Through concrete, ground-breaking changes of the system, and direct recruitment of top female researchers, Chalmers will achieve a significantly more equal gender balance within the faculty over ten years.</b></p>​Like other technical universities, Chalmers has a very low share of women at faculty levels. At Chalmers, the share is currently 22 percent. However, research shows that a more equal gender balance leads to greater scientific success, and also to a better work environment, both for men and women.<br /><br />Therefore, Chalmers is now making a great effort to deal with the skewed gender distribution. The investment is funded by the Chalmers Foundation and has a budget of 300 million SEK over ten years.<br /><img src="/SiteCollectionImages/20180101-20180630/StefanBengtsson_170907_150x200.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px;width:145px;height:193px" /><br />“Different studies clearly show that the academy is not equal today – men and women are judged and treated differently. With this powerful investment, in addition to what we already do, we want to correct the imbalance and in addition become a stronger and more successful university. It's about making better use of the competence of the entire population,&quot; says Stefan Bengtsson, president and CEO of Chalmers.<br /><br />Chalmers has been working on gender equality for a long time. But the new investment, named Genie as an abbreviation of Gender Initiative for Excellence, represents a huge move to speed up the changes.<br /><br />Genie consists mainly of two parts. One is concrete work at each department in order to identify and eliminate structural and cultural barriers that impede women's careers.

Overall, contributions from the government, and the industrial partners CEVT, Scania, Volvo Cars and Volvo Group, enable an investment of 1 billion Swedish krona for the testbed.</b></p>​In 2017, RISE and Chalmers University of Technology were tasked by the Swedish government with creating a testbed for electromobility. It has now been decided that the testbed, called the Swedish Electric Transport Laboratory (SEEL), will be located in the Lindholmen area of Gothenburg, with facilities in the Stockholm region too. RISE and Chalmers will build and own the facility jointly, with industry as the customer base.<br /><br />The aim of SEEL is to strengthen the competitiveness of the Swedish automotive industry, to help Sweden remain at the forefront of innovations in the transport sector, and to accelerate the shift towards a fossil-free Swedish society.<br /><br />SEEL will provide testing for all the different areas of electrified transport. For example, electrified gearboxes and driveshafts for different types of vehicles, drivetrain and component testing for hybrids and electric vehicles, as well as charging and smart power-management. Even the marine and aviation sectors are expected to be able to make use of the testbed.<br /><br /><div>“The automotive industry is extremely important for Sweden, and today we take an important step to secure Swedish automotive jobs in the great transition that is taking place in the transport sector. From fossil to renewable, from petrol and diesel to electricity. Our goal is to make Sweden one of the world's first fossil-free welfare states. And to do that we need to both cut emissions and secure our competitiveness. The Swedish automotive industry will play a key role in this transformation,&quot; says Mikael Damberg, Minister of Enterprise and Innovation.</div> <div><br /></div> <div><img src="/SiteCollectionImages/20180101-20180630/SEEL%20Presskonferens/180629-SEEL-1_750x340px.jpg" alt="" style="margin:5px" /><br /><em>Mikael Damberg, </em><span><em>Minister of Enterprise and Innovation.</em></span><em>, speaking at the launch of SEEL</em><br /><br /></div> Stefan Bengtsson, President and CEO of Chalmers says, &quot;this investment offers great opportunities for education, research and industrial development. The testbed complements the laboratories that Chalmers already has. It is ideal for us to take responsibility as one of the owners, to effectively contribute to rapid knowledge development relating to electric vehicles&quot;.<br /><br />&quot;SEEL is unique in terms of the close collaboration that will take place between industry, institutes and academia. It has all the potential to become a world-leading electromobility testing facility. Together with our testing area for active vehicle safety, AstaZero, and our new test facility for stress-testing automotive electronics and wireless communications, Awitar, SEEL makes RISE well-equipped to be a strong innovation partner for the Swedish automotive industry in the future,&quot; explains RISE CEO Pia Sandvik.<br /><br />&quot;CEVT has a clear mission within the Geely Group to become a world-leading innovation center. Electromobility is an area that allows for new features that will be absolutely essential for our future products to meet tomorrow's requirements for fossil-free vehicles. Development of these features requires deep understanding of components and systems – SEEL will be part of the base we need to continuously develop this knowledge,&quot; says Mats Fägerhag, CEO of CEVT (China Euro Vehicle Technology).