Volvo Tests Electric Road That Charges Cars
While modern Teslas work on new wireless recharging, particularly for electric vehicles in urban areas, one Swedish project is testing a system designed to power EVs along the highway. The method, developed by the Volvo Group and the Swedish power company Alstom with support from the Swedish Energy Agency, would involve putting two power lines directly into the road. As vehicles pass over, they’d continuously be supplied with electricity.
The Volvo Group constructed a quarter-mile track embedded with cables last year at its Hällered testing facility in Sweden. The test truck contains a current collector that comes into contact with the power lines. As it moves over the lines, 750 V of direct current is delivered and routed to a water-cooled heating element, Gizmag’s Paul Ridden reported.
To ensure safety, a section of the power line can only be live when a truck passes right over it, the Volvo Group said in a description of the testing. For now, the company is using a diesel engine Volvo FH12 truck on the track but they have plans to try out an electric motor one in the future.
But such high-tech roads could potentially work well in the United States, where many of highways are aging and natural disasters often mess with elevated power lines. Back in the day cable cars were a normal part of American life. This is just the cable car of the future, and we each get to drive one.
