电动公交车等重型车辆的无线充电技术已得到积极研究，以加速部署一种重要的环保交通方式。我们一直在开发一种无线电力传输（WPT）系统，用于电动公交车的快速充电。大部分性能目标都实现了：接收的最大电功率为44 kW或更高，发射和接收充电垫的最大错位公差为+/-10 cm或更高，辐射发射减少到符合无线电法的限值。本文提出了一种低辐射发射的设计方法，并对WPT系统进行了评价。
Wireless charging technology for heavy-duty vehicles, such as electric buses, has been actively investigated with a view to accelerating deployment of an important form of eco-friendly transportation. We have been developing a wireless power transfer (WPT) system for rapid charging of electric buses. Most of the performance targets were achieved: the maximum electric power received was 44 kW or more, the maximum misalignment tolerance of the transmit and the receive charging pads was +/−10 cm or more, and the radiated emission was reduced to within the limits in accordance with the Radio Act. This paper presents a design method for low radiated emission, and the evaluation of the WPT system.
