Summary: | 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.
