Description

この発明の実施形態は、電気自動車などの大容量蓄電池への充電器の給電制御に係り、特に商用電源から充電器に給電制御を行う分電盤装置に関する。   Embodiments described herein relate generally to power supply control of a charger to a large-capacity storage battery such as an electric vehicle, and more particularly to a distribution board device that performs power supply control from a commercial power supply to a charger.

従来の住宅用途の大容量充電器給電用の制御装置では、商用電源からプラグインハイブリッド車（ＰＨＶ）や電気自動車（ＥＶ）などの車両蓄電池に充電器から充電する際に、ブレーカを作動させることなく充電が行われている。（例えば、特許文献１）   In a conventional control device for feeding a large-capacity charger for residential use, a breaker is activated when charging a vehicle storage battery such as a plug-in hybrid vehicle (PHV) or an electric vehicle (EV) from a commercial power source. There is no charging. (For example, Patent Document 1)

特開２０１０−１６６７６８公報JP 2010-166768 A

上記した特許文献１の技術は、ブレーカを介して供給される総電流値に基づき、ブレーカの作動が予測される場合に充電処理による充電電流を可変に調整する充電電流調整を行うことにより、ブレーカを作動させることなく充電が行われるものである。   The technique disclosed in Patent Document 1 described above is based on the total current value supplied via the breaker, and performs a charging current adjustment that variably adjusts the charging current due to the charging process when the operation of the breaker is predicted. Charging is performed without operating.

しかしながら、一般に家庭の電力会社との電力使用量契約は、せいぜい４０〜６０アンペア程度である。ＰＨＶやＥＶの走行駆動力を発生するモータに供給される電力を蓄える例えばリチウムイオン電池に充電する容量と時間は、１００Ｖの場合１５Ａで１４時間、２００Ｖの場合１０Ａで７時間程度であり、充電電流は高く、充電時間は長いことになってしまう。家庭内の電流消費が高い時間帯にＰＨＶやＥＶに充電するとなると、電子レンジやエアコンなどの電流消費が高い製品は使用できなくなってしまう。この時間帯のＰＨＶやＥＶへの充電を避け、電流消費が低減する深夜時刻以降に充電を開始すると、必要な
時間までに満充電できない、という問題があった。 However, in general, a power consumption contract with a domestic power company is at most about 40 to 60 amperes. The capacity and time for charging, for example, a lithium ion battery that stores electric power supplied to a motor that generates PHV or EV driving force is 15 hours for 100V, 14 hours for 200V, and 7 hours for 10A for 200V. The current is high and the charging time is long. If the PHV or EV is charged in a time zone where current consumption is high in the home, products with high current consumption such as a microwave oven and an air conditioner cannot be used. There is a problem that if charging is started after midnight when current consumption is reduced and charging to PHV or EV during this time period is avoided, it cannot be fully charged by the required time.

この発明の目的は、家庭内の商用電源を用いて電気自動車などの大容量蓄電池へ充電する場合における不具合を解消することのできる分電盤装置を提供することにある。   An object of the present invention is to provide a distribution board device capable of eliminating problems in charging a large-capacity storage battery such as an electric vehicle using a commercial power source in the home.

上記した課題を解決するために、この発明の分電盤装置に係る一実施形態は、家庭内で必要とする電流消費を最優先にすることにより、ＰＨＶ／ＥＶの充電時に普段使用している電気器具の電源を切るといった不便を回避しながら、余った許容電流内での最大電流でＰＨＶ／ＥＶへの充電を行うことにより、ＰＨＶ／ＥＶへの充電時間も最短時間で充電するようにした。   In order to solve the above-described problems, an embodiment according to the distribution board device of the present invention is usually used at the time of PHV / EV charging by placing highest priority on current consumption required in the home. While avoiding the inconvenience of turning off the power supply of electric appliances, charging to PHV / EV with the maximum current within the surplus allowable current was made to charge PHV / EV in the shortest time. .

