  The small-scale power source 27 is a relatively small-scale power generation facility attached to the facility where the power source 22 is installed. The small-scale power source 27 is provided by a private power generation device, a solar power generation device, a fuel cell, a wind power generation device, or the like installed in a house or business office. The power supplied from the small-scale power supply 27 may have an advantage in some viewpoints compared to the power supplied from the AC power supply 24. For example, when the small-scale power supply 27 is a solar power generation device, electric power may be supplied cheaper than the AC power supply 24 in the daytime. Further, when the small-scale power supply 27 is a solar power generation device, it may be possible to supply electric power with a smaller environmental load than the AC power supply 24. The small-scale power source 27 that provides such advantages is also called another power source different from the AC power source 24.

  The electric vehicle 32 includes a battery 34, a charge / discharge circuit 35, and a control device 38. The control circuit 38 is compatible with both the first control method and the second control method. Therefore, the electric vehicle 32 can be connected to both the power source 22 and the power source 21 described above, and can exchange power. As a result, the electric vehicle 32 can execute a charging process based on the second control method with the power source 22.

Under the second control method, the control devices 26 and 38 are ready to charge the battery 34 in response to the connection operation of the connector 25 and the inlet 37 as in the first control method. Further, under the second control method, the control devices 26 and 38 automatically stop charging in response to the completion of charging of the battery 34 as in the first control method.

  Further, the control devices 26 and 38 provide an additional function in addition to the basic function for charging in response to the connection operation of the connection device and the completion of charging of the battery 34.

The charging process by the second control method can be referred to as a more advanced charging process in comparison with the charging process by the first control method that only charges the electric vehicle 31. In addition to the basic function for charging the battery 34, the charging process provided in the second control method further includes an additional function. The additional function is also referred to as a high function charge process or high function charge control. The charging process provided in the second control method can also be referred to as energy management charging control that comprehensively manages energy in the electric vehicle 32 and the power source 22.

  In the charging process of the second control method, for example, adjustment of the charging start time, adjustment of the charging speed, or power source control in the power source 22 is provided. More specifically, a charging process that suppresses the power cost for charging can be included. For example, in order to charge the electric vehicle 32, a low-price charging process of a power charge table selection type such as searching for and using a lower-price power source and / or a lower-priced time zone may be provided. . For example, the control device 26 adjusts the power supply time zone so that the electric power obtained by the small-scale power source 27 is used or the electric vehicle 32 is charged in the time zone in which cheap power is obtained from the AC power source 24.

  The charging process of the second control method can include power control for adjusting power consumption in a facility where the power supply 22 is installed. For example, in order to suppress the peak of power consumption in the wide area power network, peak cut charging control for limiting charging to the electric vehicle 32 may be provided.

  The charging process of the second control method can include a process for selecting the power supplied to the connector 25. For example, the control device 26 selectively supplies power to the connector 25 from a plurality of power supply devices including the AC power supply 24 and the small-scale power supply 27.

  FIG. 3 shows the charging system 13 in the case where the electric vehicle 32 adapted to the second control method is charged from the power source 21 and the adapter 41 adapted only to the first control method.

The communication line COM may be configured via connection devices 44, 33, and 37 for charging. Further, the communication line COM may be configured by a wire provided separately without going through the connection devices 44, 33, and 37.

  In the charging system 15, a power source 22 that conforms to the second control method is used. In the charging system 15, an electric vehicle 31 adapted only to the first control method is used. The electric vehicle 31 has a communication line LAN for data communication. The communication line LAN is an internal network laid in the electric vehicle 31. The communication line LAN is a local area network that connects a plurality of control devices and electric circuits so that data communication is possible. The communication line LAN connects the charge / discharge circuit 35, the control device 36, and the communication device 39 so that data communication is possible. The charge / discharge circuit 35 can be connected as a controllable element from the control device 36 and / or the communication device 39.

  The electric vehicle 31 includes an in-vehicle communication device 39. The in-vehicle communication device 39 enables data communication between the electric vehicle 31 and other devices installed outside thereof. In this embodiment, the communication device 39 establishes a communication line COM with the adapter 42. In this embodiment, the communication line COM is provided by a wireless LAN. The communication device 39 communicates with the adapter 42 by the third communication method. As the third communication method, a commonly used wireless LAN standard can be used. Further, it may be via a mobile phone line or the Internet.

