(実施形態1)
実施形態1の電動車両用充電装置について図面を参照しながら説明する。
(Embodiment 1)
The electric vehicle charging device of Embodiment 1 will be described with reference to the drawings.
図6は電動車両用充電装置(以下、充電装置と略す。)1Aの概略構成を示すブロック図である。この充電装置1Aは、充電制御部2と、表示部3と、操作入力部4と、リレーR1と、零相変流器(ZCT)5と、端子台TB1,TB2を備え、これらを充電装置本体10に保持させて構成されている。   FIG. 6 is a block diagram showing a schematic configuration of an electric vehicle charging device (hereinafter abbreviated as a charging device) 1A. This charging device 1A includes a charging control unit 2, a display unit 3, an operation input unit 4, a relay R1, a zero-phase current transformer (ZCT) 5, and terminal blocks TB1 and TB2. The main body 10 is configured to be held.
端子台TB1には電源ケーブルCB1の一端側が接続され、この電源ケーブルCB1の他端側には例えば商用交流電源の電源コンセントに着脱自在に接続するための電源コネクタCN1が接続されている。端子台TB2には充電ケーブルCB2の一端側が接続されており、この充電ケーブルCB2の他端側には電動車両100の充電コネクタ103に着脱自在に接続される充電コネクタCN2が接続されている。なお、充電コネクタCN2は、人が把持する把持部110と、把持部110の先端側から斜め上前方に突出し、先端が車両側の充電コネクタ103に着脱自在に接続される接続部111とを一体に備えている。ここで、電源ケーブルCB1は、電圧極の2本の電線L1,L2と、接地線L3とで構成される。また、充電ケーブルCB2は、電圧極の2本の電線L1,L2と、接地線L3と、電動車両100が備える充電回路101との間で信号(所謂CPLT信号)を授受するための電線L4とで構成される。   One end side of a power cable CB1 is connected to the terminal block TB1, and a power connector CN1 for detachably connecting to a power outlet of a commercial AC power source, for example, is connected to the other end side of the power cable CB1. One end of a charging cable CB2 is connected to the terminal block TB2, and a charging connector CN2 that is detachably connected to the charging connector 103 of the electric vehicle 100 is connected to the other end of the charging cable CB2. The charging connector CN2 is integrally formed with a gripping part 110 gripped by a person and a connection part 111 that protrudes obliquely upward and forward from the front end side of the gripping part 110 and whose front end is detachably connected to the charging connector 103 on the vehicle side. In preparation. Here, the power cable CB1 is composed of two electric wires L1 and L2 having voltage poles and a ground line L3. Charging cable CB2 includes electric wires L4 for transmitting and receiving a signal (so-called CPLT signal) between two electric wires L1 and L2 having voltage poles, grounding wire L3, and charging circuit 101 provided in electric vehicle 100. Consists of.
リレーR1が備える2極の接点は、端子台TB1,TB2の端子間を接続する内部の導電路のうち、電圧極の電線L1,L2にそれぞれ接続される導電路にそれぞれ接続されている。リレーR1の接点は充電制御部2によってオン/オフが制御され、接点がオンされると電動車両100に電源が供給され、接点がオフされると電動車両100への電源供給が遮断される。なお、リレーR1のリレー接点はノーマリ・オフ型の接点であり、電動車両100から充電制御部2に充電開始信号が入力されると、充電制御部2によってリレーR1が開状態から閉状態に切り替えられ、電動車両100へと電力が供給される。   The two-pole contacts provided in the relay R1 are respectively connected to the conductive paths connected to the electric wires L1 and L2 of the voltage pole among the internal conductive paths connecting the terminals of the terminal blocks TB1 and TB2. The contact of the relay R1 is controlled to be turned on / off by the charging control unit 2. When the contact is turned on, power is supplied to the electric vehicle 100, and when the contact is turned off, power supply to the electric vehicle 100 is cut off. Note that the relay contact of the relay R1 is a normally-off contact, and when a charge start signal is input from the electric vehicle 100 to the charge control unit 2, the charge control unit 2 switches the relay R1 from the open state to the closed state. Then, electric power is supplied to the electric vehicle 100.
