Abstract
The use of compensation networks increases the power transfer capability of inductive power transfer (IPT) systems in the battery charging process of electric vehicles (EVs). Among the proposed topologies, the Series-Series (SS) and the LCC networks are currently in widespread use in wireless battery chargers based on IPT systems. This paper focuses on the study of the behavior of both compensation topologies when they are detuned due to the tolerances of their components. To compare their performances, a Monte-Carlo analysis was carried out using Simulink and MATLAB. The tolerance values, assigned independently to each component, fall within a [ − 20 , 20] % range according to a normal distribution. Histograms and scatter plots were used for comparison purposes. The analysis reveals that the LCC network allows a tighter control over the currents that flow through the magnetic coupler coils. Moreover, it was found that the increments in those currents can be limited to some extent by selecting capacitors featuring low tolerance values in the LCC compensation. Nevertheless, the SS network remains an appropriate choice if size and cost are essential constraints in a given design.
Highlights
The increasing trend in greenhouse gas emissions elucidates the need for a transition to a decarbonized energy system
The variations in the currents, the power transferred, and the efficiency were evaluated for both topologies
The main characteristics of each compensation topology are first highlighted for the case of a fully tuned system through a mathematical analysis
Summary
The increasing trend in greenhouse gas emissions elucidates the need for a transition to a decarbonized energy system. In this scenario, electric vehicles (EVs) become a clear alternative for internal combustion engine automobiles. Some aspects concerning the battery pack, such as its charging process, need further investigation. The EV battery charging process was accomplished by means of conductive chargers. The need for a mechanical connection between the transmitter and the receiver increases the electrocution hazard. In these systems, the user needs to touch the transmitter connector