<br /><br />&quot;Scania is driving the shift towards a fossil-free transport system. Electrification will be an important part of that journey, and Sweden – with large vehicle makers, green energy and good cooperation between politics, academia and the corporate sector – has unique conditions to take a heavy role in this development globally,&quot; believes Björn Westman, Senior Vice President and head of powertrain development at Scania. &quot;The two electric transport laboratories will be very beneficial for both developing and testing of heavy electric vehicles in Sweden,” he continues.<br /><br />&quot;We in the automotive industry have a major role to play in climate-management, and electrification is an important part of that work,&quot; states Lars Stenqvist, Chief Technology Officer at Volvo Group. “We have started with buses and our first electric trucks, but much more research and development is required. SEEL will help us – and Sweden – to remain a leader in the development of vehicles and systems for climate-neutral transport.&quot;<br /><br />“Volvo Cars’ ambitious electrification strategy means that SEEL will be an important tool when developing and verifying the new technologies we are planning for the coming years,” says Paul Welander, Senior Vice President at Volvo Cars. &quot;During the years 2020-2025, we anticipate a significant shift towards electrified vehicles, so the timing for SEEL is ideal. It is also an investment that will benefit both the industry and society.”<br /><br /><div>The different parts of the test bed will come into use as they become ready, with the lab expected to be fully operational by 2022.</div> <div><br /></div> <div><strong>Text</strong>: Joshua Worth </div> <div><strong>Foto</strong>: Cicci Jonson/RISE <br /></div>Fri, 29 Jun 2018 00:00:00 +0200 Piston Design Lowers Fuel-consumption<p><b>​Volvo’s new Heavy-Duty diesel-engines are more fuel efficient due to a new, smart, wave-shaped, piston design. The new design reduces fuel-consumption by two percent and halves the quantity of particulates. The idea of the piston shape came from Volvo AB. In collaboration with Chalmers, the idea could be refined and realized.</b></p>​Ten years ago, diesel-engineer Jan Eismark was struggling with a problem of reducing emissions from Volvo's engines. The permitted limit values for soot particles and nitrogen oxide emissions were constantly lowered. One big challenge is that the particle and soot emission formation in the combustion chamber is just like a rocking board. The methods limiting soot particles increase nitrogen oxides and the methods that lower nitrogen oxides increase soot particles. The challenge was to lower both. <div><br /></div> <div>Jan Eismark conducted a variety of engine experiments with different pistons and fuel injectors and saw that the soot emissions were very different. The conclusion was that the shape of the combustion chamber, which is completely shaped by the piston top, ought to be very important. </div> <div><br /></div> <div>In the case of a standard piston, the injector is located in the centre of the piston bowl (combustion chamber) and the fuel is sprayed towards the sides of the bowl through a number of orifices in the injector. The combination of heat and pressure causes the fuel to ignite before it reaches the combustion-chamber walls. The flame hits the wall at a speed of up to 50 meters per second, it then spreads along the piston bowl wall at an angle of 180 degrees where-after it collides with the adjacent flames. When the flames collide, they compete for the available oxygen. At the same time, the oxygen in the centre of the combustion chamber is never fully used. </div> <div><br /></div> <div>&quot;We wanted to find a way to lead the flames more inwardly into the combustion chamber to better utilise the available oxygen there&quot;, says Jan Eismark. </div> <div><br /></div> <div>Jan Eismark became an industrial PhD student at Chalmers, to develop the idea together with Chalmers’ researchers through studying fundamental mixing and spray phenomena and combustion mechanisms. </div> <div><br /></div> <div>&quot;The research work in the project has been very extensive and includes, in addition to Volvo's engine experiments, advanced computerised combustion calculation and high-speed recording of the combustion inside the cylinder&quot;, says Ingemar Denbratt, director of the <a href="/en/centres/cerc">Combustion Engine Research Centre</a>, where the research at Chalmers was conducted. </div> <div><br /></div> <div>The research was used to improve the combustion system and resulted in the unique wave design in the piston bowl. The injector position in the centre of the piston bowl has six holes allowing the fuel to be injected in between the waves helping the flames to be directed towards the centre of the piston bowl. The available oxygen could therefore be consumed more efficiently. </div> <div><span style="background-color:initial"><img src="/SiteCollectionImages/Institutioner/M2/Artiklar/lastbilartikel.