Abstract:	本論文針對傳統電動車的充電冗長問題下提出了改進方案，傳統電動車在電力不足時須耗費相當漫長的時間等待充電，因而限制了使用的方便性與行車範圍。本文提出之電動車交換電池系統，希望能解決傳統電動車充電不便利的問題，首先完成一套可供電池交換的使用者人機介面，使用了RFID 技術的非接觸式智慧卡付款系統，為了隨時監控各模組電池狀態以及控制各閘門馬達和警示燈的主控制板，接下來採用降壓型轉換器硬體架構、同步整流技術和混合型充電方法去完成充電器模組，對於整體系統資料傳輸，將以上硬軟體用RS232 和I2C 傳輸協定技術連結，並整合成一套無人快速自動化交換電池設備，此設備不僅可以一分鐘快速交換電池、自我檢測故障問題，還可以通過人機介面的無線網路功能來傳輸設備錯誤訊息給控制中心的控制人員，讓控制人員得知錯誤訊息後能夠快速維修，讓電動車的使用者可以更可靠的使用，並且克服傳統電動車充電冗長的問題。 This thesis provides an improvement to solve the charging problem on conventional electric vehicles. Traditionally, users have to wait for a long time to charge the battery when it is in low capacity which restricts its convenience and range to drive. Here the new battery exchange system was presented to solve the problem. First of all, we utilized a RFID contactless smart card and a human-machine interface to build a controlling unit. Modulated chargers with synchronous rectifiable buck converters are used to charge the batters on constant current (C.C.) and constant voltage (C.V.) mode. A motherboard which was linked to computer and chargers was used to monitor chargers and control the whole exchanging procedures. The automatic battery exchange system can be operated without porter by automatic error examine and wireless report. The users can use this exchanger to change their used battery within one minute which can totally solve energy problems in electric vehicles.
