Abstract

Electrical vehicles have to be periodically recharged. Currently, they are plugged to power station by cables. Wireless Power Transfer (WPT) Systems could be used instead of traditional cable connection to charge the batteries of electric vehicles. These systems are based on a couple of coils, one on the vehicle bottom and one under the road connected to a power station. Nevertheless, these systems are affected by the magnetic characteristic of the coupling coils, so that these devices should be carefully designed. In this paper, a pair of faced pancake coils equipped with ferrite core is considered. The possible geometries of the coils are designed using genetic optimization algorithms searching for optimal mutual inductance and saving in copper. This paper presents the analysis of the Pareto solutions obtained using automatic design strategy.
