　本発明の実施形態として示す電動車両充電管理装置は、例えば図１に示すように構成される。図１は、本発明の実施の形態に係る電動車両充電管理装置の構成を示すブロック図である。また、図２は、本発明の実施の形態に係る電動車両充電管理装置の構成の一例を説明するブロック図である。この電動車両充電管理装置は、電動車両ＥＶが走行時に二酸化炭素（ＣＯ２）を排出しないものの、実際には系統電源から充電する際に、発電時にＣＯ２を排出して発電された電力を利用している点に着目し、電動車両ＥＶの充電のために給電されている電力が、非化石エネルギーを用いて（つまり、ＣＯ２を排出せずに）発電された電力であるか、または、非化石エネルギーとは異なる化石エネルギーを用いて（つまり、ＣＯ２を排出して）発電された電力であるかを通知して、管理する。電動車両充電管理装置は、非化石エネルギーを用いて発電された電力（以下、非化石電力ともいう）で電動車両ＥＶに充電した場合には、非化石電力での充電量をカウントするためのカウンタ値を加算し、化石エネルギーを用いて発電された電力（以下、化石電力ともいう）で電動車両ＥＶに充電した場合には、当該カウンタ値を加算しない。これにより、電動車両充電管理装置は、蓄電池５１に充電されている非化石電力の量をカウントして、電動車両ＥＶの利用において、どの程度（例えば、期間または走行距離等）非化石電力を利用できているかを数値化する。 An electric vehicle charging management device shown as an embodiment of the present invention is configured, for example, as shown in FIG. FIG. 1 is a block diagram showing the configuration of an electric vehicle charging management device according to an embodiment of the present invention. Moreover, FIG. 2 is a block diagram illustrating an example of the configuration of the electric vehicle charging management device according to the embodiment of the present invention. This electric vehicle charging management device does not emit carbon dioxide (CO 2 ) when the electric vehicle EV is running, but actually uses the power generated by emitting CO 2 during power generation when charging from the grid power supply. The power supplied for charging the electric vehicle EV is power generated using non-fossil energy (that is, without emitting CO2 ), or It is notified whether the electric power is generated using fossil energy different from non-fossil energy (that is, by emitting CO 2 ), and is managed. When the electric vehicle EV is charged with electric power generated using non-fossil energy (hereinafter also referred to as non-fossil electric power), the electric vehicle charging management device has a counter for counting the amount of charge with the non-fossil electric power. When the electric vehicle EV is charged with electric power generated using fossil energy (hereinafter also referred to as fossil electric power), the counter value is not added. As a result, the electric vehicle charging management device counts the amount of non-fossil electric power charged in the storage battery 51, and determines how much non-fossil electric power is used in the use of the electric vehicle EV (for example, period or travel distance). Quantify what is done.
　この電動車両充電管理装置は、電力系統２０に接続された住宅１０と電動車両ＥＶとを電力線で接続可能としたものである。住宅１０には、分電盤１１、複数の負荷機器１２（１～ｎ）、充放電コンバータ１３、電力管理装置１４（制御部）、通信部１５、及び、発電装置１６が配置されている。 This electric vehicle charging management device enables connection between the house 10 connected to the electric power system 20 and the electric vehicle EV via a power line. In the house 10, a distribution board 11, a plurality of load devices 12 (1 to n), a charge/discharge converter 13, a power management device 14 (controller), a communication unit 15, and a power generation device 16 are arranged.
　充放電コンバータ１３は、電力ケーブルを介して電動車両ＥＶと電気的に接続される。充放電コンバータ１３は、電動車両ＥＶと接続された場合に、電力管理装置１４の制御に従って、当該電動車両ＥＶとの間で電力を授受する。充放電コンバータ１３は、ＤＣ－ＤＣ変換回路と、ＡＣ－ＤＣ変換回路とを含む。充放電コンバータ１３は、住宅１０に適した電圧と電動車両ＥＶの蓄電池５１に適した電圧との間でＡＣ／ＤＣ変換を行う。例えば、住宅１０に適した電圧は１００Ｖの交流電圧である。例えば、電動車両ＥＶにおける蓄電池５１の充放電に適した電圧は３００Ｖ～４００Ｖの直流電圧である。 The charge/discharge converter 13 is electrically connected to the electric vehicle EV via a power cable. When connected to the electric vehicle EV, the charge/discharge converter 13 exchanges electric power with the electric vehicle EV under the control of the power management device 14 . Charge/discharge converter 13 includes a DC-DC conversion circuit and an AC-DC conversion circuit. The charge/discharge converter 13 performs AC/DC conversion between a voltage suitable for the house 10 and a voltage suitable for the storage battery 51 of the electric vehicle EV. For example, a suitable voltage for the house 10 is 100V AC voltage. For example, a DC voltage of 300V to 400V is suitable for charging and discharging the storage battery 51 in the electric vehicle EV.
