Description

本発明は、電気自動車やプラグインハイブリッドカー等のコンダクティブ充電システムに用いられる充電ケーブルに関するものである。   The present invention relates to a charging cable used in a conductive charging system such as an electric vehicle or a plug-in hybrid car.

今後、急速な普及が予想される電気自動車やプラグインハイブリッドカーに搭載される車載電池の充電システムに関し、米国のＳＡＥ（ソサエティ・オブ・オートモーティブ・エンジニアズ）とＪＥＶＡ（旧日本電動車両協会：現在ＪＡＲＩ日本自動車研究所）が共同で定めた2種類の標準システム（インダクティブ充電システムまたはコンダクティブ充電システム）が存在する。これらの両システムによる充電機は、共に２００Vの電源を一旦高周波に変換して、それをトランスで昇圧し、その後整流し直流にしてバッテリを充電する点は共通しており、最大の相違点は、充電機の主要部分（高周波変換と昇圧）を地上におくか（インダクティブ充電システム）、車両に搭載するか（コンダクティブ充電システム）の差である。   Regarding the charging system for in-vehicle batteries installed in electric cars and plug-in hybrid cars that are expected to spread rapidly in the future, US SAE (Society of Automotive Engineers) and JEVA (Former Japan Electric Vehicle Association: Present There are two types of standard systems (inductive charging system or inductive charging system) jointly defined by JARI Japan Automobile Research Institute. Both of these chargers are common in that the power supply of 200V is once converted to high frequency, boosted with a transformer, and then rectified to direct current to charge the battery. The biggest difference is The difference between whether the main part of the charger (high frequency conversion and boost) is placed on the ground (inductive charging system) or mounted on the vehicle (conductive charging system).

このうち、コンダクティブ充電システムでは、すべてが車載になるため、地上側の設備は比較的簡単になるが、該地上側設備に充電ケーブル・漏電遮断手段を含めることが必要になり、通常は、ＣＣＩＤと呼ばれる漏電遮断機構を内蔵した保護装置をケーブルの途中に備えた専用の充電ケーブルが用いられる。   Of these, in the conductive charging system, since everything is mounted on the vehicle, the equipment on the ground side is relatively simple, but it is necessary to include a charging cable / leakage cutoff means in the ground side equipment. A dedicated charging cable equipped with a protective device with a built-in earth leakage interrupting mechanism called in the middle of the cable is used.

コンダクティブ充電システムの中にも、更に複数の充電モードが存在し、例えば、地上側の設備として充電ケーブル・漏電遮断手段のみが要求されるモードや（以下、モード１）、地上側の設備として充電ケーブル・漏電遮断手段に加えて電気自動車の制御部（ＥＣＵ）に送信するパイロット回路信号ＣＰＬＴを発生させるコントロールパイロット回路を含む制御手段が要求されるモード（以下、モード２）等があり、日本や欧州ではモード１仕様の充電システムを採用可能であるが、米国ではモード２仕様の充電システムが必要である等、各国ごとに異なる規格に準拠することが必要となる。   There are also several charging modes in the conductive charging system. For example, a mode in which only a charging cable / leakage breaker is required as ground side equipment (hereinafter referred to as mode 1), charging as ground side equipment. There are modes that require control means including a control pilot circuit that generates a pilot circuit signal CPLT to be transmitted to the control unit (ECU) of the electric vehicle in addition to the cable / leakage cutoff means (hereinafter referred to as mode 2). In Europe, a mode 1 specification charging system can be adopted, but in the United States, a mode 2 specification charging system is required, and it is necessary to comply with different standards in each country.

図４には、例えば、特許文献1等に記載された従来のモード２対応の充電ケーブルの構成に関する説明図を示している。モード２におけるコントロールパイロット回路に関する規格（ＳＡＥ Ｊ１７７２規格、ＪＥＶＳ Ｇ１０９規格等）では、該コントロールパイロット回路は、外部電源に接続される充電ケーブルプラグ１から３０ｃｍ以内に配置することが定められている。図４に示すように、従来、モード２対応の充電ケーブルは、車両と外部電源をつなぐ充電ケーブルの途中に、ＣＣＩＤとコントロールパイロット回路５を内蔵する筺体６を設ける構成を有し、該筺体６は、前記のＳＡＥ Ｊ１７７２規格、ＪＥＶＳ Ｇ１０９規格を満足するために、外部電源に接続される充電ケーブルプラグ１から３０ｃｍ以内に配置されていた。   FIG. 4 shows an explanatory diagram regarding the configuration of a conventional charging cable compatible with mode 2 described in, for example, Patent Document 1 and the like. In the standards relating to the control pilot circuit in mode 2 (SAE J1772 standard, JEVS G109 standard, etc.), it is stipulated that the control pilot circuit is disposed within 30 cm from the charging cable plug 1 connected to the external power source. As shown in FIG. 4, a conventional charging cable compatible with mode 2 has a configuration in which a casing 6 containing a CCID and a control pilot circuit 5 is provided in the middle of a charging cable connecting a vehicle and an external power source. In order to satisfy the SAE J1772 standard and the JEVS G109 standard, the charging cable plug 1 connected to an external power source is disposed within 30 cm.

