Sharing electric cars is a convenient option in the city: Giving up your own car and sharing one with other people instead – car sharing is the hot trend of the moment.
But if it’s going to succeed with electric vehicles, charging times need to be shorter and booking processes simpler. That means a straightforward process for finding the electric car that best suits your needs as well as a wide-ranging charging infrastructure. At the eCarTec trade fair in Munich on October 22, six Fraunhofer Institutes will be demonstrating the technology that will make e car sharing a viable concept.
Every day, private motor transportation causes traffic jams, pollution and a shortage of parking spaces. The number one mode of transportation – the automobile – is one of the biggest burdens on urban spaces and their inhabitants. But does it have to be this way?
Other options have emerged that offer reliable, low-emission mobility in cities and the surrounding areas: not just electromobility, but digital networking and car sharing, too. In a project entitled “Shared use of e-mobility: vehicles, data and infrastructure” (GeMo for short), six Fraunhofer Institutes are combining these trends, which so far have been worked on virtually in isolation, and making them accessible.
The result: a comprehensive package of eight technological innovations that are making shared e-vehicles the true superheroes of the city. To better demonstrate these advances, the institutes have bundled them in a concept car. With access to a pioneering infrastructure featuring inductive charging stations and cloud-based charging management, charging the e-car becomes fast and straightforward.
What’s more, if it’s a car sharing vehicle, drivers can easily find it in the city and book it using a convenient app. An on-board unit enables the car to communicate with various cloud services, other e vehicles and the charging infrastructure. As a result, the car can provide data on its position, or how much charge its battery has remaining.
“To make shared mobility a reality, we have to link vehicles, data and infrastructure. That was the core of our project,” says Florian Rothfuss, the person in charge of the GeMo project at consortium leader Fraunhofer IAO. “What we need are applicable information and communication solutions that are both very reliable and easy to use. However, everything depends on having a convenient charging infrastructure integrated within the city.”
The six Fraunhofer Institutes will reveal their solutions on October 22 at eCarTec in Munich (Booth 418). Naturally, visitors will have the chance to take a close look at the concept car and get information about the new technologies straight from the developers. Experts from automotive manufacturing as well as urban and project development will also be on hand to discuss the future of mobility.
Working on the GeMo project are researchers from the Fraunhofer Institutes for Embedded Systems and Communication Technologies ESK in Munich, for Open Communication Systems FOKUS in Berlin, for Industrial Engineering IAO in Stuttgart, for Integrated Circuits IIS in Erlangen, for Solar Energy Systems ISE in Freiburg as well as for Transportation and Infrastructure Systems IVI in Dresden.
The latest innovations in detail:
• An inductive, bidirectional charging system with 22 kilowatts of power and up to 95 percent efficiency from grid to battery ensures rapid charging.
• Using a laser scanner, the driver can position the car precisely over the inductive charging station.
• The latter has all of the charging components integrated in an underground shaft, keeping it concealed from view.
• Cloud-based charging management optimizes the charging processes for multiple shared e-cars.
• An on-board unit ensures seamless communication between vehicles in the car sharing fleet.
• Cloud-based mobility services make it possible for users to register, personalize their profiles, book a car or charging station and receive invoices for usage – all with a convenient app.
• A cloud collects mobility-relevant data over an internet connection, provides that data to other services and consequently links the various subsystems.
• Cars are localized seamlessly, even in parking garages and underground parking lots, thanks to a combination of a Wi-Fi positioning system, GPS, inertial sensors and movement models (awiloc®). This means users can easily locate available vehicles.

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.
Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....
The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
