　以下、実施の形態について図面を参照して説明する。図１は、実施の形態の電気自動車（又はプラグインハイブリッド自動車など）の充電システムの構成を示す図である。 Hereinafter, embodiments will be described with reference to the drawings. FIG. 1 is a diagram illustrating a configuration of a charging system of an electric vehicle (or a plug-in hybrid vehicle) according to an embodiment.
　充電スタンド（充電装置）１１は、交流電源に接続されており、充電ケーブル１２を介して車両１３のバッテリを充電するための電力を供給する。車両１３の側面には充電ケーブル１２の先端のプラグを挿入する挿入口１４が設けられている。 The charging stand (charging device) 11 is connected to an AC power supply and supplies power for charging the battery of the vehicle 13 via the charging cable 12. An insertion port 14 for inserting a plug at the tip of the charging cable 12 is provided on the side surface of the vehicle 13.
　送信機（無線キーなど）１５は無線信号の送信機能を有し、本体表面のボタンを操作することで、車両１３のドアを施錠又は解錠するため、あるいはトランクを開けるための認証コードを無線信号として送信することができる。 The transmitter (wireless key or the like) 15 has a function of transmitting a wireless signal, and by operating a button on the surface of the main body, an authentication code for locking or unlocking the door of the vehicle 13 or opening a trunk is wireless.

Then, authentication can be easily performed by wirelessly transmitting an authentication code from the transmitter 15 to the charging stand 11.
　図２（Ａ）は充電スタンド１１の構成を示す図であり、図２（Ｂ）は送信機１５の構成を示す図である。 2A is a diagram showing a configuration of the charging stand 11, and FIG. 2B is a diagram showing a configuration of the transmitter 15. FIG.

When the matching authentication code is registered, the power supply circuit 25 is switched from the off state to the on state, and the alternating voltage is supplied to the vehicle 13. The power supply circuit 25 can be realized by a switch, for example. Note that the receiving circuit 22 may have an A / D converter, convert an analog signal into digital data, and output the digital data to the control circuit 23.

The switches SW1 to SW3 are switches for wirelessly transmitting, for example, a code for unlocking the door of the vehicle 13, a code for locking, a code for opening a trunk, and the like. The memory 34 stores authentication codes corresponding to the switches SW1 to SW3.
　制御回路３１は、スイッチＳＷ１～ＳＷ３の内の何れのスイッチが操作されたかを判定し、操作されたスイッチＳＷ１～ＳＷ３に対応する認証コードをメモリ３４から読み出し、読み出した認証コードを送信回路３２に出力する。 The control circuit 31 determines which of the switches SW1 to SW3 has been operated, reads the authentication code corresponding to the operated switch SW1 to SW3 from the memory 34, and sends the read authentication code to the transmission circuit 32.

