　以上のように本実施の形態によれば、カメラ部１１によって撮影された電動車両３を含む画像に基づいて、画像認識部１２によって、電動車両３の位置が充放電位置であるか否かが判断されるとともに、電動車両３の充放電が許可可能か否かが判断される。画像認識部１２によって、電動車両３の位置が充放電位置であると判断されるとともに、電動車両３の充放電が許可可能であると判断されると、コネクタロック制御部１５によって、充放電用ケーブル２と電動車両３との接続を固定するように充放電コネクタラッチ部２４が制御される。また充放電制御部１４によって、電力変換部１３による電動車両３の充放電が許可される。 As described above, according to the present embodiment, whether or not the position of the electric vehicle 3 is the charge / discharge position is determined by the image recognition unit 12 based on the image including the electric vehicle 3 photographed by the camera unit 11. It is determined whether or not charging / discharging of electric vehicle 3 can be permitted. When it is determined by the image recognition unit 12 that the position of the electric vehicle 3 is the charge / discharge position and it is determined that charging / discharging of the electric vehicle 3 can be permitted, the connector lock control unit 15 performs charging / discharging. The charge / discharge connector latch portion 24 is controlled so as to fix the connection between the cable 2 and the electric vehicle 3. In addition, charging / discharging of the electric vehicle 3 by the power conversion unit 13 is permitted by the charging / discharging control unit 14.
　これによって、たとえば、充放電中に誤って電動車両３が移動したときに、充放電用ケーブル２が外れて、充放電用ケーブル２が破損することを抑制することができる。したがって、充放電用ケーブル２の破損に伴う電流の漏えいを防ぐことができるので、ユーザの感電の危険性を回避することができる。また、充放電が許可可能でない電動車両３の充放電を回避することができるので、たとえば、電力の盗難を防ぐことができる。 Thus, for example, when the electric vehicle 3 is accidentally moved during charging / discharging, it is possible to prevent the charging / discharging cable 2 from being disconnected and the charging / discharging cable 2 from being damaged. Therefore, current leakage due to breakage of the charging / discharging cable 2 can be prevented, and the risk of electric shock for the user can be avoided. Moreover, since charging / discharging of the electric vehicle 3 which cannot permit charging / discharging can be avoided, theft of electric power can be prevented, for example.

The monitor unit 51 displays an image photographed by the camera unit 11 based on the data received by the image receiving unit 53.
　ユーザインタフェイス部５２は、カメラ部１１によって撮影された画像に基づいて、充放電を許可する電動車両３を登録可能に構成される。ユーザは、ユーザインタフェイス部５２を操作することによって、カメラ部１１で撮影された画像に基づいて、充放電を許可する電動車両３を登録することができる。 The user interface unit 52 is configured to be able to register the electric vehicle 3 that permits charging / discharging based on the image taken by the camera unit 11. The user can register the electric vehicle 3 that permits charging / discharging based on the image captured by the camera unit 11 by operating the user interface unit 52.
　ユーザが充電を許可する電動車両３を登録する場合、ユーザは、まず、カメラ部１１が撮影できる範囲に、登録したい電動車両３を停止した後、ユーザインタフェイス部５２を用いて、充電を許可する電動車両３を登録する。このとき、画像認識部１２は、電動車両３のナンバープレート、電動車両３の色、電動車両３の形状などによって、登録された電動車両３を記録する。 When the user registers the electric vehicle 3 for which charging is permitted, the user first stops charging the electric vehicle 3 to be registered within a range that can be photographed by the camera unit 11 and then permits charging using the user interface unit 52.

　また、ユーザが、複数台の電動車両３を所有する場合は、充電を許可する電動車両として、複数の電動車両３を登録することも可能である。 Further, when the user owns a plurality of electric vehicles 3, it is also possible to register the plurality of electric vehicles 3 as electric vehicles permitting charging.
