The user may feel dissatisfied due to the low amount of available power, or the power storage unit may be in an overcharged state due to the large amount of available power for charging when the remaining capacity of the power storage unit is relatively large. You can prevent this from happening.

In this way, the information necessary to run the operating program is created in advance on the server, so when the power storage unit operates using the operating program, information on the remaining capacity and current time is stored in the storage unit. There is no need for units to acquire it themselves. Therefore, since the functions of the power storage unit can be minimized, the cost of the power storage unit can be reduced.
　第５の発明では、蓄電ユニットが設置されている施設において停電が発生した場合、まず蓄電ユニットから施設に電力が供給され、しかる後、発電機が動作を開始すると、蓄電ユニットに代わり発電機から施設に電力が供給されるようになる。これにより、例えば、常時電力供給が必要な病院等の施設において停電が発生した際、該施設への電力供給を継続して行うことができる。 In the fifth invention, when a power outage occurs in a facility where a power storage unit is installed, power is first supplied from the power storage unit to the facility, and then, when the generator starts operating, the power is supplied from the generator instead of the power storage unit. Electricity is now supplied to the facility. Thereby, for example, when a power outage occurs in a facility such as a hospital that requires constant power supply, it is possible to continue supplying power to the facility.

In addition, by having the cloud server 3 take charge of each control process etc. of the power storage unit 11, it is possible to use AI technology etc. introduced to the cloud server 3 from time to time without updating the software or changing the hardware of the power storage unit 11. You can use the latest software, etc.
　次に、図４を用いて管理用端末４について説明する。 Next, the management terminal 4 will be explained using FIG. 4.
　管理用端末４は、蓄電ユニット１１の管理者が使用するコンピュータであって、端末側通信部２５と、操作入力部２６と、表示部２７と、端末制御部２８と、を備えている。 The management terminal 4 is a computer used by the administrator of the power storage unit 11, and includes a terminal side communication section 25, an operation input section 26, a display section 27, and a terminal control section 28.
　端末側通信部２５は、通信ネットワーク５を介してクラウドサーバ３と通信可能な通信装置であり、端末制御部２８とは情報を送受信可能に接続されている。 The terminal-side communication unit 25 is a communication device that can communicate with the cloud server 3 via the communication network 5, and is connected to the terminal control unit 28 so that information can be transmitted and received.
　操作入力部２６は、管理者が入力操作可能な入力装置であって、例えば、キーボードやマウスである。該操作入力部２６は、端末制御部２８と接続されており、管理者により入力された操作、例えば、蓄電ユニット１１の充放電の停止や再開の操作を端末制御部２８に送信するようになっている。 The operation input unit 26 is an input device that can be operated by the administrator, and is, for example, a keyboard or a mouse. The operation input section 26 is connected to the terminal control section 28 and is configured to transmit operations input by the administrator, such as operations for stopping and restarting charging and discharging of the power storage unit 11, to the terminal control section 28. ing.
　表示部２７は、端末制御部２８と接続されたディスプレイ装置であり、蓄電ユニット１１の状態情報等を表示可能になっている。 The display unit 27 is a display device connected to the terminal control unit 28 and is capable of displaying status information of the power storage unit 11 and the like.
　端末制御部２８は、図示しないプロセッサを備えており、通信ネットワーク５を介してクラウドサーバ３から送信される蓄電ユニット１１の状態情報や蓄電ユニット１１の制御情報を、端末側通信部２５を介して受信するようになっている。そして、該端末制御部２８は、受信した各情報が表示部２７に表示されるように該表示部２７に指令を行うように構成されている。 The terminal control unit 28 includes a processor (not shown), and transmits state information of the power storage unit 11 and control information of the power storage unit 11 transmitted from the cloud server 3 via the communication network 5 to the terminal side communication unit 25.

　また、端末制御部２８は、操作入力部２６に入力された操作を受信すると、該入力操作に対応する指令をクラウドサーバ３に送信するようになっている。例えば、蓄電ユニット１１の充放電を停止させる操作が操作入力部２６に入力された場合、端末制御部２８からクラウドサーバ３に蓄電ユニット１１の充放電停止が指令される。該指令を受信したクラウドサーバ３は、蓄電ユニット１１に充放電を停止させる制御情報を送信するようになるので、管理者は、管理用端末４からクラウドサーバ３を介して蓄電ユニット１１を遠隔制御することが可能となっている。 Furthermore, when the terminal control unit 28 receives an operation input to the operation input unit 26, it transmits a command corresponding to the input operation to the cloud server 3. For example, when an operation to stop charging and discharging the power storage unit 11 is input to the operation input unit 26, the terminal control unit 28 instructs the cloud server 3 to stop charging and discharging the power storage unit 11. After receiving the command, the cloud server 3 transmits control information to stop charging and discharging to the power storage unit 11. Therefore, the administrator remotely controls the power storage unit 11 from the management terminal 4 via the cloud server 3. It is now possible to do so.
　次に、図５を用いて第１の実施形態に係る管理システム１の動作について説明する。 Next, the operation of the management system 1 according to the first embodiment will be described using FIG. 5.
　ステップＳ１では、管理用端末４の端末制御部２８は、蓄電ユニット１１の管理者が操作入力部２６を用いて入力した蓄電ユニット１１の設定操作を受信したため、クラウドサーバ３のサーバ制御部２２に操作入力された蓄電ユニット１１の設定情報を送信する。本実施形態では、蓄電ユニット１１の設定情報には、蓄電ユニット１１が電気的に接続された施設２に発電機９が設置されているか否かの情報、施設２がどのような種類の施設であるかの情報（例えば、病院）、並びに、蓄電ユニット１１の位置、蓄電容量、定格出力、定格出力電圧、定格出力周波数、及び、定格出力可能時間等の情報が含まれている。 In step S1, the terminal control unit 28 of the management terminal 4 receives the setting operation for the power storage unit 11 input by the administrator of the power storage unit 11 using the operation input unit 26, so the terminal control unit 28 of the management terminal 4 The setting information of the power storage unit 11 inputted by the operation is transmitted. In this embodiment, the setting information of the power storage unit 11 includes information as to whether the generator 9 is installed in the facility 2 to which the power storage unit 11 is electrically connected, and what type of facility the facility 2 is.

　ステップＳ２では、蓄電ユニット１１の蓄電制御部１８は、サーバ制御部２２へ接続要求を送信する。 In step S2, the power storage control section 18 of the power storage unit 11 transmits a connection request to the server control section 22.
　ステップＳ３では、サーバ制御部２２は、蓄電制御部１８からの接続要求を受信すると、該蓄電制御部１８との接続処理を実行する。該サーバ制御部２２は、該接続処理が完了、つまり、サーバ制御部２２と蓄電制御部１８との間の通信回線が開通すると、蓄電ユニット１１の開通通知を端末制御部２８に送信する。 In step S3, upon receiving the connection request from the power storage control unit 18, the server control unit 22 executes connection processing with the power storage control unit 18. When the connection process is completed, that is, when the communication line between the server control section 22 and the power storage control section 18 is opened, the server control section 22 transmits an opening notification of the power storage unit 11 to the terminal control section 28.
　ステップＳ４では、蓄電制御部１８は、蓄電部センサ１３及び電力変換部センサ１５から蓄電部１２及び電力変換部１４（蓄電ユニット１１）の状態情報を取得する。 In step S4, the power storage control unit 18 acquires status information of the power storage unit 12 and the power conversion unit 14 (power storage unit 11) from the power storage unit sensor 13 and the power conversion unit sensor 15.
　ステップＳ５では、蓄電制御部１８は、取得した蓄電ユニット１１の状態情報をサーバ制御部２２に送信する。 In step S5, the power storage control unit 18 transmits the acquired status information of the power storage unit 11 to the server control unit 22.
　ステップＳ６では、サーバ制御部２２は、蓄電ユニット１１の状態情報を受信すると、該状態情報から該蓄電ユニット１１の制御情報を設定し、蓄電制御部１８に送信する。 In step S<b>6 , upon receiving the state information of the power storage unit 11 , the server control unit 22 sets control information for the power storage unit 11 from the state information and transmits it to the power storage control unit 18 .
　ステップＳ７では、サーバ制御部２２は、蓄電ユニット１１の状態情報や制御情報を管理用端末４に送信する。該管理用端末４では、端末制御部２８が受信した蓄電ユニット１１の状態情報や制御情報を表示部２７に表示させる。 In step S7, the server control unit 22 transmits the status information and control information of the power storage unit 11 to the management terminal 4. In the management terminal 4, the status information and control information of the power storage unit 11 received by the terminal control section 28 are displayed on the display section 27.
