Description

本発明は、機械式駐車設備において駐車中の複数の電気車両に充電するための充電制御方法とその制御装置に関する。   The present invention relates to a charging control method for charging a plurality of electric vehicles parked in a mechanical parking facility, and a control device therefor.

従来、車両を駐車させる機械式駐車設備として、エレベータ式、平面往復式、縦横パズル移動式、多段式等、種々の駐車装置が設置条件等に応じて利用されている。   Conventionally, as a mechanical parking facility for parking a vehicle, various parking apparatuses such as an elevator type, a plane reciprocating type, a vertical and horizontal puzzle moving type, and a multistage type are used according to installation conditions and the like.

一方、近年、電動機を動力源とした電気車両(この明細書及び特許請求の範囲の書類中における「電気車両」は、電動モータの動力(エンジンの併用を含む)で走行することのできるものをいう)が普及している。このような電気車両は排気ガス量を減らせるので環境保全上優れているが、従来の燃料の代わりに電気を蓄電池(バッテリ)に充電する必要がある。そのため、上記したような駐車装置に格納している時間を利用して充電しようとする充電機能付きの駐車装置が発明されている。このような駐車装置では、一般的に、パレットに電気車両を搭載し、そのパレットを格納した駐車部で搭載した電気車両の充電を行っている。   On the other hand, in recent years, an electric vehicle using an electric motor as a power source (an “electric vehicle” in the specification and claims is a vehicle that can be driven by electric motor power (including combined use of an engine)). Say) is popular. Such an electric vehicle is excellent in environmental conservation because it can reduce the amount of exhaust gas, but it is necessary to charge electricity to a storage battery (battery) instead of conventional fuel. Therefore, a parking device with a charging function that attempts to charge using the time stored in the parking device as described above has been invented. In such a parking apparatus, generally, an electric vehicle is mounted on a pallet, and the electric vehicle mounted in a parking unit storing the pallet is charged.

このように電気車両を駐車部で充電する先行技術として、駐車パレットの移動用の駆動電源を電源として駐車した電気車両に給電し得る充電器と、駐車パレットの移動時には充電器から車両への給電を阻止する給電阻止手段を設け、駐車機の動力用電源から開閉器を介し電気車両充電用電源を取り出すようにした充電システムがある(例えば、特許文献1参照)。   Thus, as a prior art for charging an electric vehicle at a parking unit, a charger that can supply power to a parked electric vehicle using a driving power source for moving a parking pallet, and power supply from the charger to the vehicle when the parking pallet moves There is a charging system provided with a power supply blocking means for blocking the electric vehicle and taking out the electric vehicle charging power source from the power source for the parking machine via a switch (see, for example, Patent Document 1).

ところで、上記機械式駐車設備に用いられる動力用電源は、通常、三相交流電源(以下、単に「三相電源」ともいう)であるのに対し、電気自動車の充電用電源は一般的に単相電源である。そのため、機械式駐車設備に電気車両充電用の単相専用電線を引き込むことが考えられるが、その場合には、機械式駐車設備の一次側電源設備の規模を大きくする必要があり、施工時の初期費用が増大する。しかも、電気料金の基本料金が上がって維持費用も増大する。   By the way, the power source for power used in the mechanical parking facility is usually a three-phase AC power source (hereinafter, also simply referred to as “three-phase power source”), whereas the power source for charging an electric vehicle is generally a single unit. Phase power supply. Therefore, it is conceivable to draw a single-phase electric wire for charging an electric vehicle into the mechanical parking facility, but in that case, it is necessary to increase the scale of the primary power supply facility of the mechanical parking facility, Initial costs increase. In addition, the basic cost of electricity increases and maintenance costs increase.

さらに、既設の機械式駐車設備では既存の電源設備を増強することが困難な場合が多く、充電機能を備えさせるためにはより多くの施工費用が必要となるおそれがある。このようなことから、機械式駐車設備に用いられている三相電源から電気車両用の単相電源を取り出すことが考えられる。   Furthermore, it is often difficult to reinforce existing power supply facilities with existing mechanical parking facilities, and there is a possibility that more construction costs may be required to provide a charging function. For this reason, it is conceivable to take out a single-phase power source for an electric vehicle from a three-phase power source used in a mechanical parking facility.

なお、三相交流電源から、位相バランスを崩すことなく複数の直流電源変換用に二相を取り出す場合の接続方法として、三相分の配線のうち二相分をクロスして配線し、クロスした配線の一方とクロスしなかった残りの一相分の配線に直流用電源接続用の配線を接続するようにしたものがある(例えば、特許文献2参照)。   In addition, as a connection method when two phases are taken out from a three-phase AC power source for a plurality of DC power source conversions without losing the phase balance, the two phases of the three-phase wiring are crossed and wired. There is one in which a wiring for connecting a DC power supply is connected to a wiring for the remaining one phase that does not cross one of the wirings (for example, see Patent Document 2).

