Abstract

Wireless charging technology for heavy-duty vehicles has been investigated for eco-friendly transportation. We present a new wireless power transfer system for 44 kW rapid charging of electric buses. Transmission distance between charging pads is from 10 to 13 cm. The large air gap can be fulfilled by the ordinary kneeling function equipped on most low-floor buses. Dual-block parallel transmission with opposite-phase-current-feeding suppresses magnetic radiation. The system operates in the common 85 kHz band with the light-duty vehicle system. The results of its field test and public road operation of two electric buses to confirm the effects of CO2 eduction and energy saving are described.
