Abstract:

The distribution of the small electric vehicles called personal mobility devices (PMDs), which can address problems such as traffic issues and environmental pollution, is expected to gain momentum.  The present study proposes a new charging system that can respond to the needs of PMDs having various voltages and implement low charging current ripple. Therefore, the multi-level charging system proposed in this paper is expected to contribute to the commercialization and distribution of small electric vehicles by increasing the availability of charging options.  In order to verify the validity of the proposed charging system, the authors performed simulations and conducted experiments by building a prototype charging system.
