It has been considered to charge an electric vehicle using commercial AC power from a house plug to supply an electric vehicle as a method of charging an electric vehicle. In addition, if a power failure occurs when the battery is charged by using the commercial AC power supply electric vehicle, the method of discharging the battery of the electric vehicle to supply the electric equipment in the house has been checked (for example, refer to Japanese Patent Application Publication No. No. 2006-158084). In the system disclosed in the aforementioned patent application 'When charging an electric vehicle', commercial alternating current power is supplied to the electric vehicle, and in the electric vehicle, alternating current power is converted into direct current power to charge the battery. Therefore, there is a problem in that conversion loss (c〇nversi〇n i〇ss) is generated when AC power is converted to DC power. Similarly, when the electric vehicle is discharged, the direct current power stored in the battery is converted into alternating current power and supplied to the house side.

distribution '5, the current embodiment is configured to switch the supply power of the local power supply source to less than the required electric power device 2 to the feed operation.胄 Bidirectional Power Feed In this embodiment, the required power is, for example, the total amount of power required for the operation of the load connected to the distribution circuit 10. The power can be set to the control device 3 via an external setting. For example, the required power is set to the control device 3 via a home shoper configured to perform a load operation. In this case, the home word processor is connected to a plurality of loads, and each of the plurality of loads is connected to the output of the power distribution circuit 1G. Each output is configured to provide information about the power required by the family word processor to load its own operations. The home server manages the information provided by the load and calculates the total amount of power required by the load. The home server transmits the total amount of power to the control device 3 as the required power. In the case where the electric vehicle 60 is charged, when the feed connector % of the charging slow line ca drawn from the bidirectional power feeding device 2 is connected to the connector 61 of the electric vehicle 60, the control portion 23 of the bidirectional power feeding device 2 makes The communication section 25 supplies a charging information transmission request to the electric vehicle 60 side. Here, the charging information transmission request is a request for transmitting charging information on the charging voltage and the charging current. When the communication circuit 64 of the electric vehicle 6 receives the charging information transmission request transmitted by the bidirectional power feeding device 2, the charging-discharging control circuit 65 causes the communication circuit 64 to supply information about the charging voltage and the charging current of the vehicle itself to the bidirectional power. Feed device 2. After the charging information is received via the communication portion 13 201127666 25 of the bidirectional power feeding device 2, the control portion 23 of the bidirectional power feeding device 2 and the DC power obtained by the control device 3 via the interface portion 24 based on the charging information received by the communication portion 25. The power feed capacity of the supply source determines whether it is possible to feed power with the DC switchboard i. Then, the control section knife 23 controls the output of the DC-DC converter 21 with the current value that can be supplied and the voltage value required on the electric vehicle side, thereby feeding the electric power to the electric vehicle 60 side. In the present embodiment, the photovoltaic device 5, the fuel cell 51, the storage battery 52, and the AC output from the commercial AC power supply source 〇〇 are converted to DC by the AC-to-DC converter 16. The DC power supply source is used as a DC power supply source for supplying DC power to the DC distribution board 1. In the presently preferred embodiment, control device 3 automatically performs a selection procedure that selects at least one DC power supply source for feeding power to electric vehicle 6〇 among a plurality of DC power supply sources. In this embodiment, the power fed by the AC to DC converter 16 can be set to the control device 3 via the setting/display device 4. For example, the upper limit value of the electric power fed from the alternating current to direct current converter 16 is set to the control device 3 via the setting/display device 4. For example, in the case of charging the battery 62 on the side of the electric vehicle 60, the prosthetic foot is fed by the parent stream to the DC converter 16 (configured to convert the AC input of the commercial