　ユーザによる電力システム１の利用例について説明する。ユーザは、移動体４０に搭載された蓄電装置１０を、例えばユーザの自宅または充電ステーション等に備えられた充電装置３０によって充電する。ユーザは、電力装置２０が設置された施設まで移動体４０で移動する。ユーザは、蓄電装置１０と電力装置２０とを接続して、蓄電装置１０による売電を開始する。売電が終了すると、売電電力量に応じた報酬がユーザに付与される。ユーザに付与される報酬の内容は、任意に定められてもよい。例えば、報酬は、金銭、仮想通貨、および所定サービスに利用可能なポイント等を含んでもよい。例えば、報酬は、電力装置２０が設置された施設におけるユーザの支払料金を減額する権利を含んでもよい。当該施設は、例えばレストランおよび電気量販店、ならびにそれらに関係する駐車場等の商業施設を含んでもよい。報酬の付与は、例えば報酬に相当するチケットを発券することによって実行されてもよい。報酬の付与は、報酬に相当する電子データをユーザの識別情報に対応付けて記憶することによって実行されてもよい。本実施形態において、報酬の付与は、電力装置２０によって実行される。他の実施形態において、報酬の付与は、例えばインターネット等の通信ネットワークを介して電力装置２０と通信可能な外部サーバが実行してもよい。例えば、ユーザがスマートフォンのアプリケーションで清算開始ボタンをクリックすると、外部サーバからの通信に応じて電力装置２０は受電動作を終了する。電力装置２０は、それまでに蓄電装置１０から売電された電力の報酬を算出して外部サーバに送信する。外部サーバは、その報酬に相当する減額のバーコードまたはＱＲコード（登録商標）等のコード画像を作成してユーザのスマートフォンに送信する。ユーザは、例えば食事または商品購入の清算時に、スマートフォン上に表示させたコード画像を提示することで支払いの減額を受けることができる。 The usage example of the power system 1 by a user is demonstrated. The user charges the power storage device 10 mounted on the mobile unit 40, for example, by the charging device 30 provided at the user's home or at a charging station. The user moves with the mobile body 40 to the facility where the power device 20 is installed. The user connects the storage device 10 and the power device 20, and starts selling electricity by the storage device 10. When the sale of electricity ends, a reward according to the amount of sale of electricity is given to the user. The content of the reward given to the user may be arbitrarily determined. For example, the reward may include money, virtual currency, points available for a predetermined service, and the like. For example, the reward may include the right to reduce the user's payment fee at the facility where the power device 20 is installed. The facilities may include commercial facilities such as, for example, restaurants and electricity retailers, and the parking lots associated with them. The grant of the reward may be performed, for example, by issuing a ticket corresponding to the reward. The grant of the reward may be performed by storing electronic data corresponding to the reward in association with the identification information of the user. In the present embodiment, the provision of the reward is performed by the power device 20. In another embodiment, the reward may be provided by an external server that can communicate with the power device 20 via a communication network such as the Internet. For example, when the user clicks the settlement start button with the application of the smartphone, the power device 20 ends the power reception operation according to the communication from the external server. The power device 20 calculates the reward of the power sold by the power storage device 10 so far and transmits the calculated reward to the external server. The external server creates a code image such as a reduced barcode or QR code (registered trademark) corresponding to the reward and transmits it to the user's smartphone. The user can receive a reduction in payment by presenting a code image displayed on the smartphone, for example, at the time of clearing of a meal or a product purchase.
　このように、電力システム１を利用するユーザは、例えば蓄電装置１０に蓄積された電力を、電力装置２０が設置された任意の場所において売電可能である。したがって、ユーザが売電可能な機会が増加するので、電力を売電する技術の利便性が向上する。また、蓄電装置１０に蓄積される電力の利用が促進されるので、ユーザにとって当該電力の利用効率が向上する。また、ユーザに対して、電力装置２０が設置された場所に移動する動機付けを与えることができる。このため、例えば当該場所におけるユーザの経済活動が活性化する。 Thus, a user who uses power system 1 can sell, for example, the power stored in power storage device 10 at any place where power device 20 is installed.

　日時は、蓄電装置１０の充放電が実行されたタイムスタンプである。制御部１５は、例えば蓄電装置１０の充放電が終了すると、充放電の終了した日時を記憶部１４に記憶してもよい。 The date is a time stamp at which charge and discharge of power storage device 10 were performed. For example, when charge and discharge of power storage device 10 are completed, control unit 15 may store the date and time when charge and discharge are completed in storage unit 14.
