Wireless Power Transfer for Personal Mobility Devices

Sharing systems of personal mobility devices equipped with batteries have become popular forms of transportation because of its convenience. However, the premised manual charging process via wires cause inconvenience and also increases operation cost. We aim to build a low-cost urban infrastructure which can empower these sharing systems through designing easily deployable wireless charging systems.

電池を搭載したパーソナルモビリティのシェアリングシステムがその利便性から流行の兆しを見せている．しかし，有線による手動での充電の必要性がコストの増加や利便性の低下を招く要因となっている．そこで本研究では，磁界共振結合型の無線給電を用い，道路に後から設置することが可能な給電設備を設計することで，低コストでかつ利用者が電池残量を意識する必要がなくなるような都市インフラを構築する．
