Description

車両用電力変換装置Power converter for vehicle
　本発明は、電動車両用の車両用電力変換装置に関する。 The present invention relates to a vehicle power conversion device for an electric vehicle.
　近年、ガソリンをエネルギー源として走行するガソリン車だけではなく、環境に優しい電気をエネルギー源として走行する電気自動車（ＥＶ：Ｅｌｅｃｔｒｉｃ　Ｖｅｈｉｃｌｅ）、ガソリンと電気をエネルギー源として走行するプラグインハイブリッド自動車（ＰＨＥＶ：Ｐｌｕｇ－ｉｎ　Ｈｙｂｒｉｄ　Ｅｌｅｃｔｒｉｃ　Ｖｅｈｉｃｌｅ）および水素をエネルギー源として走行する燃料電池車（ＦＣＶ：Ｆｕｅｌ　Ｃｅｌｌ　Ｖｅｈｉｃｌｅ）などのエコカーが普及してきている。また、上記エコカーの普及により車両の駆動用蓄電池の電力を宅内負荷に利用するＶ２Ｈ（Ｖｅｈｉｃｌｅ　ｔｏ　Ｈｏｍｅ）システムも普及しつつある。 In recent years, not only gasoline vehicles that run on gasoline as an energy source, but also electric vehicles (EV) that run on environment-friendly electricity, and plug-in hybrid vehicles (PHEV) that run on gasoline and electricity as energy sources. Eco-cars such as Plug-in Hybrid Electric Vehicle (FCV) and fuel cell vehicles (FCV: Fuel Cell Vehicle) that run on hydrogen as an energy source are becoming popular. In addition, with the spread of the eco-car, a V2H (Vehicle to Home) system that uses electric power of a vehicle storage battery for a home load is also becoming widespread.
　Ｖ２Ｈシステムにおいて、電動車両へ車両用電力変換装置から充電する場合または電動車両から車両用電力変換装置を経由して宅内負荷に電力を給電する場合には、充電ケーブルを接続する必要がある。しかし、充電ケーブルの接続に関しては、安全面で多くの懸念事項が考えられる。 In the V2H system, it is necessary to connect a charging cable when charging an electric vehicle from the vehicle power conversion device or when supplying electric power from the electric vehicle to the home load via the vehicle power conversion device. However, there are many safety concerns regarding the connection of the charging cable.
　例えば、充電ケーブルを電動車両に接続していることを忘れて電動車両を走行させた場合または接続された充電ケーブルにユーザーがぶら下がったり躓いたりした場合、充電ケーブルにテンションが掛かってしまい、充電ケーブル、車両用電力変換装置または電動車両を破損または故障させることが考えられる。 For example, if you forget that the charging cable is connected to the electric vehicle and run the electric vehicle, or if the user hangs or crawls the connected charging cable, the charging cable will be tensioned and the charging cable It is conceivable that the vehicle power converter or the electric vehicle is damaged or failed.
　また、電動車両の急な走行が必要となったときといった緊急時に、充電ケーブルの車両接続ロック解除機能が故障して電動車両から充電ケーブルの取り外しができなくなった場合に、電動車両の走行が不可能になるといった問題が考えられる。 Also, in the event of an emergency such as when an electric vehicle needs to run suddenly, if the vehicle connection lock release function of the charging cable fails and the charging cable cannot be removed from the electric vehicle, the electric vehicle will not run.

実施の形態１．
　図１は、本発明の実施の形態１にかかる車両用電力変換装置２と車両６との接続の様子を示す図である。系統１は、分電盤を有する車両用電力変換装置２に接続され、車両用電力変換装置２に電力を供給している。宅内負荷７は、車両用電力変換装置２に接続され、車両用電力変換装置２を経由して電力の供給を受けている。 Embodiment 1 FIG.
FIG. 1 is a diagram illustrating a state of connection between the vehicle power converter 2 and the vehicle 6 according to the first embodiment of the present invention. The system 1 is connected to a vehicle power conversion device 2 having a distribution board, and supplies power to the vehicle power conversion device 2. The in-home load 7 is connected to the vehicle power conversion device 2 and is supplied with power via the vehicle power conversion device 2.