零相変流器5は、リレーR1よりも電動車両100側の電路で漏電が発生した際に、電圧極の電線L1,L2間に発生する不平衡電流を検出するために用いられる。   The zero-phase current transformer 5 is used to detect an unbalanced current generated between the voltage electrode wires L1 and L2 when a leakage occurs in the electric circuit closer to the electric vehicle 100 than the relay R1.
充電制御部2は、電動車両100の充電回路101から電線L4を介して入力される信号に基づいて、リレーR1を開極又は閉極させ、電動車両100への電力供給をオン/オフすることによって、電動車両100の充電を制御する。また充電制御部2は、充電中に零相変流器5の出力をもとに漏電発生を検知すると、リレーR1を開極させて、電動車両100への電力供給を遮断する。   The charging control unit 2 opens or closes the relay R1 based on a signal input from the charging circuit 101 of the electric vehicle 100 via the electric wire L4 to turn on / off the power supply to the electric vehicle 100. Thus, charging of the electric vehicle 100 is controlled. In addition, when the charging control unit 2 detects the occurrence of electric leakage based on the output of the zero-phase current transformer 5 during charging, the charging control unit 2 opens the relay R1 and cuts off the power supply to the electric vehicle 100.
表示部3は、例えば発光ダイオードのような表示ランプからなり、充電制御部2によって動作状態(例えば点灯、点滅、消灯)が切り替えられ、充電装置1Aの状態表示(例えば充電中や停止中や漏電検知など)を行う。   The display unit 3 includes a display lamp such as a light-emitting diode, for example, and the operation state (for example, lighting, blinking, and extinguishing) is switched by the charging control unit 2, and the status display of the charging device 1A (for example, charging, stopping, or leakage) Detection).

次に、図1〜図3を参照して充電装置1Aの構造を説明する。尚、以下の説明では特に断りがないかぎり、図1に示す向き(壁200への取り付け状態)において上下左右の方向を規定し、図3(b)の左側を前側、右側を後側として説明を行う。   Next, the structure of the charging device 1A will be described with reference to FIGS. In the following description, unless otherwise specified, the vertical and horizontal directions are defined in the direction shown in FIG. 1 (attached to the wall 200), and the left side of FIG. 3B is described as the front side and the right side as the rear side. I do.
充電装置1Aの充電装置本体10は、合成樹脂により略平板状に形成されて、建物の壁200に取り付けられるベース11と、合成樹脂により後面側が開放された縦長の箱状に形成されて、ベース11の前面側に取り付けられるボディ12とで構成される。   The charging device main body 10 of the charging device 1A is formed in a substantially flat plate shape by a synthetic resin, and is formed in a base 11 attached to a wall 200 of a building, and a vertically long box shape whose rear side is opened by a synthetic resin. 11 and a body 12 attached to the front side.
ベース11には、ベース11を前後方向に貫通する挿通孔(図示せず)が設けられ、この挿通孔に通された固定ネジ15(図3(b)参照)を壁200にねじ込むことによって、ベース11が壁200に固定されるようになっている。ここにおいて、固定ネジ15や固定ネジ15を挿通するためにベース11に設けられた挿通孔(図示せず)などから、充電装置本体10を施工場所に取り付けるための取付部が構成される。   The base 11 is provided with an insertion hole (not shown) penetrating the base 11 in the front-rear direction, and by screwing a fixing screw 15 (see FIG. 3B) passed through the insertion hole into the wall 200, The base 11 is fixed to the wall 200. Here, an attachment portion for attaching the charging device main body 10 to the construction site is constituted by a fixing screw 15 or an insertion hole (not shown) provided in the base 11 for inserting the fixing screw 15.
