    Návrh experimentálneho pracoviska pre testovanie a výskum činnosti batériového úložiska
    (University of Žilina, 2023) Kolková, Zuzana; Matušov, Jozef; Zubo, Augustín; Stupka, Aleš; Jandík, Jan
    The comprehensive experimental facility for battery storage introduces an innovative approach to analysing and optimizing the performance of energy storage systems. Designed with consideration for energy flow and overall capacity, it utilizes testing of key components such as batteries with a battery management system and power inverters. The facility, housed in two standard 20ft freight containers, not only enables efficient testing but also offers advantages in terms of cost-effectiveness, customization, mobility, and the possibility of parallel tests. The containers also serve as laboratory cells, providing an isolated environment for precise experiments. The division of the container into three main sections - power, control, and testing - brings a systematic approach to experiments with a focus on safety features. Implemented fire barriers and resilient windows ensure a secure environment for the development and testing of battery storage, contributing to the advancement of modern energy technologies.

    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.