また、この発明の分電盤装置に係る他の実施形態は、使用者の電子機器の使用状態に応じて、緊急充電、充電完了時刻優先、家庭内での使用負荷に応じて家庭内給電か充電を適宜優先させ、最低限の主幹ブレーカまたは契約容量であった場合でも、その範囲内で最大限の充電と家庭内給電を行うようにした。   Further, according to another embodiment of the distribution board device of the present invention, the emergency charging, the charging completion time priority is given according to the use state of the user's electronic device, and the domestic power supply is given according to the usage load in the home. Charging was prioritized appropriately so that maximum charging and home power supply were made within that range, even if it was the minimum trunk breaker or contract capacity.

この発明の実施形態によれば、家庭内で必要とする電流消費を優先しながら、ＰＨＶ／ＥＶなどの大容量蓄電池への時間内の充電が可能となる。   According to the embodiment of the present invention, it is possible to charge a large-capacity storage battery such as PHV / EV in time while giving priority to current consumption required in the home.

以下、この発明を実施するための形態について、図面を参照しながら詳細に説明する。   Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the drawings.

図１、図２は、この発明の分電盤装置に関する第１の実施形態について説明するための、図１は概念的な説明を行うための模式図、図２は回路構成図である。   1 and 2 are diagrams for explaining a first embodiment relating to a distribution board device of the present invention. FIG. 1 is a schematic diagram for conceptual explanation, and FIG. 2 is a circuit configuration diagram.

図１および図２において、使用量を監視する機能を有する分電盤１００は、例えば電源ラインＬ１，Ｌ２および中性線Ｎの電路１１で構成される単相３線の商用電源ＡＣに接続される。分電盤１００は、商用電源ＡＣに直接接続される主幹ブレーカ１２と、主幹ブレーカ１２に接続される分岐ブレーカ１３１，１３２，１３３…１３ｎを有する。主幹ブレーカ１２出力側には電流センサ１４１、１４２が介挿接続される。   1 and 2, a distribution board 100 having a function of monitoring usage is connected to a single-phase three-wire commercial power supply AC configured by, for example, power lines L1 and L2 and a neutral line N circuit 11. The The distribution board 100 includes a main breaker 12 directly connected to the commercial power source AC, and branch breakers 131, 132, 133... 13n connected to the main breaker 12. Current sensors 141 and 142 are inserted and connected to the output side of the main breaker 12.

分岐ブレーカ１３１，１３２，１３３…１３ｎの出力は、ＰＨＶ／ＥＶ用コントローラ１６に供給される。コントローラ１６では、商用電源ＡＣに接続されるＰＨＶやＥＶの蓄電池に効率的に充電を促す制御が行われる。また、コントローラ１６は、情報端末機１７の設定により、複数の運転モードに設定可能で、例えば電化製品などを使用しながら、場合によっては電化製品の使用を抑制するピークカットなどを行い、大消費電流の蓄電池への充電をストレスなく充電制御する機能を備える。   The outputs of the branch breakers 131, 132, 133... 13n are supplied to the PHV / EV controller 16. The controller 16 performs control to efficiently charge the PHV or EV storage battery connected to the commercial power supply AC. In addition, the controller 16 can be set to a plurality of operation modes by setting the information terminal 17. For example, while using electrical appliances, the controller 16 performs peak cut to suppress the use of electrical appliances in some cases, and consumes a large amount of power. It has a function to control charging of a current storage battery without stress.

情報端末機１７は、ＰＨＶ／ＥＶ６３の充電に合わせて電化製品などを制御する場合に、コントローラ１６の機器制御端子およびＨＡ端子に接続されたＰＨＶ／ＥＶや電化製品に対し、各種のモード設定や設定内容を確認できる表示器や警報音を発する機能などを備えている。   When the information terminal 17 controls an appliance or the like in accordance with the charging of the PHV / EV 63, the information terminal 17 can set various modes for the PHV / EV and the appliance connected to the device control terminal and the HA terminal of the controller 16. It is equipped with a display that can confirm the settings and a function that emits an alarm sound.

コントローラ１６の制御出力は、例えばエアコン２１、照明２２などの電化製品から構成される第１負荷２００に、例えば炊飯器３１、床暖房３２などの電化製品から構成される第２負荷３００に、例えば電磁調理器４１、電子レンジ４２などの電化製品から構成される第３負荷４００にそれぞれ供給される。   The control output of the controller 16 is applied to, for example, a first load 200 composed of electrical appliances such as an air conditioner 21 and a lighting 22, and a second load 300 composed of electrical appliances such as a rice cooker 31 and a floor heater 32, for example. The electric power is supplied to a third load 400 composed of electrical appliances such as an electromagnetic cooker 41 and a microwave oven 42.

