Description

売電情報通知装置、売電情報通知方法および充電システムPower sale information notification device, power sale information notification method, and charging system
　本開示は、充電システムにおける売電情報をユーザーに通知する売電情報通知装置、売電情報通知方法、および充電システムに関する。 This disclosure relates to a power sale information notification device, a power sale information notification method, and a charging system that notify a user of power sale information in the charging system.
　電気自動車等の車両を動作させるための電力を供給する車両電池は、車両の外部に設置された充電システムから充電される。充電システムにおいては、時間帯や場所によって車両の数が増減するため、充電を必要とする車両で混雑する場合、車両電池を迅速に充電できない可能性がある。 A vehicle battery that supplies electric power for operating a vehicle such as an electric vehicle is charged from a charging system installed outside the vehicle. In the charging system, the number of vehicles increases and decreases depending on the time zone and place. Therefore, when the vehicle is congested with vehicles that require charging, the vehicle battery may not be charged quickly.
　そこで、例えば、特許文献１には、節電すべき時間帯とされる節電時間帯を避けて充電計画を立てる技術が開示されている。これにより、電力の負荷の平準化やピークシフトに寄与することが可能となる。 Therefore, for example, Patent Document 1 discloses a technique for making a charging plan while avoiding a power saving time zone, which is a time zone for power saving. Thereby, it becomes possible to contribute to leveling of the load of electric power and peak shift.
　また、特許文献２には、充電システムの混雑度合いを推定して車両に混雑していない充電システムの情報を提供する技術が開示されている。 Further, Patent Document 2 discloses a technique for providing information on a charging system that is not congested in a vehicle by estimating the degree of congestion of the charging system.

　ところで、今後、充電システムにおいて、太陽光発電等のような再生可能エネルギーの利用が進むことが想定され、それに伴って、地域内で電力を生産、消費する地産地消化が進むことが想定される。 By the way, in the future, it is assumed that the use of renewable energy such as solar power generation will progress in the charging system, and along with that, it is assumed that local production and consumption of electric power will be produced and consumed in the region. .
　しかしながら、例えば、夕方における太陽光等の再生可能エネルギーによる発電が止まる頃、車両電池の充電動作が集中したような場合、電力需要が急激に変化する現象（いわゆるダックカーブ現象）が発生すると考えられる。このような現象が発生することで、地域内における充電システムにおいて電力不足が発生した場合、ブラックアウトが発生して車両の電力供給ができなくなるおそれがある。 However, for example, when the power generation by renewable energy such as sunlight stops in the evening, when the charging operation of the vehicle battery is concentrated, a phenomenon in which the power demand changes rapidly (so-called duck curve phenomenon) is considered to occur. . When such a phenomenon occurs, when power shortage occurs in a charging system in a region, there is a possibility that blackout occurs and the vehicle cannot be supplied with power.
　本開示は、充電システムにおける電力不足の発生を低減することが可能な売電情報通知装置、売電情報通知方法および充電システムを提供する。 The present disclosure provides a power sale information notification device, a power sale information notification method, and a charging system that can reduce the occurrence of power shortage in a charging system.
　本開示の一態様に係る売電情報通知装置は、売電情報取得部と、通知出力部と、車両側制御部とを有する。売電情報取得部は、現在地から車両の目的地に至るまでの間における走行路の周辺に位置する充電システムから、売電を要求する売電情報を取得する。車両側制御部は、車両に搭載された車両電池の充電量と、現在地から目的地に至るまでの電力量との差分電力を算出する。そして、車両側制御部は、この差分電力に基づいて、充電システムに売電可能であるか否かについて判定する。さらに、車両側制御部は、充電システムに売電可能であると判定した場合、充電システムにおける売電情報に係る通知を表示媒体に出力するように通知出力部を制御する。 The power sale information notification device according to an aspect of the present disclosure includes a power sale information acquisition unit, a notification output unit, and a vehicle-side control unit. The power sale information acquisition unit acquires power sale information for requesting power sale from a charging system located around the travel path from the current location to the destination of the vehicle. The vehicle-side control unit calculates a difference power between the amount of charge of the vehicle battery mounted on the vehicle and the amount of power from the current location to the destination. And a vehicle side control part determines whether it can sell power to a charging system based on this difference electric power. Further, when it is determined that power can be sold to the charging system, the vehicle-side control unit controls the notification output unit so as to output a notification related to the power selling information in the charging system to the display medium.
