20.500.12556/DKUM-94298 Razvoj baterije e.leisure s termičnimi elementi diplomsko delo E.leisure battery development with thermal elements Magistrsko delo obravnava razvoj litij-železo-fosfatne baterije (LiFePO₄) E. Leisure s poudarkom na integraciji grelnih elementov za izboljšanje delovanja pri nizkih temperaturah. Namen raziskave je bil oblikovati funkcionalni prototip baterije, ki bo podjetju TAB d. d. omogočil nadaljnji razvoj in vpeljavo v serijsko proizvodnjo. V delu je podrobno predstavljeno delovanje Li-ion celic, sistem toplotnega upravljanja ter analiza konkurenčnih baterij in grelcev. Razvit je bil 3D CAD model baterijskega paketa s konfiguracijo 4S1P in integriranim ogrevanjem. Opravljena je bila tehnično-ekonomska primerjava ročne in delno avtomatizirane proizvodnje ter določitev točke preloma za investicijsko odločitev. Delo temelji na praktičnem sodelovanju s podjetjem TAB, kar prispeva k neposredni uporabnosti rezultatov. The master's thesis focuses on the development of the E. Leisure lithium iron phosphate (LiFePO₄) battery with integrated heating elements to enhance performance in low-temperature environments. The goal of the research was to design a functional battery prototype tailored to the needs of the company TAB d.d., serving as a basis for further development and potential mass production. The thesis presents a detailed overview of Li-ion cell operation, thermal management systems, and a comparative analysis of competing batteries and heating solutions. A 3D CAD model of a 4S1P battery pack with integrated heating was developed. A techno-economic comparison of manual versus semi-automated production lines was conducted, along with a break-even analysis to support strategic investment decisions. The project was carried out in collaboration with TAB d.d., ensuring practical relevance and applicability of the results.
