機器コントローラ及び充放電システムEquipment controller and charge / discharge system
　本開示は、蓄電池を充電するための機器コントローラ及び充放電システムに関する。 The present disclosure relates to an equipment controller and a charging / discharging system for charging a storage battery.
　近年、台風又は豪雨といった自然災害による長期の停電に備えて、停電時でも住宅内の負荷に電気を供給することができる蓄電池及び電気自動車充放電器が設置される住宅が増えている。また、インターネットを通じて停電を予想する情報を取得して定置型の蓄電池の充電を制御する技術も提案されている（例えば、特許文献１参照）。 In recent years, in preparation for a long-term power outage due to a natural disaster such as a typhoon or heavy rain, an increasing number of homes are equipped with storage batteries and electric vehicle chargers / dischargers that can supply electricity to the load inside the home even during a power outage. In addition, a technique for controlling the charging of a stationary storage battery by acquiring information for predicting a power outage via the Internet has also been proposed (see, for example, Patent Document 1).
特開２０１６－１５８４６号公報Japanese Unexamined Patent Publication No. 2016-15846
　特許文献１は、インターネットを通じて停電を予想する情報を取得して定置型の蓄電池を制御する技術を開示しているが、電動車両に搭載されている蓄電池を充電する技術を開示していない。電動車両に搭載されている蓄電池を充電する場合、電動車両充放電器と電動車両とが蓄電池を充電するための充放電ケーブルで接続されなければならないが、電動車両は、移動可能な物であるので、電動車両充放電器と電動車両とは充放電ケーブルで常に接続されているわけではない。そのため、停電が発生することを予想する情報を取得することができても、電動車両に搭載されている蓄電池を停電の発生に備えて充電することができない場合がある。電動車両充放電器と充放電ケーブルで常に接続されているわけではない電動車両に搭載されている蓄電池を停電の発生に備えて充電するための技術が要求されている。 Patent Document 1 discloses a technique for controlling a stationary storage battery by acquiring information for predicting a power failure through the Internet, but does not disclose a technique for charging a storage battery mounted on an electric vehicle. When charging the storage battery mounted on the electric vehicle, the electric vehicle charger / discharger and the electric vehicle must be connected by a charge / discharge cable for charging the storage battery, but the electric vehicle is a movable object. Therefore, the electric vehicle charger / discharger and the electric vehicle are not always connected by a charge / discharge cable. Therefore, even if information for predicting the occurrence of a power outage can be obtained, it may not be possible to charge the storage battery mounted on the electric vehicle in preparation for the occurrence of a power outage. There is a need for technology for charging a storage battery mounted on an electric vehicle, which is not always connected to the electric vehicle charger / discharger with a charge / discharge cable, in preparation for a power outage.
　本開示は、上記に鑑みてなされたものであって、電動車両充放電器と充放電ケーブルで常に接続されているわけではない電動車両に搭載されている蓄電池を停電の発生に備えて充電するための準備をユーザに促すとともに、住宅内の負荷に十分な電気を供給できる状態で待機する機器コントローラを得ることを目的とする。 The present disclosure has been made in view of the above, and charges a storage battery mounted on an electric vehicle, which is not always connected to the electric vehicle charger / discharger by a charge / discharge cable, in preparation for a power failure. The purpose is to urge the user to prepare for the operation and to obtain an equipment controller that stands by in a state where sufficient electricity can be supplied to the load in the house.
　上述した課題を解決し、目的を達成するために、本開示にかかる機器コントローラは、天候についての情報を有する天気予報サーバから天候に関連する情報を受信する第１通信部と、電動車両に搭載されている蓄電池を充電する機能を有する電動車両充放電器と通信を行う第２通信部と、停電が発生することを予想する情報が第１通信部によって受信され、かつ、電動車両充放電器と電動車両とが蓄電池を充電するための充放電ケーブルで接続されていないことを示す情報が第２通信部によって受信された場合、電動車両充放電器と電動車両とを充放電ケーブルで接続することを促す情報を出力する出力部とを有する。 In order to solve the above-mentioned problems and achieve the object, the device controller according to the present disclosure is mounted on the first communication unit that receives the information related to the weather from the weather forecast server having the information about the weather, and the electric vehicle. The second communication unit that communicates with the electric vehicle charger / discharger that has the function of charging the storage battery, and the first communication unit receives information that predicts that a power failure will occur, and the electric vehicle charge / discharger. When the second communication unit receives information indicating that the electric vehicle and the electric vehicle are not connected by the charge / discharge cable for charging the storage battery, the electric vehicle charge / discharger and the electric vehicle are connected by the charge / discharge cable. It has an output unit that outputs information prompting the user.
