Hereinafter, an example of the embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a schematic view showing an example of a vehicle charging device 10 according to an embodiment of the present invention. FIG. 1 (A) shows the case of CHAdeMO in which the charging method supplies direct current to the vehicle, and FIG. 1 (B) shows the case of J1772 in which the charging method supplies alternating current to the vehicle.

The vehicle charging device 10 shown in FIG. 1 supplies the alternating current supplied from the system power 12 as a voltage conforming to the J1772 standard. If the AC supplied from the grid power 12 does not meet the J1772 standard, an AC power supply circuit is provided separately.

The DC power supply circuit 16 is a circuit that rectifies the alternating current supplied from the system power 12 to a direct current conforming to the CHAdeMO standard. Since the current supplied to the vehicle in CHAdeMO is a direct current of 50 to 500 V, the DC power supply circuit 16 converts the alternating current supplied from the system power 12 by the rectifier provided inside into a direct current of 50 to 500 V.

The direct current output by the DC power supply circuit 16 is energized to the second terminal 20B of the relay 20, and the alternating current supplied from the system power 12 is energized to the third terminal 20C of the relay 20. The first terminal of the relay 20 is connected to the CHAdeMO charging connector 40 via a power line in the charging cable 32.

When the exciting coil 24 is not energized, the relay 20 is connected to the first terminal 20A and the second terminal 20B as shown in FIG. 1A, and as a result, the charging cable 32 is connected to a DC power supply. The direct current output by the circuit 16 is supplied. Further, when the exciting coil 24 is energized, the relay 20 is connected to the first terminal 20A and the third terminal 20C as shown in FIG. 1 (B), and as a result, the charging cable 32 is connected to the system. The alternating current supplied from the electric power 12 is supplied.

The energization of the relay 20 to the exciting coil 24 is controlled by the relay control circuit 26. The relay control circuit 26 controls energization of the exciting coil 24 according to an electric signal from the sensor 70 for detecting whether or not the charging adapter 50 for J1772 is connected to the charging adapter accommodating portion 60 of the vehicle charging device 10. To do. More specifically, when the sensor 70 detects that the latch 58 fixed to the charging adapter accommodating portion 60 of the vehicle charging device 10 has been unlocked, the exciting coil 24 is energized and the charging cable 32 is connected to the system. Conducts the alternating current supplied from the electric power 12.

As will be described later, in the present embodiment, the connection portion 46 of the CHAdeMO charging connector 40 is connected to the connection portion 52 of the J1772 charging adapter 50 fixed to the charging adapter accommodating portion 60 of the vehicle charging device 10. When locked, the latch 58 of the charging adapter 50 for J1772 is unlocked. In this state, when the CHAdeMO charging connector 40 is pulled away from the housing of the vehicle charging device 10, the J1772 charging adapter 50 is fixed to the tip of the CHAdeMO charging connector 40. It can be removed from the charging adapter housing 60.

The sensor 70 is, for example, a piezoelectric sensor or the like, and detects the pressure when the latch 58 of the charging adapter 50 for J1772 is fitted to the charging adapter accommodating portion 60, and outputs an electric signal. In the present embodiment, when the sensor 70 detects the pressure when the latch 58 of the charging adapter 50 for J1772 is fitted to the charging adapter accommodating portion 60 and outputs an electric signal, the charging adapter for J1772 is output. It is considered that 50 is connected to the charging adapter accommodating portion 60 of the vehicle charging device 10. If the sensor 70 does not detect the pressure when the latch 58 of the charging adapter 50 for J1772 is fitted to the charging adapter housing 60 and does not output an electric signal, the charging adapter 50 for J1772 is a vehicle charging device. It is considered that it is not connected to the charging adapter accommodating portion 60 of 10. In FIG. 1, the sensor 70 is provided in the charging adapter accommodating portion 60 on the housing side of the vehicle charging device 10, but may be provided inside the charging adapter 50 for J1772 (sensors 70B, 70C). In such a case, the pressure when the J1772 charging adapter 50 is fixed to the charging adapter accommodating portion 60 is detected by the sensor 70B provided inside the J1772 charging adapter 50. Further, the sensor 70C detects the pressure when the CHAdeMO charging connector 40 is connected to the J1772 charging adapter 50. In the present embodiment, the sensor 70 is provided inside the charging adapter housing 60 (sensor 70), the charging adapter 50 for J1772 (sensors 70B, 70C), and the charging connector 40 for CHAdeMO (sensor 70D), respectively, and is provided in the sensor 70. The reliability of the operation of the vehicle charging device 10 may be ensured by providing the redundancy. When the sensors 70, 70B, 70C, and 70D are provided, one end of the J1772 charging adapter 50 is held by the charging adapter housing 60, and the CHAdeMO charging connector 40 is connected to the other end of the J1772 charging adapter 50. In this case, and when the J1772 charging adapter 50 and the CHAdeMO charging connector 40 are not connected and the J1772 charging adapter 50 is not held in the accommodating portion, it can be detected. In such a case, by stopping the output of the current, an electric shock accident can be prevented.

