LI-PO CELL VOLTAGE EQUALIZER FOR ELECTRIC VEHICLE

Abstract

V diplomskem delu je predstavljeno izravnavanje napolnjenosti Li-Po akumulatorjev. Podani so razlogi za izravnavanje, opisane so možne metode izravnavanja napolnjenosti ter predstavljeni nekateri programski algoritmi, s katerimi lahko mikrokrmilnik nadzoruje in upravlja izravnavanje. Predstavljen je tudi zgrajeni modul, ki izravnava napetosti Li-Po akumulatorjev v električnem vozilu. Modul je namenski in se prilega ohišju akumulatorjev, njegovo srce pa je integrirano vezje LTC6802-1, ki opravlja meritve napetosti posameznih celic. Podani so rezultati meritev ter ugotovitve, do katerih smo prišli med gradnjo in testiranjem.In this diploma the charge equalizing of Li-Po battery is represented. The reasons for equalizing are given and possible methods for charge equalizing are described, further there are given some program algorithms for microcontroller which can control and manage the equalization. We also described the module which equalizes the voltages of Li-Po batteries in an electric vehicle. Module is purpose-built and is designed to fit the housing of the battery. Its “heart” is integrated circuit LTC6802-1 which performs the voltage measurements of each cell. We also present measurements and findings which we reached while constructing and testing
