Fraunhofer Institute for Transportation and Infrastructure Systems IVI

The annual congress of the Federal Association of the German Energy and Water Industries (BDEW) is one of the most important networking events of the sector. This year’s event was held on June 13 and 14 in Berlin and attracted over 1600 participants from politics, industry and science. The program featured lectures by high-profile politicians and executives, panel discussions on six different key topics, and a large exhibition that allowed enterprises and institutions to present their work in the fields of energy and water.

Next to digitalization, energy policy and problems of grid stability and flexibility, electromobility was one of the congress’s key topics. In this context, Sven Klausner presented an innovative underfloor charging system for electric vehicles, which was developed at the Fraunhofer IVI and displayed at the joint booth of the Fraunhofer ICT Group. The great advantage of this system is that it does not rely on charging cables and plugs, which allows the fast charging of vehicles in public spaces, for instance, at charging stations. The same vehicle interface is used for slow recharging in private spaces, such as garages. In addition, it is possible to automate the entire recharging process. With these characteristics, the underfloor charging system is especially well-suited to promote the spread of electromobility.

Cooperative Intelligent Transport Systems improve transport safety. They help use the available transport infrastructure more effectively and reduce traffic-related emissions. Technologies for vehicle-to-infrastructure communication (V2X) thereby play an important role. The introduction of these new systems is challenging for cities and municipalities when modernizing their transport infrastructure.

Commissioned by the city of Berlin and in cooperation with the Fraunhofer FOKUS and IVM – Institut für vernetzte Mobilität, the Fraunhofer IVI has produced a study that shows options and strategies of cities/municipalities for exploiting the potentials of V2X. Based on a technology assessment, V2X introduction strategies are derived, the costs of the overall system and the use case Berlin are analyzed and operator models are discussed. The main result of the study is an approach for cities /municipalities to determine suitable strategies and measures for the exploitation of V2X potentials.

On May 22 and 23, the second General Assembly within the AEROFLEX „Aerodynamic and Flexible Trucks for Next Generation of Long Distance Road Transport“ research project was held in Berlin.

The project’s aim is the development and implementation of novel technologies and concepts that take the entire vehicle into account and that increase its safety, comfort, as well as energy and cost efficiency. At the same time, the different requirements of users and providers in various fields of intermodal freight transport are to be fulfilled through the application of flexibly adaptable solutions.

The key development areas are:

• An Advanced Energy Management Powertrain (AEMPT) architecture and control for distributed electric hybrid powertrains, including a smart steerable dolly,
• A wide range of Aerodynamic Features and devices for the Complete Vehicle, a selection will be made from: Active / passive geometry and Active / passive flow control,
• Smart Loading Units for overall efficiency gains for volume and weight freight,
• A study on Innovative Front End Design to ensure survivability of vulnerable road users in crashes up to 50 km/h.

The consortium consisting of 23 renowned partners from industry, component suppliers and research institutions met at the German Aerospace Center (DLR) in Berlin in order to discuss the current development status, as well as the state of implementation of the innovations planned within the project. The consortium receives support in these matters from a sounding board consisting of representatives of (European) politics, vehicle industry and the logistics sector.

The Fraunhofer IVI contributed their expertise in the field of hybrid propulsion systems and was responsible for the development of an electric dolly. This dolly helps to reduce CO₂ emissions through electric drive support and the recovery of braking energy, as well as to implement autonomous, locally emission-free maneuvering without a conventional tractor unit.

The International Transport Forum Summit was held from May 23 to 25 in Leipzig this year. Under the topic of »Transport Safety and Security«, more than 1400 transport and logistics experts, researchers and politicians participated in the summit to exchange ideas and opinions regarding the increasingly complex challenges in transport.

The Fraunhofer Institute for Transportation and Infrastructure Systems IVI gave a poster presentation at the joint booth of the Saxon Energy Agency SAENA. Institute representatives were available for discussions about various topics such as the digital test field Dresden and real traffic conditions for automated and connected driving functions. Fraunhofer IVI researcher Rico Auerswald held a presentation at the Open Sage Café on May 24, providing insights into the scientific work of the institute in the fields of autonomous driving and Intelligent Transport Systems.

One of the most important aspects of development towards self-driving systems is the connectedness of different actors, such as traffic lights and vehicles. »Bevor a traffic light turns red or green, it can broadcast this information to traffic participants. Drivers can prepare for this situation and adapt their speed,« said Richard Fritzsche of the Fraunhofer IVI in an interview with the Leipzig-based newspaper LVZ. The advantages are not only visible in the increased security for other traffic participants, but also in traffic flow and reduced emissions.

The battery life of electric vehicles still presents a financial challenge for the electrification of the transport sector. That is why the Fraunhofer institute for Transportation and Infrastructure IVI, expert in the field of Lithium-Ion batteries, and real-time electric vehicle data specialist ViriCiti, have started a unique collaboration. This collaboration aims to prolong battery life and lower total cost of ownership of electric buses and trucks. Over the past months, they researched how battery life can be extended by altering specific aspects of operations. The outcome is a battery stress report that gives operation-specific advice on how to prolong the battery life.
