摘要:
基于某款电动汽车相关参数,搭建了电动汽车仿真研究模型。结合 NEDC 工况(New European Driving Cycle),开展了动力性和续航里程仿真,发现该电动汽车的驱动系统动力性较好。但在 NEDC 工况中驱动系统集中工作在转速 0 r/min~9000 r/min 和扭矩 0 Nm~110 Nm 范围,且该范围内驱动系统效率较差,导致续航里程较短。为此提出基于 NEDC 工况的驱动系统特征工况点识别方法,结合特征工况点开展驱动系统控制及标定优化,提升了驱动系统效率,提高了续航里程。结果表明,基于特征工况点的驱动系统优化方法是一种提高电动汽车续航里程的有效方法。
Abstract:
Based on the relevant parameters of an electric vehicle, the simulation model of electric vehicle is established. Combinedwith NEDC (new European driving cycle), the simulation of power performance and endurance mileage is carried out, and it is foundthat the driving system of the electric vehicle has better power performance. However, the driving system works in the range of 0-9000r /min speed and 0-110 nm torque in NEDC, and the driving system efficiency is poor in this range, resulting in a short endurance mileage.Therefore, a method of identifying the characteristic operating points of the driving system based on the NEDC operating conditions isproposed. The control and calibration optimization of the driving system is carried out in combination with the characteristic operatingpoints, which improves the efficiency of the driving system and the endurance mileage. The study result shows that the method ofoptimizing driving system based on characteristic operating point is an effective method to improve the endurance mileage of the electricvehicle.
