Description

本発明は、充電ステーションからケーブルを介して車両に搭載される充電制御装置に電力を供給する車両充電システムに関する。   The present invention relates to a vehicle charging system that supplies electric power from a charging station to a charging control device mounted on a vehicle via a cable.

図７は、従来の車両充電システムを示す図である。
図７に示す車両充電システム７０は、電気自動車やプラグインハイブリット自動車などの車両に搭載される充電制御装置７１と、その充電制御装置７１に電力を供給する充電ステーション７２とを有して構成される。 FIG. 7 is a diagram showing a conventional vehicle charging system.
A vehicle charging system 70 shown in FIG. 7 includes a charging control device 71 mounted on a vehicle such as an electric vehicle or a plug-in hybrid vehicle, and a charging station 72 that supplies electric power to the charging control device 71. The

充電制御装置７１は、充電器７３と、充電制御回路７４と、ＰＬＣ（Power Line Communications）ユニット７５と、ケーブル外れ検出回路７６と、インレット７７と、メモリ７８とを備えて構成される。   The charge control device 71 includes a charger 73, a charge control circuit 74, a PLC (Power Line Communications) unit 75, a cable disconnection detection circuit 76, an inlet 77, and a memory 78.

充電ステーション７２は、商用電源７９と、ケーブル８０と、ケーブル８０の端部に設けられるプラグ８１と、商用電源７９とケーブル８０との間に設けられるリレー８２と、送電制御回路８３と、ＰＬＣユニット８４と、認証回路８５とを備えて構成される。   The charging station 72 includes a commercial power source 79, a cable 80, a plug 81 provided at an end of the cable 80, a relay 82 provided between the commercial power source 79 and the cable 80, a power transmission control circuit 83, and a PLC unit. 84 and an authentication circuit 85.

まず、車両の所有者（以下、ユーザという）によりプラグ８１がインレット７７に接続される。すると、ケーブル外れ検出回路７６は、プラグ８１がインレット７７に接続されたことを検出し、その旨を示す信号を充電制御回路７４に出力する。   First, the plug 81 is connected to the inlet 77 by the owner of the vehicle (hereinafter referred to as a user). Then, the cable disconnection detection circuit 76 detects that the plug 81 is connected to the inlet 77 and outputs a signal indicating that to the charge control circuit 74.

次に、充電制御回路７４は、メモリ７８に記憶される車両ＩＤをＰＬＣユニット７５からケーブル８０を介して充電ステーション７２のＰＬＣユニット８４に送信する。
次に、認証回路８５は、ＰＬＣユニット８４で受信された識別情報に基づいて充電が許可された車両であるか否かの認証処理を行い、その認証結果をＰＬＣユニット８４及び送電制御回路８３にそれぞれ出力する。このとき、認証結果が成功である場合、送電制御回路８３は、リレー８２を接続して商用電源７９とケーブル８０とを電気的に接続する。 Next, the charging control circuit 74 transmits the vehicle ID stored in the memory 78 from the PLC unit 75 to the PLC unit 84 of the charging station 72 via the cable 80.
Next, the authentication circuit 85 performs an authentication process as to whether or not the vehicle is allowed to be charged based on the identification information received by the PLC unit 84, and sends the authentication result to the PLC unit 84 and the power transmission control circuit 83. Output each. At this time, if the authentication result is successful, the power transmission control circuit 83 connects the commercial power supply 79 and the cable 80 by connecting the relay 82.

次に、ＰＬＣユニット８４は、認証結果をケーブル８０を介して充電制御装置７１のＰＬＣユニット７５に送信する。
次に、充電制御回路７４は、ＰＬＣユニット７５で受信された認証結果が成功である場合、充電器７３の動作を制御し、ケーブル８０を介して充電ステーション７２から供給される電力により充電池８６を充電する。 Next, the PLC unit 84 transmits the authentication result to the PLC unit 75 of the charge control device 71 via the cable 80.
Next, when the authentication result received by the PLC unit 75 is successful, the charging control circuit 74 controls the operation of the charger 73 and uses the power supplied from the charging station 72 via the cable 80 to recharge the battery 86. To charge.