　本開示にかかる機器コントローラは、電動車両充放電器と充放電ケーブルで常に接続されているわけではない電動車両に搭載されている蓄電池を停電の発生に備えて充電するための準備をユーザに促し、充放電ケーブルに電動車両が接続されていればユーザの操作を必要とせず電動車両に搭載されている蓄電池に電力を充電し、住宅内の負荷に十分な電気を供給できる状態で待機することができるという効果を奏する。 The equipment controller according to the present disclosure urges the user to prepare for charging the storage battery mounted on the electric vehicle, which is not always connected to the electric vehicle charge / discharger by the charge / discharge cable, in case of a power failure. If the electric vehicle is connected to the charge / discharge cable, the storage battery mounted on the electric vehicle should be charged with electric power without the need for user operation, and the battery should stand by in a state where it can supply sufficient electricity to the load in the house. It has the effect of being able to.

　蓄電池５３に蓄積されている電力の残量があらかじめ決められた値を下回っていないと判断された場合（Ｓ８でＮｏ）、機器コントローラ３は、停電が発生することを予想する情報を解除する情報を天気予報サーバ５４から受信したか否かを判断する（Ｓ９）。例えば、機器コントローラ３の第２通信部３２が、停電が発生することを予想する情報を解除する情報が第１通信部３１によって受信されたか否かを判断する。 When it is determined that the remaining amount of electric power stored in the storage battery 53 is not less than a predetermined value (No in S8), the device controller 3 releases information for predicting that a power failure will occur. Is received from the weather forecast server 54 (S9). For example, the second communication unit 32 of the device controller 3 determines whether or not the information for canceling the information that predicts the occurrence of a power failure has been received by the first communication unit 31.
　機器コントローラ３が、停電が発生することを予想する情報を解除する情報を受信していない場合（Ｓ９でＮｏ）、充放電システム１はステップＳ７の動作を行う。すなわち、電動車両充放電器２は、蓄電池５３の充電を停止し、充放電ケーブル５６と電動車両５２との接続をロックし、電動車両５２と通信を行うことができる状態で待機する。 When the device controller 3 has not received the information for canceling the information for predicting the occurrence of a power failure (No in S9), the charge / discharge system 1 performs the operation in step S7. That is, the electric vehicle charge / discharger 2 stops charging the storage battery 53, locks the connection between the charge / discharge cable 56 and the electric vehicle 52, and stands by in a state where it can communicate with the electric vehicle 52.
　機器コントローラ３は、停電が発生することを予想する情報を解除する情報を受信した場合（Ｓ９でＹｅｓ）、停電が発生することを予想する情報を解除する情報を電動車両充放電器２に送信する。電動車両充放電器２は、ユーザの指示にしたがった動作を行う（Ｓ１０）。 When the device controller 3 receives the information for canceling the information for predicting the occurrence of a power failure (Yes in S9), the device controller 3 transmits the information for canceling the information for predicting the occurrence of a power failure to the electric vehicle charger / discharger 2. do. The electric vehicle charger / discharger 2 operates according to a user's instruction (S10).
　上述のように、機器コントローラ３は、停電が発生することを予想する情報を受信し、かつ、電動車両充放電器２と電動車両５２とが充放電ケーブル５６で接続されていないことを示す情報を受信した場合、電動車両充放電器２と電動車両５２とを充放電ケーブル５６で接続することを促す情報を出力する。したがって、機器コントローラ３は、電動車両充放電器２と充放電ケーブル５６で常に接続されているわけではない電動車両５２に搭載されている蓄電池５３を停電の発生に備えて充電するための準備をユーザに促すことができる。 As described above, the equipment controller 3 receives information that predicts that a power failure will occur, and information that indicates that the electric vehicle charger / discharger 2 and the electric vehicle 52 are not connected by the charge / discharge cable 56. Is received, information prompting the electric vehicle charge / discharger 2 and the electric vehicle 52 to be connected by the charge / discharge cable 56 is output. Therefore, the device controller 3 prepares to charge the storage battery 53 mounted on the electric vehicle 52, which is not always connected to the electric vehicle charge / discharger 2 by the charge / discharge cable 56, in preparation for the occurrence of a power failure. You can urge the user.
