Abstract:
Rechargeable electric vehicles are receiving increasing attention from different stakeholders: from customers as gas prices are constantly rising, from car manufacturers to address customer, market, and environmental demands, and also from electric 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. Batteries of electric vehicles will realize a distributed energy electric storage for stabilizing the electric power grid. Thus the electric vehicle will participate as a mobile energy node within the smart grid having two types of interfaces, one for electricity and one for data communication for charging and feedback control, information exchange, and for billing. Since IT security in the smart grid is already considered as a major point to be addressed, the enhancement of the smart grid with electric mobility has to address IT security as well. This article describes example interactions of electric vehicles with the charging infrastructure and it shows which security requirements have to be fulfilled in important use cases. Moreover, security considerations of current standardization activities in ISO/IEC and SAE are described.
