To achieve a mass market acceptance of electric mobility, the development of personal safety mechanisms, authorization methods and asset management of charging infrastructure requires standardized ICT protocols. For all these issues protocols have been developed and a roll-out of Electric Vehicles (EV) is feasible. To increase the market penetration of e-mobility, EVs can take part in value added grid services (e-services), which can increase the grid stability in case of high fluctuation of renewable energy resources. As only a single EV charging process cannot compensate grid fluctuations, this paper presents a pooling strategy of multiple charge points, which are controlled by a central pool operator that can react upon grid congestion. Two of such e-services are discussed in this paper by developing an ICT architecture with standardized communication protocols. After an introduction of the used protocols, protocol interaction for realizing the e-services is illustrated by several sequence charts. Therefore a new e-service interface including message definition is developed. These messages are based on standardized message types of ISO/IEC 15118. This ensures interoperability and integration of e-service interface into ICT protocols for charge point management, e.g. Open Charge Point Protocol (OCPP).
