Description

管理装置Management device
　本発明は、ユーザの発電施設から電力システムに供給された供給電力量を管理する管理装置に関する。 The present invention relates to a management device that manages the amount of power supplied from a power generation facility of a user to a power system.
　従来、発電を行うユーザが余剰電力を発生させた場合に、当該余剰電力分の電力を売却せずに、余剰電力分の電力量を管理しておき、後になって当該ユーザが当該電力量を利用できるようにすることが知られている。例えば、特許文献１には、車両の蓄電池から電力システムに送電される電力に対応する電力を、移動先で再充電することが開示されている。 Conventionally, when a user who generates power generates surplus power, the surplus power is not sold but the surplus power is managed, and the user later manages the surplus power. It is known to make available. For example, Patent Document 1 discloses recharging the electric power corresponding to the electric power transmitted from the storage battery of the vehicle to the electric power system at the destination.
特開２０１５－００５２９３号公報JP, 2005-005293, A
　ところで、ユーザが移動先の充電スタンドで充電を行う場合に、充電スタンドにおける利用状況によって充電スタンドや電力システムに対する負担が異なる。充電スタンドにおいて、電力システムから供給される電力により、車両の蓄電池に対して急速充電を直接行う場合、電力システムに対する負荷が急激に上昇してしまう。したがって、充電スタンドの運営者は、電力システムが急激な負荷に対応できるようにするための設備増強を迫られたり、充電スタンドにおいて電力システムに対する負荷を急激に上昇させないようにするための対策を迫られたりすることがある。 By the way, when the user charges at the charging station at the destination, the load on the charging station and the power system varies depending on the usage status at the charging station. In the charging stand, when the storage battery of the vehicle is directly charged rapidly by the electric power supplied from the electric power system, the load on the electric power system is rapidly increased. Therefore, the operator of the charging station is required to reinforce the equipment so that the power system can cope with a sudden load, or take measures to prevent the load on the power system from rapidly increasing at the charging station. There are times when you are caught.
　充電スタンドにおいて、電力システムに対する負荷を急激に上昇させないようにする対策として、バッテリが設けられる場合がある。この場合には、車両の蓄電池に対し、当該バッテリに蓄電されている電力を充電するところ、ユーザの充電状況によってはバッテリの蓄電量が低下し、他のユーザが充電できる量が減ってしまう可能性がある。このため、充電スタンドの運営者がバッテリの容量を大容量にする等の対応を迫られることがあり、運営者に対してさらに負担がかかる可能性がある。したがって、電力システムに送電される電力に対応する電力をそのままユーザに還元させるのではなく、充電スタンドや電力システムに対する負担を考慮して、ユーザに電力を還元させることが好ましい。 -At charging stations, batteries may be installed as a measure to prevent the load on the power system from rising rapidly. In this case, when the storage battery of the vehicle is charged with the electric power stored in the battery, the charged amount of the battery may decrease depending on the charging status of the user, and the charged amount of other users may decrease. There is a nature. For this reason, the operator of the charging station may be forced to take measures such as increasing the capacity of the battery, which may further burden the operator.

　また、記憶部１１には、供給電力量ＤＢ１１１が設けられている。供給電力量ＤＢ１１１は、ユーザの発電施設２から電力システムに供給された供給電力量の少なくとも一部と、ユーザを識別するユーザ識別情報とを関連付けて記憶する。図３は、第１実施形態に係る供給電力量ＤＢ１１１の一例を示す図である。図３に示すように、供給電力量ＤＢ１１１には、ユーザ識別情報と、供給電力量とが関連付けて格納されていることが確認できる。
　また、記憶部１１には、ユーザの発電施設２から電力システムに供給された供給電力量の一部と、ユーザ識別情報とを関連付けて記憶するポイントＤＢ１１２が設けられている。 Further, the storage unit 11 is provided with a supplied power amount DB 111. The supplied power amount DB 111 stores at least a part of the supplied power amount supplied from the power generation facility 2 of the user to the power system and the user identification information for identifying the user in association with each other. FIG. 3 is a diagram illustrating an example of the supplied power amount DB 111 according to the first embodiment. As shown in FIG. 3, it can be confirmed that the user identification information and the supplied power amount are associated and stored in the supplied power amount DB 111.
Further, the storage unit 11 is provided with a point DB 112 that stores a part of the amount of power supplied from the power generation facility 2 of the user to the power system and the user identification information in association with each other.
　制御部１２は、例えばＣＰＵ（Central Processing Unit）である。制御部１２は、記憶部１１に記憶された管理プログラムを実行することにより、記憶制御部１２１、充電結果特定部１２２、決定部１２３、及び更新部１２４として機能する。 The control unit 12 is, for example, a CPU (Central Processing Unit). The control unit 12 functions as the storage control unit 121, the charging result specifying unit 122, the determining unit 123, and the updating unit 124 by executing the management program stored in the storage unit 11.
　記憶制御部１２１は、ユーザの発電施設２から電力システムに供給された供給電力量を、ユーザを識別するユーザ識別情報に関連付けて記憶部１１に記憶させる。具体的には、記憶制御部１２１は、ユーザの発電施設２から電力システムに供給された供給電力量のうち一部の供給電力量を、ユーザ識別情報に関連付けて記憶させる。また、記憶制御部１２１は、供給電力量のうち残りの供給電力量をポイントに変換し、ユーザ識別情報に関連付けて記憶部１１に記憶させる。 The storage control unit 121 stores the amount of power supplied to the power system from the power generation facility 2 of the user in the storage unit 11 in association with the user identification information that identifies the user. Specifically, the storage control unit 121 stores a part of the supplied power amount of the supplied power amount from the power generation facility 2 of the user to the power system in association with the user identification information. Further, the storage control unit 121 converts the remaining power supply amount of the power supply amount into points, and stores the points in the storage unit 11 in association with the user identification information.