　車両用電力変換装置２は、車両６に出力電力を供給するまたは車両６からの入力電力の供給を受けるための充電ケーブル８を備える。充電ケーブル８は、充電ケーブル８を２つの部分に離脱させることが可能となる離脱機能を有する離脱部３を有しており、充電ケーブル８の先端には、車両６と接続する為の充電プラグ４が設けられている。より詳細には、充電ケーブル８は、第一の充電ケーブル８ａおよび第二の充電ケーブル８ｂから構成され、離脱部３は、第一の離脱部である離脱部凸側３ａおよび第二の離脱部である離脱部凹側３ｂから構成されている。離脱部凸側３ａおよび離脱部凹側３ｂは互いに結合または離脱が可能である。そして、第一の充電ケーブル８ａは車両用電力変換装置２の本体および離脱部凸側３ａに接続されており、第二の充電ケーブル８ｂは離脱部凹側３ｂおよび充電プラグ４に接続されている。なお、図１では、第一の充電ケーブル８ａに凸型形状の離脱部凸側３ａが接続され、第二の充電ケーブル８ｂに凹型形状の離脱部凹側３ｂが接続されているとして示してあるが、第一の充電ケーブル８ａに凹型形状の離脱部が接続され、第二の充電ケーブル８ｂに凸型形状の離脱部が接続される構成であってもかまわない。 The vehicle power conversion device 2 includes a charging cable 8 for supplying output power to the vehicle 6 or receiving supply of input power from the vehicle 6. The charging cable 8 has a detaching part 3 having a detaching function that enables the charging cable 8 to be detached into two parts, and a charging plug for connecting to the vehicle 6 is provided at the tip of the charging cable 8. 4 is provided. More specifically, the charging cable 8 includes a first charging cable 8a and a second charging cable 8b, and the detaching portion 3 includes a detaching portion convex side 3a and a second detaching portion which are first detaching portions. It is comprised from the detachment part concave side 3b which is. The detachable portion convex side 3a and the detachable portion concave side 3b can be coupled or detached from each other. The first charging cable 8 a is connected to the main body of the vehicle power converter 2 and the detachable portion convex side 3 a, and the second charging cable 8 b is connected to the detachable portion concave side 3 b and the charging plug 4. . In FIG. 1, the first charging cable 8 a is connected to the convex-shaped detachable portion convex side 3 a and the second charging cable 8 b is connected to the concave-shaped detachable portion concave side 3 b. However, a configuration in which a concave-shaped detachment portion is connected to the first charging cable 8a and a convex-shaped detachment portion is connected to the second charging cable 8b may be employed.
　そして、車両６は、充電プラグ４を挿入する為の車両側コネクタ５を有しており、充電ケーブル８を通して車両用電力変換装置２から電力の供給を受けることが可能であるとともに、車両用電力変換装置２に電力を供給することも可能である。 The vehicle 6 has a vehicle-side connector 5 for inserting the charging plug 4. The vehicle 6 can receive power from the vehicle power conversion device 2 through the charging cable 8, and can also receive vehicle power. It is also possible to supply power to the conversion device 2.
　また、車両用電力変換装置２には、車両用電力変換装置２を制御するユーザーコントローラ９が接続されている。ユーザーコントローラ９は、車両用電力変換装置２の操作部となるリモートコントローラであり、車両用電力変換装置２との接続は有線または無線のいずれの方法であってもかまわない。ユーザーコントローラ９を介して、車両用電力変換装置２から車両６に電力を供給する、車両用電力変換装置２が車両６から電力を供給される、後述する充放電器２２に充電させるまたは充放電器２２に放電させるといった機能設定をユーザーが行うことができる。ユーザーコントローラ９は、車両用電力変換装置２の上記機能設定、充電時または放電時の電力量といった各電力量を表示する表示部９０を備えている。ユーザーは、表示部９０により充電ケーブル８の離脱の有無の監視をすることができ、充電ケーブル８の状態を確認することが可能である。 Further, a user controller 9 for controlling the vehicle power conversion device 2 is connected to the vehicle power conversion device 2. The user controller 9 is a remote controller serving as an operation unit of the vehicle power conversion device 2, and the connection with the vehicle power conversion device 2 may be either wired or wireless. Power is supplied from the vehicle power converter 2 to the vehicle 6 via the user controller 9, and the vehicle power converter 2 is supplied with power from the vehicle 6. The user can make a function setting such as discharging the electric device 22. The user controller 9 includes a display unit 90 that displays each power amount such as the above-described function setting of the vehicle power conversion device 2 and the power amount during charging or discharging. The user can monitor whether or not the charging cable 8 has been detached from the display unit 90 and can check the state of the charging cable 8.
