    Prevádzková bezpečnosť bezpilotných prostriedkov s elektrickým pohonom
    (University of Žilina, 2024) Kalafut, Lukáš; Kandera, Branislav
    The increasing adoption of electrically powered unmanned aerial vehicles (UAVs) has raised concerns about their operational safety, particularly with regards to battery technology. Lithium-based batteries, commonly used in UAVs, pose unique safety challenges due to their potential for thermal runaway, overcharging, and physical damage. The aim of this paper is to investigate the operational safety of electrically powered UAVs, with a particular focus on their battery systems. Theoretical part discusses basic types of UAVs, their electric propulsion system and the different types of batteries used in UAVs, in particular their advantages and disadvantages as well as their composition. Then, the paper also briefly explores and introduces BMS technology and its functions. In the last section of this paper, we look at the principles and practices of proper battery handling.

    Batérie druhej životnosti a systém správy batérií

    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.
