Description

この発明は、バッテリ搭載車両のための非接触充電システムに関する。   The present invention relates to a contactless charging system for a battery-equipped vehicle.

電気モータによって走行する電気自動車(EV車)や電気モータとガソリンエンジンとの併用によって走行するプラグインハイブリッド車(PHV車)が普及してきている。これらEV車やPHV車にはバッテリが搭載されており、バッテリに蓄えられた電気エネルギーによってモータを駆動することにより車両の走行が行われる。   An electric vehicle (EV vehicle) that travels by an electric motor and a plug-in hybrid vehicle (PHV vehicle) that travels by using an electric motor and a gasoline engine in combination have become widespread. These EV cars and PHV cars are equipped with a battery, and the vehicle is driven by driving a motor with electric energy stored in the battery.

現在、EV車やPHV車用の充電システムとしては、駐車エリア内に設けられた複数の駐車スペースにそれぞれ充電スタンドを設置し、車両が駐車スペースに駐車している間に充電を行う方式が一般的である。また、充電スタンドから車両への電力供給の方法としては、充電スタンドと車両とを専用の充電ケーブルで接続する接触充電システムと、充電スタンドと車両とを非接触状態に保ったまま電磁誘導等の原理を利用して電力供給を行う非接触充電システムとがある。   Currently, as a charging system for EV cars and PHV cars, there is generally used a charging stand installed in each of a plurality of parking spaces provided in a parking area, and charging is performed while the vehicle is parked in the parking space. Is. In addition, as a method of supplying power from the charging stand to the vehicle, a contact charging system that connects the charging stand and the vehicle with a dedicated charging cable, and electromagnetic induction or the like while maintaining the charging stand and the vehicle in a non-contact state. There is a non-contact charging system that uses the principle to supply power.

また、充電スタンドから車両への充電を行う際には、充電スタンドと車両との間で各種制御命令をやり取りする必要がある。充電スタンドと車両とを充電ケーブルで接続する接触充電システムでは、充電ケーブル内に通信線を含めることによって各種制御命令のやり取りを有線通信によって行うことができるが、充電ケーブルを使用しない非接触充電システムの場合には、充電スタンドと車両との間の各種制御命令のやり取りを無線通信等の非接触通信によって行う必要がある。その際、駐車エリア内に複数の充電スタンドが設置されている場合には、車両は何らかの手段で自身が無線通信接続を確立すべき充電スタンドを特定する必要がある。   Further, when charging the vehicle from the charging stand, it is necessary to exchange various control commands between the charging stand and the vehicle. In a contact charging system in which a charging station and a vehicle are connected by a charging cable, various control instructions can be exchanged by wired communication by including a communication line in the charging cable, but a non-contact charging system that does not use a charging cable In this case, it is necessary to exchange various control commands between the charging station and the vehicle by non-contact communication such as wireless communication. At that time, when a plurality of charging stations are installed in the parking area, it is necessary for the vehicle to identify the charging station itself to establish a wireless communication connection by some means.

特許文献1には、車両と、充電スタンドの複数の駐車位置にそれぞれ設けられた給電装置との間で非接触通信を行う装置が記載されている。この非接触通信装置では、車両に設けられた充電装置及び受電コイルと、充電スタンドに設けられた給電装置及び給電コイルとを備えている。また、車両の充電装置と、充電スタンドとの間の無線通信に使用するために、充電装置無線通信部及び充電装置アンテナと、充電スタンド無線通信部及び充電スタンドアンテナとが設けられている。そして、複数の充電スタンドのうち車両が駐車している充電スタンドを特定するために、充電スタンドの各給電装置に設けられた給電コイルより、順番に照合用電力を出力する。車両は、照合用電力を受電コイルで受信すると、充電装置無線通信部から充電装置アンテナを介して無線信号を送信し、無線信号は充電スタンドアンテナを介して充電スタンド無線通信部に受信される。照合用電力の出力から一定時間内に無線信号が充電スタンド無線通信部で受信されない場合、その給電装置の駐車位置には車両が存在しないと判定される。一方、照合用電力の出力から一定時間内に無線信号が充電スタンド無線通信部で受信された場合、その給電装置の駐車位置には車両が存在すると判定される。これにより、車両がどこの充電装置に駐車しているかが判明する。   Patent Document 1 describes a device that performs non-contact communication between a vehicle and a power feeding device provided at each of a plurality of parking positions of a charging stand. This non-contact communication device includes a charging device and a power receiving coil provided in a vehicle, and a power feeding device and a power feeding coil provided in a charging stand. In addition, a charging device wireless communication unit and a charging device antenna, and a charging stand wireless communication unit and a charging stand antenna are provided for use in wireless communication between the vehicle charging device and the charging stand. Then, in order to identify a charging station where the vehicle is parked among the plurality of charging stations, verification power is sequentially output from the power feeding coil provided in each power feeding device of the charging station. When the vehicle receives the verification power by the power receiving coil, the vehicle transmits a wireless signal from the charging device wireless communication unit via the charging device antenna, and the wireless signal is received by the charging station wireless communication unit via the charging stand antenna. When the wireless signal is not received by the charging station wireless communication unit within a predetermined time from the output of the verification power, it is determined that there is no vehicle at the parking position of the power supply device. On the other hand, when a wireless signal is received by the charging station wireless communication unit within a predetermined time from the output of the verification power, it is determined that a vehicle is present at the parking position of the power supply device. As a result, the charging device where the vehicle is parked is determined.