　充電スタンド１１の制御回路２３は、登録ボタンが押下されたか否かを判定する（Ｓ１１）。登録ボタンが押下されたのを検出するまでステップＳ１１の処理を繰り返す。 The control circuit 23 of the charging station 11 determines whether or not the registration button has been pressed (S11). Step S11 is repeated until it is detected that the registration button has been pressed.
　利用者は、登録ボタンを操作した後、送信機１５のボタンを操作して登録する認証コードを無線送信する（Ｓ１２）。 After operating the registration button, the user wirelessly transmits an authentication code to be registered by operating the button of the transmitter 15 (S12).
　充電スタンド１１の制御回路２３は、認証コードを受信したか否かを判定する（Ｓ１３）。認証コードを受信するまでステップＳ１３の処理を繰り返す。 The control circuit 23 of the charging station 11 determines whether or not an authentication code has been received (S13). Step S13 is repeated until the authentication code is received.
　認証コードを受信した場合には（Ｓ１３、受信）、ステップＳ１４に進み、受信した認証コードを充電が許可された車両１３の認証コードとして登録する。 When the authentication code is received (S13, reception), the process proceeds to step S14, and the received authentication code is registered as the authentication code of the vehicle 13 that is allowed to be charged.
　上記の処理を車両１３の利用者がそれぞれ行うことで、各車両１３の認証コードを充電スタンド１１に登録することができる。 When the user of the vehicle 13 performs the above processing, the authentication code of each vehicle 13 can be registered in the charging stand 11.
　次に、認証コードの登録を行った後の認証コードの照合処理について、図４のフローチャートを参照して説明する。 Next, the verification process of the authentication code after the registration of the authentication code will be described with reference to the flowchart of FIG.
　充電スタンド１１の制御回路２３は、送信機１５から認証コードを受信したか否かを判定する（Ｓ２１）。認証コードを受信するまでステップＳ２１の処理を繰り返す。 The control circuit 23 of the charging station 11 determines whether an authentication code is received from the transmitter 15 (S21). The process of step S21 is repeated until the authentication code is received.
　認証コードを受信した場合には（Ｓ２１、受信）、ステップＳ２２に進み、受信した認証コードと、メモリ２４に記憶されている認証コードを順に照合する。 When the authentication code is received (S21, reception), the process proceeds to step S22, and the received authentication code and the authentication code stored in the memory 24 are collated in order.
　次に、照合結果が合致したか否かを判定する（Ｓ２３）。ステップＳ２３の処理では、受信した認証コードと一致する認証コードがメモリ２４に登録されているか否かを判断する。 Next, it is determined whether or not the collation result matches (S23). In the process of step S23, it is determined whether an authentication code that matches the received authentication code is registered in the memory 24 or not.
　照合結果が合致しない場合、つまり一致する認証コードがメモリ２４に登録されていない場合には（Ｓ２３、否）、ステップＳ２４に進み、認証エラーであることを通知する。 If the verification result does not match, that is, if the matching authentication code is not registered in the memory 24 (S23, No), the process proceeds to step S24, and an authentication error is notified.
　他方、照合結果が合致した場合、つまり送信機１５から送信された認証コードと一致する認証コードがメモリ２４に登録されている場合には、その車両は充電が許可された車両であるので、ステップＳ２５に進み、交流電力の供給を開始する。ステップＳ２５の処理では、制御回路２３が電力供給回路２５をオン状態に切り換え、交流電力が車両１３に供給されるようにする。 On the other hand, if the collation results match, that is, if an authentication code that matches the authentication code transmitted from the transmitter 15 is registered in the memory 24, the vehicle is a vehicle that is allowed to be charged. Proceeding to S25, supply of AC power is started. In the process of step S <b> 25, the control circuit 23 switches the power supply circuit 25 to the on state so that AC power is supplied to the vehicle 13.
　上述した実施の形態によれば、車両１３のドアの解錠又は施錠を行う際に使用する送信機１５を用いて充電スタンド１１との間で簡易に認証を行うことができる。すなわち、特別な認証手段を使用せずに、車両１３のドアを解錠するための送信機１５を利用して認証を行うことができる。 According to the above-described embodiment, authentication can be easily performed with the charging stand 11 using the transmitter 15 used when unlocking or locking the door of the vehicle 13. That is, authentication can be performed using the transmitter 15 for unlocking the door of the vehicle 13 without using any special authentication means.
　上述した実施の形態では、送信機１５のボタンを操作して認証コードを送信しているが、ボタンを操作しなくとも認証コードが送信されるようにしても良い。例えば、利用者が充電スタンド１１に近づき、充電スタンド１１と送信機１５との間で無線通信が可能となったとき、送信機１５から自動的に認証コードが送信されるようにしても良い。この場合、認証時にボタンを操作する必要が無くなるので、利用者は認証のための特別な操作を行わずに充電を行うことができる。 In the above-described embodiment, the authentication code is transmitted by operating the button of the transmitter 15, but the authentication code may be transmitted without operating the button. For example, the authentication code may be automatically transmitted from the transmitter 15 when the user approaches the charging station 11 and wireless communication becomes possible between the charging station 11 and the transmitter 15. In this case, since it is not necessary to operate the button at the time of authentication, the user can perform charging without performing a special operation for authentication.
