SS and LCC–LCC in Simultaneous Wireless Power and Data Transfer: A Comparative Analysis for SAE J2954-Compliant EVs Casaucao-Tenllado, Inmaculada Triviño-Cabrera, Alicia Corti, Fabio Reatti, Alberto Transferencia de energía Simultaneous wireless power and data transfer (SWPDT) is a technology that enables the transfer of electrical power and data signals at the same time. Since the transfer is performed through the same physical link, particular attention must be placed on the frequency response and mutual influence between data and power channels. Although several studies have been proposed for SWPDT modeling applied to electric vehicles (EV), an extensive analysis of the influence of misalignment on the frequency response of the data channels is lacking in the literature. This article investigates the robustness to misalignment of the data channel using two main resonant topologies, such as those based on series–series (SS) and LCC–LCC compensation circuits. The analytical model of the data channel is derived for both topologies and the performances are evaluated in two lab prototypes using the misalignment scenarios described in the SAE J2954 standard. Variables, such as efficiency, signal-to-noise ratio (SNR), and capacity of the data channel have been analyzed. Similarly, attention has been paid to backward data transmission, which is of interest for vehicle-to-grid chargers. The obtained results in each analysis show that the data channel in LCC–LCC topology has a more stable and symmetrical performance 2024-07-17T07:56:09Z 2024-07-17T07:56:09Z 2024-06 journal article I.
