Virtual Tour of the autartec®-FreiLichtHaus
The autartec® project is making good progress. Since the first public event – the virtual topping-out ceremony in 2015 – the autartec® consortium has continued putting great effort into their research, their developments and planning. The FreiLichtHaus design that had been presented then has now progressed to the planning stage and its realization has been initiated.
The event on April 21, 2016 under the motto »autartec® – from design to realization« held the opportunity for a first virtual tour of the building. The expert audience, who were present in large numbers, was able to gain an impression of the project’s progress.
The event was accompanied by a specialist program including guest lectures on topics such as »Smart Living Technologies« and »architectural design using photovoltaics«, as well as an in-house exhibition presenting the individual autartec®-technologies.
The highlight of the event was a computer-generated, virtually accessible FreiLichtHaus building. The 3D model was embedded into the lakeside surroundings using modern augmented reality technology, underlining the proving the innovative approach to technology pursued in the overall project. The guests’ smartphones and tablet computers served as data goggles, giving a vivid impression of the FreiLichtHaus building.

During the event, a film team from the regional Elsterwelle station shot a feature about floating architecture. In addition to the portraying the existing floating houses on Lake Geierswalde, the feature also referred to plans for autarkic living on the lake as envisioned in the autartec® project.
Fraunhofer IVI Battery Bus Presented at New Mobility 2016
The new mobility congress 2016 with accompanying trade fair was held on April 12 and 13 at the Leipzig exhibition center. Over 60 prominent exhibitors presented their innovative concepts, products and services for the future of mobility in the connected infrastructures of cities and regions. Next to multi-modal transportation concepts and solutions for automated driving, electromobility was a major focus of the trade fair.
In this context, the Fraunhofer IVI had the opportunity to introduce its fast-charging battery bus at the booth of the Leipziger Verkehrsbetriebe (LVB, public transport provider in Leipzig). The electric bus components and the corresponding fast-charging contact system were developed and made series-ready within the collaborative EDDA-Bus project, which was funded by the German Federal Ministry of Education and Research (BMBF). The bus has completed a very successful test run in Dresden's bus network and will start a new test run in Leipzig in the next months.
The battery bus will also be presented at the Ergebniskonferenz des Schaufensters Elektromobilität (conference that introduces the results of the showcase project for electromobility), which will be held immediately following the new mobility congress on April 14 and 15, 2016 at the Leipzig exhibition center.
»Electric Freight Traffic« User’s Day on May 31 in Dresden
In many fields of everyday business life, applications of electromobility have established themselves as viable alternatives. This due partly to an increased public interest in the topic and corresponding funding initiatives, but also partly to economic deliberations of companies and beginning regulatory constraints.
The »Electric Freight Traffic« User’s Day organized by the Fraunhofer IVI will provide logistics service companies and shipping agents with independent and objective information on the opportunities and risks of electric freight traffic. Because these types of companies are faced with stricter emission and immission regulations, the threat of a ban from inner city regions and general economic challenges, they are under especially high pressure to take action.
Plug-In Hybrid City Bus in Dresden
Plug-in hybrid bus at charging station
With the help of federal funding, the Dresdner Verkehrsbetriebe AG (pubic transport provider) and the Fraunhofer IVI are currently testing a plug-in hybrid bus in regular service. The test is part of the Schaufenster Elektromobilität Bayern-Sachsen and has started on March 21st, 2016. The articulated bus provided by Swiss manufacturer Carrosserie Hess AG is equipped with a high-performance battery and power electronics from Vossloh Kiepe GmbH. The recharging process, which takes place at the Gruna bus depot, is carried out using a pantograph system by Schunk.
The installed battery has a nominal energy content of 48 kWh and can be recharged with 330 kW power. With its 38 kWh of usable energy, the bus can be driven fully electrically for a distance of up to 15 km. Due to these characterisitcs, it is especially suited for deployment on bus lines passing through areas that are sensitive in terms of city development.
In addition to the fully electric driving mode and the external recharging process, the test includes an adaptive, self-learning energy and performance management system for hybrid drive buses. The system self-adjusts to the characteristics of each bus line and aims at reducing fuel consumption.