　図７は、本発明の第２の実施の形態における電力変換装置２０１による電力変換処理の処理手順を示すフローチャートである。図７に示すフローチャートの各処理は、電力変換装置２０１の各部によって実行される。図７に示すフローチャートの処理は、電力変換装置本体１Ａの電源が投入されると開始され、ステップａ１に移行する。図７に示すフローチャートは、前述の図５に示すフローチャートと同様であるので、同一のステップについては同一のステップ番号を付して、共通する説明を省略する。 FIG. 7 is a flowchart showing a processing procedure of power conversion processing by the power conversion device 201 according to the second embodiment of the present invention. Each process of the flowchart illustrated in FIG. 7 is executed by each unit of the power conversion apparatus 201. The process of the flowchart shown in FIG. 7 is started when the power of the power conversion apparatus main body 1A is turned on, and the process proceeds to step a1. Since the flowchart shown in FIG. 7 is the same as the flowchart shown in FIG. 5 described above, the same steps are denoted by the same step numbers and common description is omitted.
　第１の実施の形態と同様にして、ステップａ１およびステップａ２の処理が終了すると、ステップｂ１に移行する。ステップｂ１において、画像認識部１２は、カメラ部１１によって撮影された画像に含まれる電動車両が、ユーザインタフェイス部５２によって登録された電動車両３と同一か否かを判断する。登録された電動車両３と同一であると判断された場合は、ステップａ４に移行し、登録された電動車両３と同一でないと判断された場合は、全ての処理手順を終了する。ステップａ４～ステップａ１０の処理は、第１の実施の形態と同様にして行われる。 In the same manner as in the first embodiment, when the processing of step a1 and step a2 ends, the process proceeds to step b1. In step b <b> 1, the image recognition unit 12 determines whether the electric vehicle included in the image captured by the camera unit 11 is the same as the electric vehicle 3 registered by the user interface unit 52. When it is determined that it is the same as the registered electric vehicle 3, the process proceeds to step a4. When it is determined that it is not the same as the registered electric vehicle 3, all the processing procedures are ended. The processing from step a4 to step a10 is performed in the same manner as in the first embodiment.
　以上のように本実施の形態によれば、画像認識部１２によって、カメラ部１１で撮影された画像に含まれる電動車両が、ユーザインタフェイス部５２によって登録された電動車両３と同一であると判断されると、電動車両３の充放電が許可可能であると判断される。ユーザインタフェイス部５２によって登録された電動車両３と同一でないと判断されると、電動車両３の充放電が許可可能でないと判断される。これによって、登録された電動車両３のみに充放電を許可することができる。したがって、たとえば、意図しない電動車両３への充電を回避することができるので、電力の盗難を防ぐことができる。 As described above, according to the present embodiment, the electric vehicle included in the image captured by the camera unit 11 by the image recognition unit 12 is the same as the electric vehicle 3 registered by the user interface unit 52. If determined, it is determined that charging / discharging of electric vehicle 3 can be permitted. If it is determined that it is not the same as the electric vehicle 3 registered by the user interface unit 52, it is determined that charging / discharging of the electric vehicle 3 cannot be permitted. As a result, only the registered electric vehicle 3 can be charged / discharged. Therefore, for example, unintended charging of the electric vehicle 3 can be avoided, so that power theft can be prevented.
　また本実施の形態では、電力変換装置２０１は、ユーザコントローラ５にモニタ部５１を備える。モニタ部５１を備えることによって、ユーザが電動車両３およびその周辺の状況を監視することができる。したがって、電動車両３の盗難および電動車両３へのいたずらを監視することができるので、防犯性を向上させることができる。 In this embodiment, the power conversion device 201 includes the monitor unit 51 in the user controller 5. By providing the monitor unit 51, the user can monitor the situation of the electric vehicle 3 and its surroundings. Therefore, since theft of the electric vehicle 3 and the mischief to the electric vehicle 3 can be monitored, crime prevention can be improved.
　また、モニタ部５１、またはモニタ部５１を備えるユーザコントローラ５を、住宅内に設置した場合には、ユーザは、住宅内に居ながら、電動車両３およびその周辺の状況を監視し、電動車両３の盗難および電動車両３へのいたずらを監視することができる。したがって、ユーザの利便性を向上させることができる。 Moreover, when the user controller 5 including the monitor unit 51 or the monitor unit 51 is installed in a house, the user monitors the electric vehicle 3 and its surroundings while in the house, and the electric vehicle 3 Theft and mischief to the electric vehicle 3 can be monitored. Therefore, user convenience can be improved.
