As the EU passed a landmark law last month requiring all new cars sold to have zero CO2 emissions from 2035, European countries are rushing to prepare the infrastructure needed for fossil fuel-free mobility.

Sweden is turning the highway into an electrified road where cars, trucks and buses get dynamically charged while on the move. This is the first such road in the world to be converted into an e-highway.

Dynamic charging will allow EV's to travel longer distances with smaller batteries, and to avoid waiting at charging stations.

"We think the electrification solution is the way forward for decarbonising the transport sector and we are working with a number of solutions," Jan Pettersson, Director of Strategic Development at Trafikverket, the Swedish transport administration, told Euronews Next.

The proposed e-highway is the European route E20, that connects logistic hubs between Hallsberg and Örebro, located in the middle of the country’s three major cities, Stockholm, Gothenburg, and Malmö.

The news link also states that the charging method for E20 hasn’t been decided, but there are three types of charging: catenary system, inductive system, and conductive system.

The project is slated for completion by 2025.

How efficient are these? When it comes to wireless charging, there's a lot of loss of power, but that's smaller scale. Here it'll be much larger I presume? Is faster charging not the better solution although yes, it's physics and there are limitations there?

The idea is being experimented since 2016 in the U.S.. Many states in the U.S. are planning to develop inductively charged e-highways. The infrastructure costs involved are huge, but experts counter this contention saying the benefits that accrue include lightweight batteries for EV's at a lesser cost (saving of natural resources in battery manufacture), time saving due to less or no halts or crowding at charging stations, overall reduction in EV costs, reduction of electrical load and spikes on the grid in respective locations during evenings, when most EV's are plugged for recharging and so on.

A Utah State University electric bus outfitted for dynamic wireless charging passes over coils embedded in the pavement at the school's Electric Vehicle and Roadway test track in Logan, Utah, in May 2016. Some states are planning pilot programs that will test wireless electric vehicle charging networks embedded in public roads.

Detroit, the auto capital leads with two downtown roads that would be electrified in the next two years using the inductive charging technology. Florida, Indiana, Pennsylvania and Utah also plan to follow up and test inductive charging on public roads in the next several years.

The link at the base further reveals facts about the dynamic, electromagnetic charging scenario in the U.S. The proponents justify its superiority over the currently mushrooming EV static charging stations with several contentions that may appear premature, but are nevertheless very logical and practical.

“This is a great solution to a problem we have today of how to get to zero emissions,” said Tallis Blalack, managing director of the ASPIRE engineering research center headquartered at Utah State University, which focuses on electric vehicle infrastructure. “If we do this correctly, we can decrease the costs of transportation for everyone.”

Electromagnetic inductive charging is common in everyday life — setting a mobile phone on a wireless charger uses similar technology. On roadways, coils embedded in the pavement transfer magnetic energy to a receiver mounted beneath an electric vehicle to wirelessly charge its battery.

Eventually, wireless road systems could extend electric vehicles’ battery range, reduce the idle time required to recharge batteries and allow freight trucks to transition to electric by making it possible for them to use smaller, less expensive batteries, say proponents of the technology. They envision inductive charging along sections of highway across the country.

Drivers would use a phone app or vehicle control to choose whether to accept a charge from a road’s coils. Users would pay for kilowatts the same way they do at an EV charging station, though the system would be free to drivers during test pilots.

Blalack said the biggest challenge in getting to zero emissions nationally is figuring out how to move the 70% of freight that is now transported by truck.

Without an inductive charging system, it would cost an estimated $150,000 to put EV batteries into each long-haul electric semi, he said. Those batteries would weigh 20,000 pounds, a quarter of a truck’s payload. Charging truck batteries that large would require megawatt chargers to fast charge them, he added.

Inductive charging would eliminate the need for such heavy long-range batteries, Blalack said. Smaller truck batteries would require fewer natural resources to manufacture and would cost only about $15,000.

“We can reduce the cost of transportation for everybody if we have the infrastructure in place,” he said.

Blalack said his center estimates that it would require about $30 billion a year to develop induction road-charging networks in some regions across the country by 2035, primarily on interstate highways.

“It seems like a lot of money, but you’re talking trillions of dollars to buy batteries for long-range vehicles,” he said. “It’s significantly cheaper for us to invest money in infrastructure than build out all these vehicles with long-range batteries.”

“If you can use inductive and static charging, then once you get home, you won’t have those peaks of everyone charging their EVs at once, so you won’t get spikes on the grid,” she said. “This will level off demand throughout the day.”

According to media reports, Sweden will become the world's first country to get a permanently electrified stretch of road, which should allow electric vehicles to recharge their batteries while on the move. The electrified road will be set up by 2025 and once operational would enable EVs to travel greater distances between charging stations.



The highway which is to be electrified will be the E20, connecting Sweden's major cities Stockholm, Gothenburg and Malmo. The E20 highway will be the first of many and is part of the country's plans to have over 3000 km of its roads electrified in the near future. Reports though state that the country is yet to select which type of electric road the highway will feature.

Over the years, Sweden has road tested and trialled three solutions. This includes an overhead electric line for heavy vehicles, charging coils placed beneath the road's asphalt and a charging rail for electric trucks. Of these, induction coils placed under the asphalt seems to be the most popular choice.

Reports state that having electrified roads would not only allow for EVs to travel longer distances, but would also result in more affordable EVs thanks to smaller battery packs.

Amazing... While we continue to fight over ban on decades old diesel vehicles.

This option looks good on paper. It may work in Sweden and other developed countries. However, I don't see it as a viable approach to implement across the globe at least for a decade or two. There are lot of hurdles to this at cost, compatibility and implementation levels. Countries should focus on building more and more fast charging stations. Most of the people who plan to buy an EV at a modest cost wants a good range (500km+) and fast charging capability from the battery point of view. If the car's battery can be charged for a range of 300 km in less than 30 minutes, that is more than enough for now.

While this sounds very futuristic and amazing on paper, wireless charging is extremely inefficient by principle. Even ignoring how it charges slower, wireless chargers need 50% more energy to charge compared to wired chargers. That is 50% of the electricity wasted that could have gone into your battery instead. And this is when said car/mobile whatever is sitting stationary on top of the charging pad with a gap of just a few mm. Not sure how much extra power these are going to waste to charge with a gap of the average car's ground clearance.

It's not that it can't be done, it's just that it's a massive waste of public resources that doesn't make sense unless you are trying to make a tourist attraction (cough cough Dubai)

IIRC ABB was testing earlier via pantograph. So whoever wants to charge it moves into the electrified lane and gets charged within 20 to 30 minutes. Have stopped following the developments on this but I think it will be only for bus and trucks initially.

Looks like the concept of railways with few extra steps to waste resources.