ボディ12には、上述した充電制御部2、表示部3、操作入力部4、リレーR1、零相変流器5、端子台TB1,TB2などの回路部品が保持されており、ボディ12は適宜の方法でベース11に取り付けられている。ボディ12の下部には、左右方向の中央部に前側及び下側に開放されて、充電コネクタCN2の一部が挿入される収納凹部13が設けられている。この収納凹部13には、充電コネクタCN2の先端に設けられた筒状の接続部111が挿入されて、この接続部111を保持するコネクタ保持体14が設けられている。コネクタ保持体14は合成樹脂成形品であって、一端側が閉塞された円筒形状に形成されており、筒内に接続部111の先端側が挿入された状態で充電コネクタCN2を保持している。ボディ12の下面には、電源ケーブルCB1,充電ケーブルCB2をそれぞれ通すための挿通孔が、収納凹部13の左右両側に設けられている。電源ケーブルCB1及び充電ケーブルCB2は、それぞれ対応する挿通孔を通してボディ12内部に導入され、ボディ12内に保持された端子台TB1,TB2に結線されている。またボディ12の前面には、表示部3を構成する複数個(例えば3個)の発光ダイオードLD1,LD2,LD3と、操作入力部4を構成する複数個(例えば2個)の操作スイッチSW1,SW2が上下方向に並べて配置されている。   The body 12 holds circuit components such as the above-described charging control unit 2, display unit 3, operation input unit 4, relay R1, zero-phase current transformer 5, terminal blocks TB1 and TB2, and the body 12 is appropriately It is attached to the base 11 by the method. In the lower part of the body 12, there is provided a storage recess 13 that is open to the front and lower sides in the center in the left-right direction and into which a part of the charging connector CN2 is inserted. A cylindrical connecting portion 111 provided at the tip of the charging connector CN2 is inserted into the housing recess 13 and a connector holding body 14 that holds the connecting portion 111 is provided. The connector holding body 14 is a synthetic resin molded product, and is formed in a cylindrical shape with one end closed, and holds the charging connector CN2 in a state where the tip end side of the connecting portion 111 is inserted into the cylinder. On the lower surface of the body 12, insertion holes for passing the power cable CB <b> 1 and the charging cable CB <b> 2 are provided on both the left and right sides of the storage recess 13. The power cable CB1 and the charging cable CB2 are introduced into the body 12 through corresponding insertion holes, and are connected to the terminal blocks TB1 and TB2 held in the body 12. Further, on the front surface of the body 12, a plurality of (for example, three) light emitting diodes LD1, LD2, and LD3 that constitute the display unit 3, and a plurality of (for example, two) operation switches SW1, that constitute the operation input unit 4. SW2 is arranged in the vertical direction.
充電装置1Aは上記のような構成を有し、図1に示すように充電装置本体10は建物の壁200に設置されている。そして、充電装置本体10の電源コネクタCN1が、同じく壁200に設置された電源コンセント201に接続されると、外部電源である商用交流電源から充電装置1Aに電源が供給される。尚、離れた場所に設置された外部電源(例えば商用交流電源の電源コンセント)からの電源コード202に設けられたレセプタクル型のコネクタ203に電源コネクタCN1を接続することによって、外部電源から充電装置1Aに電源を供給するようにしてもよい。   1 A of charging devices have the above structures, and the charging device main body 10 is installed in the wall 200 of a building as shown in FIG. Then, when the power connector CN1 of the charging device body 10 is connected to a power outlet 201 that is also installed on the wall 200, power is supplied to the charging device 1A from a commercial AC power source that is an external power source. In addition, by connecting the power connector CN1 to the receptacle-type connector 203 provided on the power cord 202 from an external power source (for example, a power outlet of a commercial AC power source) installed at a remote place, the charging device 1A is connected from the external power source. You may make it supply a power supply to.
