A known data communication for automatically coupling the second power receiving coupler 60 to the second power receiving coupler 60 is performed. When the two couplers 58 and 60 are connected, the ECU 31 outputs a control signal S5 to the second controller 54 via the signal lines L3 and L4.

Therefore, when performing the charging operation using the second stationary charging device 51, the charging operation using the automatic second stationary charging device 51 is selected by the operation switch 34. Then, the second power transmitting coupler 58 is automatically coupled to the second power receiving coupler 60. Then, the ECU 31 controls the signal lines L3 and L3 so that the battery B is charged in an optimal state.
A control signal S5 is output to the second controller 54 via L4. As a result, the DC power generated from the commercial AC power supply E via each circuit is applied to the battery B, and the battery B is charged.

Therefore, the vehicle-mounted charging device 59 of the third embodiment corresponds to the first stationary charging device 1 that couples the power transmission coupler to the power receiving coupler by a manual method, and the first charging device provided in the device. A first power receiving coupler 12 that can be coupled to the power transmitting coupler 11 in a conductive manner is provided. In addition, a second power receiving coupler that corresponds to the second stationary charging device 51 that couples the power transmitting coupler to the power receiving coupler by the automatic method and that can be coupled to the second power transmitting coupler 58 provided in the device by the conductive method 6
0 is provided. Therefore, the same operation and effect as the operation and effect (1) in the first embodiment can be obtained.

The above embodiments can be modified as follows, for example. In the first embodiment, the first power transmission coupler 11 is connected to the rectifier circuit 10 connected to the transformer 9, but the first power transmission coupler 11 may be connected to the commercial AC power supply E. . That is, the first power transmission coupler 11 and the first power receiving coupler 12 may be provided between the commercial AC power supply E and the rectifier circuit 5 connected to the power supply E. In this case, only the first power transmission coupler 11 is provided in the first stationary charging device 1, and all other components subsequent thereto are provided in the vehicle-mounted charging device 3. Then, the rectifier circuit 1 connected to the transformer 9
0 and the rectifier circuit 18 connected to the second power receiving coupler 20 can be shared.

In the third embodiment, in both the first stationary charging device 1 and the second stationary charging device 51, the rectifier circuit 1 connected to the transformers 9 and 56
Although the first and second power transmitting couplers 11 and 58 are connected to 0 and 57, both power transmitting couplers 11 and 58 may be connected to the commercial AC power source E, respectively.

That is, as shown in FIG. 4, the second power transmission coupler 58 may be configured to be connected to the commercial AC power supply E. In other words, the second power transmitting coupler 58 and the second power receiving coupler 60 may be provided between the commercial AC power supply E and the rectifier circuit 52 connected to the power supply E. In this case, the second
The stationary charging device 51 is provided with only the second power transmission coupler 58, and all other components subsequent thereto are the vehicle-mounted charging device 5.
9. Note that the first power transmission coupler 11 may be connected to the commercial AC power supply E instead of the second power transmission coupler 58.

As shown in FIG. 5, both the first and second power transmission couplers 11 and 58 may be connected to the commercial AC power supply E. In this case, only the power transmission coupler is provided in each of the first and second stationary charging devices 1 and 51, and all other components subsequent thereto are shared and provided in the vehicle-mounted charging device 59.

In the first and third embodiments, when the couplers 11, 12, 58, and 60 are coupled to each other in a conductive manner, a resonance type is used as an electrical configuration for generating a DC power supply to be applied to the battery B. Although the inverter circuits 8, 55 and the like are used, the configuration may be another configuration.

For example, a commercial AC power supply E may be supplied to a leakage transformer via a breaker, and a DC voltage generated by rectifying the generated induced voltage may be applied to the battery B. According to this configuration, the control of the current required by the change in the capacity of the battery B is generally performed automatically, though roughly. Therefore, it is not necessary to provide the ECU 31.

The SCR in which the diodes of the rectifier circuits 10 and 57 connected to the transformers 9 and 56 are replaced with thyristors
May be used. According to this configuration, more accurate current control can be performed as compared with the configuration using the leakage transformer.

In the first embodiment, the operation of charging the battery B using the first stationary charging device 1 is a manual operation, and the operation of using the second stationary charging device 2 is an automatic operation. However, this work method may be reversed. That is, the case of the first stationary charging device 1 may be an automatic method, and the case of the second stationary charging device 2 may be a manual method.

In the first and third embodiments, when the couplers 11, 12, 58, and 60 are connected to each other in a conductive manner, the ECU 31 sends the first and second controllers 7, 12 via the signal lines L1 to L4. Although the control signal S5 is output to 54, the control signal S5 may be transmitted via a communication circuit. In this case, the first and second controllers 7 and 54 need to be provided with a receiving unit that receives the transmitted control signal S5.

In each of the above embodiments, the electric vehicle is described as an example of the battery vehicle. However, the battery vehicle is not limited to the electric vehicle. It may be a truck, an industrial vehicle, or the like.
