Progress beyond State of the Art

 

Standardization of the temperature levels of the different elements in the energy network will foster lower cost, higher efficient cooling solution and scalable systems and sub systems. The demonstrators will consider safety aspects and be evaluated with respect to robustness, by using fault injection methodologies.

eDAS will build an energy network within the FEV, making use of the available energy sources (electrical, thermal, mechanical), control them in an optimized way to feed energy back to the system and to minimize the impact of the external factors (temperature) by preconditioning of the car in order to achieve predictable and reliable mileage.

eDAS will provide solutions for predictable mileage exploring novel concepts such as using the combination of different also non electrical energy sources and storages in the FEV as a network of energy elements.

eDAS will also directly influence the battery efficiency by preconditioning of the car itself. Thermal conditioning will set for example the temperature of the battery to the best operating range for faster and thermal peak or overload free "Fast Charging" also protecting the battery by actively controlling State of Charge and State of Health. These aspects together will definitely minimize the uncertainty in range. For getting energy "en route" eDAS will provide novel concepts of direct interaction of the FEV with the available infrastructure in urban environments (Smart Grid) and by using the available navigation systems to plan the optimal topology for the route.

Finally, we will consider OEM’s requirements e.g. VW stated that the additional complexity and concepts for thermal managements must not add more than max. 20kg per 1000kg in weight to the car (class E-UP and class GOLF) and the cost need to be very closely monitored.
