FIG. 3 is a perspective view of a pallet 18 that is charged with an electric vehicle. The pallet 18 is provided with power receiving contacts 22a and 22b on both sides in the longitudinal direction and outlets 23a and 23b on the upper surface of the side edge, and the power receiving contacts 22a and 22b and the outlets 23a and 23b are electrically connected. Has been. The outlets 23a and 23b are electrically connected to the outlets 23a and 23b by connecting one end of a charging cable attached to the electric vehicle and connecting the other end to the electric vehicle. When the pallet 18 is stored in the parking chamber 17 with the outlets 23a and 23b and the electric vehicle connected as described above, as described above, the power supply contact 21 of the parking chamber 17 is connected to any one of the power receiving contacts 22a and 22b. Electric power is supplied, and the electric vehicle is charged via the outlet 23a or 23b and the charging cable. On the pallet 18, connection detectors 24a and 24b are further provided in the vicinity of the outlets 23a and 23b, thereby detecting that the charging cable is connected to the outlet 23a or 23b.

  FIG. 4 is an electric circuit diagram showing connections between the devices arranged on the pallet 18. In the figure, 22a and 22b are power receiving contacts, and power is supplied to either one of them. 23a and 23b are outlets, and 50a is a contact that is closed when the connection detector 24a detects that the charging cable is connected to the outlet 23a. Similarly, 50b is a charging cable that is connected to the outlet 23b. This contact is closed when the connection detector 24b detects this.

  Furthermore, in this electric circuit diagram, 40a, 40b, 40c, and 40d are contacts of the electromagnetic contactor that is closed by energizing the coils 30a, 30b, 30c, and 30d of the electromagnetic contactor, and 41a, 41b, 41c, and 41d are The contacts of the electromagnetic contactor that is opened by energizing the coils 30a, 30b, 30c, and 30d. Then, the contacts 30a and 41a operate by the coil 30a, the contacts 40b and 41b by the coil 30b, the contacts 40c and 41c by the coil 30c, and the contacts 40d and 41d by the coil 30d, respectively.

  Next, the operation of this electric circuit will be described. First, in the state shown in the figure, no charging cable is connected to any of the outlets 23a and 23b, and the contacts 50a and 50b of the connection detectors 24a and 24b are open. In this state, no power is supplied to any one of the power receiving contacts 22a, 22b, and any coil 30a, 30b, 30c, 30d is not energized. Therefore, the contacts 40a, 40b, 40c, 40d of the electromagnetic contactor are not It remains open and neither the outlet 23a, 23b is energized.

  Next, when the charging cable is connected to the outlet 23a, the contact 50a of the connection detector 24a is closed. In this state, when power is supplied to one power receiving contact 22a, the coil 30d is energized to close the contact 40d and open the contact 41d. As a result, the outlet 23a is energized from the power receiving contact 22a through the contact 41c and the contact 40d. On the other hand, in the power supply circuit from the power receiving contact 22a to the outlet 23b at this time, both the contacts 41d and 40c on the circuit are open, and therefore the outlet 23b is not energized. Subsequently, when power is supplied to the other power receiving contact 22b with the contact 50a closed, the coil 30b is energized to close the contact 40b and open the contact 41b. Thereby, electricity is supplied from the power receiving contact 22b to the outlet 23a via the contact 41a and the contact 40b. At this time, in the power supply circuit from the power receiving contact 22b to the outlet 23b, both the contacts 41b and 40a on the circuit are open, and therefore the outlet 23b is not energized.

  Next, when the charging cable is connected to the opposite outlet 23b, the contact 50b of the connection detector 24b is first closed. In this state, when power is supplied to one power receiving contact 22a, the coil 30c is energized to close the contact 40c and open the contact 41c. As a result, the outlet 23b is energized from the power receiving contact 22a through the contact 41d and the contact 40c. On the other hand, in the power supply circuit from the power receiving contact 22a to the outlet 23a at this time, both the contacts 41c and 40d on the circuit are open, and therefore the outlet 23a is not energized. Subsequently, when power is supplied to the other power receiving contact 22b with the contact 50b closed, the coil 30a is energized to close the contact 40a and open the contact 41a. Thereby, electricity is supplied from the power receiving contact 22b to the outlet 23b via the contact 41b and the contact 40a. At this time, in the power supply circuit from the power receiving contact 22b to the outlet 23a, both the contacts 41a and 40b on the circuit are open, and therefore the outlet 23b is not energized.

