碩士 === 大葉大學 === 車輛工程學系碩士班 === 93 === The purpose of this study is to develop the electrical energy system for parallel hybrid golf vehicle. Because nowadays use in golf vehicle lead-acid battery all act for the hermetically style lead-acid battery, so that can not directly take advantage of lead-acid battery electrolyte specific gravity to estimation the hermetically style lead-acid battery state of charge. Dissertation to understand lead-acid battery characteristic, at first research aim for 12V/26Ah open style lead-acid battery, by means of by research open style lead-acid battery state of charge, let us towards lead-acid battery characteristic have certain acquaintance . Go on exist research object change for 12V/135Ah hermetically style lead-acid battery. Because hermetically style lead-acid battery discharge time of internal resistance with battery state of charge have close correlation, And then this dissertation then battery internal resistance makes research with unfasten to lead-acid, and direct to all sorts of lead-acid battery state of charge estimation means go to make unfasten, final this dissertation takes advantage of improve style internal resistance method estimation hermetically style lead-acid battery state of charge, because should battery material relation, we estimate the internal resistance and divide big and small current two part, overcome hermetically style lead-acid battery nature can not as specific gravity method estimation state of charge. Using LabVIEW to design parallel hybrid golf vehicle electrical energy system, use to PCI-6024E data extract card to extract 12V/135Ah hermetically style lead-acid battery signal, obturate signal by PCI-6024E biography to parallel hybrid golf vehicle electrical -venergy system. Let battery user can know battery's condition clearly, as avoid hermetically style lead-acid battery over discharge, damage to use life. And towards alternator output efficiency relation makes to exciting current, state of charge lack time at battery, can proceed charge to battery.