　充放電電力量は、蓄電装置１０の充放電が実行されたときの充放電電力量である。図５において、充電電力量を正の数値で示し、放電電力量を負の数値で示す。制御部１５は、例えば蓄電装置１０の充放電が終了すると、センサ部１３を用いて検出した充放電電力量を記憶部１４に記憶してもよい。この際、放電効率および充電効率を考慮して、充放電電力量が算出されてもよい。以下の説明においては、具体的な充放電電力量の数値を用いて説明する場合、簡略化のため充電効率および放電効率は１．０であるものとして説明する。 The charge / discharge power amount is a charge / discharge power amount when charge / discharge of the power storage device 10 is performed. In FIG. 5, the charge energy is indicated by a positive value, and the discharge energy is indicated by a negative value. For example, when charge and discharge of power storage device 10 are completed, control unit 15 may store, in storage unit 14, the charge and discharge power amount detected using sensor unit 13. At this time, the charge / discharge power may be calculated in consideration of the discharge efficiency and the charge efficiency. In the following description, the charge efficiency and the discharge efficiency are assumed to be 1.0 for simplification, in the case of using specific numerical values of charge and discharge electric energy.
　属性は、蓄電装置１０に充電電力を供給した装置、または蓄電装置１０が放電電力を供給した装置を示す情報である。例えば、属性は、電力装置２０、第１充電装置３０ａ、第２充電装置３０ｂ、または移動体４０のいずれかを示してもよい。制御部１５は、例えば蓄電装置１０と電力装置２０とが接続されているときに蓄電装置１０の充放電が実行されると、属性を「電力装置」として記憶部１４に記憶してもよい。制御部１５は、例えば蓄電装置１０と充電装置３０とが接続されているときに蓄電装置１０の充電が実行されると、充電装置３０から取得する通知に基づいて、充電装置３０が第１充電装置３０ａおよび第２充電装置３０ｂのいずれであるかを特定してもよい。制御部１５は、充電装置３０の特定結果に応じて、属性を「第１充電装置」または「第２充電装置」として記憶部１４に記憶してもよい。制御部１５は、例えば蓄電装置１０が電力装置２０および充電装置３０のいずれとも接続されていないときに蓄電装置１０の充放電が実行されると、属性を「移動体」として記憶部１４に記憶してもよい。 The attribute is information indicating a device that has supplied the charging power to the power storage device 10 or a device that has the discharge power supplied by the power storage device 10. For example, the attribute may indicate any of the power device 20, the first charging device 30a, the second charging device 30b, or the mobile object 40. For example, when charge and discharge of power storage device 10 are performed when power storage device 10 and power device 20 are connected, control unit 15 may store the attribute as “power device” in storage unit 14. For example, when charging of power storage device 10 is executed when power storage device 10 and charging device 30 are connected, control unit 15 sets the first charging device 30 to charge the charging device 30 based on the notification acquired from charging device 30. It may be specified which of the device 30a and the second charging device 30b. The control unit 15 may store the attribute in the storage unit 14 as “first charging device” or “second charging device” according to the identification result of the charging device 30. For example, when charge / discharge of power storage device 10 is performed when power storage device 10 is not connected to either power device 20 or charging device 30, control unit 15 stores the attribute as “mobile” in storage unit 14. You may
　残存容量は、蓄電装置１０の充放電が終了したときの蓄電池１１の残存容量である。制御部１５は、センサ部１３を用いて検出した残存容量を記憶部１４に記憶してもよい。 The remaining capacity is the remaining capacity of storage battery 11 when charging / discharging of power storage device 10 is completed. The control unit 15 may store the remaining capacity detected using the sensor unit 13 in the storage unit 14.
　第１パラメータは、蓄電池１１の残存容量のうち、再生可能エネルギー由来の電力量に相当するパラメータである。制御部１５は、第１充電装置３０ａからの充電電力量に応じて第１パラメータを増加させてもよい。例えば、制御部１５は、第１充電装置３０ａからの充電電力量だけ第１パラメータを増加させてもよい。 The first parameter is a parameter corresponding to the amount of power derived from renewable energy among the remaining capacity of the storage battery 11. The control unit 15 may increase the first parameter in accordance with the amount of charge power from the first charging device 30a. For example, the control unit 15 may increase the first parameter by the charging power amount from the first charging device 30a.
　第２パラメータは、蓄電池１１の残存容量のうち、枯渇性エネルギー由来の電力量に相当するパラメータである。制御部１５は、第２充電装置３０ｂからの充電電力量に応じて第２パラメータを増加させてもよい。例えば、制御部１５は、第２充電装置３０ｂからの充電電力量だけ増加してもよい。 The second parameter is a parameter corresponding to the amount of power derived from the depletable energy out of the remaining capacity of the storage battery 11. The control unit 15 may increase the second parameter in accordance with the amount of charge power from the second charging device 30b. For example, the control unit 15 may increase the charging power amount from the second charging device 30b.