　分電盤１１は、負荷機器１２、充放電コンバータ１３、発電装置１６、及び、電力系統２０と接続されている。分電盤１１は、分岐回路やリレー、ブレーカ等を備える。分電盤１１は、電力系統２０から供給された系統電力を分岐して、負荷機器１２に供給する。また、分電盤１１は、電動車両ＥＶの蓄電池５１に対して充電を行う場合に、充放電コンバータ１３に電力を供給する。更に、分電盤１１は、電動車両ＥＶの蓄電池５１から放電された電力が充放電コンバータ１３を介して供給された場合、当該蓄電池５１から放電された電力を負荷機器１２等に分岐する。更に、分電盤１１は、発電装置１６によって発電電力が生成された場合に、当該発電電力を負荷機器１２や充放電コンバータ１３に分岐することができる。なお、分電盤１１は、発電装置１６による発電電力を電力系統２０に対して供給できてもよく、できなくてもよい。 The distribution board 11 is connected to the load equipment 12 , the charge/discharge converter 13 , the generator 16 , and the power system 20 . The distribution board 11 includes branch circuits, relays, breakers, and the like. The distribution board 11 branches the system power supplied from the power system 20 and supplies the branched power to the load devices 12 . Moreover, the distribution board 11 supplies electric power to the charging/discharging converter 13 when charging the storage battery 51 of the electric vehicle EV. Further, when power discharged from the storage battery 51 of the electric vehicle EV is supplied via the charge/discharge converter 13, the distribution board 11 branches the power discharged from the storage battery 51 to the load devices 12 and the like. Furthermore, when the power generator 16 generates power, the distribution board 11 can branch the power to the load device 12 and the charge/discharge converter 13 . Note that the distribution board 11 may or may not supply the power generated by the power generation device 16 to the power system 20 .
　負荷機器１２は、住宅１０における各種の家電機器である。 The load devices 12 are various home appliances in the house 10 .
　通信部１５は、電力管理装置１４及び電動車両ＥＶと接続される。通信部１５は、電動車両ＥＶと住宅１０との間で情報を送受信する。ここでは、通信部１５は、図２に示されるように電動車両ＥＶに搭載された充電量積算部５０に対して、電動車両ＥＶに給電されている電力が非化石電力であるか否かを通知する（通知部の一例）。より具体的には、通信部１５は、電動車両ＥＶに給電されている電力のうち、非化石電力が含まれる割合を通知するように構成されている。例えば、図中の電力系統２０の先には、電力供給会社が運用している変電所等の電力供給施設が存在し、ユーザは、この電力供給会社と契約することにより、電力供給施設から電力の供給が行われる。 The communication unit 15 is connected to the power management device 14 and the electric vehicle EV. The communication unit 15 transmits and receives information between the electric vehicle EV and the house 10 . Here, the communication unit 15, as shown in FIG. 2, asks the charge amount accumulating unit 50 mounted on the electric vehicle EV whether or not the electric power supplied to the electric vehicle EV is non-fossil electric power. Notify (an example of the notifier). More specifically, the communication unit 15 is configured to notify the proportion of non-fossil power included in the power supplied to the electric vehicle EV. For example, beyond the power system 20 in the figure, there is a power supply facility such as a substation operated by a power supply company. is supplied.
　電力供給会社によっては、自社が供給する電力のうち、何割を非化石電力で供給し、何割を化石電力で供給しているかを開示している場合がある。本実施の形態では、供給される電力に、上記の非化石電力で供給される割合を充電量積算部５０に通知する。これにより、電力系統２０から供給される電力により電動車両ＥＶを充電した場合にも、含まれる非化石電力の割合に応じた充電量のカウントが可能となる。なお、上記のような電力と当該電力を発電するために用いられた発電の態様（非化石エネルギーを用いたか、化石エネルギーを用いたか）とは、紐づけられた状態で改ざん不可能に管理されていてもよい。このような管理方法として、ブロックチェーン技術が適用されてもよい。 Some electric power supply companies disclose what percentage of the electricity they supply is supplied by non-fossil electricity and what percentage is supplied by fossil electricity. In the present embodiment, the charge amount integration unit 50 is notified of the ratio of non-fossil power to the supplied power. As a result, even when the electric vehicle EV is charged with the power supplied from the power system 20, it is possible to count the charging amount according to the ratio of the included non-fossil power. In addition, the above-mentioned electric power and the form of power generation used to generate the electric power (whether non-fossil energy was used or fossil energy was used) are managed in a linked state so that they cannot be falsified. may be Blockchain technology may be applied as such a management method.