　具体的には、まず、記憶制御部１２１は、電力システムに供給された供給電力量に対する、ポイントに変換する供給電力量の割合をユーザから受け付ける。記憶制御部１２１は、発電施設２における発電量のうち、電力量計２５において測定された電力システムに供給される発電量としての供給電力量と、発電施設２のユーザを示すユーザ識別情報とを取得する。 Specifically, first, the storage control unit 121 receives from the user the ratio of the amount of power supplied to the power system to the amount of power supplied to the power system. The storage control unit 121 stores, among the power generation amounts in the power generation facility 2, the supplied power amount as the power generation amount supplied to the power system measured by the watt-hour meter 25 and the user identification information indicating the user of the power generation facility 2. get.
　図４は、発電施設２に設けられている各種装置の関係を示す図である。図４に示すように、発電施設２には、発電装置２１と、パワーコンディショナ２２と、分電盤２３と、複数の電化製品２４と、電力量計２５と、電力量計２６とが設けられている。 FIG. 4 is a diagram showing a relationship among various devices provided in the power generation facility 2. As shown in FIG. 4, the power generation facility 2 is provided with a power generation device 21, a power conditioner 22, a distribution board 23, a plurality of electric appliances 24, a power meter 25, and a power meter 26. Has been.
　パワーコンディショナ２２は、発電装置２１が発電した電力（例えば直流電力）を所定形式の電力（例えば家庭用交流電力）に変換するとともに発電装置２１が発電した電力を測定する。
　分電盤２３は、パワーコンディショナ２２により変換された所定形式の電力を複数の電化製品２４に供給する。 The power conditioner 22 converts the electric power generated by the power generation device 21 (for example, DC power) into electric power of a predetermined format (for example, household AC power) and measures the power generated by the power generation device 21.
The distribution board 23 supplies electric power of a predetermined format converted by the power conditioner 22 to the plurality of electric appliances 24.
　電力量計２５は、上述したように、発電装置２１が発電した電力量のうち、電力システムに供給される供給電力量を測定する。電力量計２５は、通信機能を備えており、所定時間おき（例えば、１日おき）に、供給電力量と、ユーザ識別情報とを管理装置１に送信する。 As described above, the electric energy meter 25 measures the amount of electric power supplied to the electric power system, out of the amount of electric power generated by the power generation device 21. The watt-hour meter 25 has a communication function, and transmits the supplied power amount and the user identification information to the management device 1 every predetermined time (for example, every other day).
　なお、本実施形態では、電力量計２５が、供給電力量と、ユーザ識別情報とを管理装置１に送信したが、これに限らない。例えば、電力量計２５に、管理装置１と通信を行う通信装置を接続させておき、電力量計２５が、当該通信装置を介して供給電力量と、ユーザ識別情報とを管理装置１に送信してもよい。
　電力量計２６は、買電用の電力量計である。電力量計２６は、発電施設２において電力システムから供給された電力（電力会社から購入した電力）を測定する。 In addition, in the present embodiment, the electric energy meter 25 transmits the supplied electric energy and the user identification information to the management device 1, but the present invention is not limited to this. For example, a communication device that communicates with the management device 1 is connected to the power meter 25, and the power meter 25 transmits the supplied power amount and the user identification information to the management device 1 via the communication device. You may.
The electricity meter 26 is an electricity meter for purchasing electricity. The watt-hour meter 26 measures the electric power supplied from the electric power system in the power generation facility 2 (electric power purchased from an electric power company).
　図２に説明を戻す。記憶制御部１２１は、電力量計２５から供給電力量とユーザ識別情報とを受信すると、供給電力量ＤＢ１１１を参照し、受信したユーザ識別情報に関連付けられている供給電力量を特定する。記憶制御部１２１は、ユーザから予め受け付けたポイントに変換する供給電力量の割合に基づいて、電力量計２５から受信した供給電力量のうち、供給電力量ＤＢ１１１の供給電力量に加算する供給電力量を算出する。記憶制御部１２１は、特定した供給電力量に、算出した供給電力量を加算することにより、ユーザの発電施設２から電力システムに供給された供給電力量を、ユーザ識別情報に関連付けて記憶部１１に記憶させる。 Return the explanation to Figure 2. Upon receiving the supplied power amount and the user identification information from the power meter 25, the storage control unit 121 refers to the supplied power amount DB 111 and identifies the supplied power amount associated with the received user identification information. The storage control unit 121 adds the power supply amount of the power supply amount DB 111 out of the power supply amount received from the watt hour meter 25 based on the ratio of the power supply amount to be converted into the points received in advance from the user. Calculate the amount. The storage control unit 121 adds the calculated supplied power amount to the specified supplied power amount to associate the supplied power amount supplied to the power system from the power generation facility 2 of the user with the user identification information, and the storage unit 11 Memorize.
　また、記憶制御部１２１は、供給電力量ＤＢ１１１を更新した後、電力量計２５から、供給電力量ＤＢ１１１の供給電力量に加算されなかった供給電力量を、予め定められたレートに基づいてポイントに変換する。記憶制御部１２１は、ポイントＤＢ１１２を参照し、電力量計２５から受信したユーザ識別情報に関連付けられているポイントを特定する。記憶制御部１２１は、特定したポイントに、供給電力量から変換されたポイントを加算することにより、ポイントＤＢ１１２を更新する。 In addition, after updating the power supply amount DB 111, the storage control unit 121 points the power supply amount that has not been added to the power supply amount of the power supply amount DB 111 from the watt hour meter 25 based on a predetermined rate. Convert to. The storage control unit 121 refers to the point DB 112 and identifies a point associated with the user identification information received from the power meter 25. The storage control unit 121 updates the point DB 112 by adding the points converted from the supplied power amount to the specified points.
　このようにすることで、管理装置１は、供給電力量の一部をポイントに変換するとともに、供給電力量ＤＢ１１１に供給電力量を貯めておくことができる。また、管理装置１は、ユーザから、供給電力量からポイントに変換する割合を受け付け、当該割合に基づいて供給電力量の一部をポイントに変換するので、ユーザの希望に応じて、供給電力量の一部をポイントに変換することができる。ここで、供給電力量から変換されたポイントは、他のポイントに変換できるものであってもよい。また、管理装置１は、供給電力量から当該他のポイントに直接変換してもよい。 By doing so, the management device 1 can convert a part of the supplied power amount into points and store the supplied power amount in the supplied power amount DB 111. Further, the management device 1 accepts from the user a ratio of converting the supplied power amount into points, and converts part of the supplied power amount into points based on the ratio, so that the supplied power amount can be changed according to the user's request. A part of can be converted into points. Here, the points converted from the supplied power amount may be those that can be converted into other points. In addition, the management device 1 may directly convert the supplied power amount to the other point.
