  2. 21. Structural Composite Lithium-Ion Battery : Effect of Intercalation induced volumetric changes on micro-damage

    Author : Johanna Xu; Janis Varna; Andrejs Pupurs; Göran Lindbergh; Kenneth Runesson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera kompositmaterial; Polymeric Composite Materials;

    Abstract : The quest for lighter materials and structures to reduce climate impacts in the automotive industry has paved the way for multifunctional solutions. Mass saving on a system level can be achieved by materials or structures having more than one primary function, thus reducing the number of components used. READ MORE

  4. 22. Wind Power and Natural Disasters

    Author : Jon Olauson; Mikael Bergkvist; Stefan Ivanell; Uppsala universitet; []
    Keywords : Wind power; Natural disasters; Hybrid energy system; Meteorological model; Statistical model; Variability; Wind power integration;

    Abstract : Wind power can be related to natural disasters in several ways. This licentiate thesis gives some background and introduces four papers devoted to two aspects of this relation. The first section looks into how small-scale wind energy converters (WECs) could be used to generate power after a natural disaster. READ MORE

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

    Author : Evelina Wikner; Chalmers tekniska högskola; []
    Keywords : 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;

    Abstract : 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. READ MORE

  6. 24. Interpretable Battery Lifetime Prediction Using Early Degradation Data

    Author : Huang Zhang; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; interpretable machine learning; uncertainty quantification; lithium-ion battery; lifetime early prediction; capacity knee;

    Abstract : Battery lifetime prediction using early degradation data is crucial for optimizing the lifecycle management of batteries from cradle to grave, one example is the management of an increasing number of batteries at the end of their first lives at lower economic and technical risk. In this thesis, we first introduce quantile regression forests (QRF) model to provide both cycle life point prediction and range prediction with uncertainty quantified as the width of the prediction interval.

  7. 25. On Battery Electric Vehicles: Driving Patterns, Multi-Car Households and Infrastructure

    Author : Niklas Jakobsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; BEV; battery size; individual movement pattern.; Electro-mobility; GPS-logging;

    Abstract : The transportation sector is responsible for a quarter of all greenhouse gas emissions in Europe. Though the transport system may be difficult to change into a less polluting system, electric vehicles may be a possible approach. READ MORE
