  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. Fast charging of electrical vehicles with help from battery energy storage systems : A study of how batteries can lower the power peaks for fast charging of electrical vehicles in Stockholm

    University essay from KTH/Hälsoinformatik och logistik

    Author : Erik Wikström; [2023]
    Keywords : Electric vehicle; fast charging; direct current charging; battery energy storage system; Elfordon; snabbladdning; likströmsladdning; batterienergilagringssystem;

    Abstract : To enable fast charging of electric vehicles in Stockholm or sites where the electrical energy is limited and the number of chargeable vehicles increases, there is a need to investigate new solutions to comply with the future demand. The goal of this project is to investigate what the conditions are in Stockholm today and investigate what is needed to enable fast chargers in Stockholm city. READ MORE

  4. 3. Optimal Control of An Energy Storage System Providing Fast Charging and Ancillary Services

    University essay from KTH/Optimeringslära och systemteori