　ここで、例えば車両用電力変換装置２から車両６に充電を行っている際に、充電ケーブル８が車両６に接続されていることをユーザーが忘れて、ユーザーが車両６を移動させた場合または接続された充電ケーブル８にユーザーがぶらさがったり躓いたりした場合に、充電ケーブル８に掛かるテンションの強さに基づいて充電ケーブル８の離脱部３が離脱する。これにより、充電ケーブル８、車両用電力変換装置２または車両６の故障を防ぐことができる。 Here, for example, when charging the vehicle 6 from the vehicle power conversion device 2, when the user forgets that the charging cable 8 is connected to the vehicle 6 and the user moves the vehicle 6, or When the user hangs or crawls on the connected charging cable 8, the detaching portion 3 of the charging cable 8 is released based on the strength of the tension applied to the charging cable 8. Thereby, the failure of the charging cable 8, the vehicle power converter 2 or the vehicle 6 can be prevented.
　図２は、実施の形態１にかかる車両用電力変換装置２内および車両６内の等価回路の一例を示すブロック図である。系統１および宅内負荷７は、車両用電力変換装置２内に設けられた分電盤２１に接続されており、分電盤２１を経由して電力のやりとりを実施している。分電盤２１は、車両用電力変換装置２内に設けられた充放電器２２に接続されている。 FIG. 2 is a block diagram illustrating an example of an equivalent circuit in the vehicle power converter 2 and the vehicle 6 according to the first embodiment. The grid 1 and the home load 7 are connected to a distribution board 21 provided in the vehicular power conversion apparatus 2, and exchange electric power via the distribution board 21. The distribution board 21 is connected to a charger / discharger 22 provided in the vehicle power converter 2.
　充放電器２２は、車両用電力変換装置２内に設けられた電気的動作スイッチ２８を介して充電ケーブル８に接続される。具体的には、充電ケーブル８が直流電源正極ケーブル２９および直流電源負極ケーブル３０を有しており、充放電器２２、直流電源正極ケーブル２９および直流電源負極ケーブル３０は電気的動作スイッチ２８に接続されている。そして、充放電器２２と直流電源正極ケーブル２９および直流電源負極ケーブル３０との電気的接続が電気的動作スイッチ２８によって切り替えられる。電気的動作スイッチ２８は、例えばＤＣパワーリレーである。 The charger / discharger 22 is connected to the charging cable 8 via an electrical operation switch 28 provided in the vehicular power converter 2. Specifically, the charging cable 8 includes a DC power supply positive cable 29 and a DC power supply negative cable 30, and the charger / discharger 22, the DC power supply positive cable 29, and the DC power supply negative cable 30 are connected to the electrical operation switch 28. Has been. The electrical connection between the charger / discharger 22 and the DC power supply positive cable 29 and the DC power supply negative cable 30 is switched by the electrical operation switch 28. The electrical operation switch 28 is, for example, a DC power relay.