　また、この構成は必須ではなく、電力系統２０から供給される電力を全て化石電力として取り扱ってもよい。その際は、通信部１５は、単に、電力系統２０からの電力であるか、または、発電装置１６等の非化石電力であるかのみを通知すればよい。 Also, this configuration is not essential, and all the power supplied from the power system 20 may be treated as fossil power. In that case, the communication unit 15 may simply notify whether the power is from the power grid 20 or non-fossil power such as the power generation device 16 .
　電力管理装置１４は、負荷機器１２と発電装置１６と電力系統２０と電動車両ＥＶとの間で授受される電力を管理する。特に、この電力管理装置１４は、電動車両ＥＶに給電されている電力として非化石電力（非化石電力が１０割）が給電中であること、化石電力（化石電力が１０割）が給電中であること、または、非化石電力及び化石電力の給電中の割合（非化石電力ｍ割、化石電力（１０－ｍ）割）を検知する（検知部の一例）。 The power management device 14 manages power exchanged between the load device 12, the power generation device 16, the power system 20, and the electric vehicle EV. In particular, the power management device 14 confirms that non-fossil power (100% non-fossil power) is being supplied as the power being supplied to the electric vehicle EV, and that fossil power (100% fossil power) is being supplied. Detects the presence or the ratio of non-fossil power and fossil power being supplied (non-fossil power m percent, fossil power (10-m) percent) (an example of a detection unit).
　図３は、本発明の実施の形態に係る電力分配システムにおける電力分配を示すブロック図である。図３に示すように、住宅１０には、系統電源２０ａと接続され、当該系統電源２０ａから供給された系統電力Ｐ１が供給される。この系統電力Ｐ１は、分電盤１１により分岐して、負荷機器１２用の電力Ｐ２と、電動車両ＥＶ用の電力Ｐ３となる。このような系統電源２０ａから供給された電力は、電力系統２０の稼働によって二酸化炭素（ＣＯ２）が生じているので、カウントされない。また、住宅１０には、蓄電池が備えられている場合がある。このような蓄電池から電動車両ＥＶへと供給される電力には、非化石電力と化石電力とが混在している可能性が高いため、化石電力として取り扱う。ただし、蓄電池に蓄電される非化石電力と化石電力との割合を検知し、記憶する構成が備えられる場合には、このような割合が用いられてもよい。 FIG. 3 is a block diagram showing power distribution in the power distribution system according to the embodiment of the invention. As shown in FIG. 3, the house 10 is connected to a system power supply 20a and supplied with system power P1 supplied from the system power supply 20a. This system power P1 is branched by the distribution board 11 to become power P2 for the load device 12 and power P3 for the electric vehicle EV. Electric power supplied from the grid power supply 20a is not counted because carbon dioxide (CO 2 ) is generated by the operation of the power grid 20 . Moreover, the house 10 may be equipped with a storage battery. The electric power supplied from such a storage battery to the electric vehicle EV is highly likely to contain a mixture of non-fossil electric power and fossil electric power, and is treated as fossil electric power. However, such a ratio may be used when the ratio of non-fossil electric power and fossil electric power stored in the storage battery is detected and stored.
　住宅１０の発電装置１６の発電電力は、分電盤１１により分岐し、負荷機器１２用の発電電力Ｐ４と、電動車両ＥＶ用の電力Ｐ５となる。この発電装置１６により発電した電力は、その電力生成によってＣＯ２が発生されず、カウンタ値の加算が行われる。 The power generated by the power generation device 16 of the house 10 is branched by the distribution board 11 into power P4 for the load device 12 and power P5 for the electric vehicle EV. The power generated by the power generation device 16 does not generate CO 2 due to the power generation, and the counter value is added.
　また、発電装置１６の発電電力の一部電力Ｐ６は、分電盤１１から分岐して、住宅１０から電力系統２０へ供給（売電）可能である。 Also, a part of the power P6 of the power generated by the power generator 16 can be branched from the distribution board 11 and supplied (sold) from the house 10 to the power system 20.