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px;width:300px;height:200px" /><br /></span><span style="background-color:initial">After that, industrialisation has been taken over by AB Volvo and in 2017 the new piston “arrived” in the first</span><span style="background-color:initial"><br /></span></div> <div>trucks in the United States. Fuel consumption has been reduced by two percent and particulate emissions have been halved. According to AB Volvo, the concept give big fuel savings on Volvo's products and reduction in carbon-dioxide emissions of 5 megaton per year. </div> <div><br /></div> <div><em>(For comparison, a return flight between Sweden and Thailand corresponds to approximately 2.5 tonnes of carbon-dioxide emissions per person, hence 5 megaton of carbon-dioxide emissions corresponds to approximately two million Thailand voyages.)</em></div>Tue, 05 Jun 2018 07:50:00 +0200 power electronics in propulsion research project<p><b>​Energimyndigheten, the Swedish Energy Agency, has granted CEVT and Chalmers with 12 MSEK for a development within propulsion technology.</b></p>​<span style="background-color:initial">The project is called iTEM - integrated Transmission and Electric Machine, and is focused within the field of power electronics. The project will develop a transmission with an integrated e-drive with strongly integrated controls. </span><div><br /><span style="background-color:initial"></span><div>The main goal is to contribute to a better environment globally by developing a hybrid driveline, which makes electric propulsion both affordable and attractive to a wide range of drivers. Furthermore, it is an important goal to increase the innovation capacity in Sweden, for the benefit of the competitiveness of the Swedish automotive industry.</div> <div><br /></div> <div><strong>Cost and efficiency</strong></div> <div>The focus is to solve two of the main issues for powertrain development, namely cost of electrification and efficiency of the complete powertrain. The ambition is to replace fossil fuels as the main energy source for propulsion by developing a device that will give true electric vehicle performance in an affordable PHEV - Plug-in Hybrid Electric Vehicle.</div> <div><br /></div> <div>The iTEM-project will be conducted by CEVT in collaboration with Chalmers. </div> <div><br /></div> <div>Chalmers will develop and evaluate a full-scale inverter based on silicon carbide power transistors. The silicon carbide material has the potential to decrease the heat losses with 50 %, which is a huge benefit both for the cooling system and the electric driving distance.</div> <div><br /></div> <div>CEVT will stand for an innovative gearbox design and integration of gearbox, electric machine, inverter and control system.

With a unique software in their car, the team hopes to wipe the floor with their competitors.</b></p><div>Already available was a whole lab dedicated to the development of self-driving vehicles, a proprietary software platform, and a ready-made electric racing car from last year's Formula Student competition.</div> <div><br />&quot;From there, it was quite a small step, to start a student team to rebuild the car for self-driving and compete in the race class for driverless cars,&quot; says the initiator and supervisor Ola Benderius, assistant professor at the Vehicle Engineering and Autonomous Systems Division.<br /><br /></div> <div>Since last autumn, twelve students from five different master programs have worked to make the car self-driving as part of their master’s thesis.</div> <div><br />&quot;It's extremely fun and educational. It's a brand-new project and we have had a lot of freedom to achieve our goals,&quot; says team manager Emil Rylén, who studies Automotive Engineering.</div> <div> </div> <h3 class="chalmersElement-H3">A dedicated and multifaceted team</h3> <div>The team is divided into three groups, who work with each of the three main elements of self-driving: to perceive and interpret the surroundings, driving planning and control, and mechanical and electronic hardware to execute the control signals. Two of the team members were also in the team that built the car last year.</div> <div><br />&quot;We couldn’t have done it without them. They know and understand how the car works,&quot; says Rylén.</div> <div>He describes the team as a very mixed group, both in terms of nationality, education and skills.</div> <div><br />&quot;Everyone is really dedicated. You definitely do not have to be a racing fan, but rather a technology fan and someone interested in cutting-edge technology.&quot;</div> <div> </div> <h3 class="chalmersElement-H3">Equipment for half a million SEK</h3> <div>To make the car self-driving, they have equipped the car with sensors like GPS, laser radar, dual-lens camera for deep vision, computers, and extra electronics and mechanisms to actuate the brakes, wheel, and accelerator. In total, the equipment cost about half a million SEK, but much of it will be reusable in coming years.</div> <div><br />Financing is already ready for another three years. Interest among the students is very high, as is the industry's interest in recruiting those who participated in the team. Ola Benderius and his two supervisor colleagues – Christian Berger and Björnborg Nguyen – are already gathering next year's team.</div> <div><br />It is also advantageous for the Chalmers lab for self-driving vehicles, <a href="/en/researchinfrastructure/revere/Pages/default.aspx" target="_blank">Revere</a>, to have a team in Formula Student Driverless.</div> <div><br />&quot;We get a chance to showcase Reveres’ abilities and skills, and the team attracts really good students.