ここで、充電装置1Aが電動車両100の充電に用いられていない場合、充電コネクタCN2はコネクタ保持体14に保持されている。非充電時に充電コネクタCN2が地面に放置されていると、充電コネクタCN2や充電ケーブルCB2が人や車に踏まれる可能性があるが、本実施形態では非充電時にユーザが充電コネクタCN2をコネクタ保持体14に保持させることができる。したがって、充電コネクタCN2や充電ケーブルCB2が人や車などに踏まれる可能性を低減できる。   Here, when the charging device 1 </ b> A is not used for charging the electric vehicle 100, the charging connector CN <b> 2 is held by the connector holder 14. If the charging connector CN2 is left on the ground during non-charging, the charging connector CN2 or the charging cable CB2 may be stepped on by a person or a vehicle. In this embodiment, the user holds the charging connector CN2 during non-charging. It can be held by the body 14. Therefore, the possibility that the charging connector CN2 and the charging cable CB2 are stepped on by a person or a vehicle can be reduced.
一方、ユーザが充電装置1Aを用いて電動車両100を充電する際には、先ずコネクタ保持体14から外した充電コネクタCN2を電動車両100の充電コネクタ103に接続する。その後、電動車両100側で充電のための準備が完了すると、充電回路101から充電制御部2へ充電開始信号が出力され、充電制御部2がリレーR1を開状態から閉状態に切り替えることによって、電動車両100に電力が供給される。この時、電動車両100では充電回路101がバッテリ102を充電し、バッテリ102の充電が完了すると、充電完了信号を充電制御部2に出力する。充電制御部2は、電動車両100の充電回路101から充電完了信号が入力されると、リレーR1を閉状態から開状態に切り替え、電動車両100への電力供給を停止するとともに、表示部3を用いてユーザに充電が完了したことを報知する。また充電中に電動車両側の電路で漏電が発生した場合、充電制御部2は、零相変流器5の出力をもとに漏電発生を検知することができ、漏電を検知するとリレーR1を開極させることによって、電動車両100への電力供給を遮断する。以上のような動作を充電装置1Aが行うことによって、電動車両100の充電が行われる。   On the other hand, when the user charges the electric vehicle 100 using the charging device 1 </ b> A, the charging connector CN <b> 2 removed from the connector holder 14 is first connected to the charging connector 103 of the electric vehicle 100. After that, when preparation for charging is completed on the electric vehicle 100 side, a charging start signal is output from the charging circuit 101 to the charging control unit 2, and the charging control unit 2 switches the relay R1 from the open state to the closed state, Electric power is supplied to the electric vehicle 100. At this time, in the electric vehicle 100, the charging circuit 101 charges the battery 102, and when the charging of the battery 102 is completed, a charging completion signal is output to the charging control unit 2. When a charging completion signal is input from the charging circuit 101 of the electric vehicle 100, the charging control unit 2 switches the relay R1 from the closed state to the open state, stops the power supply to the electric vehicle 100, and displays the display unit 3 To inform the user that charging is complete. Further, when a leakage occurs in the electric circuit on the electric vehicle side during charging, the charging control unit 2 can detect the occurrence of the leakage based on the output of the zero-phase current transformer 5, and when the leakage is detected, the relay R1 is turned off. By opening the pole, the power supply to the electric vehicle 100 is cut off. When the charging device 1A performs the above operation, the electric vehicle 100 is charged.
