Power generation efficiency information representing η is included. In addition, an air supply amount control program 48 for the CPU 22A to perform an air supply amount control process to be described later is also installed in the storage unit 22C.

  The control ECU 22 is an example of a control unit according to the present invention, the air supply amount control program 48 is an example of a control program for an air supply device according to the present invention, and the storage unit 22C is a storage unit according to claim 2. It is an example.

  Next, the operation of this embodiment will be described. In the present embodiment, in an emergency such as a power failure when the power supply from the grid power supply 18 is cut off, the user (for example, a resident of the house 12) does not receive the hydrogen fuel cell vehicle 50 in the garage 14. 14, after the hydrogen fuel cell vehicle 50 is received, the connector 44 of the power transmission cable 42 is connected to the connection portion 58 of the hydrogen fuel cell vehicle 50, and power generation by the power generation unit 54 of the hydrogen fuel cell vehicle 50 is started. An operation of supplying the electric power generated by the power generation unit 54 to the outside through the connection unit 58 is performed.

  With the above operation, the electric power generated by the power generation by the power generation unit 54 of the hydrogen fuel cell vehicle 50 is supplied to the switch 16 via the connection unit 58, the connector 44, the power transmission cable 42, and the power supply / reception device 40. The switcher 16 notifies the control ECU 22 when the supply of power from the hydrogen fuel cell vehicle 50 is started and when the supply of power from the hydrogen fuel cell vehicle 50 is completed. When the control ECU 22 is notified from the switcher 16 that the supply of power from the hydrogen fuel cell vehicle 50 has been started, the CPU 22A executes the air supply amount control program 48, whereby the air supply amount shown in FIG. Perform control processing.

  In step 100 of the air supply amount control process, the control ECU 22 switches the switch 16 so that the power generated by the power generation by the power generation unit 54 of the hydrogen fuel cell vehicle 50 is supplied to the distribution board 20 (the house 12 side). . As a result, various electric / electronic devices installed in the house 12 become operable by the electric power supplied from the hydrogen fuel cell vehicle 50 via the switch 16 and the distribution board 20.

In the next step 102, the control ECU 22 reads vehicle information 46 (information including the hydrogen amount H and the power generation efficiency η) of the hydrogen fuel cell vehicle 50 from the storage unit 22C. In step 104, the control ECU 22 causes the CT sensor 32 to measure the current power consumption E on the house 12 side. In step 106, the control ECU 22 determines the current power consumption E on the house 12 side measured in step 104 and the vehicle information 46 (hydrogen amount H) of the hydrogen fuel cell vehicle 50 read from the storage unit 22C in step 102. And the power generation efficiency η), the oxygen consumption C _O per hour accompanying the power generation by the power generation unit 54 of the hydrogen fuel cell vehicle 50 is calculated.

The oxygen consumption amount C _O per hour can be obtained by the following equation (1).
C _O = C · E / G (1)
Note that G is a total power generation amount when the power generation unit 54 of the hydrogen fuel cell vehicle 50 generates power with a power generation efficiency η using hydrogen with a hydrogen amount H, and the total power generation amount G is the hydrogen amount H. It is uniquely obtained from the power generation efficiency η (G = f (H, η)). C is the total oxygen consumption when the power generation unit 54 of the hydrogen fuel cell vehicle 50 generates power using hydrogen with a hydrogen amount H, and the total oxygen consumption C is uniquely determined from the hydrogen amount H ( C = f (H)).

As an example, when the hydrogen amount H = 5 kg and the power generation efficiency η = 0.4, the total power generation amount G = 67 kwh, the total oxygen consumption C = 28 m ³ , and the current power consumption E = 1.0 kwh on the house 12 side. If there would oxygen consumption per hour C _O = 0.42m ³ / h.

In the next step 108, the control ECU 22 calculates the air supply amount V per hour by the air supply fan 34 from the oxygen consumption amount C _O calculated in step 106. The air supply amount V per hour is obtained by the following equation (2).
V = C _O /0.2095 (2)
However, 0.2095 is the oxygen concentration in the atmosphere (= 20.95%). As an example, when the oxygen consumption per hour C _O = 0.42m ³ / h, becomes Kyukiryou V = 1.99m ³ / h.