The conclusion that choosing one single fuel alternative in the future will probably show itself very difficult and problematic, appeard quite unanimous, and the seminar instead expressed the probable need for two or more different fuel options.<br /></p> <p>  </p> <p><img class="chalmersPosition-FloatLeft" src="/SiteCollectionImages/Areas%20of%20Advance/Energy/lunchseminarier/IMG_0221_Lunchsem-180426_medSamtycke_SOE0001_350x305px.jpg" alt="" style="margin:5px" /></p> <p><em>From left to right: Markus Norström, RISE, Jonas Sjöblom, Maria Grahn och Frances Sprei, Chalmers, Johanna Mossberg och Patrik Klintbom, RISE, Selma Brynolf, Chalmers samt Karin Pettersson, RISE.</em></p> <h6 class="chalmersElement-H6"><em> </em></h6><p><br /></p> <p><br /></p> <p><br /></p> <p><br /></p> <br /><p><br /></p> <p><br /></p> <p><a href="/en/areas-of-advance/energy/events/Pages/Electricity-and-Biofuels_Do-we-need-both.aspx">Agenda »<br /></a></p> <p>Presentation materials:<em><br /></em></p> <p><em>Maria Grahn:</em> <a href="/SiteCollectionDocuments/SO%20Energi/Maria-Grahn_Pres_The-role-of-biofuels-electrofuels-and--180426.pdf">The role of biofuels, electrofuels and electricity in the transformation of the transport sector. »</a></p> <p><em>Patrik Klintbom: </em><a href="/SiteCollectionDocuments/SO%20Energi/Patrik-Klintbom_Pres_Electricity-and-biofuels-synergies-and-competition_180426.pdf">Electricity and biofuels – synergies and competition. »</a></p>Fri, 04 May 2018 14:00:00 +0200 to design for future scenarios<p><b>​Autonomous cars and smart homes will, in the near future, most likely will be a part of our daily lives. But how can we design these systems in a human centred way when they haven’t yet been fully implemented in the society? This was the topic when over 60 practitioners, within the User Experience community GotUX, showed up at the Virtual Development Laboratory at Chalmers.</b></p><div>To have a good understanding of user-centric design in future systems is important for many reasons. One is to avoid technological lock-ins that may not even be desired from a human perspective. These lock-ins can then be very hard to change at a later stage. Feelings of unsafety and mistrust can lead to distress, misuse and avoidance. Including everyday people in the making of big technological systems, influencing our daily lives, can also be argued to be a democratic issue.</div> <div> </div> <h3 class="chalmersElement-H3">Trust in future autonomous vehicles</h3> <div>Imagine yourself sitting in an autonomous car that breaks harshly every time it stops. Even though this doesn’t mean that the car is unsafe the behavior can still make us feel discomfort and mistrust. PhD students, Fredrik Ekman and Mikael Johansson, have done experimental studies about how people perceive different behaviours of autonomous cars, and concluded that defensive and predictable driving felt safer. This knowledge is important because the autonomous cars can then be designed not only to be safe, but also make us feel safe. One could think that as long as a system is safe our feelings of comfort and trust are irrelevant, but if we don’t trust a system we might not use it the way it’s intended, and the risks for accidents or failure increases. Should we distrust the system entirely we would most likely not adopt it at all. </div> <div><div> </div> <h3 class="chalmersElement-H3">Using generative techniques in designing Smart Energy Systems</h3> <div><img class="chalmersPosition-FloatLeft" alt="Bild på Sara Renström" src="/SiteCollectionImages/Institutioner/IMS/Design%20and%20Human%20Factors/Sara%20Renström%20350pxl.jpg" style="height:307px;width:346px;margin:5px 15px" />Surveys and interviews are familiar techniques when trying to understand human thoughts. However the knowledge retrieved is sometimes just too shallow.  