上述のように本実施形態の充電装置1Aは、施工場所に取り付けるための取付部(固定ネジ15など)を有する充電装置本体10を備えている。充電装置本体10には、給電対象の電動車両100に着脱自在に接続される充電コネクタCN2が結線された充電ケーブルCB2と、充電コネクタCN2が接続された電動車両100への充電を制御する充電制御部2と、外部電源に接続するための電源コネクタCN1が結線された電源ケーブルCB1とが設けられている。そして、充電装置1Aは、外部電源から電源ケーブルCB1を介して供給を受けた電力を充電ケーブルCB2を介して電動車両100に供給する。   As described above, the charging device 1 </ b> A of the present embodiment includes the charging device main body 10 having an attachment portion (fixing screw 15 or the like) for attachment to a construction site. The charging device body 10 includes a charging cable CB2 that is connected to a charging connector CN2 that is detachably connected to the electric vehicle 100 to be supplied with power, and a charging control that controls charging to the electric vehicle 100 to which the charging connector CN2 is connected. The unit 2 and a power cable CB1 to which a power connector CN1 for connection to an external power source is connected are provided. Then, charging device 1A supplies electric power supplied from an external power source via power cable CB1 to electric vehicle 100 via charging cable CB2.
このように、電源ケーブルCB1には外部電源に接続するための電源コネクタCN1が結線されているので、特別な技能を持たない一般のユーザでも外部電源に接続する作業を容易に行うことができる。したがって、電気工事業者による配線工事が不要であるから、導入コストが安価な電動車両用充電装置1Aを実現することができる。   As described above, since the power supply cable CB1 is connected to the power supply connector CN1 for connecting to the external power supply, even a general user who does not have special skills can easily perform the operation of connecting to the external power supply. Accordingly, since no wiring work is required by an electrician, an electric vehicle charging device 1A can be realized at a low introduction cost.
ところで、本実施形態の充電装置1Aにおいて、図4に示すように電源ケーブルCB1が伸縮電線W1(所謂カールコード)で構成されていてもよい。伸縮電線W1は螺旋状にカールして伸縮自在に形成されており、電源コンセントまでの距離に応じて伸張させた状態で使用できる。   By the way, in 1 A of charging devices of this embodiment, as shown in FIG. 4, the power cable CB1 may be comprised with the expansion-contraction electric wire W1 (so-called curl cord). The expandable electric wire W1 is curled spirally and formed to be stretchable, and can be used in a stretched state according to the distance to the power outlet.
したがって、使用時には電源ケーブルCB1を伸張させることで、縮んだ状態での長さに比べて遠い場所にある外部電源(電源コンセント201)にも電源コネクタCN1が接続可能になる。また不使用時には電源コネクタCN1を外部電源(電源コンセント201)から外して、電源ケーブルCB1を縮んだ状態とすることで、電源ケーブルCB1がコンパクトに纏まり、電源ケーブルCB1の収納スペースが小さくて済む。よって、不使用時に電源ケーブルCB1が邪魔になることがない。尚、図4の形態では電源ケーブルCB1のみが伸縮電線で構成されているが、電源ケーブルCB1の代わりに充電ケーブルCB2が伸縮電線で構成されてもよいし、電源ケーブルCB1と充電ケーブルCB2の両方が伸縮電線で構成されていてもよい。   Accordingly, by extending the power cable CB1 during use, the power connector CN1 can be connected to an external power source (power outlet 201) located far from the length in the contracted state. Further, when not in use, the power supply connector CN1 is disconnected from the external power supply (power outlet 201) and the power supply cable CB1 is contracted, so that the power supply cable CB1 is compactly packed and the storage space for the power supply cable CB1 can be reduced. Therefore, the power cable CB1 does not get in the way when not in use. In FIG. 4, only the power cable CB1 is composed of an extendable electric wire. However, instead of the power cable CB1, the charging cable CB2 may be composed of an extendable electric wire, and both the power cable CB1 and the charging cable CB2 are used. May be composed of an extendable electric wire.
また、本実施形態の充電装置1Aにおいて、図5に示すように、電源ケーブルCB1及び電源コネクタCN1を収納する収納部16が充電装置本体10に設けられていてもよい。収納部16は、前面が開口した箱型であって充電装置本体10の右側面の下部に取り付けられた箱体17と、箱体17の開口縁にヒンジを介して取り付けられた扉18とで構成され、扉18によって箱体17の開口が開閉自在に閉塞される。   Further, in the charging device 1A of the present embodiment, as shown in FIG. 5, the charging device main body 10 may be provided with a storage portion 16 that stores the power cable CB1 and the power connector CN1. The storage unit 16 is a box shape with an open front surface, and is a box body 17 attached to the lower portion of the right side surface of the charging apparatus body 10 and a door 18 attached to the opening edge of the box body 17 via a hinge. The opening of box 17 is closed by door 18 so that opening and closing is possible.