しかしながら、特許文献1に記載の非接触通信方式では、各充電装置毎に照合用電力の出力から一定時間内に無線信号が充電スタンド無線通信部に受信されるか、または受信されないかの判断をするまでの時間を待たなくてはいけないため、車両の駐車位置特定まで時間がかかるといった問題点があった。   However, in the non-contact communication method described in Patent Document 1, it is determined whether or not a wireless signal is received by the charging station wireless communication unit within a predetermined time from the output of the verification power for each charging device. There is a problem that it takes time to specify the parking position of the vehicle because it is necessary to wait for the time to do so.

この発明はこのような問題を解決するためになされたものであり、車両が無線通信接続を確立すべき充電スタンドを簡単かつ確実に特定することができる非接触充電システムを提供することを目的とする。   This invention was made in order to solve such a problem, and it aims at providing the non-contact charge system which can specify the charging station where a vehicle should establish a wireless communication connection easily and reliably. To do.

次に、この発明の実施の形態1に係る非接触充電システムの動作を図2〜図6を参照して説明する。
図3に非接触充電システムのシーケンス例を示す。車両3が充電スタンド2aの所定の駐車位置に駐車すると、充電装置制御装置18が車両3の駐車を検知する(A)。このときの駐車を検知する手段は、車両3のパーキングブレーキの作動を検知するものや、車両3の走行用電源スイッチが切られたことを検知するものなど、任意の手段を用いてよい。
Next, the operation of the non-contact charging system according to Embodiment 1 of the present invention will be described with reference to FIGS.
FIG. 3 shows a sequence example of the non-contact charging system. When the vehicle 3 is parked at a predetermined parking position of the charging stand 2a, the charging device control device 18 detects parking of the vehicle 3 (A). The means for detecting parking at this time may be any means such as a means for detecting the operation of the parking brake of the vehicle 3 or a means for detecting that the traveling power switch of the vehicle 3 is turned off.

充電装置制御装置18が車両3の駐車を検知したら、充電装置制御装置18は充電装置無線通信部19を起動し(B)、充電装置制御装置18は充電装置無線通信部19に対し給電装置探索指示を出す(C)。給電装置探索指示を受けた充電装置無線通信部19は、給電装置探索要求を充電装置アンテナ20を介してブロードキャストで出力する(D)。このとき送信される給電装置探索要求の信号には、充電装置無線通信部19のMACアドレスが含まれている。給電装置4aの給電装置アンテナ13aを介して給電装置探索要求を給電装置無線通信部12aが受信すると、給電装置無線通信部12aは受信通知を給電装置制御装置11aに送信する(E)。給電装置制御装置11aは、給電装置4aの状況を確認し、給電が可能であれば、給電装置無線通信部12aに探索応答指示を出す(F)。給電装置無線通信部12aは、充電装置無線通信部19のMACアドレスを利用し、給電装置アンテナ13aを介して探索応答をユニキャストで出力する(Ga)。このとき送信される探索応答の信号には、給電装置無線通信部12aのMACアドレスが含まれている。なお、給電装置4b、4cについてもそれぞれ給電装置探索要求を受信して(E)、(F)及び(Ga)に相当する(Gb)、(Gc)の動作が行われる。   When the charging device control device 18 detects parking of the vehicle 3, the charging device control device 18 activates the charging device wireless communication unit 19 (B), and the charging device control device 18 searches the charging device wireless communication unit 19 for a power feeding device. An instruction is issued (C). Receiving the power supply device search instruction, the charging device wireless communication unit 19 broadcasts a power supply device search request via the charging device antenna 20 (D). The power supply device search request signal transmitted at this time includes the MAC address of the charging device wireless communication unit 19. When the power feeding device wireless communication unit 12a receives a power feeding device search request via the power feeding device antenna 13a of the power feeding device 4a, the power feeding device wireless communication unit 12a transmits a reception notification to the power feeding device control device 11a (E). The power feeding device control device 11a confirms the status of the power feeding device 4a, and if power feeding is possible, issues a search response instruction to the power feeding device wireless communication unit 12a (F). The power feeding device radio communication unit 12a uses the MAC address of the charging device radio communication unit 19 to output a search response in unicast via the power feeding device antenna 13a (Ga). The search response signal transmitted at this time includes the MAC address of the power supply apparatus wireless communication unit 12a. The power feeding devices 4b and 4c also receive the power feeding device search request, and the operations (Gb) and (Gc) corresponding to (E), (F), and (Ga) are performed.

