摘要
采用AMEsim软件建立了电动汽车能耗特性研究仿真平台。基于此平台研究了集中式驱动电动汽车和分布式驱动电动汽车的驱制动控制策略,重点研究了能耗最优的驱制动控制策略。为表征电动汽车的能量利用特性,定义了平均能效因数等能耗评价指标。在NEDC循环工况下对不同的电机配置形式和采用不同驱制动策略的电动汽车方案进行仿真研究。结果表明,采用能耗最优驱制动策略的分布式驱动方案能耗水平最低,较目前电动汽车的主流方案能耗降低约6%。
The software,AMEsim,is used to develop the simulation platform built for research on characteristics of energy consumption of electric vehicles.Based on the platform,the driving and braking control strategies of centralized and distributed driven electric vehicles are studied,especially the control strategies optimizing the energy consumption.To indicate the features of energy utilization of electric vehicles,the energy consumption evaluation index,such as average energy efficiency factor,is defined.Eventually, many electric vehicle solutions with different motor configurations and control strategies are evaluated through simulation under NEDC cycle.The results show that the best solution is the distributed driven electric vehicle with control strategies optimizing the energy consumption.Its energy consumption is less than current mainstream solution by about 6%.
