 Obiettivo del progetto (Objective)

'Following the Green Car Initiative (GCI) included in the European Economic Recovery Plan there is a high demand for electrification of transport in Europe. There are currently several concepts for FEV (fully electric vehicle) and HEV (hybrid electric vehicle) that support this “electro mobility” demand. The development and improvement of the different concepts require a huge effort in analysis, design, implementation and testing and not to forget feeding back experience, results and knowledge to new generations of Electric Vehicles. Advanced modelling tools and testing procedures going from one-dimension to three dimensional approaches have a fundamental role to play in optimizing during the earliest project phases for the energy dimensioning of FEV & HEV as well as their “energy management strategies” while reducing project’s development lead-time as well as to build-up requirements for subsystems and their related control units. Research in this project will focus on the development and validation of numerical simulation tools, virtual prototyping and advanced physical testing procedures and on the standardization of such tools in order to: • Investigate solutions for improving the efficiency and performance of future generation EV and their constituent components and sub-systems that may be critical from the energy efficiency point of view. The development of these sub-systems is however excluded. • Assess the effect of different sub-systems solutions in terms of energy efficiency and related increase of autonomy on different specific real life driving cycles that will take into account traffic constraints, road slope evolution, etc. • Verify technological feasibility and economic viability of the advanced solutions proposed.

ASTERICS project aim is to develop advanced modelling and testing tools and methods that will be the base for future developments of FEV & HEV trough all Europe, contributing to the competitiveness in this sector, in all its aspects.'

Introduzione (Teaser)

Electric vehicles (EVs) promise the greatest reduction in carbon dioxide (CO2) emissions of any other technology in the road transport sector. A comprehensive simulation and testing suite will make sure potential is realised quickly.

Descrizione progetto (Article)

The EU and G8 leaders agreed in 2009 that CO2 emissions must be cut by 80 % by 2050 for global warming to stay below pre-determined 'safe' levels. This challenging overall reduction may require 95 % decarbonisation by the road transport sector. It is unlikely that improvements to conventional internal combustion engines in combination with the use of biofuels will be able to meet these targets.

EVs are the most promising technology to do so. However, rapid development and improvement of current concepts requires advanced modelling and testing tools. The EU-funded http://www.asterics-project.eu/ (ASTERICS) project is meeting this need with a simulation tool suite and testing procedures.

The technologies are expected to play a fundamental role in optimising energy dimensioning and energy management strategies in the earliest design phases. The target is increased efficiency and performance of EVs by at least 20 %. The tools will simultaneously enable a 50 % reduction in overall development time and testing efforts for EVs and components.

Work in the first period emphasised a model-based system engineering process and an overview of available modelling and testing environments as well as realistic driving cycles for EVs. Further research focused on the definition of use cases spanning the entire development life cycle of EVs.

Fundamental to the initial phase of work was a comprehensive analysis of EV-specific driving cycles, including extensive test runs of EVs in real environments. The research culminated in delivery of a driving cycle calculation tool. This enabled scientists to begin definition of specifications and requirements for accelerated testing of powertrain components as well as for integrated powertrain systems.

The ASTERICS team has set up the project website from which interested stakeholders can download all related articles, newsletters, leaflets, videos and other documents. In the end, the simulation and testing tools are expected to make a major contribution to the optimised design of EVs. Taking into account both the unique powertrain and use requirements of EVs, the tools should lead to high quality, reliable and energy-efficient EVs in half the development time currently required.
