Description

本発明は、給電コネクタ延長装置に関する。 The present invention relates to a power supply connector extension device.

電気自動車の車載電池に電力を急速充電する急速充電器やＶ２Ｈ（Vehicle to Home）では、充電時の安全を確保するために、ロック機構を内蔵した給電コネクタを使用している。 Quick chargers and V2H (Vehicle to Home), which quickly charge the in-vehicle battery of an electric vehicle, use a power supply connector with a built-in lock mechanism to ensure safety during charging.

急速充電器からバスやトラック等の大型電気自動車に電力を充電する場合、車両の給電口が遠いため、電線長の長い給電コネクタを使用し、急速充電器からの給電コネクタと延長用の給電コネクタを接続する延長装置を使用していた。 When charging power from a quick charger to a large electric vehicle such as a bus or truck, the power supply port of the vehicle is far away, so use a power supply connector with a long wire length, and use a power supply connector from the quick charger and a power supply connector for extension.

特許第６１６４０８１号公報Japanese Patent No. 6164081

しかしながら、電線長の長い給電コネクタを使用した場合には、ケーブルの絡まりや散乱のために利便性が著しく低下する。このため、大型車両専用の急速充電器となってしまう。 However, when a power supply connector having a long wire length is used, the convenience is significantly reduced due to entanglement and scattering of the cable. Therefore, it becomes a quick charger dedicated to large vehicles.

また、ロック機構の回路は、急速充電器に接続された給電コネクタまでの回路となるため、延長装置を使用して給電コネクタを延長するだけでは、ロック機構の信号が延長用の給電コネクタまで出力されない。このため、車両に接続する延長用の給電コネクタをロックすることができなかった。 In addition, since the circuit of the lock mechanism is a circuit up to the power supply connector connected to the quick charger, the signal of the lock mechanism is output to the power supply connector for extension simply by extending the power supply connector using the extension device. Not done. Therefore, it was not possible to lock the extension power supply connector connected to the vehicle.

A connector lock signal flows from the first lock mechanism signal lines S6 and S7 to the resistors R1 and LED1, and the LED1 lights up. By this lighting, it can be seen that the power supply connector 2 is locked.
The power supply connector extension device 3 connects the power supply connector 2 and the electric vehicle 4, and includes an inlet 31, a cable 6b, and a power supply connector 32 (corresponding to the second power supply connector of the present invention).

インレット３１は、ソケット又はコンセント等であり、給電コネクタ２に接続し、充電器１からの電力を伝送する電力線ＰＷ１と、給電コネクタ２の複数の第１信号線Ｓ１〜Ｓ５とを有する。 The inlet 31 is a socket, an outlet, or the like, and has a power line PW1 that is connected to the power supply connector 2 and transmits power from the charger 1, and a plurality of first signal lines S1 to S5 of the power supply connector 2.

A lock signal flows from the second lock mechanism signal lines S10 and S11 to the resistors R2 and LED2, and the LED2 lights up. By this lighting, it can be seen that the power supply connector 32 is locked.

図３は、本発明の実施形態に係る電気自動車充電システムに設けられた電気自動車の構成ブロック図である。電気自動車は、給電コネクタ３２の電力線ＰＷ１に接続されるリレー４１ａ，４１ｂ、リレー４１ａ，４１ｂ間に接続されるバッテリ４２、給電コネクタ３２の信号線Ｓ１〜Ｓ５に接続される送受信部４３と、ＣＰＵ４４とを備える。 FIG. 3 is a block diagram of an electric vehicle provided in the electric vehicle charging system according to the embodiment of the present invention. The electric vehicle includes relays 41a and 41b connected to the power line PW1 of the power supply connector 32, a battery 42 connected between the relays 41a and 41b, a transmission / reception unit 43 connected to the signal lines S1 to S5 of the power supply connector 32, and a CPU 44. And.

リレー４１ａ，４１ｂは、ＣＰＵ４４からのＥＶリレーオン信号によりオンし、給電コネクタ３２の電力線ＰＷ１からの電力によりバッテリ４２を充電する。ＣＰＵ４４は、送受信部４３が充電器１から充電開始信号を受信すると、充電許可信号を生成する。送受信部４３は、ＣＰＵ４４からの充電許可信号を信号線Ｓ２を介して充電器１に送信する。 The relays 41a and 41b are turned on by the EV relay on signal from the CPU 44, and the battery 42 is charged by the power from the power line PW1 of the power supply connector 32. When the transmission / reception unit 43 receives the charging start signal from the charger 1, the CPU 44 generates a charging permission signal. The transmission / reception unit 43 transmits the charge permission signal from the CPU 44 to the charger 1 via the signal line S2.

