20.500.12556/DKUM-85112 Merjenje napolnjenosti li-ionske baterije z mobilnim telefonom - električno vezje diplomsko delo Measuring the charge of a li-ion battery with a mobile phone - electrical circuit Diplomsko delo je osredotočeno na merjenje napolnjenosti baterij. V današnjem času vedno več naprav potrebuje baterije in kot uporabniki želimo vedeti njihovo napolnjenost, najboljše kar preko mobilne aplikacije. Sestavili smo električno vezje, s katerim merimo napolnjenost baterije. Metod je več. Uporabljena je bila metoda branja napetosti ob neki obremenitvi, v našem primeru je to elektromotor. Tok merimo preko optičnega sklopnika 6N136. Na izhodu tega čipa dobimo potrebno izhodno napetost, ki jo pripeljemo na vhod čipa BM70. Ta omogoča pretvorbo iz analognega v digitalni signal, ki se prenese preko Bluetooth komunikacije na mobilni telefon. Program na mobilnem telefonu nam ovrednoti in pokaže podatke, kot je napolnjenost baterije. This thesis is focused on a very common need of today's society, which is surrounded by rechargeable batteries of all shapes and sizes. As users, we want to know the state of charging, preferably through a mobile phone. We created an electric circuit with which we measured the charge of a battery. There are several methods for such measurement. We used the method of reading the voltage under some load, in our case an electric motor. The current is measured via an optocoupler 6N136. At the output of this chip, we get the necessary output voltage, which we bring to the input of the BM70 chip. This chip provides the conversion from analogue to digital signal. The digital signal is transmitted via Bluetooth communication to the mobile phone. On a smartphone, the program evaluates and shows the data, such as the charge of a battery. napolnjenost baterija Bluetooth Charging battery Bluetooth true true false [A.
