Control pilot detection circuit
First Claim
Patent Images
1. A control pilot detection circuit for use in providing a control pilot wake-up signal to a controller of a vehicle charging system, the controller relying on the control pilot wake-up signal to facilitate charging a high voltage battery of a vehicle, the control pilot detection circuit comprising:
- a wake-up circuit configured to receive a control pilot signal, the control pilot signal having a frequency for a period of time, the wake-up circuit processing the control pilot signal to output the control pilot wake-up signal to the controller, the control pilot wake-up signal being output as a pulse that begins after a beginning of the period of time and completes prior to an ending of the period of time.

Abstract
A control pilot detection circuit operable with a control pilot signal provided from an electric vehicle supply equipment (EVSE) system to facilitate output of a control pilot wake-up signal. The control pilot wake-up signal may be operable with a controller to facilitate controlling operations of a vehicle charging system, such as to facilitate charging a high voltage battery included within a vehicle.

8. A vehicle charging system comprising:
-
an on-board charger operable charging a high voltage battery of a vehicle with AC energy provided through an electric vehicle supply equipment (EVSE) system, a controller of the on-board charger requiring receipt of a control pilot wake-up signal in order to facilitate charging the high-voltage battery; and a wake-up circuit configured to receive a control pilot signal provided through the EVSE system, the wake-up circuit processing the control pilot signal to output the control pilot wake-up signal to the controller, the control pilot wake-up signal being output as a pulse that begins after receipt of the control pilot signal and completes prior to terminating receipt of the control pilot signal. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
