  Hereinafter, the present invention will be described through embodiments of the invention. However, the following embodiments do not limit the invention according to the scope of claims, and all combinations of features described in the embodiments are included. It is not necessarily essential for the solution section of the invention.

  FIG. 1 is a diagram illustrating an example of a configuration of a power system 100 according to an embodiment of the present invention. The power system 100 is a system for supplying power to, for example, an electric device 10 used in each home, and includes a plurality of electric devices 10, a fuel cell 50, wiring 20, and a power distribution unit 40.

  The plurality of electrical devices 10 are connected to the fuel cell 50 via the wiring 20 and the power distribution unit 40 and are driven by the power generated by the fuel cell 50. As shown in FIG. 1, at least one of the plurality of electrical devices 10 includes a load 12, a suppression unit 14, a power switch 16, a memory 18, an increase notification unit 22, and a permission reception unit 24. The other electrical device 10 may have the same configuration as the electrical device 10 or may have a configuration including the load 12 and the power switch 16.

  The load 12 is a power load that consumes power. The power switch 16 is a switch for switching whether or not the electric power generated by the fuel cell 50 is input to the load 12 of the electric device 10. When the power switch 16 is operated by the user and is turned on, the power is turned on to activate the electric device 10.

  The suppression means 14 suppresses an increase in power input to the electrical device 10 when the power switch 16 is turned on according to the power generation status of the fuel cell 50. For example, the fuel cell 50 increases the power generation amount when the power switch 16 of the electric device 10 is turned on, and the suppression unit 14 inputs the increase in the power generation amount of the fuel cell 50 to the electric device 10. When the power becomes substantially equal to the power, power is supplied to the load 12 of the electrical device 10. In addition, the suppression unit 14 may control the increase rate of the power input to the electric device 10 according to the increase rate of the power generation amount of the fuel cell 50. That is, the suppression unit 14 may supply the load 12 of the electrical device 10 with power that is approximately equal to the increase in the power generation of the fuel cell 50.

  The increase notification unit 22 notifies the fuel cell 50 of an increase notification indicating that the power consumption increases when the power switch 16 is turned on. For example, the increase notification unit 22 may notify the fuel cell 50 of the magnitude of the starting power (rush power) necessary for starting the electric device 10. In this case, the magnitude of the startup power of the electrical device 10 is stored in advance in the memory 18, and the increase notification unit 22 determines the magnitude of the startup power from the memory 18 when the power switch 16 is turned on. Read out and notify the fuel cell 50.

  The permission receiving unit 24 receives a power consumption increase permission notification from the fuel cell 50 when the fuel cell 50 permits the power consumption to be increased in response to the increase notification from the increase notification unit 22. The suppression unit 14 supplies power to the load 12 of the electrical device 10 when the permission receiving unit 24 receives the permission notification.

  In this example, the suppression unit 14 suppresses the power supplied to the load 12 when the power switch 16 is turned on. However, the load 12 similarly applies when the power consumption fluctuates after the load 12 is activated. The power supplied to the battery may be suppressed. In this case, the increase notification unit 22 notifies the fuel cell 50 of an increase notification indicating that the power consumption increases when further increase in power consumption is required after the electric device 10 is started. When the permission receiving unit 24 receives a notification of increase in power consumption in response to the increase notification from the increase notification unit 22, the power to be supplied to the electrical device 10 is increased. The increase notification unit 22 preferably notifies the increase amount of the power consumption when the power consumption of the electric device 10 needs to be increased.

  In addition, the wiring 20 connects the power distribution unit 40 to the plurality of electric devices 10 and the fuel cell 50, and the power distribution unit 40 receives the power generated by the fuel cell 50 and supplies it to each electric device 10.

  The fuel cell 50 includes a power generation unit 52, an increase reception unit 54, a permission notification unit 58, and a control unit 56. The power generation unit 52 includes, for example, a reformer that receives raw fuel such as city gas, LPG, gasoline, and methanol from the outside and generates hydrogen gas, and a cell stack that generates power using the hydrogen gas as fuel.