そして、充電制御回路７４は、充電池８６の充電状態がユーザにより設定される充電状態になると、充電器７３の動作を停止させる。また、送電制御回路８３は、充電池８６の充電状態がユーザにより設定される充電状態になると、リレー８２を切断する。   Then, the charging control circuit 74 stops the operation of the charger 73 when the charging state of the rechargeable battery 86 becomes a charging state set by the user. Further, the power transmission control circuit 83 disconnects the relay 82 when the charging state of the rechargeable battery 86 becomes a charging state set by the user.

このような車両充電システム７０において、充電中にケーブル外れが発生すると、充電制御回路７４は、充電器７３の動作を停止する。例えば、車両キーと車両との間の無線通信が不可能なとき、ケーブル外れ検出回路７６によりプラグ８１がインレット７７から外れたことが検出されると、充電中にケーブル外れが発生したと判断することが考えられる（例えば、特許文献１参照）。   In such a vehicle charging system 70, when a cable disconnection occurs during charging, the charging control circuit 74 stops the operation of the charger 73. For example, when wireless communication between the vehicle key and the vehicle is not possible, if the cable disconnection detection circuit 76 detects that the plug 81 is disconnected from the inlet 77, it is determined that cable disconnection has occurred during charging. (For example, refer to Patent Document 1).

しかしながら、このときＰＬＣ通信を行うことができないため、充電ステーション７２へケーブル外れが発生したことを通達することができず、商用電源７９とケーブル８０とが接続されたままになってしまう。   However, since PLC communication cannot be performed at this time, the charging station 72 cannot be notified that the cable has been disconnected, and the commercial power supply 79 and the cable 80 remain connected.

そこで、例えば、充電中にＰＬＣ通信が切断されたことをＰＬＣユニット８４が検出すると、送電制御回路８３が充電中にケーブル外れが発生したと判断してリレー８２を切断することが考えられる（例えば、特許文献２参照）。   Thus, for example, when the PLC unit 84 detects that the PLC communication has been disconnected during charging, the power transmission control circuit 83 may determine that a cable disconnection has occurred during charging and disconnect the relay 82 (for example, , See Patent Document 2).

また、例えば、無線により車両からユーザが携帯する警告発生装置に充電中のケーブル外れを通達するシステムを利用して、充電中のケーブル外れを充電制御装置７１から充電ステーション７２へ通達することも考えられる（例えば、特許文献３参照）。   Further, for example, it is also possible to communicate the disconnection of the charging cable from the charging control device 71 to the charging station 72 using a system that wirelessly passes the disconnection of the charging cable from the vehicle to the alarm generation device carried by the user. (See, for example, Patent Document 3).

しかしながら、ＰＬＣ通信を利用して充電中のケーブル外れを充電ステーション７２側で判断する場合、充電ステーション７２側は、ケーブル外れが発生したときの車両の状態を判別することができない。   However, when the disconnection of the cable being charged is determined on the charging station 72 side using the PLC communication, the charging station 72 side cannot determine the state of the vehicle when the cable disconnection occurs.

また、無線により車両から警告発生装置に充電中のケーブル外れを通達するシステムを利用して、充電中のケーブル外れを充電制御装置７１から充電ステーション７２へ通達する場合、公共の充電施設など１つの場所に複数の充電ステーション７２が設置されている環境では、充電ステーション７２がどの車両の充電制御装置７１から送信された情報であるかを判別することができない。   Further, when a cable disconnection during charging is communicated from the vehicle to the warning generation device by radio from the vehicle to the charging station 72 from the charging control device 71, one charging facility such as a public charging facility is used. In an environment where a plurality of charging stations 72 are installed in a place, it is impossible to determine which vehicle charging control device 71 is the information transmitted from the charging control device 71 of the vehicle.

