Description

移動体の電力供給システム，及び，移動体Mobile power supply system and mobile body
　本発明は，主に移動体の電力供給システムに利用される技術に関し，詳しくは，電力供給効率のきわめて優れた，非接触による移動体の電力供給システムと，その移動体に関する。 The present invention relates to a technique mainly used for a power supply system of a mobile body, and more particularly, to a non-contact power supply system of a mobile body with extremely excellent power supply efficiency and the mobile body.
　一般的に，移動体の代表例としての電気自動車は，当該電気自動車に備えられたバッテリに対する充電を行う際に，充電器が備えられている施設において，充電器のケーブルのコネクタを電気自動車に備えられているコネクタに差込んで充電する必要があり，そのための手間が面倒であった。そこで従来技術ではこの点に着目し，自動車を搭載する車両台に交流電力の供給によって所定電力の磁束を発生させる，給電手段としての一次コイルを設け，自動車側には,前記一次コイルからの磁束を受けて所定電力の磁束を発生させる，受電手段としての二次コイルと，当該二次コイルに発生する磁束に対応した電力で蓄電するバッテリを備えさせ，しかも，自動車が所定場所に位置しているときに，前記バッテリの容量が低下していれば，自動的に充電ができるように構成された，非接触による自動車の充電システムが提供されている。
　この自動車の給電システムによると，コイルを使った電磁誘導による非接触の給電方式で構成されており，しかも，例えば，予め決められたパーキングに車を駐車させるだけで充電を開始できることから，給電に係る準備等の必要がなく，その利便性は良い。 In general, an electric vehicle as a representative example of a mobile object is configured such that when charging a battery provided in the electric vehicle, the connector of the charger cable is connected to the electric vehicle in a facility equipped with the charger. It was necessary to insert the connector into the connector and charge it, which was troublesome. Therefore, in the prior art, paying attention to this point, a primary coil is provided as a power supply means for generating a magnetic flux of a predetermined power by supplying AC power to a vehicle base on which the automobile is mounted, and the magnetic flux from the primary coil is provided on the automobile side. And a secondary coil as a power receiving means for generating a magnetic flux of a predetermined power and a battery for storing electricity with electric power corresponding to the magnetic flux generated in the secondary coil, and the automobile is located at a predetermined location. There is provided a non-contact vehicle charging system configured to automatically charge the battery if the capacity of the battery is low.
This automobile power supply system is configured with a non-contact power supply method using electromagnetic induction using a coil, and for example, charging can be started simply by parking the car in a predetermined parking space. There is no need for such preparations, and its convenience is good.

　ところが，従来技術のような非接触による自動車の充電システムでは，一次コイルが備えられるパーキング等の路面と，二次コイルが備えられる自動車の底面との間の間隔が，自動車によって決まってしまい，その空間を隔てた電磁誘導では，二次コイル側に誘起される電力の変換効率は必ずしも良いものでは無いといった問題があった。更に加えて，自動車をパーキングに駐車したときの停め方によっては，一次コイルと二次コイルとが正対せず，一次コイルと二次コイルの位置が，最も効率が良くなる状態からズレたままで給電が始まる場合があり，その点においても電力の変換効率を適正に保つことができない場合が考えられる。そのため，従来技術のような非接触による自動車の給電システムでは，充電時間が長時間必要となるといった問題があった。また，これに対応するために，一次コイル及び二次コイルを大きくしたり，パワーアップしたりする方法も考えられるが，装置が大きくなることによって，車に搭載し難くなったり，コストがアップしたりするといった問題があった。 However, in a non-contact automobile charging system such as the prior art, the distance between the road surface of the parking etc. provided with the primary coil and the automobile bottom provided with the secondary coil is determined by the automobile. In the electromagnetic induction across the space, there is a problem that the conversion efficiency of the power induced on the secondary coil side is not always good. In addition, depending on how the vehicle is parked, the primary coil and the secondary coil may not face each other, and the primary and secondary coils may be displaced from the most efficient state. In some cases, power supply may start, and even in this respect, the power conversion efficiency may not be maintained properly. For this reason, the non-contact automobile power supply system as in the prior art has a problem that a long charging time is required. In order to cope with this, a method of enlarging the primary coil and the secondary coil or increasing the power can be considered. However, as the device becomes larger, it becomes difficult to install in the vehicle and the cost increases. There was a problem such as.

The other purpose is a non-contact type movement that can automatically supply power with optimum efficiency automatically even if the vehicle is stopped roughly and the power supply means (primary coil) and the power reception means (secondary coil) do not face each other. It is to provide a body power supply system.

　本発明に係る自動車の電力供給システムは，電力受電装置２０を備えた自動車２と，道路側に備えられた電力給電装置３０から構成されており，前記自動車２を，図１によく示されるような，例えば，当該電力給電装置３０を備えた前記駐車スペース３に停めることによって，電力の供給が開始されるように構成されている。 The power supply system for a vehicle according to the present invention includes a vehicle 2 provided with a power receiving device 20 and a power supply device 30 provided on the road side. The vehicle 2 is shown well in FIG. For example, power supply is started by stopping in the parking space 3 provided with the power supply device 30.
　このように構成された本発明の第１実施形態は，前記電力受電装置２０と前記電力給電装置３０の位置関係に特徴を有しており，詳しくは，前記電力給電装置３０の構成要素の内，特に，前記自動車２に備えられた電力受電装置２０の受電手段２１に対し，非接触で電力を供給するための給電手段３１の構成に基づくものである。 The first embodiment of the present invention configured as described above is characterized in the positional relationship between the power receiving device 20 and the power feeding device 30, and more specifically, among the components of the power feeding device 30. In particular, this is based on the configuration of the power feeding means 31 for supplying power to the power receiving means 21 of the power receiving device 20 provided in the automobile 2 in a contactless manner.
　具体的には，本発明の第１実施形態における前記給電手段３１は，路面１とは固定されず，独立した状態で形成されていると共に，更に，前記給電手段３１には，後に詳述する可動手段３６を備えさせることによって，前記給電手段３１の配設位置を自在に変えることができるように構成されているのであるが，本発明の第１実施形態では，図１に示されたような，給電手段３１が，その上面を駐車スペース３の路面１と略平坦となるように収納された一般的な状態と，更に加えて，図１には示されていない状態である，給電手段３１が前記可動手段３６によって路面１と略平行状態を保ったまま上方に持ち上げられ，前記受電手段２１との間が所定の間隔となるように配設された状態の，２様の配設状態を有するように構成されているのである。 Specifically, the power feeding means 31 in the first embodiment of the present invention is not fixed to the road surface 1 and is formed in an independent state. Further, the power feeding means 31 will be described in detail later. By providing the movable means 36, the arrangement position of the power supply means 31 can be freely changed. In the first embodiment of the present invention, as shown in FIG. The power supply means 31 is in a general state in which the upper surface thereof is housed so that the upper surface thereof is substantially flat with the road surface 1 of the parking space 3, and in addition, the power supply means is in a state not shown in FIG. Two disposition states in which 31 is lifted upward by the movable means 36 while maintaining a substantially parallel state with the road surface 1 and disposed at a predetermined distance from the power receiving means 21. It is configured to have A.
　一方，自動車２側に備えられた設備である前記電力受電装置２０は，少なくとも，非接触で電力の供給を受けるための受電手段２１が，自動車２を所定の位置に停めたとき，つまり，前記駐車スペース３のような，予め定められた場所（即ち，電力給電装置３０を備えた場所）に車を停めたときに，前記給電手段３１と対向する，図では示されていない自動車２の底面に位置するように備えられている。 On the other hand, the power receiving device 20 which is a facility provided on the side of the automobile 2 is at least when the power receiving means 21 for receiving power supply in a non-contact manner stops the automobile 2 at a predetermined position, that is, The bottom surface of the automobile 2 not shown in the figure, facing the power supply means 31 when the vehicle is parked at a predetermined location (that is, a location having the power supply device 30) such as the parking space 3. It is equipped to be located in.
　このように構成された本発明の第１実施形態を使った，駐車場における自動車の電力供給システムを簡単に説明する。電力受電装置２０を備えた自動車２を，電力給電装置３０を備えた，例えば駐車スペース３のような所定の場所に駐車させ，前記給電手段３１と前記受電手段２１が対向配置すると，前記電力受電装置２０と前記電力給電装置３０の間で「所定の手続」が行われ，充電が可能であるかどうかが判定される。ここで，充電が可能であると判定されたならば，前記給電手段３１が前記受電手段２１に向かって，所定の間隔となるまで上昇し，その配置が完了したなら，前記所定の間隔を保った状態で，前記給電手段３１と前記受電手段２１との間で電磁誘導を起こすことによって，前記電力受電装置２０に備えられた，図には示されていない蓄電手段に対して，前記受電手段２１で受電した電力を，非常に効率よく蓄電することができるように構成されている。 The electric power supply system for a car in a parking lot using the first embodiment of the present invention configured as described above will be briefly described. When the automobile 2 provided with the power receiving device 20 is parked in a predetermined place such as the parking space 3 provided with the power feeding device 30, and the power feeding means 31 and the power receiving means 21 are arranged to face each other, the power receiving power is received. A “predetermined procedure” is performed between the device 20 and the power supply device 30 to determine whether charging is possible. Here, if it is determined that charging is possible, the power feeding means 31 rises toward the power receiving means 21 until a predetermined interval is reached, and if the arrangement is completed, the predetermined interval is maintained. In this state, by causing electromagnetic induction between the power feeding means 31 and the power receiving means 21, the power receiving means is provided for the power storage means (not shown) provided in the power receiving device 20. The power received at 21 can be stored very efficiently.