  The increase receiving unit 54 receives the increase notification received from the increase notification unit 22 of each electrical device 10. The control unit 56 increases the power generation amount in the power generation unit 52 when the increase reception unit 54 receives the increase notification. At this time, the control unit 56 increases the power generation amount in the power generation unit 52 according to the increase amount of power consumption notified from the increase notification unit 22.

  The permission notification unit 58 issues a permission notification for permitting an increase in power consumption of the electrical device 10 when the increase in power generation amount in the power generation unit 52 becomes substantially equal to the increase in power consumption of the electrical device 10. This is notified to the permission receiving unit 24 of the device 10.

  By such an operation, for example, when at least one of the electrical devices 10 is being driven, even if the total power consumption varies greatly, such as when another electrical device 10 is newly activated, the drive is performed. The necessary electric power can be supplied to the other electric device 10 without changing the electric power supplied to the electric device 10. Further, according to the power system 100, since the power generation amount of the fuel cell 50 can follow the fluctuation of the power consumption of the electric device 10, the power consumption of the electric device 10 is not changed, so that the secondary that has been conventionally used is used. The battery can be omitted.

  FIG. 2 is a diagram illustrating an example of the operation of the power system 100. FIG. 2A is a diagram illustrating an example of the operation of the electric device 10, and FIG. 2B is a diagram illustrating an example of the operation of the fuel cell 50. In this example, an operation of the power system 100 when the electric device 10 is started will be described.

As shown in FIG. 2 (a), for example, when the power switch 16 at time T ₁ is turned on, the power switch 16, electrical device 10 attempts to supply a rated power greater starting power to the load 12, electrical equipment The power consumption at 10 increases by ΔW. However, the power generation amount of the fuel cell 50 does not increase instantaneously as shown in FIG. For this reason, the increase notification unit 22 notifies the fuel cell 50 that the power increases, and the suppression unit 14 supplies power to the load 12 until the increase in the power generation amount of the fuel cell 50 reaches the increase in power consumption. Do not throw in. When the increase in the amount of power generated by the fuel cell 50 becomes ΔW at time T ₂ , the suppression unit 14 supplies power to the load 12 in response to a notification from the fuel cell 50.

  The increase notification unit 22 and permission reception unit 24 of the electric device 10 and the increase reception unit 54 and permission notification unit 58 of the fuel cell 50 may communicate with each other by wireless communication or may communicate by wired communication. When performing wired communication, it is preferable to communicate with each other using a wiring for supplying power from the fuel cell 50 to the electrical device 10. In this case, the increase notification unit 22 and the permission reception unit 24 may be provided in a power plug to be connected to an outlet to which power is supplied from the fuel cell 50.

  FIG. 3 is a diagram illustrating an example of the configuration of the power plug 28 included in the electrical device 10. In this example, the fuel cell 50 supplies electric power to the electric device 10 through an outlet 94 provided in the house, and the electric device 10 is electrically connected to the outlet 94 and uses the electric power generated by the fuel cell 50. Further, a power plug 28 for supplying the electric device 10 is further provided.

  The outlet 94 is provided on the inner wall of a house, for example, and supplies electric power from the fuel cell 50 to the connected electrical device 10. The power plug 28 is provided between the power switch 16 and the outlet 94, and receives power generated by the fuel cell 50 by being electrically connected to the outlet 94.

  In this example, the increase notification unit 22, the memory 18, and the permission receiving unit 24 described with reference to FIG. 1 are provided in the power plug 28. Further, the power plug 28 further includes an insertion portion 26 and a wiring 20-1. The plug 26 is electrically connected by being plugged into the outlet 94 and receives power from the outlet 94. The wiring 20-1 supplies the power received by the plug-in unit 26 to the load 12 via the power switch 16.

