Rechargeable electric vehicles are receiving increasing attention from customers as gas prices are constantly rising, from car manufacturers to address customer, market, and environmental demands, and also from energy utilities for integrating them into smart electric grids. While in the first step the emphasis is placed on electric vehicles as energy consumers, using their battery for storing energy and feeding it back to the energy network will be the consequent next step. Thus the electric vehicle will participate as a mobile energy node within the smart grid, having besides the electrical connection also data communication interfaces for charging control, information exchange, and for billing. The focus of this paper has been the interface between security for the interface between the electric vehicle and the charging spot. Nevertheless, the charging spot needs to be connected to the electricity grid, requiring further communication for the integration into the Smart Grid. One standard, which can be directly applied for the energy automation communication is IEC 61850, already applied in substation automation. This communication can be protected by security measures according to IEC62351. Moreover besides pure charging control relevant communication, there may be also value-added services provided through the charging spot like multimedia services, software or firmware updates, remote diagnosis, and so on. All of these services have to be protected appropriately. The intrinsic complexity of this overall Smart Grid vehicle charging system requires a systematic approach to include required security measures right from the beginning that can be used and managed efficiently.
