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

Design, implementation and experimental results of an inductive power transfer system for electric bicycle wireless charging

“…In future development, a ferromagnetic core could be inserted at least on the grid side. The data obtained from the experimental analyses shown in [17] and from the finite element magnetostatic simulations were the starting points for the coil design.…”

“…In [11, 12], different strategies for optimisation of the size and shape of the magnetic couplers used in IPT‐based EV battery charging are proposed. In [13–20], the most significant IPT technologies for EV charging are discussed; in [21], different inductive coupling solutions are thoroughly compared in terms of tolerance to misalignments and efficiency; in [22], a single controller is proposed for the regulation of an IPT system, whereas in [23], a modular IPT system is described. In [24], the misalignment tolerance of an IPT system is improved using the third coil.…”

Design and Realization of a Bidirectional Full Bridge Converter with Improved Modulation Strategies

“…Due to the potentially high voltage range of a stack of supercapacitors, proper DC-DC converter architectures could be used-in References [18][19][20][21] high-voltage-ratio topologies are described, feasible for several applications such as automotive, DC microgrids and renewable energy sources. At the same time, such high voltage levels could suggest the use of galvanic isolation in order to guarantee safety-in References [22][23][24][25][26][27] different applications of isolated DC-DC converters for energy storage management are reported.…”

Approach to Choose of Optimal Number of Turns in Planar Spiral Coils for Systems of Wireless Power Transmission

“…Let us consider several solutions in this field. The authors in [16] presented a WPT system for electric bicycles with power of 100 W. Bearing on the required value of mutual inductance, optimization of turn number was performed, and the value of 9 turns was chosen for both receiving and transmitting coils. When selecting the number of turns, the authors also considered the requirements that the coil must be lightweight, compact, and cheap.…”
