When discharging the battery of the electric vehicle 60, the vehicle power converter 90 adjusts the voltage of the DC power discharged from the battery of the electric vehicle 60 using the bidirectional DC / DC converter and supplies the adjusted DC power to the power controller 70.

[0065] The power controller 70, the battery power converter 80, and the vehicle power converter 90 are linked together. Through the linkage of the power controller 70, the battery power converter 80, and the vehicle power converter 90, the power linkage device 100 controls the power supply to the main distribution board 16 and the sub-distribution board 28, the charging and discharging of the stationary battery 50, and the charging and discharging of the battery of the electric vehicle 60, as described in (1) to (4) below.

[0066] (1) When the AC output socket 17 of the first trailer house 10 is connected to the AC input socket 24 of the second trailer house 20, if the total power consumption of the loads in the trailer houses 10, 20 exceeds the total power generation of the natural energy power generation devices 13, 23, the power interconnection device 100 supplies the shortfall in power to the main distribution board 16 and the sub-distribution board 28 by discharging the stationary battery 50 and the battery of the electric vehicle 60.

[0067] (2) When the AC output socket 17 of the first trailer house 10 is connected to the AC input socket 24 of the second trailer house 20, if the total power consumption of the loads in the trailer houses 10, 20 is less than or equal to the total power generated by the natural energy power generation devices 13, 23, the power interconnection device 100 supplies surplus power from the natural energy power generation devices 13, 23 to charge the stationary battery 50 and the battery of the electric vehicle 60.

[0068] (3) When the AC output socket 17 of the first trailer house 10 is disconnected from the AC input socket 24 of the second trailer house 20, if the total power consumption of the loads in the first trailer house 10 exceeds the power generated by the natural energy power generation device 13, the power interconnection device 100 supplies the shortfall in power to the main distribution board 16 by discharging the stationary battery 50 and the battery of the electric vehicle 60.

[0069] (4) When the AC output socket 17 of the first trailer house 10 is disconnected from the AC input socket 24 of the second trailer house 20, if the total power consumption of the loads in the first trailer house 10 is less than or equal to the power generated by the natural energy power generation device 13, the power interconnection device 100 supplies surplus power from the natural energy power generation device 13 to charge the stationary battery 50 and the battery of the electric vehicle 60.

[0070] Note that, when the electric vehicle 60 is disconnected from the vehicle power converter 90, the electric power collaboration device 100 does not charge or discharge the battery of the electric vehicle 60 in the above (1) to (4).

[0071] The commercial power supply may be connected to the power switch 15 via a junction box. When the commercial power supply is connected to the power switch 15, the power switch 15 can switch the power supply source between being set to the commercial power supply only or to being set to both the commercial power supply and the power controller 70. When the source of power supply to the trailer houses 10, 20 is set to commercial power only, AC power supplied from the commercial power source to the main distribution board 16 is distributed by the main distribution board 16 to the loads in the first trailer house 10, AC power supplied from the commercial power source to the sub-distribution board 28 is distributed by the sub-distribution board 28 to the loads in the second trailer house 20, and power generated by the natural energy power generation devices 13, 23 is charged by the power interconnection device 100 to the battery of the electric vehicle 60 and the stationary battery 50. Surplus power generated by the natural energy power generation devices 13, 23 may be reverse-flowed to the commercial power source by the power interconnection device 100. When the sources of power supply to the trailer houses 10, 20 are set to both the commercial power source and the power controller 70, the power linkage device 100 controls the power supply to the main distribution board 16 and the sub-distribution board 28, the charging and discharging of the stationary battery 50, and the charging and discharging of the battery of the electric vehicle 60, through coordination between the power controller 70, the battery power converter 80, and the vehicle power converter 90, and also controls the forward flow and reverse flow to the commercial power source based on the total power consumption of the loads in the trailer houses 10, 20, the power generated by the natural energy power generation devices 13, 23, the charging rate of the stationary battery 50, or the charging rate of the battery of the electric vehicle 60.