AC power supply source 100 into DC). The use setting/displaying device 4 is set to zero, there is sunlight (in other words, 'power generation by the photovoltaic device 50 is performed), and there is electric power stored in the storage battery 52. Further, it is assumed that the electric vehicle 6 transmits a charging information of a charging voltage of 300 V DC and a charging current of 20 A (amperes) to the bidirectional power feeding device 2 in response to the charging information transmission request of 2011. This charging information is then further transmitted by the bidirectional power feeding device 2 to the control device 3. Here, the control device 3 is configured to capture the power feed capacity of each DC power supply. It is assumed that the power generation of the photovoltaic installation is 2,000 VA (volt-amperes), the power generation of the fuel cell 51 is 0 VA, the power supply capacity of the storage battery is 1 VA, and no other devices in the housing are consumed. Electricity. In this case, the control device 3 determines that the electric power that may be fed to the electric vehicle 60 is 3000 VA. The control device 3 controls the DC-to-DC converter 13 and the DC-to-DC converter 15' and uses the photovoltaic device 50 and the storage battery 52 as a power supply source with a charging voltage of 300 ν and a charging current of 1 〇Α. The state performs feeding power to the electric vehicle 6〇. Next, it is assumed that sunlight does not exist and other states are the same as described above. In this case, the control device 3 determines that the electric power that may be fed to the electric vehicle 60 is 1 〇〇〇 VA, which corresponds to the electric power feeding capacity of the storage battery 52. Subsequently, the control device 3 controls the DC-to-DC converter 15, and by using the storage battery 52 as a power supply source, performs feeding power to the electric vehicle 60 in a state where the charging voltage is 300 V and the charging current is 3.3a. Next, assume that the power fed by the AC-to-DC converter 16 (configured to convert the AC input of the commercial parent power supply 1 成 to DC) is set to 1000 VA, there is no sunlight, and there is storage stored. The power in the battery 52 and its power feed capacity is 1 〇〇〇 va. In the case of 15 201127666, the control device 3 determines that the electric power that may be fed to the electric vehicle 6 is 2000 VA. Subsequently, the control device 3 controls the DC-to-DC converter and the AC-to-DC converter 16, and by using an AC-to-DC converter 16 (configured to convert the AC input of the commercial AC power supply source 1 to DC) The battery 52 is stored as a power supply source, and feeding power to the electric vehicle 60 is performed in a state where the charging voltage is 300 V and the charging current is 66 a. Here, the control device 3 is configured to automatically select at least one optimized DC power supply source based on previously selected selection rules. However, any type of DC power supply source preferentially used to feed power may supply DC power from the DC distribution board 1 to the electric vehicle 60 side by using the setting/display device 4 setting to the control device as described above, and The battery 62 is charged via the charge-discharge circuit 63 of the electric vehicle 6〇. Here, if the power feeding from the DC power supply source is stopped, the control device 3 transmits the switching signal to the electric vehicle 60 via the bidirectional power feeding device 2. And then, the charge-discharge circuit 63 of the electric vehicle 6 turns the battery 62 to discharge the direct current power from the battery 62 to the DC switchboard 1 side. For example, 'assuming that the electric vehicle 6 is being charged at the night or the like', the power conversion of the commercial alternating current power supply source i is set to a minimum value by using the setting/display device 4, and the electric vehicle 60 is placed every other day. The mileage of the meter is set to 5 km. Since the photovoltaic installation 50 does not generate electricity at night, the current power feeding system uses the fuel cell 51 and the storage battery 52 as a power supply source while charging the electric vehicle 6〇16 201127666 and feeding the power to the load in the house. If the power feeding capacity combined with the fuel cell 51 and the storage battery 52 is lower than the power of the load in the house, the control device 3 outputs the switching signal to the bidirectional power feeding device 2' to drive the operation of the bidirectional power feeding device 2 from the electric device. The charging operation of charging the battery 62 of the vehicle 6 is changed to the discharge operation of discharging the battery (the feeding operation bidirectional power feeding skirt 2 transmits the switching signal to the electric vehicle 60. Subsequently, the charging-discharging control