  FIG. 1 shows a vehicle to which an embodiment of the present invention can be applied. In FIG. 1, a vehicle 1 that is an electric vehicle (EV) has a charging / feeding unit 3 as a charging / feeding device at the front and rear of a vehicle body 2. The charging / feeding unit 3 includes an AC power feeding outlet 4 that is a feeding unit shown in FIG. 2, and a normal charging inlet 5 and a quick charging inlet 6 that are charging units shown in FIG. 3. Further, the charging / feeding unit 3 includes a lid 17 that can be freely opened and closed, a charging lid 7B, an outlet 4 and a receptacle 17A that is integrally formed with the vehicle body 2 that supports the feeding lid 7A so that it can be opened and closed. A housing portion 17B formed integrally with the vehicle body 2 that houses the inlets 5 and 6 and supports the charging lid 7B so as to be freely opened and closed, a switching unit and a control unit, which will be described later, are provided.

The outlet 4 is fixed to the vehicle body 2 and is connected to a normal household 100V plug (not shown), so that power is supplied from an after-mentioned driving battery to an external home appliance as an external device.
The normal charging inlet 5 is fixed to the vehicle body 2 and is connected to an AC normal charging connector (not shown) so that a driving battery, which will be described later, is normally charged from an external power source as an external device.
The quick charge inlet 6 is fixed to the vehicle body 2, and is connected to a direct current quick charge connector (not shown), so that a drive battery described later is rapidly charged from an external power source as an external device.
The outlet 4 and the inlets 5 and 6 are respectively provided with switches 21, 22, and 23 that output signals to the control means described later when plugs and connectors are connected.

An instrument panel (not shown) in the passenger compartment inside the vehicle body 2 is provided with a start switch 8 as switching means operated by the driver. The start switch 8 selectively occupies a ready-on state in which the vehicle 1 can travel and the in-vehicle device can be used, and a ready-off state in which the vehicle 1 cannot travel and the in-vehicle device can be used.
Further, a drive system 20 that controls the operation of a drive motor 12 and a drive battery 10 described later is provided inside the vehicle body 2 and includes an ECU 9 as a control means. The ECU 9 is composed of a well-known microcomputer having a CPU, ROM, RAM, I / O port, etc. (not shown). The drive system 20 occupies an activated state in the ready-on state and a stopped state in the ready-off state.
Further, a known shift device 24 having a parking range (hereinafter referred to as “P range”) is disposed inside the vehicle body 2.
Note that when the drive system 20 is in the ready-on state, the vehicle can be run immediately and the engine can be started in some cases, but power consumption occurs because the system is in the activated state. In the ready-off state, no power consumption is generated, but in order to travel, it is necessary to shift to the ready-on state and the vehicle cannot travel immediately.

FIG. 4 shows a control block diagram of the drive system 20. In the figure, an ECU 9 includes a contactor 11 connected to a driving battery 10 as a battery and a motor for driving the vehicle 1 based on a signal from the start switch 8 and a connection signal sent from the outlet 4 and each of the inlets 5 and 6. Connected to a drive motor 12 as an inverter, connected to an outlet 4 to which AC electrical equipment is connected, connected to a DCAC inverter 14 for converting DC to AC, and connected to a normal charging inlet 5 to which an AC charging connector is connected. The operation of the ACDC inverter 15 for converting DC to DC and the operation of the contactor 16 connected to the quick charging inlet 6 to which the DC charging connector is connected are controlled.
The contactor 11 is in a connected state when the start switch 8 is in an on state, and in a disconnected state when the start switch 8 is in an off state, and a connector is connected to one of the inlets 5 and 6 when the start switch 8 is in an off state. Then, the connection operation is performed in response to the connector connection signal. When the contactor 11 is connected, the ECU 9 can obtain the remaining charge amount information from a charge amount detection means (not shown).

