  1. 1. BEV Powertrain Component Sizing With Respect to Performance, Energy Consumption and Driving Patterns

    Författare :Emma Grunditz; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sizing; Battery Electric Vehicle; energy consumption;

    Sammanfattning : In this thesis, various drive cycles, legislative, official real-world and measured withinthe frame of the project, have been studied and characterized in terms of speed and accelerationcycle parameters, as well as acceleration and speed distribution. The objective was toassess typical vehicle usage on different road types, but also to study the implication on vehicleenergy consumption due to the drive cycle’s characteristics. LÄS MER

  3. 2. Optimal Powertrain Dimensioning and Potential Assessment of Hybrid Electric Vehicles

    Författare :Nikolce Murgovski; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; powertrain sizing; plug-in slide-in HEV; Dynamic Programming; convex optimization; Hybrid electric vehicle; power management;

    Sammanfattning : Hybrid electric vehicles (HEVs), compared to conventional vehicles, complement the traditional combustion engine with one, or several electric motors and an energy buffer, typically a battery and/or an ultracapacitor. This gives the vehicle an additional degree of freedom that allows for a more efficient operation, by e.g. LÄS MER

  4. 3. Design and Assessment of Battery Electric Vehicle Powertrain, with Respect to Performance, Energy Consumption and Electric Motor Thermal Capability

    Författare :Emma Grunditz; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy consumption; Battery Electric Vehicle; sizing;

    Sammanfattning : In this thesis, various drive cycles, legislative, official real-world and measured, have been studied and characterized based on their speed and acceleration content. Three reference vehicles (a City car, a Highway car and a Sport car) were conceptualized after performance requirements, with data on existing battery electric cars as a frame of reference. LÄS MER

  5. 4. Centrifugal pendulum vibration absorbers in heavy-duty truck powertrains : Modelling, simulation and experimental investigations

    Författare :Erik Gomez; Leif Kari; Ines Lopez Arteaga; Ole Balling; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; centrifugal pendulum vibration absorber CPVA ; powertrain; heavy-duty truck; driveline; transmission; Vehicle and Maritime Engineering; Farkostteknik;

    Sammanfattning : The heavy-duty vehicle industry is facing big challenges to reduce CO2 emissions. Although electrification is on the rise, the combustion engine will used for some time to come. LÄS MER

  7. 5. A Methodology for the Design of Cost Effective Hybrid Vehicles

    Författare :Jonas Hellgren; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fuzzy logic; system engineering; model car; optimal design; evolutionary algorithms; hybrid electric vehicle; alternative powertrain; simulation; modeling; genetic algorithms; fuel cell vehicle; hybrid vehicle;

    Sammanfattning : This thesis deals with system design of cost effective hybrid and fuel cell vehicles. Today (2004) the major disadvantages of these vehicles are increased complexity and component costs. However, the decrease in cost of electrical components and the environmental concern make these vehicles more and more competitive. LÄS MER