　充放電器２２が系統１からの交流電力を直流電力に変換して蓄えた充電電力は、電気的動作スイッチ２８および充電ケーブル８を介して車両６へ出力電力として供給される。電気的動作スイッチ２８は、制御部である制御回路２４により制御される。具体的には、車両用電力変換装置２には、電気的動作スイッチ駆動用電源５０および電気的動作スイッチ駆動用電源５０から電気的動作スイッチ２８への接続を切替える電気的動作スイッチ２７が設けられており、制御回路２４からの信号により電気的動作スイッチ２７を動作（ＯＮ）させるまたは解列（ＯＦＦ）させることができる。 The charging power that the charger / discharger 22 has converted and stored AC power from the system 1 into DC power is supplied as output power to the vehicle 6 via the electrical operation switch 28 and the charging cable 8. The electrical operation switch 28 is controlled by a control circuit 24 which is a control unit. Specifically, the vehicle power conversion device 2 is provided with an electric operation switch driving power source 50 and an electric operation switch 27 that switches connection from the electric operation switch driving power source 50 to the electric operation switch 28. The electrical operation switch 27 can be operated (ON) or disconnected (OFF) by a signal from the control circuit 24.
　制御回路２４が電気的動作スイッチ２７を動作（ＯＮ）させると、電気的動作スイッチ駆動用電源５０からの電力が供給されて電気的動作スイッチ２８が動作（ＯＮ）して、充放電器２２が充電ケーブル８に電気的に接続される。制御回路２４が電気的動作スイッチ２７を解列（ＯＦＦ）させると、電気的動作スイッチ駆動用電源５０から電気的動作スイッチ２８への電力の供給が停止されて電気的動作スイッチ２８が解列（ＯＦＦ）して、充放電器２２と充電ケーブル８とが電気的に遮断される。 When the control circuit 24 operates (ON) the electrical operation switch 27, electric power is supplied from the electrical operation switch drive power supply 50, the electrical operation switch 28 operates (ON), and the charger / discharger 22 is activated. It is electrically connected to the charging cable 8. When the control circuit 24 disconnects the electrical operation switch 27 (OFF), the supply of power from the electrical operation switch drive power supply 50 to the electrical operation switch 28 is stopped, and the electrical operation switch 28 is disconnected ( OFF) and the charger / discharger 22 and the charging cable 8 are electrically disconnected.
　また、車両６には、車両コンタクタ５２および駆動用蓄電池５３が設けられている。駆動用蓄電池５３は、車両コンタクタ５２を介して充電ケーブル８に接続される。具体的には、駆動用蓄電池５３、直流電源正極ケーブル２９および直流電源負極ケーブル３０は車両コンタクタ５２に接続されている。そして、駆動用蓄電池５３と直流電源正極ケーブル２９および直流電源負極ケーブル３０との電気的接続が車両コンタクタ５２によって切り替えられる。 Further, the vehicle 6 is provided with a vehicle contactor 52 and a drive storage battery 53. The drive storage battery 53 is connected to the charging cable 8 via the vehicle contactor 52. Specifically, the drive storage battery 53, the DC power supply positive cable 29 and the DC power supply negative cable 30 are connected to the vehicle contactor 52. The electrical connection between the drive storage battery 53 and the DC power supply positive cable 29 and the DC power supply negative cable 30 is switched by the vehicle contactor 52.
　なお、駆動用蓄電池５３に充電された電力を放電して宅内負荷７に供給する場合は、駆動用蓄電池５３から充電ケーブル８および電気的動作スイッチ２８を経由して供給された直流電力が充放電器２２で交流電力に変換されて宅内負荷７に供給される。したがって、電気的動作スイッチ２８が解列（ＯＦＦ）することにより、車両用電力変換装置２から車両６に供給される出力電力および車両６から供給される入力電力が遮断される。 When the power charged in the drive storage battery 53 is discharged and supplied to the home load 7, the DC power supplied from the drive storage battery 53 via the charging cable 8 and the electrical operation switch 28 is charged / discharged. It is converted into AC power by the electric appliance 22 and supplied to the home load 7. Therefore, when the electrical operation switch 28 is disconnected (OFF), the output power supplied from the vehicle power converter 2 to the vehicle 6 and the input power supplied from the vehicle 6 are cut off.
