摘要: 纯电动汽车电源的利用率与动力传递系统的特性直接影响经济性和动力性。本文采用Advisor软件建立纯电动汽车复合电源模型,包括电池、超级电容、DC-DC、控制策略、速比控制等,通过对非稳定工况下的仿真计算,获得复合电源电动汽车的动力特性;通过对5级变速器的仿真计算,获得动力传动特性及优化方案。本文研究可以为纯电动汽车的研究设计提供一定的理论依据。
Abstract: The characteristics of power supply and power transmission system of pure electric vehicle directly influence on the economy and power performance. In this paper, the Advisor software is used to build the hybrid power supply model of pure electric vehicle, including battery, super capacitor, DC-DC model, control strategy, speed ratio control and so on. Through the simulation calculation of unsteady conditions, the dynamic characteristics of hybrid electric vehicle are obtained; through the simulation calculation of five-stage transmission, the power transmission characteristics and optimization scheme are obtained. The result of this paper can provide a theoretical basis for the research and design of pure electric vehicles.
