loading / unloading unit 22. At this time, if the vehicle is an electric vehicle 7A (L) or 7A (H) that needs to be recharged, if the vehicle arrives at the loading / unloading unit 22 and then exits by itself, if necessary After performing the switching operation with respect to the vehicle, the connection between the connector 83 of the charging side connecting portion 8 and the battery side connecting portion 72 of the electric vehicles 7A (L) and 7A (H) is released.

  On the other hand, the multi-story parking facility 1 according to the present invention has a number of pallets that is one or more less than the total number of parking units 5, so that there is always a free parking unit 5. For this reason, when a certain pallet is transferred to another parking part 5 by using this vacant parking part 5, the pallet in the destination parking part 5 is first transferred to the vacant parking part. The storage position can be changed by a procedure of transferring the target pallet here and further transferring the pallet once transferred to the empty parking unit 5 to the parking unit 5 of the movement source.

  Therefore, during the waiting time of the multi-story parking facility 1, the actual vehicle pallets are collected in the low-rise parking part 5 near the entrance / exit, and the empty vehicle pallets are entered / exited prior to the time when the entry is concentrated. It can also be collected near the mouth. In this way, the pallet 52 is moved during the waiting time of the multi-story parking facility 1 to shorten the time for warehousing and delivery, and the normal vehicle of the parking part 5 in the high space H where a high roof car or the like can be parked is low space. You may add to the control apparatus 6a the function which moves to the parking part 5 of L and uses the parking part 5 of the high space H effectively. In the case of the multilevel parking facility 1 of the above embodiment, since a vehicle with a high vehicle height and a vehicle with a low vehicle height are mixedly loaded, in order to make it possible to replace all, What is necessary is just to make it the parking part 5 for high cars so that a car with a high vehicle height and a car with a low vehicle height can be deposited temporarily.

  Furthermore, by using the guidance display unit 91 provided on the operation panel 9, the parking area number stored at the time of warehousing is linked with the information on the completion of energization (charging completion), and various messages are displayed when calling out. You may make it display. For example, if charging is not completed, and the reason is displayed together with the reason for the charging result, the user can know the charging result before boarding and can quickly respond to the result. it can. That is, when a call to leave takes place before charging is completed, or when charging is not completed due to the battery temperature, such information is known on the multi-story parking facility 1 side. By displaying the reason, it is possible for the user to check the charging result before boarding and determine whether it can be charged if re-entry. If it is a short distance, it is possible to quickly select whether or not to travel the required distance with the remaining charge amount.

  As described above, according to the multilevel parking facility 1, the charging pallet 52 </ b> A is provided in a number corresponding to the number of the charging parking units 5 </ b> A provided with the charging facility, and the connector 83 provided in the charging pallet 52 </ b> A at the time of warehousing. The electric vehicle 7A (L), 7A (H) in the charging parking portion 5A can be used only when the electric vehicle 7A (L), 7A (H) is connected to the battery-side connecting portion 72, when the storage / exit is quiet. After the completion of charging, the charging pallet 52A of the other parking unit 5 can be replaced and automatically charged to a plurality of electric vehicles 7A (L) and 7A (H). Can be effectively used to charge a large number of electric vehicles 7A (L) and 7A (H), and the convenience for charging can be improved while reducing cost and space.

  In other words, by reducing the number of expensive and space-consuming chargers and increasing the operating rate of the charger 6, the charging facilities are minimized, and the efficiency of many electric vehicles 7A (L) and 7A (H) is improved. It can charge well. In addition, even existing multi-story parking facilities that do not have a charging function can be easily modified to have a charging function.

  In addition, in the said embodiment, although the elevator-type three-dimensional parking equipment 1 was demonstrated to the example, if it is the three-dimensional parking equipment of the arbitrary systems which store a pallet in a parking shelf with a conveyance apparatus, it can apply similarly. For example, an elevator slide system, a plane reciprocating system, and the like can be similarly applied to a multi-level parking facility configured to store a pallet in a charging parking rack.

  In addition, the position of the parking part 5 is not limited to the upper part of the entrance / exit, and the number thereof can be freely increased and decreased, and may be installed in a space provided in a building for dwelling units instead of a dedicated parking wing, It is not limited to this embodiment.

  Furthermore, in accordance with the degree of popularization of electric vehicles, initially, the multi-story parking facility 1 is provided with a minimum number of charging parking portions 5A and charging pallets 52A. By replacing the pallet 52A for use and reducing the total number of pallets to one and changing the configuration as described above, both the initial cost and the remodeling cost can be suppressed.

  The above-described embodiment shows an example, and various modifications can be made without departing from the gist of the present invention. The present invention is not limited to the above-described embodiment.

  The multi-story parking facility having a charging function according to the present invention can be used in a multi-story parking facility that wants to efficiently charge an electric vehicle that needs to be charged using the time during parking.
