Research On Information Security Of Charging Station For Electric Vehicle

Electric vehicle charging station is an essential energy services infrastructure after electric vehicles become operational and commercial. In the commercial context, providers operate according to their own development model. So the equipment in the communication network has different specifications and protocols. So it is necessary to establish the management and operation system to manage all of the data and achieve information sharing. In addition, the security of information is also very important. The information security is the key to ensure the normal operation of charging stations and electric vehicles. It is the point of the construction of charging station communication network.This paper studies the charging station communication network, first introduces the communication network of electric vehicle charging and swapping station detailedly. And then it analyzes the communication network between charger and monitoring center inside station as well as charger and electric vehicle batteries management system. The information security requirement of communication network can be analyzed in terms of the security requirements of physical, network topological structure, system and applications, information interaction, CAN bus network and Ethernet network etc. And then the protection design of the communication network information security can be built according to the information security requirements of communication network. Finally it sums up the factors harming the information security of communication network, In addition the information security evaluation model is established in the way of analytic hierarchy process. And therefore the weight of factors can be calculated. And then the ratio graphics of each layer and the weight are draw up and the key factors affecting information security can be found, which provides an important theory evidence for the construction of charging station communications network.
