Tesla Launch Pricing Experiment in Norway Electric car maker Tesla are to trial a new charging pricing structure in Norway and Sweden. Drivers can take advantage of cheaper charging on selected days. Although electric car sales are picking up across the globe, Norway remains a world-leader and a very important market for manufacturers. Last year, sales of electric cars in Norway outstripped those powered by other means, for the first time anywhere in the world. Now with Norway's winter holidays looming, Tesla are reducing the price of their supercharging stations by 50% on certain days. The aim is to encourage owners to travel on quieter days.
