E V R E S TElectric Vehicle with Range Extender as a Sustainable Technology
The EVREST project is a transnational European Project carried out in the framework of the ERA-NET Electromobility+ call.
Why Electric Vehicles with a Range Extender
An electric car with a small combustion engine or fuel cell that charges the battery on the move.
Electric Driving
The vehicle is driven by an electric motor, which supports the goal of cleaner urban mobility.
Extended Autonomy
The range extender adds autonomy so that the driver is not restricted to short trips between charging points.
Sustainable Use
The project examines the environmental effects of the solution, including emissions and life cycle impacts.

The EVREST Project
Three European countries are involved: France, Germany and Austria.
The main idea of this project is to study how Electric Vehicles (EV) with a Range Extender (RE) could match the different usage patterns and what would be the impact of such a solution. Electric vehicles with RE would not be limited to urban trips. Occasional long distance trips would be possible and people living in low density areas could also be concerned.
Technical, environmental, and social assessments will be done and will lead to a Sustainable Development Analysis.
Follow the Project Results
The project publishes its work in stages, from the first survey to the final results. Each stage builds on the previous one, so readers can follow how the findings on range, charging and emissions were reached.
Survey results, deliverables and dissemination material are available through the pages linked below. They give a clear route into the research for both specialists and general readers.
Sustainable Development Analysis
The social assessment looks at how different socio-economic groups perceive the vehicle, what they need from it, and which charging facilities they would use. User preferences and perspectives shape the final conclusions.
All the technical, environmental and social findings are brought together in a Sustainable Development Analysis. This analysis is the main outcome that the project offers to decision makers.
Technical and Environmental Assessments
The technical assessment looks at battery size, range extender performance and fuel consumption across different driving situations. These results show how the vehicle behaves on short urban trips and on longer journeys.
The environmental assessment covers emissions and the life cycle of the vehicle, including the electricity generation and electric grids that supply the charging points. Together, these studies give a complete view of the solution.

Matching Real Usage Patterns
The EVREST study looks at how different drivers use their cars. Daily commuting, city errands and occasional holiday journeys all place different demands on a vehicle. By comparing these patterns, the project checks whether an electric vehicle with a range extender can cover them without forcing drivers to change their habits.
People living in low density areas often depend on the car for every trip. The project considers whether a range extender could give these users the flexibility they need while still reducing fuel consumption and local emissions.