　＜第３の実施の形態＞
　図８は、本発明の第３の実施の形態における電力変換装置２０２を備える充放電システム１０２の構成を示すブロック図である。本実施の形態では、充放電システム１０２は、電力変換装置２０２および電動車両３を備えて構成される。本実施の形態における充放電システム１０２は、前述の第２の実施の形態における充放電システム１０１と同様の構成であるので、同一の構成については同一の参照符号を付して、共通する説明を省略する。 <Third Embodiment>
FIG. 8 is a block diagram illustrating a configuration of the charge / discharge system 102 including the power conversion device 202 according to the third embodiment of the present invention. In the present embodiment, charging / discharging system 102 includes power conversion device 202 and electric vehicle 3. Since the charge / discharge system 102 in the present embodiment has the same configuration as the charge / discharge system 101 in the second embodiment described above, the same reference numerals are assigned to the same configurations, and a common description is given. Omitted.
　本実施の形態では、電力変換装置２０２は、電力変換装置本体１Ａ、充放電用ケーブル２、ユーザコントローラ通信ケーブル４およびユーザコントローラ５Ａを備えて構成される。 In the present embodiment, the power conversion device 202 includes the power conversion device main body 1A, the charge / discharge cable 2, the user controller communication cable 4, and the user controller 5A.
　本実施の形態におけるユーザコントローラ５Ａは、第２の実施の形態におけるユーザコントローラ５の構成に加えて、ユーザ設定データベース部５６を備える。すなわち、本実施の形態におけるユーザコントローラ５Ａは、モニタ部５１、ユーザインタフェイス部５２、画像受信部５３およびユーザ設定データベース部５６を備える。ユーザ設定データベース部５６は、カメラ部１１によって撮影された画像に含まれる電動車両３毎に、充放電に関する設定値を使用者が設定可能に構成される。 The user controller 5A in the present embodiment includes a user setting database unit 56 in addition to the configuration of the user controller 5 in the second embodiment. That is, the user controller 5A in the present embodiment includes a monitor unit 51, a user interface unit 52, an image receiving unit 53, and a user setting database unit 56. The user setting database unit 56 is configured so that a user can set a setting value related to charging / discharging for each electric vehicle 3 included in an image photographed by the camera unit 11.
　前述のように、Ｖ２Ｈシステムである充放電システム１０２は、ＰＶ装置６によって発電された電力量、宅内負荷９で消費される電力量、および系統電源８から供給される電力の料金に応じて、電動車両３への充電のスケジュール、および電動車両３の蓄電池３２に蓄えられた電力を宅内負荷９に利用するスケジュールを変更して使用することができる。 As described above, the charging / discharging system 102 that is a V2H system depends on the amount of power generated by the PV device 6, the amount of power consumed by the home load 9, and the charge of the power supplied from the system power supply 8. The schedule for charging the electric vehicle 3 and the schedule for using the electric power stored in the storage battery 32 of the electric vehicle 3 for the home load 9 can be changed and used.
　しかし、従来のＶ２Ｈシステムでは、複数台の電動車両を所有するユーザにとって、不便な場合がある。ユーザは、毎日の走行を目的とする通勤用の車両、ならびに宅内負荷および非常時に利用することも想定したＶ２Ｈ用途を主とした車両などの、複数の電動車両を所有することがある。 However, the conventional V2H system may be inconvenient for a user who owns a plurality of electric vehicles. A user may own a plurality of electric vehicles such as a commuter vehicle for daily driving and a vehicle mainly used for V2H intended to be used in a house load and an emergency.
　たとえば、ユーザが、電動車両３の蓄電池３２を安価な深夜電力で充電し、日中は通勤で利用する場合を考える。この場合、電力変換装置２０２は、夜間は系統電源８から供給される電力を電力変換部１３によって充電可能な電力に変換し、充放電用ケーブル２を介して電動車両３の蓄電池３２に充電する。電動車両３は、日中は通勤で利用されるので、充放電用ケーブル２から切り離される。 For example, consider a case where the user charges the storage battery 32 of the electric vehicle 3 with inexpensive late-night power and uses it for commuting during the day. In this case, the power conversion device 202 converts the power supplied from the system power supply 8 into power that can be charged by the power conversion unit 13 at night, and charges the storage battery 32 of the electric vehicle 3 via the charging / discharging cable 2. . Since the electric vehicle 3 is used for commuting during the day, it is disconnected from the charging / discharging cable 2.
