The research project fitted into a theme of great relevance for road vehicles with electric or hybrid propulsion. The interest for these innovative solutions came from the aim to meet different peculiarities depending on the type of vehicle and range of use:
- a) Vehicles with short driving range - a totally electric engine is adequate with benefits in terms of noise, emissions (zero emission vehicles) and reduced energy consumption costs.
- b) Vehicles with long driving range- a propulsion of the hybrid type is more adequate, since it combines a system with an internal combustion engine with an electric motor-generator, for an even greater autonomy than that of a conventional vehicle.
The result is a vehicle with low fuel consumption, good dynamic performance, with the possibility of purely electric operation for short sections.
The research project had the following objectives:
- Development of criteria and methods for the examination of different solutions for electric-powered vehicle according to their intended use and performance requirements, also in reference to the relationship of "hybrid" that is, the ratio between electrical power for propulsion and fully installed power propulsion.
- Definition of the criteria for choosing the optimal solution and the specifications for its constituent components (motor, battery, power electronics, etc.)
- Specification of some application examples with reference to conduct the study, the design and the testing of the most appropriate electrical structure of traction
- Development of criteria and procedures for the design of the main electromechanical and electronic components and the control, management and monitoring board systems.
- Measurements and testing of components and vehicles with the support, made necessary by the reduction of industrial co-financing, of industrial partners.
- Dissemination of results in scientific and industrial contexts for discussion and confirmation of their validity and for the product transfer for the market. This was enabled by the publication of a final report and the organization of a workshop in an industrial environment.
These are the results achieved by the different research units involved in the project:
- The feasibility study of a hybrid motorcycle was a first result of research interest.
- A comparative analysis of synchronous motors with permanent magnets inside
- The vehicle testing promoted a more effective dissemination of results beyond experts, to inform a wider public to the potential use of these vehicles.
- The scope of the proposed research consisted in the development and optimization of a passenger transport vehicle for private use towards an innovative urban mobility.
