Experimental test on a Contactless Power Transfer system

Abstract

Contactless Power Transfer (CPT) is an ever-growing technology in automotive market, due to the significant improvement brought by it to battery charging operation in terms of safety and comfort. CPT is based on inductive coupling between two coils, so that power cords can be avoided for vehicles battery charging and an important contribution towards a smarter mobility can arise. In this paper, a CPT prototype for E-bike is proposed. Magnetic design and power electronics system are described. Experimental results deriving from laboratory tests are presented and power efficiency of the system is addressed.