　ステップＳ８では、サーバ制御部２２は、受信した蓄電ユニット１１の状態情報から蓄電ユニット１１の蓄電部１２の残容量を算出する。本実施形態では、残容量は、蓄電ユニット１１の状態情報における電流値を積算することにより算出する。 In step S8, the server control unit 22 calculates the remaining capacity of the power storage section 12 of the power storage unit 11 from the received status information of the power storage unit 11. In this embodiment, the remaining capacity is calculated by integrating the current values in the state information of the power storage unit 11.
　ステップＳ９では、サーバ制御部２２の生成部２３は、動作プログラムを生成する。本実施形態では、動作プログラムには、縦軸に放電使用可能電力量、横軸に蓄電部１２の残容量をとる制御マップが含まれており、該制御マップが生成部２３により生成されるようになっている。具体的には、該生成部２３は、サーバ記憶部２４に随時記憶された蓄電ユニット１１の状態情報の履歴から図６に一例で示す蓄電ユニット１１の使用時間帯毎の放電使用電力量を演算し、該演算した使用時間帯毎の放電使用電力量に基づいて、図７に一例で示す蓄電部１２の使用時間帯及び蓄電部１２の残容量に応じて異なる放電使用可能電力量が設定された制御マップを生成する。ここで、図７に示す制御マップは、図６に示す、晩（午後５時～午後１１時）、昼間（午前１０時～午後５時）、朝（午前７時～午前１０時）、夜間（午後１１時～午前７時）の順に放電使用電力量が多い使用履歴に基づいて設定されている。これにより、蓄電ユニット１１のユーザーが比較的電気を使用する使用時間帯において放電使用可能電力量が少ないことに起因してユーザーに不満感を与えてしまうことを防ぐことができる。また、図７で示す例では、蓄電部１２の残容量が少ないほど、放電使用可能電力量が少なく設定されることにより、蓄電部１２の過放電による該蓄電部１２の劣化等を防ぐようになっている。 In step S9, the generation unit 23 of the server control unit 22 generates an operating program. In the present embodiment, the operation program includes a control map in which the vertical axis represents the amount of dischargeable power and the horizontal axis represents the remaining capacity of the power storage unit 12, and the control map is generated by the generating unit 23. It has become. Specifically, the generation unit 23 calculates the amount of discharged power used for each usage time period of the power storage unit 11, which is shown as an example in FIG. Then, based on the calculated discharging power usage amount for each use time period, different dischargeable usable power amounts are set depending on the use time period of the power storage unit 12 and the remaining capacity of the power storage unit 12, as shown in an example in FIG. 7. generate a control map. Here, the control map shown in FIG. 7 is based on the control map shown in FIG. (from 11:00 p.m. to 7:00 a.m.) is set based on the usage history in which the amount of discharged power used is the largest. This can prevent the user of the power storage unit 11 from feeling dissatisfied due to the small amount of dischargeable power during usage hours when the user of the power storage unit 11 uses relatively electricity. In addition, in the example shown in FIG. 7, the smaller the remaining capacity of the power storage unit 12, the smaller the amount of available power for discharge is set to prevent deterioration of the power storage unit 12 due to overdischarge of the power storage unit 12. It has become.
　ステップＳ１０では、サーバ制御部２２は、ステップＳ８において算出した蓄電部１２の残容量、ステップＳ９において生成した制御マップを含む動作プログラム、及び、図示しないリアルタイムクロックから取得した現在時刻を蓄電制御部１８に送信する。 In step S10, the server control unit 22 transmits the remaining capacity of the power storage unit 12 calculated in step S8, the operation program including the control map generated in step S9, and the current time obtained from the real-time clock (not shown) to the power storage control unit 18. Send to.
　ステップＳ１１では、蓄電制御部１８は、サーバ制御部２２から動作プログラム等を受信すると、該動作プログラム等を蓄電記憶部１７に記憶する。 In step S<b>11 , upon receiving the operation program and the like from the server control unit 22 , the power storage control unit 18 stores the operation program and the like in the power storage storage unit 17 .
　ステップＳ１２では、蓄電制御部１８の判断部１９は、所定時間経過してもサーバ制御部２２からの応答がない、つまり、サーバ制御部２２から制御情報等が所定時間経過しても届かないため、蓄電制御部１８とサーバ制御部２２との間の通信異常が発生したと判断する。 In step S12, the determination unit 19 of the power storage control unit 18 determines that there is no response from the server control unit 22 even after a predetermined time has elapsed, that is, control information etc. have not arrived from the server control unit 22 even after the predetermined time has elapsed. , it is determined that a communication abnormality between the power storage control unit 18 and the server control unit 22 has occurred.
　ステップＳ１３では、蓄電制御部１８の異常時制御部２０は、ステップＳ１２において判断部１９がサーバ制御部２２との通信異常が発生したと判断すると、サーバ制御部２２から送信された制御情報に基づく蓄電ユニット１１の制御から蓄電記憶部１７に記憶された動作プログラムに基づく蓄電ユニット１１の制御に切り替える。つまり、サーバ制御部２２との通信異常が発生する前に蓄電側通信部１６が受信し、蓄電記憶部１７に記憶されている蓄電部１２の残容量、動作プログラム、及び、現在時刻に基づいて蓄電ユニット１１の制御処理を実行する。 In step S13, when the determination unit 19 determines that a communication abnormality with the server control unit 22 has occurred in step S12, the abnormality control unit 20 of the power storage control unit 18 performs a control operation based on the control information transmitted from the server control unit 22. The control of the power storage unit 11 is switched to the control of the power storage unit 11 based on the operation program stored in the power storage storage section 17. That is, based on the remaining capacity of the power storage unit 12, the operating program, and the current time, which are received by the power storage side communication unit 16 and stored in the power storage storage unit 17 before a communication abnormality with the server control unit 22 occurs, Control processing for the power storage unit 11 is executed.
　次に、図８を用いて異常時制御部２０が実行する具体的な制御処理について説明する。 Next, specific control processing executed by the abnormality control unit 20 will be described using FIG. 8.
　ステップＳ２１では、異常時制御部２０は、蓄電記憶部１７に記憶されている動作プログラムを読み出す。なお、次のステップＳ２１～Ｓ２５の各処理は、読み出した動作プログラムに基づいて実行される。 In step S21, the abnormality control unit 20 reads the operation program stored in the power storage storage unit 17. Note that each process in the next steps S21 to S25 is executed based on the read operation program.
　ステップＳ２２では、異常時制御部２０は、蓄電記憶部１７に記憶されている現在時刻から蓄電ユニット１１の使用時間帯を判断する。本実施形態では、朝（午前７時～午前１０時）、昼間（午前１０時～午後５時）、晩（午後５時～午後１１時）、夜間（午後１１時～午前７時）の４つの時間帯が予め設定されており、異常時制御部２０は、現在時刻がいずれの使用時間帯に含まれるかを判断するようになっている。 In step S22, the abnormality control unit 20 determines the usage time period of the power storage unit 11 from the current time stored in the power storage storage unit 17. In this embodiment, there are 4 types: morning (7 a.m. to 10 a.m.), daytime (10 a.m. to 5 p.m.), evening (5 p.m. to 11 p.m.), and nighttime (11 p.m. to 7 a.m.). Two time slots are set in advance, and the abnormality control unit 20 is configured to determine which usage time slot the current time is included in.
　ステップＳ２３では、異常時制御部２０は、図７に示す制御マップにおいて示された使用時間帯毎のラインの中からステップＳ２２において判断した使用時間帯に対応するラインを選択する。例えば、蓄電記憶部１７に記憶された現在時刻が午後７時の場合、ステップＳ２２では、使用時間帯が晩（午後５時～午後１１時）であると判断され、ステップＳ２３では、図７の制御マップに示された使用時間帯毎のラインから晩（午後５時～午後１１時）の時間帯のラインが選択される。 In step S23, the abnormality control unit 20 selects a line corresponding to the usage time zone determined in step S22 from among the lines for each usage time zone shown in the control map shown in FIG. For example, if the current time stored in the power storage storage unit 17 is 7:00 p.m., in step S22 it is determined that the usage time period is evening (5:00 p.m. to 11:00 p.m.), and in step S23, as shown in FIG. From the lines for each use time period shown on the control map, the line for the evening time period (5:00 pm to 11:00 pm) is selected.
