In the process of popularization of electric vehicles, there are many resistance factors. Among them, the most important thing for car owners is battery life and charging convenience.

Sweden completes its first experimental project: wireless charging of trucks on the road

However, if the road charging technology is mature and the electric vehicle can charge while driving, the electric vehicle will be favored by more consumers. At present, many technical teams at home and abroad are conducting such tests.

According to foreign media reports, a company called electreon wireless has completed its first experimental project in Sweden, charging a 40 ton experimental truck wirelessly while driving.

Its wireless charging technology scheme is to lay copper coils along the road forward direction 8 cm below the asphalt pavement of the public road. The coil transmits the electric energy to the energy receiver under the vehicle chassis in the way of wireless transmission to provide the power for charging the vehicle.

According to Noam Ilan, vice president of business development of electrion wireless, the cost of this kind of intelligent road is also relatively high, but their team can ensure that the construction cost of this kind of intelligent road is controlled below 1 million US dollars (about 6.9 million yuan) / km.

Moreover, the construction efficiency is also very high, and the construction time per kilometer is only 1-2 nights. Although the initial investment is large, but thanks to the wireless charging Road, it can save a lot of power and time costs for electric vehicles. Therefore, after the completion of the intelligent road system, the later stage also has a higher income.

In addition, the company plans to use solar power to generate electricity and then provide energy for road charging systems. In this way, when they build roads, they can save a lot of construction costs.

Finally, Noam Ilan, vice president, said the company’s first smart road deployment in Sweden was progressing well.

They will be deployed in February 2020, will be completed within the year, and will continue to test the truck and a bus. By the end of 2020, the company will complete a 1.6km test in Sweden.