　ここで、車両コンタクタ５２も、電気的動作スイッチ２８と同様に制御回路２４により制御される。具体的には、充電ケーブル８は車両コンタクタ駆動電源ケーブル３１を有しており、車両コンタクタ駆動電源ケーブル３１は、車両コンタクタ５２に接続される。車両用電力変換装置２には、電気的動作スイッチ駆動用電源５０から車両コンタクタ駆動電源ケーブル３１への接続を切替える電気的動作スイッチ２６が設けられている。そして、制御回路２４からの信号により電気的動作スイッチ２６を動作（ＯＮ）させるまたは解列（ＯＦＦ）させることができる。 Here, the vehicle contactor 52 is also controlled by the control circuit 24 in the same manner as the electrical operation switch 28. Specifically, the charging cable 8 has a vehicle contactor drive power cable 31, and the vehicle contactor drive power cable 31 is connected to the vehicle contactor 52. The vehicle power converter 2 is provided with an electrical operation switch 26 for switching the connection from the electrical operation switch drive power supply 50 to the vehicle contactor drive power cable 31. The electrical operation switch 26 can be operated (ON) or disconnected (OFF) by a signal from the control circuit 24.
　制御回路２４が電気的動作スイッチ２６を動作（ＯＮ）させると、電気的動作スイッチ駆動用電源５０からの電力が供給されて車両コンタクタ５２が動作（ＯＮ）して、車両６内に設けられた駆動用蓄電池５３が充電ケーブル８に電気的に接続される。制御回路２４が電気的動作スイッチ２６を解列（ＯＦＦ）させると、電気的動作スイッチ駆動用電源５０から車両コンタクタ５２への電力の供給が停止されて車両コンタクタ５２が解列（ＯＦＦ）して、駆動用蓄電池５３と充電ケーブル８とが電気的に遮断される。 When the control circuit 24 operates (ON) the electrical operation switch 26, power is supplied from the electrical operation switch driving power source 50, and the vehicle contactor 52 operates (ON), and is provided in the vehicle 6. A drive storage battery 53 is electrically connected to the charging cable 8. When the control circuit 24 disconnects the electrical operation switch 26 (OFF), the power supply from the electrical operation switch drive power supply 50 to the vehicle contactor 52 is stopped, and the vehicle contactor 52 is disconnected (OFF). The drive storage battery 53 and the charging cable 8 are electrically disconnected.
　車両用電力変換装置２を制御するユーザーコントローラ９は、制御回路２４に接続され、車両用電力変換装置２の機能設定を実施することができる。また、ユーザーコントローラ９は、上述したように各電力量を表示する機能を有している。ユーザーコントローラ９は、例えば、液晶パネル等で構成されたタッチパネルを備えて、タッチパネルが受け付けた入力データを制御回路２４に送出するように構成することができる。また、ユーザーコントローラ９と制御回路２４とをＬＡＮ（Ｌｏｃａｌ　Ａｒｅａ　Ｎｅｔｗｏｒｋ）またはＷｉ－Ｆｉ（登録商標）により接続できるように構成することにより、ユーザーコントローラ９としてパーソナルコンピュータ、スマートホンまたはタブレット等を用いることも可能である。 The user controller 9 that controls the vehicular power conversion device 2 is connected to the control circuit 24 and can perform function settings of the vehicular power conversion device 2. Further, the user controller 9 has a function of displaying each power amount as described above. For example, the user controller 9 may be configured to include a touch panel configured with a liquid crystal panel or the like and send input data received by the touch panel to the control circuit 24. In addition, by configuring the user controller 9 and the control circuit 24 so as to be connected via a LAN (Local Area Network) or Wi-Fi (registered trademark), a personal computer, a smart phone, a tablet, or the like is used as the user controller 9. Is also possible.
　また、制御回路２４は充放電器２２にも接続されており、充放電器２２は制御回路２４により制御されている。 The control circuit 24 is also connected to the charger / discharger 22, and the charger / discharger 22 is controlled by the control circuit 24.
