  1. 21. Towards Low-Voltage, High-Current : A pioneering drive concept for battery electric vehicles

    Författare :Stefan Haller; Kent Bertilsson; Bengt Oelmann; Peng Cheng; Dieter Gerling; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; low voltage; high current; EV; BEV; electrical machine; power electronics; MOSFET;

    Sammanfattning : The first electric low-voltage vehicles were constructed in the mid-19th century, but by the early 20th century they were progressively replacedby successors with internal combustion engines. As the consequences ofusing fossil fuels are better understood, our society is now transitioning back. LÄS MER

  3. 22. Analysis and Control Aspects of a PMSynRel Drive in a Hybrid Electric Vehicle Application

    Författare :Shuang Zhao; Chandur Sadarangani; Zi-Qiang Zhu; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active damping control; electric drive; electric vehicle; hybrid electric vehicle; integrated charger; permanent-magnet assisted synchronous reluctance machine; position estimation; sensorless control;

    Sammanfattning : This thesis deals withmodeling and control of an electric drive equipped with a permanentmagnet assisted synchronous reluctance (PMSynRel) machine for a plug-in hybrid electric vehicle application.In the first part of the thesis, a special use of the PMSynRel machine in consideration, known as an integrated charger concept, is investigated.

  4. 23. Thermal and State-of-Charge Balancing of Batteries using Multilevel Converters

    Författare :Faisal Altaf; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal balancing; Convex optimization; DC-link ripple; Battery ripple; Battery control; Hybrid electric vehicles.; Multilevel converter; Cell balancing;

    Sammanfattning : Driven by the needs to reduce the dependence of fossil fuels and the emissions of conventional vehicles there has in recent years been an increasing interest in battery-powered electrified vehicles (xEVs). In xEVs, the battery pack, built from many small cells, is one of the most expensive components in the powertrain. LÄS MER

  5. 24. On Optimization of Plug-in Hybrid Electric Vehicles

    Författare :Mitra Pourabdollah; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EnergyManagement; ECMS; Plug-in Hybrid Electric Vehicles; Driving Cycles.; Component Sizing;

    Sammanfattning : The rising concerns about the global warming and emissions on one hand, and the limited sources of fossil fuels on the other hand, has made electrificationof vehicles an interesting topic among researchers and companies. Hybrid electric vehicles (HEV) have been on market or several years. LÄS MER

  7. 25. Design, Modelling and Verification of Distributed Electric Drivetrain

    Författare :Nimananda Sharma; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electric vehicles; system modelling; mechanical-hardware-in-the-loop; real-time modelling; power-hardware-in-the-loop; Distributed drivetrain;

    Sammanfattning : The electric drivetrain in a battery electric vehicle (BEVs) consists of an electric machine, an inverter, and a transmission. The drivetrain topology of available BEVs, e.g., Nissan Leaf, is centralized with a single electric drivetrain used to propel the vehicle. LÄS MER