特許第2753770号公報Japanese Patent No. 2753770 特開2006−228100号公報JP 2006-228100 A

ところで、上記特許文献1のように開閉器を介して三相電源から単相の電源を取り出す場合、図4に示すように、複数の電気車両EV1〜EVnを電磁接触器100〜105の接点(A1,B1)〜(An,Bn)を介して三相電源106の第一相(R)、第二相(S)、及び第三相(T)の何れか二相に固定的に接続することになる。   By the way, when taking out a single-phase power supply from a three-phase power supply via a switch like the said patent document 1, as shown in FIG. 4, several electric vehicles EV1-EVn are contacted | contacted with the electromagnetic contactors 100-105 ( It is fixedly connected to any one of the two phases of the first phase (R), the second phase (S), and the third phase (T) of the three-phase power source 106 through A1, B1) to (An, Bn). It will be.

しかしながら、このような二相の固定的な接続を行うと、図示するように、三相電源の第一相(R)と第二相(S)に接続された数台の電気車両(この図では、EV1,EV4)の電磁接触器100,104の接点(A1,B1),(A4,B4)のみが接続されて充電される状態を生じる場合があり、このような場合には、第一相(R)と第二相(S)とに負荷が片寄って「三相回路の不平衡(アンバランス)」を生じてしまう。   However, when such a two-phase fixed connection is made, as shown in the drawing, several electric vehicles connected to the first phase (R) and the second phase (S) of the three-phase power supply (this figure) Then, only the contacts (A1, B1), (A4, B4) of the electromagnetic contactors 100, 104 of EV1, EV4) may be connected and charged, and in such a case, the first The load is shifted between the phase (R) and the second phase (S), resulting in a “three-phase circuit unbalance”.

この「三相回路の不平衡」を生じないように三相電源に単相負荷を接続する場合、3つの相にバランスよく負荷を接続する必要がある。そのため、上記特許文献2のように三相の配線をクロス接続することで電気車両を三相回路にバランス良く振り分けて接続することも考えられる。しかし、多数(例えば、4台以上)の電気車両に充電する場合、複数の電気車両が同時に充電されるとは限らず、電気車両の充電状況によっては接続される電磁接触器の接点(A1,B1)〜(An,Bn)が変化して、三相回路全体で常にバランスを保つことは困難である。   When a single-phase load is connected to the three-phase power supply so as not to cause this “three-phase circuit unbalance”, it is necessary to connect the load to the three phases in a balanced manner. Therefore, it is also conceivable to distribute and connect the electric vehicle to the three-phase circuit in a well-balanced manner by cross-connecting the three-phase wirings as in Patent Document 2. However, when charging a large number (for example, four or more) of electric vehicles, a plurality of electric vehicles are not always charged at the same time. B1) to (An, Bn) change, and it is difficult to always keep the balance in the entire three-phase circuit.

このように、駐車設備の三相電源から電気車両充電用単相電源を取り出す場合には上記「三相回路の不平衡」は避けられず、充電する電気車両EVの相接続が片寄ってアンバランスになることに伴って種々の障害を生じる。この障害としては、例えば、三相機器(立駐用モータ)の騒音、相ずれによるモータ回転不良、電力量計の回転過剰(電力料金の増加)、一次側変圧器の温度上昇等を生じる。   As described above, when the electric vehicle charging single-phase power source is taken out from the three-phase power source of the parking facility, the above-mentioned “three-phase circuit imbalance” is unavoidable, and the phase connection of the electric vehicle EV to be charged is shifted and unbalanced. As a result, various obstacles occur. Examples of the obstacle include noise of a three-phase device (stationary motor), motor rotation failure due to a phase shift, excessive rotation of a watt hour meter (increase in electric charge), temperature increase of a primary side transformer, and the like.

そこで、本発明は、機械式駐車設備における三相電源によって複数の充電用単相電源をバランス良く取り出すことができる充電制御方法と、その制御装置を提供することを目的とする。   Then, an object of this invention is to provide the charge control method which can take out several single-phase power supply for charge with a three-phase power supply in a mechanical parking installation with sufficient balance, and its control apparatus.

