Secure metering for electrical vehicles

This paper addresses the problem of secure data communication in the charging architectures for electrical vehicles. Within the paper the different charging architectures will be described and examined further. The aim is to transfer the charging process data (customer, vehicle, metering and billing information) securely to and from the energy supplier or system provider. The main scope of this paper is to identify the most suitable architecture and meter location to achieve a transparent balancing and end-to-end secure communication between the customer and the energy supplier or provider.