したがって、ユーザは、充電装置1Aを使用しない場合、扉18を開けて箱体17に電源ケーブルCB1及び電源コネクタCN1を収納した後、扉18を閉じておくことで、電源ケーブルCB1及び電源コネクタCN1を収納部16内に保管することができる。また、充電装置1Aを使用する場合、ユーザは扉18を開け、箱体17から電源ケーブルCB1及び電源コネクタCN1を取り出した後、電源ケーブルCB1を例えば電源コンセントに接続することで、充電装置1Aに外部電源を接続できる。   Therefore, when the user does not use the charging device 1A, the user opens the door 18 and stores the power cable CB1 and the power connector CN1 in the box body 17, and then closes the door 18 so that the power cable CB1 and the power connector CN1 are closed. Can be stored in the storage section 16. Further, when using the charging device 1A, the user opens the door 18, takes out the power cable CB1 and the power connector CN1 from the box 17, and then connects the power cable CB1 to, for example, a power outlet so that the charging device 1A can be connected. External power supply can be connected.
このように、電源ケーブルCB1及び電源コネクタCN1を収納する収納部16が充電装置本体10に設けられることによって、不使用時にはユーザが電源ケーブルCB1及び電源コネクタCN1を収納部16内に収納することができる。したがって、不使用時に電源ケーブルCB1及び電源コネクタCN1が邪魔にならず、使い勝手がよい。   As described above, the storage unit 16 that stores the power cable CB1 and the power connector CN1 is provided in the charging apparatus main body 10, so that the user can store the power cable CB1 and the power connector CN1 in the storage unit 16 when not in use. it can. Therefore, when not in use, the power cable CB1 and the power connector CN1 do not get in the way and are easy to use.
また、本実施形態では壁取り付け型の充電装置1Aを例に説明したが、図7に示すようにスタンド型の充電装置1Bでもよい。   In the present embodiment, the wall-mounted charging device 1A has been described as an example. However, as shown in FIG. 7, a stand-type charging device 1B may be used.
充電装置1Bは、地面に自立した状態で設置される充電装置本体20を備えている。充電装置本体20は、基礎に埋設されたアンカーボルト(図示せず)を取付ベース23の挿通孔24に通し、アンカーボルトにナット(図示せず)を締め付けることで、施工場所に固定される。ここにおいて、取付ベース23の挿通孔24などから、充電装置本体20を施工場所に取り付けるための取付部が構成される。   The charging device 1B includes a charging device main body 20 that is installed in a state of being independent on the ground. The charging device body 20 is fixed at a construction site by passing an anchor bolt (not shown) embedded in the foundation through the insertion hole 24 of the mounting base 23 and tightening a nut (not shown) on the anchor bolt. Here, an attachment portion for attaching the charging device main body 20 to the construction site is constituted by the insertion hole 24 of the attachment base 23 and the like.

A charging cable CB2 is led out from an insertion hole provided in the front surface of the charging device main body 20, and a charging connector CN2 is connected to the tip of the charging cable CB2. Further, a power cable CB1 is led out from the lower side of the side surface of the charging device body 20, and a power connector CN1 is connected to the tip of the power cable CB1. The power supply connector CN1 is connected to a connector 203 connected to a power cord 202 from an external power supply, a power outlet provided on the wall of the building, or the like, whereby the charging device 1B is connected to an external power supply.