　更に、電動車両ＥＶから住宅１０の負荷機器１２への放電電力Ｐ７は、非化石電力を電動車両ＥＶで「走行のために」利用するという観点では、当該非化石電力を消費してはいないため、カウンタ値を減算しない。これはつまり、一度電動車両ＥＶの蓄電池を経由してはいるものの、発電装置１６などから供給された電力が負荷機器１２で消費される発電電力Ｐ４と同様のものとして考えられる。一方で、電動車両ＥＶが、例えば、蓄電池５１から車両負荷５３へと電力を給電して、走行のための電力消費を行った場合、蓄電池５１内の非化石電力を電動車両ＥＶで「走行のために」利用するという観点では、当該非化石電力を消費いるため、カウンタ値を減算する。 Further, the discharge power P7 from the electric vehicle EV to the load device 12 of the house 10 does not consume the non-fossil power from the viewpoint of using the non-fossil power "for driving" in the electric vehicle EV. , do not decrement the counter value. In other words, the power supplied from the power generation device 16 or the like, although having once passed through the storage battery of the electric vehicle EV, can be considered to be similar to the generated power P4 consumed by the load device 12 . On the other hand, for example, when the electric vehicle EV supplies electric power from the storage battery 51 to the vehicle load 53 and consumes electric power for running, the non-fossil electric power in the storage battery 51 is From the standpoint of using it for the purpose of consuming the non-fossil power, the counter value is decremented.
　このような電動車両充電管理装置は、住宅１０と電動車両ＥＶとの間で授受される電力を管理することによって、当該授受される電力に応じた電動車両ＥＶで消費される非化石電力のカウンタ値を調整する。充電量積算部５０は、例えば、住宅１０の充放電コンバータ１３と電動車両ＥＶとの間で需給される電力を計測してもよいし、電動車両ＥＶ内で蓄電池５１に需給される電力を計測してもよい。 Such an electric vehicle charging management device manages the electric power exchanged between the house 10 and the electric vehicle EV, thereby providing a counter for the non-fossil electric power consumed by the electric vehicle EV according to the exchanged electric power. adjust the value. The charge amount integrating unit 50 may, for example, measure power supplied and demanded between the charge/discharge converter 13 of the house 10 and the electric vehicle EV, or measure power supplied and demanded to the storage battery 51 in the electric vehicle EV. You may
　このような電動車両充電管理装置における動作を図４～図６を用いて説明する。 The operation of such an electric vehicle charging management device will be explained using FIGS. 4 to 6. FIG.
　図４は、本発明の実施の形態に係る電動車両充電管理装置の動作例を示すフローチャートである。図４に示すように、まず、通信部１５から、充電量積算部５０に対して、電動車両に給電されている電力が非化石エネルギーを用いて発電された電力であるか否かに関する通知を受信する（Ｓ１０１）。通信部１５及び充電量積算部５０は、この通知の有無によって、電動車両ＥＶに供給されている電力が化石電力であるか否かを判定する（Ｓ１０２）。つまり、ステップＳ１０１及びステップＳ１０２は、通知を受信するか否かの１つのステップとみなすこともできる。 FIG. 4 is a flow chart showing an operation example of the electric vehicle charging management device according to the embodiment of the present invention. As shown in FIG. 4, first, the communication unit 15 notifies the charge amount accumulating unit 50 whether or not the electric power supplied to the electric vehicle is electric power generated using non-fossil energy. Receive (S101). The communication unit 15 and the charge amount accumulating unit 50 determine whether or not the power supplied to the electric vehicle EV is fossil power based on the presence or absence of this notification (S102). In other words, steps S101 and S102 can also be regarded as one step for determining whether or not to receive the notification.
　そして、充電量積算部５０は、通知が受信されたときに、電動車両ＥＶに対して供給されている電力を非化石電力であるとしてカウンタ値を加算する。このカウンタ値は、以下のようにして消費されて減算される。電動車両ＥＶが充電を完了して走行を開始した場合（Ｓ１０４でＹｅｓ）、充電量積算部５０は、消費された充電電力に応じた割合でカウンタ値を減算する（Ｓ１０５）一方で、電動車両ＥＶが走行することなく、蓄電池５１の充電電力が減少した場合、走行して消費されたのではないと判定され（Ｓ１０４でＮｏ）、住宅１０に電力を供給することで充電電力を消費したのか否かを判定する（Ｓ１０６）。 Then, when the notification is received, the charge amount accumulating unit 50 determines that the electric power supplied to the electric vehicle EV is non-fossil electric power and adds the counter value. This counter value is consumed and decremented as follows. When the electric vehicle EV completes charging and starts running (Yes in S104), the charge amount integration unit 50 subtracts the counter value at a rate corresponding to the consumed charge power (S105). When the charging power of the storage battery 51 decreases without the EV running, it is determined that the charging power was not consumed while running (No in S104), and whether the charging power was consumed by supplying power to the house 10. It is determined whether or not (S106).