Bus in regular operation
The bus will be tested for a period of several months on the topographically demanding line 61. Due to its varying elevation profile and passenger demand, this line offers ideal conditions for the testing of the energy and performance management system.
Presentation of iTESA Project at CeBIT
iTESA presentation at the BMWi booth held by Mr. E. Pfeiffer (Travelbasys)
Last week, the Fraunhofer IVI presented a first prototype visualization of the iTESA project (intelligent Travellers Early Situation Awareness) at the 2016 CeBIT under the motto »lowering travel risks for safer travel«.The project aims at improving the ability of medium-sized enterprises to comply with the duty of care for their employees. To achieve this aim, the free data streams of the Internet are analyzed in real-time and possible changes of the status quo – due, for example, to natural disasters, political instability or health risks – are forwarded either to the travelers themselves or to other responsible persons.
The consortium, consisting of Software AG, Travelbasys (IT service provider of TUI), Inquence and the Unabhängiges Landeszentrum für Datenschutz in addition to the Fraunhofer IVI, presented their results on the Smart Data booth of the German Federal Ministry of Economic Affairs and Energy (BMWi). In addition, Fraunhofer IVI researcher André Rauschert gave a talk with the title »Digital Empowerment of Medium-Sized Enterprises – the DRP Model«.

IVIon at Energy Storage Europe
Fraunhofer Energy Alliance booth at Energy Storage Europe
»Energy Storage Europe« combines features of a trade show and a conference and was held from March 15 to 17, 2016 in Düsseldorf, Germany. The event offered great opportunities for both researchers and end users to talk about progress made in the field of stationary energy storage systems.
The Fraunhofer IVI presented their battery monitoring system IVIon at the event. The system monitors entire battery modules and stores all information in a data base via radio communication. In addition to the position data, the batteries' temperature and voltage parameters are analyzed and transmitted. On the basis of this measuring data, ageing analyses are executed in real-time, making it possible to control the battery module's performance capacity at any given moment. These features make the approach equally attractive for users and sellers of battery modules.
Fraunhofer IVI to join Shift2Rail
Fraunhofer IVI as part of the consortium Smart DeMain has been nominated by the European Commission as one of nineteen Associated Members to participate in the Shift2Rail programme.
During the period 2016-2023, the consortium – composed of partners Strukton Rail, Acciona, DLR (German Aerospace Center), CEMOSA and Fraunhofer – will contribute to the research programme with solutions for the design and maintenance of infrastructure components and systems in a holistic way.
Electric Fleet Logistics: iHub Project Has Officially Started
March 7, 2016

The consortium partners have been working on their respective tasks since January, and now the project was officially kicked off. At the Berlin office of consortium leader Schenker Deutschland AG, the future of fleet management in general cargo logistics was initiated: FRAMO GmbH, the manufacturer of an electric cargo truck, software company PTV AG and the two research institutes Fraunhofer IVI and Institute of Post-Fossile Logistics PFL have joined forces to develop the IT-based iHub system for the management of mixed diesel-powered and electric truck fleets for a logistics center.
The project is funded by the German Federal Ministry of Economic Affairs and Energy (BMWi) within the scope of the »IKT für Elektromobilität III« program (ICT for Electromobility III), which means that it is a part of the »Digital Agenda 2014-2017« and additionally supports the research goals outlined in the government’s electromobility program.
Electromobility is a particular challenge for general cargo logistics: in this sector, being fast, reliable and on time is especially important. Because of this, logistics service providers need transport vehicles that are always available without any restrictions. Electric vehicles seem at a disadvantage compared to diesel trucks due to their restrictive recharging needs. Therefore, the integration of electric trucks into the vehicle fleets of logistic service providers requires an intelligent management system that is able to compensate for this disadvantage by using dynamic route planning to assign orders to an electric truck only if the truck can execute them with the same level of reliability as would a diesel truck. Applying this kind of control strategy will be the main task of the iHub system currently in development.
