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.

Roadway-embedded wireless charging
for electric vehicles 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
with 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.
" 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, " noted 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). As of
mid-May, the Michigan Dept. of
Transportation (MDOT) was doing a
feasibility study on electrifying a section
of Michigan Avenue and/or 14th
Street in Detroit's Corktown district.
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 power-management
unit located either underground
or above-ground near the roadside
will transfer the energy from the
electric grid to the roadway's coppercoil
infrastructure. " Cloud-based manof
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
An Electreon employee signs her name on an
in-road charging coil before road resurfacing is
completed in Gotland, Sweden. The Smartroad
Gotland project began operations in early
2020 as a pre-commercial demonstration of an
electrified roadway.