　つまり，給電手段３１の上面を駐車スペース３の路面１と略平坦となるように配設した一般的な状態は，言い換えれば「給電前の状態」であり，給電手段３１が路面１と略平坦な状態を保った状態から更に上昇し，前記受電手段２１との間を所定の間隔となるように配設した状態は，言い換えれば「給電時における状態」であるように，本発明は，「給電前の状態」と「給電時における状態」で，それぞれ，給電手段３１と受電手段２１との間隔を替えるように構成し，特に給電時には，給電手段３１と受電手段２１との離隔距離を一層狭くして電磁結合が密になるように構成することによって，システムの給電効率を極めてよくすることを主たる目的としているのである。 That is, the general state in which the upper surface of the power supply means 31 is disposed so as to be substantially flat with the road surface 1 of the parking space 3 is, in other words, the “state before power supply”, and the power supply means 31 is substantially flat with the road surface 1. The present invention is further described as “a state at the time of power feeding”, in which the state of further rising from the state in which the state is maintained and being arranged at a predetermined interval from the power receiving means 21 is “a state during power feeding”. The power supply unit 31 and the power receiving unit 21 are configured so that the distance between the power supply unit 31 and the power reception unit 21 is changed between the “state before power supply” and the “state during power supply”, respectively. The main purpose is to improve the power supply efficiency of the system by narrowing it so that the electromagnetic coupling becomes dense.

In FIG. 4, part (a) is a flowchart for explaining the processing of the power supply side system control means 35a, and part (b) is the driving of the primary coil 31a performed in accordance with the processing of the power supply side system control means 35a. The procedure of is shown.
　先ず，図４の（ａ）部分を用いて前記給電側システム制御手段３５ａの処理を説明する。本発明の実施形態では，前記給電側システム制御手段３５ａが，前記充電希望信号を受けたとき（Ｓ１０　Ｙｅｓの場合）は，前記給電側システム制御手段３５ａから前記可動手段３６に対し，可動手段３６を起動するための前記制御信号を出力（「ＯＮ」信号）することによって（Ｓ１２），給電手段３１は，図３によく示されるように，路面１より上昇して，給電時における状態である「第２の位置」に配設される。更に，前記給電側システム制御手段３５ａは，例えば，可動手段３６（若しくは給電手段３１）の配設状態を監視し，前記給電手段３１が「第２の位置」に配設されたことによって，前記可動手段３６から「第２の配置」のリミット信号を取得したなら（Ｓ１４　Ｙｅｓの場合），前記開閉器３３に対して「閉」の駆動信号を出力（「ＯＮ」信号）することによって（Ｓ１６），給電手段３１から受電手段２１に電力の供給が開始されるのである。そして，前記給電側システム制御手段３５ａは「閉」の駆動信号を出力したなら次のステップである，主バッテリ２３の電力容量の判定に移行する（Ｓ１８）。また，前記給電手段３１が「第２の位置」に配設されていない場合は（Ｓ１４　Ｎｏの場合），ステップ（Ｓ１２）に戻って処理を繰り返す。 First, the processing of the power supply side system control means 35a will be described using the part (a) of FIG. In the embodiment of the present invention, when the power supply side system control means 35a receives the charge request signal (Yes in S10), the power supply side system control means 35a controls the movable means 36 with respect to the movable means 36. By outputting the control signal for starting up ("ON" signal) (S12), the power feeding means 31 rises above the road surface 1 and is in a state during power feeding, as well shown in FIG. Arranged at the “second position”. Further, the power supply side system control means 35a monitors, for example, the disposition state of the movable means 36 (or the power supply means 31), and the power supply means 31 is disposed at the “second position”. When the limit signal of “second arrangement” is acquired from the movable means 36 (in the case of S14, Yes), a “closed” drive signal is output (“ON” signal) to the switch 33 (S16). ), Power supply from the power supply means 31 to the power reception means 21 is started. Then, if the power supply side system control means 35a outputs a drive signal of “closed”, the process proceeds to the determination of the power capacity of the main battery 23, which is the next step (S18). If the power supply means 31 is not disposed at the “second position” (No in S14), the process returns to Step (S12) and is repeated.
　尚，この「閉」の駆動信号を出力するタイミングは，可動手段３６若しくは給電手段３１の配設状態を監視してリミット信号を判定する方法に替わって，所定の時間（つまり，給電手段３１が上昇する間）だけ遅延させて出力するように構成しても良い。 It should be noted that the timing at which this “closed” drive signal is output is a predetermined time (that is, the power supply means 31 is not connected to the method of determining the limit signal by monitoring the arrangement of the movable means 36 or the power supply means 31). It may be configured to output with a delay only during the rise.
　一方，前記給電側システム制御手段３５ａが，前記充電希望信号を受けていないとき（Ｓ１０　Ｎｏの場合）は，前記給電側システム制御手段３５ａが，前記可動手段３６に対しシステムを待機状態にするための前記制御信号を出力（「ＯＦＦ」信号）する（Ｓ２０）ことによって，給電手段３１は，図２によく示されるように，給電手段３１の上面を路面１とフラットな状態となるように収納した，給電前の位置である「第１の位置」に配設され，更に，開閉器３３に対し「開」の駆動信号を出力（「ＯＦＦ」信号）する（Ｓ２２）ことによって，給電手段３１から受電手段２１に対する電力の供給は行われないのである。 On the other hand, when the power supply side system control means 35a does not receive the charge request signal (in the case of S10 No), the power supply side system control means 35a places the system in a standby state with respect to the movable means 36. 2 is output (“OFF” signal) (S20), the power feeding means 31 stores the upper surface of the power feeding means 31 so as to be flat with the road surface 1 as well shown in FIG. The power supply means 31 is arranged at the “first position” which is the position before power supply, and further outputs an “open” drive signal (“OFF” signal) to the switch 33 (S22). Thus, no power is supplied to the power receiving means 21.
　加えて，前記給電側システム制御手段３５ａは，主バッテリ２３の電力容量を監視し（Ｓ１８），その状態に基づいて前記受電側システム制御手段３５ｂから送られてくる信号に応じて，自動車２を駐車スペースに停めたときに，主バッテリ２３の電力容量が所定値より低ければ充電を開始し（Ｓ１８　Ｎｏの場合），電力容量が所定値以上あるとき，または，充電中に所定値になったときに（Ｓ１８　Ｙｅｓの場合），前記受電側システム制御手段３５ｂから送られていくる，満充電情報である充電完了信号に応じて，可動手段３６の制御と一次コイル３１ａの駆動をやめ（Ｓ２０，Ｓ２２），給電手段３１はデフォルトの「第１の配置」に収納状態に戻される。 In addition, the power supply side system control means 35a monitors the power capacity of the main battery 23 (S18), and determines the vehicle 2 according to the signal sent from the power reception side system control means 35b based on the state. When parked in the parking space, if the power capacity of the main battery 23 is lower than the predetermined value, charging starts (in the case of S18 No), and when the power capacity is equal to or higher than the predetermined value, or reaches the predetermined value during charging Sometimes (in the case of S18 Yes), the control of the movable means 36 and the driving of the primary coil 31a are stopped according to the charge completion signal which is the full charge information sent from the power receiving side system control means 35b (S20, S22), the power feeding means 31 is returned to the default “first arrangement”.
　次に，図４の（ｂ）部分において示される一次コイル３１ａの駆動の手順を説明する。この手順は，上記給電側システム制御手段３５ａの処理とリアルタイムで行われる。一次コイル３１ａが「第２の配置」になったときに，前記給電側システム制御手段３５ａから出力される駆動信号をうけて（Ｓ２６），開閉器３３が導通状態となることによって（Ｓ２８），駆動回路３２に交流電力が供給され（Ｓ３０），一次コイル３１ａと二次コイル２１ａの間で給電が始まるように構成されている（Ｓ３２）。 Next, the driving procedure of the primary coil 31a shown in the part (b) of FIG. 4 will be described. This procedure is performed in real time with the processing of the power supply side system control means 35a. When the primary coil 31a is in the “second arrangement”, the drive signal output from the power supply side system control means 35a is received (S26), and the switch 33 is turned on (S28). AC power is supplied to the drive circuit 32 (S30), and power feeding is started between the primary coil 31a and the secondary coil 21a (S32).
　尚，前記本発明の第１実施形態では，受電希望信号を受けたなら，前記給電側システム制御手段３５ａから出力される制御信号によって可動手段３６を動かして，給電手段３１の配設位置を替えた後に，前記給電側システム制御手段３５ａから出力される駆動信号でもって開閉器３４を閉じて，給電手段３１から受電手段２１への給電を開始する構成となっているのであるが，給電手段３１を動かすタイミングと給電を開始するタイミングをほぼ同時に行うように構成してもよい。 In the first embodiment of the present invention, when the power reception request signal is received, the movable means 36 is moved by the control signal output from the power supply side system control means 35a to change the arrangement position of the power supply means 31. After that, the switch 34 is closed by the drive signal output from the power supply side system control means 35a, and the power supply from the power supply means 31 to the power reception means 21 is started. You may comprise so that the timing which moves may be performed substantially simultaneously with the timing which starts electric power feeding.
　また，充電が完了した場合や，充電の途中で充電を止める場合における，システムの終了手順は，先ず，給電手段３１を「第１の配置」に収容する手順を行ってから給電の停止の手順を行うようにしても良いし，給電手段３１を「第１の配置」に収容する手順と，給電の停止の手順を同時に行っても良い。 In addition, when the charging is completed or when the charging is stopped in the middle of charging, the system ending procedure is to first stop the power supply after performing the procedure of accommodating the power supply means 31 in the “first arrangement”. Alternatively, the procedure for accommodating the power feeding means 31 in the “first arrangement” and the procedure for stopping the power feeding may be performed simultaneously.
