Sweden announces about first vehicle-charging electrified road. Owing to the technology that is called the conductive charging it works by recharging the electrical batteries of vehicles as they drive along the road. The 1.2-mile-long stretch of electrified road was developed by eRoadArlanda – a consortium including vehicle manufacturer DAF, property developers, technology companies and academic institutions. “The vehicle is connected to an electrified road and, as long as the vehicle is above the rail, a movable arm transfers power from the rail to the vehicle’s battery. The current disconnects when the vehicle stops, allowing the system to calculate how much energy a vehicle is using and then debiting the costs per vehicle and user. It eliminates the need for roadside charging posts and means batteries can be smaller and manufacturing costs lower” mentioned IFLSCIANCE. Not only do the rails supposedly reduce carbon emissions by 90 percent, the company says it is 75 percent cheaper than the cost of fuel.
“Electrified roads in Sweden with conductive feeds is expected to cost about SEK 80 billion [$9.5 billion],” said the company. “If we assume that electric cars with small batteries cost the same as internal-combustion cars, it would take less than three years to pay for the electrification of the roads.”
While other nations are developing similar systems and technologies, Sweden’s announcement is the “first of its kind” to allow both commercial and passenger vehicles the opportunity to recharge while driving.
“As far as we know, it’s the most cost-efficient electric road technology so far,” Hans Säll chairman of the eRoadArlanda told Dezeen. “It will make it possible to have smaller instead of bigger batteries, which will lower battery cost and their negative impact from a sustainability point of view,” said Säll. “It will also decrease the cost and space needed for stationary charging stations along our highways.”