このように、スタンド型の充電装置1Bが備える電源ケーブルCB1には外部電源に接続するための電源コネクタCN1が結線されているので、特別な技能を持たない一般のユーザでも電源コネクタCN1を外部電源に接続する作業を行うことができる。したがって、一般のユーザでも設置が可能なスタンド型の充電装置1Bを実現することができる。   Thus, since the power supply cable CB1 provided in the stand-type charging device 1B is connected to the power supply connector CN1 for connecting to the external power supply, even a general user who does not have special skills can connect the power supply connector CN1 to the external power supply. Work to connect to. Therefore, the stand-type charging device 1B that can be installed by a general user can be realized.
ところで、スタンド型の充電装置1Bでも、図4で説明したような伸縮電線W1で電源ケーブルCB1及び充電ケーブルCB2の何れか一方、或いは電源ケーブルCB1及び充電ケーブルCB2の両方が構成されていてもよい。電源ケーブルCB1が伸縮電線で構成されていれば、外部電源までの距離に応じて電源ケーブルCB1を伸縮させた状態で使用できる。また、充電ケーブルCB2が伸縮電線で構成されていれば、電動車両までの距離に応じて充電ケーブルCB2を伸縮させた状態で使用できる。また非使用時には電源ケーブルCB1及び充電ケーブルCB2を縮ませることによって、電源ケーブルCB1及び充電ケーブルCB2が嵩張らず、コンパクトに収納することができる。   By the way, also in the stand-type charging apparatus 1B, either the power cable CB1 or the charging cable CB2 or both the power cable CB1 and the charging cable CB2 may be configured by the stretchable electric wire W1 as described in FIG. . If the power cable CB1 is composed of an extendable electric wire, it can be used in a state where the power cable CB1 is expanded and contracted according to the distance to the external power source. Moreover, if charging cable CB2 is comprised with the expansion-contraction electric wire, it can be used in the state which extended charging cable CB2 according to the distance to an electric vehicle. Further, when not in use, the power cable CB1 and the charging cable CB2 are contracted so that the power cable CB1 and the charging cable CB2 are not bulky and can be stored compactly.
また、図8に示すように充電装置本体20の側面に扉21が設けられ、扉21の内側に電源ケーブルCB1及び電源コネクタCN1を収納する収納部22が設けられてもよい。扉21は、その下側縁がヒンジ(図示せず)を介して充電装置本体20に連結されており、その上側部を開閉させることができる。ユーザが扉21を開くと、収納部22が開放されるので、この状態で収納部22から電源ケーブルCB1及び電源コネクタCN1を取り出したり、収納部22に電源ケーブルCB1及び電源コネクタCN1を収納することができる。   Further, as shown in FIG. 8, a door 21 may be provided on the side surface of the charging device main body 20, and a storage portion 22 for storing the power cable CB <b> 1 and the power connector CN <b> 1 may be provided inside the door 21.

ここで、充電装置1Bを用いた電動車両の充電動作について説明する。   Here, the charging operation of the electric vehicle using the charging device 1B will be described.