　更に，主バッテリ２３が満充電でない状態で充電を止めるような場合，給電手段３１を「第１の配置」に収容するまで，前記モータ２５の制御ができないような構成にしておくことはいうまでも無い。具体的には，給電側システム制御手段３５ａは，前記給電手段３１が「第１の位置」に収納されていることを示す，「第１の配置」のリミット信号を常時監視することによって，給電側システム制御手段３５ａが，当該「第１の配置」のリミット信号を検出しない限り，前記モータ２５の制御ができないように構成すればよい。 Further, in the case where charging is stopped when the main battery 23 is not fully charged, the motor 25 cannot be controlled until the power feeding means 31 is accommodated in the “first arrangement”. There is no. Specifically, the power supply side system control unit 35a constantly monitors a limit signal of “first arrangement” indicating that the power supply unit 31 is housed in the “first position”. It may be configured such that the motor 25 cannot be controlled unless the side system control means 35a detects the limit signal of the “first arrangement”.
　このように，本発明の第１実施形態によれば，前記電力受電装置２０を備えた自動車２を，前記電力給電装置３０を備えた所定の駐車スペース３に停め，少なくともパーキングブレーキを掛け，自動車２を確実に停車状態にすることによって，前記電力受電装置２０側から前記電力給電装置３０側に対して充電希望信号が送出され，電力給電装置３０に備えた給電側システム制御手段３５ａがその充電希望信号を受ける，と言った「所定の手続」を経ることで，前記電力給電装置３０側では，給電手段３１が，給電前の状態である前記「第１の配置」の配設状態から，受電手段２１に向かって上昇して，給電手段３１と受電手段２１の離隔距離を，相互に所定の間隔を保って近接した，給電における状態である前記「第２の配置」の配設状態になると共に，駆動回路３２に開閉器３３を介して交流電力を供給することによって，給電手段３１を構成する一次コイル３１ａが駆動され，受電手段２１を構成する二次コイル２１ａとの間で電磁誘導による給電が始まるような構成にした。
　これによって，前記電力受電装置２０を搭載した自動車２が前記駐車スペース３に駐車したあとは，一次コイル３１ａが上昇することによって，二次コイル２１ａの電磁結合が密になり，二次コイル２１ａ側に効率よく電力を誘起でき，主バッテリ２３に対する充電時間等の短縮が図れる。また，一次コイル３１ａと二次コイル２１ａの変換効率が良くなるので，コイルの大きさを小さくでき，自動車２への搭載や，駐車スペース３への設置を，より簡単に行うことができるようになる。 As described above, according to the first embodiment of the present invention, the automobile 2 provided with the power receiving device 20 is stopped in the predetermined parking space 3 provided with the power feeding device 30, and at least a parking brake is applied. 2 is reliably stopped, a charging request signal is sent from the power receiving device 20 side to the power feeding device 30 side, and the power feeding side system control means 35a provided in the power feeding device 30 performs the charging. By passing through a “predetermined procedure” to receive a desired signal, the power feeding unit 31 on the side of the power feeding device 30 is changed from the arrangement state of the “first arrangement” which is a state before feeding. Arrangement state of the “second arrangement”, which is a state in which the power feeding means 21 rises toward the power receiving means 21 and the separation distance between the power feeding means 31 and the power receiving means 21 is close to each other while maintaining a predetermined distance. In addition, by supplying AC power to the drive circuit 32 via the switch 33, the primary coil 31a constituting the power feeding means 31 is driven, and electromagnetic induction is performed between the secondary coil 21a constituting the power receiving means 21. The configuration is such that the power supply by is started.
As a result, after the automobile 2 equipped with the power receiving device 20 is parked in the parking space 3, the primary coil 31a rises, so that the electromagnetic coupling of the secondary coil 21a becomes dense, and the secondary coil 21a side Thus, it is possible to induce electric power efficiently and shorten the charging time for the main battery 23. Further, since the conversion efficiency of the primary coil 31a and the secondary coil 21a is improved, the size of the coil can be reduced, so that it can be mounted on the automobile 2 or installed in the parking space 3 more easily. Become.
　また，前記電力受電装置２０を搭載した自動車２が前記電力給電装置３０を備えた駐車スペース３に駐車しても，前記充電希望信号は，少なくともパーキングブレーキを掛けて，車を確実に停車させないと出力されない構成であり，しかも，電力給電装置３０側が前記電力受電装置２０側からの充電希望信号を受信する「所定の手続」をしない限り，給電手段３１を駆動しない構成であるので，電力供給システムを安全に動作させることができるし省エネルギーとすることができる。 In addition, even if the automobile 2 equipped with the power receiving device 20 parks in the parking space 3 provided with the power feeding device 30, the charge request signal must be applied at least with a parking brake to stop the vehicle securely. Since the power supply device 30 does not drive the power supply means 31 unless the power supply device 30 performs a “predetermined procedure” for receiving a charge request signal from the power power reception device 20, the power supply system Can be operated safely and energy can be saved.
　加えて，前記電力受電装置２０を搭載した自動車２であっても，前記電力受電装置２０を搭載していない一般の自動車であっても，前記電力給電装置３０を備えた駐車スペース３に車を駐車しようとするときは，前記給電手段３１と前記受電手段２１は「第１の配置」にあるので，車の駐車に際して何ら邪魔になることはないし，当該自動車２が停められていない駐車スペース３において，歩行者等に危険や危害を及ぼすことがない。 In addition, whether the vehicle 2 is equipped with the power receiving device 20 or a general vehicle not equipped with the power receiving device 20, the vehicle is placed in the parking space 3 provided with the power feeding device 30. When parking, the power feeding means 31 and the power receiving means 21 are in the “first arrangement”, so that there is no obstacle in parking the car, and the parking space 3 where the automobile 2 is not parked. However, there is no danger or harm to pedestrians.
　次に，本発明の第２実施形態について図５を基に説明する。尚，以下の説明において，特に明示しない限り，前記第１実施形態と同じ構成を有するものは同一符号を付与し，詳細な説明は省略する。 Next, a second embodiment of the present invention will be described with reference to FIG. In the following description, unless otherwise specified, those having the same configuration as in the first embodiment are given the same reference numerals, and detailed description thereof is omitted.
　図５に示される第２実施形態と，すでに説明した前記第１実施形態との違いは，可動手段３６の取り付け位置の違いである。図５に示されるように，この異なる実施例では，可動手段３６は，自動車２側に搭載された電力受電装置２０側の受電手段２１に備えられている。 The difference between the second embodiment shown in FIG. 5 and the first embodiment described above is the difference in the mounting position of the movable means 36. As shown in FIG. 5, in this different embodiment, the movable means 36 is provided in the power receiving means 21 on the side of the power receiving apparatus 20 mounted on the side of the automobile 2.
　つまり，この実施例では，一次コイル３１ａが路面１側に固定されるようにして給電手段３１が構成されており，自動車２に備えられた受電手段２１は，二次コイル２１ａが，車体とは別体に備えられた支持部材である基台２１ｂと一体となるように構成されていると共に，自動車２側に可動手段３６を備えたことによって，受電手段２１の配設位置を変えることができるように構成されているのである。 That is, in this embodiment, the power feeding means 31 is configured such that the primary coil 31a is fixed to the road surface 1, and the power receiving means 21 provided in the automobile 2 is configured such that the secondary coil 21a is different from the vehicle body. It is configured to be integrated with a base 21b which is a support member provided separately, and the movable unit 36 is provided on the side of the automobile 2 so that the arrangement position of the power receiving unit 21 can be changed. It is configured as follows.
　このため，電力受電装置２０に備えた受電側システム制御手段３５ｂは，第１実施形態のように主バッテリ２３の電力容量を監視するばかりでなく，前記可動手段３６からのリミット信号の監視や，前記可動手段３６に対する制御信号の出力を行うように構成されている。 For this reason, the power receiving side system control means 35b provided in the power receiving apparatus 20 not only monitors the power capacity of the main battery 23 as in the first embodiment, but also monitors the limit signal from the movable means 36, A control signal is output to the movable means 36.
　具体的には，起動判定手段２６においてパーキングブレーキが「ＯＮ」であると判定されたなら，前記受電側送信手段２７に対して，それに応じた信号を出力する。そして，受電側送信手段２７から電力給電装置３０側に向かって充電希望信号が送信される。電力給電装置３０では，給電側システム制御手段３５ａがその充電希望信号を受けるばかりでなく，更には，当該充電希望信号を受けたことを示す信号であって，電力受電装置２０に備えた受電側システム制御手段３５ｂに向けた，可動手段３６の制御を許可するための応答信号を出力する。そのため，電力給電装置３０には，当該応答信号を，前記電力受電装置２０側に送信する，通信部３７ａと送信アンテナ３７ｂとからなる給電側送信手段３７が備えられており，電力受電装置２０に対して前記応答信号を送信する。 More specifically, if the activation determination means 26 determines that the parking brake is “ON”, it outputs a corresponding signal to the power receiving side transmission means 27. Then, a charge request signal is transmitted from the power receiving side transmitting means 27 toward the power feeding device 30 side. In the power supply device 30, not only the power supply side system control means 35 a receives the charge request signal, but also a signal indicating that the charge request signal has been received. A response signal for permitting control of the movable means 36 toward the system control means 35b is output. Therefore, the power feeding device 30 is provided with power feeding side transmission means 37 including a communication unit 37a and a transmission antenna 37b for transmitting the response signal to the power receiving device 20 side. In response to this, the response signal is transmitted.