　また、たとえば、ユーザが、電動車両３は週末にしか利用せず、電力の自給自足を求める場合を考える。この場合、日中にＰＶ装置６によって発電された電力は、ＰＶパワーコンディショナ７および電力変換部１０３によって充電可能電力に変換され、充放電用ケーブル２を通じて電動車両３の蓄電池３２に充電される。ＰＶ装置６による発電が無い夜間に関しては、電動車両３の蓄電池３２に充電された電力を、分電盤１０を通じて宅内負荷９に供給することによって、系統電源８を可及的に必要としない電力利用が可能となる。 Also, for example, consider a case where the user uses the electric vehicle 3 only on weekends and seeks self-sufficiency of power. In this case, the electric power generated by the PV device 6 during the day is converted into chargeable power by the PV power conditioner 7 and the power conversion unit 103 and charged to the storage battery 32 of the electric vehicle 3 through the charging / discharging cable 2. . At night when there is no power generation by the PV device 6, the power charged in the storage battery 32 of the electric vehicle 3 is supplied to the in-home load 9 through the distribution board 10 so that the power supply 8 does not require as much as possible. It can be used.
　また、ユーザが、電動車両３を近距離しか利用しない場合もある。この場合、電動車両３の蓄電池３２に蓄えられた電力のうち、予め決められた電力量までは宅内負荷９で消費する電力として用い、残りは電動車両３を駆動するための電力として用いるように、蓄電池３２の使用量制限が設けられる。 Also, the user may use the electric vehicle 3 only at a short distance. In this case, out of the electric power stored in the storage battery 32 of the electric vehicle 3, up to a predetermined amount of electric power is used as electric power consumed by the home load 9, and the rest is used as electric power for driving the electric vehicle 3. In addition, a usage limit for the storage battery 32 is provided.
　このように、Ｖ２Ｈシステムとして使用される充放電システム１０２では、ユーザの用途に応じて、様々な利用方法があり、利用方法毎にスケジューリングおよび蓄電電池３２の使用量制限の設定が存在する。これらのスケジューリングおよび蓄電池３２の使用量制限の設定は、ユーザコントローラ５Ａによって制御される。 As described above, in the charge / discharge system 102 used as the V2H system, there are various usage methods depending on the usage of the user, and there are settings for scheduling and usage amount limitation of the storage battery 32 for each usage method. These scheduling and setting of the usage limit of the storage battery 32 are controlled by the user controller 5A.
　前述のようにユーザが車両毎に異なった利用場面を想定している場合、車両毎に、電力変換装置の充放電スケジュール、ならびに電動車両の最大充電率および最大放電率の設定を行うことを望むことがある。すなわち、ユーザが複数の電動車両３を所有しており、電動車両３毎に設定を変えたい場合、ユーザは、電力変換装置本体１Ａに接続された電動車両３毎に、ユーザコントローラ５Ａを利用して、設定を変更する必要がある。したがって、従来のＶ２Ｈシステムでは、車両毎の設定が煩雑であるので、設定の間違いが生じやすく、ユーザにとって不便であるという問題がある。 As described above, when the user assumes different usage scenes for each vehicle, it is desired to set the charging / discharging schedule of the power conversion device and the maximum charging rate and the maximum discharging rate of the electric vehicle for each vehicle. Sometimes. That is, when the user owns a plurality of electric vehicles 3 and wants to change the setting for each electric vehicle 3, the user uses the user controller 5A for each electric vehicle 3 connected to the power converter main body 1A. Change the settings. Therefore, in the conventional V2H system, since the setting for each vehicle is complicated, there is a problem that a setting error is likely to occur, which is inconvenient for the user.
　これに対し、本実施の形態では、複数台の電動車両３を所有するユーザは、カメラ部１１が撮影できる範囲に、登録したい電動車両３を停止して、登録させればよい。具体的には、画像認識部１２が、カメラ部１１によって撮影された画像から、電動車両３のナンバープレート、電動車両３の色、電動車両３の形状などによって、所有する電動車両３を記録する。これによって、ユーザコントローラ５のユーザ設定データベース部５６に電動車両３を登録することができる。 On the other hand, in the present embodiment, the user who owns the plurality of electric vehicles 3 may stop and register the electric vehicle 3 to be registered within the range that the camera unit 11 can shoot. Specifically, the image recognition unit 12 records the owned electric vehicle 3 from the image taken by the camera unit 11 according to the license plate of the electric vehicle 3, the color of the electric vehicle 3, the shape of the electric vehicle 3, and the like. . Thereby, the electric vehicle 3 can be registered in the user setting database unit 56 of the user controller 5.