[0072] <6. Summary> (1) As shown in FIG. 1, the residential facility 1 includes two trailer homes 10 and 20, providing a spacious living space where residents can live comfortably.

[0073] (2) As shown in FIG. 1, the trailer houses 10 and 20 are each equipped with a natural energy power generation device 13 and 23, the trailer houses 10 and 20 are each equipped with a distribution board 16 and 28, and the power interconnection device 100 electrically interconnects the natural energy power generation devices 13 and 23 with the distribution boards 16 and 28. Therefore, the electricity required for living in the trailer houses 10 and 20 is supplied by the natural energy power generation devices 13 and 23 through the distribution boards 16 and 28.

[0074] (3) As shown in Fig. 1, the power interconnection device 100 interconnects the stationary battery 50 and the battery of the electric vehicle 60 in addition to the natural energy power generation devices 13, 23 and the distribution boards 16, 28, so that surplus power generated by the natural energy power generation devices 13, 23 is charged into the stationary battery 50 and the battery of the electric vehicle 60. If the power generated by the natural energy power generation devices 13, 23 is insufficient to provide the power needed for living in the trailer houses 10, 20, the stationary battery 50 and the battery of the electric vehicle 60 make up for the shortfall. These factors contribute to the effective use of surplus power.

[0075] (4) As shown in FIG. 2, when the second trailer house 20 is disconnected from the first trailer house 10, the power interconnection device 100 electrically interconnects the first natural energy power generation plant 13 with the stationary battery 50, the battery of the electric vehicle 60, and the main distribution board 16, so that the first trailer house 10 can use the power generated by the first natural energy power generation plant 13.

[0076] (5) As shown in FIG. 2, even if the second trailer house 20 is separated from the first trailer house 10, surplus electricity can be effectively utilized in the first trailer house 10 by charging and discharging the stationary battery 50 and the battery of the electric vehicle 60. Therefore, even outside the site 2, a life with electricity can be lived in the second trailer house 20.

[0077] (5) Because the stationary battery 50 is installed on the site 2, the trailer houses 10, 20 do not need to have batteries. This allows for a larger living space inside the trailer houses 10, 20, making it possible to live comfortably in the trailer houses 10, 20. Similarly, because surplus power is charged and discharged using the battery of the electric vehicle 60 parked on the site 2, the living space inside the trailer houses 10, 20 can be larger. Similarly, because the power interconnection device 100, the water reclamation device 40, and the water heater 45 are installed on the site 2, the living space inside the trailer houses 10, 20 can be larger.

[0078] (6) The trailer homes 10 and 20 parked on site 2 can be removed from site 2 by towing. When the first trailer home 10 returns to site 2, the first trailer home 10 can continue to live with electricity. Even when both the first trailer home 10 and the second trailer home 20 return to site 2, the trailer homes 10 and 20 can continue to live with electricity.

[0079] (7) As shown in Figure 1, the water recycling system 40 installed on the site 2 recycles wastewater discharged from the plumbing equipment 30 of the second trailer house 20 into clean water or recycled water, and supplies the clean water or recycled water to the plumbing equipment 30. This allows people in the trailer houses 10 and 20 to live a life with access to water.

[0080] (8) As shown in Figure 1, the water reclamation device 40 supplies clean water or grey water to the water heater 45, which heats the clean water or grey water and supplies it to the plumbing equipment 30. This allows people in the trailer houses 10 and 20 to live with hot water.

[0081] (9) Wood is used as a material for the houses 12 and 22. The energy used from the production to the disposal and disposal of wood is less than the energy used from the production to the disposal and disposal of metal or concrete materials. Therefore, the trailer houses 10 and 20 contribute to the realization of a decarbonized society by promoting carbon neutrality, which reduces carbon dioxide emissions to virtually zero, and to the achievement of the Sustainable Development Goals (SDGs).
