    Batérie druhej životnosti a systém správy batérií
    (University of Žilina, 2023) Šuňal, Martin; Kopčan, Jaroslav; Benka, Denis; Kulhánek, Tomáš; Jandík, Jan
    As electromobility continues to advance, there is a growing production of batteries that will eventually require recycling. One potential recycling approach involves repurposing worn yet still operational batteries in energy storage systems, providing them with a renewed functionality. Every battery assembly mandates a Battery Management System (BMS) to ensure proper and secure functionality. In the case of recycled cells, the BMS system becomes more intricate due to notable disparities in wear and, consequently, in parameters among the cells. Hence, active balancing of each cell within the assembly becomes imperative in such a setup. Furthermore, enhanced safety precautions are essential for such assemblies. The entire system must be scalable and adaptable to different numbers and configurations of battery cells from electric vehicles of various manufacturers.

    Vybrané problémy hasičských jednotiek pri zdolávaní požiarov elektromobilov
    (University of Žilina, 2023) Konárik, Milan; Ballay, Michal; Svetlík, Jozef; Kalužník, Dávid
    The article deals with the topic of electric cars. In the introductory part, the development of the number of electric powered assenger vehicles within the European Union and the Slovak Republic is analyzed. The main part of the article is the assessment of the available material and technical equipment of fire brigades in responding to an electric car fire. These unforeseen circumstances are a new challenge for fire brigades, characterized by the difficulty of response activities. The firefighting equipment and gear of the firefighting units are designed to be a safe and effective way of extinguishing electric vehicle fires. The article points to new means available to firefighting units in the event of these fires.
