  1. 1. Electric vehicles in action

    Author : Martina Wikström; Per Alvfors; Lisa Hansson; Gil Tal; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; electric vehicles; interdisciplinary approach; public fleets; public transport;

    Abstract : This thesis analyses the political and practical conditions for introducing electric vehicles in Swedish public authorites and discusses the potential for using electric vehicles in public transport and public fleets. The work has been carried out using an interdisciplinary research approach. READ MORE

  2. 2. Sustainable Personal Road Transport : The Role of Electric Vehicles

    Author : Sven Borén; Göran Broman; Henrik Ny; Louise Trygg; Jamil Khan; Blekinge Tekniska Högskola; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strategic Sustainable Development; Transport Planning; Electric Vehicles; Testing; LCA;

    Abstract : Electric vehicles can play an important role in a future sustainable road transport system and many Swedish politicians would like to see them implemented faster. This is likely desirable to reach the target of a fossil independent vehicle fleet in Sweden by 2030 and a greenhouse gas neutral Swedish society no later than 2050. READ MORE

  3. 3. The Four-Quadrant Transducer System : for Hybrid Electric Vehicles

    Author : Erik Nordlund; Chandur Sadarangani; Hans Kahlen; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; Electrical Machines; Hybrid Vehicles; Elektroteknik; Electrical engineering; Elektroteknik;

    Abstract : In this thesis a hybrid electrical powertrain called the Four Quadrant Transducer (4QT) has been evaluated through different driving simulations, which later resulted in the manufacture of a prototype. The simulation of a 12 metric ton distribution truck showed that the 4QT system can reduce the fuel consumption by approximately 30 % during the FTP75 drive cycle. READ MORE

  4. 4. Diffusion of Battery Electric Vehicles : The Role of Total Cost of Ownership

    Author : Jens Hagman; Sofia Ritzèn; Johan Jansson; KTH; []
    Keywords : Total cost of ownership; electric vehicles; e-taxis; vehicle salespeople; Machine Design; Maskinkonstruktion;

    Abstract : Due to their high efficiency, zero tailpipe emissions and possibilities of using renewable electricity, Battery Electric Vehicles (BEVs) have been proposed as a way to alleviate the negative consequences of transport. However, as with other energy-efficient innovations market uptake or diffusion of BEVs have so far been limited. READ MORE

    Abstract : Both electric power systems and the transportation sector are essential constituents to modern life, enhancing social welfare, enabling economic prosperity and ultimately providing well-being to the people. However, to mitigate adverse climatological effects of emitting greenhouse gases, a rigorous de-carbonization of both industries has been set on the political agenda in many parts of the world.
