碩士 === 國立彰化師範大學 === 電機工程學系 === 94 === This thesis investigates estimation of the state-of-charge in lead-acid batteries and battery energy management for battery powered motorcycles. The electrochemical resistance variations in the electrolyte concentrations are estimated for the state-of-charge. This is a real time approach that can be implemented using a digital signal processor. The torque and speed characteristics of a battery powered motorcycle ridden on different road types are used to calculate the energy consumption at various driving ranges. In these experiments, the lead-acid batteries were charged and discharged using different procedures to obtain the variations in the charge and resistance profiles to analyze the accuracy of the proposed methods for estimation the capacitances and residue energies. A test platform was designed using a dynamometer to test the motorcycle. The dynamometer parameters, energy index and driving mileages were tested to evaluate the energy management reliability. The experimental results showed that the methods used to estimate the state-of-charge and manage the energy consumption could optimize the driving mileage in one battery charge for a battery powered motorcycle.