次に、探索応答を受信した充電装置無線通信部19は、給電装置4a,4b,4cのMACアドレスを含んだ探索応答通知を充電装置制御装置18に送信する(H)。充電装置制御装置18は、図4に示すように、応答のあった給電装置のリストである給電装置リストを作成する(I)。給電装置リストには、応答のあった給電装置の番号と、該給電装置の給電装置無線通信部のMACアドレスが含まれている。さらに、充電装置制御装置18は、給電装置リストに載っている給電装置に対して、後述する照合用電力出力の出力時間を割り振り、給電装置リストに記録する(J)。実施の形態1では、給電装置4a,4b,4cに対して割り振られた出力時間をta,tb,tcとする。給電装置4a,4b,4cに対して割り振られた出力時間ta,tb,tcは、給電装置4a,4b,4cの識別情報である。この出力時間ta,tb,tcは、それぞれ重ならない任意の時間であることが必要であり、また、実施の形態1では例えば1秒以上の任意の時間であることが後述する出力時間の照合に適している。   Next, the charging device wireless communication unit 19 that has received the search response transmits a search response notification including the MAC addresses of the power supply devices 4a, 4b, and 4c to the charging device control device 18 (H). As shown in FIG. 4, the charging device control device 18 creates a power feeding device list that is a list of power feeding devices that have responded (I). The power supply apparatus list includes the number of the power supply apparatus that has responded and the MAC address of the power supply apparatus wireless communication unit of the power supply apparatus. Further, the charging device control device 18 allocates an output time of a later-described verification power output to the power feeding devices on the power feeding device list, and records them in the power feeding device list (J). In the first embodiment, output times allocated to the power feeding apparatuses 4a, 4b, and 4c are ta, tb, and tc. Output times ta, tb, and tc allocated to the power feeding devices 4a, 4b, and 4c are identification information of the power feeding devices 4a, 4b, and 4c. The output times ta, tb, and tc need to be arbitrary times that do not overlap, and in the first embodiment, for example, an arbitrary time of 1 second or longer is used for collating output times described later. Is suitable.

充電装置制御装置18は、出力時間通知指示を充電装置無線通信部19へ送信する(K)。充電装置無線通信部19は、充電装置アンテナ20を介して、給電装置4aの給電装置無線通信部12a及び給電装置4b,4cの図示しない給電装置無線通信部に対して、出力時間通知を各給電装置無線通信部12a及び給電装置4b,4cの図示しない給電装置無線通信部のMACアドレスを利用してユニキャストで出力する(La,Lb,Lc)。給電装置アンテナ13aを介して出力時間通知を受信した給電装置無線通信部12aは、出力時間taを含んだ出力時間通知受信通知を給電装置制御装置11aへ出力する(M)。給電装置4b,4cの図示しない給電装置無線通信部においても、出力時間tb,tcを含んだ出力時間通知受信通知を給電装置4b,4cの図示しない給電装置制御装置へ出力する。給電装置4aの給電装置制御装置11a及び給電装置4b,4cの図示しない給電装置制御装置では、受信した出力時間通知受信通知に含まれる識別情報である出力時間ta,tb,tcに基づき、照合用電力を発生させるために給電コイル6a及び給電装置4b,4cの図示しない給電コイルに供給する電力のパターンを作成する。   The charging device control device 18 transmits an output time notification instruction to the charging device wireless communication unit 19 (K). The charging device wireless communication unit 19 sends an output time notification to the power feeding device wireless communication unit 12a of the power feeding device 4a and the power feeding device wireless communication unit (not shown) of the power feeding devices 4b and 4c via the charging device antenna 20. Using the MAC address of the power supply device wireless communication unit (not shown) of the device wireless communication unit 12a and the power supply devices 4b and 4c, the data is output by unicast (La, Lb, Lc). The power feeding device wireless communication unit 12a that has received the output time notification via the power feeding device antenna 13a outputs an output time notification reception notification including the output time ta to the power feeding device control device 11a (M). The power supply device wireless communication unit (not shown) of the power supply devices 4b and 4c also outputs an output time notification reception notification including the output times tb and tc to a power supply device control device (not shown) of the power supply devices 4b and 4c. The power supply device control device 11a of the power supply device 4a and the power supply device control device (not shown) of the power supply devices 4b and 4c are used for verification based on the output times ta, tb, and tc that are identification information included in the received output time notification reception notification. In order to generate electric power, the pattern of the electric power supplied to the electric power feeding coil 6a and the electric power feeding coil which is not shown in figure of the electric power feeders 4b and 4c is created.