上記目的を達成するために、本発明の機械式駐車設備における充電制御方法は、機械式駐車設備の動力用三相電源から複数の電気車両充電用単相電源を取り出すための機械式駐車設備における充電制御方法であって、前記三相電源から前記単相電源の二相を取り出すように組合わせた各々の電磁接触器の接点を、複数の電気車両の充電に対応した駐車棚における充電状況を前記電磁接触器を流れる電流値を電流検出器で監視して電流バランスが悪化しないように三相電源の各相の組み合わせ数を比較して、新たな電気車両の充電に対応した駐車棚における接続時には全ての電磁接触器における組み合わせ数の小さい組み合わせの相を選択するように各電磁接触器の接点を選択して切り替えることで三相電源の二相を選択するように制御することを特徴とする。この明細書及び特許請求の範囲の書類中における「電磁接触器」は、三相電源の各相に接点が接続される開閉器等をいう。これにより、機械式駐車設備の動力用三相電源から複数の電気車両充電用単相電源の二相を取り出しても、複数の電気車両の充電に対応した駐車棚の充電状況を監視して、新たな電気車両の充電に対応した駐車棚における接続時には全ての電磁接触器における組み合わせ数の小さい組み合わせの相を選択するように各電磁接触器の接点を切り替えることで電流バランスが悪化するのを抑え、「三相回路の不平衡」という現象を最小限に抑えることができる。しかも、簡単な構成で電気車両の充電状況を監視して電流バランスの悪化を抑えることができる。 In order to achieve the above object, a charge control method for a mechanical parking facility according to the present invention is a mechanical parking facility for extracting a plurality of single-phase power sources for charging an electric vehicle from a power three-phase power source for the mechanical parking facility. A charging control method, wherein the contact state of each electromagnetic contactor combined so as to take out two phases of the single-phase power source from the three-phase power source is charged in a parking shelf corresponding to charging of a plurality of electric vehicles. The current value flowing through the electromagnetic contactor is monitored by a current detector, and the number of combinations of each phase of the three-phase power supply is compared so that the current balance does not deteriorate, and the connection in the parking shelf corresponding to the charging of a new electric vehicle control child to select a two-phase of the three-phase power supply by switching sometimes all the number of combinations of small combinations of phases in the electromagnetic contactor by selecting contacts each of the electromagnetic contactor to select The features. “Electromagnetic contactor” in the specification and claims refers to a switch or the like in which a contact is connected to each phase of a three-phase power source. Thereby, even if two phases of a plurality of single-phase power sources for charging electric vehicles are taken out from the three-phase power source for power of mechanical parking equipment, the charging status of the parking rack corresponding to the charging of the plurality of electric vehicles is monitored , Prevents current balance from deteriorating by switching the contacts of each electromagnetic contactor to select a combination phase with a small number of combinations in all electromagnetic contactors when connected in a parking shelf that supports charging of new electric vehicles The phenomenon of “three-phase circuit imbalance” can be minimized. In addition, the charging status of the electric vehicle can be monitored with a simple configuration, and deterioration of the current balance can be suppressed.

また、前記電磁接触器による三相電源の二相を選択する切り替えを、前記電気車両の充電に対応した駐車棚における1〜3台目は三相電源の各相を振り分けた「RS」接続、「RT」接続、「ST」接続の各二相に接続される電磁開閉器に接続し、前記電気車両の充電に対応した駐車棚における4台目以降においては相選択用開閉器で電流バランスが悪化しない二相を選択するように接点を切り替えて接続するようにしてもよい。このようにすれば、3台目までの充電に対応した駐車棚は各相にバランス良く振り分けて接続することで充電に制御を要しないようにし、4台目以降の相選択で駐車設備における電流バランスが悪化するのを抑えることで、電流バランスの制御を容易に行うことができる。 In addition, switching to select two phases of the three-phase power supply by the electromagnetic contactor, the first to third in the parking rack corresponding to the charging of the electric vehicle is an “RS” connection that distributes each phase of the three-phase power supply , It is connected to the electromagnetic switch connected to each of the two phases of “RT” connection and “ST” connection , and the current balance is provided by the phase selection switch in the fourth and subsequent cars in the parking rack corresponding to the charging of the electric vehicle. exacerbated not biphasic it may be so that connect to switch the contacts so as to select. In this way, the parking shelves that support charging up to the third unit are distributed and connected in a balanced manner to each phase so that control is not required for charging, and the current in the parking facility can be selected by selecting the fourth and subsequent units. By suppressing the deterioration of the balance, it is possible to easily control the current balance.

さらに、前記機械式駐車設備の動力源が駆動されている時には前記電磁接触器の接点を開放するようにしてもよい。このようにすれば、機械式駐車設備の動力源の駆動(例えば、エレベータ式駐車設備における搬器の昇降駆動等)と電気車両の充電とが同時に行われないようにして、駐車設備の電源容量を抑えて充電制御が行えるようにできる。   Furthermore, the contact point of the electromagnetic contactor may be opened when the power source of the mechanical parking facility is being driven. In this way, the power supply capacity of the parking facility can be reduced by preventing the driving of the power source of the mechanical parking facility (for example, raising and lowering the elevator in the elevator parking facility) and charging the electric vehicle at the same time. It is possible to control charging while suppressing it.