　充電量積算部５０は、住宅１０に電力を供給して充電電力を消費したと判定した場合（Ｓ１０６でＮｏ）、カウンタ値を加算も減算もせずに処理を終了する。なお、充電量積算部５０は、充電電力を走行に消費したのではなく（Ｓ１０４でＮｏ）、住宅１０に供給して消費したのでもないと判定した場合（Ｓ１０６でＮｏ）、つまり、蓄電池５１の充電電力が消費されていない場合、何らかの消費が発生するまでステップＳ１０４及びステップＳ１０６の判定を繰り返す。 When it is determined that charging power is consumed by supplying power to the house 10 (No in S106), the charging amount integrating section 50 terminates the process without adding or subtracting the counter value. Note that when the charge amount accumulating unit 50 determines that the charge power is not consumed for traveling (No in S104) and is not consumed by being supplied to the house 10 (No in S106), that is, the storage battery 51 charge power is not consumed, the determinations in steps S104 and S106 are repeated until some consumption occurs.
　図５は、本発明の実施の形態に係る電動車両充電管理装置の化石電力の算出について説明する図である。図５では、ある状況における蓄電池５１に充電されている全充電量と、その際のカウンタ値に対応する充電量（つまり、カウンタ値から逆算された非化石電力による充電量）とを示している。この場合、電力系統２０からの化石電力によって電動車両ＥＶの蓄電池５１を充電したことで、カウンタ値に対応する充電量よりも多くの電力が充電された状態になっている。全充電量と、カウンタ値に対応する充電量との差分の充電量は図示するように、化石電力によって充電された充電量であるといえる。このような化石電力による充電が行われた状況で、差分を埋めるようにカウンタ値を増加させる方法について以下に述べる。 FIG. 5 is a diagram explaining calculation of fossil power by the electric vehicle charging management device according to the embodiment of the present invention. FIG. 5 shows the total amount of charge charged in the storage battery 51 in a certain situation and the amount of charge corresponding to the counter value at that time (that is, the amount of charge by non-fossil power calculated backward from the counter value). . In this case, by charging the storage battery 51 of the electric vehicle EV with fossil power from the power system 20, the amount of power charged is greater than the amount of charge corresponding to the counter value. As shown in the figure, the difference between the total charge amount and the charge amount corresponding to the counter value can be said to be the charge amount charged by fossil power. A method of increasing the counter value so as to make up for the difference in such a situation where charging with fossil power is performed will be described below.
　本実施の形態では、化石電力を非化石電力として消費するための消費権（言い換えると、化石エネルギーを非化石エネルギーとして消費するための消費権）をユーザが購入し、これを適用することで、購入量（つまりユーザの所有量）に応じた化石電力を非化石電力として消費することができる。図６は、本発明の実施の形態に係る電動車両充電管理装置の化石電力の非化石電力化の動作例を示すフローチャートである。図６に示すように、まず、ユーザは、携帯端末等を利用して、消費権の購入を行う。そしてこのような消費権を、電力管理装置１４などに登録することで、ユーザが購入した分の、すなわち、ユーザが所有する消費権の所有量を登録することができる。なお、上記の消費権は、一般的な通貨と引き換えに購入することで入手できるが、例えば、発電装置１６によって発電された電力を売電することで、対価として、一般的な通貨を得る代わりに入手できてもよい。この場合、購入などの操作をせずとも、売電量に応じた消費権が、電力管理装置１４などに自動的に登録される。 In the present embodiment, the user purchases a consumption right for consuming fossil power as non-fossil power (in other words, a consumption right for consuming fossil energy as non-fossil energy), and by applying this, Fossil power can be consumed as non-fossil power in accordance with the purchased amount (that is, the amount owned by the user). FIG. 6 is a flow chart showing an operation example of non-fossil power conversion from fossil power by the electric vehicle charging management device according to the embodiment of the present invention. As shown in FIG. 6, first, the user purchases a consumption right using a portable terminal or the like. By registering such consumption rights in the power management device 14 or the like, it is possible to register the amount purchased by the user, that is, the amount of consumption rights owned by the user. The above consumption rights can be obtained by purchasing them in exchange for common currency. may be available at In this case, the consumption right corresponding to the amount of power sold is automatically registered in the power management device 14 or the like without performing an operation such as purchase.
