Electric vehicle station equipment for grid-integrated vehicles
First Claim
1. A method for transferring power and information between a power grid and an electric vehicle, the method comprising:
- maintaining, by an electric vehicle station equipment (EVSE) separate from the electric vehicle and electrically coupled to the power grid, EVSE attributes;
establishing, by the EVSE, communication with an electric vehicle equipment (EVE) inside the electric vehicle;
transmitting, by the EVSE, the EVSE attributes to the EVE, the EVSE attributes including authorization to backfeed power to the power grid;
receiving, by the EVSE, an instruction from the EVE, the instruction automatically generated by the EVE based on the EVSE attributes, the instruction including a communication to backfeed the power to the power grid; and
energizing, by the EVSE, an electrical connector of the EVSE to electrically couple or decouple a corresponding electrical connector of the EVE with the power grid to supply power between the electric vehicle and the power grid in accordance with the instruction.

Abstract
Methods, systems, and apparatus transferring power between the grid and an electric vehicle are disclosed. The apparatus may include at least one vehicle communication port for interfacing with electric vehicle equipment (EVE) and a processor coupled to the at least one vehicle communication port to establish communication with the EVE, receive EVE attributes from the EVE, and transmit electric vehicle station equipment (EVSE) attributes to the EVE. Power may be transferred between the grid and the electric vehicle by maintaining EVSE attributes, establishing communication with the EVE, and transmitting the EVSE maintained attributes to the EVE.