続いて、充電装置制御装置18は、充電装置無線通信部19に対して、出力要求指示を送る(N)。出力要求指示を受け取った充電装置無線通信部19は、充電装置アンテナ20を介して、出力要求をブロードキャストで出力する(O)。給電装置アンテナ13aを介して出力要求を受信した給電装置無線通信部12aは、出力要求通知を給電装置制御装置11aへ出力する(P)。出力要求通知を受信した給電装置制御装置11aは、交流電源10aから供給される電力を電源変換部9aで電圧、周波数を変換し、さらに照合用電力を発生させるための電力に変換して給電装置整合部8aを介して給電コイル6aに供給する(Q)。ここで、照合用電力を発生させるための電力としては、例えば10wから数十w程度の値であり、数kwの充電電力に対して十分弱い電力であればよい。給電装置4b、4cについても同様にそれぞれの図示しない給電装置無線通信部で出力要求を受信し、図示しない給電装置無線通信部は出力要求通知を給電装置4b、4cの図示しない給電装置制御装置に出力し、図示しない給電装置制御装置は、給電装置4b、4cの図示しない交流電源から供給される電力を給電装置4b,4cの図示しない電源変換部にて電圧、周波数を変換しさらに照合用電力を発生させるための電力に変換して、給電装置4b,4cの図示しない給電装置整合部を介して給電装置4b,4cの図示しない給電コイルに照合用電力を発生させるための電力を供給する。   Subsequently, the charging device control device 18 sends an output request instruction to the charging device wireless communication unit 19 (N). Receiving the output request instruction, the charging device wireless communication unit 19 broadcasts the output request via the charging device antenna 20 (O). The power feeding device wireless communication unit 12a that has received the output request via the power feeding device antenna 13a outputs an output request notification to the power feeding device control device 11a (P). The power supply apparatus control device 11a that has received the output request notification converts the power supplied from the AC power supply 10a into a power and a frequency for converting the voltage and frequency by the power supply conversion unit 9a, and further converts the power into power for generating verification power. The power is supplied to the feeding coil 6a through the matching unit 8a (Q). Here, the power for generating the verification power is, for example, a value of about 10 w to several tens w, and may be any power that is sufficiently weak with respect to the charging power of several kw. Similarly, the power supply apparatuses 4b and 4c receive an output request at a power supply apparatus wireless communication unit (not shown), and the power supply apparatus wireless communication unit (not shown) sends an output request notification to a power supply apparatus control device (not shown) of the power supply apparatuses 4b and 4c. The power supply device control device (not shown) outputs the power, which is supplied from an AC power supply (not shown) of the power supply devices 4b and 4c, and converts the voltage and frequency in a power supply conversion unit (not shown) of the power supply devices 4b and 4c, and further power for verification. The power for generating verification power is supplied to the power supply coils (not shown) of the power supply devices 4b and 4c via the power supply device matching unit (not shown) of the power supply devices 4b and 4c.