　本開示の他の態様は売電情報通知方法である。この売電情報通知方法によれば、車両に電力を供給する充電システムにおける売電を要求する売電情報をユーザーに通知する。この売電情報通知方法では、まず、現在地から車両の目的地に至るまでの間における走行路の周辺に位置する充電システムから、売電を要求する売電情報を取得する。一方、車両に搭載された車両電池の充電量と、現在地から目的地に至るまでの電力量との差分電力を算出する。そして、この差分電力に基づいて、充電システムに売電可能であるか否かについて判定する。充電システムに売電可能であると判定した場合、充電システムにおける売電情報に係る通知を表示媒体に出力する。 Another aspect of the present disclosure is a power sale information notification method. According to this power sale information notification method, the user is notified of power sale information for requesting power sale in a charging system that supplies power to the vehicle. In this power sale information notification method, first, power sale information for requesting power sale is acquired from a charging system located in the vicinity of the travel path from the current location to the destination of the vehicle. On the other hand, the power difference between the amount of charge of the vehicle battery mounted on the vehicle and the amount of power from the current location to the destination is calculated. Then, based on the difference power, it is determined whether or not power can be sold to the charging system.

The vehicle battery 11 is charged from a charging system such as the charging station 2 installed outside.
　また、車両１は、車両電池１１の残電力を用いて充電ステーション２等における充電装置２１を充電できるように構成される。車両１は、充電ステーション２における売電情報を取得することで、この売電情報を出力した充電ステーション２の情報をユーザーに通知する機能を有する売電情報通知装置１００を有する。 Further, the vehicle 1 is configured to be able to charge the charging device 21 in the charging station 2 or the like using the remaining power of the vehicle battery 11. The vehicle 1 has a power sale information notification device 100 having a function of notifying the user of information on the charging station 2 that has output the power sale information by acquiring the power sale information at the charging station 2.
　売電情報とは、電力が不足するおそれがある充電ステーション２が、車両１のユーザーに車両電池１１の残電力を売電する旨を要求する情報のことである。 The power sale information is information for requesting the user of the vehicle 1 to sell the remaining power of the vehicle battery 11 to the user of the vehicle 1 from the charging station 2 where there is a risk of power shortage.
　売電情報通知装置１００は、車両側通信部１１０と、電池情報取得部１２０と、車両側制御部１３０と、通知出力部１４０とを有する。 The power sale information notification device 100 includes a vehicle-side communication unit 110, a battery information acquisition unit 120, a vehicle-side control unit 130, and a notification output unit 140.
　車両側通信部１１０は、車両１および充電ステーション２に関する情報を管理する管理センター３と通信可能に構成され、管理センター３を介して充電ステーション２が出力する売電情報を取得する。具体的には、車両側通信部１１０は、現在地から車両１の目的地に至るまでの間における走行路の周辺に位置する充電ステーション２の売電情報を取得する。車両側通信部１１０は、本開示の「売電情報取得部」に対応する。 The vehicle-side communication unit 110 is configured to be communicable with a management center 3 that manages information related to the vehicle 1 and the charging station 2, and acquires power sale information output by the charging station 2 via the management center 3. Specifically, the vehicle-side communication unit 110 acquires power sale information of the charging station 2 that is located around the travel path from the current location to the destination of the vehicle 1. The vehicle-side communication unit 110 corresponds to the “power sale information acquisition unit” of the present disclosure.
　また、車両側通信部１１０は、売電情報の他に、現在地から充電ステーション２を介して目的地に至るまでの距離情報を管理センター３から取得し、売電情報および距離情報を車両側制御部１３０に出力する。 In addition to the power sale information, the vehicle-side communication unit 110 acquires distance information from the current location to the destination via the charging station 2 from the management center 3, and controls the power sale information and the distance information on the vehicle side. To the unit 130.
　電池情報取得部１２０は、車両電池１１の充電量の情報を取得して、車両側制御部１３０に出力する。 Battery information acquisition unit 120 acquires information on the amount of charge of vehicle battery 11 and outputs the information to vehicle-side control unit 130.