In addition to the technological challenges, the system will ensure that the solution developed will be an economically feasible alternative to conventional truck fleets. For an optimization of the entire vehicle fleet’s economic efficiency, parameters such as »State of Use« – a battery’s level of wear and tear – will be utilized to allow a more regular deployment of the electric vehicles.
The systems developed and tested within the project will help to optimally deploy three electric trucks with a maximum total weight of 18 tons each at the Berlin office of Schenker Deutschland AG.
If the partners succeed in providing an IT-based solution that is able to make use of the systemic advantages of electromobility, such as low noise and greenhouse gas emissions, during practical application in a mixed vehicle fleet, an important development step on the way towards post-fossile, emission-free logistics will have been taken.
3rd Dresden Conference »Innovation Electric Bus« – Press Event
Prior to the 3rd Dresden Conference »Innovation Electric Bus«, a press conference was held on December 10, 2015 in the International Congress Center Dresden.
Institute Director Prof. Dr.-Ing. Matthias Klingner talked about the positive experience gained during the implementation of electric buses. »In a collaboration with industry partners, the DockingPrinciple was successfully installed in a fully electric 12-m bus and brought to a pre-series status. The technology’s high quality and reliability was demonstrated during an error-free six-month practical testing period in the regular service of the DVB (Dresden public transport provider). We are very proud that an electric bus – even if it is not a traditional one – is operated again in Dresden after 40 years of absence.«
At the exhibition, visitors can get information on current developments in the field. In addition to its fast charging battery bus, The Fraunhofer IVI will present its battery monitoring system and a tool that is the basis for recommendations regarding the step-wise route implementation of electric buses.
Berlin Conference for IT Users in the Logistics Sector
The Fraunhofer IVI had the opportunity to illustrate their expertise in the fields electric and hybrid commercial vehicles, remote battery diagnosis and optimization of logistics processes at the IT user conference »Telematics, Digital Tachograph, Logistics Software« on November 11 and 12, 2015 in Berlin. A particular highlight for the visitors was the presentation of IVIon, a telemetry platform for the remote diagnosis of traction energy storage units. The use of IVIon enables operators of electric commercial vehicles to compile detailed diagnoses and obtain maintenance advice for their traction batteries.
Through its presence at the conference, the institute was able to point out advantages and pitfalls of the implementation of electric and partially electric commercial vehicles in the logistics sector, and to present itself as a competent advisor in the planning, implementation and operation of these vehicles.
Electric Buses and Micromobility at the »Energy in Future« Conference
The 3rd Dresden Conference »Future in Energy« was held on November 10th and 11th, 2015 at the International Congress Center Dresden. Its aim was to present interesting topics and the newest developments in the fields of electricity generation, energy storage and energy efficiency.
The Fraunhofer IVI headed a conference session entirely dedicated to specific questions relating to the topic »mobility«. In a number of interesting talks, practical examples such as fast-charging electric buses and others were presented. The introduction of a futuristic pedelec as an example of innovative modes of micromobility served as an ideal opportunity to illustrate two core topics of the Fraunhofer IVI research and development portfolio: the importance of new battery systems and their application-oriented characterization.
Today, innovations in the energy sector are more important than ever for the sustainable future of economy and society. The lively exchange between representatives from industry and science and the accompanying exhibition made a valuable contribution to that aim.
Second Review Meeting iCOMPOSE
The second Review Meeting of the ongoing iCOMPOSE project was held on November 3th and 4th, 2015 at the research institution Flanders Make in Lommel (Belgium).
The Fraunhofer IVI presented the results of two years’ successful research and development work to the European Commission and the reviewers. Among others, these results included a model predictive controller for optimal load distribution between batteries and supercaps. As the researchers could prove on the institute’s own test stand, the model predictive controller lowers stress on the battery, saves energy and increases the overall efficiency, which in turn leads to higher ranges for powerful vehicles.
Further research topics of the Fraunhofer IVI within the project are the optimization of public transport vehicles’ indoor air-conditioning and the development of highly dynamic DC/DC converters.
