Description

一般の人が、高電圧大電流の自動車用充電器を使用するに際し、コネクターに対し悪戯されず、不注意でコネクターを放置することを防止する安全性を高めた自動車用充電器に関するものである。   The present invention relates to an automobile charger with improved safety that prevents a general person from inadvertently leaving the connector inadvertently when using a high-voltage, high-current automobile charger. .

電気自動車用急速充電器は、数十キロワットの出力を持ち、直流で数百アンペア、数百ボルトが流れる普通の家電ではない電気機器であり、一般人が扱うものであるためその安全性を大いに高めておく必要がある。とくに、電気自動車に接合されるコネクターは、電極がむき出しであり、そこへの悪戯または破壊行為は、生命にもかかわる重大な結果を及ぼす恐れがある。   Fast chargers for electric vehicles have an output of several tens of kilowatts, and are electric devices that are not ordinary home appliances that flow hundreds of amperes and hundreds of volts in direct current. It is necessary to keep. In particular, connectors that are joined to electric vehicles have exposed electrodes, and mischief or destruction of them can have serious life-threatening consequences.

しかし、現状の充電器にはそのような配慮がなされていない。特に充電中に充電器から離れる場合のコネクター収納箱への悪戯、また、充電した後のコネクターの放置などは安全性に大きな影響がある。   However, such a consideration is not made in the current charger. In particular, mischief of the connector storage box when leaving the charger during charging, and leaving the connector after charging have a significant impact on safety.

本発明が解決しようとする問題点は、電気自動車用充電器の、特に使用者に近いコネクターの安全性を高めることである。   The problem to be solved by the present invention is to increase the safety of an electric vehicle charger, particularly a connector close to the user.

本発明では、コネクターを通常収容しているコネクターボックスに、収納用のセンサーつきコネクターソケットを設けコネクターボックスの扉にはコネクターソケットにコネクターが挿入しているときのみに認証によって開錠する電磁ロックを設ける。   In the present invention, a connector socket with a sensor for storage is provided in a connector box that normally accommodates a connector, and an electromagnetic lock that is unlocked by authentication only when the connector is inserted into the connector socket on the connector box door. Provide.

操作者が現場を離れるときは常にコネクターボックスは閉まっており、コネクターに対する悪戯を防止し、充電完了後には必ず操作者がコネクターをコネクターボックスに収納して電磁ロックをかけることによりコネクターの放置を防止する。   Whenever the operator leaves the site, the connector box is closed to prevent mischief against the connector, and after charging is complete, the operator must store the connector in the connector box and lock the electromagnetic lock to prevent the connector from being left unattended. To do.

コネクターボックスの中にセンサー付きコネクターソケットと、それと連動してコネクターボックスの扉に電磁ロックをつけることにより高い安全性を実現した。また必要な行為を促すように音声ガイドやランプにより一般利用者にもできるようにした。   A connector socket with a sensor in the connector box and an electromagnetic lock on the connector box door in conjunction with the sensor socket ensure high safety. In addition, general users can use voice guidance and lamps to encourage necessary actions.

電気自動車の充電をしようとする時、認証用非接触カードを認識情報を読み取るカードセンサーに近づけて前記認証用非接触カードに記憶された認識情報を前記カードセンサーから受信して読み込む。認証データは充電器の中にあるメモリーを参照して認証するか、またはカードセンサーに接続されているネットワークを通して、管理サーバ９に送られ、サーバ９で認証される。 When charging the electric vehicle, the authentication contactless card is brought close to the card sensor that reads the recognition information, and the recognition information stored in the authentication contactless card is received from the card sensor and read. The authentication data is authenticated by referring to a memory in the charger, or sent to the management server 9 through a network connected to the card sensor and authenticated by the server 9.

認証された場合、認証された事実が通信基板に送られ、開錠信号がコネクター２が収められているコネクターボックス３の扉の電磁ロック５に送られる。後で述べるが、この電磁ロック５はコネクター２がコネクターボックス３のコネクターソケット４に収められている時だけロックすることができる電磁ロックである。   If authenticated, the authenticated fact is sent to the communication board, and an unlocking signal is sent to the electromagnetic lock 5 on the door of the connector box 3 in which the connector 2 is housed. As will be described later, the electromagnetic lock 5 is an electromagnetic lock that can be locked only when the connector 2 is housed in the connector socket 4 of the connector box 3.