分岐ブレーカ１３１の出力は、電磁開閉器５１、電流センサ５２を介して電気給湯器５３に電力を供給する。分岐ブレーカ１３１と電気給湯器５３は第４負荷５００を構成する。電流センサ５２と電気給湯器５３はコンセント５４で接続される。電磁開閉器５１は、コントローラ１６からの制御信号により開閉制御される。   The output of the branch breaker 131 supplies electric power to the electric water heater 53 via the electromagnetic switch 51 and the current sensor 52. The branch breaker 131 and the electric water heater 53 constitute a fourth load 500. The current sensor 52 and the electric water heater 53 are connected by an outlet 54. The electromagnetic switch 51 is controlled to be opened and closed by a control signal from the controller 16.

また、分岐ブレーカ１３２の出力は、電磁開閉器６１、電流センサ６２を介してＰＨＶ／ＥＶ６３の蓄電池に電力を供給する。分岐ブレーカ１３２とＰＨＶ／ＥＶ６３は、第５負荷６００を構成する。電流センサ６２とＰＨＶ／ＥＶ６３はコンセント６４で接続される。電磁開閉器６１は、コントローラ１６からの制御信号により開閉制御される。   The output of the branch breaker 132 supplies power to the storage battery of the PHV / EV 63 via the electromagnetic switch 61 and the current sensor 62. The branch breaker 132 and the PHV / EV 63 constitute a fifth load 600. The current sensor 62 and the PHV / EV 63 are connected by an outlet 64. The electromagnetic switch 61 is controlled to be opened and closed by a control signal from the controller 16.

なお、当然のことながら、電子レンジやエアコンなどの商用電源との接続もコンセントを介して行われるが、ここでは図示と説明は省略する。また、結線状態の図示と説明は省略したが、実際には複数の分岐ブレーカを使い、製品の電力量を勘案しながら、より細かな括りに分岐ブレーカを振り分け、特定のブレーカが作動しないように分配されている。   As a matter of course, connection to a commercial power source such as a microwave oven or an air conditioner is also made through an outlet, but the illustration and description are omitted here. In addition, although illustration and explanation of the connection state have been omitted, in practice, a plurality of branch breakers are used, and the branch breakers are divided into finer groups while taking into consideration the power consumption of the product so that the specific breaker does not operate. Distributed.

次に、図３のフローチャートも参照しながら、図２の構成による第１実施形態の作用について説明する。   Next, the operation of the first embodiment having the configuration of FIG. 2 will be described with reference to the flowchart of FIG.

先ず、コントローラ１６は、主幹ブレーカ１２に流れる電流を電流センサ１４１，１４２で検出し、現在の家庭内の消費電流値Ｉａを算出する（ステップＳ１）。予め記憶された電力会社との電力使用契約の許容電流値ＩｂからステップＳ１で算出された消費電流値Ｉａを差し引いた電流値Ｉｃを算出する（ステップＳ２）。   First, the controller 16 detects the current flowing through the main breaker 12 with the current sensors 141 and 142, and calculates the current consumption current value Ia in the home (step S1). A current value Ic obtained by subtracting the consumption current value Ia calculated in step S1 from the allowable current value Ib of the power usage contract with the power company stored in advance is calculated (step S2).

