A system that will revolutionize the charging of electric cars and prevent stopping during the journey

Did you know that technology already exists that could revolutionize electric car charging and avoid the need to stop on a long journey? This solution has been in the testing phase for years and would be a key impetus for the electrification of ground transport.

We agree that one of the main Achilles heels electric car they are battery charging times. To this we must add autonomy that this type of vehicle offers, which requires you to carefully plan a long journey before you start driving.

This is true for a car with an internal combustion engine, in which the filling of the petrol tank or diesel It won’t take you more than 5 minutes, in the electric car you will have to make several stops on the trip, at least at fast chargers where you can recharge a sufficient percentage of the battery to continue the route to the destination (or the next charging point).

Of course, that’s quite a handicap when it comes down to it electrify land transportThis is Heavy vehicles transport of goods (trucks) or passengers (buses). These types of vehicles are designed to travel long distances in 8-hour shifts, although the trucks usually change drivers so they don’t have to stop.

A system that will revolutionize the charging of electric cars and prevent stopping during the journey

Fortunately, it already exists a system that will revolutionize electric car charging and prevent you from having to stop on the way to connect to a charging point. This technology, which is in the testing phase in certain parts of Europe, will also accelerate the electrification of heavy vehicles.

We are talking about the so-called electric road. These are sections (or complete roads) where it is possible to charge the battery of an electric car while driving. There are three possible technologies to achieve this goal study and develop:

  • Chain lines: designed for heavy vehicles, it is a system that uses overhead cables or cables integrated into the asphalt to supply electricity to trucks and buses equipped with mechanical arms on the roof or bottom to come into contact with the trolleys. It is basically the method used to run city trams or Renfe trains like the AVE.
  • conductive charge: Vehicles are equipped with a charging pad like smartphones. It comes into contact with the road when the vehicle is on it and allows the battery to be charged without the need for cables.
  • Inductive charging: A special set of copper coils placed under the road creates a magnetic field when an electric current passes through it. A coil installed in a vehicle receives electricity through induction, which can power the car and charge the battery while driving.

Of all these technologies, charging batteries on the go is Inductive charging seems to have the best chance of becoming a reality on the highways of the future.

Moreover, the goal is not to equip all roads in the country, but rather those strategic sections where the movement of cargo is most needed, such as highways that connect large cities.

Projects tested in several countries and a promising study

This is not the first time that this road technology with moving cargo has been talked about. We knew in the past tests in Sweden and Germany, or the test track that Stellantis has Italy from 2021.

From the tests carried out in Sweden, experts extracted some conclusions interesting ones that indicate where this technology will go in the coming years.

The idea would be, as I mentioned two paragraphs above, electrify 25% of the country’s roadswhich makes it easier to equip vehicles with batteries with a lower energy capacity, which in turn favors weight and consumption savings, increases autonomy per kW consumed, lowers the price of electric cars and shortens charging time.

The aim would be to combine home charging with on-the-go charging, which these experts say would make it possible reduce the size of electric vehicle batteries by up to 70%.

In addition, drivers who live in large urban centers could drive cars with lower energy capacity batteries, while those who live in rural or more remote areas would have electric cars with higher capacity batteries. The study estimates that the difference between them will be 20%.

What will happen with it remains to be seen electric roads in the futurebut it’s an interesting solution that could end both EV range concerns and the two main weaknesses these types of vehicles have, while providing a key boost to the electrification of the road transport sector.