　なお、本実施形態では、記憶制御部１２１は、供給電力量と、ユーザ識別情報とを関連付けて管理装置１の供給電力量ＤＢ１１１に記憶させることとしたが、これに限らない。記憶制御部１２１は、ユーザの発電施設２から電力システムに供給された供給電力量と、ユーザを識別するユーザ識別情報とを関連付けた情報を、ブロックチェーンを用いて複数の記憶装置のそれぞれの記憶部に分散して記憶させてもよい。このようにすることで、管理装置１は、ユーザごとの供給電力量の改ざんを抑制し、供給電力量を安全に管理することができる。 In the present embodiment, the storage control unit 121 stores the supplied power amount and the user identification information in the supplied power amount DB 111 of the management device 1 in association with each other, but not limited to this. The storage control unit 121 stores the information in which the amount of power supplied from the power generation facility 2 of the user to the power system and the user identification information for identifying the user are associated with each other in a plurality of storage devices using a block chain. It may be stored in different parts. By doing so, the management device 1 can suppress falsification of the power supply amount for each user and can safely manage the power supply amount.
　充電結果特定部１２２は、ユーザが充電スタンド３において取得した電力量である充電量と、当該充電スタンド３においてユーザが当該電力量を取得したときの充電種別とを示す充電結果を特定する。充電種別は、充電の速さを示す情報である。充電種別としては、例えば、「超急速充電」、「急速充電」、「普通充電」の３つの種別があるものとする。 The charging result identification unit 122 identifies a charging result indicating the amount of charge that is the amount of power that the user acquired at the charging stand 3 and the type of charge when the user acquired the amount of power at the charging stand 3. The charge type is information indicating the charging speed. It is assumed that there are three types of charging, for example, "super-quick charging", "quick charging", and "normal charging".
　例えば、充電設備３１は、表示部を備えており、調整充電量の決定に用いる調整用係数に対応する情報と、充電種別とを関連付けて当該表示部に表示させる。調整充電量の決定に用いる調整用係数に対応する情報は、例えば、単位時間あたりの充電量である単位充電量に対応する調整充電量を示す情報である。充電スタンド３に設けられている充電設備３１は、ユーザが電気自動車Ｃに充電を行う場合に、当該ユーザから充電種別の選択を受け付ける。 For example, the charging facility 31 includes a display unit, and the information corresponding to the adjustment coefficient used to determine the adjusted charge amount and the charge type are associated and displayed on the display unit. The information corresponding to the adjustment coefficient used to determine the adjusted charge amount is, for example, information indicating the adjusted charge amount corresponding to the unit charge amount that is the charge amount per unit time. When the user charges the electric vehicle C, the charging equipment 31 provided in the charging stand 3 receives a selection of the charging type from the user.
　充電結果特定部１２２は、ユーザが、充電スタンド３に設けられている充電設備３１を使用して電気自動車Ｃに充電を行うと、電力量計３３を介して、ユーザ識別情報と、電気自動車Ｃに対する充電量と、充電設備３１が受け付けた充電種別とを示す充電結果情報を取得することにより、充電結果を特定する。 When the user charges the electric vehicle C using the charging equipment 31 provided in the charging stand 3, the charging result specifying unit 122 causes the user identification information and the electric vehicle C via the electric energy meter 33. The charge result is specified by acquiring the charge result information indicating the charge amount for the charge amount and the charge type received by the charging facility 31.
　決定部１２３は、充電結果特定部１２２が特定した充電結果が示す、充電設備３１が受け付けた充電種別を特定する。決定部１２３は、特定した充電種別に基づいて、充電結果特定部１２２が特定した充電結果が示す充電量を調整した調整電力量を決定する。 The deciding unit 123 identifies the charging type received by the charging facility 31 indicated by the charging result identified by the charging result identifying unit 122. The determination unit 123 determines the adjusted power amount in which the charge amount indicated by the charge result identified by the charge result identification unit 122 is adjusted based on the identified charge type.
　例えば、記憶部１１には、充電種別と、単位時間当たりの充電量（例えば、１時間当たりの充電量）を示す情報とを関連付けた充電種別情報が記憶されている。図５は、第１実施形態に係る充電種別情報の一例を示す図である。図５に示されるように、各充電種別に対して、単位時間当たりの充電量と、調整電力量を決定する場合に用いる第１調整用係数とが関連付けられていることが確認できる。また、図５では、単位時間当たりの充電量が相対的に多い充電種別の第１調整用係数が、当該充電量が相対的に少ない充電種別の第１調整用係数よりも小さいことが確認できる。 For example, the storage unit 11 stores charge type information in which a charge type is associated with information indicating a charge amount per unit time (for example, a charge amount per hour). FIG. 5 is a diagram showing an example of the charge type information according to the first embodiment. As shown in FIG. 5, it can be confirmed that the charge amount per unit time and the first adjustment coefficient used when determining the adjusted power amount are associated with each charge type. Further, in FIG. 5, it can be confirmed that the first adjustment coefficient for the charge type having a relatively large charge amount per unit time is smaller than the first adjustment coefficient for the charge type having a relatively small charge amount. ..
　ここで、充電設備３１が、単位時間当たりの充電量が相対的に多い急速充電や超急速充電を許容するためには、バッテリ３２の容量を、単位時間当たりの充電量が相対的に少ない普通充電のみを行う場合に比べて大きくする必要がある。例えば、充電スタンド３において、頻繁に急速充電が行われると、バッテリ３２の蓄電量が恒常的に低下する可能性がある。また、急速充電を行うことにより、バッテリ３２の蓄電量が一時的に低下すると、他のユーザが充電できる量が減ってしまう可能性がある。このため、充電スタンド３の運営者は、急速充電が頻繁に行われる場合には、バッテリ３２の容量を大容量にし、頻繁な急速充電に対応する必要があり、負担がかかるという問題がある。 Here, in order for the charging facility 31 to allow rapid charging or ultra-quick charging in which the charging amount per unit time is relatively large, the capacity of the battery 32 is set to a normal value where the charging amount per unit time is relatively small. It needs to be larger than when charging only. For example, if the charging station 3 is frequently rapidly charged, the amount of electricity stored in the battery 32 may constantly decrease. Further, if the amount of electricity stored in the battery 32 is temporarily reduced by performing the rapid charging, the amount that another user can charge may be reduced. Therefore, the operator of the charging stand 3 needs to increase the capacity of the battery 32 to cope with frequent rapid charging when the rapid charging is frequently performed, which is a burden.