実施の形態1では、車両3は充電スタンド2aの所定の駐車位置に駐車しているので(図1参照)、給電コイル6aに照合用電力を発生させるための電力を供給すると(R)、給電コイル6aと所定のエアギャップを有しつつ対向している受電コイル7では、電磁誘導の相互作用により照合用電力が発生する(S)。受電コイル7に発生した照合用電力は、照合用電力検出部21にて検出される(T)。図5に示すように、照合用電力検出部21においては、検出値が閾値Thを超える範囲の照合用電力出力時間tを検出する。この照合用電力出力時間tは、識別情報に基づく情報である。ここで、検出値は、電流値であってもよいし、電圧値であってもよい。また、給電装置4a,4b,4cのそれぞれの給電コイル6a及び給電装置4b,4cの図示しない給電コイルへの照合用電力を発生させるための電力は、照合用電力出力時間が、給電装置4a,4b,4cに対して割り振られた識別情報である出力時間ta,tb,tcと一致するように、給電装置4aの給電装置制御装置11a及び給電装置4b,4cの図示しない給電装置制御装置で作成された、照合用電力を発生させるために給電コイル6a及び給電装置4b,4cの図示しない給電コイルに供給する電力のパターンに基づいて制御される。照合用電力検出部21は、照合用電力出力時間tを充電装置制御装置18へ通知する(U)。なお、給電装置4b,4cの図示しない給電コイルにも照合用電力は供給されるが、充電準備シーケンスが実施されている車両3が充電スタンド2b,2cの駐車位置にいないため、受電コイル7が所定のエアギャップを有しつつ対向しておらず、電磁誘導が発生しないので車両3に照合用電力は伝達されない。   In the first embodiment, since the vehicle 3 is parked at a predetermined parking position of the charging stand 2a (see FIG. 1), supplying power for generating verification power to the power supply coil 6a (R) In the power receiving coil 7 facing the coil 6a with a predetermined air gap, verification power is generated by the interaction of electromagnetic induction (S). The verification power generated in the power receiving coil 7 is detected by the verification power detection unit 21 (T). As shown in FIG. 5, the verification power detection unit 21 detects the verification power output time t in a range where the detected value exceeds the threshold Th. This verification power output time t is information based on the identification information. Here, the detected value may be a current value or a voltage value. Further, the power for generating verification power to the power supply coils 6a of the power supply devices 4a, 4b, and 4c and the power supply coils (not shown) of the power supply devices 4b and 4c is the power output time for verification, Created by the power supply device control device 11a of the power supply device 4a and the power supply device control device (not shown) of the power supply devices 4b and 4c so as to coincide with the output times ta, tb, and tc that are identification information assigned to 4b and 4c. Control is performed based on the pattern of power supplied to the power supply coil 6a and the power supply coils (not shown) of the power supply apparatuses 4b and 4c in order to generate verification power. The verification power detection unit 21 notifies the charging device control device 18 of the verification power output time t (U). In addition, although the electric power for collation is supplied also to the electric power feeding coil which is not shown in figure of electric power feeder 4b, 4c, since the vehicle 3 in which the charge preparation sequence is implemented is not in the parking position of charging stand 2b, 2c, the electric power receiving coil 7 The electric power for verification is not transmitted to the vehicle 3 because it has a predetermined air gap but is not opposed and electromagnetic induction does not occur.

充電装置制御装置18では、図6に示すように、通知された、識別情報に基づく情報である照合用電力出力時間tを、給電装置リストに載っている識別情報である出力時間ta,tb,tc(図4参照)と照合し(V)(図3参照)、照合用電力出力時間tと出力時間とが一致する給電装置の番号を特定する。実施の形態1では、照合用電力出力時間tと出力時間taとが一致する給電装置を備える充電スタンド2aに車両3が駐車されていると判断し、図4に示す給電装置リストから給電装置4aの番号と給電装置無線通信部12aのMACアドレスとを取得する。図3に示すように、充電装置制御装置18は、取得したMACアドレスを添えて、充電装置無線通信部19に接続要求指示を送信する(W)。充電装置無線通信部19は、接続要求指示に添えられたMACアドレスを使用して、充電装置アンテナ20を介して、接続要求を給電装置無線通信部12aにユニキャストで送信する(X)。給電装置無線通信部12aは、給電装置アンテナ13aを介して接続要求を受信する。次に、給電装置無線通信部12aは、充電装置無線通信部19に、給電装置アンテナ13aを介して接続応答をユニキャストで送信する(Y)。充電装置無線通信部19は、充電装置アンテナ20を介して接続応答を受信し、以降は充電スタンド2aの給電装置無線通信部12aと車両3の充電装置無線通信部19との間で、無線通信が確立する(Z)。   As shown in FIG. 6, the charging device control device 18 uses the notified power output time t for verification, which is information based on the identification information, as output time ta, tb, which is identification information included in the power supply device list. It collates with tc (see FIG. 4) (V) (see FIG. 3), and specifies the number of the power feeding device whose collation power output time t matches the output time. In the first embodiment, it is determined that the vehicle 3 is parked on the charging stand 2a including the power feeding device in which the matching power output time t matches the output time ta, and the power feeding device 4a is determined from the power feeding device list illustrated in FIG. And the MAC address of the power supply apparatus wireless communication unit 12a are acquired. As illustrated in FIG. 3, the charging device control device 18 transmits a connection request instruction to the charging device wireless communication unit 19 with the acquired MAC address (W). Using the MAC address attached to the connection request instruction, the charging device wireless communication unit 19 transmits the connection request to the power feeding device wireless communication unit 12a by unicast via the charging device antenna 20 (X). The power feeding device radio communication unit 12a receives the connection request via the power feeding device antenna 13a. Next, the power feeding device wireless communication unit 12a transmits a connection response to the charging device wireless communication unit 19 via the power feeding device antenna 13a by unicast (Y). The charging device wireless communication unit 19 receives the connection response via the charging device antenna 20, and thereafter performs wireless communication between the power feeding device wireless communication unit 12a of the charging stand 2a and the charging device wireless communication unit 19 of the vehicle 3. Is established (Z).

