1. 6. Experimental investigations of ageing of commercial BEV Li-ion batteries

   Författare :Kristian Bartholdsson Frenander; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; silicon oxide; lithium plating; ageing; Physics-based modelling; Electric Vehicles; Lithium Ion Batteries; lifetime; NCA; State of Charge;

   Sammanfattning : The rapid development of lithium-ion batteries has enabled changes in widespread applications ranging from portable electronics to electric vehicles and large scale grid energy storage. However, battery ageing remain a challenge in all these applications, and this thesis seeks to contribute to the understanding of Li-ion battery degradation. LÄS MER

3. 7. BEV Powertrain Component Sizing With Respect to Performance, Energy Consumption and Driving Patterns

   Författare :Emma Grunditz; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sizing; Battery Electric Vehicle; energy consumption;

   Sammanfattning : In this thesis, various drive cycles, legislative, official real-world and measured withinthe frame of the project, have been studied and characterized in terms of speed and accelerationcycle parameters, as well as acceleration and speed distribution. The objective was toassess typical vehicle usage on different road types, but also to study the implication on vehicleenergy consumption due to the drive cycle’s characteristics. LÄS MER

4. 8. Automotive Remanufacturing in a Changing Market : Challenges and Opportunities in a market with a growing share of electric cars

   Författare :Robert Casper; Erik Sundin; Mats Björkman; Amir Rashid; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Circular Economy; Remanufacturing Process Challenges and Improvements; Process Efficiency; Automotive Part Remanufacturing and Reuse; Internal Combustion Engines ICE ; Battery Electric Vehicles BEV ; Cirkulär Ekonomi; Återtillverkning; Återtillverkningsprocesser; Processeffektivitet; Bilindustri; Förbränningsmotorer; Elbilar; Elektrifiering;

   Sammanfattning : This doctoral thesis deals with closed-loop supply chains, which include remanufacturing. Remanufacturing can be described as an industrial process to bring back a used good into an “as-good-as-new” condition. Furthermore, focus is put on one of the largest global industry sectors: the automotive industry. LÄS MER

5. 9. A targeted approach to maintenance of tumour response. Clinical and translational studies in metastatic colorectal cancer

   Författare :Helga Hagman; Tumörmikromiljö; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; kolorektal cancer; underhållsbehandling; biomarkörer; angiogeneshämning;

   Sammanfattning : In metastatic colorectal cancer (mCRC) chemotherapy +/- targeted therapy with palliative intent aims at prolonging survival with sustained quality of life. Maintenance of tumour response by a period of less intense treatment maydelay progression and accumulation of unacceptable toxicity. LÄS MER

7. 10. Cost and financing of the sustainability transition of the Swedish road freight transport sector

   Författare :Elmira Parviziomran; Göteborgs universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Godstransporter; Hållbar utveckling; Fossila bränslen; Fordon; Kostnader; Finansiering; Batterier; Sustainable development; Electric batteries; Vehicles; Freight and freightage; Fossil fuels; Sustainability transition; Decarbonization; Heavy-duty vehicles; Cost; Financing; Battery; Circular economy; Diesel fuels;

   Sammanfattning : The cost and financing of the road freight sector’s sustainability transition, driven by significant greenhouse gas (GHG) emissions and cost considerations, represent an urgent yet underexplored research focus. This study investigates the costs of fleet replacement with zero-emission powertrains, battery electric vehicles (BEVs) and fuel cell vehicles (FCVs), emphasizing cost variables that have been overlooked in transition research.
