Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.
Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year. This will require new technical solutions for charging infrastructure: charging should take place as quickly as possible and, as far as possible, without the driver’s involvement.

Researchers at TU Graz’s Institute of Automotive Engineering have now developed an automated, conductive – in other words, cable-based – robotic system that for the first time allows for charging of different vehicles entering the charging space one after the other.
The comfort charging system is designed for use with standard charging plugs (CCS), meaning that no specific vehicle adaptations are necessary. The project partners were BMW AG, headquartered in Munich; MAGNA Steyr Engineering Graz; Linz-based automation specialists KEBA and the Austrian Society of Automotive Engineers (ÖVK) in Vienna.
Bernhard Walzel, who oversees this research focus at TU Graz as part of his dissertation, explains the revolutionary methodology: “For the first time we have found a way to automatically recharge several vehicles, one after another, using a robotic charging station, without the need to adapt the vehicles. The robot recognises the charging socket by means of sophisticated camera technology and can charge several e-cars in sequence after they drive into the charging station. Problems associated with the vehicle’s parking positioning on the station were solved, so the system still works even when a vehicle is not parked in an exact position.”
As Walzel points out, another unique feature is that the robot can operate in various light conditions indoors as well as outdoors.
Automated conductive charging of e-vehicles
A major challenge facing the researchers was programming and integrating sensor technology to identify the exact position and type of vehicle and charging socket. Working in close collaboration with the Institute of Computer Graphics and Vision at TU Graz, the robotic charging system was fitted with several cameras. These recognise the position and type of the charging socket and inform the robot where to plug in the charging cable.
The aim was to design the sensors and charging robot in such a way that it was suited to use with various vehicle types and parking positions, without the need for any changes to the vehicle itself. This means the system can operate with all standard charging plugs. In order to solve the problem, the researchers devised a complex mechatronic system consisting of sensors, robot kinematics and robot control elements.
The technology developed in Graz is designed for automated high-capacity charging of e-vehicles, supplying them with sufficient power to cover long distances; charging lasts only a few minutes. Such high-capacity charging requires innovative liquid-cooled plugs and cables, which can be easily connected to the vehicle using the robot-controlled rapid charging system. The technology also provides a solution that could be implemented for fully automated parking and charging of e-vehicles in future.
The charging system design and experiments on sensor technologies were carried out as part of contract research commissioned by the Austrian Society of Automotive Engineers (ÖVK). The prototyping and testing of the charging system formed part of a project entitled “KoMoT – Komfortable Mobilität mittels Technologieintegration” (“convenient mobility by means of technology integration”). Funding was provided by the Austrian Research Promotion Agency (FFG) and the Austrian Federal Ministry of Transport, Innovation and Technology (bmvit).
This research area is anchored in the Field of Expertise "Mobility & Production", one of five strategic research FoE of TU Graz.

Thin-film solar cells made of crystalline silicon are inexpensive and achieve efficiencies of a good 14 percent. However, they could do even better if their shiny surfaces reflected less light. A team led by Prof. Christiane Becker from the Helmholtz-Zentrum Berlin (HZB) has now patented a sophisticated new solution to this problem.
"It is not enough simply to bring more light into the cell," says Christiane Becker. Such surface structures can even ultimately reduce the efficiency by...
A study in the journal Bulletin of Marine Science describes a new, blood-red species of octocoral found in Panama. The species in the genus Thesea was discovered in the threatened low-light reef environment on Hannibal Bank, 60 kilometers off mainland Pacific Panama, by researchers at the Smithsonian Tropical Research Institute in Panama (STRI) and the Centro de Investigación en Ciencias del Mar y Limnología (CIMAR) at the University of Costa Rica.
Scientists established the new species, Thesea dalioi, by comparing its physical traits, such as branch thickness and the bright red colony color, with the...

Graphene is considered a promising candidate for the nanoelectronics of the future. In theory, it should allow clock rates up to a thousand times faster than today’s silicon-based electronics. Scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) and the University of Duisburg-Essen (UDE), in cooperation with the Max Planck Institute for Polymer Research (MPI-P), have now shown for the first time that graphene can actually convert electronic signals with frequencies in the gigahertz range – which correspond to today’s clock rates – extremely efficiently into signals with several times higher frequency. The researchers present their results in the scientific journal “Nature”.
Graphene – an ultrathin material consisting of a single layer of interlinked carbon atoms – is considered a promising candidate for the nanoelectronics of the...