ステップＳ２において、求められた電流値Ｉｃが、許容電流値Ｉｂをオーバーさせる、すなわち、その時点の消費電流値Ｉａが許容電流値Ｉｂより小さいかを判断し（ステップＳ３）、許容電流値Ｉｂを越えた場合は、ＰＨＶ／ＥＶ用の電磁開閉器６１を開け、ＰＨＶ／ＥＶ６３は非充電とし家庭内給電とする（ステップＳ４）。ステップＳ３において、許容電流値Ｉｂを越えていないと判断した場合は、電磁開閉器６１を閉じて許容電流値Ｉｂから消費電流値Ｉａを差し引いた電流値ＩｃでＰＨＶ／ＥＶ６３に充電を行う（ステップＳ５）。   In step S2, it is determined whether the obtained current value Ic exceeds the allowable current value Ib, that is, whether the current consumption value Ia at that time is smaller than the allowable current value Ib (step S3), and the allowable current value Ib is determined. If exceeded, the PHV / EV electromagnetic switch 61 is opened, and the PHV / EV 63 is uncharged and used for home power supply (step S4). If it is determined in step S3 that the allowable current value Ib is not exceeded, the electromagnetic switch 61 is closed and the PHV / EV 63 is charged with a current value Ic obtained by subtracting the current consumption value Ia from the allowable current value Ib (step S3). S5).

このように、主幹ブレーカ１２の許容電流値Ｉｂから現在の家庭内の消費電流値Ｉａを差し引いた残りを、ＰＨＶ／ＥＶ６３の充電器への供給可能電流とする制御を行ったことにより、主幹ブレーカ１２を通過する電流を、主幹ブレーカ１２の許容電流値内に収め、家庭内停電を防止することが可能となる。また、許容電流値Ｉｂ内であり、ＰＨＶ／ＥＶ６３が充電状態にある場合は、許容電流値Ｉｂから消費電流値Ｉａを差し引いた最大の電流値ＩｃでＰＨＶ／ＥＶ６３の充電が可能となる。電流値Ｉｃは情報端末機１７を操作することにより、任意に選択することで充電時間の調整も可能となる。   As described above, the main breaker 12 is controlled so that the remaining current obtained by subtracting the current consumption current value Ia in the home from the allowable current value Ib of the main breaker 12 can be supplied to the PHV / EV 63 charger. The current passing through 12 is kept within the allowable current value of the main breaker 12, and it is possible to prevent a household power failure. When the PHV / EV 63 is within the allowable current value Ib and the PHV / EV 63 is in the charged state, the PHV / EV 63 can be charged with the maximum current value Ic obtained by subtracting the current consumption value Ia from the allowable current value Ib. The current value Ic can be arbitrarily selected by operating the information terminal 17 to adjust the charging time.

コントローラ１６は、ＰＨＶ／ＥＶ６３に充電中も、電化製品などのスイッチが切られた場合に、使用されていた電化製品などの消費電流も自動的にＰＨＶ／ＥＶ６３に回す制御を行うことで、より一層満充電時間の短縮化を図ることができる。   The controller 16 performs control to automatically turn the current consumption of the electrical appliances used to the PHV / EV 63 when the electrical appliances are switched off while the PHV / EV 63 is being charged. It is possible to further shorten the full charge time.

この実施形態では、家庭内で必要とする電流消費を優先としたことにより、ＰＨＶ／ＥＶの充電時に普段使用している電化製品の電源を切るといった不便を回避しながら、許容電流値から余った分の最大の電流値でＰＨＶ／ＥＶへの充電ができることから、ＰＨＶ／ＥＶに最短時間で充電することが可能となる。   In this embodiment, priority is given to the current consumption required in the home, so that the inconvenience of turning off the electrical appliances that are normally used when charging PHV / EV is avoided, while remaining from the allowable current value. Since the PHV / EV can be charged with the maximum current value of minutes, it is possible to charge the PHV / EV in the shortest time.

図４のフローチャートは、この発明の分電盤装置に関する第２の実施形態について説明するための説明図であり、図２の構成図とともに説明する。この実施形態は、充電完了時刻モードと、ＰＨＶ／ＥＶ充電優先モードおよび家庭内給電優先モードを時間帯区分に設定可能とするものである。   The flowchart of FIG. 4 is explanatory drawing for demonstrating 2nd Embodiment regarding the distribution board apparatus of this invention, and demonstrates with the block diagram of FIG. In this embodiment, the charge completion time mode, the PHV / EV charge priority mode, and the home power supply priority mode can be set to the time zone classification.

