  1. 36. On the Performance of Long-Range Autonomous Underwater Vehicles : Enhancing the Endurance of AUVs

    Författare :Clemens Deutsch; Jakob Kuttenkeuler; Roger Berg; Martin Ludvigsen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Autonomous underwater vehicles; Underwater gliders; Propulsion; Fuel cell; Energy management strategies; Autonom undervattensfarkost; Undervattensglidning; Propulsion; Bränslecell; Energy Management Strategies; Vehicle and Maritime Engineering; Farkostteknik;

    Sammanfattning : Autonomous underwater vehicles (AUVs) are robotic platforms that are commonly used to gather environmental data, provide bathymetric images, and perform manipulation tasks. These robots are used not only for scientific, but also for industrial and military purposes. LÄS MER

  3. 37. Motion modelling and control strategies of over-actuated vehicles

    Författare :Johannes Edrén; Annika Stensson Trigell; Jenny Jerrelind; Mats Jonasson; Dongpu Cao; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : With the growing concern for environmental change and uncertain oil resources, the development of new vehicle concepts will in many cases include full or partial electric propulsion. The introduction of more advanced powertrains enables vehicles that can be controlled with a variety of electric actuators, such as wheel hub motors and individual steering. LÄS MER

  4. 38. On Auxiliary Systems in Commercial Vehicles

    Författare :Christian Andersson; Industriell elektroteknik och automation; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Miljöteknik; simalation model; auxiliary system; vehicle; hybrid driveline; Road transport technology; Vägtransportteknik; pollution control; Environmental technology; kontroll av utsläpp; Energy research; Energiforskning;

    Sammanfattning : As more and more focus is put on the environmental questions and the request for cleaner transportation the demand on the vehicles increases. Especially the environmental request of the public transportation that is visible to the public and operates in the centre of the city. The demand on the buses used for public transportation will increase. LÄS MER

  5. 39. Flywheel in an all-electric propulsion system

    Författare :Johan Lundin; Hans Bernhoff; P-O Västeräng; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flywheel; electric vehicle; hybrid vehicle; power management; energy storage;

    Sammanfattning : Energy storage is a crucial condition for both transportation purposes and for the use of electricity. Flywheels can be used as actual energy storage but also as power handling device. Their high power capacity compared to other means of storing electric energy makes them very convenient for smoothing power transients. LÄS MER

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

    Författare :Evelina Wikner; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Physics-based modeling; Electric Vehicle EV ; Battery lifetime tests; Hybrid Electric Vehicle HEV ; Plug-in Hybrid Electric Vehicle PHEV ; Calendar aging;

    Sammanfattning : 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. LÄS MER
