摘要

由於現今的純電動車續航力皆不高，而充電站也不多。為了避免電動車的駕駛在行駛期間遇到電瓶沒電但又找不到充電站之情況，本研究設計一套渦輪發電系統，提供電動車在無電量之情況下進行緊急充電的功能，讓電動車能靠此系統行駛至充電站。
本研究承襲之前的研究經驗，以一顆體型較小的渦輪引擎作為動力源。依引擎之特性規劃一套系統支架，並將小型之馬達當作發電機用以輸出電力。根據前期的開發經驗，發電機在運轉時會有過熱與對心準確度之問題。因此本研究針對發電機設計一套散熱裝置幫助其散熱，並依據發電機與引擎之特性選擇合適之連接裝置，再以校正工具進行對心校正。
本研究對於渦輪引擎發動時所產生之龐大噪音量，研究各種消音方法進行改善。 除了採用消音材料進行包覆工作外，還使用消音器進行實驗，測試其可行性。在實驗方面，本研究對系統作發電量之測試，測試系統的各項性能。而噪音測試的部分，本研究找尋合適之法規進行系統的各項噪音量測，測試系統消音之成效。

Because of low battery endurance of the current electric vehicles and there are not many charging stations, we try to improve the situation when batteries run out and the driver needs backup power during driving. A microturbine generator system is designed in this research, supplying power to charge the batteries of BEVs under this situation. As a result, BEVs are able to have better cruising range.
Previous research experiences are continued, using a smaller turbo engine as the power source. Frame systems are designed based on the characteristics of the engine, and a small motor is used as a generator to generate electricity. According to early development experiences, the generator has some problems including overheating and misalignment of the shafts. Therefore, a device is designed to help cooling the generator, and appropriate connection devices are chosen based on the characteristics of the engine and the generator. Rectification tools are then used to rectify the misalignment of the shafts.
Some methods were found to reduce the noise when the turbine engine was in operation. In addition to using the noise elimination materials to package the system, a muffler is also used to test whether it can further reduce the noise. As for the experiment, we tested the performance of the microturbine generator system. In noise test, suitable standards are found to measure different noise data of the system to test the effects of the noise reduction.