　そこで、決定部１２３は、記憶部１１に記憶されている充電種別情報を参照し、充電結果特定部１２２が特定した充電結果が示す充電種別に対応する単位時間当たりの充電量を特定する。決定部１２３は、特定した当該単位時間当たりの充電量に基づいて、調整充電量を決定する。決定部１２３は、特定した当該単位時間当たりの充電量が多くなればなるほど、充電量に対する調整充電量の割合を大きくすることにより、調整充電量を決定する。例えば、決定部１２３は、充電結果情報が示す充電量に、特定した当該単位時間当たりの充電量に関連付けられている第１調整用係数を乗算することにより調整充電量を決定する。 Therefore, the determining unit 123 refers to the charge type information stored in the storage unit 11 and identifies the charge amount per unit time corresponding to the charge type indicated by the charge result identified by the charge result identifying unit 122. The determining unit 123 determines the adjusted charge amount based on the specified charge amount per unit time. The determination unit 123 determines the adjusted charge amount by increasing the ratio of the adjusted charge amount to the charged amount as the identified charged amount per unit time increases. For example, the determining unit 123 determines the adjusted charge amount by multiplying the charge amount indicated by the charge result information by the first adjustment coefficient associated with the specified charge amount per unit time.
　このようにすることで、管理装置１は、ユーザが急速充電を積極的に利用することを抑制してバッテリ３２の蓄電量が恒常的に低下することを抑制し、他のユーザが充電できる量が減ることを抑制できる。また、管理装置１は、充電スタンド３の運営者がバッテリ３２の容量を大容量にする対応をする可能性を低減させ、充電スタンド３の運営者に負担が発生する可能性を低減することができる。 By doing so, the management device 1 suppresses the user from positively utilizing the rapid charging to suppress the constant decrease in the amount of electricity stored in the battery 32, and the amount that another user can charge. Can be suppressed. In addition, the management device 1 can reduce the possibility that the operator of the charging stand 3 will deal with increasing the capacity of the battery 32 and reduce the possibility that the operator of the charging stand 3 will be burdened. it can.
　なお、本実施形態において、決定部１２３は、単位時間当たりの充電量に基づいて調整充電量を決定することとしたが、これに限らない。決定部１２３は、単位電力当たりの充電時間に基づいて調整充電量を決定してもよい。 In the present embodiment, the determination unit 123 determines the adjusted charge amount based on the charge amount per unit time, but the present invention is not limited to this. The determining unit 123 may determine the adjusted charge amount based on the charging time per unit power.
　ここで、充電設備３１の使用時間が長ければ長いほど、充電に用いる充電設備３１を専有することになり、他のユーザが充電できなくなる可能性がある。そこで、決定部１２３は、充電スタンド３に設けられている充電設備３１を使用したときの充電量が大きくなればなるほど、充電量に対する調整充電量の割合を大きくすることにより、調整充電量を決定してもよい。この場合、充電設備３１は、複数の充電量と、当該充電量に対する調整充電量とを関連付けて表示部に表示させてもよい。 Here, the longer the charging facility 31 is used, the more the charging facility 31 used for charging is occupied, and there is a possibility that other users cannot charge. Therefore, the determining unit 123 determines the adjusted charge amount by increasing the ratio of the adjusted charge amount to the charge amount as the charge amount when the charging facility 31 provided in the charging stand 3 is used increases. You may. In this case, the charging facility 31 may display a plurality of charge amounts and the adjusted charge amount for the charge amounts on the display unit in association with each other.
　記憶部１１には、充電量と、調整電力量を決定する場合に用いる第２調整用係数とが関連付けて記憶されている。第２調整用係数は、例えば、充電量が大きいほど大きな値に設定される。決定部１２３は、記憶部１１を参照し、充電結果特定部１２２が取得した充電結果情報に含まれる充電量に関連付けられている第２調整用係数を特定する。そして、決定部１２３は、充電結果情報が示す充電量に、特定した第２調整用係数を乗算することにより調整充電量を決定する。 The storage unit 11 stores the charge amount and the second adjustment coefficient used when determining the adjustment power amount in association with each other. The second adjustment coefficient is set to a larger value as the charge amount increases, for example. The determination unit 123 refers to the storage unit 11 and identifies the second adjustment coefficient associated with the charge amount included in the charge result information acquired by the charge result identification unit 122. Then, the determining unit 123 determines the adjusted charge amount by multiplying the charge amount indicated by the charge result information by the specified second adjustment coefficient.
　また、充電スタンド３が設置されている施設には、より多くのユーザに充電設備３１を利用させることが好ましい施設もある。例えば、ホテルやレストランといった施設に充電スタンド３が設置されている場合、より多くのユーザに充電設備３１を利用させることが好ましい。そこで、決定部１２３は、充電スタンド３が設置されている施設の種別に基づいて調整充電量を決定してもよい。この場合、充電設備３１は、単位充電量に対応する、施設の種別に基づく調整充電量を表示部に表示させてもよい。 Also, in some facilities where the charging stand 3 is installed, it is preferable to allow more users to use the charging facility 31. For example, when the charging stand 3 is installed in a facility such as a hotel or a restaurant, it is preferable that more users use the charging facility 31. Therefore, the determination unit 123 may determine the adjusted charge amount based on the type of facility where the charging stand 3 is installed. In this case, the charging facility 31 may cause the display unit to display the adjusted charge amount based on the type of facility, which corresponds to the unit charge amount.