　通信部１５は、このような消費権の所有量を電力量に換算した消費可能充電量を算出して、これを充電量積算部５０に通知する。充電量積算部５０は、消費可能充電量の通知を受信する（Ｓ２０１）。充電量積算部５０は蓄電池５１に充電されている全充電量と、その時点でのカウンタ値に対応する充電量との差分を算出する（Ｓ２０２）。 The communication unit 15 calculates the consumable charge amount by converting the owned amount of such consumption rights into electric energy, and notifies the charge amount integration unit 50 of this. The charge amount accumulating unit 50 receives the notification of the consumable charge amount (S201). The charge amount integrating unit 50 calculates the difference between the total charge amount of the storage battery 51 and the charge amount corresponding to the counter value at that time (S202).
　そして、充電量積算部５０は、算出した差分と、受信した通知に基づく消費可能充電量とを比較して、算出した差分を最大限縮小するように、消費可能充電量を用いてカウンタ値を加算する。例えば、差分が消費可能充電量より大きい場合（Ｓ２０３でＮｏ）、消費可能充電量を全て利用して、消費可能充電量に応じたカウンタ値を加算する（Ｓ２０４）。また、例えば、差分が消費可能充電量以下の場合（Ｓ２０３でＹｅｓ）、消費可能充電量の一部を利用して、差分を０にするように差分に応じてカウンタ値を加算する（Ｓ２０５）。そして、充電量積算部５０は、利用した分の消費可能充電量を通信部１５へと通知する。通信部は、消費可能充電量のうち、カウンタ値の加算のために利用された分を差し引いて、その時点の消費権の所有量を算出して、電力管理装置１４に再登録する。なお、この例からわかるように、蓄電池５１に充電されている充電量とカウンタ値に対応する充電量とに差が生じる場合がある。 Then, the charge amount accumulating unit 50 compares the calculated difference with the consumable charge amount based on the received notification, and calculates the counter value using the consumable charge amount so as to reduce the calculated difference as much as possible. to add. For example, if the difference is greater than the consumable charge amount (No in S203), the entire consumable charge amount is used and a counter value corresponding to the consumable charge amount is added (S204). Further, for example, if the difference is equal to or less than the consumable charge amount (Yes in S203), a part of the consumable charge amount is used to add the counter value according to the difference so as to make the difference 0 (S205). . Then, the charge amount accumulating unit 50 notifies the communication unit 15 of the consumable charge amount used. The communication unit subtracts the amount used for adding the counter value from the consumable charge amount, calculates the amount of consumption right owned at that time, and re-registers it in the power management device 14 . As can be seen from this example, there may be a difference between the amount of charge in the storage battery 51 and the amount of charge corresponding to the counter value.
　場合によっては、化石電力ばかりを利用して蓄電池５１に充電しながら、電動車両ＥＶの走行でのみ（車両負荷５３に大部分を給電して）電力を利用していると、カウンタ値が負の数値になることがある。ただし、このような負の数値を管理する必要がない場合（例えば、単に電動車両ＥＶで非化石電力をどの程度利用できているかを数値化する場合等）、カウンタ値を０以上の値となるように制限してもよい。このため、充電量積算部５０は、カウンタ値が負の値になった際に、この負の値を０に引き上げるための数値を加算してもよい。 In some cases, if only fossil power is used to charge the storage battery 51 and power is used only for running the electric vehicle EV (by supplying most of the power to the vehicle load 53), the counter value becomes negative. It can be numeric. However, when there is no need to manage such negative numbers (for example, when simply quantifying how much non-fossil power can be used in an electric vehicle EV), the counter value is set to 0 or more. can be restricted to Therefore, when the counter value becomes a negative value, the charge amount accumulating unit 50 may add a numerical value for raising this negative value to zero.
　以上のように、本実施の形態に係る電動車両充電管理装置は、電動車両ＥＶに充電されている電力のうち、非化石電力を用いて充電された電力をカウンタ値として管理することができる。このため、ユーザがどのような電力を用いて電気自動車を利用しているのかをより適切に管理することができる。 As described above, the electric vehicle charging management device according to the present embodiment can manage electric power charged using non-fossil electric power among the electric power charged in the electric vehicle EV as a counter value. Therefore, it is possible to more appropriately manage what kind of power the user uses to use the electric vehicle.

