  • 摘要
    電動車發展受到續航力影響,在電池材料與製程尚未有重大突破前,如何有效的評估電池效能為目前重要課題;台灣政府也不遺餘力於電動車推廣,並希望在10年內將1萬輛柴油巴士汰換轉為電動化;台灣已有部分都會區推行電動大客車運行,且進行資料蒐集與評估;大客車具備了定時、定點、定距和定人的特性,由於這些特性,在電動車運行資料處理與研究條件設定上,較小客車容易純化設定條件,車輛中心運用電動大客車運行資料並利用上述特性,透過車速、停等次數和溫度等,評估這些參數與電池耗能之關係,藉此估算電動車耗能;另外透過車輛運行數據,嘗試找出判斷電池老化趨勢之方法,藉由此研究對未來的電動車發展與續航評估產生莫大助益。

    Abstract

    The driving range is an important issue of electric car manufacturers and electric vehicle fleet operators,
    and it directly influences the cost, operation and customer satisfaction. The estimation of Battery
    performance which has a significant impact on the driving range is an immature technique, however ARTC
    (Automotive Research & Testing Center) proposed to estimate parameters including energy consumption
    and battery aging. ARTC estimates the driving range by referring the following parameters like the speed,
    the times of start and stop, and the temperature. Battery capacity is another impact factor, and it will
    diminish when battery aging and degradation. However, the decreasing capacity has the enormous
    implications of the range. ARTC presents the down trend of the battery capacity by the EV’s driving data
    statistics, and then the capacity will be predicted from the trend. The bus is characterized by specific time,
    position, path and driver, and it’s suitable to electrification of bus systems. This paper is focused on
    estimating the energy consumption of electric bus. The driving range can be estimated by the speed, the
    times of start and stop, the temperature, and battery capacity, and it will be more accurate. Furthermore,
    this paper will present the trend of the battery aging by the charging capacity of battery. The research will
    help to improve the vehicle’s design, and then support the expansion of electric vehicles.