　記憶部１１には、施設の種別と、調整電力量を決定する場合に用いる第３調整用係数とが関連付けて記憶されている。第３調整用係数は、例えば、ホテルやレストランといった集客が必要な施設において、その他の施設よりも大きな値に設定することが考えられる。また、同じホテルやレストランであっても、立地や集客の難易度に応じて第３調整係数を変更してもよく（このような変更も施設の種別に基づく調整充電量の決定に含まれる。）、例えば立地が悪く集客難易度の高いホテルやレストランでは、立地が良く集客が容易なホテルやレストランよりも第３調整用係数を大きな値に設定することが考えられる。電力量計３３は、充電スタンド３が設置されている施設の種別を含む充電結果情報を管理装置１に送信する。決定部１２３は、記憶部１１を参照し、充電結果特定部１２２が取得した充電結果情報に含まれる施設の種別に関連付けられている第３調整用係数を特定する。そして、決定部１２３は、充電結果情報が示す充電量に、特定した第３調整用係数を乗算することにより調整充電量を決定する。 In the storage unit 11, the type of facility and the third adjustment coefficient used when determining the adjusted electric energy are stored in association with each other. It is conceivable that the third adjustment coefficient is set to a larger value in facilities, such as hotels and restaurants, that need to attract customers than in other facilities. Even in the same hotel or restaurant, the third adjustment coefficient may be changed according to the location and the difficulty level of attracting customers (such a change is also included in the determination of the adjusted charge amount based on the type of facility). ), for example, in a hotel or restaurant where the location is poor and the difficulty of attracting customers is large, it is conceivable to set the third adjustment coefficient to a larger value than in a hotel or restaurant where the location is good and attracting customers is easy. The watt-hour meter 33 transmits charging result information including the type of facility where the charging stand 3 is installed to the management device 1. The determination unit 123 refers to the storage unit 11 and specifies the third adjustment coefficient associated with the type of facility included in the charging result information acquired by the charging result specifying unit 122. Then, the determining unit 123 determines the adjusted charge amount by multiplying the charge amount indicated by the charge result information by the specified third adjustment coefficient.
　また、充電スタンド３の混雑状況によっては、一人のユーザによる充電設備３１の利用時間を短縮させることが好ましい場合もある。そこで、決定部１２３は、充電スタンド３の混雑状況に基づいて調整充電量を決定してもよい。この場合、充電設備３１は、単位充電量に対応する、現在の混雑状況に基づく調整充電量を表示部に表示させる。 Also, depending on the congestion situation of the charging station 3, it may be preferable to shorten the usage time of the charging facility 31 by one user. Therefore, the determination unit 123 may determine the adjusted charge amount based on the congestion status of the charging stand 3. In this case, the charging facility 31 causes the display unit to display the adjusted charge amount based on the current congestion status, which corresponds to the unit charge amount.
　記憶部１１には、充電スタンド３の混雑状況を示す混雑レベルと、調整電力量を決定する場合に用いる第４調整用係数とが関連付けて記憶されている。第４調整用係数は、例えば、混雑レベルが大きいほど大きな値に設定される。また、電力量計３３は、充電スタンド３の混雑レベルを含む充電結果情報を管理装置１に送信する。決定部１２３は、記憶部１１を参照し、充電結果特定部１２２が取得した充電結果情報に含まれる混雑レベルに関連付けられている第４調整用係数を特定する。そして、決定部１２３は、充電結果情報が示す充電量に、特定した第４調整用係数を乗算することにより調整充電量を決定する。 The storage unit 11 stores the congestion level indicating the congestion status of the charging stand 3 and the fourth adjustment coefficient used when determining the adjustment power amount in association with each other. For example, the fourth adjustment coefficient is set to a larger value as the congestion level is higher. Further, the watt hour meter 33 transmits charging result information including the congestion level of the charging stand 3 to the management device 1. The determination unit 123 refers to the storage unit 11 and specifies the fourth adjustment coefficient associated with the congestion level included in the charging result information acquired by the charging result specifying unit 122. Then, the determining unit 123 determines the adjusted charge amount by multiplying the charge amount indicated by the charge result information by the specified fourth adjustment coefficient.
　このようにすることで、管理装置１は、一人のユーザによる充電設備３１の利用時間が長くなることを抑制し、多くのユーザに充電設備３１を利用させることができる。なお、決定部１２３は、調整充電量を決定する場合に、第１調整用係数、第２調整用係数、第３調整用係数、及び第４調整用係数の少なくともいずれかを用いて調整充電量を決定してもよい。例えば、決定部１２３は、第１調整用係数、第２調整用係数、第３調整用係数、及び第４調整用係数を特定し、これらの調整用係数を充電結果情報が示す充電量に乗算することにより調整充電量を決定してもよい。 By doing so, the management device 1 can prevent a long usage time of the charging equipment 31 by one user and allow many users to use the charging equipment 31. When determining the adjustment charge amount, the determination unit 123 uses at least one of the first adjustment coefficient, the second adjustment coefficient, the third adjustment coefficient, and the fourth adjustment coefficient. May be determined. For example, the determination unit 123 identifies the first adjustment coefficient, the second adjustment coefficient, the third adjustment coefficient, and the fourth adjustment coefficient, and multiplies these adjustment coefficients by the charge amount indicated by the charge result information. The adjusted charge amount may be determined by doing so.
　なお、充電設備３１は、複数の充電種別のそれぞれに対応して充電できるものである。このことから、決定部１２３は、充電結果特定部が特定した充電結果が示す充電種別に基づいて、ユーザが充電スタンド３において使用した充電を行うための設備が単位時間内に充電できる最大電力量を特定してもよい。そして、決定部１２３は、当該単位時間内に充電できる最大電力量に基づいて、調整充電量を決定してもよい。このようにすることで、管理装置１は、高速充電を行うことが可能な充電設備３１において、普通充電が長時間にわたって行われることを抑制することができる。 Note that the charging facility 31 can be charged corresponding to each of a plurality of charging types. From this, the determining unit 123 determines that the maximum amount of power that the facility used by the user for charging in the charging station 3 can charge within a unit time based on the charge type indicated by the charge result identified by the charge result identifying unit. May be specified. Then, the determining unit 123 may determine the adjusted charge amount based on the maximum amount of power that can be charged within the unit time. By doing so, the management device 1 can suppress normal charging from being performed for a long time in the charging facility 31 capable of performing high-speed charging.
