Outline of Final Research Achievements

In this research, while issuing a wake-up call to electric car development that proceeding at a lithium-ion battery full commitment, we proposed the "Another car society" based on "motor / capacitor / wireless", and developed about 10 key technologies during this three-year plan.
Specifically, we developed cars which are connected to power system infrastructure by "wireless power transfer", and are driven by frequent or conitunous charge to "capacitor" such as electric trains. By utilizing the largest advantages of the electric "motor" in the viewpoint of motion control, we realized a further energy saving and improvement of safety.
In the end of the study, taking advantage of the geographical advantage of the University of Tokyo Kashiwa Campus, social experiment of the regional transportation system was carried out.