　上記により、車両コンタクタ５２が動作（ＯＮ）している時に、車両用電力変換装置２から出力される電力により駆動用蓄電池５３を充電することができる。より詳細には、電気的動作スイッチ２８および車両コンタクタ５２が共に動作（ＯＮ）していて、車両用電力変換装置２と車両６とが充電ケーブル８を介して接続されている時に、充放電器２２に蓄えられている電力を放電して、充電ケーブル８を介して駆動用蓄電池５３を充電することができる。 As described above, when the vehicle contactor 52 is operating (ON), the drive storage battery 53 can be charged by the electric power output from the vehicle power converter 2. More specifically, when both the electrical operation switch 28 and the vehicle contactor 52 are operating (ON) and the vehicle power converter 2 and the vehicle 6 are connected via the charging cable 8, the charger / discharger The storage battery 53 for driving can be charged via the charging cable 8 by discharging the electric power stored in the battery 22.
　充電ケーブル８は、接地線３２および充放電コネクタ接続確認線３３をさらに有している。充放電コネクタ接続確認線３３は、後述する接続検出器２３に充電ケーブル８の接続状態を検出させるための信号線である。車両６は、車両内電源５１、充放電コネクタ接続確認用フォトカプラ３７および充放電コネクタ接続電圧分圧抵抗５４をさらに備えている。車両用電力変換装置２は、接続検出器２３および充放電コネクタ接続電圧分圧抵抗２５をさらに備えている。電気的動作スイッチ２８は車両用電力変換装置２の接地点２０に接続され、車両コンタクタ５２は車両６の接地点６０に接続されている。接地点２０と接地点６０とは接地線３２により接続される構成になっている。車両内電源５１は、充放電コネクタ接続確認用フォトカプラ３７、充放電コネクタ接続電圧分圧抵抗５４、充放電コネクタ接続確認線３３および充放電コネクタ接続電圧分圧抵抗２５を経て接地点２０に接続される構成になっている。 The charging cable 8 further includes a ground line 32 and a charge / discharge connector connection confirmation line 33. The charge / discharge connector connection confirmation line 33 is a signal line for causing the connection detector 23 described later to detect the connection state of the charging cable 8. The vehicle 6 further includes an in-vehicle power supply 51, a charge / discharge connector connection confirmation photocoupler 37, and a charge / discharge connector connection voltage dividing resistor 54. The vehicle power conversion device 2 further includes a connection detector 23 and a charge / discharge connector connection voltage voltage dividing resistor 25. The electrical operation switch 28 is connected to the ground point 20 of the vehicle power converter 2, and the vehicle contactor 52 is connected to the ground point 60 of the vehicle 6. The ground point 20 and the ground point 60 are connected by a ground line 32. The in-vehicle power source 51 is connected to the grounding point 20 through the charge / discharge connector connection confirmation photocoupler 37, the charge / discharge connector connection voltage dividing resistor 54, the charge / discharge connector connection confirmation line 33 and the charge / discharge connector connection voltage dividing resistor 25. It is configured to be.
　車両用電力変換装置２と車両６とが充電ケーブル８を介して接続されている場合、充放電コネクタ接続確認用フォトカプラ３７には車両内電源５１より電力が供給され、車両内電源５１が与える電圧は、充放電コネクタ接続電圧分圧抵抗２５および５４によって分圧される。充放電コネクタ接続電圧分圧抵抗５４と充放電コネクタ接続電圧分圧抵抗２５との間で分圧された電圧は接続検出器２３に入力される。接続検出器２３は、入力された電圧に基づいて、車両用電力変換装置２と車両６とが充電ケーブル８を介して電気的に接続されているか否かを検出することができる。 When the vehicle power conversion device 2 and the vehicle 6 are connected via the charging cable 8, power is supplied from the in-vehicle power source 51 to the charge / discharge connector connection confirmation photocoupler 37, and the in-vehicle power source 51 gives the power. The voltage is divided by the charge / discharge connector connection voltage dividing resistors 25 and 54. The voltage divided between the charge / discharge connector connection voltage dividing resistor 54 and the charge / discharge connector connection voltage dividing resistor 25 is input to the connection detector 23. The connection detector 23 can detect whether or not the vehicle power conversion device 2 and the vehicle 6 are electrically connected via the charging cable 8 based on the input voltage.
