摘要

為提升續航力雙電力電動機車系統平台之續航力，由原本54V/24Ah锂電池(主動力源)再搭配一100W質子交換膜式的氫氧燃料電池(輔助動力源)驅動1.5kW輪轂馬達。本研究提出兩種限制锂電池輸出功率的方法作為能量管理策略，分別是車速與系統加速性限制，並以ECE40之行車型態，觀察功率限制前後的增程效果。
透過實驗，可歸納出車速限制法可增加6km的行駛里程，其車速在SOC (State of Charge)60%以上最高車速為50km/h而SOC 40-60%時最高車速為40km/h，SOC40%以下時最高車速30km/h，锂錳電池的輸出功率從2188W下降至1270W下降幅度約42%，而模糊邏輯決策的加速性限制功率法可增加0.925km的行駛里程，在SOC60-100%、SOC40-60%、SOC20-40%、SOC0-20%有不同的加速性其消耗能量分別是5.9kWh、5.59kWh、5.14kWh、4.55kWh，比較兩種限制法可發現，車速限制法有16.91%的增程效果，加速性限制法則只有2.9%，就增程性而言車速限制法雖占上風但其最高車速會受到限制，加速性限制法的最高車速不會受到限制其性能優於車速限制法。

To improve the driving range, the study presents a dual power system consisted of 54V/24Ah Li-MnO2 battery and 100W hydrogen fuel cell which is additional installed for range extender. We present two power management strategies that limit speed and acceleration capability. Finally we use ECE40 cycle to validate these two way can upgrade the range of the system. Speed lamination way could add 6 km .The maximum of speed are 50km/h、40km/h、30km/h when SOC (State of Charge) are 60-100%、40-60% and 0-40%，the power of depletion from 2188W to 1270W decline margin is 42%. Acceleration capability lamination could add 0.925 km. When SOC are 60-100%、40-60% 、20-40%、0-20% the energy are 5.9kWh、5.59kWh、5.14kWh、4.55kWh. Compare these two ways speed lamination has 16.91% and acceleration capability lamination has 2.9% range extender effect.