　電力受電手段２０には，電力給電装置３０側の給電側送信手段３７からの前記応答信号を受信する，受信アンテナ２８ｂと通信部２８ａからなる受電側受信手段２８が備えられており，前記応答信号は，該受電側受信手段２８を介して電力受電装置２０に備えた受電側システム制御手段３５ｂに出力される。 The power receiving unit 20 includes a power receiving side receiving unit 28 including a receiving antenna 28b and a communication unit 28a for receiving the response signal from the power feeding side transmitting unit 37 on the power feeding device 30 side. Is output to the power receiving side system control means 35b provided in the power receiving device 20 via the power receiving side receiving means 28.
　前記受電側システム制御手段３５ｂでは，前記応答信号を受けて，可動手段３６に対し制御信号を出力し，そして，前記受電手段２１は，前記制御信号を受けた前記可動手段３６によって，一次コイル３１ａとの間隔を狭めるように，前記「第２の配置」まで下降するのである。 The power receiving side system control means 35b receives the response signal and outputs a control signal to the movable means 36, and the power receiving means 21 receives the control signal and the primary coil 31a by the movable means 36. The distance is lowered to the “second arrangement” so as to narrow the interval.
　更に加えて，前記受電側システム制御手段３５ｂは，前記可動手段３６が，前記受電手段２１を前記「第２の配置」に配設し終わったこと示す，「第２の配置」のリミット信号を検出すると共に，その結果を駆動許可信号として，前記受電側送信手段２７を介して，電力給電装置３０に備えた給電側システム制御手段３５ａに向けて送出する。 In addition, the power receiving side system control means 35b provides a limit signal of “second arrangement” indicating that the movable means 36 has arranged the power receiving means 21 in the “second arrangement”. At the same time, the result is sent as a drive permission signal to the power supply side system control means 35 a provided in the power supply apparatus 30 via the power reception side transmission means 27.
　給電側システム制御手段３５ａでは，当該駆動許可信号を受けて，開閉器３３に対して「閉」の駆動信号を出力する。そして，開閉器３３は，この「閉」の駆動信号に基づいて導通状態となり，駆動回路３２に交流電力が供給されることによって一次コイル３１ａが駆動されるのである。 In response to the drive permission signal, the power supply side system control means 35 a outputs a “closed” drive signal to the switch 33. The switch 33 becomes conductive based on this “closed” drive signal, and the primary coil 31 a is driven by supplying AC power to the drive circuit 32.
　つまり，本発明の第２実施形態では，自動車２側の底面に備えた受電手段２１が下降する構成であるが，上述したように，前記電力受電装置２０と前記電力給電装置３０との間で，充電希望信号の受信，及び，それに対する応答信号の受信と言った「所定の手続」が得られない限り，受電手段２１が下降することがないので，自動車側に可動式の受電手段２１を備えても，自動車道等の安全運行に支障は生じないのである。更に加えて，前記「所定の手続」が完了し，受電手段２１が「第２の配置」にならないかぎり，前記電力受電装置２０から前記電力給電装置３０に対して，前記駆動許可信号が送出されず，一次コイル３１ａが駆動されないので，省エネルギーが実現できるのである。 That is, in the second embodiment of the present invention, the power receiving means 21 provided on the bottom surface on the automobile 2 side is lowered, but as described above, between the power receiving device 20 and the power feeding device 30. Unless the “predetermined procedure” such as reception of the charging request signal and reception of the response signal is obtained, the power receiving means 21 will not be lowered, so that the movable power receiving means 21 is provided on the vehicle side. Even if it is prepared, it will not interfere with the safe operation of the expressway. In addition, as long as the “predetermined procedure” is completed and the power receiving means 21 is not in the “second arrangement”, the drive permission signal is sent from the power receiving device 20 to the power feeding device 30. Therefore, the primary coil 31a is not driven, so that energy saving can be realized.
　このように，本発明の第２実施形態によれば，前記電力受電装置２０を備えた自動車２を，前記電力給電装置３０を備えた所定の駐車スペース３に停め，少なくともパーキングブレーキを掛け，自動車２を確実に停車状態にしたときに，前記電力受電装置２０側から前記電力給電装置３０側に対して充電希望信号が送出され，そして，その充電希望信号を電力給電装置３０が受け，更に，電力給電装置３０から前記電力受電装置２０側に対して応答信号が送出され，その応答信号を前記電力受電装置２０が受ける，と言った「所定の手続」を経ることで，先ず，受電手段２１が給電手段３１の一次コイル３１ａに向かって下降して，一次コイル３１ａと二次コイル２１ａの離隔距離を，前記「第２の配置」の配設状態とすると共に，その配設を待って，開閉器３３を介して駆動回路３２に交流電力の供給が行われることで一次コイル３１ａが駆動され，二次コイル２１ａとの間で電磁誘導による給電が始まる。
　このように構成したことによって，前記電力受電装置２０を搭載した自動車２が前記駐車スペース３に駐車したあとは，二次コイル２１ａが下降することによって，一次コイル３１ａとの電磁結合が密になり，二次コイル２１ａ側に効率よく電力を誘起でき，主バッテリ２３に対する充電時間等の短縮が図れる。また，一次コイル３１ａと二次コイル２１ａの変換効率が良くなるので，コイルの大きさを小さくでき，自動車２への搭載や，駐車スペース３への設置を，より簡単に行うことができるようになる。 As described above, according to the second embodiment of the present invention, the automobile 2 provided with the power receiving device 20 is stopped in the predetermined parking space 3 provided with the power feeding device 30, and at least a parking brake is applied. 2 is reliably stopped, a charge request signal is sent from the power receiving device 20 side to the power supply device 30 side, and the power supply device 30 receives the charge request signal, A power receiving device 21 first receives a response signal from the power feeding device 30 to the power receiving device 20 and receives the response signal by the power receiving device 20. Is lowered toward the primary coil 31a of the power feeding means 31, and the separation distance between the primary coil 31a and the secondary coil 21a is set to the arrangement state of the “second arrangement” and the arrangement thereof. Wait, the primary coil 31a by supply of AC power to the drive circuit 32 via the switch 33 is performed is driven, power supply by electromagnetic induction begins with the secondary coil 21a.
With this configuration, after the automobile 2 on which the power receiving device 20 is mounted is parked in the parking space 3, the secondary coil 21a is lowered so that the electromagnetic coupling with the primary coil 31a becomes dense. Thus, electric power can be efficiently induced on the secondary coil 21a side, and the charging time for the main battery 23 can be shortened. Further, since the conversion efficiency of the primary coil 31a and the secondary coil 21a is improved, the size of the coil can be reduced, so that it can be mounted on the automobile 2 or installed in the parking space 3 more easily. Become.
　また，前記電力受電装置２０を搭載した自動車２が前記電力給電装置３０を備えた駐車スペース３に駐車しても，前記充電希望信号は，少なくともパーキングブレーキを掛けて，車を確実に停車させないと出力されない構成であり，しかも，前記電力受電装置２０側からの充電希望信号を受信し，電力給電装置３０側が応答信号を返す，前記「所定の手続」をしない限り，給電手段３１を駆動しない構成であるので，電力供給システムを安全に動作させることができるし省エネルギーとすることができる。 In addition, even if the automobile 2 equipped with the power receiving device 20 parks in the parking space 3 provided with the power feeding device 30, the charge request signal must be applied at least with a parking brake to stop the vehicle securely. A configuration in which the power supply unit 31 is not driven unless the “predetermined procedure” is performed, in which the charging request signal is received from the power receiving device 20 side and the response signal is returned from the power feeding device 30 side. Therefore, the power supply system can be operated safely and energy can be saved.
　また，自動車２が前記電力給電装置３０を備えた駐車スペース３に駐車し，しかも，前記電力受電装置２０と電力給電装置３０との間で，前記「所定の手続」がなされない限り，前記受電手段３１が下降しないので，当該自動車２の一般道路等における安全運行にまったく支障が生じることがない。 Further, unless the automobile 2 is parked in the parking space 3 having the power feeding device 30 and the “predetermined procedure” is not performed between the power receiving device 20 and the power feeding device 30, the power receiving Since the means 31 does not descend, there will be no hindrance to safe operation of the automobile 2 on a general road or the like.
　加えて，上記第１実施形態と同様に，前記電力受電装置２０を搭載した自動車２であっても，前記電力受電装置２０を搭載していない一般の自動車であっても，前記電力給電装置３０を備えた駐車スペース３に車を駐車しようとするときは，前記給電手段３１が路面に固定されているので，車の駐車に際して邪魔になることはないし，当該自動車２が停められていない駐車スペース３において，歩行者等に危険や危害を及ぼすことがない。 In addition, similar to the first embodiment, even if the vehicle 2 is equipped with the power receiving device 20 or is a general vehicle not equipped with the power receiving device 20, the power feeding device 30 is used. When the vehicle is to be parked in the parking space 3 provided with the above, since the power feeding means 31 is fixed to the road surface, it does not interfere with the parking of the car and the parking space where the automobile 2 is not parked In No. 3, there is no danger or harm to pedestrians.