一方、本発明の機械式駐車設備における充電制御装置は、機械式駐車設備の動力用三相電源から各々の電磁接触器を介して複数の電気車両充電用単相電源を取り出すための機械式駐車設備における充電制御装置であって、前記電磁接触器は、複数の電気車両の充電状況を前記電磁接触器を流れる電流値を電流検出器で監視して電流バランスが悪化しないように三相電源の各相の組み合わせ数を比較して、新たな電気車両の充電に対応した駐車棚における接続時には全ての電磁接触器における組み合わせ数の小さい組み合わせの相を選択するように各電磁接触器の接点を選択して切り替えることで三相電源の二相を選択する制御装置で制御されるように構成されていることを特徴とする。これにより、機械式駐車設備の動力用三相電源から複数の電気車両充電用単相電源の二相を取り出しても、複数の電気車両の充電に対応した駐車棚の充電状況を監視して、新たな電気車両の充電に対応した駐車棚における接続時には全ての電磁接触器における組み合わせ数の小さい組み合わせの相を選択するように各電磁接触器の接点を切り替えることで電流バランスが悪化するのを抑え、「三相回路の不平衡」という現象を最小限に抑えることができる。しかも、簡単な構成で電気車両の充電状況を監視して電流バランスの悪化を抑えることができる。 On the other hand, the charge control device in the mechanical parking facility of the present invention is a mechanical parking device for taking out a plurality of single-phase power sources for charging an electric vehicle from the three-phase power source for power of the mechanical parking facility via each electromagnetic contactor. A charging control device for equipment, wherein the electromagnetic contactor is a three-phase power source so that a current detector monitors a charging state of a plurality of electric vehicles with a current detector to prevent a current balance from deteriorating. Compare the number of combinations of each phase, and select the contact point of each electromagnetic contactor so that the combination phase with a small number of combinations in all the electromagnetic contactors is selected when connected in the parking rack that supports charging of a new electric vehicle It is configured to be controlled by a control device that selects two phases of a three-phase power source by switching between them. Thereby, even if two phases of a plurality of single-phase power sources for charging electric vehicles are taken out from the three-phase power source for power of mechanical parking equipment, the charging status of the parking rack corresponding to the charging of the plurality of electric vehicles is monitored , Prevents current balance from deteriorating by switching the contacts of each electromagnetic contactor to select a combination phase with a small number of combinations in all electromagnetic contactors when connected in a parking shelf that supports charging of new electric vehicles The phenomenon of “three-phase circuit imbalance” can be minimized. In addition, the charging status of the electric vehicle can be monitored with a simple configuration, and deterioration of the current balance can be suppressed.

また、前記電磁接触器は、前記電気車両充電用単相電源の二相を取り出す1〜3台目の充電に対応した駐車棚は三相電源の各相を振り分けた「RS」接続、「RT」接続、「ST」接続の各二相に接続される電磁開閉器で構成され、4台目以降の充電に対応した駐車棚は前記三相電源から二相を取り出す全ての組み合わせを有する相選択用開閉器で構成されていてもよい。この明細書及び特許請求の範囲の書類中における「相選択用開閉器」は、三相電源の二相を選択的に接続することができる開閉器をいう。このようにすれば、3台目までの充電に対応した駐車棚は各相に振り分けて接続することで充電に制御を要しないようにし、4台目以降の相選択で駐車設備における電流バランスが悪化するのを抑えることで、電流バランスの制御を容易に行うことができる。 In addition, the electromagnetic contactor takes out the two phases of the electric vehicle charging single-phase power supply, the parking shelf corresponding to the first to third charging has an “RS” connection that distributes each phase of the three-phase power supply , and “RT Phase selection with a combination of electromagnetic switches connected to each of the two phases of the "connection" and the "ST" connection, the parking racks corresponding to the fourth and subsequent charging having all combinations of taking out the two phases from the three-phase power source You may be comprised with the switch for the purpose. The term “phase selection switch” in this specification and claims refers to a switch that can selectively connect two phases of a three-phase power source. In this way, parking shelves that support charging up to the third vehicle are distributed and connected to each phase so that control is not required for charging, and the current balance in the parking facility is selected by phase selection after the fourth vehicle. By suppressing the deterioration, the current balance can be easily controlled.

また、前記制御装置は、前記機械式駐車設備の動力源が駆動されている時には前記電磁接触器の接点を開放するように構成されていてもよい。このようにすれば、機械式駐車設備の動力源の駆動(例えば、エレベータ式駐車設備における搬器の昇降駆動等)と電気車両の充電とが同時に行われないようにして、駐車設備の電源容量を抑えて充電制御が行えるようにできる。   Moreover, the said control apparatus may be comprised so that the contact of the said electromagnetic contactor may be open | released when the power source of the said mechanical parking equipment is driven. In this way, the power supply capacity of the parking facility can be reduced by preventing the driving of the power source of the mechanical parking facility (for example, raising and lowering the elevator in the elevator parking facility) and charging the electric vehicle at the same time. It is possible to control charging while suppressing it.

本発明によれば、駐車設備の三相電源から電気自動車の単相電源を取り出しても三相回路の不平衡という現象を最小限に抑えることができるので、設備増強・施工費用を抑えて機械式駐車設備に充電機能を付加することが容易に可能となる。   According to the present invention, even if a single-phase power source of an electric vehicle is taken out from a three-phase power source of a parking facility, the phenomenon of unbalance of the three-phase circuit can be minimized, so that the equipment enhancement and construction costs can be reduced. It becomes easy to add a charging function to the parking system.

The elevator transporter 12 is moved up and down the hoistway 10 by a wire rope 15 wound around a drive sheave 14 of an elevating drive unit 13 provided at the upper part of the parking tower 2. On the side of the wire rope 15 opposite to the elevator, a counterweight 16 that reduces the hoisting force is provided.

さらに、エレベータ搬器12には、パレット20,90を持上げて旋回させる機能と、パレット20,90を上記駐車棚11の棚レール17との間で移載させる機能とを有するパレット移載兼持上げ旋回手段25が備えられている。各パレット20,90は、このパレット移載兼持上げ旋回手段25により、各駐車棚11とエレベータ搬器12との間を車輪24で移載されるとともに、乗入れ部3で旋回させられる。このパレット移載兼持上げ旋回手段25は、公知の手段が採用される。   Further, the elevator transporter 12 has a function of lifting and rotating the pallets 20 and 90 and a function of transferring and lifting the pallets 20 and 90 between the rack rails 17 of the parking rack 11.