The operation of the charging / feeding device in the first embodiment of the present invention will be described.
First, the power feeding operation will be described based on the flowchart shown in FIG.
The user of the vehicle 1 opens the power supply lid 7A and connects the plug to the outlet 4 as shown in FIG. When the plug is connected and the switch 21 detects the plug (ST01), the ECU 9 determines whether or not the start switch 8 is in a ready-on state (ST02). Here, if the start switch 8 is in a ready-on state, the contactor 11 is connected, so that the driving battery 10 and the outlet 4 are connected via the DCAC inverter 14, so that a power feeding operation is performed from the outlet 4. (ST03).
When the ECU 9 determines that the start switch 8 is in the ready-off state in step ST02, the ECU 9 automatically changes the start switch 8 to the ready-on state (ST04), whereby the contactor 11 is connected and the power feeding operation is performed (ST03). ).

Next, the charging operation will be described based on the flowchart shown in FIG.
The user of the vehicle 1 opens the charging lid 7B as shown in FIG. 3 to charge from each of the inlets 5 and 6, and connects the normal charging inlet 5 to the normal charging connector or the quick charging inlet 6. Connect the quick-charge connector to it. When any connector is connected and any of the switches 22 and 23 detects the connector (ST11), the ECU 9 determines whether or not the start switch 8 is in a ready-off state (ST12). If the start switch 8 is in the ready-off state, the ECU 9 receives a signal from either of the switches 22 and 23 to connect the contactor 11, and the drive battery 10 and each of the inlets 5 and 6 are connected via the ACDC inverter 15. Or directly connected, power feeding operation is performed from each of the inlets 5 and 6 (ST13).
When the ECU 9 determines that the start switch 8 is in the ready-on state in step ST12, the ECU 9 automatically changes the start switch 8 to the ready-off state (ST14), and after this, the contactor 11 is disconnected, and the same as described above. The charging operation is performed (ST13).

According to the first embodiment, if the outlet 4 is used for power supply, the drive system 20 is in a ready-on state, and if the inlets 5 and 6 are used for charging, the drive system 20 is in a ready-off state. It is possible to recognize whether the driving system 20 is in a power feeding operation or a charging operation.
In the above embodiment, the connection between the connector and the inlet is detected by providing the switches 22 and 23 in each of the inlets 5 and 6, but as another embodiment, when the connector is connected to the inlet, the inlet is connected from the connector. It is good also as a structure which detects the connection of a connector and an inlet by transmitting to the control means the connection signal that the connector and the inlet were connected by the signal line extended to control means, such as ECU9.

In the above embodiment, the switching operation in which the power feeding operation is in the ready-on state and the charging operation is in the ready-off state has been described. However, the reverse configuration may be used as long as the power feeding operation or the charging operation can be recognized.
When the power supply operation is in the ready-on state, the power balance of the drive battery 10 can be constantly monitored, and the occurrence of problems such as inability to start the drive system 20 and inability to travel the vehicle 1 due to insufficient charge is suppressed. In addition, when the ready operation is performed in the charging operation, the generation of power consumption of the drive system 20 is suppressed, so that the charging efficiency can be improved.
Further, when the drive system 20 is in a ready-on state by a power feeding operation or a charging operation, the shift device 24 may be shifted to the P range when the shift device 24 is not in the P range. According to this configuration, since the vehicle cannot be started unless the P range is released, it is possible to prevent the vehicle from starting in a state where the plug or the connector is connected.

  Next, a second embodiment of the present invention will be described. In the second embodiment, only one of the power feeding operation and the charging operation can be performed, the charging operation is prohibited when performing the power feeding operation, and the power feeding operation is performed when performing the charging operation. This is different from the first embodiment described above in that it is prohibited to perform the above. The operation of the charging / feeding unit 3 in the second embodiment will be described based on the flowchart shown in FIG.

  The ECU 9 first determines whether or not a plug is connected to the outlet 4 (ST21). If it is determined that the plug is connected by turning on the switch 21, the ECU 9 determines whether or not the start switch 8 is in a ready-on state (ST22). If it is determined that the start switch 8 is in the ready-on state, the ECU 9 prohibits connection of the connector to the inlets 5 and 6 (ST23). The prohibition of connection here means, for example, prohibition of physical connection in which the inlets 5 and 6 are covered with a shielding member or the like, and electrical connection with the connectors connected to the inlets 5 and 6. Including various cases such as prohibition of connection. Thereafter, the ECU 9 performs a power feeding operation in the same manner as described above (ST24). If the start switch 8 is in the ready-off state in step ST22, the ECU 9 sets the start switch 8 in the ready-on state (ST25), and proceeds to step ST23.

