“…The small slope is due to the internal resistances of the elements of the transformer. A more exact formula taking into account the resistances of the coils is presented in [4]. Finally, the efficiency of the transformer itself is presented in Fig.…”

“…Usually, a battery load cycle can be divided in two steps; the first one is performed at constant current while the second one is made at constant voltage. A solution consisting in combining two different compensation topologies in order to generate a battery load profile has been proposed [4]. However, the battery is also often charged with a constant current for fast charging purpose [5,6].…”

Contactless power transfer using inductive coupling is a well-known way to transfer energy from a transmitter to a receiver without any physical link. The applications are multiple. In this paper, the design and control of such a system for a contactless battery charger is investigated. The behaviour of the battery turns the system into a non-linear one. A solution dealing with the compensation topologies which aims to simplify the control of the transformer without any additional power electronics is proposed.

“…Geometry, materials, degree of alignment between coils and their influence over the coupling efficiency are deeply investigated. In addition to the study of the power stage, a wide analysis of different control strategies is dealt with [9][10][11][12]. Differently from the case of car application, few prototypes of wireless battery charging are reported as far as small power transmission systems for EV are concerned [13][14].…”

Recently, the wireless power transfer has been increasingly employed. Particularly for the electric vehicles, the wireless solution is attractive for contactless battery charging, based on the Inductive Power Transfer (IPT). In this paper, a 150W prototype for IPT-based battery charging is presented and design criteria are reported. In addition to the power stage analysis, a proper control strategy is proposed. Simulation and experimental results are shown. The proposed control method aims at regulating the load current against variations in the magnetic coupling, so that the required amount of power can be supplied despite of unexpected decreases in the coupling efficiency

“…Academic and industrial research has been ever more focusing on dynamic wireless battery charging [5][6]. As far as the implementation of an IPT-based wireless charging system is concerned, several topologies have been proposed and compared to investigate in detail efficiency and controllability [7][8][9][10][11][12][13][14]. IPT also facilitates the opportunity of a Bi-Directional power transfer between the grid and the battery, useful in V2G (Vehicle-to-Grid) applications, where the battery is employed as a storage element for the grid.…”

Wireless charging techniques, based on Inductive Power Transfer (IPT), are attractive for Electric Vehicles (EV), due to benefits such as convenience and safety. An accurate valuation of the maximum achievable efficiency in an IPT system is extremely unlikely due to the high sensitivity to parasitic elements variations. Therefore, an �on site� procedure of power efficiency characterization is useful to get a precise description of the efficiency curve and obtain the actual maximum efficiency. In this paper, a power tracking algorithm aiming at efficiency maximization is proposed for a Wireless Charging system. The algorithm aims at finding the maximum power transfer efficiency with respect to two control variables
