Description
この発明は、充電接続装置に関し、特に電動車両に充電を行なうための充電接続装置に関する。 The present invention relates to a charging connection device, and more particularly to a charging connection device for charging an electric vehicle.
電気自動車は、車両推進用モータと、それを駆動する電力を蓄積する蓄電装置とを搭載している。この蓄電装置には車両の外部の電源から充電を行なう。この際に車両と電源とを接続する充電ケーブルが用いられる。 An electric vehicle includes a vehicle propulsion motor and a power storage device that stores electric power for driving the motor. This power storage device is charged from a power source external to the vehicle. At this time, a charging cable for connecting the vehicle and the power source is used.
近年、モータとエンジンとを搭載するハイブリッド自動車にあっても、外部電源と車両とを充電ケーブルで接続し、蓄電装置に充電を可能とするいわゆるプラグインハイブリッド車が検討されている。 In recent years, so-called plug-in hybrid vehicles have been studied in which a power storage device can be charged by connecting an external power source and a vehicle with a charging cable even in a hybrid vehicle equipped with a motor and an engine.
このような充電に用いられる充電ケーブルについて特開平7−7860号公報に記載されている。 A charging cable used for such charging is described in Japanese Patent Laid-Open No. 7-7860.
電気自動車やプラグインハイブリッド車は、通常は専用電源設備と専用コネクタおよび専用充電ケーブルを介して接続される。専用電源設備は電流容量が大きく電気自動車等を急速に充電することも可能である。 An electric vehicle or a plug-in hybrid vehicle is usually connected to a dedicated power supply facility via a dedicated connector and a dedicated charging cable. The dedicated power supply equipment has a large current capacity and can rapidly charge electric vehicles and the like.
一方、電動自動車の充電が家庭用のコンセント(ウォールソケット)からできるようにすることも検討されている。家庭用のコンセントから充電できることはユーザにとって非常に便利であるが、家庭用のコンセントはその種類によって使用可能な電流値が定められている。したがって定格電流を超えない範囲内で充電を行なう必要がある。 On the other hand, it is also under consideration to make it possible to charge an electric vehicle from a household outlet (wall socket). Although it is very convenient for a user to be able to charge from a household outlet, a current value that can be used is determined by the type of household outlet. Therefore, it is necessary to perform charging within a range not exceeding the rated current.
図4は、第1検討例の充電ケーブルを示した図である。
たとえば、図4に示すように、OA機器接地箇所等に使用されるアース端子付きコンセント(たとえば、JISC8303の2極接地極付コンセント15A125V)には、その形状に合った15アンペアのプラグが一方端に設けられた充電ケーブルが使用される。充電ケーブルに設けられているコントロールボックス(CCID:Charge Cuurent Interruption Device)には15アンペアプラグに対応する上限電流値α(A)が設定されている。車両に充電ケーブルが接続されると、コントロールボックスから車両に上限電流値α(A)に対応する情報が送信される。車両に設けられた充電装置は、その情報に基づいて、充電電流を流すようにする。
FIG. 4 is a diagram illustrating a charging cable of the first study example.
For example, as shown in FIG. 4, an outlet with a ground terminal (for example, a socket with a two-pole grounding electrode 15A125V of JIS C8303) used for an OA equipment grounding location or the like has a 15-ampere plug that matches the shape at one end. The charging cable provided in is used. An upper limit current value α (A) corresponding to a 15 ampere plug is set in a control box (CCID: Charge Current Interruption Device) provided in the charging cable. When the charging cable is connected to the vehicle, information corresponding to the upper limit current value α (A) is transmitted from the control box to the vehicle. The charging device provided in the vehicle causes a charging current to flow based on the information.
図5は、第2検討例の充電ケーブルを示した図である。
たとえば、図5に示すように、エアコン設置箇所等に用いられるアース端子付大容量コンセント(JISC8323の2極接地極付コンセント20A125V)には、その形状に合った20アンペアのプラグが一方端に設けられた充電ケーブルが使用される。充電ケーブルに設けられているコントロールボックス(CCID:Charge Cuurent Interruption Device)には20アンペアプラグに対応する上限電流値β(A)が設定されている。車両に充電ケーブルが接続されると、コントロールボックスから車両に上限電流値β(A)に対応する情報が送信される。車両に設けられた充電装置は、その情報に基づいて、充電電流を流すようにする。
FIG. 5 is a diagram showing a charging cable of the second study example.
