Abstract

We previously reported a 60Hz 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 (P_out) 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 P_out =451W were achieved for a transmission distance of 150mm. 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.
