FIG. 1 shows a power supply system 100 according to the present invention, a user communication terminal 200, and a load 300 such as an electric device. As shown in FIG. 1, the power supply system 100 includes a power source 110 including a fuel cell 111, a solar cell 112, and a storage battery 113, a control unit 120 that measures the power supplied from the power source 110 and distributes the power to the load 300. A fuel storage unit 130 such as an LPG gas cylinder that supplies fuel to the fuel cell 111 and a scale 131 for measuring the weight of the fuel storage unit 130 are provided.
制御ユニット１２０は、燃料電池１１１に接続された第１の計測部１２１と、太陽電池１１２に接続された第２の計測部１２２と、蓄電池１１３に接続された第３の計測部１２３と、各種エネルギー源の情報収集を行う監視装置１２４と、ＧＰＳ（Global Positioning System：全地球測位システム）などの位置の測定を実行するための機能を用いて電力供給システム１００の設置位置を計測する位置情報計測部１２５と、ユーザの通信端末２００に情報を配信する通信装置１２６とを備える。通信装置１２６は、監視装置１２４が収集した情報と位置情報計測部１２５から受信した情報をユーザが持つ通信端末２００に配信するための無線機などからなる。 The control unit 120 includes a first measurement unit 121 connected to the fuel cell 111, a second measurement unit 122 connected to the solar cell 112, a third measurement unit 123 connected to the storage battery 113, and various types.

And a communication device 126 that distributes information to the communication terminal 200 of the user. The communication device 126 includes a wireless device for distributing the information collected by the monitoring device 124 and the information received from the position information measurement unit 125 to the communication terminal 200 owned by the user.
制御ユニット１２０は、電力供給システム１００が有する電源１１０から電力供給を受けるため、商用電源を必要としない。そのため、災害により商用電源が停電となっている場所においても機能を維持することができ、システムの設置場所や供給可能な電力量などの情報をユーザに配信することが可能である。 Since the control unit 120 receives power supply from the power supply 110 included in the power supply system 100, it does not require a commercial power supply. For this reason, the function can be maintained even in a place where the commercial power supply is interrupted due to a disaster, and information such as the installation location of the system and the amount of power that can be supplied can be distributed to the user.
電力供給システム１００の電源１１０は、負荷３００に接続することができ、電源１１０から負荷３００に電力を供給することができる。燃料電池１１１は、燃料貯蔵部１３０に貯蔵された燃料を消費することによって発電した電力を負荷３００に供給することができる。太陽電池１１２は、太陽光パネル（不図示）から得られた光エネルギーを電気エネルギーに変換することによって発電された電力を負荷３００に供給することができる。蓄電池１１３には充放電制御装置１２７が接続されており、蓄電池１１３の充放電を充放電制御装置１２７により制御することができる。蓄電池１１３の充放電を制御することにより、蓄電池１１３から負荷３００に電力を供給することができ、また、燃料電池１１１や太陽電池１１２等から供給された電力によって蓄電池１１３の充電をすることができる。 The power supply 110 of the power supply system 100 can be connected to the load 300 and can supply power to the load 300 from the power supply 110. The fuel cell 111 can supply electric power generated by consuming the fuel stored in the fuel storage unit 130 to the load 300. The solar cell 112 can supply the load 300 with electric power generated by converting light energy obtained from a solar panel (not shown) into electric energy. A charge / discharge control device 127 is connected to the storage battery 113, and charge / discharge of the storage battery 113 can be controlled by the charge / discharge control device 127. By controlling charging / discharging of the storage battery 113, power can be supplied from the storage battery 113 to the load 300, and the storage battery 113 can be charged by power supplied from the fuel cell 111, the solar battery 112, or the like. .
燃料電池１１３に燃料供給をする燃料貯蔵部１３０は、重量計１３１上に設置されている。重量計１３１は、燃料貯蔵部１３０の重量を計測し、計測した重量値を含む重量情報を第１の計測部１２１に転送することができる。 A fuel storage unit 130 that supplies fuel to the fuel cell 113 is installed on the weighing scale 131. The weigh scale 131 can measure the weight of the fuel storage unit 130 and transfer the weight information including the measured weight value to the first measurement unit 121.
第１の計測部１２１は、燃料電池１１１で発電された電力を計測し、また、重量計１３１から重量情報を受信して、燃料電池１１１の電力値及び重量情報を監視装置１２４に送信する。第２の計測部１２２は、太陽電池１１２で発電された電力を計測し、計測した太陽電池１１２の電力値を監視装置１２４に送信する。第３の計測部１２３は、蓄電池１１３から供給される電力及び残存容量を計測し、計測した蓄電池１１３の電力値及び残存容量値を監視装置１２４に送信する。 The first measuring unit 121 measures the power generated by the fuel cell 111, receives weight information from the weight scale 131, and transmits the power value and weight information of the fuel cell 111 to the monitoring device 124. The second measuring unit 122 measures the power generated by the solar battery 112 and transmits the measured power value of the solar battery 112 to the monitoring device 124. The third measuring unit 123 measures the power and remaining capacity supplied from the storage battery 113 and transmits the measured power value and remaining capacity value of the storage battery 113 to the monitoring device 124.
