electric car charging road

Mission Is A Green Life

By 2030, Sweden is planning to end fossil fuels usage all around the nation, one part of this project, of course, switching to electrified transportation and leaving usage of conventional engines by constructing EV-charging roads.

As the responsible company stated, now it costs $1.2 million per km (0.62 miles) to embed the stripe and slots to the road to electrify, which is rather expensive. However, as the company claims, it’s 50 times cheaper than constructing and managing tram line in the city. On the other hand, another advantage of the slot over cable is, of course, it’s looking more modern and tidied than all-around wired roads while charging electric cars.

Though its still a concept, Sweden has operationalized world’s first EV-charging road for about 1.2 miles length.

The aim is simply charging the electric vehicles on the move and by doing so decreasing the battery sizes, weights and total costs of electric vehicles, rather than setting up charging stations on parking lots.

Safety

The system is called as ‘dynamic charging’ which is embedded in the road as 50m (54.6 yards) divided sections. Every single individual section is powered at the time when the vehicle is on it. On the other hand, when the vehicle stops, the current is disconnected as well. The visible part is only the two parallel tracks on the surface, and the current is about 2-2.5 inches deep in the slot. You could walk on your barefoot on it as even you cover the surface with salt water, the current is only 1 volt on the surface.

Verdict:

The point I’d like to criticize here is the system is dependent on a connection to a single track and friction.

The first problem here is, auto manufacturers will need to design cars with these arms and If other countries don’t apply the same road systems to their own roads, the market will be too narrow to develop and produce those cars as the demand will be less than enough.

Even if you can solve the isolation problem during a rainy weather, what will happen on snowy or icy winter days? will the poles attach to the socket as they supposed to be?

Another point is, will those charging arms affect the aerodynamic build of the car? will they be added to the only small city cars and trucks? or will we see them under the high-end luxury and sports cars like Porsche, Tesla, and others?

Psychologically will everyone be willing to be in a vehicle similar to the slot car toys they used to play in their childhood? After all who would want to be dependent on driving on a straight line?

On the other hand, as it works with friction, will the system obliged to work under limited speeds? will you have the chance to drive over 60 mph in case of an emergency? How durable will the arms be to the friction before wearing out and need to be replaced?