図2(a)、(b)に示されるように、無線通信の確立後は、交流電源10aから供給される電力を電源変換部9aで電圧、周波数を変換し、給電装置整合部8aと充電装置整合部14とでインピーダンスのマッチングを行い、給電コイル6aに供給する。給電コイル6aと所定のエアギャップを有しつつ対向している受電コイル7では電磁誘導の相互作用により充電電力が発生する。充電電力は充電装置整合部14を介して整流部15で整流され、電圧、電流の検出のための検出部16を介してバッテリ部17に充電される。   As shown in FIGS. 2A and 2B, after the establishment of wireless communication, the power supplied from the AC power supply 10a is converted in voltage and frequency by the power conversion unit 9a, and charged with the power supply device matching unit 8a.

図7に実施の形態2のシーケンス例を示す。図7において、図3と同じアルファベットは同じ動作を表し、図3のアルファベットに「’」がついているものは、図3の動作に対して変更を加えたものである。充電装置制御装置18が、探索応答通知(H)を受ける動作までは実施の形態1と同じである。その後、充電装置制御装置18で図8のように、給電装置の番号に対しての電力の出力値と、MACアドレスとを備えた給電装置リストを作成する(I’)。続いて、スタンドリスト中の給電装置に対して電力の出力値を割り振り、給電装置リストに記録する(J’)。このとき、各給電装置4a,4b,4cに対する電力の出力値をLVa,LVb,LVcとし、それぞれ異なった値になるようにする。給電装置4a,4b,4cに対して割り振られた電力の出力値LVa,LVb,LVcは給電装置4a,4b,4cの識別情報である。
The operation of the non-contact charging system according to Embodiment 2 of the present invention will be described.
FIG. 7 shows a sequence example of the second embodiment. In FIG. 7, the same alphabet as in FIG. 3 represents the same operation, and the one with “′” added to the alphabet in FIG. 3 is a modification of the operation in FIG. 3. The operation until charging device control device 18 receives the search response notification (H) is the same as that in the first embodiment. After that, as shown in FIG. 8, the charging device control device 18 creates a power supply device list including an output value of power for the power supply device number and a MAC address (I ′). Subsequently, an output value of power is allocated to the power supply devices in the stand list and recorded in the power supply device list (J ′). At this time, output values of electric power to the respective power feeding apparatuses 4a, 4b, and 4c are set to LVa, LVb, and LVc, and are set to different values. Output values LVa, LVb, and LVc of power allocated to the power feeding devices 4a, 4b, and 4c are identification information of the power feeding devices 4a, 4b, and 4c.

充電装置制御装置18は、出力電力値通知指示を充電装置無線通信部19へ送信する(K’)。充電装置無線通信部19は、充電装置アンテナ20を介して、各給電装置4a,4b,4cの給電装置無線通信部に対して、出力電力値通知を各給電装置無線通信部のMACアドレスを利用してユニキャストで出力する(La’,Lb’,Lc’)。給電装置アンテナ13aを介して出力電力値通知を受信した給電装置無線通信部12aは、電力の出力値LVaを含んだ出力電力値通知受信通知を給電装置制御装置11aへ出力する(M’)。給電装置4b,4cの図示しない給電装置無線通信部においても、電力の出力値LVb、LVcを含んだ出力電力値通知受信通知を図示しない給電装置制御装置へ出力する。給電装置4aの給電装置制御装置11a及び給電装置4b,4cの図示しない給電装置制御装置では、受信した出力時間通知受信通知に含まれる識別情報である電力の出力値に基づき、照合用電力を発生させるために給電コイル6a及び給電装置4b,4cの図示しない給電コイルに供給する電力のパターンを作成する。   The charging device control device 18 transmits an output power value notification instruction to the charging device wireless communication unit 19 (K ′). The charging device wireless communication unit 19 uses the MAC address of each power feeding device wireless communication unit to notify the power feeding device wireless communication unit of each of the power feeding devices 4a, 4b, 4c via the charging device antenna 20. And output by unicast (La ′, Lb ′, Lc ′). The power feeding device radio communication unit 12a that has received the output power value notification via the power feeding device antenna 13a outputs an output power value notification reception notification including the power output value LVa to the power feeding device control device 11a (M '). The power supply device wireless communication unit (not shown) of the power supply devices 4b and 4c also outputs an output power value notification reception notification including the power output values LVb and LVc to a power supply device control device (not shown). The power feeding device control device 11a of the power feeding device 4a and the power feeding device control device (not shown) of the power feeding devices 4b and 4c generate the power for verification based on the output value of the power that is the identification information included in the received output time notification reception notification. In order to achieve this, a pattern of power to be supplied to a power supply coil (not shown) of the power supply coil 6a and the power supply apparatuses 4b and 4c is created.