監視装置１２４は、第１の計測部１２１、第２の計測部１２２及び第３の計測部１２３からそれぞれ送信される電力値と、第１の計測部１２１を介して重量計１３１から送信される重量情報と、蓄電池１１１の残存容量値とを受信する。監視装置１２４は、重量情報、電力値及び残存容量値を収集・記録する機能を有する。また、監視装置１２４は、後述する２つの算出方法のいずれかを実行することにより燃料電池１１１の残存容量を導出する。 The monitoring device 124 transmits power values transmitted from the first measurement unit 121, the second measurement unit 122, and the third measurement unit 123, and is transmitted from the weighing scale 131 via the first measurement unit 121. The weight information and the remaining capacity value of the storage battery 111 are received. The monitoring device 124 has a function of collecting and recording weight information, power value, and remaining capacity value. Further, the monitoring device 124 derives the remaining capacity of the fuel cell 111 by executing one of two calculation methods described later.
１つ目の方法は、燃料貯蔵部１３０の重量に応じた発電可能な電力量を把握している場合に、燃料貯蔵部１３０の重量を燃料電池１１１の残存容量に換算する方法である。この方法は、重量あたりの発電量（Ｘ）として、予め監視装置１２４に燃料貯蔵部１３０の重量（Ｍ）を発電可能な電力量（Ｗｈ）に換算する式（Ｗｈ＝Ｘ×Ｍ）を入力しておき、計測した燃料貯蔵部１３０の重量（Ｍ）を発電可能な電力量（Ｗｈ）に換算することにより、燃料電池１１１の残存容量を算出することができる。 The first method is a method of converting the weight of the fuel storage unit 130 into the remaining capacity of the fuel cell 111 when the amount of power that can be generated according to the weight of the fuel storage unit 130 is known. In this method, an expression (Wh = X × M) for converting the weight (M) of the fuel storage unit 130 into the amount of electric power (Wh) that can be generated in advance is input to the monitoring device 124 as the amount of power generation (X) per weight. The remaining capacity of the fuel cell 111 can be calculated by converting the measured weight (M) of the fuel storage unit 130 into the amount of electric power (Wh) that can be generated.
２つ目の方法は、燃料電池１１１による発電電力と燃料貯蔵部１３０の重量とに基づいて、燃料貯蔵部１３０の重量を燃料電池１１１の残存容量に換算する方法である。図２に示すように、一定時間の間（ΔＴ）において燃料電池１１１が発電した電力量（ΔＷｈ）と燃料貯蔵部１３０の重量の変化（ΔＭ）とより、重量あたりの発電電力（ΔＷｈ／ΔＭ）を算出し、その算出した値を用いて、燃料貯蔵部１３０の重量（Ｍ）を発電可能な電力量（Ｗｈ）に換算（Ｗｈ＝ΔＷｈ／ΔＭ×Ｍ）することにより、燃料電池１１１の残存容量を算出することができる。 The second method is a method of converting the weight of the fuel storage unit 130 into the remaining capacity of the fuel cell 111 based on the power generated by the fuel cell 111 and the weight of the fuel storage unit 130. As shown in FIG. 2, the generated power per unit weight (ΔWh / ΔM) is calculated based on the amount of power (ΔWh) generated by the fuel cell 111 during a certain time (ΔT) and the change in the weight of the fuel storage unit 130 (ΔM). ) And using the calculated value, the weight (M) of the fuel storage unit 130 is converted into the amount of power (Wh) that can be generated (Wh = ΔWh / ΔM × M). The remaining capacity can be calculated.
監視装置１２４は、収集した電力値及び残存容量値に基づいて、燃料電池１１１が供給可能な電力量と、太陽電池１１２が単位時間当たり（例えば一時間当たり等）に供給可能な電力量と、蓄電池１１３が供給可能な電力量とを算出し、燃料電池１１１、太陽電池１１２及び蓄電池１１３が供給可能な電力量の和をとることにより、電力供給システムにおける供給可能な総電力量を算出する。監視装置１２４は、算出した供給可能な総電力量を負荷３００に対する電力供給値で割ることにより電力供給可能時間を算出する。監視装置１２４は、算出した供給可能な総電力量及び電力供給可能時間を通信装置１２６に送信する。 The monitoring device 124, based on the collected power value and remaining capacity value, the amount of power that the fuel cell 111 can supply, the amount of power that the solar cell 112 can supply per unit time (for example, per hour), The total amount of power that can be supplied in the power supply system is calculated by calculating the amount of power that can be supplied by the storage battery 113 and taking the sum of the amount of power that can be supplied by the fuel cell 111, the solar battery 112, and the storage battery 113. The monitoring device 124 calculates the power supply available time by dividing the calculated total amount of power that can be supplied by the power supply value for the load 300. The monitoring device 124 transmits the calculated total amount of power that can be supplied and the power supply available time to the communication device 126.
通信装置１２６は、監視装置１２４から供給可能な総電力量及び電力供給可能時間を受信し、位置情報計測部１２５から電力供給システム１００の設置位置を示す位置情報を受信する。通信装置１２６は、ユーザから要求があった場合に、ユーザから要求があった時点における供給可能な総電力量、電力供給可能時間及び位置情報をユーザの通信端末２００に送信する。ユーザの通信端末２００は、通信装置１２６から受信した各情報をディスプレイに表示することができ、それにより、ユーザはシステムの設置場所や供給可能な総電力量などを把握することができる。 The communication device 126 receives the total amount of power that can be supplied from the monitoring device 124 and the power supply available time, and receives position information indicating the installation position of the power supply system 100 from the position information measurement unit 125. When requested by the user, the communication device 126 transmits the total amount of power that can be supplied, the power supply available time, and the position information at the time when the request is received from the user to the communication terminal 200 of the user. The user communication terminal 200 can display each piece of information received from the communication device 126 on the display, whereby the user can grasp the installation location of the system, the total amount of power that can be supplied, and the like.
