Swedish Electromobility Centre (formerly Swedish Electric and Hybrid Vehicle Centre, SHC) is a national centre of excellence for hybrid and electric vehicle technology. It was established in 2007 by the Swedish Energy Agency in partnership with the Swedish automotive industry and academia to promote collaboration and maintain Sweden’s position among leading nations in automotive research and development. We provide strategic knowledge and competence related to electric and hybrid vehicles through education, research and development, and facilitate cooperation between industry and academia.
Swedish Electromobility Centre includes four industrial partners – AB Volvo, Volvo Car Corporation, Scania CV AB and Autoliv – and five technical universities – Chalmers University of Technology, Lund University, KTH Royal Institute of Technology, Linköping University and Uppsala University.
Swedish Electromobility Centre builds competence in the electric and hybrid vehicle area by financing research projects carried out within the centre and by managing knowledge transfer between and within academy, industry and society. Furthermore, we synchronise Swedish research and initiate smaller studies within the fuel cell area through the project Technology watch of fuel cells. We also host research activities such as a daily analysis of energy efficient vehicles and are project leaders and responsible for the steering council in FFI Electromobility . Through our activities we are one of the stakeholders in national and international discussions within the electric and hybrid vehicle area.
Our research focuses on five thematic areas; System studies and methodologies, Electrical machines and drives, Energy storage, Vehicle analysis and Fuel cells:
System studies and methodologies
Within the area System studies and methodologies we develop methods and algorithms, necessary for providing electric and hybrid vehicles with the best properties possible. A central part of our research exploits dynamic models, computational methods and simulation techniques to study system solutions.
The techniques that we develop aim at improving vehicle properties such as energy efficiency, reliability or safety. A common theme is the increased use of information, obtained from various sensors, both from the vehicle itself and the surrounding traffic environment.
Electrical machines and drives
The research within the area Electrical machines and drives has a focus on developing and collecting knowledge about energy transformation techniques for propulsion of completely or partly electrically propelled vehicles, and on construction and manufacture of such techniques.
One of our fields of interest is how the electrical machine can relieve the pressure on the combustion engine, considering different hybrid vehicle types and machine types. We also study alternative materials and manufacturing techniques which can make electrical machines in hybrid vehicles cheaper and more efficient.
Within the power electronics area we evaluate the potential of semiconductor components in vehicle applications. We concentrate mainly on cooling of power electronics and electrical machines, but also include charging systems for traction batteries and support systems such as electrically driven air compressors and direct/indirect power steering.
Finally, we aim to maintain statutory safety and EMC by increasing the knowledge, and to study work methods and equipment in order to maximize safety for workshop staff, rescue personnel and vehicle users.
Within the area Energy storage we build knowledge for maximum exploitation of energy storage systems, without renouncing the demands on lifetime. Our research supports the companies working with development and application of battery and supercondensator systems for hybrid vehicles.
One focus is on evaluation of battery management systems for hybrid vehicles. This research is performed in close collaboration with the vehicle industry. Another important direction is a more profound characterization of battery cells and components, in order to gather knowledge about the physical mechanisms behind aging.
In addition, we do research on innovative components and cells which can support a future Swedish production of high-performance, low-cost batteries. The knowledge base that we are building is crucial for the technology of the coming battery generations.
Vehicle analysis explores the propulsion and support systems from a vehicle perspective, using results from different SHC areas and other related research. The on-going technological shift makes it very important to analyse solutions from a vehicle and user perspective, in order to maximize synergies and avoid sub optimisation. This analysis takes into account for example:
• how the vehicle used, its environment and the user preferences
• key industry requirements and prerequisites for the solutions
• synergies between different sub systems and interaction with infrastructure