本発明は、１つの場所に複数の充電ステーションが設置されている環境において充電中にケーブル外れが発生した場合、どの車両がどのような状態でケーブル外れが発生したかを充電ステーション側で判別することが可能な車両充電システムを提供することを目的とする。   According to the present invention, when a cable disconnection occurs during charging in an environment where a plurality of charging stations are installed in one place, the charging station side determines which vehicle has the cable disconnected and in what state. It is an object of the present invention to provide a vehicle charging system that can be used.

When it is detected that the controller is disconnected, the monitoring information indicating the monitoring contents by the monitoring means is displayed on the charging station. Vehicle-side wireless communication means for transmitting, and the charging station uses the identification information received in the power line communication and the charging station-side power line communication means for receiving the identification information from the charging control device via the cable. And establishing wireless communication with the charging control device, and wirelessly receiving the monitoring information from the charging control device, and the monitoring received by the charging station side wireless communication device Cable disconnection handling means for performing a predetermined operation based on the information.

これにより、充電ステーションから充電制御装置に電力が供給されているときにケーブル外れが発生した場合、識別情報により無線通信が確立されている充電ステーションに充電制御装置から監視情報が無線通信により送信されるため、１つの場所に複数の充電ステーションが設置されている環境において充電中にケーブル外れが発生した場合しても、どの車両がどのような状態でケーブル外れが発生したかを充電ステーション側で判別することができる。   As a result, when the cable disconnection occurs when power is supplied from the charging station to the charging control device, the monitoring information is transmitted from the charging control device by wireless communication to the charging station where wireless communication is established by the identification information. Therefore, even if a cable disconnection occurs during charging in an environment where multiple charging stations are installed in one place, the charging station side can determine which vehicle has been disconnected and in what state. Can be determined.

また、前記充電ステーションは、前記充電ステーション側無線通信手段において受信した前記監視情報を基に前記充電制御装置へ電力の供給停止を制御する送信制御手段を備えるように構成してもよい。   In addition, the charging station may include a transmission control unit that controls a supply stop of power to the charging control device based on the monitoring information received by the charging station side wireless communication unit.

また、前記充電ステーションは、前記ケーブルが前記充電ステーションから外れたことを検出する第２のケーブル外れ検出手段を備え、前記充電ステーション側無線通信手段は、前記第２のケーブル外れ検出手段により前記ケーブルが前記充電ステーションから外れたことが検出されると、監視情報要求を前記充電制御装置に送信するとともに、前記充電制御装置から前記監視情報及び前記識別情報を受信し、前記車両側無線通信手段は、前記監視情報要求を前記充電ステーションから受信すると、前記監視情報及び前記識別情報を前記充電ステーションに送信するように構成してもよい。   In addition, the charging station includes a second cable disconnection detecting unit that detects that the cable has disconnected from the charging station, and the charging station side wireless communication unit is configured to detect the cable by the second cable disconnection detecting unit. Is detected from the charging station, the monitoring information request is transmitted to the charging control device, and the monitoring information and the identification information are received from the charging control device. When the monitoring information request is received from the charging station, the monitoring information and the identification information may be transmitted to the charging station.

次に、充電ステーション１２は、ＰＬＣユニット８４において接続応答を受信すると、ＰＬＣユニット８４からケーブル８０を介して充電制御装置１１のＰＬＣユニット７５にＰＬＣ通信により車両ＩＤ（IDentification）要求を送信する（Ｓ３）。   Next, when receiving a connection response in the PLC unit 84, the charging station 12 transmits a vehicle ID (IDentification) request by PLC communication from the PLC unit 84 to the PLC unit 75 of the charging control apparatus 11 via the cable 80 (S3). ).

次に、充電制御装置１１は、ＰＬＣユニット７５において車両ＩＤ要求を受信すると、ＰＬＣユニット７５からケーブル８０を介して充電ステーション１２のＰＬＣユニット８４にＰＬＣ通信によりメモリ７８に記憶される車両ＩＤ（識別情報）を送信する（Ｓ４）。   Next, when the charge control device 11 receives the vehicle ID request in the PLC unit 75, the vehicle ID (identification) stored in the memory 78 by PLC communication from the PLC unit 75 to the PLC unit 84 of the charging station 12 via the cable 80. Information) is transmitted (S4).