　上述したように、蓄電装置１０は、移動体４０の回生ブレーキによっても充電され得る。本実施形態において、制御部１５は、移動体４０の回生ブレーキによる充電電力量に応じて、第２パラメータを増加させる。例えば、制御部１５は、移動体４０の回生ブレーキによる充電出力量だけ第２パラメータを増加させてもよい。かかる構成は、次に説明する思想に基づく。すなわち、蓄電装置１０に再生可能エネルギー由来の電力のみが蓄積されている状況は比較的稀であり、再生可能エネルギー由来の電力および枯渇性エネルギー由来の電力の両方が蓄電装置１０に蓄積されている蓋然性が高い。したがって、移動体４０は、蓄電装置１０に蓄積された再生可能エネルギー由来の電力および枯渇性エネルギー由来の電力の両方を消費すると考えることができる。回生ブレーキは、移動体４０の走行によって消費された電力の一部を回収するものである。このため、回生ブレーキによる充電電力は、枯渇性エネルギー由来の電力の一部と考えることができる。本実施形態では、移動体４０の回生ブレーキによる充電電力量に応じて第２パラメータが増加する。かかる構成によれば、蓄電池１１の残存容量のうち再生可能エネルギー由来の電力量に相当する第１パラメータの精度が向上する。 As described above, the power storage device 10 can also be charged by the regenerative brake of the moving body 40. In the present embodiment, the control unit 15 increases the second parameter in accordance with the amount of charging power by the regenerative brake of the moving body 40. For example, the control unit 15 may increase the second parameter by the charge output amount by the regenerative brake of the moving body 40. Such configuration is based on the concept described below. That is, the situation where only power derived from renewable energy is stored in power storage device 10 is relatively rare, and both power derived from renewable energy and power derived from depletable energy are stored in power storage device 10 It is highly probable. Therefore, mobile unit 40 can be considered to consume both the electric power derived from the renewable energy and the electric power derived from the depletable energy stored in power storage device 10. The regenerative brake is for recovering a part of the power consumed by the traveling of the moving body 40. Therefore, the charging power by the regenerative brake can be considered as part of the power derived from the depletable energy. In the present embodiment, the second parameter increases in accordance with the amount of charging power by the regenerative brake of the moving body 40. According to this configuration, among the remaining capacity of the storage battery 11, the accuracy of the first parameter corresponding to the electric energy derived from the renewable energy is improved.
　他の実施形態において、制御部１５は、移動体４０の回生ブレーキによる充電電力量に応じて、第１パラメータを増加させてもよい。かかる構成は、次に説明する思想に基づく。すなわち、回生ブレーキは、上述したように移動体４０の走行のために消費された電力の一部を回収するものである。回生ブレーキによって回収される電力は、例えば電力の生成に二酸化炭素の排出を伴わない点で、枯渇性エネルギー由来の電力と相違する。このため、回生ブレーキによる充電電力は、枯渇性エネルギー由来の電力よりも、再生可能エネルギー由来の電力に近い性質を有すると考えることができる。他の実施形態では、移動体４０の回生ブレーキによる充電電力量に応じて第１パラメータが増加する。このため、蓄電池１１の残存容量のうち枯渇性エネルギー由来の電力量に相当する第２パラメータの精度が向上する。 In another embodiment, the control unit 15 may increase the first parameter in accordance with the amount of charging power by the regenerative brake of the moving body 40. Such configuration is based on the concept described below. That is, as described above, the regenerative brake is for recovering a part of the power consumed for traveling of the moving body 40. The power recovered by the regenerative brake is different from the power derived from depletable energy, for example, in that the generation of the power does not involve the emission of carbon dioxide. For this reason, it can be considered that the charging power by the regenerative brake has a property closer to the power derived from the renewable energy than the power derived from the depletable energy. In another embodiment, the first parameter increases in accordance with the amount of charging power by the regenerative brake of the moving body 40. Therefore, among the remaining capacity of storage battery 11, the accuracy of the second parameter corresponding to the amount of power derived from the depletable energy is improved.
　制御部１５は、蓄電装置１０から電力装置２０に対する売電電力量に応じて第１パラメータを減少させてもよい。例えば、制御部１５は、電力装置２０に対する売電電力量だけ第１パラメータを減少させてもよい。かかる構成は、蓄電装置１０から電力装置２０に対する売電において、再生可能エネルギー由来の電力が優先的に用いられることに相当する。 Control unit 15 may decrease the first parameter in accordance with the amount of power sold by power storage device 10 to power device 20. For example, the control unit 15 may decrease the first parameter by the amount of power sold to the power device 20. Such a configuration corresponds to the preferential use of the power derived from the renewable energy in the sale of power from the storage device 10 to the power device 20.
　制御部１５は、蓄電装置１０が電力装置２０に対する売電以外で放電すると、放電電力量に応じて第１パラメータおよび第２パラメータの合計値を減少させてもよい。第１パラメータおよび第２パラメータの合計値を減少させる際、制御部１５は、例えば第２パラメータがゼロよりも大きい場合、第１パラメータよりも第２パラメータを優先的に減少させてもよい。かかる構成は、蓄電装置１０から電力装置２０に対する売電以外の放電において、枯渇性エネルギー由来の電力が優先的に用いられることに相当する。 When power storage device 10 discharges other than selling power to power device 20, control unit 15 may decrease the total value of the first parameter and the second parameter according to the amount of discharged power. When reducing the total value of the first parameter and the second parameter, for example, when the second parameter is larger than zero, the control unit 15 may preferentially reduce the second parameter over the first parameter. Such a configuration corresponds to the preferential use of the power derived from the depletable energy in the discharge other than the sale of power from storage device 10 to power device 20.