　ステップＳ２４では、異常時制御部２０は、制御マップを用いて、選択された使用時間帯のラインと蓄電記憶部１７に記憶されている残容量とに基づき放電使用可能電力量を設定する。例えば、蓄電記憶部１７に記憶された蓄電部１２の残容量が図７の制御マップに示す残容量Ａである場合、ステップＳ２３において選択された晩の時間帯のライン上において横軸の残容量Ａに対応する縦軸の放電使用可能電力量Ｂが設定される。 In step S24, the abnormality control unit 20 uses the control map to set the usable amount of electric power to be discharged based on the line of the selected usage time period and the remaining capacity stored in the power storage storage unit 17. For example, if the remaining capacity of the electricity storage unit 12 stored in the electricity storage unit 17 is the remaining capacity A shown in the control map of FIG. 7, the remaining capacity on the horizontal axis is A discharge available power amount B on the vertical axis corresponding to A is set.
　ステップＳ２５では、異常時制御部２０は、ステップＳ２４において設定した放電使用可能電力量に基づき蓄電ユニット１１を制御する。例えば、蓄電ユニット１１の放電電力量がステップＳ２４において設定した放電使用可能電力量Ｂ以下となるように蓄電部１２及び電力変換部１４の電力変換動作が制御される。ステップＳ２５の処理の後はエンドに進み、しかる後、図５のステップＳ１４に進む。 In step S25, the abnormality control unit 20 controls the power storage unit 11 based on the amount of dischargeable power set in step S24. For example, the power conversion operations of the power storage unit 12 and the power conversion unit 14 are controlled so that the discharged power amount of the power storage unit 11 is equal to or less than the dischargeable usable power amount B set in step S24. After the processing in step S25, the process proceeds to end, and then proceeds to step S14 in FIG. 5.
　ステップＳ１４では、蓄電制御部１８は、蓄電部センサ１３及び電力変換部センサ１５から蓄電ユニット１１の状態情報を取得する。 In step S14, the power storage control unit 18 acquires state information of the power storage unit 11 from the power storage unit sensor 13 and the power conversion unit sensor 15.
　ステップＳ１５では、蓄電制御部１８は、取得した蓄電ユニット１１の状態情報をサーバ制御部２２に送信する。 In step S15, the power storage control unit 18 transmits the acquired state information of the power storage unit 11 to the server control unit 22.
　ステップＳ１６では、サーバ制御部２２は、蓄電ユニット１１の状態情報を受信すると、該状態情報から該蓄電ユニット１１の制御情報を設定し、蓄電制御部１８に送信する。 In step S<b>16 , upon receiving the state information of the power storage unit 11 , the server control unit 22 sets control information for the power storage unit 11 from the state information and transmits it to the power storage control unit 18 .
　ステップＳ１７では、サーバ制御部２２は、蓄電ユニット１１の状態情報や制御情報を管理用端末４に送信する。 In step S17, the server control unit 22 transmits the status information and control information of the power storage unit 11 to the management terminal 4.
　ステップＳ１８では、蓄電制御部１８は、サーバ制御部２２からの制御情報を受信すると、サーバ制御部２２との通信異常が復旧したと判断し、蓄電記憶部１７に記憶された動作プログラムに基づく蓄電ユニット１１の制御から、サーバ制御部２２から送信された制御情報に基づく蓄電ユニット１１の制御に切り替える。そして、再度、サーバ制御部２２との通信異常が発生するまで、サーバ制御部２２から随時送信される制御情報に基づいて蓄電ユニット１１の制御を行う。 In step S<b>18 , upon receiving the control information from the server control unit 22 , the power storage control unit 18 determines that the communication abnormality with the server control unit 22 has been recovered, and stores power based on the operation program stored in the power storage storage unit 17 . The control of the unit 11 is switched to the control of the power storage unit 11 based on the control information transmitted from the server control unit 22. Then, the power storage unit 11 is controlled based on the control information transmitted from the server control section 22 from time to time until a communication abnormality with the server control section 22 occurs again.
　以上より、本実施形態によると、災害等により蓄電ユニット１１とクラウドサーバ３との間の通信異常が発生した場合、蓄電ユニット１１がクラウドサーバ３からの制御情報を受信できなくなるが、通信異常時用の動作プログラムを予めクラウドサーバ３から受信しているので、該動作プログラムを用いて蓄電ユニット１１の動作を継続することができる。 As described above, according to the present embodiment, when a communication abnormality occurs between the power storage unit 11 and the cloud server 3 due to a disaster or the like, the power storage unit 11 becomes unable to receive control information from the cloud server 3; Since the operating program for the power storage unit 11 has been received from the cloud server 3 in advance, the operation of the power storage unit 11 can be continued using the operating program.
　また、クラウドサーバ３において蓄電ユニット１１の状態情報に応じて動作プログラムが生成されるようになる。複雑な処理が要求される動作プログラムの生成をクラウドサーバ３に担わせることにより、蓄電ユニット１１は、蓄電部１２における電圧等の状態情報の取得やクラウドサーバ３との通信等の最低限の機能を持つだけでよくなるので、蓄電ユニット１１の低コスト化が実現できる。 Additionally, an operation program is generated in the cloud server 3 according to the state information of the power storage unit 11. By having the cloud server 3 take charge of generating operation programs that require complex processing, the power storage unit 11 can perform minimum functions such as acquiring state information such as voltage in the power storage unit 12 and communicating with the cloud server 3. Since it is only necessary to hold the power storage unit 11, the cost of the power storage unit 11 can be reduced.
　また、蓄電部１２の使用時間帯や残容量に応じて異なる使用可能電力量が設定されるようになるので、例えば、蓄電ユニット１１のユーザーが比較的電気を使用する時間帯において放電使用可能電力量が低いことに起因してユーザーに不満感を与えてしまうことや、蓄電部１２の残容量が比較的多い状況において充電使用可能電力量が高いことに起因して蓄電部１２が過充電状態となってしまうのを防ぐことができる。 In addition, since different usable power amounts are set depending on the time of use and remaining capacity of the power storage unit 12, for example, the usable power to be discharged during a time period when the user of the power storage unit 11 uses relatively electricity. The power storage unit 12 may be in an overcharged state due to the low amount of charge, which may cause dissatisfaction to the user, or the power storage unit 12 may be in an overcharged state due to the high amount of chargeable power in a situation where the remaining capacity of the power storage unit 12 is relatively large. You can prevent this from happening.
　また、動作プログラムとともに、蓄電部１２の残容量や現在時刻の情報を蓄電ユニットが受信するようになる。このように、動作プログラムを動作させるのに必要な情報をクラウドサーバ３にて事前に作成しておくようになるので、蓄電ユニット１１が動作プログラムを用いて動作する際、残容量や現在時刻の情報を蓄電ユニット１１において自ら取得する必要がなくなる。したがって、蓄電ユニット１１の機能を最小限にできるので、蓄電ユニット１１の低コスト化が実現できる。 In addition, the power storage unit receives information on the remaining capacity of the power storage unit 12 and the current time together with the operation program. In this way, the information necessary to run the operation program is created in advance on the cloud server 3, so when the power storage unit 11 operates using the operation program, the remaining capacity and current time are There is no need for the power storage unit 11 to acquire the information itself. Therefore, since the functions of the power storage unit 11 can be minimized, the cost of the power storage unit 11 can be reduced.
　なお、本実施形態では、図６に示すように、蓄電ユニット１１の状態情報の履歴に基づく該蓄電ユニット１１の使用時間帯毎の放電使用電力量がサーバ記憶部２４に随時記憶されていたが、図９に一例で示す変形例のように、前記状態情報の履歴に基づく蓄電ユニット１１の曜日毎の放電使用電力量をサーバ記憶部２４に随時記憶するようにしてもよい。この場合、該曜日毎の放電使用電力量に基づいて、図１０に一例で示す変形例のように、蓄電部１２を使用する曜日及び蓄電部１２の残容量に応じて異なる放電使用可能電力量が設定された制御マップが生成される。ここで、図１０に示す制御マップでは、図９に示す、日曜日、土曜日、水曜日、金曜日、月曜日、木曜日、火曜日の順に放電使用電力量が多い使用履歴に基づいて設定されているので、蓄電ユニット１１のユーザーが比較的電気を使用する曜日において放電使用可能電力量が少ないことに起因してユーザーに不満感を与えてしまうことを防ぐことができる。 Note that in the present embodiment, as shown in FIG. 6, the amount of discharged power used for each usage time period of the power storage unit 11 based on the history of the state information of the power storage unit 11 is stored in the server storage unit 24 at any time. As in a modification example shown in FIG. 9, the amount of power discharged and used by the power storage unit 11 for each day of the week based on the history of the state information may be stored in the server storage unit 24 at any time. In this case, based on the amount of discharged power used for each day of the week, the amount of usable discharged power varies depending on the day of the week when the power storage unit 12 is used and the remaining capacity of the power storage unit 12, as in the modification example shown in FIG. 10. A control map with the settings is generated. Here, in the control map shown in FIG. 10, since the setting is based on the usage history in which the amount of discharged power used is large in the order of Sunday, Saturday, Wednesday, Friday, Monday, Thursday, and Tuesday shown in FIG. 9, the power storage unit It is possible to prevent the user from feeling dissatisfied due to the small amount of available discharged power on days of the week when the user of No. 11 uses electricity relatively.