図４において、コントローラ１６は、現在の時刻からＰＨＶ／ＥＶ充電優先か家庭内給電優先かを判断する（ステップＳ１）。ステップＳ１でＰＨＶ／ＥＶ充電優先の時刻の場合は、主幹ブレーカ１２に流れる電流を電流センサ１４１，１４２で検出し、現在の家庭内の消費電流値Ｉａを算出する（ステップＳ２）。予め記憶された電力会社との電力使用契約の許容電流値ＩｂからステップＳ１で算出された消費電流値Ｉａを差し引いた電流値Ｉｃを求め（ステップＳ３）、許容電流値Ｉｂ内にあるかを判断する（ステップＳ４）。  In FIG. 4, the controller 16 determines whether the PHV / EV charging priority or the home power supply priority is given from the current time (step S1). If the PHV / EV charging priority time is determined in step S1, the current flowing through the main breaker 12 is detected by the current sensors 141 and 142, and the current consumption current value Ia in the home is calculated (step S2). A current value Ic obtained by subtracting the consumption current value Ia calculated in step S1 from the allowable current value Ib of the power usage contract with the power company stored in advance is obtained (step S3), and it is determined whether it is within the allowable current value Ib. (Step S4).

ステップＳ４において、許容電流値Ｉｂ以内でないと判断した場合は第１段として予め定めた第２負荷３００への電力の供給を停止し（ステップＳ５）、ステップＳ６に進む。ステップＳ６では、ステップＳ５において電力の供給を停止したことにより、電流値Ｉｃが必要な電流値かを判断する。ステップＳ６で必要とする電流値Ｉｃでないと判断した場合は、ステップＳ４に戻る。ステップＳ６で緊急充電に可能な電流値と判断した場合は、ステップＳ３で求められた電流値Ｉｃに基づく充電時間を演算し、情報端末機１７に充電完了時刻を表示し（ステップＳ７）、ＰＨＶ／ＥＶ６３に充電を行う（ステップＳ８）。   If it is determined in step S4 that the current is not within the allowable current value Ib, the supply of power to the second load 300 determined in advance as the first stage is stopped (step S5), and the process proceeds to step S6. In step S6, it is determined whether the current value Ic is a necessary current value by stopping the supply of power in step S5. If it is determined in step S6 that the current value Ic is not necessary, the process returns to step S4. If it is determined in step S6 that the current value can be used for emergency charging, the charging time based on the current value Ic obtained in step S3 is calculated, and the charging completion time is displayed on the information terminal 17 (step S7). / EV63 is charged (step S8).

ステップＳ４において、許容電流値Ｉｂ以内と判断した場合は、許容電流値Ｉｂが緊急充電に十分な電流値Ｉｃかを判断する（ステップＳ９）。ステップＳ９において十分な電流値Ｉｃと判断した場合は、ステップＳ７に進み充電完了時刻を表示し、ＰＨＶ／ＥＶ６３に充電を行う。   If it is determined in step S4 that the current value is within the allowable current value Ib, it is determined whether the current value Ib is sufficient for emergency charging (step S9). If it is determined in step S9 that the current value Ic is sufficient, the process proceeds to step S7, the charging completion time is displayed, and the PHV / EV 63 is charged.

ステップＳ９において緊急充電できる電流値Ｉｃではないと判断した場合は、第２段階として予め定めた第３負荷４００への電力供給を停止し（ステップＳ１０）、ステップＳ１１に進む。ステップＳ１１では、電流値Ｉｃが緊急充電に必要な電流値であると判断した場合、ステップＳ７において充電完了時刻を表示し、ＰＨＶ／ＥＶ６３に充電を行う。ステップＳ１１で十分でないと判断した場合は、指定時刻内に充電できない旨の警報や表示などを用いて使用者に報知する（ステップＳ１２）。   If it is determined in step S9 that the current value Ic cannot be urgently charged, the power supply to the third load 400 determined in advance as the second stage is stopped (step S10), and the process proceeds to step S11. If it is determined in step S11 that the current value Ic is a current value necessary for emergency charging, the charging completion time is displayed in step S7, and the PHV / EV 63 is charged. If it is determined in step S11 that the charging is not sufficient, the user is notified using an alarm or display indicating that charging cannot be performed within the designated time (step S12).