For example, a trolley power supply system (for example, a trolley power supply system provided on either the parking shelf 11 side or the charging pallet 20 side so that a trolley power supply line and a movable current collector are paired, for example As this trolley power feeding method, Japanese Patent Application No. 2008-257635 filed earlier by the present applicant may be adopted) or other forms may be adopted.

また、上記充電パレット20には、コンセント52に接続された中継ケーブル53を格納するケーブル収納箱54が設けられており、この中継ケーブル53に接続された充電ケーブル55の充電アダプタ56が電気車両EVに接続されるようになっている。   The charging pallet 20 is provided with a cable storage box 54 for storing the relay cable 53 connected to the outlet 52, and the charging adapter 56 of the charging cable 55 connected to the relay cable 53 is connected to the electric vehicle EV. To be connected to.

図2に基いて上記駐車装置1の制御ブロックを説明する。この例では、1〜3台目の電気車両EV1〜EV3は、通常の開閉器30〜32によって三相電源の各相を組み合わせた配線(R,S,T)に接続されている。この例では、電気車両EV1の単相の2線が開閉器30の接点(A1,B1)を介して第一相(R)及び第二相(S)に接続され、電気車両EV2の単相の2線が開閉器31の接点(A2,B2)を介して第一相(R)及び第三相(T)に接続され、電気車両EV3の単相の2線が開閉器32の接点(A3,B3)を介して第二相(S)及び第三相(T)に接続されている。各相の配線は、上記開閉器30〜32の接点(A1,B1)〜(A3,B3)を開閉することによって接続/切断(ON/OFF)されるようになっている。   The control block of the parking apparatus 1 will be described with reference to FIG. In this example, the first to third electric vehicles EV1 to EV3 are connected to wiring (R, S, T) that combines the phases of the three-phase power supply by ordinary switches 30 to 32. In this example, the single-phase two wires of the electric vehicle EV1 are connected to the first phase (R) and the second phase (S) via the contacts (A1, B1) of the switch 30, and the single-phase of the electric vehicle EV2 Are connected to the first phase (R) and the third phase (T) via the contacts (A2, B2) of the switch 31, and the single-phase two wires of the electric vehicle EV3 are connected to the contacts ( It is connected to the second phase (S) and the third phase (T) via A3, B3). The wiring of each phase is connected / disconnected (ON / OFF) by opening / closing the contacts (A1, B1) to (A3, B3) of the switches 30-32.

そして、4台目以降の電気車両EV4〜EVnが、相選択用開閉器33によって三相電源から二相を取り出す全ての組み合わせの配線に接続されている。この例では、電気車両EV4の単相の一方の線が、相選択用開閉器33の接点(A4)を介して第一相(R)と接点(B4)を介して第二相(S)に接続されている。また、他方の線は、相選択用開閉器33の接点(C4)を介して第三相(T)と接点(D4)を介して第二相(S)に接続されている。このような接続は、電気車両EVnまで同一である。この相選択用開閉器33は、三相電源43の各相(R,S,T)を選択的に接続させる電磁開閉器であり、各相の選択的な接続は、相選択用開閉器33の接点(A4,B4,C4,D4)〜(An,Bn,Cn,Dn)を選択的に開閉することによって行われる。例えば、第一相(R)−第二相(S)接続(以下、単に「RS」接続ともいう)の時には接点A4,D4がON(接続)となり、第一相(R)−第三相(T)接続(以下、単に「RT」接続ともいう)の時には接点A4,C4が、第二相(S)−第三相(T)接続(以下、単に「ST」接続ともいう)の時には接点B4,C4がON(接続)となる。この電気車両EV4以降に接続される相選択用開閉器33は、全て同一の相接続であり、接点(A4,B4,C4,D4)〜(An,Bn,Cn,Dn)の開閉によって三相のいずれかの相接続が選択される。   The fourth and subsequent electric vehicles EV4 to EVn are connected to all combinations of wirings that take out the two phases from the three-phase power source by the phase selection switch 33. In this example, one single-phase line of the electric vehicle EV4 is connected to the first phase (R) via the contact (A4) of the phase selection switch 33 and the second phase (S) via the contact (B4). It is connected to the. The other line is connected to the third phase (T) via the contact (C4) of the phase selection switch 33 and the second phase (S) via the contact (D4). Such a connection is the same up to the electric vehicle EVn. The phase selection switch 33 is an electromagnetic switch that selectively connects each phase (R, S, T) of the three-phase power source 43. The selective connection of each phase is performed by the phase selection switch 33. The contacts (A4, B4, C4, D4) to (An, Bn, Cn, Dn) are selectively opened and closed. For example, when the first phase (R) -second phase (S) connection (hereinafter also simply referred to as “RS” connection), the contacts A4 and D4 are turned on (connected), and the first phase (R) -third phase When the (T) connection (hereinafter also simply referred to as “RT” connection), the contacts A4 and C4 are the second phase (S) -third phase (T) connection (hereinafter also simply referred to as “ST” connection). The contacts B4 and C4 are turned on (connected). The phase selection switches 33 connected after the electric vehicle EV4 are all in the same phase connection, and three-phase is established by opening and closing the contacts (A4, B4, C4, D4) to (An, Bn, Cn, Dn). Either phase connection is selected.

