[Headlines] (HL-과학/기술/교육) Electrified Road Can Charge Moving Vehicles

Major world automakers have already invested heavily in electric vehicles and related technology – and they are committed to keep doing so. Some have even promised to stop producing vehicles that run only on gas or diesel fuel in the future. The changes to the auto industry demonstrate the growing number of buyers willing to spend more money on environmentally friendly cars. But one of the main issues with the technology is that drivers need to charge the batteries often to be able to travel longer distances. The batteries themselves can also greatly increase the price of the vehicles. They can also be very costly to replace. Now, a new technology is being developed and tested in Sweden to help resolve these issues. Engineers there have created what is thought to be the world’s first operating electrified road. A Swedish company, Elways, invented the technology. The project, involving several companies, is called eRoadArlanda. A large, specially built electric truck transports goods along a two-kilometer-long stretch of road from Stockholm’s Arlanda airport. The truck’s battery is charged from the electrified road as it travels.

CEO Hans Saell has led the project since 2013. He explains that the technology works in a simple way. A 15-centimeter-wide electrical rail is built into the road. The vehicle contains equipment that automatically senses the electrified road. An arm then lowers from the vehicle to make contact with the rail. Saell says the system is designed to make continuous charging on the road effortless for the driver. “If you pass another vehicle, or if you leave the electric road, or if you come to a roundabout where we have no rails, it goes up automatically. So once again, you don’t have to think about it at all as a driver.” He says that currently, the battery makes up about half the total cost of a 100-percent electric passenger vehicle. “And if you can have electric roads, you need maybe half the size of the battery, or even smaller. So that reduces, of course, the cost of the car.”
