system would eventually be a lessexpensive
way to charge a vehicle.
Delta Electronics has multiple
extreme fast-charger system patents
relating to power-conversion topology
and control. To reach production
readiness, the system would need
to undergo additional development,
system integration, and testing.
Regulatory certification also is required.
Charging On-the-Go
Then there's the ultimate time-saver:
charging without stopping at all. A
roadway-embedded wireless charging
network for EVs is coming to a stretch
of urban highway in Detroit, marking
a pilot-program first on a U.S. public
road. " Our electric vehicle receiver
units are modular and compatible with
passenger vehicles and with light-,
medium- and heavy-duty commercial
vehicles, " said Oren Ezer, CEO of
Electreon, based in Tel Aviv, Israel.
Michigan is expected to operate the
first electrified roadway in early 2025.
Electreon's patented wireless
in-road EV charging technology
already is in use in various European
demonstration projects, including a
0.7-mile (1.05 km) intercity toll road in
Italy and a 1-mi (1.65 km) public road

in Sweden. Sweden's policymakers
aim to have 1,243 miles (2,000 km)
of electrified roadway in operation by
2030. Detroit's electrified roadway
will be near Michigan Central, a
mobility-innovation district under
development by Ford Motor Co.
" The wireless charging infrastructure
will support a suite of use cases
involving various vehicle types,
including autonomous vehicles,
and it will support partners, like
Ford, " said Jim Buczkowski, the
company's Executive Director of
Research and Advance Engineering.
Cloud-Based System
Monitoring
The $1.9 million-plus Michigan project
involves one lane of public roadway for
a minimum of one mile (1.6 km). After
the existing road surface is removed,
rubber-coated copper coil segments
will be buried 3.15 inches (8 cm) under
a new road surface. " Non-electric
vehicles are able to use the roadway
as usual without any disruption, " said
Dr. Stefan Tongur, Electreon's VP.
The roadway's coil segments transmit
power to an EV undercarriage-mounted
receiver via magnetic resonance
induction as the EV moves or is parked
directly above the coils. A powermanagement
unit located either
underground or above-ground near
the roadside will transfer the energy
from the electric grid to the roadway's
copper-coil infrastructure. " Cloudbased
management software enables
live monitoring and provides smartcharging
insights, " Ezer explained.
Electreon's technology solution
has 19 patents covering various
proprietary aspects, including the
engineered system architecture
and the communication mechanism
between an EV fitted with a power
receiver and the embedded roadway
coils. " The intellectual property of
our vehicle receivers will be released
to OEMs for free, " Ezer promised.
Both the battery size and the number
of receivers connected to an EV influence
the charging time. " The driving speed
has a negligible effect on the charging
performance, " Ezer explained. He said to
date, Electreon has tested its receivers up
to a speed of 49.7 mph (80 kph). As an
example, if a commercial truck with five
receivers is traveling at 37 mph (60 kph),
37 miles (60 km) of electrified road is
needed to fully charge the battery. If the
vehicle is traveling at 12.4 mph (20 kph),
12.4 miles (20 km) of electrified road
are needed to fully charge the battery.
Larger vehicles can support multiple
Electreon receivers. For instance, Class
8 trucks can be fitted with up to seven
undercarriage receivers. Buses could
have three receivers, while passenger
vans might have two receivers. " The
number of receivers on an electric
vehicle depends on the use case, the
vehicle size, and the vehicle type, "