A Temporary Separation
October 16th, 2015
In May 2015, a large European Project that looks at the future of public transport from different relevant angles was revived under the title »European Bus System of the Future 2 – EBSF2«. The Fraunhofer IVI contributes to two larger research topics dealing with city buses. The first of these topics aims at increasing the efficiency of electric buses via an intelligent management system for the auxiliaries, while the second one is concerned with the needs-based adaption of the length of city buses during regular operation. The latter proposes to split an 18 m-long articulated bus so that the 6 m trailer can be detached at the articulation joint and the remaining 12 m segment can be used independently as a fully functional city bus.
This stunning development result is regarded as absolutely new and highly innovative. The concept will be demonstrated with the AutoTram® Extra Grand in the course of 2017. Work on the demonstrator is scheduled to begin within the next month with the division of the vehicle into its three individual segments. Luckily, this separation is only going to be temporary!
A key role within the research project is taken on by Hübner GmbH, the world’s leading manufacturer of joint systems for city buses.

Battery buses will require a detailed evaluation of their possible applications in the long term.
This September, the Fraunhofer IVI successfully completed introduction concepts for the use of battery buses in the route networks of the city of Aachen and the Munich area. In addition to priority lists for the route-by-route introduction of battery buses with fast charging, the locations for the charging stations have been determined and scaled in terms of their charging power.
The analyses have been aligned to the existing operating procedures. Vehicle schedules and graphic schedules were used as a basis, provided that these would not have to be changed with the use of fast charging battery buses.
Further investigations are carried out within the project BEEDeL, focusing on the entire bus network of the Hamburger Hochbahn.

The technology was developed within the scope of the Fraunhofer System Research for Electromobility.
Virtual Topping-out Ceremony »autartec®« - from Idea to Design
On September 16, 2015, a virtual topping-out ceremony was held for the autartec®-FreiLichtHaus on Fraunhofer IVI premises.
The aim of the colloquium, which attracted a large number of professional visitors, was to present the current development state of the autartec® project to the public. The term »virtual« was used in order to clarify that no actual building has been constructed yet, but that the »virtual« planning phase has entered an advanced state manifested by a concrete demonstrator design. This design under the title autartec®-FreiLichtHaus was submitted to the Brandenburg Design Award and nominated after a preliminary screening of the candidates.
The topping-out ceremony was framed by a lecture program consisting of three sessions in correspondence to autartec®’s three sub-projects:
- Design and building materials
- Energy generation and storage
- Controlled consumers and building management system
The traditional topping-out ceremony was the highlight of the event. After the reading of the topping-out address and the hammering of the last nail, a model of the autartec® building in the scale of 1:10 was placed in water, the envisaged surroundings of the future full-size demonstrator.
The guests then had the opportunity to tap into their creativity by folding a paper model of the building from a card kit. Later, they were able to take part in a ride on the AutoTram® ExtraGrand, result of another large-scale project at the Fraunhofer IVI.
Following the lectures, there was an in-house exhibition during which the development states of some of the autartec® technologies were presented and discussed professionally.
autartec® project meeting and strategy workshop
The third autartec® project meeting was held on August 27th, 2015 at the Fraunhofer IVI along with a strategy workshop. During a retrospect of the past year, the first promising research results were presented and the project was positioned within the current research landscape. Both the development of structurally integrated building elements made of fabric-reinforced concrete, which can hold an electric energy storage system designed at the Fraunhofer IVI, and the research on novel utilities systems for autarkic floating buildings are proceeding according to plan.
Now that the building’s overall design and basic technical requirements have been specified, the project partners can begin to design the floating architecture and the technology to be contained in it.
The BMBF-funded Innovativer Wachstumskern autartec® unites 13 industrial enterprises and research institutions from the region South Brandenburg and East Saxony in a joint collaboration.

autartec® FreiLichtHaus submitted for consideration of the Brandenburg Design Prize
June 30th, 2015
Within the BMBF-funded Innovative Regional Growth Core autartec®, a total of 13 industrial enterprises and research institutes from South Brandenburg and East Saxony are currently developing new technologies for autarkic buildings. These technologies and their associated design concepts will then be implemented in the Neue Landschaft Lausitz (New Landscape Lausitz).