次に、充電ステーション１２は、ＰＬＣユニット８４において車両ＩＤを受信すると、その車両ＩＤを用いて充電が許可された車両であるか否かの認証処理を認証回路８５において行う（Ｓ５）。   Next, when the charging station 12 receives the vehicle ID in the PLC unit 84, the authentication circuit 85 performs authentication processing as to whether or not the vehicle is allowed to be charged using the vehicle ID (S5).

次に、充電ステーション１２は、その認証結果をＰＬＣユニット８４からケーブル８０を介して充電制御装置１１のＰＬＣユニット７５にＰＬＣ通信により送信する（Ｓ６）。
次に、充電制御装置１１は、ＰＬＣユニット７５において認証結果を受信すると、充電制御回路７４において認証結果が確認され、認証結果が成功であると、ＰＬＣユニット７５からケーブル８０を介して充電ステーション１２のＰＬＣユニット８４にＰＬＣ通信により電力供給要求を送信する（Ｓ７）。 Next, the charging station 12 transmits the authentication result from the PLC unit 84 to the PLC unit 75 of the charging control apparatus 11 via the cable 80 by PLC communication (S6).
Next, when the charging control device 11 receives the authentication result in the PLC unit 75, the charging control circuit 74 confirms the authentication result, and if the authentication result is successful, the charging station 12 via the cable 80 from the PLC unit 75. A power supply request is transmitted to the PLC unit 84 by PLC communication (S7).

次に、充電ステーション１２は、ＰＬＣユニット８４において電力供給要求を受信すると、送電制御回路８３においてリレー８２を接続し（Ｓ８）、ＰＬＣユニット８４からケーブル８０を介して充電制御装置１１のＰＬＣユニット７５にＰＬＣ通信により充電許可信号を送信する（Ｓ９）。   Next, when the charging station 12 receives the power supply request in the PLC unit 84, the relay 82 is connected in the power transmission control circuit 83 (S8), and the PLC unit 75 of the charging control device 11 from the PLC unit 84 via the cable 80 is connected. A charge permission signal is transmitted by PLC communication (S9).

次に、充電制御装置１１は、ＰＬＣユニット７５において充電許可信号を受信すると、充電制御回路７４において充電器７３の動作制御を開始するとともに、充電状態と車両状態の監視を開始し、充電状態をＰＬＣ通信により充電ステーション１２に送信する（Ｓ１０）。例えば、充電制御装置１１は、充電池８６の充電量や充電器７３から充電池８６に出力される電圧及び電流などの充電状態と、ケーブル外れ検出回路７６の出力、防犯センサ１３から出力される侵入者検知信号（車両内に侵入者がいる旨を示す信号）、スマートエントリ装置１４から出力されるユーザ不在信号（ユーザが車両付近にいない旨を示す信号）、外部から入力されるイグニッション操作信号（イグニッションがオンされた旨を示す信号）、又は外部から入力される車両駆動信号（車両が移動された旨を示す信号）などの車両状態を監視する。   Next, when the charge control device 11 receives the charge permission signal in the PLC unit 75, the charge control circuit 74 starts operation control of the charger 73, starts monitoring the charge state and the vehicle state, and sets the charge state. It transmits to the charging station 12 by PLC communication (S10). For example, the charge control device 11 outputs the charge amount of the rechargeable battery 86 and the charge state such as the voltage and current output from the charger 73 to the rechargeable battery 86, the output of the cable disconnection detection circuit 76, and the security sensor 13.

次に、充電制御装置１１は、無線ユニット１５から充電ステーション１２の無線ユニット１６に無線通信により車両ＩＤを送信する（Ｓ１１）。
次に、充電ステーション１２は、無線ユニット１６において車両ＩＤを受信すると、無線通信で受信した車両ＩＤとＰＬＣ通信で受信した車両ＩＤとが一致するか否かを確認し（Ｓ１２）、一致する場合、無線ユニット１６から充電制御装置１１の無線ユニット１５に無線通信により接続応答を送信する（Ｓ１３）。 Next, the charging control device 11 transmits the vehicle ID from the wireless unit 15 to the wireless unit 16 of the charging station 12 by wireless communication (S11).
Next, when the wireless unit 16 receives the vehicle ID in the wireless unit 16, the charging station 12 checks whether or not the vehicle ID received by wireless communication matches the vehicle ID received by PLC communication (S12). Then, a connection response is transmitted from the wireless unit 16 to the wireless unit 15 of the charging control device 11 by wireless communication (S13).

