The Application of PLC in the Electric Vehicle AC Charging Technology

Electric vehicle charging, since the uncertainty of the travel area, and the different load control of the charging infrastructure grid and the different rates over time, needs to face different charging devices and use different charging parameters. The situation is very complex, so electric vehicle needs to be adaptive control for various situations in the charging process. Aiming at the communication between electric vehicle and power grid, there is no relevant national standards promulgated. After comparing several possible communication modes, I choose to use the PLC communication, and SDP for charging device to automatically obtain and connections. Charging parameter passing through the communication between the electric vehicle and charging facilities, in order to realize the adaptive control of electric vehicle charging.