しかし、ＣＣＩＤとコントロールパイロット回路５を内蔵する筺体６は大型化して嵩高くなり、このような大型の筺体を充電ケーブルプラグ１から３０ｃｍ以内に吊り下げて配置するため、該大型の筺体が宙に浮いた状態となって不安定であるという問題や、充電ケーブルプラグ１に該筺体の重力負荷がかかる問題があった。   However, the housing 6 containing the CCID and the control pilot circuit 5 becomes larger and bulky. Since such a large housing is hung within 30 cm from the charging cable plug 1, the large housing is suspended in the air. There are problems that the floating state is unstable and that the charging cable plug 1 is subjected to a gravity load of the casing.

また、モード２対応の充電ケーブルは、ＣＣＩＤとコントロールパイロット回路が同一の筺体に内蔵されているため、ＣＣＩＤのみが必要となるモード１対応の充電ケーブルとで、共有化が図れず、コスト高になるという問題があった。   In addition, since the CCID and the control pilot circuit are built in the same housing, the mode 2 compatible charging cable cannot be shared with the mode 1 compatible charging cable that requires only the CCID, resulting in high costs. There was a problem of becoming.

本発明に係る充電ケーブルは、自動車と接続するコネクタ部を一端に備え、外部電源と接続するプラグ部を他端に備える充電ケーブルであって、該プラグ部は、漏電検出手段と、外部電源から自動車への電路を開閉する電路開閉リレーと、漏電検出手段からの漏電検出信号を受けて該電路開閉リレーの開閉制御を行うリレー制御回路と、回路動作用の交流・直流変換の制御用電源と、自動車側の充電制御信号を該リレー制御回路に伝える外部信号接続部を備える構成を有し、該外部信号接続部に、前記自動車側の制御部に送信する制御信号を発生させる回路を含む充電制御部を追加接続可能な構成としている。外部電源と接続するプラグ部自体を当該構成とすることにより、従来は、充電ケーブルプラグから吊り下げ配置される大型の筺体内に設けていたＣＣＩＤ内蔵の保護装置が不要となる。すなわち、モード１対応の場合には、該プラグ部とケーブルと自動車との接続コネクタのみから構成される充電ケーブルを実現することができ、また、モード２対応の場合には、コントロールパイロット回路のみを内蔵した小型の筺体を、該プラグ部に接続した充電ケーブルを実現することができ、いずれの場合であっても、従来の大型の筺体に由来した問題（大型の筺体を充電ケーブルプラグから３０ｃｍ以内に吊り下げて配置するため、該大型の筺体が宙に浮いた状態となって不安定であるという問題や、充電ケーブルプラグ１に該筺体の重力負荷がかかる問題）を解消することができる。 The charging cable according to the present invention is a charging cable provided with a connector portion connected to an automobile at one end and a plug portion connected to an external power source at the other end, and the plug portion is connected to a leakage detecting means and an external power source. An electric circuit switching relay that opens and closes an electric circuit to the automobile, a relay control circuit that performs open / close control of the electric circuit switching relay in response to a leakage detection signal from a leakage detection means, and a power supply for control of AC / DC conversion for circuit operation; A charging circuit including an external signal connection unit that transmits a charging control signal on the vehicle side to the relay control circuit, and a circuit that generates a control signal to be transmitted to the control unit on the vehicle side in the external signal connection unit. The control unit can be additionally connected . By adopting the plug portion itself connected to the external power supply in this configuration, a CCID built-in protection device that is conventionally provided in a large casing suspended from the charging cable plug becomes unnecessary. That is, in the case of mode 1, it is possible to realize a charging cable composed only of the plug portion, the cable, and the connection connector of the automobile. It is possible to realize a charging cable in which a small built-in housing is connected to the plug portion, and in any case, a problem derived from a conventional large housing (the large housing is within 30 cm from the charging cable plug. Therefore, it is possible to solve the problem that the large casing is unstable because it is suspended in the air, and the problem that the gravitational load of the casing is applied to the charging cable plug 1).