　更新部１２４は、決定部１２３が決定した調整充電量を記憶部１１の供給電力量ＤＢ１１１に記憶されている供給電力量から減算することにより、ユーザ識別情報に関連付けて供給電力量ＤＢ１１１に記憶されている供給電力量を更新する。 The updating unit 124 stores the adjusted charge amount determined by the determining unit 123 in the supplied power amount DB 111 in association with the user identification information by subtracting the adjusted charge amount from the supplied power amount stored in the supplied power amount DB 111 of the storage unit 11. The supplied power amount is updated.
　具体的には、更新部１２４は、供給電力量ＤＢ１１１を参照し、充電結果特定部１２２が特定した充電結果が示すユーザ識別情報に関連付けられている供給電力量を特定する。更新部１２４は、特定した供給電力量から、決定部１２３が決定した調整充電量を減算することにより、当該ユーザ識別情報に関連付けて供給電力量ＤＢ１１１に記憶されている供給電力量を更新する。 Specifically, the updating unit 124 refers to the power supply amount DB 111 and identifies the power supply amount associated with the user identification information indicated by the charging result identified by the charging result identifying unit 122. The update unit 124 updates the supplied power amount stored in the supplied power amount DB 111 in association with the user identification information by subtracting the adjusted charge amount determined by the determination unit 123 from the specified supplied power amount.
［管理装置１における処理の流れ］
　続いて、管理装置１における処理の流れについて説明する。図６は、第１実施形態に係る管理装置１における処理の流れの一例を示すフローチャートである。本フローチャートは、所定時間（例えば、１０秒）おきに実行されるものとする。 [Process Flow in Management Device 1]
Next, the flow of processing in the management device 1 will be described. FIG. 6 is a flowchart showing an example of the flow of processing in the management device 1 according to the first embodiment. It is assumed that this flowchart is executed every predetermined time (for example, 10 seconds).
　まず、記憶制御部１２１は、発電施設２から、供給電力量と、ユーザ識別情報とを取得したか否かを判定する（Ｓ１）。記憶制御部１２１は、供給電力量と、ユーザ識別情報とを取得したと判定すると、Ｓ２に処理を移し、供給電力量と、ユーザ識別情報とを取得していないと判定すると、Ｓ３に処理を移す。 First, the storage control unit 121 determines whether or not the power supply amount and the user identification information have been acquired from the power generation facility 2 (S1). When determining that the power supply amount and the user identification information have been acquired, the storage control unit 121 shifts the processing to S2, and when determining that the power supply amount and the user identification information have not been acquired, the storage control unit 121 performs the process to S3.

　Ｓ３において、充電結果特定部１２２は、充電スタンド３から充電結果情報を取得することにより、充電結果を特定したか否かを判定する。充電結果特定部１２２は、充電結果を特定したと判定すると、Ｓ４に処理を移し、充電結果を特定していないと判定すると、本フローチャートに係る処理を終了する。 In S3, the charging result identifying unit 122 determines whether or not the charging result is identified by acquiring the charging result information from the charging stand 3. When determining that the charging result has been specified, the charging result identification unit 122 moves the processing to S4, and when determining that the charging result has not been specified, the processing according to this flowchart ends.
　Ｓ４において、決定部１２３は、充電結果に基づいて調整電力量を決定する。
　Ｓ５において、更新部１２４は、Ｓ４において決定された調整充電量を、供給電力量ＤＢ１１１において充電結果が示すユーザ識別情報に関連付けられている供給電力量から減算することにより、当該供給電力量を更新する。 In S4, the determination unit 123 determines the adjusted power amount based on the charging result.
In S5, the updating unit 124 updates the supply power amount by subtracting the adjusted charge amount determined in S4 from the supply power amount associated with the user identification information indicated by the charging result in the supply power amount DB 111. To do.
［第１実施形態における効果］
　以上説明したように、第１実施形態に係る管理装置１は、ユーザが充電スタンド３において取得した電力量である充電量と、充電スタンド３において電力量を取得したときの充電種別とを示す充電結果を特定し、特定した充電結果が示す充電種別に基づいて、当該充電結果が示す充電量を調整した調整充電量を決定する。そして、管理装置１は、決定した調整充電量を供給電力量ＤＢ１１１に記憶されている供給電力量から減算することにより、ユーザ識別情報に関連付けて供給電力量ＤＢ１１１に記憶されている供給電力量を更新する。 [Effects of First Embodiment]
As described above, the management device 1 according to the first embodiment is a charging device that indicates the amount of charge that is the amount of power that the user has acquired at the charging stand 3 and the type of charge when the amount of power is acquired at the charging stand 3. The result is specified, and the adjusted charge amount obtained by adjusting the charge amount indicated by the charge result is determined based on the charge type indicated by the specified charge result. Then, the management device 1 subtracts the determined adjusted charge amount from the supplied power amount stored in the supplied power amount DB 111 to determine the supplied power amount stored in the supplied power amount DB 111 in association with the user identification information. Update.
　管理装置１がこのように動作することで、充電スタンド３の運営者は、例えば付加価値が高い充電種別のサービスを提供することで利益を増やすことができるので、急速充電をできる環境を提供しやすくなる。充電スタンド３において多様な充電種別に対応するサービスが提供されることで、電力システムに余剰電力を供給したユーザは、ニーズに応じた方法で電気自動車Ｃに充電できるという利益を得ることができる。このように、管理装置１は、電力システムに電力を供給したユーザに対して、ユーザに適した条件で電力を還元することができる。 By operating the management device 1 in this way, the operator of the charging station 3 can increase profits by providing a service of a charging type having a high added value, thus providing an environment in which rapid charging can be performed. It will be easier. By providing services corresponding to various types of charging at the charging stand 3, the user who has supplied the surplus power to the power system can obtain an advantage that the electric vehicle C can be charged by a method according to needs. In this way, the management device 1 can return the power to the user who has supplied the power to the power system under the condition suitable for the user.
