由於電動巴士及大客車的電池系統昂貴且對電池效能與壽命的要求高，市面上使用的純電動大客車比例仍低，且仍有許多影響電池性能之關鍵技術仍待解決，因此電池系統之驗證與評估對大型電動巴士的設計與開發非常重要。而此類對電池之充放電性能評估更必須搭配實際車輛運行之需求而進行方有價值。為節省實車測試之成本，本研究擬以硬體迴路模擬(Hardware-in-the-loop, HIL)的方式使用TruckSim軟體建立大客車的動態模型，並藉由LabVIEW建立車輛驅動所需的電動馬達模型以進行整車模擬，再透過整車模型連接於實體的電池充放電系統來完成整個硬體迴路模擬平台。透過軟體設定，此平台可模擬電動大客車於不同行駛情境中之動態行為，並可測試電池即時的充、放電所產生的電池反應，同時與電池機櫃通訊得知電池狀態、電壓、電流、溫度等關鍵電池參數，在模擬過程中，使用者也可透過平台觀看模擬時的即時地圖、街景資訊等。

Due to the cost of electric bus battery system and the request of the battery efficiency and life are high, the proportion of using Battery electric vehicle is still low, moreover, there are still many technique problems that may influence battery efficiency are waiting to be solved so battery system verification and evaluation are important to electric bus design and development. In addition, the evaluation of the charge and discharge performance of the battery must be carried out in conjunction with the actual operation of the vehicle. In order to save the cost of vehicle testing, this plan is to use TruckSim to build an electric bus dynamic model and simulate by Hardware-in-the-loop(HIL) method. And build the motor model to drive the entire vehicle by using LabVIEW, then connect to real battery charging and discharging system through the whole vehicle model to complete the HIL system. Through the software setting, this platform can simulate the dynamic behavior of the electric bus in different driving situations, and can test the battery reaction by real time charge and discharge. Simultaneously, we can communicate with the battery cabinet to know the battery state of charge, voltage, current, temperature and other battery parameters. During the simulation, users can also view real-time maps, street view information.
