Design of a Wireless Charging System for Pure Electric City Buses
LU Fei,LEI Chao,WANG Ailin
Abstract: Aiming a 12m pure electric low-floor urban buses,this paper designs a highly efficient and secure wireless charging system.Through experimental verification,the optimal charging distance for the wire-less charging receiver is 225 mm from the ground.Mean while,a 3 mm non-magnetic aluminum plate serves as the metal shielding layer,which not only ensures charging efficiency but also meets the human protection requirement of the International Commission on Radiological Protection(ICRP).Additionally,this paper designs a wireless charging controller,which can precisely control and monitor the charging process in real time.The system ultimately achieves functions including static charging,dynamic charging,and remote wake-up from hibernation.
Key words: pure electric city bus; wireless charging system; charging emitter; charging receiver; charging controller