また、上記開閉器30〜32及び相選択用開閉器33と電気車両EV1〜EVnとの間の配線には、各電気車両EV1〜EVnの充電時に流れる電流値を検出する電流検出器CT1〜CTnが設けられている。これらの電流検出器CT1〜CTnによって検出された電流値は、後述するように電流監視装置35によって監視され、この電流値によって各電気車両EV1〜EVnが充電状態であるか否かが判断されるようになっている。   Further, current detectors CT1 to CTn for detecting current values flowing when the electric vehicles EV1 to EVn are charged are connected to the switches 30 to 32 and the phase selection switches 33 and the electric vehicles EV1 to EVn. Is provided. The current values detected by these current detectors CT1 to CTn are monitored by a current monitoring device 35, as will be described later, and whether or not each electric vehicle EV1 to EVn is in a charged state is determined based on this current value. It is like that.

そして、上記I/O装置には、上記各電気車両EV1〜EVnの充電を制御する充電制御部36(CPU)を備えた充電制御装置37が接続されている。この充電制御部36には、上記開閉器30〜32の各接点(A1,B1)〜(An,Bn)及び上記相選択用開閉器33の各接点(A4,B4,C4,D4)〜(An,Bn,Cn,Dn)を接続/切断(ON/OFF)する配線が接続されている。さらに、この充電制御部36には、上記各電流検出器CT1〜CTnで検出された電流値を監視する電流監視装置35が接続されている。この電流監視装置35は、電流が流れているか否かを監視する装置であり、例えば、所定のしきい値以上の電流が流れるているか否かを監視し、流れていれば「充電中」、流れていなければ「満充電」又は「電気車両非接続」と判断するようになっている。この電流監視装置35で各電気車両EV1〜EVnの充電時に流れる電流を監視し、充電制御部36によって後述するように充電制御される。   And the charge control apparatus 37 provided with the charge control part 36 (CPU) which controls charge of each said electric vehicle EV1-EVn is connected to the said I / O apparatus.

The current monitoring device 35 monitors the current that flows when the electric vehicles EV <b> 1 to EVn are charged, and the charging control unit 36 controls the charging as described later.

図3に示すように、上記エレベータ式駐車装置1による充電時の相選択フローチャートを以下に説明する。以下の説明では、三相電源43の各相(第一相(R)、第二相(S)、第三相(T))の記号を用いて説明する。なお、フローチャート中では、電気車両を「EV1〜EVn」で示す。また、以下の充電中であるか否かの判断は、上記電流検出器CT1〜CTnによって所定の電流値を検出しているか否かによって判断される。   As shown in FIG. 3, a phase selection flowchart during charging by the elevator parking device 1 will be described below. In the following description, description will be made using symbols of the respective phases (first phase (R), second phase (S), and third phase (T)) of the three-phase power source 43. In the flowchart, the electric vehicle is indicated by “EV1 to EVn”. Further, whether or not the following charging is being performed is determined by whether or not a predetermined current value is detected by the current detectors CT1 to CTn.

図示するように、まず、三相電源の各相の組合わせ(RS,RT,ST)における充電車両数のカウンタがクリアされる(S1)。   As shown in the drawing, first, the counter of the number of charged vehicles in the combination (RS, RT, ST) of each phase of the three-phase power supply is cleared (S1).

次に、電気車両EV1が充電中であるか否かが判断され(S2)、充電中であれば「RS=RS+1」と「RS」接続のカウンタに「+1」が入力される(S3)。この電気車両EV1の充電中が入力された後、又は上記電気車両EV1が充電中でない場合、電気車両EV2が充電中であるか否かが判断され(S4)、充電中であれば、「RT=RT+1」と「RT」接続のカウンタに「+1」が入力される(S5)。この電気車両EV2の充電中が入力された後、又は上記電気車両EV2が充電中でない場合、電気車両EV3が充電中であるか否かが判断され(S6)、充電中であれば、「ST=ST+1」と「ST」接続のカウンタに「+1」が入力される(S7)。   Next, it is determined whether or not the electric vehicle EV1 is being charged (S2). If the electric vehicle EV1 is being charged, “RS = RS + 1” and “+1” are input to the “RS” connection counter (S3). After the electric vehicle EV1 is being charged, or when the electric vehicle EV1 is not being charged, it is determined whether or not the electric vehicle EV2 is being charged (S4). = RT + 1 "and" RT "connected counters are input with" +1 "(S5). After the electric vehicle EV2 is being charged, or when the electric vehicle EV2 is not being charged, it is determined whether or not the electric vehicle EV3 is being charged (S6). = ST + 1 "and" ST "connected counters are input with" +1 "(S7).

