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

    University essay from KTH/Kemiteknik

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

    Abstract : 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. READ MORE

  3. 2. Manufacturing & Regional Cost Competitiveness of Commercial Sodium Ion Cells : A bottom-up cost analysis of Lithium and Sodium Ion Battery Storage

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

  4. 3. Low-power Acceleration of Convolutional Neural Networks using Near Memory Computing on a RISC-V SoC

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Kristoffer Westring; Linus Svensson; [2023]
    Keywords : FPGA; ASIC; Near Memory Computing; RISC-V; Convolutional Neural Network; Technology and Engineering;

    Abstract : The recent peak in interest for artificial intelligence, partly fueled by language models such as ChatGPT, is pushing the demand for machine learning and data processing in everyday applications, such as self-driving cars, where low latency is crucial and typically achieved through edge computing. The vast amount of data processing required intensifies the existing performance bottleneck of the data movement. READ MORE

  5. 4. 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

  6. 5. Battery field data-oriented investigation of cell capacity spread and its impacts

    University essay from

    Author : Muhammad Bilal; [2022]
    Keywords : Cell Capacity; Electric Vehicles; Algorithm; Current Profile; Voltage;

    Abstract : In this research thesis, a new data-centric approach is used to determine the individual cell capacities in Li-ion batteries used in electric vehicles (EVs). This approach could also be extended to batteries for static energy storage applications. READ MORE