　ユーザ設定データベース部５６は、登録された電動車両３毎に、スケジューリングおよび電池使用制限設定などの設定値を記録する。これによって、電動車両３が充放電用ケーブル２から一旦切り離されたとしても、再度、充放電用ケーブル２に接続されたときに、接続された電動車両３をカメラ部１１で撮影して、電動車両３の認識を行うことによって、ユーザ設定データベース部５６から所望の設定値を呼び出すことができる。 The user setting database unit 56 records setting values such as scheduling and battery use limit setting for each registered electric vehicle 3. Thus, even if the electric vehicle 3 is once disconnected from the charging / discharging cable 2, when the electric vehicle 3 is connected to the charging / discharging cable 2 again, the connected electric vehicle 3 is photographed by the camera unit 11, By recognizing the vehicle 3, a desired setting value can be called from the user setting database unit 56.
　充放電制御部１４は、カメラ部１１によって撮影された画像に基づいて、その画像に含まれる電動車両３の充放電に関する設定値をユーザ設定データベース部５６から取得し、取得した設定値に基づいて、電動車両３の充放電を制御する。 Based on the image photographed by the camera unit 11, the charge / discharge control unit 14 acquires a setting value related to charging / discharging of the electric vehicle 3 included in the image from the user setting database unit 56, and based on the acquired setting value. The charging / discharging of the electric vehicle 3 is controlled.
　これによって、ユーザが複数台の電動車両３を所有する場合でも、電動車両３のナンバープレート、形状、色などで、ユーザが登録している電動車両３か否かを判断して、ユーザ設定データベース部５６の設定値を参照することができる。この設定値に基づいて、充放電スケジュールおよび電動車両３の蓄電池３２の最大充電率、最大放電率の設定を変更することができる。これによって、接続された電動車両３毎に、ユーザが用途、充放電スケジュール、設定範囲などを変更する必要が無くなるので、ユーザの利便性を向上させることができる。 Accordingly, even when the user owns a plurality of electric vehicles 3, it is determined whether or not the electric vehicle 3 is registered by the user based on the license plate, shape, color, etc. of the electric vehicle 3, and the user setting database. The set value of the unit 56 can be referred to. Based on this set value, the charging / discharging schedule and the setting of the maximum charging rate and the maximum discharging rate of the storage battery 32 of the electric vehicle 3 can be changed. Thereby, since it becomes unnecessary for a user to change a use, a charging / discharging schedule, a setting range, etc. for every connected electric vehicle 3, a user's convenience can be improved.
　＜第４の実施の形態＞
　図９は、本発明の第４の実施の形態における電力変換装置２０３を備える充放電システム１０３の構成を示すブロック図である。本実施の形態では、充放電システム１０３は、電力変換装置２０３および電動車両３を備えて構成される。本実施の形態における充放電システム１０３は、前述の第３の実施の形態における充放電システム１０２と同様の構成であるので、同一の構成については同一の参照符号を付して、共通する説明を省略する。 <Fourth embodiment>
FIG. 9 is a block diagram illustrating a configuration of the charge / discharge system 103 including the power conversion device 203 according to the fourth embodiment of the present invention. In the present embodiment, charging / discharging system 103 includes power conversion device 203 and electric vehicle 3. Since the charge / discharge system 103 in the present embodiment has the same configuration as the charge / discharge system 102 in the third embodiment described above, the same reference numerals are assigned to the same configurations, and a common description is given. Omitted.