　また、本実施形態では、制御マップは、図７に示すように、蓄電ユニット１１の使用時間帯及び蓄電部１２の残容量に応じて異なる放電使用可能量が設定されていたが、図１１に一例で示す変形例のように、蓄電ユニット１１の使用時間帯毎の使用履歴に基づいて蓄電ユニット１１の使用時間帯及び蓄電部１２の残容量に応じて異なる充電使用可能電力量を設定するようにしてもよい。これにより、例えば、蓄電ユニット１１のユーザーが比較的電気を充電する時間帯において充電使用可能電力量が少ないことに起因してユーザーに不満感を与えてしまうことや、蓄電部１２の残容量が比較的多い状況において充電使用可能電力量が多いことに起因して蓄電部１２が過充電状態となってしまうのを防ぐことができる。さらに、例えば、同一の蓄電部１２の残容量において、商用電源６の電力使用料金が比較的高い時間帯（例えば、昼間）では、比較的安い時間帯（例えば、夜間）よりも多くの充電使用可能電力量を設定することで、蓄電ユニット１１のユーザー等の電力使用料金負担を軽減することが可能となる。 In addition, in the present embodiment, as shown in FIG. 7, in the control map, different usable discharge amounts are set depending on the time of use of the power storage unit 11 and the remaining capacity of the power storage section 12, but as shown in FIG. As in the modified example shown as an example, the usable charging power amount is set to vary depending on the usage time of the power storage unit 11 and the remaining capacity of the power storage unit 12 based on the usage history for each usage time of the power storage unit 11. You can also do this. As a result, for example, the user of the power storage unit 11 may feel dissatisfied due to the small amount of power available for charging during a time period when the user of the power storage unit 11 is relatively charging electricity, or the remaining capacity of the power storage unit 12 may become low. It is possible to prevent power storage unit 12 from becoming overcharged due to a large amount of chargeable power in a relatively large amount of charge. Furthermore, for example, for the same remaining capacity of the power storage unit 12, more charging is used during a time period when the electricity usage rate of the commercial power source 6 is relatively high (e.g., during the day) than during a time period when it is relatively cheap (e.g., at night). By setting the possible amount of power, it is possible to reduce the burden of power usage charges on users of the power storage unit 11 and the like.
　また、本実施形態では、サーバ制御部２２は、蓄電ユニット１１が電気的に接続された施設２に発電機９が備えられているか否かの設置情報を考慮せずに動作プログラムを設定していたが、該設置情報を考慮して動作プログラムを設定するようにしてもよい。この場合、端末制御部２８は、操作入力部２６を用いて管理者が入力した発電機９の設置情報を受信して、該受信した発電機９の設置情報をサーバ制御部２２に送信することにより、該サーバ制御部２２が発電機９の設置情報を取得することができる。そして、サーバ制御部２２の生成部２３は、発電機９が備えられている施設２の場合、該施設２の停電時において発電機９が動作を開始するまで蓄電部１２から施設２に放電するように動作プログラムを生成する。このようにすることで、蓄電ユニット１１が設置されている施設２において停電が発生した場合、まず蓄電ユニット１１から施設２に電力が供給され、しかる後、発電機９が動作を開始すると、蓄電ユニット１１に代わり発電機９から施設２に電力が供給されるようになる。これにより、例えば、常時電力供給が必要な病院等の施設２において停電が発生した際、該施設２への電力供給を継続して行うことができる。 Furthermore, in the present embodiment, the server control unit 22 sets the operation program without considering installation information regarding whether or not the generator 9 is installed in the facility 2 to which the power storage unit 11 is electrically connected. However, the operating program may be set in consideration of the installation information. In this case, the terminal control unit 28 receives the installation information of the generator 9 input by the administrator using the operation input unit 26 and transmits the received installation information of the generator 9 to the server control unit 22. Accordingly, the server control unit 22 can acquire the installation information of the generator 9. In the case of a facility 2 equipped with a generator 9, the generation unit 23 of the server control unit 22 discharges electricity from the power storage unit 12 to the facility 2 during a power outage in the facility 2 until the generator 9 starts operating. Generate a working program as follows. By doing this, when a power outage occurs in the facility 2 where the power storage unit 11 is installed, power is first supplied from the power storage unit 11 to the facility 2, and then, when the generator 9 starts operating, the power storage Electric power is now supplied to the facility 2 from the generator 9 instead of the unit 11. Thereby, for example, when a power outage occurs in a facility 2 such as a hospital that requires constant power supply, power can be continuously supplied to the facility 2.
　また、本実施形態では、サーバ制御部２２は、図５のステップＳ６において蓄電ユニット１１の制御情報を蓄電制御部１８に送信した後、ステップＳ７において蓄電ユニット１１の状態情報や制御情報を管理用端末４に送信するようにしていたが、ステップＳ６とステップＳ７は同時に実行してもよく、或いは、ステップＳ７の後にステップＳ６を実行するようにしてもよい。 Further, in the present embodiment, after transmitting the control information of the power storage unit 11 to the power storage control unit 18 in step S6 of FIG. Although the information is transmitted to the terminal 4, step S6 and step S7 may be executed simultaneously, or step S6 may be executed after step S7.
　また、本実施形態では、蓄電ユニット１１は、蓄電記憶部１７を備えている例について説明したが、蓄電記憶部１７に代えて、或いは、該蓄電記憶部１７に加えて、レジスタやキャッシュメモリ等の記憶部を蓄電制御部１８に備えるようにしてもよい。なお、蓄電制御部１８に記憶部を備える場合、該記憶部にサーバ制御部２２から送信される蓄電部１２の残容量、制御マップを含む動作プログラム、及び、現在時刻が記憶される。 Further, in the present embodiment, an example has been described in which the power storage unit 11 includes the power storage storage section 17, but instead of or in addition to the power storage storage section 17, a register, a cache memory, etc. The power storage control unit 18 may be provided with a storage unit. Note that when the power storage control unit 18 includes a storage unit, the remaining capacity of the power storage unit 12 transmitted from the server control unit 22, an operation program including a control map, and the current time are stored in the storage unit.
　また、本実施形態では、蓄電ユニット１１は、蓄電制御部１８を備えている例について説明したが、蓄電部１２及び電力変換部１４それぞれに制御部を備えるようにしてもよい。 Furthermore, in the present embodiment, an example has been described in which the power storage unit 11 includes the power storage control section 18, but the power storage section 12 and the power conversion section 14 may each include a control section.
　また、本実施形態では、異常時制御部２０は、蓄電記憶部１７に記憶された蓄電部１２の残容量及び現在時刻を制御処理に用いていたが、異常時制御部２０において蓄電部センサ１３から取得した蓄電部１２の電流値の積算により該蓄電部１２の残容量を算出するようにしてもよく、また、蓄電制御部１８に備えられたリアルタイムクロックから現在時刻を取得するようにしてもよい。 Further, in the present embodiment, the abnormality control unit 20 uses the remaining capacity of the power storage unit 12 and the current time stored in the power storage storage unit 17 for control processing, but the abnormality control unit 20 uses the power storage unit sensor 13 The remaining capacity of the power storage unit 12 may be calculated by integrating the current value of the power storage unit 12 acquired from the power storage unit 12, or the current time may be obtained from a real-time clock provided in the power storage control unit 18. good.
　また、本実施形態では、制御マップは、図７に示すように、蓄電部１２の使用時間帯及び蓄電部１２の残容量の両方に応じて異なる使用可能電力量が設定されていたが、蓄電部１２の使用時間帯及び蓄電部１２の残容量のいずれか一方に応じて異なる使用可能電力量が設定するようにしてもよい。 Furthermore, in the present embodiment, as shown in FIG. 7, in the control map, the amount of usable power that can be used varies depending on both the usage time of the power storage unit 12 and the remaining capacity of the power storage unit 12. A different amount of usable power may be set depending on either the usage time of the unit 12 or the remaining capacity of the power storage unit 12.
