20.500.12556/DKUM-90270 Merjenje napolnjenosti dveh zaporedno vezanih Li-ionskih baterij s pomočjo mobilnega telefona diplomsko delo Measuring the state of charge of two serially connected Li-ion batteries with the help of a mobile phone Namen tega projekta je bilo ustvariti vezje, ki bo omogočalo napajanje poljubnega bremena in istočasno merjenje stanja napolnjenosti dveh zaporedno vezanih Li – ionskih baterij, ki breme napajata ter posredovanje podatkov na mobilni telefon preko Bluetooth komunikacije. Izdelano je bilo tiskano vezje, ki vključuje mikrokrmilnik za katerega je bil napisan program, ki omogoča branje napetosti na njegovih vhodih in vse potrebne izračune. Vezje in program sta od začetka delovala kot pričakovano. Vsi potrebni podatki so bili uspešno posredovani na mobilni telefon. Poleg tega je projekt vključeval tudi eksperimentalno določanje kapacitete baterij in pa večkratno analizo praznjenja, katere ugotovitve so služile za izboljšavo programa. The purpose of this project was to create a circuit that would allow the powering of an arbitrary load while simultaneously measuring the state of charge of two series-connected Li-ion batteries that power the load, and transmitting the data to a mobile phone via Bluetooth communication. A printed circuit board (PCB) was developed, which includes a microcontroller for which a program was written to read the voltage at its inputs and perform all necessary calculations. The circuit and program functioned as expected from the start. All the necessary data was successfully transmitted to the mobile phone. Additionally, the project included experimental determination of battery capacity and multiple discharge analyses, the findings of which were used to improve the program.
