Abstract
A vehicle includes control pilot circuitry, connected with a charge port, that carries a control pilot signal from electric vehicle supply equipment, and a controller that exits a sleep mode and increases power consumption responsive to changes in the control pilot signal while a plug of the electric vehicle supply equipment is mated with the charge port and an accumulated time associated with the changes remains less than a predefined value.
Claims17
A vehicle comprising:
- a charge port configured to receive a plug of electric vehicle supply equipment;
- control pilot circuitry connected with the charge port and configured to carry a control pilot signal from the electric vehicle supply equipment;
- and
- a controller programmed to exit a sleep mode and increase power consumption responsive to changes in the control pilot signal while the plug is mated with the charge port and an accumulated time associated with the changes remains less than a predefined value, and to remain in the sleep mode regardless of the changes while the plug is mated with the charge port after the accumulated time exceeds the predefined value.

A method comprising:
- by a controller, exiting a sleep mode and increasing power consumption responsive to changes in a control pilot signal from electric vehicle supply equipment while a plug of the electric vehicle supply equipment is mated with a vehicle charge port and an accumulated time associated with the changes remains less than a predefined value, and remaining in sleep mode regardless of the changes while the plug is mated with the charge port after the accumulated time exceeds the predefined value.
A vehicle charge system comprising:
- a controller programmed to selectively exit a sleep mode and enter a wake mode based on an accumulated number of changes in a control pilot signal from electric vehicle supply equipment such that the controller remains in the sleep mode regardless of the number of changes after the accumulated number exceeds a predefined value.