続いて、充電装置制御装置18は、充電装置無線通信部19に対して、出力要求指示を送る(N)。出力要求指示を受け取った充電装置無線通信部19は、充電装置アンテナ20を介して、出力要求をブロードキャストで出力する(O)。給電装置アンテナ13aを介して出力要求を受信した給電装置無線通信部12aは、出力要求通知を給電装置制御装置11aへ出力する(P)。出力要求通知を受信した給電装置制御装置11aは、交流電源10aから供給される電力を電源変換部9aで電圧、周波数を変換し、さらに照合用電力に変換して給電装置整合部8aを介して給電コイル6aに供給する(Q’)。ここで、各出力値としては、例えば10wから数十w程度の値であり、数kwの充電電力に対して十分弱い電力であればよい。給電装置4b、4cについても同様に図示しない給電装置無線通信部でそれぞれ出力要求を受信し、給電装置無線通信部は出力要求通知を給電装置4b、4cの図示しない給電装置制御装置に出力し、給電装置制御装置は、給電装置4b,4cの図示しない交流電源から供給される電力を給電装置4b,4cの図示しない電源変換部で電圧、周波数を変換しさらに照合用電力に変換して、給電装置4b,4cの図示しない給電装置整合部を介して給電装置4b,4cの図示しない給電コイルに照合用電力を供給する。   Subsequently, the charging device control device 18 sends an output request instruction to the charging device wireless communication unit 19 (N). Receiving the output request instruction, the charging device wireless communication unit 19 broadcasts the output request via the charging device antenna 20 (O). The power feeding device wireless communication unit 12a that has received the output request via the power feeding device antenna 13a outputs an output request notification to the power feeding device control device 11a (P). The power supply apparatus control device 11a that has received the output request notification converts the voltage and frequency of the power supplied from the AC power supply 10a by the power supply conversion unit 9a, and further converts it into verification power, via the power supply device matching unit 8a. Supply to the feeding coil 6a (Q '). Here, each output value is a value of about 10 w to several tens w, for example, and may be any power that is sufficiently weak with respect to several kW of charging power. Similarly, the power supply devices 4b and 4c receive output requests at power supply device wireless communication units (not shown), and the power supply device wireless communication units output output request notifications to power supply device control devices (not shown) of the power supply devices 4b and 4c. The power feeding device control device converts the voltage and frequency of power supplied from an AC power source (not shown) of the power feeding devices 4b and 4c into a power for conversion in a power source conversion unit (not shown) of the power feeding devices 4b and 4c, and further converts the power into a power for verification. Power for verification is supplied to a power supply coil (not shown) of the power supply devices 4b and 4c via a power supply device matching unit (not shown) of the devices 4b and 4c.

実施の形態2では、車両3は充電スタンド2aの所定の駐車位置に駐車しているので(図1参照)、給電コイル6aに照合用電力を供給すると(R’)、給電コイル6aと所定のエアギャップを有しつつ対向している受電コイル7では電磁誘導の相互作用により照合用電力が発生する(S’)。受電コイル7に発生した照合用電力は、照合用電力検出部21にて検出される(T’)。図9に示すように、照合用電力検出部21においては、検出値が閾値Thを超える範囲の照合用電力出力値LVを検知する。この照合用電力出力値LVは、識別情報に基づく情報である。ここで、電力値の値は、電流値であってもよいし、電圧値であってもよい。また、給電コイル6a並びに給電装置4b,4cの図示しない給電コイルへの照合用電力は、照合用電力出力値LVが、給電装置4a,4b,4cに対して割り振られた識別情報である出力値LVa,LVb,LVcと一致するように、給電装置4aの給電装置制御装置11a及び給電装置4b,4cの図示しない給電装置制御装置で作成された、照合用電力を発生させるために給電コイル6a及び給電装置4b,4cの図示しない給電コイルに供給する電力のパターンに基づいて制御される。照合用電力検出部21は、照合用電力出力値LVを充電装置制御装置18へ通知する(U’)。なお、給電装置4b,4cの各給電コイルにも照合用電力は供給されるが、充電準備シーケンスが実施されている車両3が充電スタンド2b,2cの駐車位置にいないため、受電コイル7が所定のエアギャップを有しつつ対向しておらず、電磁誘導が発生しないので車両3に照合用電力は伝達されない。   In the second embodiment, since the vehicle 3 is parked at a predetermined parking position of the charging stand 2a (see FIG. 1), when power for verification is supplied to the power supply coil 6a (R ′), the power supply coil 6a and the predetermined power The power receiving coils 7 facing each other with an air gap generate verification power due to electromagnetic induction interaction (S ′). The verification power generated in the power receiving coil 7 is detected by the verification power detection unit 21 (T ′). As shown in FIG. 9, the verification power detection unit 21 detects a verification power output value LV in a range where the detected value exceeds the threshold Th. The verification power output value LV is information based on the identification information. Here, the power value may be a current value or a voltage value. The power for collation to the power supply coil (not shown) of the power supply coil 6a and the power supply devices 4b and 4c is an output value in which the power output value for verification LV is identification information assigned to the power supply devices 4a, 4b and 4c. In order to match with LVa, LVb, and LVc, the power feeding coil 6a and the power feeding device 6a for generating verification power generated by the power feeding device control device 11a of the power feeding device 4a and the power feeding device control device (not shown) of the power feeding devices 4b and 4c and Control is performed based on a pattern of power supplied to a power supply coil (not shown) of the power supply apparatuses 4b and 4c. The matching power detection unit 21 notifies the charging device control device 18 of the matching power output value LV (U ′). In addition, although the electric power for collation is supplied also to each electric power feeding coil of electric power feeder 4b, 4c, since the vehicle 3 in which the charge preparation sequence is implemented is not in the parking position of charging stand 2b, 2c, the electric power receiving coil 7 is predetermined. Therefore, the electric power for verification is not transmitted to the vehicle 3 because no electromagnetic induction occurs.