　次に本発明の第３実施形態として図６から図８を参照して説明する。本発明の第１実施形態と第３実施形態の主たる違いは，可動手段３６の動きの違いにある。本発明の第１実施形態における可動手段３６は，一次次コイル３１ａと二次コイル２１ａの離隔距離を替えるように基台を動かせばよいため，可動手段３６は，一方向（本発明では上下であり，以下の説明ではＺ軸と記載する。）に伸縮するものであればよいが，本発明の第３実施形態における可動手段３６は，Ｚ軸方向の伸縮に加え，給電手段３１を，Ｚ軸方向に直交する方向（即ち，給電手段３１がなす平面に平行な方向であり，以下の説明ではＸ軸，Ｙ軸で規定される座標で記載する。）へ可動できるように構成されている。つまり，本発明の第３実施形態では，一次コイル３１ａと二次コイル２１ａの離隔距離を，基準点である「第１の配置」の配設状態から，Ｚ軸方向に移動した「第２の配置」の配設状態に替えることができるばかりでなく，更に，一次コイル３１ａと二次コイル２１ａの間隔を保った状態のままで，給電手段３１がなす平面に平行な方向の相対位置を，「第２の配置」からＸ軸，Ｙ軸方向における所定の範囲内の，任意の座標である「第３の配置」の配設状態の何れかに替えることができるようになっているのである。 Next, a third embodiment of the present invention will be described with reference to FIGS. The main difference between the first embodiment and the third embodiment of the present invention is the difference in the movement of the movable means 36. Since the movable means 36 in the first embodiment of the present invention only has to move the base so as to change the separation distance between the primary coil 31a and the secondary coil 21a, the movable means 36 can move in one direction (in the present invention, up and down). Yes, in the following description, it will be described as Z-axis). However, the movable means 36 in the third embodiment of the present invention is not limited to expansion and contraction in the Z-axis direction, and the power feeding means 31 is It is configured to be movable in a direction orthogonal to the axial direction (that is, a direction parallel to the plane formed by the power feeding means 31 and described in the following description with coordinates defined by the X axis and the Y axis). . That is, in the third embodiment of the present invention, the separation distance between the primary coil 31a and the secondary coil 21a is changed from the arrangement state of the “first arrangement” as the reference point to the “second axis” moved in the Z-axis direction. In addition to being able to change to the arrangement state of “arrangement”, the relative position in the direction parallel to the plane formed by the power feeding means 31 is maintained while maintaining the distance between the primary coil 31a and the secondary coil 21a. It is possible to change from “second arrangement” to any arrangement state of “third arrangement” which is an arbitrary coordinate within a predetermined range in the X-axis and Y-axis directions. .
　図６を用いて本発明の第３実施形態について詳しく説明する。尚，図６には給電手段３１が給電状態にあって，しかも，給電手段３１が図の左右に位置を替える様子が示されている。 The third embodiment of the present invention will be described in detail with reference to FIG. FIG. 6 shows a state in which the power feeding means 31 is in a power feeding state and the position of the power feeding means 31 is changed to the left and right in the drawing.
　この実施形態における電力給電装置３０も，自動車２に備えた電力受電装置２０側からの充電希望信号に応じて，当該装置３０を構成する給電側システム制御手段３５ａから可動手段３６に対して前記制御信号が出力される構成となっているのであるが，この実施形態における可動手段３６は，前記給電側システム制御手段３５ａからの前記制御信号によって，まず給電手段３１を「第１の配置」から「第２の配置」へ上昇させ，一次コイル３１ａと二次コイル２１ａの上下の間隔を所定の寸法にするばかりでなく，更に加え，この「第２の配置」の位置を原点として，当該所定の寸法を保ったまま，給電手段３１を，給電手段３１がなす平面に平行な方向の所定の範囲内において，特に給電手段３１の所定地点が，予め設定された複数の任意の座標を有した「第３の配置」に位置するように，前記給電手段３１は予め定められた順序で順次移動させるように構成されている。 The power supply device 30 in this embodiment also controls the movable unit 36 from the power supply side system control means 35a constituting the device 30 in accordance with a charge request signal from the power reception device 20 side provided in the automobile 2. The movable means 36 in this embodiment is configured to output the power supply means 31 from “first arrangement” to “first arrangement” according to the control signal from the power supply side system control means 35a. In addition to setting the vertical distance between the primary coil 31a and the secondary coil 21a to a predetermined dimension, the position of the “second arrangement” is set as the origin, and the predetermined arrangement is made. While maintaining the dimensions, the power supply means 31 is set within a predetermined range in a direction parallel to the plane formed by the power supply means 31, and in particular, a predetermined point of the power supply means 31 is a plurality of preset points. So as to be positioned having the meaning of coordinate "third arrangement of" the power supply unit 31 is configured to sequentially move in a predetermined order.
　一方，給電側システム制御手段３５ａは，給電手段３１が「第２の配置」における所定の寸法になったこと示す，「第２の配置」のリミット信号を受けて，開閉器３３に対する駆動信号を出力し，前記開閉器３３を導通状態にすることによって，駆動回路３２の駆動が始まり，一次コイル３１から二次コイル２１ａの給電が行われる。 On the other hand, the power supply side system control unit 35a receives a limit signal of “second arrangement” indicating that the power supply unit 31 has a predetermined size in the “second arrangement”, and sends a drive signal to the switch 33. By outputting the signal and making the switch 33 conductive, the drive circuit 32 starts to be driven, and the primary coil 31 supplies power to the secondary coil 21a.
　更に，この実施形態における電力給電装置３０には，給電側送信手段３７が備えられており，前記給電側システム制御手段３５ａから出力された制御信号は，電力受電装置２０側にも送信される。 Furthermore, the power supply apparatus 30 in this embodiment is provided with a power supply side transmission means 37, and the control signal output from the power supply side system control means 35a is also transmitted to the power reception apparatus 20 side.
　一方，電力受電装置２０側には，前記制御信号を受信するための受電側受信手段２８が備えられており，受信した前記制御信号は，電力受電装置２０に備えた受電側システム制御手段３５ｂに向けて出力される。前記受電側システム制御手段３５ｂでは，前記制御信号を受けて，当該制御信号から前記給電手段３１の前記所定地点における位置データを取得する。この位置データは，前記給電手段３１が，「第２の配置」である原点から，予め定められた所定の範囲内において，予め定められた順序に基づいて順次「第３の配置」に移動させたときの，それぞれの座標に対応するデータであり，この位置データを受けて前記受電側システム制御手段３５ｂでは，前記給電手段３１の座標を記憶する。更に，前記受電側システム制御手段３５ｂは，前記位置データを受け入れる毎に（言い換えれば，前記給電手段３１が制御信号に応じて前記座標を順次移動していく毎に），前記処理部７を介して得られる，例えば，二次コイル２１に誘起される交流電力の大きさの電力データを充電回路２２から収集すると共に，当該電力データと前記位置データとを対応させたテーブルを作成する。 On the other hand, the power receiving apparatus 20 is provided with a power receiving side receiving means 28 for receiving the control signal, and the received control signal is sent to the power receiving side system control means 35b provided in the power receiving apparatus 20. Is output. The power receiving side system control means 35b receives the control signal and acquires position data of the power feeding means 31 at the predetermined point from the control signal. The position data is obtained by causing the power feeding means 31 to sequentially move to the “third arrangement” based on a predetermined order within a predetermined range from the origin that is the “second arrangement”. In response to this position data, the power receiving system control means 35b receives the position data and stores the coordinates of the power supply means 31. Further, every time the power receiving side system control means 35b receives the position data (in other words, every time the power feeding means 31 sequentially moves the coordinates in accordance with the control signal), the power receiving side system control means 35b passes through the processing section 7. For example, power data of the magnitude of AC power induced in the secondary coil 21 is collected from the charging circuit 22 and a table in which the power data is associated with the position data is created.
　加えて，受電側システム制御手段３５ｂは，給電手段３１の可動範囲における，全ての座標において電力データの取得が終わったなら，得られた電力データの中から，最も二次コイル２１に誘起される交流電力が大きくなる座標データを最適位置情報として出力する。また，前記受電側システム制御手段３５ｂは，主バッテリ２３の電力容量を常時監視して得られる処理部７からのデータに基づいて，主バッテリ２３の電力容量が所定値以上有れば，満充電情報を出力するように構成されている。 In addition, the power-receiving-side system control unit 35b is most induced in the secondary coil 21 from the obtained power data when the acquisition of the power data is completed at all coordinates in the movable range of the power feeding unit 31. Coordinate data that increases AC power is output as optimum position information. The power receiving side system control means 35b is fully charged if the power capacity of the main battery 23 exceeds a predetermined value based on the data from the processing unit 7 obtained by constantly monitoring the power capacity of the main battery 23. It is configured to output information.
　そして，この最適位置情報及び満充電情報は，受電側送信手段２７を介して，最適位置制御信号及び充電完了信号として電力給電装置３０側に送信される。
　電力給電装置３０側の給電側受信手段３８は，前記最適位置制御信号を受けて最適位置情報を給電側システム制御手段３６ａに出力する。給電側システム制御手段３５ａでは，当該最適位置情報に基づいた制御信号を可動手段３６に対して出力し，給電手段３１は，可動手段３６によって，最も二次コイル２１に誘起される交流電力が大きくなる位置である「第３の配置」の座標に配設されるように構成されている。また，給電側システム制御手段３５ａが，前記充電完了信号を受けたなら，可動手段３５に対する制御信号と，開閉器３３に対する駆動信号の出力を止めて，システムを待機状態となるように終了処理する。 Then, the optimum position information and full charge information are transmitted to the power feeding apparatus 30 side as an optimum position control signal and a charge completion signal via the power receiving side transmission means 27.
The power feeding side receiving means 38 on the power feeding device 30 side receives the optimum position control signal and outputs optimum position information to the power feeding side system control means 36a. The power supply side system control means 35 a outputs a control signal based on the optimum position information to the movable means 36, and the power supply means 31 has the largest AC power induced in the secondary coil 21 by the movable means 36. It is comprised so that it may be arrange | positioned at the coordinate of "3rd arrangement | positioning" which is a position. When the power supply side system control means 35a receives the charging completion signal, it stops the output of the control signal for the movable means 35 and the drive signal for the switch 33, and finishes the system so as to enter a standby state. .