　本実施の形態では、電力変換装置２０３は、電力変換装置本体１Ａ、充放電用ケーブル２、ユーザコントローラ通信ケーブル４およびユーザコントローラ５Ｂを備えて構成される。ユーザコントローラ５Ｂは、第３の実施の形態におけるユーザコントローラ５Ａの構成に加えて、画像記録部５４および画像出力端子部５５を備える。すなわち、本実施の形態におけるユーザコントローラ５Ｂは、モニタ部５１、ユーザインタフェイス部５２、画像受信部５３、画像記録部５４、画像出力端子部５５およびユーザ設定データベース部５６を備える。 In the present embodiment, the power conversion device 203 includes a power conversion device main body 1A, a charge / discharge cable 2, a user controller communication cable 4, and a user controller 5B. The user controller 5B includes an image recording unit 54 and an image output terminal unit 55 in addition to the configuration of the user controller 5A in the third embodiment. That is, the user controller 5B in the present embodiment includes a monitor unit 51, a user interface unit 52, an image receiving unit 53, an image recording unit 54, an image output terminal unit 55, and a user setting database unit 56.
　画像記録部５４は、カメラ部１１によって撮影された画像を記録可能に構成される。画像記録部５４は、たとえば、ユーザコントローラ５に内蔵された不揮発性のフラッシュメモリによって実現される。画像記録部５４は、これに限定されず、外付けの記録媒体によって実現されてもよい。画像記録部５４が外付けの記録媒体によって実現される場合、画像記録部５４は、たとえば、ＳＤ（Secure Digital）カードなどの記録媒体が挿入可能なカードスロットによって実現される。 The image recording unit 54 is configured to be able to record an image taken by the camera unit 11. The image recording unit 54 is realized by, for example, a non-volatile flash memory built in the user controller 5. The image recording unit 54 is not limited to this, and may be realized by an external recording medium. When the image recording unit 54 is realized by an external recording medium, the image recording unit 54 is realized by a card slot into which a recording medium such as an SD (Secure Digital) card can be inserted.
　画像出力端子部５５は、カメラ部１１によって撮影された画像を外部に出力可能に構成される。画像出力端子部５５は、画像を出力する端子、より詳細には、外付けのハードディスクに映像を出力して記録するための端子を含んで構成される。具体的には、画像出力端子部５５は、たとえば、ＵＳＢ端子、または、映像を直接出力可能なＡＶ（audiovisual）端子を含んで構成される。 The image output terminal unit 55 is configured to be able to output an image captured by the camera unit 11 to the outside. The image output terminal unit 55 is configured to include a terminal for outputting an image, more specifically, a terminal for outputting and recording a video on an external hard disk. Specifically, the image output terminal unit 55 includes, for example, a USB terminal or an AV (audiovisual) terminal that can directly output video.
　電動車両３の蓄電池３２への充電は、料金が安い深夜電力で行われることが多い。この場合、充放電用ケーブル２は、夜間を通じて電動車両３に繋がれたままとなる。カメラ部１１の映像は、定期的に画像伝送部１６によってユーザコントローラ５Ｂに伝送される。しかし、ユーザが常にモニタ部５１を監視することは困難である。 The charging of the electric vehicle 3 to the storage battery 32 is often carried out with late-night power at a low charge. In this case, the charging / discharging cable 2 remains connected to the electric vehicle 3 throughout the night. The video of the camera unit 11 is periodically transmitted to the user controller 5B by the image transmission unit 16. However, it is difficult for the user to always monitor the monitor unit 51.
　本実施の形態では、ユーザコントローラ５Ｂは、画像記録部５４および画像出力端子部５５を備える。したがって、電力変換装置本体１Ａのカメラ部１１によって撮影された画像は、画像伝送部１６、ユーザコントーラ通信ケーブル４および画像受信部５３を通じて、画像記録部５４に直接記録されるか、または、画像出力端子部５５を通じて外部の記録媒体に記録される。 In the present embodiment, the user controller 5B includes an image recording unit 54 and an image output terminal unit 55. Therefore, an image photographed by the camera unit 11 of the power conversion device main body 1A is directly recorded in the image recording unit 54 through the image transmission unit 16, the user controller communication cable 4, and the image receiving unit 53, or is output as an image. Recording is performed on an external recording medium through the terminal unit 55.
　これによって、時間および、ユーザの在宅、不在に関わらず、電力変換装置２０３および電動車両３の所望の時間帯の画像を確認して、監視することができる。したがって、ユーザの利便性を向上させるとともに、防犯性を向上させることができる。 Thereby, it is possible to confirm and monitor the images of the power converter 203 and the electric vehicle 3 in a desired time zone regardless of the time and the presence or absence of the user. Therefore, the convenience for the user can be improved and the crime prevention can be improved.
