In last decades software development processes changed in order to address increasing complexity within decreasing implementation time. Hence, new practices like Kanban, Extreme Programming or Agile Software Development emerged. Model-based development is one potential option, which is more and more used to cope these new demands. However, adapting testing processes to the needs is still an open topic...
A major goal for the ISO/IEC15118 standard for controlling the charging process for electric vehicles is the simplicity and reliability of use. Severe threats for a simple use are implementations of the standard which are not interoperable to each other. A traditional approach to reduce this threat is the setup of testivals between all implementations to explicit test interoperability. However this...
A future widespread use of electric vehicles requires the deployment of reliable and comprehensive battery charging infrastructures. The communication between all systems, which are involved in order to control the battery charging processes or enable flexible billing of charging operations, becomes an important factor in acceptance of electric mobility. It will be a highly distributed infrastructure...
Electric mobility becomes very important due to a lack of fossil fuels in the future. Hence, it is obvious to replace conventional vehicles with gasoline or diesel engines with Electric Vehicles (EVs). An important area of such replacements are vehicle fleets of companies or urban administrations. The goal of the research project metropol-E is to develop a concept for integrating Electric Mobility...
For charging Electric Vehicles (EV) a communication between the EV and the Electric Vehicle Supply Equipment (EVSE) is inevitable. The Low Level Communication (LLC) protocol IEC 61851–1 is based on a Pulse Width Modulation (PWM) and provides safety to the customers by detecting errors very fast, e.g if the EV is disconnected from the EVSE. High Level Communication (HLC) Protocols are needed for authentication,...
The adoption of standardized Web Service communication protocols from manufacturing and automation industries carries a number of currently unused potentials for energy distribution processes. This work addresses potential advantages of such an approach, particularly highlighting benefits for medium-term, wide-spread use of Distributed Energy Resources (DER). Therefore a new communication protocol...
