Electric vehicle wireless charging, as an alternative to the conventional wired charging, is a hot research topic in recent years. Without a charging cable, electric vehicles can be continuously charged while driving, namely dynamic wireless charging. A common type of the dynamic wireless charging transmitter is a series of individual transmitting coils arranging along the charging route, which is called the segmented dynamic wireless charging. In this structure, the distance between adjacent transmitting coils is important in the system design due to its impact on the system cost and performance. In this paper, simulation analysis is carried out to evaluate the impact of the distance between adjacent transmitting coils. Using the parameters of an existing dynamic wireless charging system as a baseline, the influence of different distances between adjacent transmitting coils on the total mutual inductance and transferred power pulsation is demonstrated. These results are expected to provide the equivalent cost to evaluate the optimal distance between the adjacent transmitting coils, and some suggestions on the coefficients of the equation are also proposed.
