20.500.12556/DKUM-91864 Delovanje in učinkovitost solarnega električnega pastirja z natrij-ionsko baterijo magistrsko delo Operation and efficiency of a solar powered electric fence energizer with a sodium-ion battery Magistrska naloga obravnava delovanje in izkoristek solarnega električnega pastirja z natrij-ionsko baterijo. Solarni električni pastirji so naprave, ki se uporabljajo za odvračanje živali od dotikanja ograje z električnim sunkom. Tradicionalno se napajajo s pomočjo svinčevo-kislinskih baterij in PWM solarnih regulatorjev. V tem delu smo raziskali možnost uporabe natrij-ionskih baterij in MPPT solarnih regulatorjev za izboljšanje izkoristka solarnih električnih pastirjev. V teoretičnem delu smo predstavili osnovne principe delovanja solarnih električnih pastirjev, prednosti in slabosti uporabe natrij-ionskih baterij ter delovanje MPPT regulatorja. V eksperimentalnem delu smo zgradili prototip solarnega električnega pastirja z natrij-ionsko baterijo in MPPT regulatorjem ter ga primerjali s tradicionalnim sistemom z GEL baterijo in PWM regulatorjem. Meritve so vključevale izkoristek polnjenja baterij, izkoristek regulatorja in izkoristek generatorja visokonapetostnega pulza. Rezultati so pokazali, da je sistem z natrij-ionsko baterijo in MPPT regulatorjem dosegel višji izkoristek polnjenja baterij in višji izkoristek regulatorja v primerjavi s tradicionalnim sistemom. Izkoristek generatorja visokonapetostnega pulza je bil pri obeh sistemih primerljiv. Ugotovili smo, da uporaba natrij-ionskih baterij in MPPT regulatorja lahko izboljša učinkovitost solarnih električnih pastirjev. Natrij-ionske baterije so se izkazale za bolj učinkovite pri shranjevanju energije, MPPT regulator pa je omogočil boljše izkoriščanje sončne energije. This master's thesis examines the operation and efficiency of a solar-powered electric fence with a sodium-ion battery. Solar-powered electric fences are devices used to deter animals from touching a fence by delivering an electric shock. Traditionally, they are powered by lead-acid batteries and PWM solar charge controllers. In this work, we explored the possibility of using sodium-ion batteries and MPPT solar charge controllers to improve the efficiency of solar-powered electric fences. In the theoretical part, we presented the basic operating principles of solar-powered electric fences, the advantages and disadvantages of using sodium-ion batteries, and the operation of MPPT charge controllers. In the experimental part, we built a prototype solar-powered electric fence with a sodium-ion battery and MPPT charge controller and compared it with a traditional system with a GEL battery and PWM charge controller. The measurements included the efficiency of battery charging, the efficiency of the charge controller, and the efficiency of the high-voltage pulse generator. The results showed that the system with the sodium-ion battery and MPPT charge controller achieved higher battery charging efficiency and higher charge controller efficiency compared to the traditional system. The efficiency of the high-voltage pulse generator was comparable in both systems. We concluded that the use of sodium-ion batteries and MPPT charge controllers can improve the efficiency of solar-powered electric fences. Sodium-ion batteries proved to be more efficient in storing energy, while the MPPT charge controller enabled better utilization of solar energy solarni električni pastir natrij-ionska baterija MPPT regulator izkoristek solar-powered electric fence generator sodium-ion battery MPPT charge controller efficiency true true false [B.
