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

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Evelina Wikner; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Calendar aging; Physics-based modeling; Battery lifetime tests; Plug-in Hybrid Electric Vehicle PHEV ; Electric Vehicle EV ; Hybrid Electric Vehicle HEV ;

    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

  2. 2. Realistic Package Opening Simulations An Experimental Mechanics and Physics Based Approach

    University dissertation from Karlskrona : Blekinge Institute of Technology
