Abstract

The development of battery electric vehicles (BEVs) raises a demand to develop a tool to estimate and predict their energy consumption accurately and efficiently. This study proposes a model to estimate the energy consumption of BEVs based on the trajectories of in-use vehicles, including both BEVs and internal combustion engine vehicles (ICEVs). This model consists of three modules: vehicle specific power (VSP) distributions, energy consumption rates, travel time and mileages. The estimation results are validated and compared with those derived from driving cycles and instantaneous speeds. It is found that the VSP distributions can capture the variation of the energy consumption relating to average speeds, and the results are unbiased with average errors less than 1.9%, comparing with instantaneous speeds. It is practicable to employ the trajectories of ICEVs to model the activity of BEVs for energy consumption estimates, and the average errors are less than 2.7%.

基于在用车辆轨迹的电池电动汽车能耗建模

电池电动汽车（BEV）的发展要求开发一种工具来准确有效地估算和预测其能耗。本研究提出了一种基于在用车辆轨迹（包括 BEV 和内燃机车辆（ICEV））的 BEV 能源消耗估算模型。该模型由三个模块组成：车辆比功率（VSP）分布、能耗率、行驶时间和里程。估算结果经过验证，并与驾驶周期和瞬时速度得出的结果进行了比较。结果发现，VSP 分布可以捕捉到与平均速度相关的能源消耗变化，而且结果无偏，与瞬时速度相比，平均误差小于 1.9%。利用内燃机车的轨迹来模拟 BEV 的活动以估计能耗是可行的，平均误差小于 2.7%。

期刊介绍： Transportation Research Part D: Transport and Environment focuses on original research exploring the environmental impacts of transportation, policy responses to these impacts, and their implications for transportation system design, planning, and management. The journal comprehensively covers the interaction between transportation and the environment, ranging from local effects on specific geographical areas to global implications such as natural resource depletion and atmospheric pollution. We welcome research papers across all transportation modes, including maritime, air, and land transportation, assessing their environmental impacts broadly. Papers addressing both mobile aspects and transportation infrastructure are considered. The journal prioritizes empirical findings and policy responses of regulatory, planning, technical, or fiscal nature. Articles are policy-driven, accessible, and applicable to readers from diverse disciplines, emphasizing relevance and practicality. We encourage interdisciplinary submissions and welcome contributions from economically developing and advanced countries alike, reflecting our international orientation.
