基于发电能耗折算的电动汽车节能分析

Analysis of Electric Vehicle Energy Conservation Based on Power Generation Energy Consumption

电动汽车作为未来汽车产业的发展方向,其节能与减排效果受到广泛的关注。本文提出一种基于发电能耗折算的电动汽车能耗计算方法,对电动汽车和燃油汽车同等使用条件下的用车成本、消耗的标准煤量及能源利用效率3个方面进行比较研究,推定电动汽车在节能方面的优势。通过比较研究表明,即便在我国煤电占比80%的情况下,电动汽车仍具有明显的节能作用。

The electric vehicle is the future direction of development of automobile industry and its effects of energy saving and emission reduction attract much attention. The paper presents an electric vehicle energy consumption calculation method based on power generation energy consumption. Under the same using condition, the paper carries on comparative research on the cost of using them, the standard coal consumption and energy utilization efficiency in electric vehicle and oil-fueled automotive to presume advantages of electric vehicle in energy conservation. By comparative research, the results show that even in our country coal power accounted for 80%, the electric vehicle still has obvious effect in energy saving.