先ず、商用交流電源から電力供給を受けて電動車両100Bを充電する場合について説明する。ユーザは、充電装置1Bの電源コネクタCN1を商用交流電源の電源コンセントに接続するとともに、充電コネクタCN2を充電対象の電動車両100Bの充電コネクタ103に接続し、設定部9を用いて商用交流電源から電力供給を受ける状態に切り替える。この時、切替部8は、充電制御部2によって、電源ケーブルCB1から入力された交流電力をリレーR1に出力する状態に切り替えられる。充電制御部2が、電動車両100Bから送信された信号に基づいて、リレーR1をオンにすると、商用交流電源から入力される交流電力が電動車両100Bに供給され、電動車両100Bの充放電回路104によってバッテリ102が充電される。充電中は、充電制御部2が充電装置本体20の前面に配置された発光ダイオードLD4を点灯させており、発光ダイオードLD4の点灯により商用交流電源からの電力供給を受けて電動車両100Bを充電中であることをユーザに報知する。充電対象の電動車両100Bにおいてバッテリ102の充電が完了すると、通信回路106から充電装置1Bの通信部6へ充電完了信号が通知される。充電装置1Bの充電制御部2は、通信部6を介して充電完了信号が入力されると、リレーR1をオフにして電動車両100Bへの給電を停止するとともに、発光ダイオードLD4を消灯させ、充電が終了したことをユーザに報知する。   First, the case where the electric vehicle 100B is charged by receiving power from a commercial AC power source will be described. The user connects the power connector CN1 of the charging device 1B to a power outlet of a commercial AC power supply, connects the charging connector CN2 to the charging connector 103 of the electric vehicle 100B to be charged, and uses the setting unit 9 to switch from the commercial AC power supply. Switch to receiving power. At this time, the switching unit 8 is switched by the charging control unit 2 to a state in which the AC power input from the power cable CB1 is output to the relay R1. When the charging control unit 2 turns on the relay R1 based on the signal transmitted from the electric vehicle 100B, AC power input from the commercial AC power supply is supplied to the electric vehicle 100B, and the charge / discharge circuit 104 of the electric vehicle 100B is supplied. Thus, the battery 102 is charged. During charging, the charging control unit 2 turns on the light emitting diode LD4 disposed on the front surface of the charging device body 20, and the electric vehicle 100B is being charged by receiving power supply from a commercial AC power source by turning on the light emitting diode LD4. This is notified to the user. When charging of the battery 102 is completed in the electric vehicle 100B to be charged, a charging completion signal is notified from the communication circuit 106 to the communication unit 6 of the charging device 1B.

First, the user connects the power connector CN3 of the charging apparatus 1B to the charging connector 103 of the electric vehicle 100A as the power supply source, and connects the charging connector CN2 to the charging connector 103 of the electric vehicle 100B as the power supply destination. After the connection of the charging connector CN2 and the power supply connector CN3, the user switches to a state of receiving power supply from the electric vehicle 100A using the setting unit 9. At this time, the switching unit 8 is switched by the charging control unit 2 to a state in which the DC power input from the power cable CB3 is output to the DC / AC conversion unit 7. And when the signal which notifies charge start is transmitted from the electric vehicle 100B of a charge destination and this signal is input into the charge control part 2 via the communication part 6, the charge control part 2 will be supplied from the communication part 6 to the electric power supply source. A signal for starting discharge is transmitted to the electric vehicle 100A. Further, the charging control unit 2 turns on the relay R1 and starts the DC / AC conversion operation by the DC / AC conversion unit 7. At this time, in the electric vehicle 100A as the supply source, the charge / discharge control circuit 105 causes the charge / discharge circuit 104 to perform a discharge operation based on the signal input from the charging device 1B, and the charge / discharge circuit 104 is discharged from the battery 102. DC power is output to the charging device 1B. In charging apparatus 1B, switching unit 8 outputs DC power supplied from electric vehicle 100A to DC / AC conversion unit 7, and after this DC power is converted into AC by DC / AC conversion unit 7, relay R1 is switched on. To be supplied to the electric vehicle 100B to be charged. The battery 102 is charged by the charge / discharge circuit 104 in the electric vehicle 100B to be charged. During charging, the charging control unit 2 turns on the light emitting diode LD5 disposed on the front surface of the charging device body 20, and the electric vehicle 100B is charged by receiving power supply from the electric vehicle 100A by turning on the light emitting diode LD5. Inform the user that it is inside. Thereafter, when charging of the battery 102 is completed in the electric vehicle 100B to be charged, a communication completion signal is notified from the communication circuit 106 to the communication unit 6. When a charging completion signal is input from the communication unit 6, the charging control unit 2 of the charging device 1 </ b> B turns off the relay R <b> 1 to stop the power supply to the electric vehicle 100 </ b> B and from the communication unit 6 to the electric vehicle 100 </ b> A that is the supply source.
