Abstract
Embedded coils into road pavement are applied to dynamic wireless power transfer (DWPT) that coil arrangement is different from static WPT system. Contamination easily enters the road pavement between the coils. Therefore, it is necessary to clarify the effect of contamination on the efficiency of DWPT. Coil parameters and theoretical efficiency have been evaluated by an LCR meter. Furthermore, WPT system efficiency has been evaluated by a power transmission experiment. Iron sand, which is the effective contamination in road construction, affects coil parameters causing a 0.14% reduction of maximum efficiency. Moreover, remained seawater and rainwater decrease the AC-to-AC efficiency by 0.93% and 0.6%, respectively. In addition, remained waters change the resonance frequency of the system.
