| Summary: | 碩士 === 國立彰化師範大學 === 工業教育學系 === 87 === The purpose of this thesis is to study the charging and discharging characteristics of the battery usded in an electric vehicle. The electric vehicles are not yet widely accepted for replacement with conventional internal combustion engine cars, due to some unsolved technical problems. The main problem is long battery charging time. In the thesis, different charging techniques were analyzed to find out the charging techniques with shortest charging time and the highest charging efficiency. Another difficult problem associated with the development of electric vehicles is battery residual capacity prediction. A new approach to develop a battery state of charge indictor used in an electric vehicle is discribed and studied. This approach determines the state of charge by combining the open voltage and coulombmetric measurement technique. After elongated testing, the optimum prediction parameters were obtained and summarized.