そして、上記電気車両EV3の充電中が入力された後、又は上記電気車両EV3が充電中でない場合、電気車両EV4の充電が必要であるか否かが判断される(S8)。充電中であれば、三相電源の「RS」接続と「RT」接続とのカウンタ数(電流値に相当)が比較され(S9)、同じか「RS」接続が小さい場合には「RS」接続と「ST」接続とのカウンタ数が比較され(S10)、同じか「RS」接続が小さい場合には「A4,D4」が「オン」となり「RS=RS+1」と「RS」接続のカウンタに「+1」が入力される(S11)。上記「RS」接続と「ST」接続とのカウンタ数比較(S10)で「RS」接続が大きい場合には、「B4,C4」が「オン」となり「ST=ST+1」と「ST」接続のカウンタに「+1」が入力される(S12)。   Then, after inputting that the electric vehicle EV3 is being charged or when the electric vehicle EV3 is not being charged, it is determined whether or not the electric vehicle EV4 needs to be charged (S8). If charging is in progress, the number of counters (corresponding to the current value) of the “RS” connection and the “RT” connection of the three-phase power supply is compared (S9), and “RS” if the same or “RS” connection is small. The counter numbers of the connection and the “ST” connection are compared (S10), and if the same or “RS” connection is small, “A4, D4” becomes “ON” and the counters of “RS = RS + 1” and “RS” connection "+1" is input to (S11). When the “RS” connection is large in the counter number comparison between the “RS” connection and the “ST” connection (S10), “B4, C4” becomes “ON” and “ST = ST + 1” and “ST” connection “+1” is input to the counter (S12).

また、上記「RS」接続と「RT」接続とのカウンタ数比較(S9)で「RS」接続が大きい場合には「RT」接続と「ST」接続とのカウンタ数が比較され(S13)、同じか「RT」接続が小さい場合には「A4,C4」が「オン」となり「RT=RT+1」と「RT」接続のカウンタに「+1」が入力される(S14)。   If the “RS” connection is large in the counter number comparison between the “RS” connection and the “RT” connection (S9), the counter numbers of the “RT” connection and the “ST” connection are compared (S13). If the “RT” connection is the same or “A” is small, “A4, C4” is “ON” and “RT = RT + 1” and “+1” are input to the counter of the “RT” connection (S14).

さらに、上記「RT」接続と「ST」接続とのカウンタ数比較(S13)で「RT」接続が大きい場合には「B4,C4」が「オン」となり「ST=ST+1」と「ST」接続のカウンタに「+1」が入力される(S12)。   Furthermore, when the “RT” connection is large in the counter number comparison (S13) between the “RT” connection and the “ST” connection, “B4, C4” becomes “ON” and “ST = ST + 1” and “ST” connection. "+1" is input to the counter (S12).

その後、上記電気車両EV4の充電中が入力された後、又は上記電気車両EV4の充電が必要でない場合、他の電気車両EVnに充電が必要な車両があるか否かが判断される(S15)。この電気車両EV4以降の電気車両EVnにおける判断は、上記電気車両EV4の判断と同様に行われ、三相電源の各相の組み合わせにおけるカウンタ数が比較され、新たな電気車両EVnの接続時にはカウンタ数の小さい組み合わせの相を選択して接続される。これらは上記(S9)〜(S14)と同一であるため、同一符号を付して詳細な説明は省略する。   Thereafter, after inputting that the electric vehicle EV4 is being charged or when the electric vehicle EV4 is not required to be charged, it is determined whether there is a vehicle that needs to be charged in another electric vehicle EVn (S15). . The determination on the electric vehicle EVn after the electric vehicle EV4 is performed in the same manner as the determination on the electric vehicle EV4, the number of counters in each phase combination of the three-phase power supply is compared, and the number of counters when the new electric vehicle EVn is connected. A phase with a small combination of is selected and connected. Since these are the same as the above (S9) to (S14), the same reference numerals are given and the detailed description is omitted.

このように相を選択して開閉器30〜32,33の各接点(A1,B1)〜(A3,B3),(A4,B4,C4,D4)〜(An,Bn,Cn,Dn)を接続/切断する制御は上記充電制御部36によって行われ、各電気車両EV1〜EVnの充電状況を電流検出器CT1〜CTnで検出している電流を電流監視器35で監視し、相バランスが悪くならないように、つまり、各相のアンバランスが少なくなるように上記相選択用開閉器33の接点(A4,B4,C4,D4)〜(An,Bn,Cn,Dn)を切り替えて三相電源の各相を選択的に接続するように制御される。   Thus, the phases are selected and the contacts (A1, B1) to (A3, B3), (A4, B4, C4, D4) to (An, Bn, Cn, Dn) of the switches 30 to 32, 33 are connected. The control for connecting / disconnecting is performed by the charge control unit 36, and the current detected by the current detectors CT1 to CTn is monitored by the current monitor 35 for the charging status of each electric vehicle EV1 to EVn, and the phase balance is poor. The three-phase power source is switched by switching the contacts (A4, B4, C4, D4) to (An, Bn, Cn, Dn) of the phase selection switch 33 so that the unbalance of each phase is reduced. Are controlled so as to selectively connect the respective phases.

