Abstract

A novel conversion system has been developed for a medium size electric scooter. Particular attention has been paid to batteries size optimization, to minimize drawbacks on scooter weight for given autonomy, analogous to that of a combustion engine competitor. High-performance power conversion structures and management strategies have been adopted according to, and full exploitation of high-energy density Li-Ion cells has been reached. Safety and mobility guarantee against eventual cells collapse have been faced both in terms of mechanical bounding and fault by-pass. Plug-in PFC battery charge make the proposed conversion system a completely standalone solution for light EV traction.
