  1. 1. Battery profit optimization

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Ebba Helfer; [2023]
    Nyckelord :Battery; 2nd life battery; Ancillary services; BESS; energy storage system; Technology and Engineering;

    Sammanfattning : In the near future, a new market will form full of 2nd life batteries that are no longer suitable to use in electric vehicles. This since their capacity retention is too low after a few years of usage, as a consequence of two aging mechanisms; cycling aging and calendar aging. LÄS MER

  3. 2. Second Life Applications for Degraded EV Batteries : Evaluating Benefits Basedon Remaining Useful Life and Battery Configurations

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Sandberg Elis; [2023]
    Nyckelord :;

    Sammanfattning : This thesis explores the potential of second-life electric vehicle batteries, which are no longer suitable for electro-mobility, to provide energy storage solutions. The study iden- tifies two potential applications for second-life batteries: charging stations and residential PV energy storage systems. LÄS MER

  4. 3. Hardware Subsystem Proposal of an Off-Vehicle Battery Analyzer from a Charging/Discharging Perspective

    Kandidat-uppsats, Högskolan Väst/Institutionen för ingenjörsvetenskap

    Författare :Rinor Gashi; Tim Johansson; [2023]
    Nyckelord :battery electric vehicles; power conversion module; off-vehicle battery packs;

    Sammanfattning : Electric Vehicles (EVs) are seen as one of the solutions to some of the world’s global current problems, such as global warming and air pollution, due to non-existent operational emissions and increased efficiency. There are multiple types of EVs, one of them being Battery Electric Vehicles (BEVs) which in most cases utilizes a Li-Ion battery pack as energy storage. LÄS MER

  5. 4. Pulse Charging of Li-ion Batteries for Enhanced Life Performance

    Master-uppsats, KTH/Kemiteknik

    Författare :Josefin Strandberg; [2023]
    Nyckelord :Li-ion battery; Pulse charging; Cyclic aging; Capacity fade; Internal resistance; Battery impedance; Litiumjonbatteri; Pulsad laddning; Cyklisk åldring; Kapacitetsminskning; Inre resistans; Batteriimpedans;

    Sammanfattning : Det överhängande behovet av att minska utsläppen av växthusgaser för att uppfylla Parisavtalet har väckt ett ökat intresse för elektrifiering som en strategi för att mildra klimatförändringarna. Litiumjonbatterier spelar en central roll vid elektrifiering och har framträtt som det primära alternativet för batteridrivna elfordon. LÄS MER

  7. 5. Battery Capacity Prediction Using Deep Learning : Estimating battery capacity using cycling data and deep learning methods

    Uppsats för yrkesexamina på avancerad nivå, Mälardalens universitet/Framtidens energi