従って、機械式駐車設備において採用されている三相電源から電気車両充電用単相電源を取り出しても、充電されている電気車両EV1〜EVnに応じて「三相回路の不平衡」という現象を最小限に抑えるように第一相(R)、第二相(S)、及び第三相(T)のいずれかから選択的に単相電源を取り出すように接続されるようにすることが可能となる。そのため、機械式駐車設備(エレベータ式駐車装置1)に電気車両EV1〜EVnの充電機能を備えさせるために、新たに単相の充電用専用電源を引き込む必要は無く、機械式駐車設備の新設・既設に拘わらず電気車両の充電機能付加のための設備増強・施工費用を安価に抑えることが可能となる。   Therefore, even if the electric vehicle charging single-phase power source is taken out from the three-phase power source adopted in the mechanical parking facility, the phenomenon of “three-phase circuit imbalance” is caused depending on the electric vehicles EV1 to EVn being charged. It is possible to selectively connect the single phase power supply from either the first phase (R), the second phase (S), or the third phase (T) to minimize it. It becomes. Therefore, in order to provide the mechanical parking facility (elevator-type parking device 1) with the charging function for the electric vehicles EV1 to EVn, there is no need to newly draw a single-phase dedicated power source for charging. Regardless of the existing facilities, it is possible to keep down the equipment enhancement and construction costs for adding the charging function of the electric vehicle at a low cost.

また、上記実施の形態において、一般的に機械式駐車設備(エレベータ式駐車装置1)用の電源が駐車装置本体機器の駆動(例えば、エレベータ搬器12の昇降駆動部13等)に供するのに必要な電源容量に合わせて設備されているので、駐車設備の動力用三相電源が駐車設備の動力源(エレベータ搬器12の昇降駆動部13(モータ等の駆動源))に供されているときは、容量不足を回避するために、電気車両EV1〜EVnの充電中であっても全ての開閉器30〜32及び相選択用開閉器33の接点(A1,B1)〜(A3,B3)及び接点(A4,B4,C4,D4)〜(An,Bn,Cn,Dn)を開として充電を中断するようにしてもよい。このようにすれば、駐車設備の電源容量を抑えて電流バランスの良い充電制御を行うことができる。   Moreover, in the said embodiment, it is generally required for the power supply for mechanical parking equipment (elevator type parking apparatus 1) to drive a parking apparatus main body apparatus (for example, the raising / lowering drive part 13 etc. of the elevator transporter 12). When the three-phase power source for the power of the parking facility is provided to the power source of the parking facility (elevating drive unit 13 (drive source such as a motor) of the elevator transporter 12) In order to avoid shortage of capacity, contacts (A1, B1) to (A3, B3) and contacts of all the switches 30 to 32 and the phase selection switch 33 even during charging of the electric vehicles EV1 to EVn Charging may be interrupted by opening (A4, B4, C4, D4) to (An, Bn, Cn, Dn). If it does in this way, the power supply capacity | capacitance of parking equipment can be suppressed and charging control with a sufficient current balance can be performed.

なお、上記実施の形態では、機械式駐車装置として下部90°乗入れ方式のエレベータ式駐車装置1を例に説明したが、充電パレット20を一定時間定位置に格納する方式であればどのような方式の機械式駐車設備であってもよく、例えば、平面往復式、縦横パズル移動式、多段式等、種々の機械式駐車設備に適用することができる。   In the above-described embodiment, the elevator parking apparatus 1 of the lower 90 ° entry system is described as an example of the mechanical parking apparatus. However, any system can be used as long as the charging pallet 20 is stored at a fixed position for a certain period of time. For example, the present invention can be applied to various mechanical parking facilities such as a plane reciprocating type, a vertical and horizontal puzzle moving type, and a multistage type.

また、上記実施の形態のエレベータ式駐車装置1では、電気車両EV用の充電パレット20と、充電付帯器具無しの一般的な標準パレット90とを混載させた例を示したが、全て電気車両EV搭載用の充電パレット20としてもよい。   Moreover, in the elevator type parking apparatus 1 of the said embodiment, although the charging pallet 20 for electric vehicles EV and the general standard pallet 90 without a charging accessory were shown mixedly, all are electric vehicles EV. It is good also as the charging pallet 20 for mounting.

さらに、上記実施の形態では、電気車両EVの4台目以降についてのみ相選択用開閉器33を採用しているが、全ての電気車両EVに相選択用開閉器33を採用して機器の共通化を図ってもよい。   Furthermore, in the above-described embodiment, the phase selection switch 33 is employed only for the fourth and subsequent electric vehicles EV. However, the phase selection switch 33 is employed for all the electric vehicles EV, so that the common device is used. You may plan.

また、上述した実施の形態は一例を示しており、本発明の要旨を損なわない範囲での種々の変更は可能であり、本発明は上述した実施の形態に限定されるものではない。   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.

本発明に係る機械式駐車設備は、三相交流電源で複数台の電気車両に安定して充電したい機械式駐車設備として利用できる。   The mechanical parking facility according to the present invention can be used as a mechanical parking facility that wants to stably charge a plurality of electric vehicles with a three-phase AC power source.