　車両側制御部１３０は、車両側通信部１１０から取得した距離情報と、電池情報取得部１２０から取得した車両電池１１の充電量とから、現在地から充電ステーション２を介して目的地に至るまでの使用電力量を算出する。なお、この電力量は、管理センター３で算出されていてもよい。 The vehicle-side control unit 130 obtains the distance information acquired from the vehicle-side communication unit 110 and the charge amount of the vehicle battery 11 acquired from the battery information acquisition unit 120 from the current location to the destination via the charging station 2. Calculate power consumption. The amount of power may be calculated by the management center 3.
　車両側制御部１３０は、車両電池１１の充電量と、算出した使用電力量との差分電力を算出し、この差分電力に応じて、売電情報を出力した充電ステーション２に売電可能であるか否かについて決定する。 The vehicle-side control unit 130 calculates the difference power between the charge amount of the vehicle battery 11 and the calculated power consumption amount, and can sell power to the charging station 2 that has output the power sale information according to the difference power. Decide whether or not.
　具体的には、車両側制御部１３０は、差分電力と所定電力とを比較して差分電力が所定電力以上である場合、売電情報を出力した充電ステーション２に売電可能であると決定する。 Specifically, the vehicle-side control unit 130 compares the differential power with the predetermined power and determines that the power can be sold to the charging station 2 that has output the power sale information when the differential power is equal to or greater than the predetermined power. .
　所定電力は、例えば、差分電力から車両電池１１から充電ステーション２に供給する電力を差し引いても、車両１が、所定の距離を走行可能な電力である。 The predetermined power is, for example, power that allows the vehicle 1 to travel a predetermined distance even if the power supplied from the vehicle battery 11 to the charging station 2 is subtracted from the differential power.
　車両側制御部１３０は、充電ステーション２に売電可能であると決定した場合、充電ステーション２における売電情報に係る通知を表示するための命令を通知出力部１４０に出力する。 If the vehicle-side control unit 130 determines that the power can be sold to the charging station 2, the vehicle-side control unit 130 outputs a command for displaying a notification related to the power sale information in the charging station 2 to the notification output unit 140.
　通知出力部１４０は、車両側制御部１３０から、上記命令を取得した場合、表示部１２に売電情報を出力した充電ステーション２を表示させる。 When the notification output unit 140 acquires the above command from the vehicle-side control unit 130, the notification output unit 140 causes the display unit 12 to display the charging station 2 that has output the power sale information.
　表示部１２は、例えば、車両１に搭載されたナビ等の車載装置である。なお、表示部１２は、例えば、スマートフォン等、車載装置以外の表示媒体であってもよい。 The display unit 12 is an in-vehicle device such as a navigation mounted on the vehicle 1, for example. The display unit 12 may be a display medium other than the in-vehicle device such as a smartphone.

　これにより、電力不足が発生するおそれがある充電ステーション２に予め電力供給することをユーザーに促すことができ、ひいては充電ステーション２における電力不足の発生を低減することができる。 This makes it possible to prompt the user to supply power in advance to the charging station 2 where there is a risk of power shortage, and as a result, the occurrence of power shortage at the charging station 2 can be reduced.
　また、車両側制御部１３０は、複数の充電ステーション２から売電情報を取得した場合、所定の情報を売電情報に付加した通知を通知出力部１４０に出力するようにしてもよい。 Further, when the vehicle-side control unit 130 acquires power sale information from the plurality of charging stations 2, the vehicle-side control unit 130 may output a notification in which predetermined information is added to the power sale information to the notification output unit 140.
　所定の情報は、例えば、待ち車両の少ない充電ステーション２から順に順位付けした情報、現在地に近い位置に位置する充電ステーション２から順に順位付けした情報、何らかの特典を付帯する売電インセンティブの付与率が高い充電ステーション２から順に順位付けした情報、および、供給電力の少ない充電ステーション２から順に順位付けした情報の何れか１つの情報である。 The predetermined information includes, for example, information ranked in order from the charging station 2 with few waiting vehicles, information ranked in order from the charging station 2 located at a position close to the current location, and a power sale incentive grant rate with some privilege. The information is any one of the information ranked in order from the highest charging station 2 and the information ranked in order from the charging station 2 with the smaller supply power.
　図２では、現在地に近い位置に位置する充電ステーション２を優先して順位付けした例を示している。例えば、図３に示す例では、売電インセンティブの付与率が高い充電ステーション２を優先して順位付けした例を示している。 FIG. 2 shows an example in which the charging stations 2 located near the current location are prioritized. For example, in the example illustrated in FIG. 3, an example in which the charging stations 2 having a high power selling incentive grant rate are prioritized is shown.
