1. 21. Lithium ion Battery Aging: Battery Lifetime Testing and Physics-based Modeling for Electric Vehicle Applications

   Författare :Evelina Wikner; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Physics-based modeling; Electric Vehicle EV ; Battery lifetime tests; Hybrid Electric Vehicle HEV ; Plug-in Hybrid Electric Vehicle PHEV ; Calendar aging;

   Sammanfattning : Electrification of vehicles is one solution in reducing emissions from the transport sector, and in particular to limit tail-pipe emissions in cities. In order to make the electrification successful and cost effective, there is a high demand for longer drive range and longer battery lifetime. LÄS MER

3. 22. Life cycle assessment of electric vehicle batteries and new technologies

   Författare :Mats Zackrisson; Magnus Wiktorsson; Martin Kurdve; Christina Jönsson; Anders Nordelöf; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; life cycle assessment; LCA; electric vehicle; sustainability; eco-design; Production Engineering; Industriell produktion;

   Sammanfattning : Electrification of vehicles has for decades been explored as a possible solution to the problem of climate change. Today, in 2021, the issue is no longer whether the electrification of vehicle fleets ought to happen but rather how it can be achieved with as little environmental impact as possible. LÄS MER

4. 23. Towards a sustainable automotive industry : experiences from the development of emission control systems

   Författare :David Bauner; Staffan Laestadius; Lee Schipper; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; evolutionary economics; environmental innovation; trajectories; co-evolution; Industrial engineering and economy; Industriell teknik och ekonomi;

   Sammanfattning : From the mid-1970s and on, the contribution to air pollution of carbon monoxide, hydrocarbons and nitrogen oxides from gasoline passenger cars in the developed world has been reduced through co-evolution of regulation and commercial introduction of catalytic emission control technology, now part of hundreds of millions of cars, trucks and buses worldwide. This dissertation is a disaggregated study of the global introduction of catalytic emission control technology as a measure to reduce local air pollution. LÄS MER

5. 24. Comparison of Different Electrical Machines for Belt-driven Alternator and Starter

   Författare :Dan Hagstedt; Industriell elektroteknik och automation; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Belt-driven Alternator and Starter; Permanently Magnetised Synchronous Machine; Electrically Magnetised Synchronous Machine; Series Magnetisation Synchronous Machine; Hybrid Magnetised Synchronous Machine;

   Sammanfattning : This thesis focuses on the electromagnetic design of a synchronous machine suited for a belt-driven alternator and starter (BAS) in a micro hybridisation of a mid-size passenger car. The BAS needs to provide a high cranking torque to start the combustion engine, especially in a cool condition where the requirements are highest. LÄS MER

7. 25. Electric vehicles in action

   Författare :Martina Wikström; Per Alvfors; Lisa Hansson; Gil Tal; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electric vehicles; interdisciplinary approach; public fleets; public transport;

   Sammanfattning : This thesis analyses the political and practical conditions for introducing electric vehicles in Swedish public authorites and discusses the potential for using electric vehicles in public transport and public fleets. The work has been carried out using an interdisciplinary research approach. LÄS MER