　ここで，図７から図８を用いて給電手段３１の動作の具体的な例を示すと共に，システムの処理手順について詳しく説明する。図７は，給電手段３１に着目し，第３実施形態における給電手段３１が，基準点である「第１の配置」から，「第３の配置」の原点としての「第２の配置」へ上昇し，更に，給電手段３１がなす平面に平行な方向に任意の座標を有した「第３の配置」となる動きを模式的に示した図である。この図７において，Ｃは給電手段３１を構成する一次コイル３１ａの略中心を示しており，この中心点Ｃが給電手段３１の前記所定地点である。また，図７中央に示される｛「第２の配置」における給電手段３１の配置図及び「第３の配置」における可動範囲｝の図の，給電手段３１の外側に画かれた破線で示す範囲が，給電手段３１の移動可能な範囲を示すものであり，請求項に記載の所定の範囲である。また，この配置図に画かれた給電手段３１の中央部に示される，グリッドで仕切られた部分は，給電手段３１が前記所定の範囲を動いたときにおける，前記一次コイル３１ａの中心点Ｃの動く範囲を示しており，この範囲内の任意の座標に中心点Ｃが移動したときに，給電手段３１は「第３の配置」に配設されたことになる。尚，この図７の上側に画かれた図は，中心点Ｃが動く座標と，その動きの順序を分かり易く説明するため，前記グリッド部分を取り出して拡大した図である。また，図８は第３実施形態におけるシステムの処理手順を示すものであり，図８の（ａ）部分は電力給電装置３０に備えた給電側システム制御手段３５ａのフローチャート，（ｂ）部分は前記給電側システム制御手段３５ａの処理に伴い行われる，一次コイル３１ａの駆動手順，（ｃ）部分は電力受電装置２０に備えた受電側システム制御手段３５ｂのフローチャートである。 Here, a specific example of the operation of the power supply means 31 will be described with reference to FIGS. 7 to 8, and the processing procedure of the system will be described in detail. FIG. 7 focuses on the power supply means 31, and the power supply means 31 in the third embodiment changes from “first arrangement” as a reference point to “second arrangement” as the origin of “third arrangement”. FIG. 6 is a diagram schematically showing a movement that rises and becomes a “third arrangement” having arbitrary coordinates in a direction parallel to a plane formed by the power feeding means 31. In FIG. 7, C indicates the approximate center of the primary coil 31 a constituting the power supply means 31, and this center point C is the predetermined point of the power supply means 31. Further, the range indicated by the broken line drawn outside the power supply means 31 in the {position diagram of the power supply means 31 in the "second arrangement" and the movable range in the "third arrangement" shown in the center of FIG. Indicates a movable range of the power supply means 31, and is a predetermined range described in the claims. Further, the portion partitioned by the grid shown in the central portion of the power feeding means 31 shown in this layout diagram is the center point C of the primary coil 31a when the power feeding means 31 moves within the predetermined range. The moving range is shown, and when the center point C moves to an arbitrary coordinate within this range, the power feeding means 31 is arranged in the “third arrangement”. Note that the figure drawn on the upper side of FIG. 7 is an enlarged view of the grid portion taken out for easy understanding of the coordinates of the movement of the center point C and the order of the movement. FIG. 8 shows the processing procedure of the system in the third embodiment. FIG. 8 (a) is a flowchart of the power supply side system control means 35a provided in the power supply apparatus 30, and FIG. The driving procedure of the primary coil 31a performed in accordance with the processing of the power supply side system control means 35a, part (c) is a flowchart of the power reception side system control means 35b provided in the power receiving device 20.
　この図７及び図８によれば，給電手段３１が給電前の状態である「第１の配置」にあるときの，一次コイル３１ａの略中心点Ｃの座標（Ｘ，Ｙ，Ｚ）を，基準点（０，０，０）とすると，給電側システム制御手段３５ａは，充電希望信号を受けて（Ｓ１００　Ｙｅｓの場合），可動手段３６に対して制御信号を出力することによって（Ｓ１０２），前記可動手段３６が，給電手段３１を上方に向かってαだけ押し上げられた「第２の配置」に配設し，一次コイル３１ａの略中心点Ｃの座標は，Ｚ軸方向にαだけ上昇した（０，０，α）となる。この中心点Ｃの座標は，「第３の配置」における座標Ｐ（１３）と同じであり，「第３の配置」の原点である。そして，給電手段３１が「第２の配置」に配設されたなら，この配設状態を示す「第２の配置」のリミット信号を受けて（Ｓ１０４　Ｙｅｓの場合），給電側システム制御手段３５ａは，開閉器３３に対して「閉」の駆動信号を出力して（Ｓ１０６），次のステップに移行する（Ｓ１０８）。「第２の配置」でないならば（Ｓ１０４　Ｎｏの場合），ステップ（Ｓ１０２）に戻って処理を繰り返す。 According to FIGS. 7 and 8, the coordinates (X, Y, Z) of the approximate center point C of the primary coil 31a when the power feeding means 31 is in the “first arrangement” that is the state before power feeding, Assuming that the reference point is (0, 0, 0), the power supply side system control means 35a receives the charge request signal (in the case of S100 Yes) and outputs a control signal to the movable means 36 (S102). The movable means 36 is disposed in a “second arrangement” in which the power feeding means 31 is pushed upward by α, and the coordinates of the substantially center point C of the primary coil 31a are raised by α in the Z-axis direction. (0, 0, α). The coordinates of the center point C are the same as the coordinates P (13) in the “third arrangement” and are the origin of the “third arrangement”. If the power supply means 31 is arranged in the “second arrangement”, a limit signal of “second arrangement” indicating this arrangement state is received (in the case of S104 Yes), and the power supply side system control means 35a. Outputs a "closed" drive signal to the switch 33 (S106), and proceeds to the next step (S108). If it is not “second arrangement” (in the case of No in S104), the process returns to Step (S102) and is repeated.
　尚，ステップ（Ｓ１０６）において出力された駆動信号を受けて行われる，一次コイル３１ａの駆動手順（図８の（ｂ）部分で示されるＳ２０６～Ｓ２１２）は，第１実施形態の手順（Ｓ２６～Ｓ３２）と同じであるので，詳細な説明は省略する。 The primary coil 31a drive procedure (S206 to S212 shown in part (b) of FIG. 8) performed in response to the drive signal output in step (S106) is the same as that of the first embodiment (S26 to S212). Since it is the same as S32), detailed description is omitted.
　一方，前記給電側システム制御手段３５ａが，前記充電希望信号を受けていないときは（Ｓ１００　Ｎｏの場合），前記給電側システム制御手段３５ａが，前記可動手段３６に対しシステムを待機状態にするための前記制御信号を出力（「ＯＦＦ」信号）することによって（Ｓ１１８），給電手段３１は，給電手段３１の上面を路面１とフラットな状態となるように収納した，給電前の位置である「第１の位置」に配設されると共に，開閉器３３に対し「開」の駆動信号を出力（「ＯＦＦ」信号）する）ことによって（Ｓ１２０），給電手段３１から受電手段２１に対する電力の供給は行われず，システムは待機状態となる。 On the other hand, when the power supply side system control means 35a has not received the charge request signal (in the case of S100 No), the power supply side system control means 35a places the system in a standby state with respect to the movable means 36. Is output ("OFF" signal) (S118), the power feeding means 31 is the position before power feeding, in which the upper surface of the power feeding means 31 is housed in a flat state with the road surface 1. Supplying electric power from the power supply means 31 to the power reception means 21 by providing an "open" drive signal ("OFF" signal) to the switch 33 (S120). Is not performed, and the system enters a standby state.
　更に，前記給電側システム制御手段３５ａは，開閉器３３に対して「閉」の駆動信号を出力したなら（Ｓ１０６），主バッテリ２３の電力容量を常時監視して得られる処理部７からのデータに基づいて，自動車２を駐車スペース３に停めたときに，主バッテリ２３の電力容量が所定値より低ければ（Ｓ１０８　Ｎｏの場合）充電を開始して次のステップ（Ｓ１１０）へ移行し処理を行う。一方，主バッテリ２３の電力容量が所定値以上あるとき，つまり，前記充電完了信号を受けたときは（Ｓ１０８　Ｙｅｓの場合），可動手段３６に対する制御信号と閉回路３３に対する駆動信号の出力をやめる（Ｓ１１８，Ｓ１２０）ように構成されている。 Further, if the power supply side system control means 35a outputs a drive signal of “closed” to the switch 33 (S106), the data from the processing unit 7 obtained by constantly monitoring the power capacity of the main battery 23. If the power capacity of the main battery 23 is lower than a predetermined value when the automobile 2 is parked in the parking space 3 based on the above, charging is started and the process proceeds to the next step (S110). Do. On the other hand, when the power capacity of the main battery 23 is equal to or greater than a predetermined value, that is, when the charge completion signal is received (Yes in S108), output of the control signal for the movable means 36 and the drive signal for the closed circuit 33 is stopped. (S118, S120).
　また，バッテリ２３の電力容量が所定値より低い場合（Ｓ１０８　Ｎｏの場合），給電側システム制御手段３５ａは，給電手段３１に対して，給電手段３１の高さαを維持したまま，給電手段３１がなす平面に平行な方向の前記所定範囲内における，座標Ｐ（１３）とは異なる任意の座標を有した「第３の配置」に移動するよう，前記可動手段３６に対して制御信号を出力する。 When the power capacity of the battery 23 is lower than the predetermined value (No in S108), the power supply side system control unit 35a maintains the height α of the power supply unit 31 with respect to the power supply unit 31 while maintaining the height α of the power supply unit 31. A control signal is output to the movable means 36 so as to move to the “third arrangement” having an arbitrary coordinate different from the coordinate P (13) within the predetermined range in the direction parallel to the plane formed by To do.
