摘　　要：为了准确分析纯电动汽车的能耗问题,以研究纯电动汽车能量传递为目的,对纯电动汽车系统结构进行了分析。应用多物理标准化统一建模语言Modelica,采用Dymola支撑平台,建立了ECUV纯电动汽车层次化、机电控的统一模型。基于测试数据,对电机及控制系统模型进行了标定、验证。完成了整车工况仿真,针对纯电动汽车整车及子系统的能量消耗,计算得出ECUV纯电动汽车行驶能耗平衡图,提出提高纯电动汽车能量利用率的措施。To analyze the consumption of the electric vehicle（EV） precisely,taking into account of the energy flow,the structure of the EV system is analyzed.Based on the analysis,the hierarchical model of ECUV is established with Modelica using Dymola.The electric drive system is validated and calibrated based on the test data,which is obtained from the test bench.different drive cycle is tested using this EV model,the energy balance under new European driving cycle（NEDC） is calculated by the simulation and the measures to reduce the energy consumption are proposed accordingly.