  In this example, the increase notification unit 22 notifies the fuel cell 50 of the magnitude of the starting power via the outlet 94. For example, it is notified that power consumption is increased by superimposing an AC signal on the wiring 20 for receiving power from the fuel cell 50. The increase receiving unit 54 of the fuel cell 50 receives the increase notification by detecting an AC signal superimposed on the wiring 20 for supplying electric power to the electric device 10.

  In addition, the permission notification unit 58 of the fuel cell 50 notifies the permission notification by superimposing the AC signal on the wiring 20, and the permission receiving unit 24 detects the permission notification by detecting the AC signal superimposed on the wiring 20. receive.

  Since the fuel cell 50 generates DC power, when the electric device 10 operates with AC power, the DC power needs to be converted into AC power and supplied to the load 12. The electric device 10 may further include a DC-AC converter 32 that converts DC power into AC power. The DC-AC converter 32 is provided, for example, on the wiring 20 between the plug-in unit 26 and the power switch 16. In this case, it is preferable that the permission receiving unit 24 and the increase notification unit 22 are electrically connected to a region of the wiring 20 that transmits DC power. That is, the permission receiving unit 24 and the increase notification unit 22 are preferably electrically connected to the wiring 20 between the DC-AC converter 32 and the plug-in unit 26. Thereby, since the AC signal as the increase notification and the permission notification can be superimposed on the transmission path of the DC power, the AC signal can be easily detected.

  Further, when the fuel cell 50 includes the DC-AC converter 32 and AC power is supplied to the electric device 10, the increase notification unit 22 and the permission notification unit 58 are connected to the AC power supplied to the electric device 10. It is preferable to superimpose AC signals in different frequency bands on the wiring 20.

  In addition, it is preferable that driving power is supplied from the fuel cell 50 to the permission receiving unit 24 and the increase notification unit 22 regardless of whether the power switch is turned on. In the configuration described with reference to FIG. 1, it is preferable that standby power supplied from the fuel cell 50 is given to the permission receiving unit 24 and the increase notification unit 22.

  FIG. 4 is a diagram illustrating another example of the configuration of the power system 100. In this example, the electric device 10 includes a load 12, a suppression unit 14, a power switch 16, a monitoring unit 34, a comparison unit 36, and an increase notification unit 22. Further, the fuel cell 50 shakes the power generation unit 52, the increase reception unit 54, and the control unit 56. 4, components having the same reference numerals as those in FIG. 1 may have the same configurations and functions as the components described in relation to FIG.

  In the electric device 10, the load 12, the power switch 16, the power generation unit 52, the control unit 56, and the increase reception unit 54 are the same as the load 12, the suppression unit 14, and the power switch 16 described with reference to FIG. Therefore, the description is omitted. The monitoring unit 34 monitors the voltage of power supplied to the load 12 of the electrical device 10. The comparison unit 36 compares the voltage monitored by the monitoring unit 34 with a predetermined reference value. When AC power is supplied to the electrical device 10, the monitoring unit 34 may measure the peak voltage of the AC power, and the comparison unit 36 may compare the peak voltage with the reference value.

  Then, when the power consumption increases in the load 12, the suppression unit 14 increases the power supplied to the load 12 of the electrical device 10 if the voltage monitored by the monitoring unit 34 is equal to or higher than the reference value. When the voltage monitored by the monitoring unit 34 is smaller than the reference value, an increase in power supplied to the load 12 is suppressed. When the voltage monitored by the monitoring unit 34 is smaller than the reference value, the increase notification unit 22 transmits an increase notification to the fuel cell 50 to increase the power generation amount of the fuel cell 50. And when the monitoring voltage in the monitoring part 34 becomes more than the said reference value by the power generation amount of the fuel cell 50 increasing, the suppression means 14 increases the electric power supplied to the load 12. FIG. Also by such an operation, when the power consumption of any one of the electrical devices 10 increases, it is possible to control without changing the power supplied to the other electrical devices 10.