　なお、第１実施形態では、充電スタンド３がバッテリ３２を備えている例について説明したが、これに限らず、充電スタンド３はバッテリ３２を設けていなくてもよい。この場合、充電設備３１は、電力システムから供給される電力により、電気自動車Ｃの蓄電池に対して充電を直接行う。管理装置１は、ユーザが充電スタンド３において取得した電力量である充電量を、単位時間当たりの充電量が大きければ大きいほど、調整充電量が大きくなるように調整充電量を決定する。これにより、ユーザが急速充電を頻繁に行うことを抑制し、電力システムに対する負荷が急激に上昇することを抑制することができる。また、本実施形態では、管理装置１が、決定した調整充電量を供給電力量ＤＢ１１１に記憶されている供給電力量から減算することにより、ユーザ識別情報に関連付けて供給電力量ＤＢ１１１に記憶されている供給電力量を更新する例について説明したが、調整充電量に基づいて供給電力量を更新する方法は単純な「減算」のみに限定されない。管理装置１は、他の計算方法による代替又は当該計算方法との組み合わせにより更新を行ってもよい。 Note that, in the first embodiment, an example in which the charging stand 3 includes the battery 32 has been described, but the present invention is not limited to this, and the charging stand 3 may not include the battery 32. In this case, the charging facility 31 directly charges the storage battery of the electric vehicle C with the power supplied from the power system. The management device 1 determines the adjustment charge amount such that the adjustment charge amount increases as the charge amount per unit time, which is the amount of electric power acquired by the user at the charging stand 3, increases. As a result, it is possible to prevent the user from frequently performing rapid charging, and to prevent the load on the power system from rapidly increasing. In addition, in the present embodiment, the management device 1 subtracts the determined adjusted charge amount from the supplied power amount stored in the supplied power amount DB 111 to store it in the supplied power amount DB 111 in association with the user identification information. Although the example of updating the supplied power amount has been described, the method of updating the supplied power amount based on the adjusted charge amount is not limited to simple “subtraction”. The management device 1 may perform the update by substitution with another calculation method or by combination with the calculation method.
＜第２実施形態＞
［充電前に充電種別を特定する］
　続いて、第２実施形態について説明する。充電スタンド３においてユーザが電気自動車Ｃに充電を行う場合、ユーザの予定や電気機器の状況等に基づいて予め充電種別を特定することが好ましい場合がある。例えば、充電スタンド３が設置されている施設におけるユーザの滞在時間が短いと予想される場合に、電気自動車Ｃの蓄電池の残容量が少ないときには、高速充電を行うことが好ましいと考えられる。そこで、第２実施形態に係る管理装置１は、ユーザの予定や電気自動車Ｃの蓄電状況等に基づいて予め充電種別を特定し、当該充電種別に基づく充電を充電スタンド３に指示する点で第１実施形態と異なる。以下に、第２実施形態に係る管理装置１について説明を行う。なお、第１実施形態と同じ部分については適宜説明を省略する。 <Second Embodiment>
[Specify charge type before charging]
Next, the second embodiment will be described. When the user charges the electric vehicle C at the charging stand 3, it may be preferable to specify the charging type in advance based on the user's schedule, the status of the electric device, and the like. For example, when it is expected that the user stays in the facility where the charging station 3 is installed for a short period of time, it is considered preferable to perform high-speed charging when the remaining capacity of the storage battery of the electric vehicle C is small. Therefore, the management device 1 according to the second embodiment specifies the charging type in advance based on the user's schedule, the power storage state of the electric vehicle C, and the like, and instructs the charging station 3 to perform charging based on the charging type. Different from the first embodiment. The management apparatus 1 according to the second embodiment will be described below. The description of the same parts as those in the first embodiment will be appropriately omitted.
　図７は、第２実施形態に係る管理装置１の構成を示す図である。図７に示すように、第２実施形態に係る制御部１２は、充電種別特定部１２５と、指示部１２６とをさらに備える。 FIG. 7 is a diagram showing the configuration of the management device 1 according to the second embodiment. As shown in FIG. 7, the control unit 12 according to the second embodiment further includes a charge type identification unit 125 and an instruction unit 126.
　充電種別特定部１２５は、充電スタンド３においてユーザが取得する電力量の充電先である電気機器としての電気自動車Ｃの蓄電状況を特定し、当該蓄電状況に基づいて充電スタンド３において電気自動車Ｃに充電する電力量を取得する場合の充電種別を特定する。 The charging type identifying unit 125 identifies the power storage state of the electric vehicle C as an electric device that is a charging destination of the amount of power acquired by the user at the charging station 3, and the electric vehicle C is identified at the charging station 3 based on the power storage state. Specify the charging type when acquiring the amount of power to be charged.
　例えば、電気自動車Ｃは、充電スタンド３の充電設備３１と通信を行う通信部と、バッテリとを備えている。充電設備３１は、ユーザから、電気自動車Ｃへの充電開始操作を受け付ける場合に、ユーザ識別情報及び電気自動車Ｃのバッテリの蓄電状況を示す蓄電状況情報を取得する。 For example, the electric vehicle C includes a communication unit that communicates with the charging facility 31 of the charging stand 3 and a battery. When the charging facility 31 receives a charging start operation for the electric vehicle C from the user, the charging facility 31 acquires the user identification information and the storage state information indicating the storage state of the battery of the electric vehicle C.
　例えば、ユーザは、ユーザ識別情報を記憶するカードを所持している。充電設備３１は、電気自動車Ｃと通信を行うことにより蓄電状況情報を取得する取得部と、カードに記憶されているユーザ識別情報を読み取る読取部とを備えている。充電設備３１は、読取部により、当該カードに記憶されているユーザ識別情報を読み取ることにより当該ユーザ識別情報を取得するとともに、取得部により蓄電状況情報を取得する。 For example, the user has a card that stores user identification information. The charging facility 31 includes an acquisition unit that acquires the power storage status information by communicating with the electric vehicle C, and a reading unit that reads the user identification information stored in the card. In the charging facility 31, the reading unit reads the user identification information stored in the card to acquire the user identification information, and the acquisition unit acquires the power storage state information.