　図３では、売電インセンティブの高い順である、第２位置の充電ステーション２（１０％）、第１位置の充電ステーション２（８％）、第３位置の充電ステーション２（６％）の順で順位付けされている。なお、第１位置、第２位置及び第３位置とは、同一の地域内に設置された充電ステーション２の位置のことである。 In FIG. 3, the charging station 2 (10%) at the second position, the charging station 2 (8%) at the first position, and the charging station 2 (6%) at the third position in descending order of the power selling incentive. It is ranked by. The first position, the second position, and the third position are the positions of the charging station 2 installed in the same area.
　このようにすることで、ユーザーが表示部１２に表示された情報を見ることにより、ユーザーが行きたい充電ステーション２を選択することができる。 In this way, the user can select the charging station 2 that the user wants to go to by viewing the information displayed on the display unit 12.
　また、車両側制御部１３０は、上述の各条件のうち、何れか１つの条件を、ユーザーが選択した情報を表示するような通知を通知出力部１４０に出力するようにしてもよい。これにより、ユーザーの嗜好に応じた売電を効果的に行うことができる。 Further, the vehicle-side control unit 130 may output a notification that displays information selected by the user to any one of the above-described conditions to the notification output unit 140. Thereby, the power sale according to a user preference can be performed effectively.
　図１に戻って説明を続ける。充電ステーション２は、例えば、同一地域内の各位置に設置されており、充電装置２１に充電された電力を車両１に供給する。充電ステーション２は、充電側通信部２２と、充電側制御部２３とを有する。充電装置２１は、充電側制御部２３に制御されて車両１との間で電力を授受する。なお、図１では、充電ステーション２は２つのみ図示されている。 Referring back to FIG. The charging station 2 is installed at each position in the same area, for example, and supplies the vehicle 1 with the power charged in the charging device 21. The charging station 2 includes a charging side communication unit 22 and a charging side control unit 23. The charging device 21 is controlled by the charging side control unit 23 to exchange electric power with the vehicle 1. In FIG. 1, only two charging stations 2 are shown.
　充電側通信部２２は、管理センター３と通信可能に構成される。 The charging side communication unit 22 is configured to be able to communicate with the management center 3.
　充電側制御部２３は、所定の時間帯において供給される必要電力量を算出する。所定の時間帯は、例えば、現在の時間から、数時間程度後の時間帯のことである。 The charging-side control unit 23 calculates the required power amount that is supplied in a predetermined time zone. The predetermined time zone is, for example, a time zone that is several hours after the current time.
　必要電力量は、例えば、充電ステーション２における充電予約の情報、充電ステーション２周辺の車両１の充電状態の情報、及び、充電ステーション２における過去の履歴の情報の少なくとも１つ以上の情報に基づいて算出される電力量である。 The required power amount is based on, for example, at least one of information on charging reservation in the charging station 2, information on the charging state of the vehicle 1 around the charging station 2, and information on past history in the charging station 2. This is the amount of power calculated.
　充電予約の情報は、例えば車両１のユーザーが充電ステーション２を予約した際に設定する充電電力量の情報であり、例えば、管理センター３を介して充電側通信部２２により取得される。 The charging reservation information is, for example, information on the amount of charging power that is set when the user of the vehicle 1 reserves the charging station 2, and is acquired by the charging-side communication unit 22 via the management center 3, for example.
　充電側制御部２３は、充電予約の情報に基づいて、充電予約を受けている時間帯（所定の時間帯）において供給される第１電力量を算出する。 The charge-side control unit 23 calculates the first electric energy supplied in the time slot (predetermined time slot) in which the charge reservation is received based on the charge reservation information.
　充電状態の情報は、例えば充電ステーション２周辺を走行している車両１における車両電池１１の充電量の情報であり、例えば、管理センター３を介して充電側通信部２２により取得される。 The information on the charging state is information on the amount of charge of the vehicle battery 11 in the vehicle 1 traveling around the charging station 2, for example, and is acquired by the charging side communication unit 22 via the management center 3, for example.
