Roadway electrification with in-motion charging of
Electric Vehicles (EVs) represents a promising solution to support
the widespread adoption of EVs with reduced battery size and
cost. However, numerous design challenges are involved in the development
of the associated infrastructure, particularly for largescale
roadways with in-motion wireless charging. This paper
introduces a dc current distribution architecture and provides a
comparative analysis of dc current and voltage distribution architectures
for large-scale DWPT systems. Mathematical loss models
are provided and applied to evaluate power distribution system
efficiency as a function of traffic volumes and corresponding EV
loads on the roadway. A design for a 1 MW system supporting
up to 20 secondary pads with 50 kW power rating has been
used as a case study. The analysis shows that the efficiency of
dc current distribution systems increases as adoption progresses
with increased charging load on road segments.
