Description
【0001】[0001]
本考案は別置型充電器に関し、特に電気自動車の走行用電池を充電するための 充電設備に適用することができる。 INDUSTRIAL APPLICABILITY The present invention relates to a stand-alone charger, and is particularly applicable to charging equipment for charging a running battery of an electric vehicle.
【0002】[0002]
別置型充電器はたとえば200Vの単相又は三相電源を入力とし、これを整流 してたとえば直流240Vにし、これを適当な充電コネクタを介して電気自動車 の走行用電池に給電するもので、車両とは別の特定の場所に据え付けられている 充電器である。 The separate type charger uses, for example, a 200V single-phase or three-phase power source as input, rectifies it to, for example, 240V DC, and supplies this to a running battery of an electric vehicle through an appropriate charging connector. It is a charger installed in a specific place other than.
【0003】 走行用電池を充電するには、走行用電池と充電器とを電気的に接続しなければ ならないが、この接続は着脱自在な充電コネクタによって行っている。この充電 コネクタは充電を行う時に接続され、充電が完了すると外される。To charge the traveling battery, the traveling battery and the charger have to be electrically connected, and this connection is made by a detachable charging connector. This charging connector is connected when charging and removed when charging is complete.
【0004】[0004]
別置型充電器で走行用電池を充電するときには、まず充電コネクタで両者を電 気的に接続し、充電器の充電開始スイッチを入れることで充電が開始される。充 電が完了すれば充電器の作動を停止させ、充電コネクタを外すことで、走行用電 池の充電が終了する。 When the traveling battery is charged with the separate charger, first the two are electrically connected with the charging connector, and charging is started by turning on the charging start switch of the charger. When charging is completed, the charger will stop operating and the charging connector will be removed to finish charging the running battery.
【0005】 ところで、充電器作動中に充電コネクタを外した場合、充電コネクタの充電器 側及び走行用電池側の端子間に電気アークが発生する。この電気アークは直流の 高電圧を給電の場合連続して発生するもので、走行用電池にたとえば240Vの 直流の高電圧を給電しているとすれば、端子間の距離が30mm程度離れても消 えることがない。つまり充電コネクタの端子を機械的に離しても電気的には切れ ていない状態にあり、電気アークは連続して発生する。このような電気アークは 充電コネクタを外している途中にその端子部より発生するため、充電操作者が感 電したり火傷したりする危険性が非常に大きいのである。By the way, when the charging connector is detached during operation of the charger, an electric arc is generated between the terminals of the charging connector on the charger side and the traveling battery side. This electric arc is continuously generated when a high voltage of direct current is supplied, and if a high voltage of direct current of 240 V, for example, is supplied to the running battery, even if the distance between the terminals is about 30 mm. It never disappears. In other words, even if the terminals of the charging connector are mechanically separated, they are not electrically disconnected, and an electric arc is continuously generated. Since such an electric arc is generated from the terminal part of the charging connector while the charging connector is being removed, there is a great risk that the charging operator may get an electric shock or get burned.
【0006】 本考案は上記事情にかんがみてなされたもので、充電器が作動した状態で充電 コネクタを着脱しても充電コネクタの端子部より電気アークが発生しない別置型 充電器を提供することを目的とする。The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a separate-type charger in which an electric arc is not generated from a terminal portion of the charging connector even when the charging connector is detached and attached while the charger is operating. To aim.

And a means for stopping the operation of the charger when it is detected that a separate charger is provided.

図1は本考案による別置型充電器の好適な一実施例を示す構成図である。図1 において、別置型充電器1は充電回路2を有し、入力には例えば単相交流200 Vの商用電源が接続され、出力には充電コネクタ3を介して電気自動車の走行用 電池4に接続されて、たとえば直流240Vで30Aの定電流を供給できる構成 となっている。 FIG. 1 is a block diagram showing a preferred embodiment of a separate type charger according to the present invention.

