e-DASH

The e-DASH project aims at the harmonization of electricity demand in Smart Grids for sustainable integration of electric vehicles. This is addressed by an intelligent charging system supported with real-time exchange of charge related data between EVs and the grid. Adopting the e-DASH approach allows high current fast-charging for large numbers of EVs in a brand-independent way and price-adaptive charging/reverse-charging at optimum price for the customer leading to increased desirability of EVs. In order to prevent damages of costly EV batteries, sophisticated charge control is inevitable. Moreover e-DASH also focuses on real-time grid balancing for unpredictable demand/supply situations according to spatially and temporally changing energy requirements (e.g. temporally connected EVs and regenerative energy sources). These objectives are enabled by the development of a V2G (Vehicle-to-Grid) front-end covering FEV Charging (V2G) and FEV Support (V2OEM Back-End Interface). Furthermore, the project addresses an E-Mobility Hub for authentication and billing and the development of an OEM Back-End for enabling V2G Brokering. Together with the Demand Clearing House and the respective EV demand & supply management, the e-DASH proposal targets intelligent infrastructure harmonization and delivers unique and innovative selling propositions for new V2G businesses and services. The technological developments are surrounded by cross-cutting activities like contributions to the ISO/IEC standardization and system integration and validation.