The communication device 39 inputs information required for the second control method from the communication line LAN and transmits it to the communication line COM. The communication device 39 inputs predetermined information from the communication line COM, and controls the control device 36 or the charge / discharge circuit 35 via the communication line LAN. For example, in response to a signal input from the communication line COM, the communication device 39 defers charging of the battery 34 by the charge / discharge circuit 35 for a predetermined period.

  The adapter 42 is compatible with both the first control method and the second control method. The adapter 42 provides a connection device for charging that is connected to the power source 20 and the electric device 30 in order to charge the battery 34 of the electric device 30 from the power source 20. In addition to the same components 43, 44, 45, 46 as the adapter 41 adapted only to the first control scheme, the adapter 42 further includes an inlet 47 adapted to the second control scheme, an additional communication device 48, and a gateway. 49.

  According to this configuration, the power source 22 is connected to the electric vehicle 31 via the adapter 42. The electric vehicle 31 includes only an inlet 33 for AC power. Therefore, the electric vehicle 31 can receive a basic charging process based on the first control method from the power source 22 adapted to the second control method.

  Furthermore, information necessary for the second control method is communicated via the in-vehicle communication device 39, the additional communication device 48 provided in the adapter 42, and the gateway 49. Therefore, the electric vehicle 31 can utilize at least a part of additional functions provided in the second control method. Therefore, even when an electric vehicle 31 that conforms to the first control method and does not conform to the second control method is connected, a part of the functions of the second control method can be provided. In this embodiment, since the communication device 48 and the gateway 49 are provided in the adapter 42, the function can be expanded without changing the power source 22 and the electric vehicle 31.

In step 172, processing by the first communication method is started between the power supply 20 and the adapter 42. Specifically, communication using CPLT is started.

  In step 173, it is determined whether or not the output side of the adapter 42, that is, the connector 44 is connected to the electric vehicle 30. When the connector 44 is not connected to the electric vehicle 30, the connection 44 is awaited. If the connector 44 is connected to the electric vehicle 30, the process proceeds to step 174.

Specifically, communication using CPLT is started.

  In step 175, it is determined whether or not electric vehicle 30 is in a chargeable state. This determination is provided by the first communication method. This determination is also a process of determining whether or not the electric vehicle 30 can be connected to the power source 20. This determination is also a process of determining whether preparation of the electric vehicle 30 is completed. If the electric vehicle 30 is not in a chargeable state, it waits for the chargeable state. When the electric vehicle 30 is in a chargeable state, the process proceeds to step 176. In step 176, the process by the 2nd communication system between the power supply 22 and the adapter 42 is started. Specifically, communication using HPGP is started.

  In step 177, it is determined whether or not the second communication method is available. This determination is provided by determining whether HPGP is available. If the second communication method is not available, the process proceeds to step 184 described later. If the second communication method is available, the process proceeds to step 178.

  In step 178, power supply from the power source 20 to the adapter 42 based on the first control method is started. Specifically, power supply permitted by CPLT, that is, supply of AC power is started. In step 179, power supply from the adapter 42 to the electric vehicle 30 based on the first control method is started. Specifically, power supply permitted by CPLT, that is, supply of AC power is started. Steps 178 and 179 start power feeding from the power source 20 to the electric vehicle 30 based on the first control method.

  In step 180, power supply from the power source 22 to the adapter 42 based on the second control method is started. Specifically, power supply permitted by HPGP, that is, both supply of AC power and supply of DC power are started.

  In step 181, processing by the third communication method between the adapter 42 and the electric vehicle 30 is started. The third communication method is a vehicle communication method mounted on the electric vehicle 30. For example, it conforms to the communication standard of a vehicle-mounted wireless network. Specifically, communication using the communication line COM between the communication device 48 and the communication device 39 is started. Here, data required for an additional function in the advanced charging process that can be used only in the second control method is exchanged among the power source 22, the adapter 42, and the electric vehicle 30. In step 181, for example, the adapter 42 acquires information indicating the state of charge SOC of the battery 34 from the electric vehicle 30.

