Abstract

U ovom diplomskom radu su istraženi načini rada, konfiguracije i dijelovi baterija, litij-ionskih ćelija te sustava za upravljanje baterijskim paketom (eng. Battery Management System, BMS). Također je projektiran vlastiti BMS sustav koji se sastoji od BMS slave uređaja (za kojeg je projektirana tiskana pločica u programu Altium Designer), BMS master uređaja (korištena je STM32 Nucleo-144 razvojna pločica za koju je razvijena programska potpora temeljena na operacijskom sustavu za rad u stvarnom vremenu FreeRTOS) te komunikacijskih pretvarača. Omogućeno je da BMS master uređaj upravlja BMS slave uređajem koji provodi mjerenja napona i temperatura ćelija. BMS master prihvaća mjerne podatke putem SPI (isoSPI) protokola te ih prosljeđuje nakon obrade na računalo putem UART (USB) sučelja. Testiranjem je potvrđeno da razvijeni BMS sustav ispravno radi.

Abstract (english)

In this maser thesis, the principles of operation, configurations and parts of batteries, lithium-ion cells and battery management systems (BMS) were investigated. A custom BMS was designed, consisting of a BMS slave device (for which a printed circuit board was designed in Altium Designer), a BMS master device (an STM32 Nucleo-144 development board was used for this purpose, with custom developed software based on real time operating system FreeRTOS) and communication converters. The BMS master device was programmed to control the BMS slave device that performs voltage and temperature measurements of the battery cells. The BMS master takes the measurement data via the SPI (isoSPI) protocol and forwards processed data to the computer via UART (USB) interface. The tests confirmed that the developed BMS system work correctly.