充電装置制御装置18では、図10に示すように、通知された、識別情報に基づく情報である照合用電力出力値LVを、給電装置リストに載っている識別情報である出力値LVa、LVb,LVc(図8参照)と照合し、検出した照合用電力出力値LVと出力値とが一致する給電装置の番号を特定する。実施の形態2では、照合用電力出力値LVと出力値LVaとが一致する給電装置を備える充電スタンド2aに車両3が駐車されていると判断し、図8に示す給電装置リストから給電装置4aの番号と給電装置無線通信部12aのMACアドレスとを取得する。その後の動作は実施の形態1と同じである。   As shown in FIG. 10, the charging device control device 18 uses the notified power output value LV for verification, which is information based on the identification information, as output values LVa, LVb, which are identification information included in the power supply device list. LVc (see FIG. 8) is collated, and the number of the power feeding device whose output value matches the detected collation power output value LV is specified. In the second embodiment, it is determined that the vehicle 3 is parked on the charging stand 2a including a power supply device having a matching power output value LV and an output value LVa, and the power supply device 4a is determined from the power supply device list illustrated in FIG. And the MAC address of the power supply apparatus wireless communication unit 12a are acquired. Subsequent operations are the same as those in the first embodiment.

このように、充電装置5は給電装置4a,4b,4cに、それぞれ異なる識別情報である出力値LVa,LVb,LVcを割り振って送信し、出力値LVa,LVb,LVcを受信した給電装置4a,4b,4cは、出力値LVa,LVb,LVcに基づいて、照合用電力を発生させるために給電コイル6a及び給電装置4b,4cの図示しない給電コイルに供給する電力のパターンを生成し、照合用電力を発生させるために給電コイル6a及び給電装置4b,4cの図示しない給電コイルに供給する電力のパターンは、照合用電力を照合用電力検出部21で検出する際に、出力値LVa,LVb,LVcに基づく情報である照合用電力出力値LVを照合用電力検出部21が検出できるように生成されており、給電コイル6a及び給電装置4b,4cの図示しない給電コイルから照合用電力を出力し、受電コイル7に照合用電力が入力され、照合用電力を照合用電力検出部21が検出し、充電装置5が、出力値LVa,LVb,LVcと、照合用電力出力値LVとを照合することで、実施の形態1と同じ効果が得られる。   As described above, the charging device 5 allocates and transmits the output values LVa, LVb, and LVc, which are different identification information, to the power feeding devices 4a, 4b, and 4c, and receives the output values LVa, LVb, and LVc. 4b and 4c generate power patterns supplied to the power supply coil 6a and the power supply coils (not shown) of the power supply apparatuses 4b and 4c to generate power for verification based on the output values LVa, LVb, and LVc. The pattern of power supplied to the power supply coil 6a and the power supply coils (not shown) of the power supply devices 4b and 4c to generate power is the output value LVa, LVb, when the verification power detection unit 21 detects the verification power. The verification power output value LV, which is information based on the LVc, is generated so that the verification power detection unit 21 can detect the power supply coil 6 a and the power supply device 4. , 4c is output from the power supply coil (not shown), the verification power is input to the power receiving coil 7, the verification power detection unit 21 detects the verification power, and the charging device 5 outputs the output values LVa, LVb. , LVc and collation power output value LV, the same effect as in the first embodiment can be obtained.
