  1. 1. Investigation of a Multilevel Inverter for Electric Vehicle Applications

    Author : Oskar Josefsson; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Plug-in Electric Vehicle PEV ; Electric Vehicle EV ; LiFePO4.; Integrated Charger; Efficiency; Drive Cycle; Battery modelling; Multilevel Inverter MLI ; Two-level Inverter TLI ;

    Abstract : Electrified vehicles on the market today all use the classical two-level inverter as the propulsion inverter. This thesis analyse the potential of using a cascaded H-bridge multilevel inverter as the propulsion inverter. READ MORE

  2. 2. Lithium ion Battery Aging: Battery Lifetime Testing and Physics-based Modeling for Electric Vehicle Applications

    Author : Evelina Wikner; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Calendar aging; Physics-based modeling; Battery lifetime tests; Plug-in Hybrid Electric Vehicle PHEV ; Electric Vehicle EV ; Hybrid Electric Vehicle HEV ;

    Abstract : Electrification of vehicles is one solution in reducing emissions from the transport sector, and in particular to limit tail-pipe emissions in cities. In order to make the electrification successful and cost effective, there is a high demand for longer drive range and longer battery lifetime. READ MORE

  3. 3. Energy Efficiency Comparison Between Two-level and Multilevel Inverters for Electric Vehicle Applications

    Author : Oskar Josefsson; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electric Vehicle EV ; Drive Cycle; Plug-in Electric Vehicle PEV ; Multilevel Inverter MLI ; Two-level Inverter TLI ; Efficiency.; Integrated Charger;

    Abstract : In order to contribute to the development of energy and cost efficient electric vehicles, a thorough analysis of two different electric converter topologies is performed, considering different drive cycles and different control strategies. In the electric vehicles available on the market today, a high voltage (200−400 V ) battery pack composed of several battery modules is connected to one or more inverters which create AC voltages to the electric propulsion machines.

  4. 4. Improving energy-efficiency of electric vehicles by over-actuation : Du som saknar dator/datorvana kan kontakta [email protected] för information

    Author : Peikun Sun; Annika Stensson Trigell; Lars Drugge; Jenny Jerrelind; Gordon Timothy; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Farkostteknik; Vehicle and Maritime Engineering;

    Abstract : As the concerns regarding environmental pollution, climate change and the fossilfuel crisis have grown, electric vehicles (EVs) have attracted a great deal of attention. However, for EVs to be more competitive compared with internal combustion engine vehicles (ICEVs), their driving range needs to be increased. READ MORE

  5. 5. Impact on the Distribution System due to Plug-In Electric Vehicles and Changes in Electricity Usage

    Author : David Steen; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Plug-in hybrid electric vehicle PHEV ; Electric vehicle EV ; Plug-in Electric Vehicle PEV ; Open loop radial distribution system; Electrical distribution system; Load management;

    Abstract : Replacing conventional vehicles by Plug-in Electric Vehicles (PEVs) would likely increase electricity demand and put higher stress on the electrical power system. This thesis presents an approach to evaluate the impact on electrical distribution systems (DSs) caused by charging PEVs and load management of heating loads. READ MORE
