  1. 1. High Performance Cooling of Traction Brushless Machines

    Author : Alessandro Acquaviva; Chalmers University of Technology; []
    Keywords : energy efficiency; electrical machine design; Cooling; drivetrain system analysis.; permanent magnet synchronous machine PMSM ;

    Abstract : The work presented in this thesis covers several aspects of traction electric drive system design. Particular attention is given to the traction electrical machine with focus on the cooling solution, thermal modelling and testing. READ MORE

  2. 2. On design and analysis of synchronous permanent magnet machines for field-weakening operation in hybrid electric vehicles

    Author : Freddy Magnussen; Chandur Sadarangani; Barrie Mecrow; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Applied mechanics; permanent magnet machines; field-weakening; hybrid electric vehicles; soft magnetic composites; fractional pitch concentrated windings; Teknisk mekanik; Engineering mechanics; Teknisk mekanik;

    Abstract : A regular vehicle of today is equipped with an internal combustion engine that runs on either gasoline or diesel, which are fossil fuels from oil reserves that are millions of years old. In all types of combustion processes carbon dioxide and several other emissions are produced. READ MORE

  3. 3. Vehicle Dynamic Opportunities in Electrified Vehicles for Active Safety Interventions

    Author : Adithya Arikere; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rear-end collisions; active safety; vehicle dynamics; obstacle avoidance with oncoming traffic; speed control; electrified drivetrain; torque vectoring; driver assistance systems;

    Abstract : Although the sales of electrified vehicles is growing, studies indicatethat the growth is inadequate to sufficiently reduce CO2 emissions andmitigate global warming. Some form of added incentive is needed to driveelectrified vehicle sales. READ MORE

  4. 4. Vehicle Dynamics Control for Active Safety Functions using Electrified Drivelines

    Author : Adithya Arikere; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; driver assistance systems; intersection accidents; torque vectoring; optimal control; rear- end collisions; speed control; active safety; vehicle dynamics; electrified drivetrain; obstacle avoidance with oncoming traffic;

    Abstract : Studies have shown that even considering pledges and commitments made by various governments and organisations, the growth in electrified vehicle sales is likely to be insufficient to reduce CO2 emissions for mitigating global warming. Some form of added incentive is needed that can help drive electrified vehicle sales in the open market. READ MORE

  5. 5. Interactions between battery and power electronics in an electric vehicle drivetrain

    Author : Alexander Bessman; Göran Lindbergh; Pontus Svens; Oskar Wallmark; Torbjörn Thiringer; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Engineering; Kemiteknik; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The electric machine and power electronics in electric and hybrid electric vehicles inevitably cause AC harmonics on the vehicle's DC-link. These harmonics can be partially filtered out by large capacitors, which today are overdimensioned in order to protect the vehicle's battery pack. READ MORE
