## 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.

## Claims

### Claim 1

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.

### Claim 2 (depends on 1)

The vehicle of claim 1, wherein the controller is further programmed to reset the accumulated time to zero responsive to occurrence of a predefined duration of continuous charging.

### Claim 3 (depends on 1)

The vehicle of claim 1, wherein the controller is further programmed to reset the accumulated time to zero responsive to the plug being removed from the charge port.

### Claim 4 (depends on 1)

The vehicle of claim 1, wherein the controller is further programmed to exit the sleep mode and increase power consumption while the plug is mated with the charge port after the accumulated time exceeds the predefined value responsive to presence of a vehicle activation signal.

### Claim 5 (depends on 1)

The vehicle of claim 1, wherein the controller is further programmed to generate an alert after the accumulated time exceeds the predefined value.

### Claim 6 (depends on 1)

The vehicle of claim 1, wherein the controller is further programmed to increment the accumulated time while the controller is in a wake mode but not while the controller is in the sleep mode.

### Claim 7

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.

### Claim 8 (depends on 7)

The method of claim 7 further comprising resetting the accumulated time to zero responsive to occurrence of a predefined duration of continuous charging.

### Claim 9 (depends on 7)

The method of claim 7 further comprising resetting the accumulated time to zero responsive to the plug being removed from the charge port.

### Claim 10 (depends on 7)

The method of claim 7 further comprising exiting the sleep mode and increasing power consumption while the plug is mated with the charge port after the accumulated time exceeds the predefined value responsive to presence of a vehicle activation signal.

### Claim 11 (depends on 7)

The method of claim 7 further comprising generating an alert after the accumulated time exceeds the predefined value.

### Claim 12 (depends on 7)

The method of claim 7 further comprising incrementing the accumulated time while the controller is in a wake mode but not while the controller is in the sleep mode.

### Claim 13

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.

### Claim 14 (depends on 13)

The vehicle charge system of claim 13, wherein the controller is further programmed to reset the accumulated number to zero responsive to occurrence of a predefined duration of continuous charging.

### Claim 15 (depends on 13)

The vehicle charge system of claim 13, wherein the controller is further programmed to reset the accumulated number to zero responsive to a plug of the electric vehicle supply equipment being removed from a charge port.

### Claim 16 (depends on 13)

The vehicle charge system of claim 13, wherein the controller is further programmed to exit the sleep mode and enter the wake mode after the accumulated number exceeds the predefined value responsive to presence of a vehicle activation signal.

### Claim 17 (depends on 13)

The vehicle charge system of claim 13, wherein the controller is further programmed to generate an alert after the accumulated number exceeds the predefined value.