Sara Renström, PhD student specialized in user-centred sustainable design, has been using crafting of collages and drawing as a way of reaching more tacit and latent feelings and thoughts. This in the effort of trying to understand what roles people want to play in smart energy systems, and what products, services and systems that could support these roles. Sara explains how she invited residents from the HSB living lab for a workshop including pizza, candy and crafting. <br /><br />Afterwards the collages were presented to the rest of the group members revealing interesting experiences, and was followed by thoughtful discussions, helping contextualizing smart energy technologies in participants’ lives.</div> <div> </div> <div>The discussions on design and user experience continued after the presentations when the host, Graduate school Human Technology and Design, offered everyone snacks, drinks and mingle.</div> <div> </div></div> <h4 class="chalmersElement-H4">Facts</h4> <div>GOTUX is local chapter of the Interaction Design Association, IXDA, a member-supported organization dedicated to the discipline of interaction design. <a href=""></a></div> <div><br /><a href="">The graduate school Human Technology and Design</a> is common in the two departments Industrial and Materials Science and Computer Science and Engineering.

The interest in cooperation within the field has increased, both in the automotive industry and from other universities, in the Gothenburg region as well as internationally.<br /><br />&quot;It is great that our research is gaining recognition,&quot; says Jonas Sjöberg. “I have been able to form a research group with young researchers, who have taken on new research challenges in a new and growing field.”<br /><br /><img src="/SiteCollectionImages/Institutioner/E2/Nyheter/Aktiv%20trafiksäkerhet%20gav%20Volvostipendium/Jonas_Sjöberg_300px.jpg" alt="Jonas Sjöberg" class="chalmersPosition-FloatRight" style="margin:5px;width:230px;height:300px" />In the justification for the scholarship, it is emphasized that Jonas Sjöberg successfully has developed the field of electromobility and autonomous driving. Together with his research group, and often in cooperation with other researchers at the Department of Electrical Engineering, he has worked with system aspects, dimensioning, modeling and control of hybrid drive lines. The results have enabled more exact calculations of the &quot;best&quot; design for challenges in electromobility and how to control the energy management in the vehicle, which previously relied on rough estimates.<br /><br />One of the industrial PhD student projects that Jonas has been engaged in, within the Intelligent Vehicle Safety System Program, has resulted in a patent, which subsequently has been applied in newer Volvo cars where a system of emergency braking helps avoiding accidents in left-hand turns. <br /><br />His research in recent years has been focused on issues concerning autonomous driving.<br /><br />&quot;What appeals the most to me within this research area is that we constantly are faced with so multifaceted and complex problems, that for every new progress there is always more to understand,&quot; says Jonas Sjöberg. “It is also important to constantly have the interaction between human beings and technology in focus.”<br /><br /><strong>Prize ceremony and seminar</strong><br />On 29 May, the prize ceremony will be held where Jonas Sjöberg is awarded the 2017 Håkan Frisinger scholarship. In connection with this, he will give a lecture in Swedish entitled ”Historien bakom avancerad forskning: från neuronnät till självkörande bilar”.<br /><br />&quot;I´m honored to receive the scholarship,&quot; he says. “During the lecture I intend to talk about how my research has evolved up to today and how coincidences sometimes can play a role.”<br /><br />Besides Jonas Sjöberg, you also have the opportunity to listen to Bo Wahlberg, Professor in automatic control at KTH, Nikolce Murgovski, Assistant Professor in mechatronics at Chalmers, and Erik Coelingh, technology advisor at Zenuity AB and Adjunct Professor at Chalmers.