なお、ステップＳ１で家庭内給電優先時刻と判断した場合のコントローラ１６は、電磁開閉器６１を開いてＰＨＶ／ＥＶ６３への電力供給を停止し、家庭内の給電を優先する状態に設定する。   Note that the controller 16 when it is determined in step S1 that the power supply priority time is in the home, opens the electromagnetic switch 61, stops the power supply to the PHV / EV 63, and sets the home power supply priority.

この実施形態では、充電完了時刻を認識できるとともに、時間帯により家庭内給電とＰＨＶ／ＥＶの充電の優先を区別したことで、家庭内給電時間帯におけるＰＨＶ／ＥＶ充電による電化製品使用不可の不都合な状態を解消することができる。   In this embodiment, the charging completion time can be recognized, and the priority of home power supply and PHV / EV charging is distinguished according to the time zone, so that it is not possible to use the appliance due to PHV / EV charging in the home power supply time zone. Can be resolved.

図５のフローチャートは、この発明の分電盤装置に関する第３の実施形態について説明するための説明図であり、図５について図２とともに説明する。この実施形態は、ＰＨＶ／ＥＶの充電完了時刻設定モードと使用の電化製品などの負荷の種類により優先順位付けする優先負荷モードとの複合モードを備えたものである。   The flowchart of FIG. 5 is explanatory drawing for demonstrating 3rd Embodiment regarding the distribution board apparatus of this invention, and FIG. 5 is demonstrated with FIG. This embodiment includes a combined mode of a PHV / EV charging completion time setting mode and a priority load mode that prioritizes according to the type of load such as the appliance used.

図５において、情報端末機１７が充電完了時刻モードとともに、ＰＨＶ／ＥＶ充電優先モードおよび家庭内給電優先モードに設定されると（ステップＳ１）、コントローラ１６は、主幹ブレーカ１２に流れる電流を電流センサ１４１，１４２で検出し、現在の家庭内の消費電流値Ｉａを算出する（ステップＳ２）。予め記憶された電力会社との電力使用契約の許容電流値ＩｂからステップＳ２で求められた消費電流値Ｉａを差し引いた電流値Ｉｃを求め（ステップＳ３）、求められた電流値ＩｃはステップＳ１で設定された時刻内で充電可能かを判断する（ステップＳ４）。   In FIG. 5, when the information terminal 17 is set to the PHV / EV charge priority mode and the home power supply priority mode together with the charge completion time mode (step S1), the controller 16 detects the current flowing through the main breaker 12 as a current sensor. 141 and 142, and the current consumption current value Ia in the home is calculated (step S2). A current value Ic obtained by subtracting the consumption current value Ia obtained in step S2 from the allowable current value Ib of the power usage contract with the power company stored in advance is obtained (step S3), and the obtained current value Ic is obtained in step S1. It is determined whether charging is possible within the set time (step S4).

ステップＳ４において、電流値Ｉｃが許容電流値Ｉｂ以内でないと判断した場合は、第１段階として例えば第２負荷３００への電力の供給を停止し（ステップＳ５）、ステップＳ６に進む。ステップＳ６では、ステップＳ５において電力の供給を停止したことにより、電流値Ｉｃが充電完了時刻内の充電が可能かの演算を行い判断する。ステップＳ６で充電完了時刻内とする必要な電流値Ｉｃでないと判断した場合は、ステップＳ４に戻る。ステップＳ６で、充電完了時刻内の電流値Ｉｃと判断した場合はＰＨＶ／ＥＶ６３の充電を開始する（ステップＳ７）。   If it is determined in step S4 that the current value Ic is not within the allowable current value Ib, as a first stage, for example, the supply of power to the second load 300 is stopped (step S5), and the process proceeds to step S6. In step S6, it is determined by calculating whether the current value Ic can be charged within the charging completion time because the supply of power is stopped in step S5. If it is determined in step S6 that the current value Ic is not within the charge completion time, the process returns to step S4. If it is determined in step S6 that the current value Ic is within the charging completion time, charging of the PHV / EV 63 is started (step S7).

ステップＳ４において、充電完了時刻内の電流値Ｉｃであると判断するとステップＳ８に進み、ステップＳ８において、電流値Ｉｃで充電完了時刻内の充電が可能かの演算を行い判断する。可能と判断した場合は、ステップＳ７に進みＰＨＶ／ＥＶ６３の充電を開始する。   If it is determined in step S4 that the current value Ic is within the charge completion time, the process proceeds to step S8. In step S8, it is determined whether the current value Ic can be charged within the charge completion time. If it is determined that it is possible, the process proceeds to step S7 and charging of the PHV / EV 63 is started.

