Charging system, vehicle, charge control device, and charging method
A charging system includes: a switch device and a control device. Each of charging ports is provided with a lid configured to open and close a corresponding one of the charging ports. The control device is configured to determine whether a predetermined charge prohibition condition is satisfied before starting charging an electric energy storage device using any one of the charging ports, and when the predetermined charge prohibition condition is satisfied, keep each of power paths from the charging ports to the electric energy storage device disconnected. The predetermined charge prohibition condition is satisfied when the lid of at least one charging port that is included in the charging ports and that is other than the charging port to be used is open.
1 . A vehicle comprising:
an electric energy storage device;
a DC charging inlet to which a DC charging connector is configured to be connected;
a DC charging door sensor configured to determine when a DC charging door blocks charging using the DC charging connector;
an AC charging inlet to which an AC charging connector is configured to be connected;
an AC charging door sensor configured to determine when an AC charging door blocks charging using the AC charging connector;
a charging circuit that is connected to the AC charging inlet and that converts alternating-current power into direct-current power;
a shared wire through which direct-current power from the DC charging inlet and direct-current power from the charging circuit flow;
only one relay that is located in both an electrical path between the DC charging inlet and the electric energy storage device and an electrical path between AC charging inlet and the electric energy storage device, the relay being provided on the shared wire; and
a control circuit configured to:
detect whether the DC charging connector is inserted into the DC charging inlet;
detect whether the AC charging door sensor indicates that the AC charging door blocks charging using the AC charging connector;
in response to a determination that the DC charging connector is inserted into the DC charging inlet, and only if the AC charging door sensor indicates that the AC charging door blocks charging using the AC charging connector, cause electric power to be supplied from the DC charging connector to the energy storage device;
detect whether the AC charging connector is inserted into the AC charging inlet;
detect whether the DC charging door sensor indicates that the DC charging door blocks charging using the DC charging connector; and
in response to a determination that the AC charging connector is inserted into the AC charging inlet, and only if the DC charging door sensor indicates that the DC charging door blocks charging using the DC charging connector, cause electric power to be supplied from the AC charging connector to the energy storage device.
2 . The vehicle according to claim 1 , wherein the control circuit is configured to:
in response to a determination that the DC charging connector is inserted into the DC charging inlet, set the relay in an ON state so electric power is supplied from the DC charging inlet to the electric energy storage device, and
turn the charging circuit OFF so an electric connection between the AC charging inlet and the electric energy storage device is disconnected.
3 . The vehicle according to claim 1 , further comprising:
a vehicle body including a first side surface and a second side surface that are arrayed in a vehicle width direction, wherein
the DC charging inlet and the AC charging inlet are provided on the first side surface.
4 . The vehicle according to claim 1 , further comprising:
a vehicle body including a first side surface and a second side surface that are arrayed in a vehicle width direction; and
another DC charging inlet to which another DC charging connector other than the DC charging connector is configured to be connected, wherein
the DC charging inlet and the AC charging inlet are provided on the first side surface, and
the other DC charging connector is provided on the second side surface.
5 . The vehicle according to claim 4 , further comprising:
another relay that is provided between the other DC charging inlet and the electric energy storage device.