　充電側制御部２３は、充電状態の情報に基づいて、今後、充電ステーション２において供給される第２電力量を推定する。 The charging-side control unit 23 estimates the second power amount that will be supplied in the future from the charging station 2 based on the charging state information.
　過去の履歴の情報は、例えば、所定の時間帯における充電ステーション２により車両１に供給された電力量の情報である。この情報は、例えば、充電ステーション２において記憶されている。 The past history information is, for example, information on the amount of power supplied to the vehicle 1 by the charging station 2 in a predetermined time zone. This information is stored in the charging station 2, for example.
　充電側制御部２３は、過去の履歴の情報に基づいて、所定の時間帯において供給される第３電力量を推定する。 The charging-side control unit 23 estimates the third power amount supplied in a predetermined time zone based on the past history information.
　充電側制御部２３は、第１電力量、第２電力量および第３電力量を用いて、必要電力量を算出する。例えば、充電側制御部２３は、第１電力量および第２電力量の和を、必要電力量として算出する。なお、必要電力量は、これに限定されず、第１電力量、第２電力量および第３電力量の何れか１つの電力量であってもよい。 The charge-side control unit 23 calculates the required power amount using the first power amount, the second power amount, and the third power amount. For example, the charging side control unit 23 calculates the sum of the first electric energy and the second electric energy as the required electric energy. The required power amount is not limited to this, and may be any one of the first power amount, the second power amount, and the third power amount.
　充電側制御部２３は、充電装置２１より現在、充電ステーション２により供給される供給電力量を取得し、この供給電力量と、必要電力量とを比較する。そして、充電側制御部２３は、必要電力量が供給電力量より大きい場合、充電ステーション２に電力を供給する必要があると判定する。 The charging-side control unit 23 acquires the amount of power supplied from the charging device 21 currently supplied by the charging station 2, and compares this amount of supplied power with the amount of required power. And the charge side control part 23 determines with it being necessary to supply electric power to the charging station 2, when required electric energy is larger than supply electric energy.
　充電側制御部２３が充電ステーション２に電力を供給する必要があると判定した場合、充電側通信部２２は、売電情報を管理センター３に出力する。すなわち、充電側制御部２３は、算出した必要電力量と、充電ステーション２において供給される供給電力量とに基づいて、売電を要求する売電情報を車両１に向けて出力するか否かについて判定する。 When the charging-side control unit 23 determines that it is necessary to supply power to the charging station 2, the charging-side communication unit 22 outputs power sale information to the management center 3. That is, the charging-side control unit 23 determines whether or not to output power sale information for requesting power sale to the vehicle 1 based on the calculated required power amount and the supplied power amount supplied at the charging station 2. Judge about.
　管理センター３は、車両１および充電ステーション２から情報を収集して管理する。管理センター３は、管理側通信部３１と、管理側記憶部３２と、管理側制御部３３とを有する。 Management center 3 collects and manages information from vehicle 1 and charging station 2. The management center 3 includes a management side communication unit 31, a management side storage unit 32, and a management side control unit 33.
　管理側通信部３１は、充電側通信部２２から売電情報を取得して、管理側記憶部３２に出力するとともに、車両側通信部１１０から充電予約情報および充電状態情報を取得して、管理側記憶部３２に出力する。 The management-side communication unit 31 acquires power sale information from the charging-side communication unit 22 and outputs it to the management-side storage unit 32, and also acquires charge reservation information and charge state information from the vehicle-side communication unit 110 for management. The data is output to the side storage unit 32.
　管理側制御部３３は、管理側記憶部３２に記憶された充電予約情報および充電状態情報に基づいて、これらの充電予約情報および充電状態情報を送信する必要がある充電ステーション２を地域内において選択する。管理側制御部３３は、選択した充電ステーション２に充電予約情報および充電状態情報を送信するように管理側通信部３１を制御する。 Based on the charging reservation information and the charging state information stored in the management side storage unit 32, the management side control unit 33 selects the charging station 2 that needs to transmit the charging reservation information and the charging state information in the area. To do. The management-side control unit 33 controls the management-side communication unit 31 to transmit the charging reservation information and the charging state information to the selected charging station 2.
　また、管理側制御部３３は、管理側記憶部３２に記憶された売電情報に基づいて、地域内を走行する車両１にこの売電情報を出力するように管理側通信部３１を制御する。 Further, the management-side control unit 33 controls the management-side communication unit 31 so as to output this power sale information to the vehicle 1 traveling in the area based on the power sale information stored in the management side storage unit 32. .
