[Abstract]:As a green, environmentally friendly and economical vehicle, electric vehicle (EV) is developing rapidly. The electric vehicle charging facility is the important foundation to ensure the operation of electric vehicle, and also the key point of the construction and development of smart grid. Nowadays, the traditional non-interactive charging method can not meet the need of intelligent charging. In order to achieve the purpose of intelligent charging management of electric vehicles, it is necessary to establish a high-speed and reliable communication connection between electric vehicles and charging stations (piles). The ability to communicate information between the power grid and electric vehicles. Power line carrier communication (PLC) technology makes use of the existing power lines to transmit information, which realizes the integration of power supply and information communication, and has unique advantages. On the other hand, the rapid development of PLC technology also makes it capable of this role. At present, the research and application of PLC technology in the electric vehicle internal control system or in the external charging control system are still in the initial stage, and are gradually becoming the research hotspot in foreign countries, especially in European countries. However, in China, the research in this area is still in the stage of exploration. Based on the construction of electric vehicle charging and switching power station system, this paper studies the system structure of electric vehicle charging and switching system, and analyzes the service communication requirements and information flow direction. This paper focuses on the communication service requirement between electric vehicle and charging pile, analyzes the service bandwidth and communication performance requirements combined with the communication protocol, and draws the conclusion that the application layer should have 10kbps transmission rate; In this paper, the application scheme of PLC technology between electric vehicle and charging pile is put forward, and the feasibility of narrow band and wide band PLC technology is studied. The applicability of several PLC products in the communication between electric vehicle and charging pile is tested and evaluated with laboratory test. The conclusion is drawn that PLC technology can fully meet the need of communication between electric vehicle and charging pile. In addition, by analyzing the background noise of charging cable channel, it is concluded that for narrowband PLC technology, using CP-PE line as carrier channel is better than using L-N line to transmit carrier signal. Finally, the paper analyzes the shortcomings of the current work and needs further research, and prospects for the application of PLC technology. This research will play a positive role in exploring the application direction of PLC technology, and will provide some guidance for the upgrading and improvement of PLC application technology.