  Next, a case where both the contacts 50a and 50b of the connection detectors 24a and 24b are closed will be described. In this case, when electric power is supplied to one power receiving contact 22a, the coil 30d is energized to close the contact 40d and open the contact 41d. At the same time, the coil 30c is energized to close the contact 40c and open the contact 41c. As a result, the power supply circuit from the power receiving contact 22a to the outlets 23a and 23b is cut off when both of the contacts 41c and 41d on the circuit are opened, and therefore neither of the outlets 23a and 23b is energized. Next, when power is supplied to the other power receiving contact 22b, the coil 30a is energized to close the contact 40a and open the contact 41a. At the same time, the coil 30b is energized to close the contact 40b and open the contact 41b. Thereby, in the power supply circuit from the power receiving contact 22b to the outlets 23a and 23b, both of the contacts 41a and 41b on the circuit are opened and shut off, and therefore neither of the outlets 23a and 23b is energized.

  As described above, in the plurality of outlets provided in the pallet 18, when the charging cable is not connected to any outlet, each outlet is not energized, and when the outlet is used. Is energized only to the outlet connected to the charging cable, not to the outlet that is not used. Therefore, the possibility of occurrence of a malfunction due to a leakage or short circuit in an unused outlet is reduced. In addition, when the connection of the charging cable to the outlet is detected in duplicate, there is a possibility of a malfunction of the electric circuit, and in this case, all the outlets are not energized, which is safe.

In the above embodiment, the connection detectors 24a and 24b detect the connection of the charging cable and thereby selectively energize the outlets 23a and 23b. However, the connection detectors 24a and 24b are replaced by manual operation. A selection switch may be provided on the pallet 18, and the outlets 23a and 23b may be selected and operated by operating the manual selection switch. Hereinafter, a configuration using a manual selection switch will be described as a reference example .

First, although not shown, the pallet 18 includes a manual selection switch, and the user selects one of the outlets 23a and 23b to be energized by operating the manual selection switch. FIG. 5 is an electric circuit diagram when a manual selection switch is used. In the figure, similarly to the above, 23a and 23b are outlets, and 22a and 22b are power receiving contacts to which power is supplied to either one of them. 51a and 51b are contacts of the manual selection switch 51, which operate in conjunction with each other. Next, 32a, 32b, 32c, and 32d are coils of the magnetic contactor, and 42a, 42b, 42c, and 42d are contacts that are closed when the corresponding coils are energized. Each coil and contact corresponds to 32a and 42a, 32b and 42b, 32c and 42c, 32d and 42d, respectively.

  In this electric circuit, when the outlet 23a side is selected by the manual selection switch 51, the contacts 51a and 51b both close the lower contacts. In this state, when power is supplied to the power receiving contact 22a, the coil 32d is energized to close the contact 42d, and the power receiving contact 22a is energized to the outlet 23a via the contact 42d. At this time, the contact 42c is open, so that the outlet 23b is not energized. Subsequently, in the same state where the manual selection switch 51 is selected to the outlet 23a side, when power is supplied to the power receiving contact 22b, the coil 32b is energized and the contact 42b is closed, and the power receiving contact 22b passes through the contact 42b. The outlet 23a is energized. At this time, the contact 42a is open, so that the outlet 23b is not energized.

Next, when the outlet 23b side is selected in the manual selection switch 51, both the contacts 51a and 51b close the upper contacts. When power is supplied to the power receiving contact 22a in this state, the coil 32c is energized to close the contact 42c, and the power receiving contact 22a is energized to the outlet 23b via the contact 42c. At this time, the contact 42d is open, and therefore, the outlet 23a is not energized. Subsequently, in the same state where the manual selection switch 51 is selected to the outlet 23b side, when power is supplied to the power receiving contact 22b, the coil 32a is energized and the contact 42a is closed, and the power receiving contact 22b passes through the contact 42a. The outlet 23b is energized. At this time, the contact 42b is open, so that the outlet 23a is not energized.

  Even when the manual selection switch is employed as described above, since only the selected outlet is energized, it is possible to reduce the possibility of occurrence of a malfunction due to leakage or short circuit in the unused outlet. Further, in the case of this configuration, the number of parts can be reduced, so that it can be configured at low cost.