　このように、充電ステーション２が管理センター３を介して車両１に向けて売電情報を出力するので、ユーザーに充電ステーション２に売電するように誘導することができる。 Thus, since the charging station 2 outputs the power sale information to the vehicle 1 via the management center 3, it is possible to guide the user to sell the power to the charging station 2.
　なお、管理センター３は、車両専用の管理センターと、充電ステーション専用の管理センターとが別途設けられていてもよい。 In addition, the management center 3 may be provided with a management center dedicated to the vehicle and a management center dedicated to the charging station.
　以上のように構成された売電情報通知装置１００における売電情報通知制御の動作の一例について説明する。図４は、売電情報通知装置１００における売電情報通知制御の動作例の一例を示すフローチャートである。図４における処理は、車両１の走行中に適宜実行される。 An example of the operation of the power sale information notification control in the power sale information notification apparatus 100 configured as described above will be described. FIG. 4 is a flowchart illustrating an example of an operation example of power sale information notification control in the power sale information notification apparatus 100. The process in FIG. 4 is appropriately executed while the vehicle 1 is traveling.

Next, the vehicle-side control unit 130 calculates the amount of power used from the current location to the destination (step S102).
　次に、車両側制御部１３０は、電池情報取得部１２０より車両電池１１の充電量を取得して、車両電池１１の充電量と、使用電力量との差分電力を算出する（ステップＳ１０３）。 Next, the vehicle-side control unit 130 acquires the amount of charge of the vehicle battery 11 from the battery information acquisition unit 120, and calculates the difference power between the amount of charge of the vehicle battery 11 and the amount of power used (step S103).
　次に、車両側制御部１３０は、差分電力が所定電力以上であるか否かについて判定する（ステップＳ１０４）。判定の結果、差分電力が所定電力未満である場合（ステップＳ１０４、ＮＯ）、本制御は終了する。 Next, the vehicle-side control unit 130 determines whether or not the differential power is greater than or equal to a predetermined power (step S104). As a result of the determination, when the differential power is less than the predetermined power (step S104, NO), this control ends.
　一方、差分電力が所定電力以上である場合（ステップＳ１０４、ＹＥＳ）、車両側制御部１３０は、売電情報の通知指令を通知出力部１４０に出力する（ステップＳ１０５）。これにより、売電情報が表示部１２に表示されることで、この売電情報がユーザーに通知される。 On the other hand, when the differential power is equal to or greater than the predetermined power (step S104, YES), the vehicle-side control unit 130 outputs a power sale information notification command to the notification output unit 140 (step S105). As a result, the power sale information is displayed on the display unit 12 so that the user is notified of the power sale information.

FIG. 5 is a flowchart showing an example of an operation example of power sale information output control in the charging station 2. The process in FIG. 5 is appropriately executed while the charging station 2 is in operation.
　図５に示すように、充電側制御部２３は、充電側通信部２２により取得された充電予約情報および充電状態情報を取得する（ステップＳ２０１）。次に、充電側制御部２３は、所定の時間帯における必要電力量を算出する（ステップＳ２０２）。 As shown in FIG. 5, the charging side control unit 23 acquires the charging reservation information and the charging state information acquired by the charging side communication unit 22 (step S201). Next, the charging-side control unit 23 calculates a required power amount in a predetermined time zone (step S202).
　次に、充電側制御部２３は、充電装置２１から取得した供給電力量が必要電力量よりも小さいか否かについて判定する（ステップＳ２０３）。判定の結果、供給電力量が必要電力量以上である場合（ステップＳ２０３、ＮＯ）、本制御は終了する。一方、供給電力量が必要電力量よりも小さい場合（ステップＳ２０３、ＹＥＳ）、充電側制御部２３は、売電情報を出力する（ステップＳ２０４）。その後、本制御は終了する。 Next, the charging side control unit 23 determines whether or not the supplied power amount acquired from the charging device 21 is smaller than the required power amount (step S203). As a result of the determination, when the amount of supplied power is greater than or equal to the required amount of power (step S203, NO), this control ends. On the other hand, when the supplied power amount is smaller than the required power amount (step S203, YES), the charging-side control unit 23 outputs power sale information (step S204). Thereafter, this control ends.