A comprehensive design and architecture concept called FreiLichtHaus was developed especially for the project. The autartec® design team, consisting of architect Maren Kupke (AIB GmbH), technical designer Ernst-Eckart Schulze of the Fraunhofer IVI and Thomas Wilde (Wilde Metallbau GmbH), expert in the field of floating houses, have now submitted their concept to the Brandenburg Design Prize.
The autartec® FreiLichtHaus design is characterized by contemporary architecture in symbiosis with structurally integrated, autarkic technologies for the management of water/ wastewater, electric energy and thermal energy. The combination of the components in a floating house is a symbol of a free and independent lifestyle based on modern technology. The building itself consists of three intersecting cubes, each reflecting one of the three autarkic areas. The building’s sculptural design is topologically divided into different surfaces aligned to guarantee an ideal energy output.
The project partners are currently carrying out extensive research on solutions for sustainable building and technologies for autarkic energy supply. The results are to be implemented as central components of the autartec® FreiLichtHaus by the end of the project in 2017.
The research conducted at the Fraunhofer IVI focuses on the development of structurally integrated storage units, for which the institute can draw upon long-standing experience in the field of battery technologies. Additionally, the institute works on solutions for the efficient supply and demand-oriented management of heating and cooling inside the building.
Fraunhofer IVI Partner in Several EU-Funded Projects
The Fraunhofer IVI is involved in numerous new EU-funded projects that have been officially launched in the past weeks. Some of these projects are coordinated by the Fraunhofer IVI, in others the institute participates as partner.
The EU-CIRCLE research project officially launched in June 2015 aims to assess the resilience of interconnected and interdependent critical infrastructures to climate change. The project brings together 20 leading European research/academic institutions, governmental organisations, meteorological services, and industries and SMEs from the climatology and critical infrastructure protection domains in order to derive an innovative framework for supporting the interconnected European Infrastructure’s resilience to climate pressures.
On May 7th, the EU-funded IT2Rail and In2Rail projects will be officially launched in Brussels. They are two of the four flagship projects intended to establish the technical foundations for the Shift2Rail technology initiative of the European rail industry. While IT2Rail focuses on information, ticketing and booking services along transnational travel chains, the main topics of In2Rail are the design, technical construction and maintenance of railway infrastructures. The two projects will unite over 70 partners from industry, railway companies, and research organizations.
The Fraunhofer IVI researchers will contribute their know-how in the fields of information and ticketing services in public transport, infrastructure management and maintenance planning.
Another new European Union research and innovation project launched in May 2015 is TARGET (Training Augmented Reality Generalised Environment Toolkit). The project, bringing together the expertise of 16 organizations, will jointly deliver a pan-European serious gaming platform featuring new tools, techniques, and content for training and assessing skills and competencies of Security Critical Agents (SCAs), including counterterrorism units, border guards and first responders (police, firefighters, ambulance services, civil security agencies, and critical infrastructure operators).
As the second largest technological partner within the project, the Fraunhofer IVI is responsible for major parts of the overall system architecture development. In addition to this conceptual work, the institute will develop the actual core of the training system: the simulator. Moreover, the institute will carry out tasks of integrating components designed jointly by several project partners into the system.
Fraunhofer IVI is the Project Coordinator of INFRALERT (Linear Infrastructure Efficiency Improvement by Automated Learning and Optimised Predictive Maintenance Techniques), a three-year project that has officially started in the beginning of May. The main objective is to develop an expert-based information system to support and automate linear asset infrastructure management for infrastructure such as rail or road networks.
The condition of the land transport infrastructure highly influences the societal and economic competiveness of a region. While the demand for surface transport will significantly increase in the next years, a substantial rise in financial resources for enlarging and maintaining infrastructure networks is not in sight.
In order to still meet the increasing demands, INFRALERT aims at optimizing the performance of existing infrastructure.
The Fraunhofer IVI participates in five more EU projects that will start in the next few weeks.