次に、充電制御装置１１は、無線ユニット１５において接続応答を受信すると、充電ステーション１２と無線通信が確立したことを確認する（Ｓ１４）。
次に、充電制御装置１１は、充電制御回路７４において充電を終了するか否かを判断する（Ｓ１５）。例えば、充電制御回路７４は、充電終了信号が充電ステーション１２からＰＬＣ通信により送られてくると、充電を終了すると判断してもよい。 Next, when receiving a connection response in the wireless unit 15, the charging control device 11 confirms that wireless communication with the charging station 12 has been established (S14).
Next, the charging control device 11 determines whether or not the charging control circuit 74 ends the charging (S15). For example, the charging control circuit 74 may determine that charging is to be terminated when a charging end signal is sent from the charging station 12 via PLC communication.

充電を終了すると判断した場合（Ｓ１５がＹｅｓ）、充電制御装置１１は、充電制御回路７４において充電器７３を停止する（Ｓ１８）。
一方、充電を終了しないと判断した場合（Ｓ１５がＮｏ）、充電制御装置１１は、ケーブル外れ検出回路７６によりケーブル外れが検出されたか否かを判断する（Ｓ１６）。 When it is determined that the charging is to be terminated (S15 is Yes), the charging control device 11 stops the charger 73 in the charging control circuit 74 (S18).
On the other hand, when it is determined that charging is not terminated (No in S15), the charging control device 11 determines whether or not cable disconnection is detected by the cable disconnection detection circuit 76 (S16).

ケーブル外れが検出されていないと判断した場合（Ｓ１６がＮｏ）、充電制御装置１１は、Ｓ１５に戻る。
一方、ケーブル外れが検出されたと判断した場合（Ｓ１６がＹｅｓ）、充電制御装置１１は、無線ユニット１５から充電ステーション１２の無線ユニット１６に無線通信により充電中にケーブル外れが検出された旨を示すケーブル外れ検出信号、監視情報、及び車両ＩＤを送信し（Ｓ１７）、充電制御回路７４において充電器７３を停止する（Ｓ１８）。なお、監視情報としては、例えば、上述の侵入者検知信号、ユーザ不在信号、イグニッション操作信号、又は車両駆動信号などが考えられる。 When it is determined that cable disconnection is not detected (No in S16), the charging control device 11 returns to S15.
On the other hand, when it is determined that the cable disconnection is detected (Yes in S16), the charging control device 11 indicates that the cable disconnection is detected during charging from the wireless unit 15 to the wireless unit 16 of the charging station 12 by wireless communication. A cable disconnection detection signal, monitoring information, and a vehicle ID are transmitted (S17), and the charger 73 is stopped in the charging control circuit 74 (S18). As the monitoring information, for example, the intruder detection signal, the user absence signal, the ignition operation signal, or the vehicle driving signal described above can be considered.

また、充電ステーション１２は、無線ユニット１６から充電制御装置１１の無線ユニット１５に接続応答を送信した後（Ｓ１３）、送電制御回路８３において充電を終了するか否かを判断する（Ｓ１９）。例えば、送電制御回路８３は、充電制御装置１１からＰＬＣ通信により送られてくる充電状態がユーザにより設定される所望な充電状態になると、充電を終了すると判断し、充電終了信号を充電制御装置１１に送信してもよい。また、充電ステーション１２は、充電制御装置１１に供給している電力の漏電を検出した場合も、充電を終了すると判断し、充電終了信号を充電制御装置１１に送信してもよい。   The charging station 12 transmits a connection response from the wireless unit 16 to the wireless unit 15 of the charging control device 11 (S13), and then determines whether or not to end the charging in the power transmission control circuit 83 (S19). For example, the power transmission control circuit 83 determines that the charging is terminated when the charging state transmitted from the charging control device 11 through PLC communication is a desired charging state set by the user, and sends a charging end signal to the charging control device 11. May be sent to. The charging station 12 may also determine that charging is to be terminated and transmit a charging end signal to the charging control device 11 even when leakage of the power supplied to the charging control device 11 is detected.

