近年由於環保意識高漲，再加上能源危機的逐漸到來,使得電動車輛的發展逐漸受到重視，因此各國科學家紛紛的投入研究發展。有鑑於此，發展電動機車勢必成為台灣未來機車市場上的主流。然而電動機車設計時的性能參數並無法有效任意更改與預測，所以本論文在以此考慮需求之下，使用Sbaer軟體建立一套能有效改變電動機車各部位之參數，以模擬出電動機車之整體性能，以做為研究改良之參考。
在本論文中除了建立一套電動機車整體性能模擬之外，驅動器開關元件的溫升問題通常也是一個研究的重點，因此在驅動器方面則加入了半導體開關元件IGBT的溫升模擬，利用Saber模擬軟體內建的溫升模擬電路元件模型來模擬所使用的IGBT在不同的條件之下IGBT的溫升變化，以期能夠預測出IGBT工作溫度，以作為參考，讓設計者設計出一安全又穩定的驅動器。

Recently, the development of electric vehicles has become gradually attractive due to the growing concerns on the environmental protection and the forecasting shortage of fossil energy. Therefore, numerous scientists around the world have devoted to the research and development in this respect in the past. As a contrast to this development, electric scooters have become the main research effort in Taiwan because the important motorcycle market. In the design process, the parameters of performance cannot be arbitrarily changed nor be correctly predicted due to the lack of proper simulation tools. The objective of this thesis is to employ the S r simulation software for establishing a systematic simulation process to calculate the total performances of the electric scooters under the influences of pertinent parameters.
In addition to the establishment of the systematic simulation process, the temperature rise of the switching devices on the driving circuits was also studied. Hence, the simulation of both the transient and steady temperature of IGBT was performed with given environmental conditions. By making use of the basic mechanistic templates of physical devices given by the Saber, the working temperature of the IGBT under various load conditions was simulated and certainly forecasted for design consideration. As a result, better system design with suitable safety and comfort situation could be satisfied.
