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