また、信号線Ｓ１には、充電器１の電圧が印加されている期間よりも長い期間オンするコネクタロック信号が充電器１から出力される。コネクタロック信号は、充電器１により電気自動車４のバッテリ４２を充電していない期間にはオフする。コネクタロック信号は、電気自動車４のバッテリ４２に充電を開始するための充電開始信号である。 Further, a connector lock signal that is turned on for a longer period than the period in which the voltage of the charger 1 is applied is output from the charger 1 to the signal line S1. The connector lock signal is turned off during the period when the battery 42 of the electric vehicle 4 is not charged by the charger 1. The connector lock signal is a charging start signal for starting charging of the battery 42 of the electric vehicle 4.

次に、このように構成された実施形態に係る給電コネクタ延長装置３を含む電気自動車充電システムの動作を図４に示す各部のタイミングチャートを参照しながら詳細に説明する。 Next, the operation of the electric vehicle charging system including the power supply connector extension device 3 according to the embodiment configured as described above will be described in detail with reference to the timing chart of each part shown in FIG.

まず、充電器１において、スタートボタン１２を押すと、充電器スタートトリガが時刻ｔ１〜ｔ２にハイレベルとなる。ＣＰＵ１３は、スタートボタン１２からの充電器スタートトリガのダウンエッジ、即ち時刻ｔ２の数秒後ｔ３において、充電開始信号を生成し、ケーブル６ａを介して給電コネクタ２の信号線Ｓ１に出力する。 First, when the start button 12 is pressed on the charger 1, the charger start trigger becomes a high level at times t1 to t2. The CPU 13 generates a charging start signal at the down edge of the charger start trigger from the start button 12, that is, at t3 a few seconds after the time t2, and outputs the charging start signal to the signal line S1 of the power supply connector 2 via the cable 6a.

充電開始信号は、給電コネクタ２の信号線Ｓ１、インレット３１の信号線Ｓ１、ケーブル６ｂ、給電コネクタ３２の信号線Ｓ１を介して電気自動車４の送受信部４３に送られる。ＣＰＵ４４は、送受信部４３からの充電開始信号に基づき時刻ｔ４にハイレベルの充電許可信号を生成し、充電許可信号を送受信部４３、信号線Ｓ２を介して充電器１に送信する。 The charging start signal is sent to the transmission / reception unit 43 of the electric vehicle 4 via the signal line S1 of the power supply connector 2, the signal line S1 of the inlet 31, the cable 6b, and the signal line S1 of the power supply connector 32. The CPU 44 generates a high-level charging permission signal at time t4 based on the charging start signal from the transmission / reception unit 43, and transmits the charging permission signal to the charger 1 via the transmission / reception unit 43 and the signal line S2.

次に、充電器１が充電許可信号を受信すると、充電器１は、時刻ｔ５〜ｔ６に電力変換部１１から充電器出力電圧を給電コネクタ２の電力線ＰＷ１に出力する。このとき、ケーブル６ａ、ケーブル６ｂで地絡等があるかないかの安全確認を行う。 Next, when the charger 1 receives the charging permission signal, the charger 1 outputs the charger output voltage from the power conversion unit 11 to the power line PW1 of the power supply connector 2 at time t5 to t6. At this time, safety confirmation is performed on the cables 6a and 6b to see if there is a ground fault or the like.

充電器１のＣＰＵ１３は、安全確認が取れた場合には、時刻ｔ７に安全確認信号を給電コネクタ２の信号線Ｓ３、インレット３１の信号線Ｓ３、給電コネクタ３２の信号線Ｓ３を介して電気自動車４に送信する。 When the safety confirmation is obtained, the CPU 13 of the charger 1 transmits a safety confirmation signal at time t7 via the signal line S3 of the power supply connector 2, the signal line S3 of the inlet 31, and the signal line S3 of the power supply connector 32. Send to 4.

電気自動車４では、送受信部４３が安全確認信号を受信すると、時刻ｔ８にＣＰＵ４４からのＥＶリレーオン信号のハイレベルによりリレー４１ａ，４１ｂがオンする。このため、充電器１から充電器出力電圧が電気自動車４のバッテリ４２に印加されて、バッテリ４２への充電が行われる。すると、時刻ｔ９から充電器出力電流がバッテリ４２に流れ、時刻ｔ１０には充電器出力電流は一定値となる。 In the electric vehicle 4, when the transmission / reception unit 43 receives the safety confirmation signal, the relays 41a and 41b are turned on by the high level of the EV relay on signal from the CPU 44 at time t8. Therefore, the charger output voltage from the charger 1 is applied to the battery 42 of the electric vehicle 4, and the battery 42 is charged. Then, the charger output current flows to the battery 42 from time t9, and the charger output current becomes a constant value at time t10.