A common cause is when the vehicle has been hit in the rear. Many of these accidents could be avoided by driving an electric car. How this could be done is shown in Adithya Arikere’s PhD thesis.</b></p><div><span style="background-color:initial">“In my project, we tried to find novel active safety applications for electrified drivetrains that cannot be achieved or at least performed as well with traditional internal combustion engines” says Adithya Arikere.</span><br /></div> <div><br /></div> <div>Electric drives have a lot of advantages over internal combustion engines. They have fast and reliable response, precise and accurate control, max torque from standstill and more. Some of these can be exploited to achieve novel or improved active safety functionality. </div> <div><br /></div> <div>&quot;A simple example is if you can detect that you are about to be hit from behind and you have the free space in front to accelerate and get out the way, you can do so with an electrified drivetrain&quot; says Adithya Arikere. </div> <div><br /></div> <div>This cannot be done reliably with an internal combustion engine since they have poor low-end torque, large response times and the transmission can be in the wrong gear. But with electric drives which deliver their peak torque at low speeds, have short response times and typically don’t need a transmission, this can be easily and reliably achieved. Adithya Arikere has investigated three scenarios in detail: the rear-end collision, obstacle avoidance with oncoming traffic and intersection accidents. </div> <div><br /></div> <div>&quot;We have found that in each case, the quick and reliable response of electric drives can be used to perform interventions that can avoid or mitigate accidents and yield a significant safety benefit&quot; says Adithya Arikere</div> <div><br /></div> <div>Since his project deals with finding novel active safety applications for electrified drivetrains he believes it can make electrified vehicles of the future safer and consequently, also make them more attractive to consumers since these safety functions cannot be achieved with traditional internal combustion engine based vehicles.

All with a focus on components and systems studies for electromobility.  Jonas Fredriksson, Professor in electrical engineering, explains.</b></p><strong>​Who is the summer school intended for?</strong><br />It is intended primarily for PhD students with interest and research profile in electromobility, at all Swedish universities. However, researchers from the Centre’s industrial partners are also welcome.<br /><br /><strong>Why do you arrange a summer school?</strong><br />Swedish Electromobility Centre is a national centre of excellence with doctoral students and researchers at several Swedish universities. This means that common activities lead to a lot of traveling for some members. In the summer school we gather in one place for a week and study and discuss electromobility focused together. In addition, participants get the opportunity to get to know each other and create contacts with other researchers and research students who deal with different aspects of electric mobility.<br /><br /><strong>What will I learn during the week?</strong><br />The course gives both overview and in-depth knowledge of key components such as batteries, fuel cells and electrical machines as well as tools for systems studies that will be used for evaluation, design and construction of vehicle drive systems.<br /> <br /><strong>Why should I attend – aren’t the courses I take at my university enough?</strong><br />Courses taken within your own research school are usually in-depth courses within your research area. Because electromobility is an interdisciplinary research field, finding courses that provide a comprehensive picture can be difficult. The summer school provides both a broader understanding of the electromobility area and of where the research challenges lie within the different parts of the area.<br /><br /><strong>I want to participate. How do I proceed?</strong><br />You register for the course at Swedish Electromobility Centre’s website. The course itself and course material are free, but you pay for travel, accommodation and living. During an intensive week, lectures and practical exercises are mixed with social activities. The examination consists of active participation during the week as well as the solution of a project assignment that will be reported on a separate occasion.<br /><br /><strong>Swedish Electromobility Center summer school: Components and systems for electromobility</strong><br /><strong>When</strong>: 21-25 May 2018<br /><strong>Where</strong>: <a href="">Toftaholm</a>, outside Värnamo.<br /><strong>Registration</strong>: By April 12th<br /><a href="">Read more about the summer school and register &gt;&gt;</a><br />Thu, 29 Mar 2018 00:00:00 +0200 lunch seminar on FFI-projects<p><b>​When Areas of Advance Transport and Energy invited to a lunch seminar on successful, industry relevant research projects, focus on FFI, it became apparent that the subject is interesting - even when the amount of available seats was doubled the seminar was fully booked within short.</b></p>Areas of Advance Transport and Energy last week welcomed Peter Kasche, from the Swedish Energy Agency, and Lars Davidson, from the department of Mechanic and Maritime sciences, to a lunch seminar on the subject successful, industry relevant research projects, focus on FFI.
