Electromobility: Researchers are developing new technology for charging e-cars while driving | message
Charge e-cars while driving
According to media reports, the team is working on a project called “eCharge”. This is supposed to be a technology that enables contactless charging with the help of induction modules in the road surface. “When a new road is built or renewed, the coils are installed at a depth of about ten centimeters and covered with an asphalt layer so that they cannot be seen from the outside,” explained Professor Michael Wistuba from the Institute for Roads at the TU Braunschweig in a press release .
According to the researchers, this technology can both reduce battery costs and improve the charging infrastructure for electric vehicles. According to Professor Wistuba, a range extension of up to 20 percent could be achieved with the technology of contactless charging. For this purpose, so-called E-corridors with a length of 25 kilometers could be built on motorways.
Gained initial experience with inductive charging
According to information from Braunschweiger Verkehrs-GmbH, a total of four e-articulated buses have been running in the Braunschweig inner city ring since 2015 using inductive charging technology.
According to Wistuba, the new concept provides that a cable is led out of the street at a distance of 1.65 meters and then bundled and ends up in a management unit at intervals of around 90 meters. Research into suitable building materials for the road surface is also the focus of the current project.
Other research teams are also working on this technology
Researchers at Stanford University in America have long been working on a technology for contactless charging. As a communication shows, this system already achieves a transmission efficiency of around 92 percent. “In order to actually charge a car while driving, we still have to significantly increase the performance of the energy transfer, but I don’t see any major obstacles on the way,” says Shanhui Fan, Professor of Electrical Engineering at Stanford University, according to the press release. .
Meanwhile, inductive charging technology can bring great progress not only in the area of passenger transportation. Contactless charging can also lead to increased efficiency and cost savings in industry. A conceivable scenario would be, for example, to charge robots in warehouses while they are working without contact, thereby ensuring 24/7 operation.
