The strong and long-lasting external dependence and massive consumption of fossil fuels, particularly in mobility, represent the largest risk and challenge to reach an energy resilient Europe. However, Europe is committed to a green energy transition, e.g. increasing the use of sustainable energy sources, and reducing the various types of emissions. In response, the Energy ECS project develops a set of technologies in Electronics, Components and Systems (ECS), to accelerate the digitalization of e-mobility systems. The overall objective of the project is to enable new European know-how and manufacturing capabilities of hardware, software, services and data for e-mobility solutions. The project builds on six use cases, showcasing advanced energy and mobility solutions of the future: enablers of new logistics modes, energy independent intermodal transport, charging technologies and opportunities, grid stability responding to bi-directional charging, and strengthens foundation of safe autonomous driving. Therefore, the Energy ECS project aims to facilitate the emergence of new business models and ecosystems, enabled by the restructuring of technology and business value chains that energy and mobility sectors are currently facing.
