• wherein the first processor is configured to:
• operate under a first communication protocol to communicate with said electric vehicle to obtain a vehicle ID and an initial state of charge of a vehicle connected to the plug;
• operate under a second communication protocol to communicate with said electric vehicle to advertise available current to said electric vehicle;
• measure vehicle power consumption data during charging of the electric vehicle;
• operate under a third communication protocol to transmit the vehicle ID and initial state of charge data to the charging station management system;
• and
• operate under the third communication protocol to transmit the vehicle power consumption data to the charging station management system, and
• wherein the second processor is configured to:
• obtain from the charging station the vehicle ID and initial state of charge data;
• and