For example, as shown in FIG. 5, a large-capacity outlet with a ground terminal used in an air-conditioner installation location (a socket with a two-pole grounding electrode 20A125V of JISC8323) is provided with a 20-ampere plug at one end according to its shape. Used charging cable. An upper limit current value β (A) corresponding to a 20 ampere plug is set in a control box (CCID: Charge Current Interruption Device) provided in the charging cable. When the charging cable is connected to the vehicle, information corresponding to the upper limit current value β (A) is transmitted from the control box to the vehicle. The charging device provided in the vehicle causes a charging current to flow based on the information.
しかし、15アンペアのコンセントと20アンペアのコンセントの両方を備える家庭も考えられる。そのような家庭では、2本の充電ケーブルを準備しなければならず、利便性に劣る。 However, homes with both 15 amp outlets and 20 amp outlets are also conceivable. In such a home, two charging cables must be prepared, which is inconvenient.
また、図5のケーブルに20アンペアプラグを15アンペアプラグに変換して15アンペアコンセントに使用することも考えられるが、コントロールボックスは車両に20アンペアの上限電流値を連絡するので、15アンペアコンセントに過電流が流れてしまう可能性があり問題である。 It is also possible to convert the 20 ampere plug into a 15 ampere plug in the cable shown in FIG. 5 and use it as a 15 ampere outlet. However, since the control box informs the vehicle of the upper limit current value of 20 ampere, There is a possibility that an overcurrent flows, which is a problem.
このような定格オーバーの誤使用を避けるために、使用者に電流値を設定させることも考えられるが、確実性がない。 In order to avoid such misuse of over rating, it may be possible for the user to set a current value, but there is no certainty.
本発明の目的は、コンセントに応じた使用可能電流値を自動的に判別し安全に充電を行なえる充電接続装置を提供することである。 An object of the present invention is to provide a charging connection device that can automatically determine a usable current value according to an outlet and perform charging safely.
この発明は、要約すると、電動車両に充電を行なうための充電接続装置であって、車両に接続するための第1の接続端と、電源に接続するための第2の接続端と、第2の接続端から第1の接続端へ送電する送電経路上に設けられ、送電経路の開閉を行なうとともに、車両に送電電流の上限値の情報を送信する充電制御ユニットとを備える。第2の接続端は、電源に接続するためのプラグを含む。プラグは、電源への接続部分の形状を複数の形状から選択可能に構成される。充電制御ユニットは、接続部分としてどのような形状が選択されているかを検出し、選択された形状に対応する上限値を情報として車両に送信する。 In summary, the present invention provides a charging connection device for charging an electric vehicle, a first connection end for connection to the vehicle, a second connection end for connection to a power source, and a second connection end. And a charging control unit that opens and closes the power transmission path and transmits information on the upper limit value of the power transmission current to the vehicle. The second connection end includes a plug for connecting to a power source. The plug is configured such that the shape of the connection portion to the power source can be selected from a plurality of shapes. The charge control unit detects what shape is selected as the connection portion, and transmits an upper limit value corresponding to the selected shape to the vehicle as information.
本発明によれば、何本も充電ケーブルを用意しなくても良く、また確実にコンセントの上限電流を守ることができる。 According to the present invention, it is not necessary to prepare any number of charging cables, and the upper limit current of the outlet can be reliably protected.
本発明について以下図面を参照して詳細に説明する。なお、図中同一または相当部分には同一の符号を付してその説明は繰返さない。 The present invention will be described in detail below with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals, and description thereof will not be repeated.
図1は、本実施の形態に係る充電接続装置の一態様である充電ケーブル1の構成を示す図である。 FIG. 1 is a diagram showing a configuration of a charging cable 1 which is an aspect of the charging connection device according to the present embodiment.
