of kilometres an electric vehicle can travel on a single charge and the charging
itself are often among the most discussed disadvantages of switching to this
type of car.
average range of electric cars is around 400 kilometres on a single charge, and
some models from leading companies can go significantly longer. Charging time
largely depends on the charging point. A car can be charged in just 30 minutes,
or it can take up to half a day. In any case, it takes longer than filling a
diesel-and petrol-fuelled motor vehicle.
there is still much room for innovation and improvement in electric vehicles.
For example, some companies are developing a different type of battery that
could at least double the range. On the other hand, there might be a solution
that could almost completely eliminate both problems: charging and the distance
each vehicle can travel.
So-called electric roads have wireless electric vehicle charging infrastructure installed under the asphalt. This could allow electric vehicles to operate 24 hours a day with unlimited range. One of the leading companies in this field is Israel’s Electreon Wireless, which is developing technology that can be used to charge all electric vehicles, regardless of brand or type of battery.
electric road technology is based on magnetic resonance induction with copper
coils embedded under the surface of a roadway. Unique copper coils are
installed just below the road surface on motorways, bus stops, parking lots, or
at commercial depot centres. The coils are then covered with asphalt.
transfer energy to a receiver that can be mounted under any kind of electric vehicle,
such as trucks, vans, buses and cars.
way, three different charging methods are enabled. The first is dynamic
charging, which involves charging vehicles in motion along their daily routes.
It is especially suitable for trucks and buses that travel daily from one point
to another and back.
method is semi-dynamic charging, which means installing infrastructure where
vehicles are temporarily stopped. Examples are taxis waiting for passengers at
train stations and airports or vehicles waiting to enter logistics hubs and
ports. Such a system is also suitable for vehicles stopped at intersections at
the traffic lights.
charging is the wireless charging of vehicles in parking lots, bus stations or
loading docks. In short, everywhere where vehicles are usually parked for a
long time and possibly turned off.
classic charging, where we must connect the car to a charging point, wireless
charging has quite a few advantages, as users can avoid problems with
connectors that they could run into with so-called “plug-in”
systems can also lead to smaller car batteries, making them more sustainable,
cheaper, and lighter. In addition, space for passengers and luggage would

believe that will be the case, but perhaps only in 50 years’ time. Ultimately,
that is how we want to see vehicles being charged because it eliminates the
need for large batteries,” he explained. “Why? Because we have
limited resources. Because we don’t want to end up with billions of big
batteries, we can’t recycle. That’s not green. Wireless charging can do that:
it connects us to the grid, but without wires.”
In June of this year, Electreon successfully completed the last phase of the “Arena of the Future” project, as part of which they plan to build a road strip at Bergamo Airport near the Italian city of Milan. The electric road system would thus power buses and official vehicles at the airport, the statement said.
As part of
the project, they integrated their wireless technology to charge an IVECO bus
and a Fiat Nuova 500 passenger vehicle while driving. Before that, a one-kilometre-long
electrified road was tested in the nearby city of Brescia since November 2020.
Meticulous Research expects that the wireless charging market for electric vehicles will be worth 827 million USD globally by 2027. Most of this growth will be directed towards static wireless charging in parking garages and bus or truck stops.
Asia-Pacific region accounted for the largest wireless EV charging systems
market share in 2020, followed by Europe, North America, the Middle East and
Africa, and Latin America.
Europe is expected to record the highest annual growth rate in the period to
2027. The factors contributing to the high growth of the European market are
the increasing adoption of electric vehicles, implementation of numerous pilot
projects for wireless EV charging technology, and government initiatives for
testing the feasibility of wireless charging technology for electric vehicles.
in Europe, in 2020, Germany accounted for the largest share of the wireless
charging systems for the electric vehicles market. Meticulous Research
attributes the market growth mainly to the extensive government support and
expansion in charging infrastructure.
example, last year, the German government approved the eCharge project worth
1.9 million EUR for implementing wireless dynamic charging technology on the
roads of Braunschweig, Germany.
initiators are scientists from the Technical University of Braunschweig (Technische
Universität Braunschweig), collaborating with companies in automotive
production, road construction, and energy infrastructure sectors.
“When a new road is built or renewed, the coils are installed at a depth of approximately ten centimetres and covered with an asphalt layer so that they cannot be seen from the outside,” explained Prof. Michael Wistuba from the Institute for Roads at the TU. “Power cables lead out of the road at a distance of 1.65-metres… into a so-called management unit, i.e., a control cabinet, at intervals of approx. Ninety metres [on the kerbside]. These communicate with the vehicles via the coils and switch road sections on or off as required.”
project is successful, the plan is to build 25-kilometre electrified charging
corridors at intervals along German motorways so that it is possible to extend
the range by up to 20% in each section, the professor added.
On the Swedish island of Gotland, wireless charging was installed on a 1.6-kilometre stretch of road where all types of electric vehicles can be charged. “It’s invisible, so when you look at the road, you don’t see anything,” Petra Carlenarson, project manager on the SmartRoad project, explained.
is led by several organisations, headed by Electreon AB, a subsidiary of the
Israeli company Electreon. The project is one of four electric road projects
funded by the Swedish Transport Administration.
The idea of
wireless charging while driving is undoubtedly attractive and worthy of further
development and ideas. In principle, it can solve quite a few problems with
electric cars. However, the central question of whether the electricity that
powers electric vehicles is of “green” origin or not remains
