| Summary: | 碩士 === 國立臺北科技大學 === 車輛工程系所 === 101 === Observation of the current marketed electric scooter the biggest problem is lack of cruising range, and charging facilities are not enough, for the use of the lack of practicality. Therefore, this research is to enhance electric scooter cruising range and improve battery charging inconvenient problem, we used hydrogen fuel cell in electric scooter become a dual power system, the lithium battery as primary power and low power-type hydrogen fuel cell as auxiliary power, through the designed power and signal integration system, and monitoring system, to achieve the Dual Power System for Extension (DPES) and enhance the purpose of cruising range.
In this study, we use the experimental platform and ECE-40 driving cycle to compare respectively single power and dual power, and the data acquisition system can record the system voltage, current, power and SOC data to validate effects of low power-type fuel cell as auxiliary power source for range extended. We found that dual power strategy - a fuel cell auxiliary power output of 100W at full-time full load and when idle to recharge the battery, and compared to single power case, the battery discharge slope and SOC slope tends gentle, driving distance from the original 29.8km increase to 37.9km, added about 8 km distance, and the extended-range rate reached 21%. In addition, it has a low cost, the systems structure simple and space configuration easy.
