System for identifying an electric vehicle connected to electric vehicle service equipment
First Claim
1. A method for identifying an electric vehicle connected to EVSE comprising:
- connecting the EVSE via a cable to the electric vehicle;
applying power from the EVSE to the electric vehicle;
detecting the flow of current to a battery charger of the electric vehicle;
obtaining a VIN of the electric vehicle from an OBDM of the electric vehicle;
transmitting the VIN and a “
power-on”
signal from the electric vehicle to the EVSE transceiver via RF;
automatically removing power from the EVSE to the electric vehicle;
transmitting the VIN and a “
power-off”
signal to the EVSE via RF;
processing the VIN and “
power-off”
signal at the EVSE to confirm the identity of the connected electric vehicle; and
reapplying power from the EVSE to the electric vehicle to charge the battery power supply.

Abstract
A system for identifying an electric vehicle connected to electric vehicle service equipment (EVSE) and which involves RF communication exploits the OBDM of the electric vehicle as well as the auto-CAM system. Power is applied from the EVSE to supply electric power and the flow of current to the battery charger is detected. The VIN and a power-on signal is then transmitted by RF to the EVSE transceiver. Power is removed from the EVSE to the electric vehicle. A VIN and a power-off signal is transmitted to the EVSE and processed to confirm the identity of the connected electric vehicle. Power is then re-applied to the EVSE to charge the battery power supply.

7. An identification system for identifying an electric vehicle connected to EVSE comprising:
-
an EVSE having a cable with a power connector and a pair of power lines and a pilot line, said EVSE further comprising a processor in communication with an RF transceiver and in communication with a contactor interposed across said power lines; and an electric vehicle having an inlet for connecting with said power lines and pilot line, and comprising an OBDM in communication with an auto-CAM device which communicates with an OBDM port and has an RF transceiver, a sensor for sensing current in a power line and communicating said sensed power to the auto-CAM device, said power lines connecting with a charger for an on-board power supply, and a controller controlling said charger and communicating with the OBDM, wherein said EVSE cable is connected to said electric vehicle inlet and a first RF communication is transmitted from said auto-CAM transceiver to said EVSE RF transceiver to identify the vehicle VIN and indicate that power is supplied to said charger, said processor communicates with said contactor to remove power from said power lines, and a VIN and a second RF communication is transmitted from said auto-CAM transceiver to said EVSE transceiver so that said processor activates said contactor to restore power to said charger for charging the battery supply of the electric vehicle. - View Dependent Claims (8, 9)
