  1. 1. Suppression of Li-ion Battery Fires

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Linfan Cai; [2023]
    Keywords : Lithium-ion Battery; Fire Suppression System; Extinguishing Agent; Thermal Runaway; Battery Energy Storage System; Electric Vehicle; Technology and Engineering;

    Abstract : This thesis presents a systematic literature review of fixed fire suppression systems and extinguishing agents for lithium-ion battery (LIB) fires. The review identifies 85 relevant sources published between 2013 and March 2023, and categorises different research experiments into cell-level, module-level, electric vehicle (EV) pack-level, battery energy storage system (BESS) rack-level and warehouse storage experiments, according to LIB configurations.

  3. 2. DC-DC Converter for Fast Charging with Mobile BESS in a Weak Grid : Enabling remote charging and increased efficiency with less resource intensity

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Alexander Medén; [2023]
    Keywords : Battery energy storage systems; Buck-boost; DC DC converter; Dual-active bridge; fast charging; DC charging; Mobile battery systems; Batterienergilagringssystem; Buck-boost; DC DC-omvandlare; Dual-active bridge; snabbladdning; DC-laddning; Mobila batterisystem;

    Abstract : With the increase of electric vehicles (EVs) on the roads the availability of charging infrastructure becomes more important. Today it is relatively straightforward to install fast chargers in areas with strong power grid connections, such as in urban areas. READ MORE

  4. 3. Rotating current collector for dynamic charging of electrical vehicles

    University essay from Lunds universitet/Innovation

    Author : Linnea Romare; Alexander Bjursåker; [2022]
    Keywords : Electrification; electrical roads; dynamic charging; Elonroad; pick-up; Technology and Engineering;

    Abstract : Cutting carbon emission from road transports worldwide is a key component in limiting global warming, and electrification is one of the most likely automotive technologies to achieve this goal. Therefore, Elonroad is developing an electric road system that will allow its users to charge while driving. READ MORE

  5. 4. Using active learning for semi-automatically labeling a dataset of fisheye distorted images for object detection

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Olof Bourghardt; [2022]
    Keywords : Machine learning; Object detection; Computer vision; Semi-automatic data labeling; Fisheye images;

    Abstract : Self-driving vehicles has become a hot topic in today's industry during the past years and companies all around the globe are attempting to solve the complex task of developing vehicles that can safely navigate roads and traffic without the assistance of a driver.  As deep learning and computer vision becomes more streamlined and with the possibility of using fisheye cameras as a cheap alternative to external sensors some companies have begun researching the possibility for assisted driving on vehicles such as electrical scooters to prevent injuries and accidents by detecting dangerous situations as well as promoting a sustainable infrastructure.

  6. 5. An analysis of energy neutral roads : A case study how to produce electricity and hydrogen using thesurface area of the A6 highway in the Netherlands

    University essay from Högskolan i Gävle/Energisystem och byggnadsteknik

    Author : Chris Johan De Joode; [2022]
    Keywords : Solar roads; energy neutral roads; road energy; future demands; strategic sustainable development; electrolysing;

    Abstract : The need for renewable energy sources is evident. The worlds energy economy need to change rapidly to stopthe climatological changes. The ratio between renewables and fossil fuels, or an energy economy only based onrenewables, is based on political choices. The surface footprint of renewables is significantly larger thantraditional power plants. READ MORE