  The communication processing in step 181 can include the following processing, for example. The communication device 39 acquires necessary information from the communication line LAN. Further, the communication device 39 transmits information acquired via the communication line COM to the communication device 48. The communication device 48 controls the control device 46 based on the acquired information. In addition, the communication device 48 transmits information acquired via the gateway 49 to the power supply 22. The gateway 49 provides conversion from an in-vehicle communication standard capable of data communication via the communication line COM to a communication standard of the second communication method that the power supply 22 complies with. The gateway 49 transmits information to the control device 26 via a communication line between the adapter 42 and the control device 26. Here, information is transmitted to the control device 26 by power line communication used in the second communication method. The control device 26 provides an additional function based on the acquired information. For example, functions such as power supply selection and postponement of power supply to the electric vehicle 30 for appropriately maintaining the power supply / demand balance in the power grid are provided.

  The control device 26 transmits necessary information to the adapter 42. The gateway 49 acquires information from the power line communication line. The gateway 49 provides a conversion from the communication standard of the second communication method to which the power supply 22 conforms to an in-vehicle communication standard capable of data communication via the communication line COM. The communication device 48 controls the control device 46 based on the acquired information. In addition, the communication device 48 transmits information acquired via the gateway 49 to the communication device 39. The communication device 39 transmits the acquired information to the communication line LAN. The communication device 39 can control the charge / discharge circuit 35 based on the acquired information. For example, when the power supply from the power source 22 is postponed in order to properly maintain the power supply / demand balance in the power network, the charge / discharge circuit 35 is maintained in a standby state.

  In step 182, an advanced charging process based on the second control method is executed. For example, the above-described energy management charging process is executed. In step 183, it is determined whether or not the power processing between the power source 22 and the electric vehicle 30 has been completed. For example, in step 183, it is determined whether or not the state of charge SOC of the battery 34 has reached the target state of charge. When the power processing is completed, the series of processing ends. If the power process has not been completed, the process returns to step 181 to continue the advanced charging process based on the second control method.

  If the connector 25 is not connected in step 171, the process branches to step 184. In this case, it is considered that the plug 43 is connected to the power source 21. In step 184, a charging process based on the first control method is executed. Specifically, the charging process using the CPLT signal is provided by the control device 46. Therefore, when the plug 43 is connected to the power source 21, the adapter 42 provides the same function as the adapter 41. Therefore, the electric vehicle 30 is charged by the basic charging process based on the first control method.

  According to this embodiment, the electric vehicle 31 adapted only to the first control method can use the basic charging process provided by the first control method. Furthermore, the electric vehicle 31 can utilize at least a part of additional functions provided in the second control method.

  FIG. 7 shows the charging system 16 in the case where the electric vehicle 31 adapted only to the first control method is charged via the adapter 42 from the power source 21 adapted only to the first control method. As shown, the adapter 42 can provide a connection between the power source 21 and the electric vehicle 31. Therefore, the adapter 42 can be used as a substitute for the adapter 41.

  According to this configuration, the electric vehicle 31 and the adapter 42 can perform data communication via the communication device 39 and the communication device 48. Therefore, additional information can be used between the electric vehicle 31 and the adapter 42 in addition to the information used in the first control method. For this reason, the communication device 39 and the communication device 48 can be configured to provide additional functions.

  FIG. 8 shows the charging system 17 when charging the electric vehicle 32 that is also adapted to the second control method from the power source 21 that is adapted only to the first control method via the adapter 42. Such charging between different types of systems can be used when the connector 44 and the inlet 37 are configured to be connectable. The electric vehicle 32 can also be charged from the power source 21. Therefore, the adapter 42 can be used as a substitute for the adapter 41.

  According to this configuration, the electric vehicle 32 and the adapter 42 can perform data communication via the communication device 39 and the communication device 48. For this reason, in addition to the information used in the first control method, additional information can be used between the electric vehicle 32 and the adapter 42. For this reason, the communication device 39 and the communication device 48 can be configured to provide additional functions.
