本論文應用專利分析探討我國電動汽車特有技術之技術發展現況,並分析其技術趨勢。本研究利用M-Trends進行我國自1992年至2012年間專利檢索,經判讀後共得421筆相關專利,繪製相關專利管理圖與技術功效矩陣圖。分析後發現,我國電動汽車特有技術專利於2009年開始成長,且以「控制系統」技術為主。 技術功效矩陣顯示臺灣電動汽車特有技術之主要技術集中於「控制系統」,主要功效集中於「提升」。技術成長曲線則顯示目前電動車產業的特有技術處於技術生命週期的「成長」階段,此階段代表產業技術有突破性發展或此產業開始被重視,並開始投入研發導致專利數量急速成長。 技術功效矩陣圖中觀察發現大部分技術集中於控制系統的充電裝置技術,回顧此技術發展已投入非常多的研發資源,本研究建議此技術擁有足夠基礎,故持續進行相關研發作為未來策略型佈局。此外本研究亦發現充電裝置、能量儲存裝置、馬達繞組之零部件與電池開發設計技術的發明人及專利數量均多,故建議產業應利用此種既有的專業技術人力及過去的研發成果,持續進行技術研發,申請專利作為地雷式佈局。
This thesis uses patent analysis to investigate the technology evelopment of battery electric vehicles (BEV) in Taiwan. 421 patents, granted between 1992 and 2012, are collected. Various patent maps are constructed to investigate the inside of those patents. It is found that the number of granted patents began to soar in 2009, especially in the control system technology. The technology-function matrix indicates that the major technologies focus on the "control systems" of BEV with a dominant function of "to increase". Further analysis finds that, according to the technology life cycle curve (the S curve), the current technology development is on the growth period. The author also suggests that the BEV industry adopt the following strategies: 1. concentrating and continuing the development of control systems, especially in battery recharge, to form a strategic technology of the industry. 2. Based upon the large number of inventors and granted patents in battery recharge, energy storage, motor wiring, it is suggested that the BEV industry further enlarge the scope of technology development to form a blanketing & flooding patents strategy.
