The German government opened its first electric highway on a six-mile stretch between Frankfurt and Darmstadt. The first ehighway was launched by Sweden in 2016, the technology used in Germany is more or less the same – It uses 670-volt direct-current overhead cables from which the trucks draw electricity and recharge their batteries on the go. The trucks can draw power even when they brake, making this technology equally valuable in case of a traffic jam.
“Electrified overhead line trucks are a particularly efficient solution on the way to climate-neutral freight transport. We’ve tested the system for many years on private test routes. We’re now inaugurating practical tests on the A5 autobahn between Frankfurt and Darmstadt, and two further test stretches will follow in the states of Schleswig-Holstein and Baden-Wurttemberg,” said Rita Schwarzeluhr-Sutter, Parliamentary State Secretary at the Federal Ministry for the Environment, Nature Conservation and Nuclear Safety (BMU)
This electric highway is made using Siemens ehighway technology which is designed for special kind of trucks which have power-drawing equipment mounted on their roof. These hybrid trucks when connected with power cables of this electric highway, can run with a speed of 90 kmph. The trucks simultaneously charge their batteries so when they merge with city roads, they can keep running from the stored power. Siemens says that the eHighway system is twice as efficient as conventional internal combustion engines and helps reduces local air pollution and contributes significantly. According to Siemens’ website, electrifying truck transportation could also save a ton of fuel: 20,000 euros worth for every truck traveling 62,000 miles (100,000 km).
Meanwhile, Sweden is building a road that can charge both buses and cars on the go. The Swedish city of Lund will be the first in the world to open up a prototype of an electric road. The one-kilometer long stretch will be built by Elonroad which says that electronic road technology will make it possible for batteries to be 80% smaller. Smaller batteries will mean cheaper electric vehicles, faster charging and ultimately fewer costs. Lund’s electric road will also be the first electric road with ground level power system. Sweden will start building the first phase in 2020.