　車両用電力変換装置２と車両６とが充電ケーブル８を介して電気的に接続されている場合は、接続検出器２３には上記した分圧された電圧が印加され、車両用電力変換装置２と車両６とが充電ケーブル８を介して電気的に接続されていない場合は、接続検出器２３に与えられる電圧は充放電コネクタ接続電圧分圧抵抗２５によりプルダウンされ、接続検出器２３にはＧＮＤレベル（０Ｖ）が印加される。接続検出器２３は印加された電圧に基づいて、車両用電力変換装置２と車両６とが充電ケーブル８を介して接続されているか否かを検出することができる。なお、離脱部３が離脱部凸側３ａおよび離脱部凹側３ｂに離脱する場合の他、充電プラグ４と車両側コネクタ５との電気的な接続が遮断された場合にも、接続検出器２３にＧＮＤレベル（０Ｖ）が印加されて、車両用電力変換装置２と車両６とが充電ケーブル８を介して電気的に接続されていないことが検出される。接続検出器２３による検出結果は、制御回路２４に送られる。 When the vehicle power converter 2 and the vehicle 6 are electrically connected via the charging cable 8, the divided voltage is applied to the connection detector 23, and the vehicle power converter 2 When the vehicle 6 and the vehicle 6 are not electrically connected via the charging cable 8, the voltage applied to the connection detector 23 is pulled down by the charge / discharge connector connection voltage dividing resistor 25, and the connection detector 23 is connected to GND. A level (0 V) is applied. The connection detector 23 can detect whether or not the vehicle power converter 2 and the vehicle 6 are connected via the charging cable 8 based on the applied voltage. The connection detector 23 is used not only when the separation part 3 is separated from the separation part convex side 3a and the separation part concave side 3b but also when the electrical connection between the charging plug 4 and the vehicle-side connector 5 is interrupted. A GND level (0 V) is applied to the vehicle power detection device 2, and it is detected that the vehicle power conversion device 2 and the vehicle 6 are not electrically connected via the charging cable 8. The detection result by the connection detector 23 is sent to the control circuit 24.
　したがって、充電ケーブル８に一定のテンションが掛かって充電ケーブル８の離脱部３が離脱部凸側３ａおよび離脱部凹側３ｂに離脱した場合のように、車両用電力変換装置２と車両６とが充電ケーブル８を介して電気的に接続されていないことを接続検出器２３が検出すると、制御回路２４は車両用電力変換装置２と車両６とが充電ケーブル８を介して電気的に接続していないという検出結果を信号として受け取る。制御回路２４は、当該検出結果を接続検出器２３から受け取ると、電気的動作スイッチ２７を解列（ＯＦＦ）して、電気的動作スイッチ２８への電気的動作スイッチ駆動用電源５０からの電力供給を停止する。これにより、電気的動作スイッチ２８は解列（ＯＦＦ）される。 Accordingly, the vehicle power conversion device 2 and the vehicle 6 are connected to each other as in the case where a certain tension is applied to the charging cable 8 and the detaching portion 3 of the charging cable 8 is detached to the detaching portion convex side 3a and the detaching portion concave side 3b. When the connection detector 23 detects that it is not electrically connected via the charging cable 8, the control circuit 24 connects the vehicle power converter 2 and the vehicle 6 via the charging cable 8. The detection result that there is no is received as a signal. When the control circuit 24 receives the detection result from the connection detector 23, the control circuit 24 disconnects the electrical operation switch 27 (OFF) and supplies power to the electrical operation switch 28 from the power supply 50 for driving the electrical operation switch. To stop. Thereby, the electrical operation switch 28 is disconnected (OFF).
　したがって、充電ケーブル８が車両６に接続されていない場合または充電ケーブル８の離脱部３が離脱した場合といったように充電ケーブル８を介して車両用電力変換装置２と車両６とが電気的に接続していない状態になった場合は、電気的動作スイッチ２８が解列（ＯＦＦ）することにより、充電ケーブル８および車両６に車両用電力変換装置２から供給される高電圧の出力電力を速やかに遮断することができる。 Therefore, the vehicle power converter 2 and the vehicle 6 are electrically connected via the charging cable 8 such as when the charging cable 8 is not connected to the vehicle 6 or when the detaching portion 3 of the charging cable 8 is disconnected. When the electric power switch 28 is not in the state, the electric operation switch 28 is disconnected (OFF), so that the high-voltage output power supplied from the vehicle power converter 2 to the charging cable 8 and the vehicle 6 can be quickly obtained. Can be blocked.