　また、本実施形態では、サーバ制御部２２はサーバ側通信部２１を用いて、動作プログラムとともに、蓄電部１２の残容量及び現在時刻の両方を蓄電ユニット１１の蓄電制御部１８に送信していたが、動作プログラムとともに、蓄電部１２の残容量及び現在時刻のいずれか一方を蓄電ユニット１１の蓄電制御部１８に送信してもよく、或いは、動作プログラムとは分けて蓄電部１２の残容量及び現在時刻の少なくとも一方を蓄電制御部１８に送信するようにしてもよい。 Further, in the present embodiment, the server control unit 22 uses the server-side communication unit 21 to transmit both the remaining capacity of the power storage unit 12 and the current time to the power storage control unit 18 of the power storage unit 11 along with the operating program. However, either the remaining capacity of the power storage unit 12 or the current time may be transmitted to the power storage control unit 18 of the power storage unit 11 along with the operation program, or the remaining capacity of the power storage unit 12 and the current time may be transmitted separately from the operation program. At least one of the current times may be transmitted to the power storage control unit 18.
　また、本実施形態では、サーバ制御部２２は、制御マップを含む動作プログラムを蓄電制御部１８に送信する例について説明したが、蓄電記憶部１７に制御マップを除く動作プログラムを記憶しておき、サーバ制御部２２は制御マップのみを生成し、蓄電制御部１８に送信するようにしてもよい。 Further, in the present embodiment, an example has been described in which the server control unit 22 transmits the operation program including the control map to the power storage control unit 18, but the operation program excluding the control map is stored in the power storage storage unit 17. The server control unit 22 may generate only a control map and transmit it to the power storage control unit 18.
＜第２の実施形態＞
　次に、本発明の第２の実施形態について説明する。なお、第２の実施形態の説明において、上述した説明における同一または同質の構成については同一の参照符号を付し、重複した説明を適宜省略する。 <Second embodiment>
Next, a second embodiment of the present invention will be described. In the description of the second embodiment, the same or homogeneous configurations in the above description will be denoted by the same reference numerals, and redundant description will be omitted as appropriate.
　上記の背景技術に対して、例えば、蓄電ユニットにおいてショート状態や異常温度状態などの異常状態が発生した場合、安全上の観点から蓄電ユニットの動作を迅速に緊急停止させることが望ましい。しかし、特許文献１の如き管理システムでは、蓄電ユニットの異常状態情報を蓄電ユニットからサーバに送信し、該異常状態情報を受信したサーバからの停止指令が蓄電ユニットに届くのを待つ必要があるので、蓄電ユニットの緊急停止の迅速化には課題があった。 Regarding the above-mentioned background art, for example, when an abnormal condition such as a short circuit or an abnormal temperature condition occurs in a power storage unit, it is desirable to immediately emergency stop the operation of the power storage unit from a safety standpoint. However, in the management system such as Patent Document 1, it is necessary to transmit abnormal state information of the power storage unit from the power storage unit to the server and wait for a stop command from the server that has received the abnormal state information to reach the power storage unit. However, there was a problem in speeding up the emergency shutdown of the energy storage unit.
　本実施形態の目的とするところは、蓄電ユニットの異常状態の発生時において該蓄電ユニットの動作の緊急停止を迅速に行うことが可能な管理システムを提供することにある。 The purpose of this embodiment is to provide a management system that can quickly stop the operation of a power storage unit when an abnormal state occurs in the power storage unit.
　第２の実施形態に係る管理システムとしては、第１の実施形態で説明した管理システム１を適用できる。 As the management system according to the second embodiment, the management system 1 described in the first embodiment can be applied.

The facility 2 according to this embodiment is different from the facility 2 according to the first embodiment and does not include the power storage storage section 17. Furthermore, the power storage control unit 18 according to the present embodiment includes a determination unit 19A and an emergency stop unit 20A.
　判断部１９Ａ及び緊急停止部２０Ａは、クラウドサーバ３による制御とは独立して動作可能、つまり、クラウドサーバ３から送信される制御情報から独立して動作可能となっている。 The determination unit 19A and the emergency stop unit 20A can operate independently of the control by the cloud server 3, that is, they can operate independently of the control information transmitted from the cloud server 3.
　判断部１９Ａは、蓄電部センサ１３及び電力変換部センサ１５で取得した状態情報に基づいて蓄電ユニット１１の動作を緊急停止させる必要がある異常状態、つまり、蓄電部１２や電力変換部１４においてショート状態、異常温度状態、及び、故障状態が発生しているかどうかを判断するように構成されている。 Judgment unit 19A detects an abnormal state in which the operation of power storage unit 11 needs to be stopped urgently based on the status information acquired by power storage unit sensor 13 and power conversion unit sensor 15, that is, a short circuit in power storage unit 12 or power conversion unit 14. The system is configured to determine whether a condition, an abnormal temperature condition, and a failure condition are occurring.
　緊急停止部２０Ａは、判断部１９Ａにおいて蓄電部１２や電力変換部１４が異常状態であると判断されたときに、クラウドサーバ３からの停止指令を待つことなく蓄電ユニット１１の動作を緊急停止、つまり、蓄電部１２の充放電動作や電力変換部１４の電力変換動作を緊急停止するように構成されている。 When the determination unit 19A determines that the power storage unit 12 or the power conversion unit 14 is in an abnormal state, the emergency stop unit 20A urgently stops the operation of the power storage unit 11 without waiting for a stop command from the cloud server 3. That is, it is configured to emergency stop the charging/discharging operation of the power storage unit 12 and the power conversion operation of the power conversion unit 14.
　次に、図１３を用いて第２の実施形態に係るクラウドサーバ３について説明する。 Next, the cloud server 3 according to the second embodiment will be described using FIG. 13.
　本実施形態に係るサーバ制御部２２は、図示しないプロセッサを備えている。本実施形態に係るサーバ制御部２２は、リアルタイムクロックを備えていなくてもよい。 The server control unit 22 according to this embodiment includes a processor (not shown). The server control unit 22 according to this embodiment does not need to include a real-time clock.
　さらに、サーバ制御部２２は、生成部２３に代えて再開指令部２３Ａを備えている。該再開指令部２３Ａは、蓄電ユニット１１が緊急停止部２０Ａにより停止状態である場合において蓄電ユニット１１の異常状態が解消した際、蓄電ユニット１１の動作の再開を指令する制御情報を蓄電ユニット１１に送信するように構成されている。 Furthermore, the server control unit 22 includes a restart command unit 23A instead of the generation unit 23. The restart command unit 23A sends control information to the power storage unit 11 to instruct the power storage unit 11 to resume operation when the abnormal state of the power storage unit 11 is resolved when the power storage unit 11 is stopped by the emergency stop unit 20A. configured to send.
　記憶部２４Ａは、メモリー等の記憶装置であり、サーバ制御部２２と接続されている。該記憶部２４Ａには、例えば、蓄電ユニット１１の時間帯及び曜日別の充放電情報、蓄電ユニット１１から受信した状態情報、サーバ制御部２２において算出或いは予測した充電率等の情報、及び、セルバランス制御やモジュールバランス制御等の実施情報が記憶されている。 The storage unit 24A is a storage device such as a memory, and is connected to the server control unit 22. The storage unit 24A stores, for example, charging/discharging information of the power storage unit 11 by time of day and day of the week, status information received from the power storage unit 11, information such as the charging rate calculated or predicted by the server control unit 22, and information about the cell. Implementation information such as balance control and module balance control is stored.
　第２の実施形態に係る管理用端末としては、第１の実施形態で説明した管理用端末４を適用できる。 As the management terminal according to the second embodiment, the management terminal 4 described in the first embodiment can be applied.
　次に、図１４及び図１５を用いて第２の実施形態に係る管理システム１の動作について説明する。 Next, the operation of the management system 1 according to the second embodiment will be described using FIGS. 14 and 15.
　まず、図１４を用いてクラウドサーバ３のサーバ制御部２２が蓄電ユニット１１の充電を停止させる場合の動作について説明する。 First, the operation when the server control unit 22 of the cloud server 3 stops charging the power storage unit 11 will be described using FIG. 14.
　ステップＳ３１では、蓄電ユニット１１の蓄電制御部１８は、蓄電部センサ１３及び電力変換部センサ１５から蓄電部１２及び電力変換部１４（蓄電ユニット１１）の状態情報を取得する。 In step S31, the power storage control unit 18 of the power storage unit 11 acquires status information of the power storage unit 12 and the power conversion unit 14 (power storage unit 11) from the power storage unit sensor 13 and the power conversion unit sensor 15.
　ステップＳ３２では、蓄電制御部１８は、取得した蓄電ユニット１１の状態情報をクラウドサーバ３に送信する。 In step S32, the power storage control unit 18 transmits the acquired state information of the power storage unit 11 to the cloud server 3.