電気自動車４のＣＰＵ４４は、時刻ｔ１１に充電許可信号をオフさせ、オフ信号が信号線Ｓ２を介して充電器１に送信される。時刻ｔ１３にＣＰＵ４４からのＥＶリレーオン信号のローレベルによりリレー４１ａ，４１ｂがオフする。充電器出力電圧は、時刻ｔ１３から低下して時刻ｔ１４にゼロになる。さらに、時刻ｔ１６に安全確認信号がローレベルになる。 The CPU 44 of the electric vehicle 4 turns off the charge permission signal at time t11, and the off signal is transmitted to the charger 1 via the signal line S2. At time t13, the relays 41a and 41b are turned off by the low level of the EV relay on signal from the CPU 44. The charger output voltage drops from time t13 to zero at time t14. Further, the safety confirmation signal becomes low level at time t16.

一方、充電開始信号は、時刻ｔ３〜ｔ１７までハイレベルとなる。充電開始信号は、給電コネクタ２の信号線Ｓ１、インレット３１の信号線Ｓ１を通る。このとき、インレット３１の出力側で信号線Ｓ１には並列に信号線Ｓ８が接続され、信号線Ｓ４には、信号線Ｓ９が並列に接続されている。
このため、充電開始信号は、信号線Ｓ８を通り、給電コネクタ３２のロック機構信号線Ｓ１０に送られる。即ち、充電開始信号をコネクタロック信号として用い、コネクタロック信号により第２ロック機構が動作して、電気自動車４に接続する延長用の給電コネクタ３２もロックすることができる。 On the other hand, the charging start signal becomes a high level from time t3 to t17. The charging start signal passes through the signal line S1 of the power supply connector 2 and the signal line S1 of the inlet 31. At this time, the signal line S8 is connected in parallel to the signal line S1 on the output side of the inlet 31, and the signal line S9 is connected in parallel to the signal line S4.
Therefore, the charging start signal passes through the signal line S8 and is sent to the lock mechanism signal line S10 of the power supply connector 32. That is, the charging start signal is used as the connector lock signal, and the second lock mechanism operates by the connector lock signal to lock the extension power supply connector 32 connected to the electric vehicle 4.

また、コネクタロック信号は、充電器１の電圧が印加されている期間よりも長い期間オンするので、確実に充電器１の電圧が印加されている期間は給電コネクタ３２をロックすることができる。 Further, since the connector lock signal is turned on for a period longer than the period during which the voltage of the charger 1 is applied, the power supply connector 32 can be reliably locked during the period when the voltage of the charger 1 is applied.

また、コネクタロック信号は、充電器１により電気自動車４のバッテリを充電していない期間にはオフするので、給電コネクタ３２に電圧が印加されることはない。 Further, since the connector lock signal is turned off during the period when the battery of the electric vehicle 4 is not charged by the charger 1, no voltage is applied to the power supply connector 32.

また、充電器１からの充電開始信号をコネクタロック信号に用いることで、特別な信号を用いることがなくなり、信号処理が簡単になる。 Further, by using the charging start signal from the charger 1 as the connector lock signal, it is not necessary to use a special signal, and signal processing becomes simple.

さらに、装置停止時には、ＣＰＵ１３は、充電器１の出力電圧を計測し、その計測値が所定値以下にならない場合には、充電開始信号をオフしないように制御する。また、充電開始信号は、充電器１と電気自動車４のバッテリ４２との接続を行うリレー４１ａ，４１ｂのオンオフ信号にも使用されているため、この信号がオフとなった場合には、バッテリ４２の電圧が給電コネクタ３２に印加されることはない。 Further, when the device is stopped, the CPU 13 measures the output voltage of the charger 1 and controls so that the charging start signal is not turned off when the measured value does not fall below a predetermined value. Further, since the charging start signal is also used as an on / off signal of the relays 41a and 41b for connecting the charger 1 and the battery 42 of the electric vehicle 4, when this signal is turned off, the battery 42 The voltage of is not applied to the power feeding connector 32.

なお、実施形態に係る給電コネクタ延長装置では、ロック機構として電磁ソレノイドを例示したが、これに限定されることなく、ラッチ回路を用いて良い。また、コネクタロック信号として、充電開始信号を用いたが、充電開始信号に限定されるものではなく、充電器１の電圧が印加されている期間よりも長い期間オンする信号であれば、その他の信号を用いても良い。 In the power supply connector extension device according to the embodiment, an electromagnetic solenoid is exemplified as a lock mechanism, but the present invention is not limited to this, and a latch circuit may be used. Further, although the charging start signal is used as the connector lock signal, it is not limited to the charging start signal, and other signals as long as the signal is turned on for a longer period than the period in which the voltage of the charger 1 is applied. A signal may be used.
