我们以前报道过一个60 Hz无线电力传输（WPT）系统，这是一个使用公共频率的系统。在论文中报告的研究中，我们解决了几个问题，以便将该系统安装在小型电动汽车上。首先，一个加速的时域有限差分（FDTD）方法，使用图形处理单元，以解决计算时间的问题。接下来，从等效电路分析导出包括杂散负载损耗的传输效率（η）和功率（Pout）的理论方程。基于这些理论方程设计了一种新的设备，其中对于150 mm的传输距离，η = 70%，Pout = 451 W。最后，我们尝试对铅蓄电池进行无线充电。在电池充电期间，无线充电系统的整体效率保持在60%。
We previously reported a 60 Hz wireless power transmission (WPT) system, which is a system that uses the common utility frequency. In the study reported in paper, we solved several issues in order to install this system in a small electric vehicle. First, an accelerated finite difference time domain (FDTD) method using a graphics processing unit was developed to solve the issue of computation time. Next, theoretical equations for the transmission efficiency (η) and power (Pout) that include the stray load loss were derived from an equivalent circuit analysis. A new device was designed based on these theoretical equations, where by η = 70% and Pout = 451 W were achieved for a transmission distance of 150 mm. Finally, we attempted to wirelessly charge of a lead storage battery. The overall efficiency of the wireless charging system was maintained at 60% during battery charging.
