  1. 1. Battery profit optimization

    University essay from Lunds universitet/Industriell elektroteknik och automation

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

    Abstract : 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. READ MORE

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

    University essay from Högskolan Väst/Institutionen för ingenjörsvetenskap

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

    Abstract : 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. READ MORE

  4. 3. State of charge and heat impact on Li-ion batteries during calendar aging

    University essay from Uppsala universitet/Signaler och system

    Author : Martin Jonsson; Tobias Karlsson; [2023]
    Keywords : State of charge; SoC; calendar aging; heat impact; Li-ion;

    Abstract : Rechargeable batteries that are powering our everyday electronics go through their lifetime with countless charge/discharge cycles, after a few years the capacity has dropped noticeably. But how about batteries that are working as a back-up power system for when connection to the AC mains is not possible, they might only perform a handful of cycles but does this mean they last forever? On behalf of Getinge AB, this bachelor thesis aims to explore the subject named as ‘calendar aging’. READ MORE

  5. 4. Energy Storage for Stationary Applications – A Comparative, Techno-Economical Investigation

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)