また、外部電源と接続するプラグ部自体を当該構成としたことにより、例えば、コンダクティブ充電システムの中で、地上側の設備として充電ケーブル・漏電遮断手段のみが要求されるモード（モード１）の場合には、当該プラグ部を単独で使用し、地上側の設備として充電ケーブル・漏電遮断手段に加えて電気自動車の制御部（ＥＣＵ）に送信するパイロット回路信号ＣＰＬＴを発生させるコントロールパイロット回路を含む制御手段が要求されるモード（モード２）の場合には、当該プラグ部に、充電制御部を追加接続して使用すればよく、該プラグ部は各種モードに汎用することができるため、部品の共有化が可能となる。これにより、従来各種モードごとに、専用部品を用いていた場合に比べて、製造プロセスの効率化が図られ、製品管理コストや製造コストを低下させることができる。   In addition, since the plug unit itself connected to the external power source is configured as described above, for example, in a mode (mode 1) in which only a charging cable / leakage interrupting means is required as ground-side equipment in a conductive charging system. Includes a control pilot circuit that uses the plug unit alone and generates a pilot circuit signal CPLT to be transmitted to the control unit (ECU) of the electric vehicle in addition to the charging cable / leakage interrupting means as ground-side equipment. In the mode (mode 2) in which the means is required, a charging control unit may be additionally connected to the plug unit, and the plug unit can be used for various modes. Can be realized. Thereby, the efficiency of the manufacturing process can be improved and the product management cost and the manufacturing cost can be reduced as compared with the case where dedicated parts are used for each of the various conventional modes.

That is, according to the present invention, since only the control pilot circuit needs to be accommodated in the housing suspended from the plug portion 1, the housing suspended from the plug portion 1 can be reduced in size. In the present invention, the charging control unit can be additionally connected as necessary by providing an external signal connection unit that transmits the charging control signal on the automobile side to the relay control circuit.

自動車への通電を開始するためには、リレー制御回路１５が電路開閉リレー１４を閉じる制御を行うことが前提となる。リレー制御回路１５が電路開閉リレー１４を閉じる制御を行う手段として、例えば、リレー制御回路１５が、コネクタ部３が自動車と接続した状態を検出するコネクタ部接続信号（図示省略）と、プラグ部１が外部電源と接続した状態を検出するプラグ部接続信号（図示省略）を、合わせて受けたとき、電路を閉じて充電を開始する方法（以下、方法Ａ）がある。この場合、コネクタ部接続信号を作成する回路をプラグ部１の内部に設けたり、リレー制御回路１５の内部に設けることとなるが、充電制御部２を接続したものでは、コントロールパイロット回路がコネクタ部接続信号を作成することとなる。   In order to start energization of the automobile, it is assumed that the relay control circuit 15 performs control to close the electric circuit switching relay 14.

When a signal (not shown) is received, means for opening the electric circuit opening / closing relay 14 and stopping charging can be used in combination.

なお、充電開始操作スイッチや充電開始選択手段２２がなく、リレー制御回路１５が外部へ信号を出力する必要がないときには、外部信号端子は入力専用のものとなる。   When there is no charge start operation switch or charge start selection means 22 and the relay control circuit 15 does not need to output a signal to the outside, the external signal terminal is dedicated for input.

前記の実施形態１では、コンダクティブ充電システムのうち、地上側の設備として充電ケーブル・漏電遮断手段に加えて電気自動車の制御部（ＥＣＵ）に送信するパイロット回路信号ＣＰＬＴを発生させるコントロールパイロット回路を含む制御手段が要求されるモード（モード２）に対応した充電ケーブルを説明したが、充電制御部２を接続しない状態で該プラグ部１を用いて、コンダクティブ充電システムのモード１に対応した充電ケーブルとすることもできる。   The first embodiment includes a control pilot circuit that generates a pilot circuit signal CPLT to be transmitted to a control unit (ECU) of an electric vehicle in addition to a charging cable / leakage interrupting means as an equipment on the ground side in the conductive charging system. Although the charging cable corresponding to the mode (mode 2) in which the control means is required has been described, a charging cable corresponding to mode 1 of the conductive charging system can be obtained using the plug unit 1 in a state where the charging control unit 2 is not connected. You can also

なお、モード１対応の場合には、該プラグ部１とケーブル７と自動車との接続に用いるコネクタ部３のみから構成される充電ケーブルとすればよく、また、モード２対応の場合には、コントロールパイロット回路のみを内蔵した小型の筺体を、該プラグ部に接続した充電ケーブルとすればよく、いずれの場合であっても、該プラグ部１を汎用することができるため、部品の共有化が可能となる。これにより、従来各種モードごとに、専用部品を用いていた場合に比べて、製造プロセスの効率化が図られ、製品管理コストや製造コストを低下させることができる。   In the case of mode 1 compatibility, a charging cable composed only of the connector section 3 used for connecting the plug section 1, the cable 7 and the automobile may be used. A small housing containing only a pilot circuit may be used as a charging cable connected to the plug portion. In any case, the plug portion 1 can be used for general purposes, so that parts can be shared. It becomes. Thereby, the efficiency of the manufacturing process can be improved and the product management cost and the manufacturing cost can be reduced as compared with the case where dedicated parts are used for each of the various conventional modes.
