Abstract

 

eDAS is an acronym for efficiency powered by smart Design meaningful Architecture connected Systems. It's a specific targeted research project (STREP), funded by the European Union. eDAS is part of the ICT Green Cars 2013 theme for research and development, implementing the Seventh Framework Programme of the European Union for research, technological development and demonstration activities.

 

Holistic Energy Management for 3rd and 4th Generation of Electric Vehicles

 

Modern societies are eagerly looking for the integration of mobility into their urban living area and for reliable and safe electrical vehicle (EV) transportation, better efficiency and cost, comfort and low emissions for the environment. The trends are obvious, however, providing a hybrid/electrical car is only one part of the full picture. The “standard” customer is still very reluctant to buy a full electrical vehicle (FEV). The reasons are manifold but the most important is unpredictable mileage and limited autonomy. The prediction of the cruising range without any restrictions in terms of safety and comfort is a key point: essential is D-P-C (Drive safely, Park easily and Charge conveniently).

Today a nominal 100km range might vary from 50 to 130km in reality, depending on various conditions such as temperature and profile of the route. Increasing the capacity of the battery is no viable option because it results in a drastically increase in cost and weight of the car. Through eDAS we will limit the negative impact of high and low environment temperatures from -50% today to a maximum of -20% of the reachable range in electric vehicles, which corresponds to an improvement of 60% compared to state of the art. We will bring the subsystems of the EV to the optimum operating temperature range for faster “fast charging”, pre -conditioned passenger compartment and battery, also safety and convenience features, such as de-iced windows during winter time, based on the available subsystems without adding cost and weight. We will develop new designs and architectures combining battery, e-motor, electronics, charger and energy management.

Addressing this challenge of the architecture of all subsystems of the complete EV requires a wide area of expertise, and in consequence leads to a large consortium. For a list of all partners of eDAS, take a look on our partner's site. eDAS cooperates with the research projects iCompose and Incobat.