　このような電動車両充電管理装置によれば、通知部（通信部１５）が通知した、電動車両ＥＶに給電されている電力が非化石エネルギーを用いて発電された電力であるか否かに応じて、電動車両ＥＶに給電されている電力の充電量をカウントすることができる。そして、カウンタ値は、充電された電力を消費することで減算される。このようにして、充電量のカウンタ値によって、電動車両ＥＶに充電されている電力がどのようにして発電された電力であるか（非化石エネルギーを用いて発電された電力であるか否か）を数値化することができる。よって、どのような電力を用いて電動車両ＥＶを利用しているのかをより適切に管理することが可能となる。 According to such an electric vehicle charging management device, according to whether or not the electric power supplied to the electric vehicle EV notified by the notification unit (communication unit 15) is electric power generated using non-fossil energy. , the charging amount of electric power supplied to the electric vehicle EV can be counted. The counter value is then decremented by consuming the charged power. In this way, the counter value of the charge amount indicates how the electric power charged in the electric vehicle EV is generated (whether or not the electric power is generated using non-fossil energy). can be quantified. Therefore, it becomes possible to more appropriately manage what kind of electric power is used to use the electric vehicle EV.
　また、例えば、第２態様における電動車両充電管理装置は、充電量積算部５０が、電力消費が、電動車両ＥＶの外部の負荷への電力供給である場合、充電量のカウンタ値を減算せず、電力消費が、電動車両ＥＶの走行のための電力消費である場合、充電量のカウンタ値を減算する、第１態様に記載の電動車両充電管理装置である。 Further, for example, in the electric vehicle charge management device according to the second aspect, the charge amount accumulating unit 50 does not subtract the counter value of the charge amount when the power consumption is power supply to a load external to the electric vehicle EV. , the electric vehicle charge management device according to the first aspect, wherein the counter value of the charge amount is subtracted when the electric power consumption is the electric power consumption for running the electric vehicle EV.
　これによれば、電動車両ＥＶの外部の負荷（例えば、負荷機器１２）への電力供給のために電力消費を行った場合、電動車両ＥＶに充電されている非化石エネルギーを用いて発電された電力分の充電量を電動車両ＥＶで消費してはいないとみなし得る。このため、このような電力消費に対するカウンタ値の減算を行わないようにして、カウンタ値の減少が、電動車両ＥＶの走行のために消費された分の充電量を示すようにできる。 According to this, when power is consumed to supply power to a load (for example, the load device 12) external to the electric vehicle EV, power is generated using the non-fossil energy charged in the electric vehicle EV. It can be considered that the electric vehicle EV does not consume the charging amount for the electric power. Therefore, the counter value is not decremented with respect to such power consumption, and the decrease in the counter value can indicate the amount of charge consumed for running the electric vehicle EV.
　また、例えば、第３態様における電動車両充電管理装置は、電動車両ＥＶに給電されている電力として非化石エネルギーを用いて発電された電力が給電中であることを検知する検知部（電力管理装置１４）を備える、第１又は第２態様に記載の電動車両充電管理装置である。 Further, for example, the electric vehicle charging management device in the third aspect includes a detection unit (power management device 14), the electric vehicle charging management device according to the first or second aspect.
　これによれば、通知部（通信部１５）は、検知部によって検知された、非化石エネルギーを用いて発電された電力が給電中であることに基づいて通知を行うことができる。 According to this, the notification unit (communication unit 15) can make a notification based on the fact that power generated using non-fossil energy is being supplied, which is detected by the detection unit.
　また、例えば、第４態様における電動車両充電管理装置は、通知部（通信部１５）が、電動車両ＥＶに給電されている電力のうち、非化石エネルギーを用いて発電された電力が含まれる割合を通知し、充電量積算部５０が、電動車両ＥＶに給電されている電力に含まれる非化石エネルギーを用いて発電された電力の割合に応じて充電量のカウンタ値を加算する、第１又は第２態様に記載の電動車両充電管理装置である。 Further, for example, in the electric vehicle charging management device in the fourth aspect, the notification unit (communication unit 15) determines the ratio of electric power generated using non-fossil energy to the electric power supplied to the electric vehicle EV. and the charge amount accumulating unit 50 adds the counter value of the charge amount according to the ratio of the power generated using the non-fossil energy contained in the power supplied to the electric vehicle EV, the first or It is an electric vehicle charging management device according to a second aspect.