充電を終了すると判断した場合（Ｓ１９がＹｅｓ）、充電ステーション１２は、送電制御回路８３においてリレー８２を切断する（Ｓ２２）。
一方、充電を終了しないと判断した場合（Ｓ１９がＮｏ）、充電ステーション１２は、無線ユニット１６において充電制御装置１１から送信されるケーブル外れ検出信号、監視情報、及び車両ＩＤを受信し、かつ、その車両ＩＤと無線通信の確立で使用された車両ＩＤとが一致するか否かを判断する（Ｓ２０）。 When it is determined that charging is to be terminated (S19 is Yes), the charging station 12 disconnects the relay 82 in the power transmission control circuit 83 (S22).
On the other hand, when it is determined that charging is not terminated (S19 is No), the charging station 12 receives the cable disconnection detection signal, the monitoring information, and the vehicle ID transmitted from the charging control device 11 in the wireless unit 16, and It is determined whether or not the vehicle ID matches the vehicle ID used in establishing wireless communication (S20).

ケーブル外れ検出信号、監視情報、及び車両ＩＤを受信していないと判断した場合（Ｓ２０がＮｏ）、充電ステーション１２は、Ｓ１９に戻る。
一方、ケーブル外れ検出信号、監視情報、及び車両ＩＤを受信し、かつ、その車両ＩＤと無線通信の確立で使用された車両ＩＤとが一致すると判断した場合（Ｓ２０がＹｅｓ）、充電ステーション１２は、ケーブル外れ検出信号及び監視情報に応じた処理を実行させるための信号を異常判別回路１７から認証回路８５及び警報装置１８にそれぞれ出力し（Ｓ２１）、送電制御回路８３においてリレー８２を切断する（Ｓ２２）。このとき、警報装置１８は、例えば、音声やディスプレイ表示などにより「充電中にケーブル外れが発生したこと及び車両内に侵入者がいること」をユーザに知らせる。また、認証回路８５は、例えば、車両ＩＤに基づく認証を解除する。 When it is determined that the cable disconnection detection signal, the monitoring information, and the vehicle ID are not received (No in S20), the charging station 12 returns to S19.
On the other hand, when the cable disconnection detection signal, the monitoring information, and the vehicle ID are received and it is determined that the vehicle ID matches the vehicle ID used in establishing the wireless communication (S20 is Yes), the charging station 12 Then, the cable disconnection detection signal and a signal for executing processing according to the monitoring information are output from the abnormality determination circuit 17 to the authentication circuit 85 and the alarm device 18 (S21), and the relay 82 is disconnected in the power transmission control circuit 83 (S21). S22). At this time, the alarm device 18 notifies the user that “the cable has been disconnected during charging and that there is an intruder in the vehicle”, for example, by voice or display. Moreover, the authentication circuit 85 cancels | releases the authentication based on vehicle ID, for example.

このように、第１実施形態の車両充電システム１０では、充電前に車両ＩＤを用いて無線通信を確立しておき、充電中にケーブル外れが発生すると、ケーブル外れ検出信号、監視情報、及び車両ＩＤを無線通信により充電制御装置１１から充電ステーション１２に送信する。これにより、１つの場所に複数の充電ステーション１２が設置されている環境において充電中にケーブル外れが発生しても、どの車両がどのような状態でケーブル外れが発生したかを充電ステーション１２側で判別することができる。そのため、正規のユーザに対して車両の状態を間違いなく知らせることができる。また、ケーブル外れが発生した充電ステーション１２のリレー８２を間違いなく遮断することができる。
