A magnetized concrete highway to charge electric vehicles in motion

Although the eventual massive arrival of electric cars to cities responds to a future projection, the adaptation of urban spaces to this scenario is a topic of current interest.

In Indiana, United States, an initiative was presented to add a wireless charging infrastructure to its roads.

Magnetized concrete slabs that can charge electric cars driving overhead

The Indiana Department of Transportation and Purdue University, a university in the same state, through a joint effort joined the ASPIRE initiative, an acronym for Advancing Sustainability through Power Infrastructure for Road Electrification. energy for road electrification).

With public and private financing, this project began to be executed with the German company Magment, creators of the magment technology (same name, but with a lower case), which consists of a concrete magnetized with recycled ferrite particles, one of the crystalline structures of iron. With the first tests, it will be verified if the Magment product is capable of charging vehicles in motion at more than 200 kilowatts.

According to Magment, its product has a wireless transmission efficiency of up to 95% effectiveness, allows universal charging, has a vandal protection system, adapts to different climatic conditions and its implementation does not exceed the standard costs associated with construction. of roads.

In its most experimental phase, the research team behind this project will carry out tests, analyzes and optimizations in a laboratory. These tests are expected to begin before the end of the current quarter.

Next, if the first tests are successful, the Indiana Department of Transportation will build a quarter-mile stretch of this technology, in an undisclosed area, for actual testing. After evaluating this deployment, if the tests are successful, the construction of another section on a public road is planned.

Apart from aligning itself with a technology on the rise, revitalizing an experiment that has been tried to be carried out for years through different mechanisms, this initiative is also emerging as a solution for sustainability with the environment. “The field of transport is in the midst of a transformation not experienced since the invention of the automobile”said Nadia Gkritza, professor of Civil Engineering and Agricultural and Biological Engineering and Director of the ASPIRE Campus at Purdue University. “Through this research, we envision opportunities to reduce emissions and near-road exposure to pollutants, along with other automation and shared mobility transportation innovations that will shape data-driven policies that drive breakthroughs,” the researcher points out in the statements that a release published by the State of Indiana.