  In the next step 110, the control ECU 22 controls the rotational speed of the impeller 34 </ b> A of the air supply fan 34 based on the air supply amount V. The air supply fan 34 according to this embodiment is configured to supply outside air into the garage 14 by the rotation of the impeller, and in this configuration, the amount of air supplied by the air supply fan 34 is proportional to the rotational speed of the impeller 34A. Therefore, the above control can be realized by a simple control of rotating the impeller 34A at a rotation speed proportional to the air supply amount V. By repeating the above-described Step 104 to Step 110, an amount of oxygen substantially equal to the amount of oxygen consumed in the garage 14 due to the power generation of the power generation unit 54 of the hydrogen fuel cell vehicle 50 is supplied by the air supply fan 34 to the garage 14. The air supply amount V into the garage 14 by the air supply fan 34 is controlled so as to be supplied inside.

  In the next step 112, the control ECU 22 causes the oxygen concentration sensor 38 to measure the oxygen concentration in the garage 14. In step 114, the control ECU 22 determines whether the oxygen concentration in the garage 14 measured by the oxygen concentration sensor 38 is 20.5% or more. When the determination in step 112 is affirmed, the process proceeds to step 116, and the control ECU 22 determines whether the supply of power from the hydrogen fuel cell vehicle 50 has been notified from the switch 16 or not. It is determined whether or not the power supply from the fuel cell vehicle 50 to the house 12 has been completed.

  If the determination in step 116 is negative, the process returns to step 104, and steps 104 to 116 are repeated. For example, when the power supply from the hydrogen fuel cell vehicle 50 to the house 12 side is terminated due to consumption of all the hydrogen stored in the hydrogen storage unit 52 of the hydrogen fuel cell vehicle 50, the determination in step 116 is made. The affirmation is affirmed and the air supply amount control process is terminated.

  On the other hand, in steps 104 to 110 described above, an oxygen amount substantially equal to the amount of oxygen consumed in the garage 14 due to the power generation of the power generation unit 54 of the hydrogen fuel cell vehicle 50 is introduced into the garage 14 by the air supply fan 34. Since it is supplied, the oxygen concentration in the garage 14 should be maintained at 20.95% (an example of the predetermined value in the present invention) which is the oxygen concentration in the atmosphere in principle. However, in reality, the oxygen concentration in the garage 14 may fluctuate due to, for example, an error in the supply amount control, and may decrease to a threshold value of less than 20.5%.

  If the oxygen concentration in the garage 14 has decreased to less than 20.5%, the determination in step 114 is denied and the process proceeds to step 118. In step 118, the control ECU 22 generates power from the power generation unit 54 of the hydrogen fuel cell vehicle 50. Is executed, and the air supply amount control process is terminated. As a process for stopping power generation, for example, a process for displaying a message for requesting stoppage of power generation by the hydrogen fuel cell vehicle 50 or a process for outputting a voice requesting stoppage of power generation by the hydrogen fuel cell vehicle 50 Etc. Thereby, an operation for stopping the power generation by the hydrogen fuel cell vehicle 50 is performed by the user.

  The process for stopping the power generation is not limited to the above, and the configuration of the residential power supply control device 10 is slightly complicated, but a function of communicating with the hydrogen fuel cell vehicle 50 is provided, and the hydrogen fuel cell You may make it stop the electric power generation by the hydrogen fuel cell vehicle 50 by transmitting the signal which instruct | indicates the stop of an electric power generation with respect to the motor vehicle 50. FIG.

[Second Embodiment]
Next, a second embodiment of the present invention will be described. In addition, the same code | symbol is attached | subjected to the part same as 1st Embodiment, and description is abbreviate | omitted.

  FIG. 3 shows a house 12 in which the house power supply control device 70 according to the second embodiment is installed. The residential power supply control device 70 differs from the residential power supply control device 10 described in the first embodiment only in that the oxygen concentration sensor 38 is omitted.

  Next, with reference to FIG. 4, the air supply amount control process according to the second embodiment will be described only for parts different from the air supply amount control process described in the first embodiment.

In the air supply amount control process according to the second embodiment, after calculating the air supply amount V per hour by the air supply fan 34 in step 108, in the next step 130, the control ECU 22 starts with step 106. The oxygen consumption C _O per hour calculated repeatedly is integrated over the period from the start of power generation in the hydrogen fuel cell vehicle 50 to the current time t. This integration result corresponds to the result of integrating the oxygen consumption amount C _O per hour over the period, and represents the total consumption amount of oxygen in the garage 14 during the period. This is referred to as oxygen consumption Ct. The oxygen consumption amount Ct until time t is an example of the transition of the oxygen consumption amount according to claim 5.