circuit 65 of the electric vehicle 60 Based on the switching signal received by the communication circuit 64, the charging/discharging circuit 63 is caused to perform a discharging operation (feeding operation), and thereby the DC power stored in the battery 62 is discharged to the two-way power feeding device 2 via the power line L3. In the feeding device 2, at this time, according to the switching signal input from the control device 3, the control portion 23 not only stops the operation of the DC-to-straight converter, but also causes the DC-to-DC converter Μ to apply the DC voltage from the electric vehicle 6G. (for example, 3GGV) is converted into the transmission voltage value of the power line of the Fukou house (for example, 35〇v), and the voltage is output to the straight machine. Therefore, the current power feeding system can supply the load in the house by using the lightning, electric && gate battery 62 of the electric vehicle 60. At the same time, the field uses 6 and / When the display device 4 sets the mileage calculated on the next day, the control device 3 transmits setting information about the driving mileage of the meter to the electric vehicle via the two-way power feeding device 2. The charging-discharging control of the electric vehicle 6〇& The # & a circuit 65 determines the necessary battery level required for the bucket V- and the driving range based on the setting information from the two-way power feeding device 2. After the input signal is switched to start the discharge of the battery 201127666, the charge_discharge control circuit 65 compares the remaining battery level of the battery α with the necessary battery level. If the remaining battery level of the battery 62 is lower than the necessary battery level, Then, the charge/discharge control circuit Μ automatically controls the charge-discharge circuit 63 to stop the discharge of the battery 62. Therefore, it is possible to ensure the battery level necessary for driving the mileage of the plan. The discharge control circuit 65 is configured to cause the communication circuit 64 to transmit a charge stop signal when the discharge of the battery pack is stopped to report the charge stop to the two-way power feed skirt 2. Upon receiving the charge stop signal, the two-way power feed device 2 enables The operation of the DC-to-DC converter 22 is stopped, and the interface portion 24 also sends a charging stop signal to the control device 3. When the control device 3 receives the charging stop signal, in order to compensate for the power difference caused by the electric vehicle 60 stopping the discharge, the control is performed. The device 3 operates the AC to DC converter 16, and the control device 3 causes the AC to DC converter 16 to convert AC power from the commercial AC power source to DC power ' and uses the DC power supply to store the battery 52 and load. In the current power feeding system, even when the battery 62 of the electric vehicle 6 is discharged to use the DC power distribution system of the discharge power supply house η, an overcurrent and/or a leakage occurs, and the load in the house 将 will be interrupted by the earth leakage. Protection (not shown) and/or protection of the DC breaker 12 arranged in the DC distribution panel 1. As explained above, in the power feeding system for an electric vehicle, when the battery 62 of the electric vehicle 60 is charged, the direct current power from the direct current distribution board 1 is supplied to the electric vehicle 60 via the bidirectional power feeding device 2. Therefore, it is not necessary to convert the alternating current into 18 201127666 DC in the side of the electric vehicle 60 so that the conversion loss caused by converting the alternating current into direct current is not generated. Further, when the battery 62 of the electric vehicle 60 is discharged to be fed by the electric vehicle force 60 side In the case of electric power, the bidirectional power feeding device 2 supplies the DC distribution board using the DC power stored in the battery 62 of the electric vehicle 60. Therefore, it is not necessary to convert DC power from an electric vehicle into AC power. The conversion loss caused by converting DC into a parent stream is not generated. Therefore, power can be used efficiently. In the power feeding system for an electric vehicle, the storage battery 52 can be charged using DC power discharged from the battery 62 of the electric vehicle 60. In this configuration, the DC power stored in the battery 62 of the electric vehicle 6〇 can be efficiently used by the load in the house. In the aforementioned power feeding system for an electric vehicle, the bidirectional power feeding device 2 includes two DC-to-DC converters 21, 22, and the DC-to-DC converter 21 is configured to perform direct (10) power supply to the house side at the time of charging. The electro-ink is converted to supply the electric vehicle 6 〇 side.
