Revizija baterijskega paketa za napajanje naprav za zajemanje podatkov

DEBEVC, MARTIN (author), Jankovec, Marko (mentor)

V tem diplomskem delu je opisan postopek predelave baterijskega paketa, ki služi napajanju naprav za zajemanje podatkov v zahtevnejših okoljih, kot je na primer povečana temperatura. Potreba po reviziji se je pojavila po tem, ko se je s trga umaknil modul, ki so ga v podjetju uporabljali do sedaj. Naša naloga je bila narediti krmilnik za polnjenje dveh baterijskih sklopov z že vgrajenim uravnovešanjem, krmilno logiko za celoten izdelek in zaščito proti prevelikemu praznilnemu toku posamezne baterije. Za dokončanje izdelka smo načrtovali celotno shemo vezij in pripravili tiskana vezja za izdelavo. Naredili smo tudi funkcionalne, temperaturne, izolativne in električno-varnostne teste v laboratoriju in tudi pravi test na motornem kolesu, s katerim smo opravili približno 60 km. Prav tako smo tudi spisali programsko kodo za mikrokrmilnik, ki krmili in nadzoruje celoten sistem. Zaradi spremembe same mehanike smo morali spremeniti in dodelati tudi aluminijasto ohišje.

Abstract

In this bachelor's degree thesis we have described a complete process of re-designing battery pack for powering DAQ devices that can operate in harsh invorement, for example increased temperature. The need for re-design came from market, because previously used batery charging controller went obsolete. Our job was, to make a controller, that will be able to charge two baterries with allready embeded balancing circuit, control logic for whole system, and overcurrent protection for each battery. One of requriment was also, that batteries are hot-swappable. For final product we have designed all the schematics, PCBs, ordered them, tested and assembled first two prototypes. We have made functional, temperature, isolation and electrical-safety (burst, surge) tests in laboratory, and we have also driven battery pack for about 60 km on the back of motorcycle. We have also written firmware, which controls whole system. Due to change in shape of PCBs we had to adapt aluminium case for the product.