　具体的には，給電側システム制御手段３５ａは，予め定められた順序で出力される「第３の配置」用の制御信号に基づいて，一次コイル３１ａの中心点Ｃを，先ず，一つ目の「第３の配置」における中心点Ｃのポイントである座標Ｐ（１）（２，２，α）に配設するための制御信号を出力する（Ｓ１１０）ことによって，一次コイル３１ａを座標Ｐ（１）に移動させる。一方，給電側システム制御手段３５ａから出力された，前記座標Ｐ（１）に配設するための制御信号は，座標Ｐ（１）の位置データとして出力され（Ｓ１１２），給電側送信手段３７を介して電力受電装置２０側に送信される。 Specifically, the power supply side system control unit 35a first sets the center point C of the primary coil 31a to the first one based on the control signal for “third arrangement” output in a predetermined order. By outputting a control signal for disposing at the coordinates P (1) (2, 2, α) that is the point of the center point C in the “third arrangement” of (S110), the primary coil 31a is moved to the coordinates P. Move to (1). On the other hand, the control signal for disposing at the coordinate P (1) output from the power supply side system control means 35a is output as position data of the coordinate P (1) (S112). Via the power receiving device 20 side.
　更に，給電側システム制御手段３５ａは，予め記憶された座標Ｐ（ｎ）の数ｎ（本発明の実施形態ではｎ＝１，２・・・２５）に基づいて，座標Ｐ（２５）の位置データが出力されるまで（Ｓ１１４　Ｎｏの場合），可動手段３６に対して順次前記座標Ｐ（ｎ）の制御信号を出力して給電手段３１の配設位置を移動させつつ，当該座標Ｐ（ｎ）の位置データを，電力受電装置２０側に順次送出する処理を繰り返し行う（Ｓ１０６～Ｓ１１４）。そして，座標Ｐ（２５）の位置データが出力されたなら（Ｓ１１４　Ｙｅｓの場合），前記電力受電装置２０に備えた受電側システム制御手段３５ｂから送られる，最適位置制御信号を取得する次のステップに移行する（Ｓ１２２）。 Further, the power feeding side system control means 35a determines the position of the coordinate P (25) based on the number n of coordinates P (n) stored in advance (n = 1, 2,... 25 in the embodiment of the present invention). Until the data is output (in the case of No in S114), the control signal of the coordinate P (n) is sequentially output to the movable unit 36 to move the arrangement position of the power supply unit 31, and the coordinate P (n ) Position data is sequentially sent to the power receiving apparatus 20 side (S106 to S114). If the position data of the coordinate P (25) is output (in the case of S114 Yes), the next step of acquiring the optimum position control signal sent from the power receiving side system control means 35b provided in the power receiving device 20 (S122).
　一方，電力受電装置２０側に備えた前記受電側システム制御手段３５ｂは，図８の（ｃ）部分に示されるように，前記給電側システム制御手段３５ａのステップ（Ｓ１１２）において出力された座標Ｐ（１）の位置データを取得し，座標Ｐ（１）の位置データとして記憶する（Ｓ３１２）と共に，前記受電側システム制御手段３５ｂは，給電手段３１が座標Ｐ（１）にある時の，例えば，二次コイル２１ａに誘起される交流電力のデータを，処理部７を介して取得する（Ｓ３１４）。そして，両方のデータを取得したなら，座標Ｐ（１）の位置データと電力データとを対応させたテーブルを作成する（Ｓ３１６）。同様にして，座標がＰ（２）（１，２，α），Ｐ（３）（０，２，α）・・・，Ｐ（２５）（－２，－２，α）と順次移動するのに伴い，これらの座標Ｐ（２），Ｐ（３）・・・，Ｐ（２５）の位置データと，ぞれぞれの座標において二次コイル２１ａに誘起される交流電力の大きさのデータを対比させたテーブルを作成していく（Ｓ３１２～Ｓ３１８　Ｎｏの場合）。そして，前記受電側システム制御手段３５ｂは，すべての座標におけるテーブルが完成したなら（Ｓ３１８　Ｙｅｓの場合），前記テーブルの中から，誘起される交流電力の大きさが一番大きい（ＰＷ　ｍａｘ）の座標Ｐ（ｍ）を抽出し（Ｓ３２０），その座標Ｐ（ｍ）の位置データを最適位置制御信号として，電力給電装置３０に備えた給電側システム制御手段３５ａにフィードバックする（Ｓ３２２）。 On the other hand, the power receiving-side system control means 35b provided on the power receiving device 20 side, as shown in FIG. 8C, shows the coordinates P output in step (S112) of the power-feeding-side system control means 35a. The position data of (1) is acquired and stored as the position data of the coordinate P (1) (S312), and the power receiving side system control means 35b, for example, when the power supply means 31 is at the coordinate P (1), for example , AC power data induced in the secondary coil 21a is acquired via the processing unit 7 (S314). And if both data are acquired, the table which matched the position data of coordinate P (1) and electric power data will be created (S316). Similarly, the coordinates sequentially move as P (2) (1,2, α), P (3) (0,2, α)..., P (25) (− 2, −2, α). Accordingly, the position data of these coordinates P (2), P (3)..., P (25) and the magnitude of the AC power induced in the secondary coil 21a at each coordinate. A table that compares the data is created (in the case of S312 to S318 No). When the table at all coordinates is completed (in the case of S318 Yes), the power receiving side system control means 35b has the largest induced AC power (PW max) among the tables. The coordinate P (m) is extracted (S320), and the position data of the coordinate P (m) is fed back to the power feeding side system control means 35a provided in the power feeding device 30 as an optimum position control signal (S322).
　更に，給電側システム制御手段３５ａでは，座標Ｐ（２５）の位置データが受電側システム制御手段３５ｂに送出したなら（Ｓ１１４　Ｙｅｓの場合），前記受電側システム制御手段３５ｂより送られた最適位置制御信号を取得して，座標Ｐ（ｍ）の位置データを抽出し（Ｓ１２２），この位置データに応じた制御信号を可動手段３６に対して出力する（Ｓ１２４）。可動手段３６は，この制御信号を基に，最も二次コイル２１に誘起される交流電力が大きくなる位置である「第３の配置」の座標Ｐ（ｍ）に給電手段３１を配設するのである。そして，給電側システム制御手段３５ａは，主バッテリ２３の電力容量を常時監視して得られる処理部７からのデータに基づいて，主バッテリ２３の電力容量が所定値より低ければ（Ｓ１２６　Ｎｏの場合），充電を継続する。また，主バッテリ２３の電力容量が所定値より高くなれば（Ｓ１２６　Ｙｅｓの場合），可動手段３６に対する制御信号と閉回路３３に対する駆動信号の出力をやめ（Ｓ１１８，Ｓ１２０），システム待機に至る終了の処理を行う。 Further, in the power feeding side system control means 35a, if the position data of the coordinate P (25) is sent to the power receiving side system control means 35b (in the case of S114 Yes), the optimum position control sent from the power receiving side system control means 35b. A signal is acquired, position data of the coordinate P (m) is extracted (S122), and a control signal corresponding to the position data is output to the movable means 36 (S124). Based on this control signal, the movable means 36 arranges the power supply means 31 at the coordinate P (m) of the “third arrangement” where the AC power induced in the secondary coil 21 is the largest. is there. If the power capacity of the main battery 23 is lower than a predetermined value based on the data from the processing unit 7 obtained by constantly monitoring the power capacity of the main battery 23 (S126 No) ), Continue charging. If the power capacity of the main battery 23 is higher than a predetermined value (in the case of S126, Yes), the control signal for the movable means 36 and the drive signal for the closed circuit 33 are not output (S118, S120), and the system reaches standby. Perform the process.
　尚，この実施形態に示すグリッドの区切り方と，給電手段３１の移動の順番は一例を示すものであり，実施例に限定されるものではない。 Note that the grid separation method and the order of movement of the power supply means 31 shown in this embodiment are merely examples, and are not limited to the examples.
　次に，図９で示される本発明に係る第４実施形態について説明する。この実施形態は前記第３実施形態の異なる実施例であり，その違いは，可動手段３６の取り付け位置の違いである。図９に良く示されるように，この第４実施形態では，可動手段３６は，自動車２側に搭載された電力受電装置側２０の二次コイル２１ａ側に備えられている。 Next, a fourth embodiment according to the present invention shown in FIG. 9 will be described. This embodiment is a different example of the third embodiment, and the difference is the difference in the mounting position of the movable means 36. As well shown in FIG. 9, in the fourth embodiment, the movable means 36 is provided on the secondary coil 21a side of the power receiving device side 20 mounted on the automobile 2 side.
　つまり，この実施例では，一次コイル３１ａは路面１に固定されていて，自動車２に備えられた受電手段２１が，二次コイル２１ａと支持部材である基台２１ｂで一体的に形成されていることによって，この受電手段２１の位置を，可動手段３６で持って「第１の配置」から「第２の配置」を経て，「第３の配置」に替えることができるように構成されているのである。 That is, in this embodiment, the primary coil 31a is fixed to the road surface 1, and the power receiving means 21 provided in the automobile 2 is integrally formed by the secondary coil 21a and the base 21b which is a support member. Thus, the position of the power receiving means 21 is held by the movable means 36 so that it can be changed from the “first arrangement” to the “third arrangement” through the “second arrangement”. It is.