　ステップＳ３３では、クラウドサーバ３のサーバ制御部２２は、蓄電ユニット１１の状態情報を受信すると、該状態情報から該蓄電ユニット１１の制御情報を設定し、蓄電制御部１８に送信する。 In step S33, upon receiving the state information of the power storage unit 11, the server control unit 22 of the cloud server 3 sets control information for the power storage unit 11 from the state information and transmits it to the power storage control unit 18.
　ステップＳ３４では、サーバ制御部２２は、蓄電ユニット１１の状態情報や制御情報を管理用端末４に送信する。該管理用端末４では、端末制御部２８が受信した蓄電ユニット１１の状態情報や制御情報を表示部２７に表示させる。 In step S34, the server control unit 22 transmits the status information and control information of the power storage unit 11 to the management terminal 4. In the management terminal 4, the status information and control information of the power storage unit 11 received by the terminal control section 28 are displayed on the display section 27.
　ステップＳ３５では、サーバ制御部２２は、受信した蓄電ユニット１１の状態情報から蓄電ユニット１１の蓄電部１２の残容量を算出する。本実施形態では、残容量は、蓄電ユニット１１の状態情報における電流値を積算することにより算出する。 In step S35, the server control unit 22 calculates the remaining capacity of the power storage section 12 of the power storage unit 11 from the received state information of the power storage unit 11. In this embodiment, the remaining capacity is calculated by integrating the current values in the state information of the power storage unit 11.
　ステップＳ３６では、サーバ制御部２２は、ステップＳ３５において算出した蓄電部１２の残容量が上限値を超えていることから、過充電のおそれがあるため、蓄電ユニット１１に充電の停止を指令する制御情報を送信する。本実施形態では、蓄電部１２の残容量の規定範囲は、例えば、２５～９０％の範囲に設定されており、該残容量が規定範囲内にある場合には充放電の停止指令を行わず、上限値（例えば、９０％）を超えている場合には充電の停止指令を行い、下限値（例えば、２５％）を下回っている場合には放電の停止指令を行うようになっている。 In step S36, since the remaining capacity of the power storage unit 12 calculated in step S35 exceeds the upper limit value, there is a risk of overcharging, so the server control unit 22 performs control to instruct the power storage unit 11 to stop charging. Submit information. In this embodiment, the specified range of the remaining capacity of the power storage unit 12 is set to, for example, a range of 25% to 90%, and when the remaining capacity is within the specified range, no charge/discharge stop command is issued. If it exceeds an upper limit value (for example, 90%), a command to stop charging is issued, and if it is below a lower limit value (for example, 25%), a command to stop discharging is issued.
　ステップＳ３７では、蓄電制御部１８は、サーバ制御部２２から制御情報を受信すると、該制御情報に基づき蓄電ユニット１１の充電を停止する。なお、蓄電ユニット１１の放電は可能であり、施設２の負荷８に蓄電ユニット１１から電力供給が可能である。 In step S37, upon receiving the control information from the server control unit 22, the power storage control unit 18 stops charging the power storage unit 11 based on the control information. Note that the power storage unit 11 can be discharged, and power can be supplied from the power storage unit 11 to the load 8 of the facility 2.
　ステップＳ３８では、蓄電制御部１８は、蓄電部センサ１３及び電力変換部センサ１５から蓄電ユニット１１の状態情報を取得する。 In step S38, the power storage control unit 18 acquires state information of the power storage unit 11 from the power storage unit sensor 13 and the power conversion unit sensor 15.
　ステップＳ３９では、蓄電制御部１８は、取得した蓄電ユニット１１の状態情報をサーバ制御部２２に送信する。 In step S39, the power storage control unit 18 transmits the acquired state information of the power storage unit 11 to the server control unit 22.
　ステップＳ４０では、サーバ制御部２２は、受信した蓄電ユニット１１の状態情報から蓄電ユニット１１が充電を停止している状態であることを検出すると、該蓄電ユニット１１が充電停止状態であることを端末制御部２８に通知する。 In step S40, when the server control unit 22 detects that the power storage unit 11 is in a charging stopped state from the received state information of the power storage unit 11, the server control unit 22 informs the terminal that the power storage unit 11 is in a charging stopped state. The control unit 28 is notified.
　ステップＳ４１では、蓄電制御部１８は、蓄電部センサ１３及び電力変換部センサ１５から蓄電ユニット１１の状態情報を取得する。 In step S41, the power storage control unit 18 acquires state information of the power storage unit 11 from the power storage unit sensor 13 and the power conversion unit sensor 15.
　ステップＳ４２では、蓄電制御部１８は、取得した蓄電ユニット１１の状態情報をサーバ制御部２２に送信する。 In step S42, the power storage control unit 18 transmits the acquired state information of the power storage unit 11 to the server control unit 22.
　ステップＳ４３では、サーバ制御部２２は、蓄電ユニット１１の蓄電部１２の残容量を算出する。本実施形態では、サーバ制御部２２が受信した状態情報に含まれる電流値が０以外の場合、つまり、蓄電ユニット１１の充放電が行われている場合には蓄電ユニット１１の残容量を算出する一方、電流値が０の場合、つまり、蓄電ユニット１１の充放電が停止されている場合には蓄電ユニット１１の残容量を算出しないようになっている。 In step S43, the server control unit 22 calculates the remaining capacity of the power storage section 12 of the power storage unit 11. In this embodiment, when the current value included in the status information received by the server control unit 22 is other than 0, that is, when the power storage unit 11 is being charged and discharged, the remaining capacity of the power storage unit 11 is calculated. On the other hand, when the current value is 0, that is, when charging and discharging of the power storage unit 11 is stopped, the remaining capacity of the power storage unit 11 is not calculated.
　ステップＳ４４では、サーバ制御部２２は、ステップＳ１３において算出した蓄電部１２の残容量が上限値を下回っていることから、過充電のおそれがないため、充電の再開を指令する制御情報を蓄電ユニット１１に送信する。なお、蓄電部１２の残容量が上限値を超えている場合には充電の再開を指令せず、充電の停止を継続するようになっている。 In step S44, since the remaining capacity of the power storage unit 12 calculated in step S13 is below the upper limit value, there is no risk of overcharging, so the server control unit 22 transmits control information instructing the power storage unit to restart charging. Send to 11. Note that, if the remaining capacity of power storage unit 12 exceeds the upper limit value, restart of charging is not commanded, and charging continues to be stopped.
　ステップＳ４５では、蓄電制御部１８は、サーバ制御部２２から制御情報を受信すると、該制御情報に基づき蓄電ユニット１１の充電を再開する。 In step S45, upon receiving the control information from the server control unit 22, the power storage control unit 18 resumes charging the power storage unit 11 based on the control information.
　ステップＳ４６では、蓄電制御部１８は、蓄電部センサ１３及び電力変換部センサ１５から蓄電ユニット１１の状態情報を取得する。 In step S46, the power storage control unit 18 acquires state information of the power storage unit 11 from the power storage unit sensor 13 and the power conversion unit sensor 15.
　ステップＳ４７では、蓄電制御部１８は、取得した蓄電ユニット１１の状態情報をサーバ制御部２２に送信する。 In step S47, the power storage control unit 18 transmits the acquired status information of the power storage unit 11 to the server control unit 22.
　ステップＳ４８では、サーバ制御部２２は、蓄電ユニット１１の状態情報を受信すると、該状態情報から該蓄電ユニット１１の制御情報を設定し、蓄電制御部１８に送信する。 In step S<b>48 , upon receiving the state information of the power storage unit 11 , the server control unit 22 sets control information for the power storage unit 11 from the state information and transmits it to the power storage control unit 18 .
　ステップＳ４９では、サーバ制御部２２は、受信した蓄電ユニット１１の状態情報から蓄電ユニット１１の充電再開を検出すると、該蓄電ユニット１１の充電が再開されたことを端末制御部２８に通知する。 In step S49, when the server control unit 22 detects the restart of charging of the power storage unit 11 from the received status information of the power storage unit 11, it notifies the terminal control unit 28 that charging of the power storage unit 11 has been restarted.
　次に、図１５を用いて蓄電ユニット１１の蓄電制御部１８が蓄電ユニット１１を緊急停止させる場合の動作について説明する。なお、ステップＳ５１～Ｓ５４は、図１４のステップＳ３１～Ｓ３４と同様であるため、説明を省略する。 Next, the operation when the power storage controller 18 of the power storage unit 11 makes an emergency stop of the power storage unit 11 will be described using FIG. 15. Note that steps S51 to S54 are the same as steps S31 to S34 in FIG. 14, so the explanation will be omitted.