　上記のように、車両用電力変換装置２と車両６とが充電ケーブル８を介して接続されていない状態になった場合に、制御回路２４が、離脱部３または充電プラグ４へ高電圧が出力されるのを防ぐように電気的動作スイッチ２８を制御することにより、ユーザーが高電圧に接触しないように保護することができる。これにより、ユーザーに対する安全性を確保した車両用電力変換装置２と車両６との接続システムを提供することが可能となる。 As described above, when the vehicle power conversion device 2 and the vehicle 6 are not connected via the charging cable 8, the control circuit 24 outputs a high voltage to the disconnecting unit 3 or the charging plug 4. By controlling the electrical operation switch 28 to prevent it from being done, it is possible to protect the user from touching the high voltage. As a result, it is possible to provide a connection system between the vehicle power conversion device 2 and the vehicle 6 that ensures safety for the user.
　また、制御回路２４は、上記動作と共に、ユーザーコントローラ９に車両用電力変換装置２と車両６とが充電ケーブル８を介して電気的に接続されていないこと、すなわち充電ケーブル８が非接続状態であることを通知することもできる。これにより、ユーザーコントローラ９は、表示部９０に充電ケーブル８が非接続状態であることを表示することができるので、ユーザーは充電ケーブル８の状態を把握することが可能となる。充電ケーブル８の接続状態については、ユーザーがユーザーコントローラ９を操作することにより表示部９０に表示されるようにして、ユーザーが充電ケーブル８の接続状態を監視できるような構成としてもよい。 In addition to the above-described operation, the control circuit 24 confirms that the vehicle power converter 2 and the vehicle 6 are not electrically connected to the user controller 9 via the charging cable 8, that is, the charging cable 8 is not connected. You can also be notified. As a result, the user controller 9 can display on the display unit 90 that the charging cable 8 is in a disconnected state, so that the user can grasp the state of the charging cable 8. The connection state of the charging cable 8 may be displayed on the display unit 90 by the user operating the user controller 9 so that the user can monitor the connection state of the charging cable 8.
　なお、制御回路２４は、車両用電力変換装置２と車両６とが充電ケーブル８を介して接続されていないという検出結果を接続検出器２３から受け取った場合に、制御回路２４により電気的動作スイッチ２８を解列（ＯＦＦ）させて、ユーザーが高電圧に接触しないように保護していたが、電気的動作スイッチ２６を解列（ＯＦＦ）させて、ユーザーに対する安全性を高めてもよい。 When the control circuit 24 receives a detection result from the connection detector 23 that the vehicle power conversion device 2 and the vehicle 6 are not connected via the charging cable 8, the control circuit 24 performs an electrical operation switch. 28 is disconnected (OFF) to protect the user from contact with a high voltage. However, the electrical operation switch 26 may be disconnected (OFF) to improve safety for the user.

In addition, when the vehicle 6 needs to travel suddenly in an emergency such as a disaster, the vehicle connection lock release function of the charging cable 8 breaks down and the charging plug 4 cannot be removed from the vehicle-side connector 5. Even in this case, the charging cable 8 can be disconnected at the detaching portion 3, so that the vehicle 6 can travel. That is, according to the vehicular power conversion device 2 according to the first embodiment, even when the charging cable 8 is subjected to a force from the side surface direction, the detachment portion is applied when a tension greater than a predetermined value is applied. Since 3 is detached, it is possible to avoid the failure of the charging cable 8, the vehicle power converter 2 or the vehicle 6. In addition, since the detachment part metal 34a and the detachment part metal 34b are coupled by magnetic force, the detachment of the detachment part convex side 3a and the detachment part concave side 3b can be easily performed.
