摘 要:为了评估技术水平,确定新设计车型关键技术参数以及制定相关政策,统计了中国政府 2014—2016 年发布的 9 批 275 个纯电动乘用车车型的主要性能指标,分析了这些指标的平均、最大 和最小值,以及不同整备质量 m 的车型数量分布。参数范围是: 100 km 能耗为 7.60~34.84 kWh,蓄 电池组比能量为 50.5~199.4 Wh/kg,蓄电池组总质量占车辆整备质量的占比 λ 为 9.95%~31.65%,质 λ 的均值高达 21.43%,远高于传统汽车发动机占整备 量里程能耗为 78.05~225.90 Wh/(km·t)。其中 , 质量的占比; 整备质量 m 小于 1 t 的纯电动乘用车能耗高于政府要求;用 100 km 能耗和质量里程能耗 来评价不同 m 的纯电动乘用车,所得到的结论可能相反。因此,在制定纯电动乘用车能耗限值时,采 用基于整备质量的分段限法。 纯电动乘用车;新能源车 (NEV) ;免税;能耗限值; 蓄电池组比能量; 质量里程能耗 关键词: U 469.72 文献标识码: A DOI: 10.3969/j.issn.1674-8484.2017.02.011 中图分类号:

Abstract: This paper analyzed the key parameters for passenger battery electric vehicles (BEVs) to evaluate the technical level for different vehicle types, to determine the key technical parameters for new design vehicle type, and to make related policies. The data came from the 275 kinds of vehicle model from 9 batches of the catalogue of new energy vehicles (NEVs) from 2014 to 2016 with purchase-tax-exemption released by government. Analyzed the average, the maximum and the minimal value, as well as the quantity distribution with different curb mass (m) for passenger BEVs. As results, the energy consumption per 100 km is ranged at 7.60~34.84 kWh, the energy density of traction battery is 50.53~199.4 Wh/kg, the ratio (λ) is 9.95%~31.65% between traction battery gross mass and vehicle curb mass, and the consumption per mass-mileage-energy is 78.05~225.90 Wh·(km·t)-1; the ratio λ with an average value of 21.43% is much higher than the ratio between

engine-mass and curb-mass for traditional-vehicles; the energy economy performances for BEVs within the mass segments of m ≤ 1 t are much higher than the value desired by Chinese government; it might make an opposite conclusion when evaluating BEVs energy consumption by using energy consumption per 100 km and by using mass-mileage-energy consumption. Therefore, it is recommend to adopt mass-based grouping limit or fitted straight-line method when regulate BEVs energy consumption.
