Design of a complete battery management system for application in electric vehicles

U ovom radu proučena je relevantna literatura vezana za sustave upravljanja baterijskog paketa te literatura vezana za nastanak opasnih stanja litij-ionskih ćelija, na temelju kojih je objašnjena je uloga sustava za nadzor baterija. Nadređeni i podređeni uređaji projektirani su u skladu sa novim zahtjevima, pri čemu su dimenzionirani izvori napajanja, objašnjen je uzrok nastanka elektromagnetskih smetnji i metode njihovog smanjenja te je proveden postupak smanjenja elektromagnetskih smetnji podređenog uređaja. Nadalje, objašnjen je način rada 1-Wire senzora temperature te je projektiran krug za mjerenje temperature putem tih senzora. Proučen je i ISO 26262 standard funkcionalne sigurnosti na temelju kojeg je provedena FMEDA metrika jednog hardverskog dijela nadređenog uređaja. Izrađena je i dokumentirana električna shema nadređenog i podređenog uređaja kao i prijedlog nacrta tiskane pločice podređenog uređaja.Within this thesis the relevant literature related to battery pack management systems and the literature related to the occurrence of hazardous states of lithium-ion cells were studied, on the basis of which the role of battery monitoring systems was explained. Master and slave devices are designed in accordance with the new requirements, whereby the power sources were dimensioned, the cause of electromagnetic interference and methods of their reduction were explained, and the procedure of reducing electromagnetic interference of the slave device was performed. Furthermore, the working principle of 1-Wire temperature sensor was explained and temperature measuring circuit was designed. ISO 26262 functional safety standard was studied on the basis of which the FMEDA metrics of one master hardware circuit was performed. Electric scheme of master and slave unit was ddesigned and documented, as well as the printed circuit borad of the slave device