図1を参照して、充電ケーブル1は、車両に設けられたインレットに接続するためのコネクタ2と、家庭用コンセントなどの外部電源に接続するためのプラグ4と、コネクタ2とプラグ4の間の充電経路上に設けられたCCID3とを含む。
Referring to FIG. 1, charging cable 1 includes a
すなわち、電動車両に充電を行なうための充電接続装置である充電ケーブル1は、車両に接続するための第1の接続端(コネクタ2)と、電源に接続するための第2の接続端(プラグ4)と、第2の接続端(プラグ4)から第1の接続端(コネクタ2)へ送電する送電経路上に設けられ、送電経路の開閉を行なうとともに、車両に送電電流の上限値の情報を送信する充電制御ユニット(CCID3)とを備える。第2の接続端は、電源に接続するためのプラグ4を含む。プラグ4は、変換アダプタ6を着脱することによって、電源への接続部分の形状を複数の形状から選択可能に構成される。充電制御ユニットは、接続部分としてどのような形状が選択されているかを検出し、選択された形状に対応する上限値を情報として車両に送信する。
That is, the charging cable 1 which is a charging connection device for charging an electric vehicle has a first connection end (connector 2) for connection to the vehicle and a second connection end (plug) for connection to a power source. 4) and information on the upper limit value of the power transmission current provided on the power transmission path for transmitting power from the second connection end (plug 4) to the first connection end (connector 2), opening and closing the power transmission path. The charging control unit (CCID3) for transmitting. The second connection end includes a
具体的には、プラグ4には、変換アダプタ6がプラグ4に装着されているか否かを検出するためのスイッチ8が設けられている。変換アダプタ6の表側6Aにはコンセント7の形状に合わせた突起9B,9C,9Dが設けられている。また変換アダプタ6の裏側6Bにはコンセント5と同様な穴に加えて、突起9Aが設けられている。
Specifically, the
変換アダプタ6をプラグ4に装着すると、変換アダプタに設けられた突起9Aがスイッチ8の穴部分に挿入される。これによりスイッチ8がオン状態となり、これがCCID3によって検出される。CCID8は、変換アダプタ6が装着されていないときは、コンセント5の定格電流(たとえば20アンペア)に対応する情報を車両に送信し、変換アダプタ6が装着されているときは、コンセント7の定格電流(たとえば15アンペア)に対応する情報を車両に送信する。
When the
これにより、車両に設けられた充電装置は、使用しているコンセントに対応する上限値を認識し、過電流を避けつつなるべく早く充電が終了するように充電を行なうことができる。 Thereby, the charging device provided in the vehicle can recognize the upper limit value corresponding to the outlet being used, and can perform charging so that charging is completed as soon as possible while avoiding overcurrent.
図2は、図1のCCID3の内部の制御装置が実行する制御を説明するためのフローチャートである。
FIG. 2 is a flowchart for explaining control executed by the control device inside
図1、図2を参照して、まず、処理が開始されると、ステップS1において、CCID3は、スイッチ8の状態を検出することによって、変換アダプタ6がプラグ4に装着されているか否かを判断する。
Referring to FIGS. 1 and 2, first, when the process is started, in step S1,
ステップS1において変換アダプタ6の装着が検出された場合にはステップS2に処理が進み、上限電流値はα(A)に設定される。ステップS1において変換アダプタ6の装着が検出されなかった場合にはステップS3に処理が進み、上限電流値はβ(A)に設定される。設定された上限電流値は、車両に送信される。
If the attachment of the
以上説明したように、本実施の形態の充電接続装置は、変換アダプターを接続した場合であっても、変換アダプタの接続を検出してCCIDの上限電流を設定することができるので、定格オーバーや過小電流による充電を防止し、変換アダプタを用いた適切な充電が可能となる。 As described above, the charging connection device of the present embodiment can detect the connection of the conversion adapter and set the upper limit current of the CCID even when the conversion adapter is connected. Charging due to an undercurrent is prevented, and appropriate charging using a conversion adapter becomes possible.
また、変換アダプタの装着の有無によって正しくコンセントにあった上限電流値がCCIDに設定される。これは人間が設定ボタンなどで上限電流値を切り替えるよりも確実に正しい値を設定できる。 Also, the upper limit current value that is correctly at the outlet depending on whether or not the conversion adapter is attached is set in CCID. This is because a human can set the correct value more reliably than switching the upper limit current value with a setting button or the like.
