碩士 === 國立臺南大學 === 電機工程研究所 === 99 === Many of portable devices, such as mobile phone and notebook, have grown explosively in recent years. The electric power demand of these devices almost relies on small energy storage element. Therefore, the rechargeable batteries have been widely used to power these equipments. Under the concepts, this thesis is aimed to develop a real-time battery information platform with the intelligent energy estimation based on the monitoring and computation of programmable ARM-based system, Labview, and dsPIC micro-controller. In this method, the polynomial function is firstly included through the measurement of output voltage with respect to a certain SOC value. Then using the obtained function of battery intrinsic, a method to estimate residual energy of battery is suggested. The method proposed in this thesis is examined under various scenarios. The results help consolidate the feasibility and practicability of the approach for the applications considered.