The relay control circuit 26 does not energize the exciting coil 24 when an electric signal is input from the sensor 70. The electric signal from the sensor 70 is also input to the charge control circuit 30. When an electric signal is input from the sensor 70, the charge control circuit 30 executes charge control by CHAdeMO and controls the DC power supply circuit 16.

Further, the sensor 70 stops the output of the electric signal when the latch 58 of the charging adapter 50 for J1772 is released from the mating with the charging adapter accommodating portion 60. The relay control circuit 26 energizes the exciting coil 24 when no electric signal is input from the sensor 70. The charge control circuit 30 executes charge control by J1772 when no electric signal is input from the sensor 70.

FIG. 2 is a schematic view showing an example of the CHAdeMO charging connector 40, the J1772 charging adapter 50, and the charging adapter accommodating portion 60 of the vehicle charging device 10 according to the present embodiment. The CHAdeMO charging connector 40 is also called a charging gun because the handle portion has a pistol grip shape, and is connected to the charging terminal of the vehicle when charging by CHAdeMO. The CHAdeMO charging connector 40 includes a connecting portion 52 of the charging adapter 50 for J1772 and a latch 48 that fits with the charging terminal of the vehicle at the upper part of the connecting portion 46, and the latch 48 pushes the lock button 42 in the direction of arrow A. It is locked by that. The CHAdeMO charging connector 40 further includes a release button 44, and when the release button 44 is pushed in the direction of arrow B, the latch 48 is unlocked.

A protective cover 54 is provided for this purpose.

Further, the charging adapter 50 for J1772 is provided with a charging adapter accommodating portion 60 at the other end and a connecting portion 56 connected to the charging terminal of the vehicle when charging by CJ1772, and the charging terminal of the vehicle and the charging terminal of the vehicle are provided above the connection portion 56. A latch 58 that fits with the connection portion 62 of the charging adapter accommodating portion 60 is provided. Further, the connection portion 62 is provided with a protective cover 68 for protecting the terminals when the charging adapter 50 for J1772 is not connected.

The charging adapter 50 for J1772 is provided with a terminal corresponding to the CHAdeMO charging connector 40 at one end and a terminal corresponding to the vehicle-side charging terminal corresponding to J1772 at the other end. The charging adapter 50 for J1772 internally converts the power line and signal line according to the CHAdeMO standard into the power line and signal line according to the J1772 standard.

Specifically, both CHAdeMO and J1772 have a total of two power lines, and the upper limit voltage is 500V for CHAdeMO and 240V for J1772, so the power line for CHAdeMO can be diverted to J1772 as it is. This also applies to the charging cable 32, and even if the first terminal 20A and the third terminal 20C of the relay 20 are connected and the charging cable 32 is energized with alternating current corresponding to the J1772 standard, the charging cable 32 If the power line is compatible with CHAdeMO, the power line can be used as it is in J1772.

In CHAdeMO, CAN is used as the control signal communication method as described above, but during charging, both the vehicle side and the vehicle charging device 10 monitor the abnormality, so the vehicle side detects the abnormality. When it is detected, it is provided with a signal line for communicating with a Pilot signal in addition to the two signal lines for CAN signals as a transmission path for transmitting it to the charger side. There are a total of five signal lines for communication using the Pilot signal, and some of these signal lines can be applied to the transmission and reception of the control signal of the J1772. In J1772, a part of the control signal is transmitted and received using the power line, but since the physical standard of the power line for CHAdeMO is not much different from J1772, all the control signals of J1772 are transmitted and received by the power line and signal line for CHAdeMO. It is possible to do.

Therefore, in the present embodiment, the CHAdeMO-compatible power line is used as it is in the J1772, and a part of the CHAdeMO-compatible signal line is used in the J1772 as the signal line. Since the change of the charging method is executed by the relay control circuit 26 and the charging control circuit 30 in the vehicle charging device 10, there is no circuit such as a converter for converting alternating current into direct current inside the charging adapter 50 for J1772. As a result, the J1772 charging adapter 50 can be made smaller and lighter, the burden on the operator during charging is reduced, and the charging operation can be performed easily and reliably.