開錠信号が電磁ロック５をアンロックすると、操作者はコネクター２をコネクターボックス３のソケット４から外し、電気自動車に結合する。すると、音声、充電器のディスプレー、またはランプにより、前記扉を閉めるように促す。扉を閉めることを促すのは、操作者が充電中に充電器から離れる場合に、第３者がコネクターボックス３に悪戯することを防止するためである。このとき、電磁ロック５は、コネクター２がコネクターソケット４に外れている場合はロック状態となることができる。ソケット４からコネクター２が外されたということは、ソケット４の中にあるセンサーによって感知されてもよいし、コネクター２の中にある通信用ケーブルが、接続状態でなくなるので、充電器の本体でコネクター２がソケット４から乖離したことを感知してもよい。
コネクター２がソケット４から外れないうちに電磁ロック５がかからないようにするのは、勿論コネクター２が取り出せなくなる事を防止するためである。 When the unlocking signal unlocks the electromagnetic lock 5, the operator disconnects the connector 2 from the socket 4 of the connector box 3 and couples it to the electric vehicle. Then, it is urged to close the door by voice, a charger display, or a lamp. The reason for prompting the user to close the door is to prevent a third person from mischiefing the connector box 3 when the operator leaves the charger during charging. At this time, the electromagnetic lock 5 can be locked when the connector 2 is detached from the connector socket 4. The fact that the connector 2 is disconnected from the socket 4 may be detected by a sensor in the socket 4, and the communication cable in the connector 2 is not connected. It may be detected that the connector 2 is separated from the socket 4.
The reason why the electromagnetic lock 5 is not applied before the connector 2 is removed from the socket 4 is to prevent the connector 2 from being taken out.

電磁ロック５がロック状態であるとのデータを前記通信基板１に送ると、急速充電器は充電待機状態になる。すると、操作者は充電スタートボタンを押して、充電が始まる。充電に１０分ぐらいはかかるので操作者は充電器を離れる可能性が高い。しかしコネクター２は自動車に挿入されているし、充電器のコネクターボックスは扉が閉まってロックされているので安全性は確保されている。充電が始まると車止め７が上がって、自動車が充電器から離脱できないようにしてもよい。   When data indicating that the electromagnetic lock 5 is in the locked state is sent to the communication board 1, the quick charger enters a charging standby state. Then, the operator presses the charge start button to start charging. Since charging takes about 10 minutes, the operator is likely to leave the charger. However, the connector 2 is inserted in the automobile, and the connector box of the charger is locked with the door closed, so that safety is ensured. When charging is started, the car stop 7 may be raised so that the automobile cannot be detached from the charger.

充電器の停止ボタンが押されるか、充分充電されて充電が終了すると、使用電力量が前記通信基板１におくられ、サーバー９に送られ課金処理が進んだり、カードリーダーに送られ電子マネーの決済を待つことになる。充電が終了したことは充電器のディスプレーに表示されたり、充電器についているランプにより操作者に次の終了作業の行動を促す。   When the stop button of the charger is pressed or when the battery is fully charged and charging is completed, the amount of power used is placed on the communication board 1 and sent to the server 9 for billing processing or sent to a card reader to send electronic money. Wait for payment. The completion of charging is displayed on the display of the charger, or the operator prompts the operator to perform the next end work by a lamp attached to the charger.

終了作業の開始として、操作者は前記認証用カードを再度カードリーダーに近接させると、カードリーダーはカードのデータを読み込み、データが前記通信基板１に送られ、前記認証データと同一かどうかを判断し、カードが電子決済の場合は決済が行われる。操作者が同一の場合は、前記通信基板１は前記電磁ロック５に開錠信号を送る。開錠信号を受信すると前記電磁ロック５がアンロックし、音声、ディスプレー表示、ランプによりコネクター２をコネクターボックス３の中のソケット４に戻すように操作者に促す。   As the start of the end work, when the operator brings the authentication card close to the card reader again, the card reader reads the card data, and the data is sent to the communication board 1 to determine whether it is the same as the authentication data. If the card is electronic payment, payment is made. When the operator is the same, the communication board 1 sends an unlock signal to the electromagnetic lock 5. When the unlocking signal is received, the electromagnetic lock 5 is unlocked and prompts the operator to return the connector 2 to the socket 4 in the connector box 3 by voice, display display, or lamp.

前記コネクター２が前記ソケット４に戻された場合において、前記コネクター２が前記ソケット４に適切に戻されたことを確認するソケットセンサーまたは、前述のごとくコネクター２の中の通信線がコネクター２の通信線が通電したことを充電器本体が感知しその嵌合信号を電磁ロック５に送信する。   When the connector 2 is returned to the socket 4, a socket sensor for confirming that the connector 2 is properly returned to the socket 4 or a communication line in the connector 2 as described above is a communication of the connector 2. The charger body senses that the line is energized and transmits a fitting signal to the electromagnetic lock 5.

すると、音声、充電器ディスプレー、またはランプにより、コネクターボックス扉６を閉じるように操作者に促す。前記電磁ロック５は、前記ソケット４にコネクター２が戻った後にロック可能となる。   Then, the operator is prompted to close the connector box door 6 by voice, a charger display, or a lamp. The electromagnetic lock 5 can be locked after the connector 2 is returned to the socket 4.

電磁ロック５がロックされると、電磁ロック信号が前記通信基板１に送られ、通信基板１が車止め７の駆動装置に車止めを下げるように指示して、車は充電器から離脱することができる。   When the electromagnetic lock 5 is locked, an electromagnetic lock signal is sent to the communication board 1, and the communication board 1 instructs the driving device of the car stop 7 to lower the car stop, so that the car can be detached from the charger. .

コネクターボックスの中のコネクターソケットと、扉に電磁ロックを設け、さらに制御可能な車止めを設けることにより、安全な電気自動車用充電器とすることができる。   By providing an electromagnetic lock on the connector socket in the connector box and the door and further providing a controllable vehicle stop, a safe charger for an electric vehicle can be obtained.
