Many EVs can charge 80% of their battery in a matter of minutes, but for some applications range anxiety and charge time are still a concern. One possible solution is an embedded electrical rail in the road like the [eRoadArlanda] that Sweden unveiled in 2016.

Overhead electrical wires like those used in trolleys have been around since the 1800s, and there have been some tests with inductive coils in the roadway, but the 2 km [eRoadArlanda] takes the concept of the slot car to the next level. The top of the rail is grounded while the live conductor is kept well underground beneath the two parallel slots. Power is only delivered when a vehicle passes over the rail with a retractable contactor, reducing danger for pedestrians, animals, and other vehicles.

One of the big advantages of this technology being in the road bed is that both passenger and commercial vehicles could use it unlike an overhead wire system that would require some seriously tall pantographs for your family car. Testing over several Swedish winters shows that the system can shed snow and ice as well as rain and other road debris.

Unfortunately, the project’s website has gone dark, and the project manager didn’t respond when we reached out for comment. If there are any readers in Sweden with an update, let us know in the comments!

We’ve covered both overhead wire and embedded inductive coil power systems here before if you’re interested in EV driving with (virtually) unlimited range.

Ford Motor Co. is working with Israeli startup Electreon to construct a mile-long road near Detroit’s Michigan Central Terminal that will charge electric vehicles as they travel on it.

The pilot program will deploy an inductive in-road charging system in partnership with the Michigan Department of Transportation, the Michigan Office of Future Mobility and Electrification and the Michigan Economic Development Corp.

“We are proud and thankful to be selected by the Michigan Department of Transportation to lead and implement the first wireless electric road system in the United States,” said Stefan Tongur, vice president of Electreon.

Electreon’s technology can wirelessly charge EVs whether they are moving or stationary. This project will be one of the first to be installed on public roads in the United States.

The company currently has pilot projects in Germany, Sweden and Italy. Recently it signed an agreement to develop a plug-free charging network for 200 transit buses in Tel Aviv.

Inductive charging has the potential to ease range anxiety for EVs owners and reduce their cost of charging at home or at public charging stations.

Everyone should be aware of our impact on the planet and our potential DOOM! I want everyone to switch to electric cars, and a virtually infinite range would interest the buyers. Let’s do it!

Stretch of road outside Stockholm transfers energy from two tracks of rail in the road, recharging the batteries of electric cars and trucks

About 2km (1.2 miles) of electric rail has been embedded in a public road near Stockholm, but the government’s roads agency has already drafted a national map for future expansion.

Energy is transferred from two tracks of rail in the road via a movable arm attached to the bottom of a vehicle. The design is not dissimilar to that of a Scalextric track, although should the vehicle overtake, the arm is automatically disconnected.

The electrified road is divided into 50m sections, with an individual section powered only when a vehicle is above it.

When a vehicle stops, the current is disconnected. The system is able to calculate the vehicle’s energy consumption, which enables electricity costs to be debited per vehicle and user.

At a cost of €1m per kilometre, the cost of electrification is said to be 50 times lower than that required to construct an urban tram line.

Säll said: “There is no electricity on the surface. There are two tracks, just like an outlet in the wall. Five or six centimetres down is where the electricity is. But if you flood the road with salt water then we have found that the electricity level at the surface is just one volt. You could walk on it barefoot.”

Sweden is paving the way for renewable energy after debuting the world’s first vehicle-charging electrified road

It works by recharging the electrical batteries of vehicles as they drive along the road, using a technology called conductive charging. According to project overseers eRoadArlanda, electricity is supplied via conductors embedded in the road.

The vehicle is connected to an electrified rail and, as long as the vehicle is above the rail, a movable arm transfers power from the rail to the vehicle’s battery.

“There is no electricity on the surface. There are two tracks, just like an outlet in the wall. Five or 6 centimeters [2 or 2.4 inches] down is where the electricity is,” eRoadArlanda chief executive Hans Säll told The Guardian. “But if you flood the road with salt water then we have found that the electricity level at the surface is just one volt. You could walk on it barefoot.”

While other nations are developing similar systems and technologies, Sweden’s announcement is the “first of its kind” to allow both commercial and passenger vehicles the opportunity to recharge while driving.

For now, 2 kilometers (1.2 miles) of electric rail have been installed outside of Stockholm.

Electric power giant ABB has developed a battery charging technology
The new charging technology is becoming deliveries. ABB has won a total value of more than 16 million US dollar orders for the Geneva public transport operator TPG

ABB will supply and install 13 fast charge status of the city bus route, as well as three and four terminal depot charging stations.

The buses batteries can be recharged in 15 seconds at the bus stop 600 kilowatts of charging current. Three to four minutes in a sustainable additional charge batteries can be completely filled.

A new charging technology has been developed in Switzerland.