　この実施形態における電力給電装置３０に備えた給電側システム制御手段３５ａは，前記充電希望信号を受けて，電力受電装置２０側に備えた受電側システム制御手段３５ｂに対して，可動手段３６を制御する許可を与える，前記「所定の手続」の応答信号を出力すると共に，前記開閉器３３に対して「閉」の駆動信号を出力するように構成されている。 In this embodiment, the power supply side system control means 35a provided in the power supply apparatus 30 receives the charge request signal and controls the movable means 36 with respect to the power reception side system control means 35b provided on the power reception apparatus 20 side. A response signal of the “predetermined procedure” is given, and a drive signal of “closed” is output to the switch 33.
　一方，この実施形態における前記受電側システム制御手段３５ｂは，電力給電装置３０側からの前記応答信号を受けて，可動手段３６に対して受電手段２１を制御するための制御信号を出力するように構成されている。 On the other hand, the power receiving side system control means 35b in this embodiment receives the response signal from the power feeding device 30 side and outputs a control signal for controlling the power receiving means 21 to the movable means 36. It is configured.
　このように構成された本実施形態を具体的に説明する。起動判定手段２６においてパーキングブレーキが「ＯＮ」であると判定されたなら，前記受電側送信手段２７から充電希望信号を電力給電装置３０側に送出する。そして，その充電希望信号を受けた電力給電装置３０では，前記充電希望信号を受けて，電力給電装置３０に備えた給電側システム制御手段３５ａから，電力受電装置２０に備えた受電側システム制御手段３５ｂに対して，可動手段３６の駆動を許可するための応答信号を，給電側送信手段３７を介して前記電力受電装置２０側に送信する。 This embodiment configured as described above will be specifically described. If it is determined by the activation determination means 26 that the parking brake is “ON”, a charge request signal is sent from the power receiving side transmission means 27 to the power feeding device 30 side. Then, the power supply device 30 that has received the charge request signal receives the charge request signal and receives power from the power supply side system control unit 35 a provided in the power supply device 30 to the power reception side system control unit provided in the power reception device 20. A response signal for permitting the drive of the movable unit 36 is transmitted to the power receiving device 20 side via the power supply side transmitting unit 37 with respect to 35b.
　更に，前記電力受電装置２０には，電力給電装置３０側の給電側送信手段３７からの応答信号を受信する受電側受信手段２８が備えられており，当該応答信号を受けて，受電側受信手段２８から，電力受電装置２０に備えた前記受電側システム制御手段３５ｂに対して前記応答信号を出力する。前記受電側システム制御手段３５ｂは，この応答信号を受けたなら，前記可動手段３６に対して制御信号を送出することによって，受電手段２１が，給電手段３との間隔を狭めるように前記「第２の配置」まで下降すると共に，予め定められたポイントと順序に基づいて「第３の配置」の座標に順次移動するように構成されているのである。 Further, the power receiving device 20 is provided with a power receiving side receiving means 28 for receiving a response signal from the power feeding side transmitting means 37 on the power feeding device 30 side. Upon receiving the response signal, the power receiving side receiving means 20 28, the response signal is output to the power receiving side system control means 35 b provided in the power receiving device 20. When the power receiving side system control means 35b receives this response signal, it sends the control signal to the movable means 36 so that the power receiving means 21 narrows the interval with the power feeding means 3. It is configured to move down to the “second arrangement” and to sequentially move to the coordinates of the “third arrangement” based on a predetermined point and order.
　更に加えて，受電側システム制御手段３５ｂは，前記可動手段３６が，前記受電手段２１を前記「第２の配置」である所定の間隔に配設し終わったことを示す，「第２の配置」のリミット信号を検出すると共に，その結果を駆動許可信号として，前記受電側送信手段２７を介して，電力給電装置３０に備えた給電側システム制御手段３５ａに向けて送出する。 In addition, the power receiving side system control means 35b indicates that the movable means 36 has finished arranging the power receiving means 21 at a predetermined interval which is the “second arrangement”. And the result is sent as a drive permission signal to the power supply side system control means 35a provided in the power supply apparatus 30 via the power reception side transmission means 27.
　給電側システム制御手段３５ａでは，当該駆動許可信号を受けて，開閉器３３に対して「閉」の駆動信号が出力される。そして，この「閉」の駆動信号に基づいて開閉器３３が導通状態となり，駆動回路３２に交流電力が供給され一次コイル３１ａが駆動されるのである。 In response to the drive permission signal, the power supply side system control means 35 a outputs a “closed” drive signal to the switch 33. Based on this “closed” drive signal, the switch 33 becomes conductive, AC power is supplied to the drive circuit 32, and the primary coil 31a is driven.
　つまり，本発明の第４実施形態では，自動車２側の底面に備えた受電手段２１が下降する構成であるが，上述したように，前記電力受電手段２０と前記電力給電装置３０との間で，充電希望信号の受信，及び，それに対する応答信号の受信と言った「所定の手続」が得られない限り，受電手段２１が下降することがないので，自動車側に可動式の受電手段２１を備えても，自動車道等の安全運行に支障は生じない。更に加えて，前記電力受電装置２０から前記電力給電装置３０に対して，前記駆動許可信号が送出されない限り，一次コイル３１ａが駆動されないので，省エネルギーが実現できる。 That is, in the fourth embodiment of the present invention, the power receiving means 21 provided on the bottom surface on the automobile 2 side is lowered, but as described above, between the power receiving means 20 and the power feeding device 30. Unless the “predetermined procedure” such as reception of the charging request signal and reception of the response signal is obtained, the power receiving means 21 will not be lowered, so that the movable power receiving means 21 is provided on the vehicle side. Even if it is prepared, it will not interfere with the safe operation of the expressway. In addition, since the primary coil 31a is not driven unless the drive permission signal is sent from the power receiving device 20 to the power feeding device 30, energy saving can be realized.
　そして，受電側システム制御手段３５ｂにおいて座標データとその座標に対応する電力データのテーブルを作成すると共に，電力データが最大となる座標データを抽出することによって，当該受電側システム制御手段３５ｂは，受電手段２１を最も効率の良い位置の「第３の配置」に配設することができるのである。 Then, the power receiving side system control means 35b creates a table of coordinate data and power data corresponding to the coordinates, and extracts the coordinate data that maximizes the power data, so that the power receiving side system control means 35b receives the power receiving power. The means 21 can be arranged in the “third arrangement” at the most efficient position.
　このように，本発明の第３実施形態及び第４実施形態によれば，前記電力受電装置２０を備えた自動車２を，前記電力給電装置３０を備えた所定の駐車場に停め，少なくともパーキングブレーキを掛け，自動車２を確実に停車状態にすることによって，第３実施形態にあっては，前記電力受電装置２０側から前記電力給電装置３０側に対して充電希望信号が送出され，そして，その充電希望信号を電力給電装置３０が受ける，と言った「所定の手続」を経て，給電手段３１が，給電の効率最も良くなる位置である「第３の配置」に自動的に配設され，一方，第４実施形態にあっては，充電希望信号の受信に加えて，更に，前記電力給電装置３０側から前記電力受電装置２０側に対して，充電希望信号に対する応答信号が送出され，その応答信号を電力受電装置２０側が受ける，と言った「所定の手続」を経て，受電手段２１が，給電の効率最も良くなる位置である「第３の配置」に自動的に配設されると共に，それぞれ配置が完了したことを受けて，開閉器３３を介して交流電力の供給が開始されて一次コイル３１ａが駆動され，二次コイル２１ａとの間で電磁誘導による給電が始まるように構成した。
　これによって，前記第１及び第２実施形態が有する効果に加え，前記電力受電装置２０を搭載した自動車２が，前記電力給電装置３０を備えた駐車スペース３に，多少ラフに駐車してしまって，一次コイル３１ａと二次コイル２１ａが正対しない状態になった場合でも，本発明の第３及び第４実施形態においては，給電手段３１もしくは受電手段２１が，変換効率の最も良くなる「第３の配置」に自動的に配設されることから，二次コイル２１ａ側に効率よく電力を誘起でき，主バッテリ２３に対する充電時間等の短縮が図れるばかりでなく，無駄に電力を消費しないので省エネルギーとなる。 As described above, according to the third and fourth embodiments of the present invention, the vehicle 2 including the power receiving device 20 is stopped at a predetermined parking lot including the power feeding device 30, and at least a parking brake. In the third embodiment, the charging request signal is sent from the power receiving device 20 side to the power feeding device 30 side, and the vehicle 2 is surely stopped. Through a “predetermined procedure” in which the power supply device 30 receives a charge request signal, the power supply means 31 is automatically disposed in the “third arrangement”, which is the position where the efficiency of power supply is maximized, On the other hand, in the fourth embodiment, in addition to receiving the desired charging signal, a response signal for the desired charging signal is sent from the power feeding device 30 side to the power receiving device 20 side. Response Through the “predetermined procedure” that the power receiving device 20 receives the power, the power receiving means 21 is automatically disposed in the “third arrangement” that is the position where the power feeding efficiency is best, In response to the completion of the arrangement, supply of AC power is started via the switch 33, the primary coil 31a is driven, and power supply by electromagnetic induction is started with the secondary coil 21a.
As a result, in addition to the effects of the first and second embodiments, the automobile 2 equipped with the power receiving device 20 is parked somewhat roughly in the parking space 3 provided with the power feeding device 30. In the third and fourth embodiments of the present invention, even when the primary coil 31a and the secondary coil 21a do not face each other, the power feeding means 31 or the power receiving means 21 has the best conversion efficiency. 3 ”is automatically arranged, so that power can be efficiently induced on the secondary coil 21a side, not only can the charging time for the main battery 23 be shortened, but also power is not wasted. It becomes energy saving.