ステップＳ８において充電完了時刻内の充電を完了できる電流値Ｉｃでないと判断すると、第２段階として例えば第３負荷４００への電力供給を停止し（ステップＳ９）、ステップＳ１０に進む。ステップＳ１０では、ステップＳ９において第３負荷４００への電力の供給を停止したことにより電流値Ｉｃが上昇し、上昇後の電流値Ｉｃが充電完了時刻内の充電が可能かの演算を行い判断する。ステップＳ１０において充電完了時刻内とする必要な電流値Ｉｃであると判断した場合は、ステップＳ７に進みＰＨＶ／ＥＶ６３の充電を開始する。ステップＳ１０において充電完了時刻内とする必要な電流値Ｉｃでないと判断した場合は、指定の時刻内の充電は完了できない警報や表示などを用いて使用者に報知する（ステップＳ１１）。   If it is determined in step S8 that the current value Ic cannot be charged within the charging completion time, for example, the power supply to the third load 400 is stopped as the second stage (step S9), and the process proceeds to step S10. In step S10, the current value Ic increases due to the stop of power supply to the third load 400 in step S9, and the current value Ic after the increase is calculated to determine whether charging within the charging completion time is possible. . If it is determined in step S10 that the current value Ic is within the charge completion time, the process proceeds to step S7 and charging of the PHV / EV 63 is started. If it is determined in step S10 that the current value Ic is not required within the charging completion time, the user is notified using an alarm or display that cannot be charged within the designated time (step S11).

なお、ステップＳ１１において、さらに他の電化製品への電力の供給を停止する第３段階の充電時刻内に電流値Ｉｃを確保することも考えられる。ステップＳ１１の報知には、実際に充電が完了する時間の表示や音声によるものが考えられる。また、緊急の場合は充電完了時刻の設定を通常の充電完了時間よりも短い時間に設定することにより充電時間を短くすることもできる。さらに、家庭内の給電が優先時間であっても、情報端末機の操作により充電を優先させることも可能である。   In step S11, it is also conceivable to secure the current value Ic within the third stage charging time when the supply of power to other electrical appliances is stopped. The notification in step S11 may be a display of the time when charging is actually completed or a sound. In an emergency, the charging time can be shortened by setting the charging completion time to a time shorter than the normal charging completion time. Furthermore, even when power supply in the home is a priority time, it is possible to prioritize charging by operating the information terminal.

また、負荷である電化製品などの複数種類を一括りとしたが、電化製品などの個別に優先順位を付けて、優先順位に従いＰＨＶ／ＥＶに充電するための消費電流をこまめに調整することもできる。   Also, although multiple types of electrical appliances that are loads are grouped together, it is possible to prioritize electrical appliances individually and adjust the current consumption for charging to PHV / EV according to the priorities. it can.

この実施形態では、使用者の電子機器の使用状態に応じて充電完了時刻優先、家庭内での使用負荷に応じて家庭内給電か充電を適宜優先させるようにした。これにより、最低限の主幹ブレーカまたは契約容量であった場合でも、その範囲内で最大限の充電と家庭内給電を行うことができる。   In this embodiment, priority is given to charging completion time according to the usage state of the user's electronic device, and domestic power feeding or charging is appropriately prioritized according to the usage load in the home. Thereby, even if it is the minimum trunk breaker or contract capacity, the maximum charge and domestic power supply can be performed within the range.

いくつかの実施形態を説明したが、これらの実施形態は、例として提示したものであり、発明の範囲を限定することは意図していない。これら新規な実施形態は、その他の様々な形態で実施されることが可能であり、発明の要旨を逸脱しない範囲で、種々の省略、置き換え、変更を行うことができる。これら実施形態やその変形は、発明の範囲や要旨に含まれるとともに、特許請求の範囲に記載された発明とその均等の範囲に含まれる。   Although several embodiments have been described, these embodiments have been presented by way of example and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention.