　ステップＳ５５では、蓄電制御部１８の判断部１９Ａは、ステップＳ５１で取得した蓄電部センサ１３及び電力変換部センサ１５の状態情報から蓄電ユニット１１の動作を緊急停止させる必要がある異常状態が発生していると判断する。本実施形態では、判断部１９Ａは、蓄電ユニット１１の異常状態情報を蓄電ユニット１１からクラウドサーバ３に送信し、該異常状態情報を受信したクラウドサーバ３から停止指令が蓄電ユニット１１に届くまでに所定時間（例えば、１０秒程度）かかることを考慮し、該所定時間を待つことなく直ちに蓄電ユニット１１の緊急停止が必要な異常状態であるか否か、つまり、蓄電部１２や電力変換部１４においてショート状態、異常温度状態、及び、故障状態が発生しているか否かを判断するように構成されている。 In step S55, the determination unit 19A of the power storage control unit 18 determines whether an abnormal state has occurred that requires an emergency stop of the operation of the power storage unit 11, based on the state information of the power storage unit sensor 13 and the power conversion unit sensor 15 acquired in step S51. It is determined that In the present embodiment, the determination unit 19A transmits abnormal state information of the power storage unit 11 from the power storage unit 11 to the cloud server 3, and waits until a stop command reaches the power storage unit 11 from the cloud server 3 that has received the abnormal state information. Considering that it will take a predetermined time (for example, about 10 seconds), it is necessary to determine whether or not there is an abnormal state that requires an immediate emergency stop of the power storage unit 11 without waiting for the predetermined time, that is, whether the power storage unit 12 or the power conversion unit 14 is in an abnormal state. The apparatus is configured to determine whether a short-circuit condition, an abnormal temperature condition, or a failure condition has occurred in the apparatus.
　ステップＳ５６では、蓄電制御部１８の緊急停止部２０Ａは、ステップＳ５５において蓄電ユニット１１が異常状態であると判断されると、クラウドサーバ３からの停止指令を待つことなく蓄電ユニット１１の動作を緊急停止、つまり、蓄電部１２の充放電動作及び電力変換部１４の電力変換動作を緊急停止する。これにより、例えば、蓄電部１２や電力変換部１４がショート状態の場合、蓄電ユニット１１内に短絡電流が流れるのが防止でき、また、蓄電部１２や電力変換部１４が異常温度状態の場合、蓄電ユニット１１が過度に温度上昇するのを防ぐことが可能となる。 In step S56, when it is determined that the power storage unit 11 is in an abnormal state in step S55, the emergency stop unit 20A of the power storage control unit 18 stops the operation of the power storage unit 11 as an emergency without waiting for a stop command from the cloud server 3. In other words, the charging/discharging operation of the power storage unit 12 and the power conversion operation of the power conversion unit 14 are stopped urgently. As a result, for example, when the power storage unit 12 or the power conversion unit 14 is in a short-circuit state, a short circuit current can be prevented from flowing into the power storage unit 11, and if the power storage unit 12 or the power conversion unit 14 is in an abnormal temperature state, It becomes possible to prevent the temperature of power storage unit 11 from rising excessively.
　ステップＳ５７では、蓄電制御部１８は、蓄電部センサ１３及び電力変換部センサ１５から蓄電ユニット１１の状態情報を取得する。 In step S57, the power storage control unit 18 acquires state information of the power storage unit 11 from the power storage unit sensor 13 and the power conversion unit sensor 15.
　ステップＳ５８では、蓄電制御部１８は、取得した蓄電ユニット１１の状態情報をサーバ制御部２２に送信する。 In step S58, the power storage control unit 18 transmits the acquired state information of the power storage unit 11 to the server control unit 22.
　ステップＳ５９では、サーバ制御部２２は、受信した蓄電ユニット１１の状態情報から蓄電ユニット１１が緊急停止している状態であることを検出すると、該蓄電ユニット１１が緊急停止状態であることを端末制御部２８に通知する。 In step S59, when detecting that the power storage unit 11 is in an emergency stop state from the received state information of the power storage unit 11, the server control unit 22 controls the terminal to detect that the power storage unit 11 is in an emergency stop state. Department 28.
　ステップＳ６０では、蓄電制御部１８は、蓄電部センサ１３及び電力変換部センサ１５により蓄電ユニット１１の状態情報を取得する。 In step S60, the power storage control unit 18 acquires state information of the power storage unit 11 using the power storage unit sensor 13 and the power conversion unit sensor 15.
　ステップＳ６１では、蓄電制御部１８は、取得した蓄電ユニット１１の状態情報をサーバ制御部２２に送信する。 In step S61, the power storage control unit 18 transmits the acquired state information of the power storage unit 11 to the server control unit 22.
　ステップＳ６２では、サーバ制御部２２は、受信した蓄電ユニット１１の状態情報から蓄電ユニット１１の充放電を再開可能と判断する。本実施形態では、蓄電ユニット１１における蓄電部１２及び電力変換部１４の電圧、電流、温度が規定の範囲内にある場合に再開可能と判断する一方、該電圧等が規定の範囲内にない場合は再開可能ではないと判断するようになっている。 In step S62, the server control unit 22 determines that charging and discharging of the power storage unit 11 can be resumed from the received status information of the power storage unit 11. In the present embodiment, it is determined that restart is possible when the voltage, current, and temperature of the power storage section 12 and power conversion section 14 in the power storage unit 11 are within the specified range, but when the voltage, etc. are not within the specified range. It is now determined that it is not possible to restart.
　ステップＳ６３では、サーバ制御部２２の再開指令部２３Ａは、蓄電ユニット１１の動作の再開を指令する制御情報を送信する。つまり、蓄電部１２の充放電動作や電力変換部１４の電力変換動作の再開を指令する。 In step S63, the restart command unit 23A of the server control unit 22 transmits control information that commands the power storage unit 11 to restart its operation. In other words, it instructs the power storage unit 12 to restart the charging/discharging operation and the power conversion unit 14 to restart the power conversion operation.
　ステップＳ６４では、蓄電制御部１８は、サーバ制御部２２からの再開指令に基づいて蓄電ユニット１１の動作（充放電）を再開させる。つまり、蓄電部１２の充放電動作や電力変換部１４の電力変換動作を再開する。 In step S64, the power storage control unit 18 restarts the operation (charging and discharging) of the power storage unit 11 based on the restart command from the server control unit 22. That is, the charging/discharging operation of the power storage unit 12 and the power conversion operation of the power conversion unit 14 are restarted.
　ステップＳ６５は、蓄電制御部１８は、蓄電部センサ１３及び電力変換部センサ１５から蓄電ユニット１１の状態情報を取得する。 In step S65, the power storage control unit 18 acquires state information of the power storage unit 11 from the power storage unit sensor 13 and the power conversion unit sensor 15.
　ステップＳ６６では、蓄電制御部１８は、取得した蓄電ユニット１１の状態情報をサーバ制御部２２に送信する。 In step S66, the power storage control unit 18 transmits the acquired state information of the power storage unit 11 to the server control unit 22.
　ステップＳ６７では、サーバ制御部２２は、蓄電ユニット１１の状態情報を受信すると、該状態情報から該蓄電ユニット１１の制御情報を設定し、蓄電制御部１８に送信する。 In step S67, upon receiving the state information of the power storage unit 11, the server control unit 22 sets control information for the power storage unit 11 from the state information and transmits it to the power storage control unit 18.
　ステップＳ６８では、サーバ制御部２２は、取得した蓄電ユニット１１の状態情報から該蓄電ユニット１１の充放電の再開を検出し、端末制御部２８に蓄電ユニット１１の充放電が再開されたことを通知する。 In step S68, the server control unit 22 detects the restart of charging and discharging of the power storage unit 11 from the acquired status information of the power storage unit 11, and notifies the terminal control unit 28 that the charging and discharging of the power storage unit 11 has been resumed. do.
　以上より、本実施形態によると、例えば、蓄電ユニット１１においてショート状態や異常温度状態などの異常状態が発生した場合、クラウドサーバ３からの停止指令を待つことなく蓄電ユニット１１の動作が緊急停止されるようになる。これにより、特許文献１の如き管理システムのようにクラウドサーバからの停止指令を蓄電ユニットに届くのに時間がかかってしまうことで、該蓄電ユニットの緊急停止の迅速性が損なわれるのを防ぐことができる。 As described above, according to the present embodiment, for example, when an abnormal state such as a short circuit state or an abnormal temperature state occurs in the power storage unit 11, the operation of the power storage unit 11 is stopped immediately without waiting for a stop command from the cloud server 3. Become so. This prevents the speed of emergency stop of the power storage unit from being impaired due to the time it takes for a stop command from the cloud server to reach the power storage unit, as in the management system of Patent Document 1. I can do it.
