1. 6. An Interactive Traction Motors Design and Selection Software

   Författare :Hasan El Hinaoui-Hamze; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CAD; Access; Electric Drives; Visual Basic; Internal Combustion Engines ICEs ; · Electric Motors EMs ; SQL; MATLAB; Hybrid Electric Vehicles HEVs ; Traction Motors; MagNet;

   Sammanfattning : Use of electric motors in vehicle traction, in fact, predates the internal combustion engines (ICEs). Electric vehicles powered by dc motors were known as far back as 1890. Compared with vehicles powered by ICEs, the main drawback of the early electric vehicles was, and still is, their limited range and long recharging time. LÄS MER

3. 7. Optimal Control of Electrified Powertrains

   Författare :Martin Sivertsson; Lars Eriksson; Giorgio Rizzoni; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optimal Control; Diesel-Electric; Hybrid Electric Vehicles;

   Sammanfattning : Vehicle powertrain electrification, i.e. combining the internal combustion engine (ICE) with an electric motor (EM), is a potential way of meeting the increased demands for efficient and low emission transportation, at a price of increased powertrain complexity since more degrees of freedom (DoF) have been introduced.

7. 10. Analysing hybrid drive system topologies

   Författare :Karin Jonasson; Industriell elektroteknik och automation; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : In this thesis a simulation model is presented that enables a comparison of different hybrid topologies, with respect to fuel consumption, emissions and performance. The obtained results stress the properties of the different topologies and form a foundation for the choice of hybrid topology. LÄS MER
