EMEL

The extensive use of electromobility in metropolitan regions faces the same dilemma as electromobility in general: an expanded charging infrastructure is needed to stimulate greater use of electric vehicles and vice versa. On the one hand, this requires an interface between the charging point and the vehicle that is as uniform as possible and capable of handling different charging scenarios - extensive research, development and standardization activities have been carried out in this area, leading to market-ready product concepts. The other key factor is the integration of the charging point or charging infrastructure into sustainable energy systems, namely in the smart home, smart grid and smart factory sectors. In future, small energy producers want to use their electricity from volatile renewable energies for their own consumption for mobility purposes and also offer it on a market. The structural changes required for this must be designed from a technical and regulatory perspective. The aim of EMEL is to develop marketable system solutions based on the corresponding preliminary work for this area.

Research and standardization for the integration of charging infrastructures in smart home concepts (use of own electricity), in the smart grid (Vehicle2Grid) and in a smart factory (Industry 4.0) is well advanced, especially at the level of the execution system or the lower layer of the operator controller module (OCM), and is being integrated into products. The connection in the information layer (reflective operator in the OCM) via the Internet of Things (IoT) with its solutions, e.g. for billing or authentication, must also be added. The connection of planning, simulation and optimization services at the level of the target setting system (cognitive operator in the OCM) forms the basis of the energy management system. According to the National Platform for Electromobility (NPE), system integration across the levels and in the individual components is the most important driver for the market success of electromobility in the 2017-2020 phase.

The project described above will therefore define and develop the technical requirements for integrating modular charging points for electric mobility into a heterogeneous metropolitan energy generation and charging infrastructure.

In the course of the project described, a system solution for the integration of charging points and charging infrastructures into metropolitan energy management systems will be developed and implemented as a prototype. Three relevant scenarios are addressed:

■ Connection vehicle - charging point - smart home (including use of own electricity)

■ Connection vehicle - charging point - smart grid (including vehicle2grid)

■ Connection vehicle - charging point - smart factory (operational energy management)

In addition to the use of the corresponding interfaces and standards at the respective electricity grid level (e.g. smart meter), the use of the IoT with its solutions, e.g. in the area of authentication and payment, is also planned. The partitioning of functionality to the OCM levels and the connection with the IoT (e.g. in the Eclipse project RISE V2G) is the innovative core addressed by EMEL. The provision of interfaces for energy management services at the top level of the OCM makes the system intelligent.