　また、蓄電ユニット１１において異常状態が発生した場合、蓄電ユニット１１の充放電が停止されるようになる。これにより、例えば、蓄電ユニット１１内を短絡電流が流れることで、蓄電ユニット１１内の機器が破損してしまうのを防ぐことができる。 Furthermore, when an abnormal state occurs in the power storage unit 11, charging and discharging of the power storage unit 11 is stopped. Thereby, for example, it is possible to prevent equipment in the power storage unit 11 from being damaged due to a short circuit current flowing through the power storage unit 11.
　また、例えば、蓄電ユニット１１において異常状態が発生し、かつ、スイッチ等の故障で蓄電部１２の充放電動作を停止できない場合、電力変換部１４の電力変換動作が停止されることで、蓄電ユニット１１の充放電を停止することができる。また、例えば、蓄電ユニット１１において異常状態が発生した場合、蓄電部１２の充放電動作及び電力変換部１４の電力変換動作の両方が停止されることで、確実に蓄電ユニット１１の充放電を停止することができる。 Further, for example, if an abnormal state occurs in the power storage unit 11 and the charging/discharging operation of the power storage unit 12 cannot be stopped due to a failure of a switch or the like, the power conversion operation of the power conversion unit 14 is stopped, so that the power storage unit 11 charging/discharging can be stopped. Further, for example, when an abnormal state occurs in the power storage unit 11, both the charging/discharging operation of the power storage unit 12 and the power conversion operation of the power conversion unit 14 are stopped, thereby ensuring that the charging/discharging of the power storage unit 11 is stopped. can do.
　また、蓄電ユニット１１においてショート状態、異常温度状態、及び、故障状態のうち少なくとも１つが発生した場合、蓄電ユニット１１の動作が停止されるようになる。これにより、例えば、蓄電ユニット１１が過度に温度上昇してしまうことで、蓄電ユニット１１内の機器が破損してしまうのを防ぐことができる。 Further, when at least one of a short circuit state, an abnormal temperature state, and a failure state occurs in the power storage unit 11, the operation of the power storage unit 11 is stopped. Thereby, for example, it is possible to prevent equipment in the power storage unit 11 from being damaged due to an excessive temperature rise in the power storage unit 11.
　また、蓄電ユニット１１の動作が停止した後は、クラウドサーバ３からの再開指令を受けてから蓄電ユニット１１を再び作動させるようになる。これにより、例えば、蓄電ユニット１１の異常状態が解消したことをクラウドサーバ３側で判断した後に、蓄電ユニット１１の作動が再開されるようになるので、該蓄電ユニット１１の異常状態が継続している際に誤って蓄電ユニット１１の作動が再開されてしまう等の事態を回避することができる。 Furthermore, after the operation of the power storage unit 11 is stopped, the power storage unit 11 is started to operate again after receiving a restart command from the cloud server 3. As a result, for example, after the cloud server 3 determines that the abnormal state of the power storage unit 11 has been resolved, the operation of the power storage unit 11 is restarted, so that the abnormal state of the power storage unit 11 continues. It is possible to avoid a situation where the operation of the power storage unit 11 is erroneously restarted when the power storage unit 11 is in use.
　また、クラウドサーバ３において蓄電部１２の残容量（充電率）算出等の複雑な処理が行われるようになる。複雑な処理をクラウドサーバ３に担わせることにより、蓄電ユニット１１は、蓄電部１２における電圧等の状態情報の取得や異常状態時の処理等の最低限の機能を担うだけとなるので、蓄電ユニット１１の低コスト化が実現できる。 Additionally, complicated processing such as calculating the remaining capacity (charging rate) of the power storage unit 12 will be performed in the cloud server 3. By having the cloud server 3 take charge of complex processing, the power storage unit 11 only takes on the minimum functions such as obtaining status information such as voltage in the power storage unit 12 and processing when an abnormal state occurs. 11 cost reductions can be realized.
　なお、本実施形態では、図１４のステップＳ３５においてサーバ制御部２２が算出した蓄電部１２の残容量から蓄電ユニット１１の充電を停止させる判断をし、ステップＳ３６において該蓄電ユニット１１に充電停止を指令していたが、管理者が操作入力部２６を用いて蓄電ユニット１１の充電を停止させる操作をした場合、端末制御部２８がサーバ制御部２２を経由して蓄電ユニット１１の充電の停止を指令するようにしてもよい。この場合、管理者が操作入力部２６を用いて蓄電ユニット１１の充電再開操作をすることで、端末制御部２８がサーバ制御部２２を経由して蓄電ユニット１１の充電の再開を指令するようにしてもよく、また、サーバ制御部２２が蓄電ユニット１１に充電の再開を指令するようにしてもよい。 In this embodiment, the server control unit 22 determines to stop charging the power storage unit 11 based on the calculated remaining capacity of the power storage unit 12 in step S35 of FIG. 14, and instructs the power storage unit 11 to stop charging in step S36. However, if the administrator performs an operation to stop charging the power storage unit 11 using the operation input unit 26, the terminal control unit 28 issues a command to stop charging the power storage unit 11 via the server control unit 22. It is also possible to give a command. In this case, when the administrator performs an operation to restart charging of the power storage unit 11 using the operation input unit 26, the terminal control unit 28 instructs the restart of charging of the power storage unit 11 via the server control unit 22. Alternatively, the server control unit 22 may instruct the power storage unit 11 to restart charging.
　また、本実施形態では、図１５のステップＳ６２においてサーバ制御部２２が蓄電ユニット１１の充放電の再開が可能と判断をし、ステップＳ３３において該蓄電ユニット１１に充放電の再開を指令していたが、管理者が操作入力部２６を用いて蓄電ユニット１１に充放電を再開させる操作をした場合、端末制御部２８がサーバ制御部２２を経由して蓄電ユニット１１に充放電の再開を指令するようにしてもよい。このようにすることで、管理者は、クラウドサーバ３を経由して蓄電ユニット１１を遠隔制御することができる。 Further, in the present embodiment, the server control unit 22 determines in step S62 of FIG. 15 that it is possible to resume charging and discharging the power storage unit 11, and instructs the power storage unit 11 to restart charging and discharging in step S33. However, when the administrator uses the operation input unit 26 to cause the power storage unit 11 to resume charging and discharging, the terminal control unit 28 instructs the power storage unit 11 to resume charging and discharging via the server control unit 22. You can do it like this. By doing so, the administrator can remotely control the power storage unit 11 via the cloud server 3.
　また、本実施形態では、サーバ制御部２２は、図１４のステップＳ３３において蓄電ユニット１１の制御情報を蓄電制御部１８に送信した後、ステップＳ３４において蓄電ユニット１１の状態情報や制御情報を管理用端末４に送信するようにしていたが、ステップＳ３３とステップＳ３４は同時に実行してもよく、或いは、ステップＳ３４の後にステップＳ３３を実行するようにしてもよい。 Further, in the present embodiment, after transmitting the control information of the power storage unit 11 to the power storage control unit 18 in step S33 of FIG. Although the information is transmitted to the terminal 4, step S33 and step S34 may be executed simultaneously, or step S33 may be executed after step S34.
　また、本実施形態では、サーバ制御部２２は、図１４のステップＳ３６及びステップＳ４４において蓄電ユニット１１の充電の停止及びその再開を指令していたが、蓄電ユニット１１の放電の停止及びその再開、或いは、充放電の停止及びその再開を指令するようにしてもよい。 Furthermore, in the present embodiment, the server control unit 22 instructs to stop and restart charging of the power storage unit 11 in steps S36 and S44 of FIG. Alternatively, a command may be given to stop and restart charging and discharging.

　また、本実施形態では、緊急停止部２０Ａは、蓄電部１２の充放電動作及び電力変換部１４の電力変換動作を緊急停止するようにしていたが、蓄電部１２の充放電動作及び電力変換部１４の電力変換動作のうちいずれか一方を緊急停止するようにしてもよく、また、電力変換部１４における昇圧動作を停止することや蓄電ユニット１１における蓄電部１２及び電力変換部１４以外の機器の動作を停止することにより、蓄電ユニット１１の動作を停止するようにしてもよい。 Furthermore, in the present embodiment, the emergency stop unit 20A is configured to emergency stop the charging/discharging operation of the power storage unit 12 and the power conversion operation of the power conversion unit 14; It is also possible to emergency stop one of the 14 power conversion operations, or to stop the step-up operation in the power conversion section 14 or to stop the voltage boosting operation in the power conversion section 14 or to stop the voltage boosting operation in the power storage unit 11 other than the power storage section 12 and the power conversion section 14. The operation of the power storage unit 11 may be stopped by stopping the operation.
