20.500.12556/DKUM-73170 Načrtovanje in izdelava laboratorijskega testerja baterij Designing and manufacturing a laboratory battery tester V magistrskem delu je opisan postopek načrtovanja in izdelave laboratorijskega sistema za testiranje (testerja) baterij. Osrednji del testerja je razvojna plošča podjetja Texas Instruments. Slednja krmili nastavljivo breme in omejevalnik polnilnega toka, izveden z MOSFET tranzistorji. Za izdelavo testerja baterij so bile najprej izbrane komponente za celoten sistem. V programu LTspice je bila narejena simulacija ciklanja baterije z uporabo izbranih komponent, nato je bilo dizajnirano še tiskano vezje. Programska koda je bila sestavljena v Simulinku, ki je dodatek programskega paketa Matlab. Končan tester baterij je bil pregledan s termovizijsko kamero, nato so bili pri različnih tokih preizkušeni načini ciklanja, praznjenja in polnjenja baterij. This Master's thesis describes the process of designing and manufacturing a laboratory battery tester. The main part of the tester is a development board, made by Texas Instruments. It controls MOSFET transistors, which are used as an electronic load as well as an input current limiter. Before designing the battery tester, components were carefully selected. A simulation of cycling a battery was performed in a program LTspice, using the selected components. After that a PCB was designed. The program code was prepared in Matlab's component Simulink. The finished battery tester was checked with a thermal camera, followed by testing its cycling, charge and discharge modes at different currents. testiranje baterij elektronsko breme regulacija toka ciklanje baterij litijeve baterije battery testing electric load current control battery cycling lithium batteries true true false Č.