　機器コントローラ３は、停電が発生することを予想する情報を受信し、かつ、電動車両充放電器２と電動車両５２とが充放電ケーブル５６で接続されていると判断した場合、電動車両５２に搭載されている蓄電池５３を充電させる指示を電動車両充放電器２に送信する。電動車両充放電器２は、機器コントローラ３から送信された蓄電池５３を充電させる指示を受信し、当該指示にしたがって、系統電源５１から電動車両充放電器２に供給される交流電力をもとに蓄電池５３を充電する。これにより、充放電システム１は、停電の発生に備えて蓄電池５３を充電することができる。したがって、充放電システム１は、蓄電池５３に蓄積されている電力の残量が少ないことにより、電動車両５２が走行することができない状態を防止することができ、かつ、停電が発生した場合に負荷５８に電力が供給されない状態を回避することができる。 When the device controller 3 receives information that predicts that a power failure will occur and determines that the electric vehicle charger / discharger 2 and the electric vehicle 52 are connected by the charge / discharge cable 56, the device controller 3 connects to the electric vehicle 52. An instruction to charge the mounted storage battery 53 is transmitted to the electric vehicle charger / discharger 2. The electric vehicle charger / discharger 2 receives an instruction to charge the storage battery 53 transmitted from the device controller 3, and is based on the AC power supplied from the system power supply 51 to the electric vehicle charger / discharger 2 according to the instruction. The storage battery 53 is charged. As a result, the charging / discharging system 1 can charge the storage battery 53 in preparation for the occurrence of a power failure. Therefore, the charge / discharge system 1 can prevent the electric vehicle 52 from being unable to travel due to the low remaining amount of electric power stored in the storage battery 53, and is loaded when a power failure occurs. It is possible to avoid a state in which power is not supplied to 58.
　また、機器コントローラ３が受信した停電が発生することを予想する情報をもとに、蓄電池５３が充電することができる上限まで充電されたと判断された場合、電動車両充放電器２は、蓄電池５３の充電を停止し、充放電ケーブル５６と電動車両５２との接続をロックし、電動車両５２と通信を行うことができる状態で待機する。電動車両充放電器２と電動車両５２との通信が行われるので、充放電システム１は、停電が発生した後、系統電源５１より充放電システム１への電源の供給が無くなることで、即座に自立運転に移行できなくなる状態を回避することができ、停電が発生した後でもユーザによる受付部３４からの指示により蓄電池５３に蓄積されている電力をもとにした交流電力を負荷５８に供給することができる。すなわち、充放電システム１は、停電が発生した後でも機器コントローラ３の電源を供給し続ける事ができ、自立運転を行うことができる。 Further, when it is determined that the storage battery 53 has been charged to the upper limit that can be charged based on the information received by the device controller 3 that predicts that a power failure will occur, the electric vehicle charger / discharger 2 uses the storage battery 53. The charging of the battery is stopped, the connection between the charge / discharge cable 56 and the electric vehicle 52 is locked, and the battery stands by in a state where it can communicate with the electric vehicle 52. Since the electric vehicle charge / discharger 2 and the electric vehicle 52 communicate with each other, the charge / discharge system 1 immediately loses power supply to the charge / discharge system 1 from the system power supply 51 after a power failure occurs. It is possible to avoid a state in which it is not possible to shift to independent operation, and even after a power failure occurs, AC power based on the power stored in the storage battery 53 is supplied to the load 58 according to the instruction from the reception unit 34 by the user. be able to. That is, the charge / discharge system 1 can continue to supply power to the device controller 3 even after a power failure occurs, and can operate independently.
　また、電動車両充放電器２が電動車両５２と通信を行うことができる状態で待機する場合、電動車両充放電器２が電動車両５２と通信を行うことにより、蓄電池５３に蓄積されている電力は減少する。しかしながら、蓄電池５３に蓄積されている電力の残量があらかじめ決められた値を下回ったと判断された場合、機器コントローラ３は蓄電池５３を充電させる指示を電動車両充放電器２に送信し、電動車両充放電器２は、当該指示にしたがって、系統電源５１から電動車両充放電器２に供給される交流電力をもとに蓄電池５３を充電する。これにより、停電が発生する前に蓄電池５３に蓄積されている電力があらかじめ決められた値を下回ることを防止することができる。したがって、充放電システム１は、蓄電池５３に蓄積されている電力の残量が少ないことにより、電動車両５２が走行することができない状態を防止することができ、かつ、停電が発生した場合に負荷５８に電力が供給されない状態を回避することができる。 Further, when the electric vehicle charger / discharger 2 stands by in a state where it can communicate with the electric vehicle 52, the electric power stored in the storage battery 53 by the electric vehicle charger / discharger 2 communicating with the electric vehicle 52. Decreases. However, when it is determined that the remaining amount of electric power stored in the storage battery 53 is less than a predetermined value, the device controller 3 transmits an instruction to charge the storage battery 53 to the electric vehicle charger / discharger 2, and the electric vehicle The charging / discharging device 2 charges the storage battery 53 based on the AC power supplied from the system power supply 51 to the electric vehicle charging / discharging device 2 according to the instruction. As a result, it is possible to prevent the electric power stored in the storage battery 53 from falling below a predetermined value before the power failure occurs. Therefore, the charge / discharge system 1 can prevent the electric vehicle 52 from being unable to travel due to the low remaining amount of electric power stored in the storage battery 53, and is loaded when a power failure occurs. It is possible to avoid a state in which power is not supplied to 58.
