纯电动汽车动力电池匹配技术的研究

Research on pure electric vehicle battery technology match

为了保证纯电动汽车在不同路况下均能高效与安全行驶,以磷酸铁锂电池为动力源,利用ADVISOR对某款纯电动汽车的动力电池和整车系统进行了匹配研究。并分别在美国城市驱动工况UDDS和欧洲行驶循环NEDC工况下对匹配度进行了循环仿真分析,在满足汽车动力性的条件下,对多种方案分别进行了参数匹配和优化,最终得到了一套最适合该种电动汽车的匹配方案。

In order to ensure that pure electric vehicles can efficiently and safely drive under different road conditions,lithium iron phosphate was used as the power source,and ADVISOR was used to match pure electric car battery systems and vehicle.The matching degree was simulated circularly under driving conditions in UDDS American cities and European driving cycle NEDC conditions.Under the conditions of meeting the vehicle dynamics,the parameters were matched and optimized by a variety of programs,and finally,a matching program best suited to this kind of electric vehicles was obtained.