When connected, a constant current of, for example, 240 V DC and 30 A can be supplied.
【0010】 充電コネクタ3は、充電電流用の1対の端子の他、断線検知用の1対の端子を 有しており、その断線検知用端子の走行用電池側は単にそれらを電気的に接続し た短絡線が設けられている。充電コネクタ3の充電回路側の断線検知用端子は一 方は充電回路のたとえば直流24Vの電源線に接続され、他方は充電回路2の充 電開始及び停止を制御するリレー5の励磁コイルの一端に接続されている。励磁 コイルの他端はそのリレー接点及び充電開始スイッチ6を介して接地されている 。別のリレー接点は充電回路2の充電作動を開始又は停止させる充電制御端子7 及び充電・停止スイッチ8に接続されている。The charging connector 3 has a pair of terminals for charging current as well as a pair of terminals for disconnection detection, and the traveling battery side of the disconnection detection terminal simply electrically connects them. A connected short-circuit wire is provided. One of the disconnection detection terminals on the charging circuit side of the charging connector 3 is connected to, for example, a DC 24V power line of the charging circuit, and the other is one end of an exciting coil of the relay 5 for controlling the start and stop of charging of the charging circuit 2. It is connected to the. The other end of the exciting coil is grounded via its relay contact and charging start switch 6. Another relay contact is connected to the charge control terminal 7 and the charge / stop switch 8 for starting or stopping the charging operation of the charging circuit 2.
【0011】 走行用電池4の充電を行う場合、充電・停止スイッチ8を投入し、かつ充電コ ネクタ3を接続してその充電電流用端子及び断線検知用端子を同時に接続する。 ここで、充電開始スイッチ6を押すことにより、リレー5が作動し、それらの接 点を閉成する。これにより、リレー5はその励磁コイルの回路が閉成するため自 己保持され、充電回路2の充電作動を開始又は停止させる充電制御端子7が接地 されることにより充電回路2が作動し充電が開始される。充電を停止する場合に は充電・停止スイッチ8を切ることで、充電制御端子7の回路が開成され、充電 回路2は充電作動を停止する。When the traveling battery 4 is charged, the charge / stop switch 8 is turned on, and the charging connector 3 is connected to connect the charging current terminal and the disconnection detection terminal at the same time. Here, by pressing the charging start switch 6, the relay 5 is activated and the contact points thereof are closed. As a result, the relay 5 is held by itself because the circuit of its exciting coil is closed, and the charging control terminal 7 for starting or stopping the charging operation of the charging circuit 2 is grounded, so that the charging circuit 2 operates and charging is performed. Be started. When the charging is stopped, the charging / stop switch 8 is turned off to open the circuit of the charging control terminal 7 and the charging circuit 2 stops the charging operation.
【0012】 ここで、充電中に充電プラグ3を外した場合には、リレー5の励磁コイルの回 路が開成されるため、リレー5は消勢され、それらの接点は開成される。これに より、リレー5の自己保持は解除されると共に充電制御端子7の回路が開成され ることで、充電回路2は充電作動を停止する。したがって、充電コネクタ3の充 電電流用端子での電気アークの発生はなくなる。この例では、充電コネクタを外 す操作を検出する手段は充電コネクタ3の断線検知用端子及びリレー5によって 構成され、充電器の作動を停止させる手段は充電回路2の充電制御端子7に接続 されたリレー5の接点によって構成されることになる。Here, when the charging plug 3 is removed during charging, the circuit of the exciting coil of the relay 5 is opened, so that the relay 5 is deenergized and their contacts are opened. As a result, the self-holding of the relay 5 is released and the circuit of the charging control terminal 7 is opened, so that the charging circuit 2 stops the charging operation. Therefore, no electric arc is generated at the charging current terminal of the charging connector 3. In this example, the means for detecting the operation of disconnecting the charging connector is constituted by the disconnection detection terminal of the charging connector 3 and the relay 5, and the means for stopping the operation of the charger is connected to the charging control terminal 7 of the charging circuit 2. It will be composed of the contacts of the relay 5.

【0014】 図2の実施例において、充電コネクタ3の断線検知用端子はパワーリレー9の 励磁コイルに接続され、そのリレー接点は充電回路2に交流電源を入力する電源 線に挿入されている。In the embodiment of FIG. 2, the disconnection detection terminal of the charging connector 3 is connected to the exciting coil of the power relay 9, and the relay contact is inserted in the power supply line for inputting the AC power supply to the charging circuit 2.
【0015】 この実施例では、充電コネクタ3の引き外しに応動してパワーリレー9が消勢 され、充電器1の電源を遮断することによって充電を停止させるもので、充電コ ネクタを外す操作を検出する手段を充電コネクタ3の断線検知用端子で構成し、 充電器の作動を停止させる手段をパワーリレー9で構成している。In this embodiment, the power relay 9 is deenergized in response to the disconnection of the charging connector 3, and the charging is stopped by shutting off the power supply of the charger 1. Therefore, the operation of removing the charging connector is performed. The detecting means is constituted by the disconnection detection terminal of the charging connector 3, and the means for stopping the operation of the charger is constituted by the power relay 9.

The charging connector is composed of, for example, a receptacle 11 provided on the vehicle and a plug 12 provided on the output cable of the charger. It is connected to the male contact 14. A permanent magnet 16 is provided on the latch lever 15 of the plug 12, and a magnetoresistive element 17 is provided at a position facing the permanent magnet 16. That is, the movement of the latch lever 15 which is an operation when the plug 12 is detached from the receptacle 11 is detected by the magnetoresistive element 17, and a change in the magnetic field of the permanent magnet 16 is detected by the electric resistance of the magnetoresistive element 17. It is detected by the change in resistance, and the determination is made in the charging circuit. A Hall element, a magnetic diode, a magnetic transistor, or the like can be used as the magnetoresistive element 17.