　これによれば、電動車両ＥＶに給電されている電力のうち、非化石エネルギーを用いて発電された電力が含まれる割合に応じて、充電量のカウンタ値を加算することができる。 According to this, the counter value of the charge amount can be added according to the ratio of the power generated using non-fossil energy to the power supplied to the electric vehicle EV.
　また、例えば、第５態様における電動車両充電管理装置は、充電量のカウンタ値が、０以上の値である、第１～第４態様のいずれか１態様に記載の電動車両充電管理装置である。 Further, for example, the electric vehicle charging management device according to the fifth aspect is the electric vehicle charging management device according to any one of the first to fourth aspects, wherein the counter value of the charge amount is a value of 0 or more. .
　これによれば、充電量のカウンタ値が負の値になることを回避できる。充電量のカウンタ値が０以下の状態で電動車両ＥＶが走行している場合、非化石エネルギーとは異なるエネルギー（化石エネルギー）を用いて発電された電力で充電された充電量を一定以上利用していると考えられるので、カウンタ値が負の値にならなくとも、カウンタ値が０であれば一定以上の化石エネルギーを用いて発電された電力を電動車両ＥＶの走行に利用していると判断することができる。そのため、「電動車両ＥＶの走行に非化石エネルギーを用いて発電された電力がどの程度利用できているか」の観点では、このような、化石エネルギーを用いて発電された電力が、一定以上のどの程度電動車両ＥＶの走行に利用されているかを評価する必要がない場合があり、０より小さいカウンタ値をカウントしないようにして、処理を簡略化することができる。 According to this, it is possible to avoid that the charge amount counter value becomes a negative value. When the electric vehicle EV is running with the charge amount counter value being 0 or less, the charge amount charged with electric power generated using energy different from non-fossil energy (fossil energy) is used above a certain amount. Therefore, even if the counter value does not become a negative value, if the counter value is 0, it is determined that electric power generated using a certain amount or more of fossil energy is used for running the electric vehicle EV. can do. Therefore, from the perspective of "how much power generated using non-fossil energy is being used for driving electric vehicles EVs," how much power generated using fossil energy is above a certain level? In some cases, it may not be necessary to evaluate whether or not the vehicle is being used to run the electric vehicle EV, and processing can be simplified by not counting counter values less than 0.
　また、例えば、第６態様における電動車両充電管理装置は、通知部（通信部１５）が、非化石エネルギーと異なる化石エネルギーを非化石エネルギーとして消費するための消費権の所有量に応じた消費可能充電量を通知し、充電量積算部５０が、電動車両ＥＶに充電済みの全充電量と、充電量のカウンタ値に対応する充電量との差分の充電量を算出し、差分の充電量のうちの消費可能充電量以下の分の充電量に対応するカウンタ値を充電量のカウンタ値に加算する、第１～第５態様のいずれか１態様に記載の電動車両充電管理装置である。 Further, for example, in the electric vehicle charging management device in the sixth aspect, the notification unit (communication unit 15) can consume fossil energy different from non-fossil energy as non-fossil energy according to the amount of consumption rights owned. The charge amount is notified, and the charge amount integrating unit 50 calculates the charge amount that is the difference between the total charge amount of the electric vehicle EV and the charge amount corresponding to the charge amount counter value, and calculates the difference charge amount. The electric vehicle charge management device according to any one of the first to fifth aspects, wherein a counter value corresponding to the charge amount equal to or less than the consumable charge amount is added to the counter value of the charge amount.
　これによれば、消費権の所有量に応じた消費可能充電量分だけ、差分の充電量を縮小することができる。差分の充電量は、電動車両ＥＶに充電されている充電量のうちの、非化石エネルギーによって発電された電力で充電された充電量ではない分、すなわち、化石エネルギーを利用した充電量に相当する。そして、消費権の所有量に応じてカウンタ値が増加されることで、所有量分だけ化石エネルギーを非化石エネルギーとして消費することができる。 According to this, the differential charge amount can be reduced by the amount of charge that can be consumed according to the amount of consumption rights owned. The differential charge amount corresponds to the charge amount that is not charged with electric power generated by non-fossil energy, in the charge amount that is charged in the electric vehicle EV, that is, the charge amount that uses fossil energy. . By increasing the counter value according to the amount of consumption rights owned, fossil energy can be consumed as non-fossil energy by the amount of the owned amount.