　充電設備３１は、ユーザ識別情報と、蓄電状況情報とを取得すると、これらの情報を管理装置１に送信する。管理装置１の充電種別特定部１２５は、充電設備３１から、ユーザ識別情報と、蓄電状況情報とを取得すると、当該蓄電状況情報が示す蓄電状況に基づいて充電種別を特定する。 When the charging facility 31 acquires the user identification information and the power storage status information, the charging equipment 31 transmits these information to the management device 1. When the charging type identifying unit 125 of the management device 1 acquires the user identification information and the storage state information from the charging facility 31, the charging type identifying unit 125 identifies the charging type based on the storage state indicated by the storage state information.
　例えば、充電種別特定部１２５は、蓄電状況が示す蓄電量が所定の閾値未満の場合には、充電種別を急速充電と特定する。また、充電種別特定部１２５は、蓄電状況が示す蓄電量が第１閾値以上の場合には、充電種別を普通充電と特定する。 For example, the charge type identification unit 125 identifies the charge type as quick charge when the amount of charge indicated by the charge state is less than a predetermined threshold. In addition, the charge type identification unit 125 identifies the charge type as normal charge when the amount of stored electricity indicated by the storage state is equal to or greater than the first threshold value.
　なお、充電種別特定部１２５は、ユーザから、充電スタンド３が設置されている施設におけるユーザの滞在時間の予想時間を受け付け、当該予想時間に基づいて当該充電スタンド３において電気機器に充電する電力量を取得する場合の充電種別を特定してもよい。 Note that the charging type identifying unit 125 receives from the user an estimated time of the user's staying time at the facility where the charging stand 3 is installed, and the amount of electric power to charge an electric device in the charging stand 3 based on the estimated time. You may specify the charge type when acquiring.
　この場合、まず、充電設備３１は、電気自動車Ｃへの充電開始操作の受付時に、ユーザ識別情報と、蓄電状況情報とを取得するとともに、ユーザから、充電スタンド３が設置されている施設における滞在時間の予想時間を受け付ける。充電設備３１は、ユーザ識別情報と、蓄電状況情報と、滞在時間の予想時間とを管理装置１に送信する。 In this case, first, the charging facility 31 acquires the user identification information and the power storage state information at the time of accepting the charging start operation for the electric vehicle C, and the user stays at the facility where the charging stand 3 is installed. Accept the expected time. The charging facility 31 transmits the user identification information, the storage state information, and the estimated staying time to the management device 1.
　管理装置１の充電種別特定部１２５は、充電設備３１から、ユーザ識別情報と、蓄電状況情報と、滞在時間の予想時間とを取得すると、当該予想時間と、当該蓄電状況情報が示す蓄電状況とに基づいて、電気自動車Ｃに充電する電力量を取得する場合の充電種別を特定する。 When the charging type identification unit 125 of the management device 1 acquires the user identification information, the power storage status information, and the estimated stay time from the charging equipment 31, the estimated time and the power storage status indicated by the power storage status information are acquired. Based on, the charge type when the amount of electric power charged to the electric vehicle C is acquired is specified.
　例えば、充電種別特定部１２５は、蓄電状況が示す蓄電量が所定の閾値未満の場合において、滞在時間の予想時間が所定時間よりも短い場合、充電種別を急速充電と特定する。また、充電種別特定部１２５は、蓄電状況が示す蓄電量が所定の閾値未満の場合において、滞在時間の予想時間が所定時間以上である場合、充電種別を普通充電と特定する。このようにすることで、管理装置１は、ユーザの施設における滞在予想時間に基づいて適切な充電種別を選択することができる。 For example, the charge type identification unit 125 identifies the charge type as quick charge when the estimated amount of stay time is shorter than the predetermined time when the amount of electricity indicated by the electricity storage state is less than a predetermined threshold. In addition, the charge type identifying unit 125 identifies the charge type as normal charge when the estimated amount of stay time is equal to or longer than a predetermined time when the amount of stored electricity indicated by the storage state is less than a predetermined threshold value. By doing so, the management device 1 can select an appropriate charging type based on the expected staying time at the user's facility.
　また、例えば、レストラン等の予めユーザの滞在時間の予想時間が予測しやすい施設では、当該施設の混雑状況に基づいて、滞在時間の予想時間を予測することも可能である。そこで、充電種別特定部１２５は、充電スタンド３が設置されている施設における状況に基づいて、当該施設におけるユーザの予想時間を推定してもよい。具体的には、充電種別特定部１２５は、充電スタンド３が設置されている施設から、当該施設における混雑状況を示す情報を取得し、当該情報に基づいて、当該施設におけるユーザの予想時間を推定する。そして、充電種別特定部１２５は、当該予想時間に基づいて当該充電スタンド３において電気機器に充電する電力量を取得する場合の充電種別を特定する。このようにすることで、管理装置１は、ユーザから滞在予想時間を受け付ける場合と同様に、適切な充電種別を選択することができる。 Further, for example, in a facility such as a restaurant where it is easy to predict the expected stay time of the user in advance, it is possible to predict the expected stay time based on the congestion status of the facility. Therefore, the charging type identifying unit 125 may estimate the estimated time of the user in the facility based on the situation in the facility where the charging stand 3 is installed. Specifically, the charging type identifying unit 125 acquires information indicating the congestion status of the facility from the facility in which the charging stand 3 is installed, and estimates the estimated time of the user at the facility based on the information. To do. Then, the charging type identifying unit 125 identifies the charging type when acquiring the amount of power to charge the electric device in the charging stand 3 based on the estimated time. By doing so, the management device 1 can select an appropriate charging type as in the case of receiving the expected stay time from the user.
　指示部１２６は、充電種別特定部１２５が特定した充電種別に基づく充電を充電スタンド３の充電設備３１に指示する。具体的には、指示部１２６は、充電種別特定部１２５が充電種別を特定したことに応じて、充電種別を含む指示情報を充電設備３１に送信することにより、当該充電種別に基づく充電を充電設備３１に指示する。充電設備３１は、指示情報に基づいて電気自動車Ｃに充電を行う。 The instruction unit 126 instructs the charging facility 31 of the charging stand 3 to perform charging based on the charging type specified by the charging type specifying unit 125. Specifically, the instruction unit 126 charges the charging based on the charge type by transmitting instruction information including the charge type to the charging facility 31 in response to the charge type specifying unit 125 specifying the charge type. Instruct the equipment 31. The charging facility 31 charges the electric vehicle C based on the instruction information.
