In Italy the highway that recharges cars with asphalt

“Arena of the Future”: the electric mobility of the future tested at Brescia-Milan

Welcome to the mobility of the future. Recharge the engine of your car as long as you travel it is not a utopian dream, but a concrete and already ongoing project that may soon become a reality. Or rather that it is at least partly already a reality because experimentation with the new induction charging technology has already become something.
Along with other countries in the world also Italy, exactly alongA35 Brebemi motorway, between Brescia and Milan, has started the tests to verify the specific applicability. So it was created a special experimental circuitnot surprisingly called “The Arena of the Future”, How important information will be gathered in the coming months.

The Arena of the Future

The technology presented in Chiari, in the Brescia area, is called Dynamic wireless power transmissionsummarized in the acronym DWPT. It is a system using induction, it allows electric vehicles to recharge their batteries driving on special dedicated tracks.
Electricity is transferred directly to moving vehicles, whether cars, buses or lorries, through an innovative system with coils placed approx. 12 cm below the asphalt.

DWPT: power conversion and wireless

That Italian pilot project, coordinated by the A35 motorway management company Brebemi and by Aleatica, a global transport infrastructure operator specializing in sustainable and innovative mobility solutions, is currently in more advanced experimental stage.

the arena of the future
By utilizing the area it owns where there was an abandoned service area, Brebemi has actually created an experimental circuit to continue testing the new technology.
That Dynamic Wireless Power Transfer is connected to the electrical distribution network medium voltage in a photovoltaic system. From here, the current reaches a hut where it conversion of electricity from medium to low voltage and from alternating to direct.
Through the transition to a management unit comes the same flow then again converted from direct to alternating, but with a frequency of 86.5 kilohertz, suitable for wireless.

Transfer of energy to the induction machine

In fact, this is system by which electricity is transferred from the primary coilthe one who is put in the street, to the secondarypresent on vehicles.
To activate the coils, the same passage of the vehicles, which generates a magnetic field through which the charging takes place through a energy transfer by induction.
The receiver installed in the vehicle is thus able to use the received electricity either to drive the engine directly or by storing it in the battery.

Electric cars: the European innovations

The pilot project, which is part of the ecological transition path towards decarbonisation of transport, was presented just a few weeks before confirmarrived on the night between 28 and 29 June, by the Environment Council of the European Union al ban on the sale of new vehicles powered by internal combustion engines from 2035.By that date, the EU’s target is to achieve a total reduction of carbon dioxide emissions with an intermediate stage for assessing progress by 2026.
At the same time as opening up biofuels and other green engines, the agreement at the continental level clearly focuses primarily on electricity. Therefore, in this perspective, it will be important not to waste time on the infrastructure front.

Induction charging and decarbonization of transport

In the document “Decarbonising transport, scientific evidence and policy proposals”, recently presented by the experts involved by the Ministry, induction charging has been identified as one of the possible concrete solutions towards the targets set by the “Fit for 55” package, presented by the European Commission in implementing the Green Deal strategy.

And the tests already performed on DWPT technology have highlighted one of the benefits of induction charging greater energy efficiency of the vehicleone reduction of battery volume in vehicles without affecting the load-bearing capacity of goods and persons, a increase in average battery life itself thanks to the fact that charging tips would be avoided because it would get power at intervals during the day. In addition, when fully operational, the system will be able to do so reduce parking times for recharging.

The first data in the autumn: prospects already for 2023

To make these results possible, the most innovative technologies are offered by 5G and application solutions based onartificial intelligence. Not surprisingly, the project sees among the partners leaders in their respective sectors such as Abb, Electreon, Iveco, Iveco Bus, Mapei, Pizzarotti, Politecnico di Milano, Prysmian, Stellantis, Tim, Fiamm Energy Technology, Roma Tre University, Parma University. , Fire Brigade and Ministry of the Interior- Traffic Police.

That Next step for the Italian pilot project is set toautumn 2022, when they become evaluated the results collected in 3-4 months of experiments on the motorway section where the circuit was built.
L ‘objective it is then to be able to go to the beginning of the phase of a first concrete implementation of the zero-emission mobility system already in 2023. At the same time, we will also continue at the level of possible commercial development, in Italy and abroad, as it is one technology also suitable for infrastructures such as airports, ports or car parks. Not surprisingly, among the most recent expressions of interest is the one from Bergamo Airport in Orio al Serio, to experiment on its buses.
