  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. Applications and competitiveness of redox flow batteries : Explotation of battery energy systems

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Gustav Svenningsson; Stefan Ninković; [2023]
    Keywords : ;

    Abstract : The world is going through a sustainability transition and the energy market is a crucial part for enabling its success. Currently the trend is to transition towards intermittent sources which would make the energy system more volatile and/or unreliable. READ MORE

  5. 4. Low-Power Global Time Synchronization for the Contiki-NG Operating System

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Arnis Gustins; [2023]
    Keywords : ;

    Abstract : Time synchronization is a well-known problem in low-power embedded wireless networks. While many synchronization protocols exist, usually they are not standard-compliant or do not provide synchronization of a global calendar time which is required by many applications, such as event correlation and certificate validation.

  6. 5. 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
