  2. 1. Energy Consumption and Running Time for Trains : modelling of running resistance and driver behaviour based on full scale testing

    Author : Piotr Lukaszewicz; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy consumption; Running time; running resistance; driver behaviour; freight; train; energy coasting method; aerodynamic drag; driver model; degree of coasting; slippage; wind; Energy saving; braking ratio; powering ratio; full scale testing; Vehicle engineering; Farkostteknik;

    Abstract : The accuracy in determined energy consumption and runningtime of trains, by means of computer simulation, is dependent upon the various models used. This thesis aims at developing validated models of running resistance, train and of a generaldriver, all based on full scale testing. READ MORE

  4. 2. On power loss minimisation for heavy vehicles with axle-wise and modular electrical propulsion and friction braking

    Author : Sachin Janardhanan; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; friction brakes; powertrain; power loss; electric machines; Heavy vehicles; topology;

    Abstract : The main challenges for battery electric heavy vehicles are improving the payload capacity and driving range for different applications. These are mainly influenced because of battery power density, different vehicle configurations, and powertrain design. READ MORE

  5. 3. Assessment of PHEV potential to reduce fuel use in Sweden using GPS data for car movements

    Author : Lars Henrik Björnsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PHEV potential; battery size; GPS-logging; PHEV viability; PHEV; Sweden; electrification; Individual movement pattern;

    Abstract : Roughly 30% of Sweden’s total greenhouse gas emissions originate from transport. These emissions need to be reduced to be able to reach the by The Swedish parliament adopted goal of a carbon neutral society in 2050. READ MORE

  6. 4. Optimization of Plug-in Hybrid Electric Vehicles

    Author : Mitra Pourabdollah; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The rising concerns about the global warming and emissions on one hand,and the limited resources of fossil fuels on the other hand, have made electrificationof vehicles a necessary topic among researchers and companies.Hybrid electric vehicles (HEV), which in addition to a primary power source,such as internal combustion engine or fuel cell, have an electric motor andan electric energy storage, such as a battery, have proved to decrease thefuel consumption.