  If no plug is detected in step ST21, the ECU 9 determines whether or not a connector is connected to one of the inlets 5 and 6 (ST26). Here, when the connection of the connector is not detected, the process returns to step ST21 again. When it is determined that the connector is connected by turning on the switch 22 or the switch 23, the ECU 9 determines whether or not the start switch 8 is in a ready-off state (ST27). If it is determined that the start switch 8 is in the ready-off state, the ECU 9 prohibits connection of the plug to the outlet 4 (ST28). This connection prohibition also includes various prohibitions such as a physical prohibition and an electrical prohibition. Thereafter, the ECU 9 performs a charging operation in the same manner as described above (ST29). If the start switch 8 is in the ready-on state in step ST27, the ECU 9 sets the start switch 8 in the ready-off state (ST30), and proceeds to step ST28.

According to the second embodiment, since it is prohibited to perform the power feeding operation and the charging operation at the same time, for example, the power feeding operation and the charging operation are performed at the same time, and which operation is performed is recognized. It is prevented from becoming impossible.
In addition, as physical connection prohibition of the said embodiment, lock mechanism 18A, 18B which hold | maintains each charging lid 7A, 7B in the obstruction | occlusion state is provided in each accommodating part 17A, 17B (refer FIG. 2, FIG. 3). The ECU 9 holds the charging lid 7B closed by the lock mechanism 18B when the outlet 4 is used, and the charging lid 7A by the lock mechanism 18A when any of the inlets 5 and 6 is used. Is kept closed. With this configuration, it is possible to obtain the same effects as those of the second embodiment.
When either the outlet 4 or one of the inlets 5 and 6 is used, the charging lid on the side that is not used may be released. In this case, if the charging lid on the side not in use is not closed, it cannot be held in the closed state by the lock mechanism. Therefore, a mechanism for automatically closing the opened charging lid may be added.

Although each embodiment mentioned above showed the case where the vehicle 1 was an electric vehicle, respectively, as the vehicle 1, the plug-in hybrid vehicle (PHEV) carrying an engine may be sufficient.
FIG. 8 shows a control block diagram of the drive system 20 when the present invention is applied to a plug-in hybrid vehicle according to the third embodiment of the present invention. Compared with the configuration shown in FIG. 4, the third embodiment has a generator 30 connected to the inverter 13 and an engine 31 connected to the generator 30, and the ECU 9 performs drive control of the engine 31. Only the difference is, and the other configurations are the same.

  According to the third embodiment, since the vehicle 1 has the engine 31, the engine 31 can be started when the start switch 8 is in the ready-on state, and the engine 31 cannot be started when the start switch 8 is in the ready-off state. It becomes. For this reason, if the power feeding operation is set to the ready-on state, the engine 31 can be started and used as a generator, so that the remaining charge amount of the driving battery 10 may be insufficient due to the power supply and the charge amount may be insufficient. In such a case, the ECU 9 can start the engine 31 to perform a charging operation, and can reliably avoid the occurrence of insufficient charging.

  In each of the above-described embodiments, as shown in FIG. 9, when the plug is connected to the outlet 4, a connection display 19 that allows the user of the vehicle 1 to visually recognize the plug may be provided in the accommodating portion 17 </ b> A. By providing this connection display 19, it can be reliably transmitted to the user of the vehicle 1 that the plug is connected to the outlet 4, and the outlet 4 is connected to the outlet 4 as shown in the first embodiment. When provided outside the passenger compartment, the vehicle 1 can be prevented from traveling with the plug connected to the outlet 4. In this example, the connection display 19 is provided in the housing portion 17A. However, the connection display 19 may be arranged at a position that can be seen from the driver seat or the passenger seat, such as an instrument panel or a dashboard.