Further, the control ECU 22 converts the air supply amount V per hour repeatedly calculated in step 108 into an oxygen supply amount S ₀ per hour according to the following equation (3), and converts the converted oxygen per hour: The supply amount S ₀ is integrated over a period from the start of power generation in the hydrogen fuel cell vehicle 50 to the current time t.
S ₀ = 0.2095 · V (3)
This integration result corresponds to the result of integrating the oxygen supply amount S ₀ per hour over the period, and represents the total supply amount of oxygen to the garage 14 during the period. This is referred to as the total oxygen supply amount St. The total oxygen supply amount St is an example of a transition of the oxygen supply amount according to claim 5.

Based on the oxygen consumption Ct until time t, the total oxygen supply amount St until time t, and the volume M of the garage 14 obtained by the above calculation, the control ECU 22 performs garage 14 according to the following equation (4). The current oxygen concentration Dt is estimated and calculated.
Dt = ((0.2095 · M) + St−Ct) / M (4)
By the above calculation, the current oxygen concentration Dt in the garage 14 can be obtained without using the oxygen concentration sensor 38 described in the first embodiment.

  In addition, the process of step 130 is an example of the process by the estimation part in this invention, and control ECU22 is an example of the estimation part in this invention in this 2nd Embodiment.

In the next step 132, the control ECU 22 determines whether the current oxygen concentration Dt estimated in step 132 and the preset target oxygen concentration D _REF (for example, D _REF = 0.2095) are different in the previous step 108. by correcting the calculated air charge amount V, calculates the air charge V _X per hour by the air supply fan 34 (see the following equation (5)).
V _X = V + ΔV = V + α (Dt−D ₀ ) (5)
However, ΔV is a correction value for the air supply amount V, and α is a proportionality constant.

FIG. 5 shows an example of the relationship between the deviation between the current oxygen concentration Dt and the target oxygen concentration D _REF and the supply amount correction value ΔV. As shown in FIG. 5, the supply amount correction value ΔV increases as the deviation between the current oxygen concentration Dt and the target oxygen concentration D _REF increases (the supply amount V _X increases). Can be determined. The supply amount correction value ΔV is not limited to linear change as shown in FIG. 5 with respect to the change in deviation between the current oxygen concentration Dt and the target oxygen concentration D _REF , but the deviation As long as the value increases as the value increases, it may be a non-linear change.

In the next step 134, the control ECU 22 controls the rotational speed of the impeller 34 </ b> A of the air supply fan 34 based on the air supply amount V _X per hour by the air supply fan 34 calculated in step 132. By repeating the above-described processing, the air supply amount V _X into the garage 14 by the air supply fan 34 is controlled so that the current oxygen concentration Dt in the garage 14 matches the target oxygen concentration D _REF . Further, when the current oxygen concentration Dt is different from the target oxygen concentration D _REF for some reason, the supply air is determined so that the value increases as the deviation between the current oxygen concentration Dt and the target oxygen concentration D _REF increases. Since the air supply amount V is corrected by the amount correction value ΔV, the air supply amount V _X into the garage 14 by the air supply fan 34 is controlled so that the current oxygen concentration Dt quickly matches the target oxygen concentration D _REF. Will be.

  In the first embodiment and the second embodiment, the air supply amount V into the garage 14 by the air supply fan 34 so that the oxygen concentration in the garage 14 matches the oxygen concentration in the atmosphere (= 20.95%). However, in the present invention, the target oxygen concentration in the garage 14 (predetermined value in the present invention) is not limited to the above numerical value, and the oxygen concentration in the atmosphere (= 20.95%) and the Building Standard Law Any value between defined values (= 20.5%) is applicable. Also, as the threshold value in the present invention, a value other than the oxygen concentration 20.5% defined by the Building Standard Law may be applied.

  Further, in the first embodiment and the second embodiment, the supply fan 34 causes the garage 14 to supply an amount of oxygen substantially equal to the amount of oxygen consumed in the garage 14 as the power generation unit 54 of the hydrogen fuel cell vehicle 50 generates power. Although the aspect which controls the air supply amount V in the garage 14 by the air supply fan 34 so that it may be supplied in the inside was demonstrated, it is not limited to this, From the amount of oxygen consumed in the garage 14 The air supply amount V into the garage 14 by the air supply fan 34 may be controlled so that a larger amount of oxygen is supplied into the garage 14 by the air supply fan 34.
