Abstract
Methods and systems are provided for communicating operating conditions and operational limitations of an electric coupler that is external of a vehicle to the vehicle. In one example, functionality of a proximity detection circuit is enhanced to double as a serial communications link between a vehicle and an electric coupler.
Claims20
An electric coupler for an electric vehicle, comprising:
- an electric conductor electrically coupled a voltage divider circuit, a transistor, and circuitry configured to identify one or more attributes of the electric coupler.
A method for supplying electric power from a vehicle, comprising:
- sensing a voltage that is indicative of an electric coupler having serial communications capability via circuitry of the vehicle, where the voltage is sensed at an electric conductor;
- and
- requesting identification data for the electric coupler via circuitry of the vehicle.
An electric coupling system for an electric vehicle, comprising:
- an electrical plug included with the electric vehicle;
- a first circuit included in the electric vehicle, the first circuit in electrical communication with the electrical plug and configured to sense a voltage associated with a pin of the electrical plug and communicate with an external electric coupler via adjusting the voltage.
