课程介绍

PowertrainLive是一款针对新能源汽车及传统车整车性能仿真分析软件,可以用来评价整车燃油经济性、电池续航能力、CO2排放量等指标。该软件内置多种汽车标定模型,涵盖传统动力、混合动力、插电式混合动力以及电动力汽车等多种类型,可以方便快捷地用来测试某一组件对汽车整体性能的影响。预置的实车标定模型:传统车如Ford Focus、混动车如Toyota Prius、电动车如BMW-i3等。可对不同道路循环测试工况进行整车性能分析,如UDDS冷启动、UDDS热启动百公里油耗。

 

该系列视频介绍了PowertrainLive的一般操作流程,并依次举例说明了PowertrainLive在评价组件特性对汽车性能影响方面的应用,包括自动变速器换挡规律、空调系统、发动机暖机、电池特性等对燃油经济/电池续航力的影响。

新增两课时:

《PowertrainLive - Impact of AC Load on ConvertionandHybrid》基于传统动力车以及插电式混合动力汽车,举例说明空调系统作为机械附件对燃油经济性/电池续航能力的重要影响。此视频中对传统动力车进行高速公路工况测试,总行程10.27英里,空调关闭则油耗0.39加仑,空调打开则油耗0.42加仑;对插电式混合动力汽车进行UDDS工况测试,总行程7.43英里,空调关闭耗电1.4千瓦小时,空调打开则耗电2.16千瓦小时。由此空调系统耗能可见一斑。

 

《PowertrainLive - Modeling Li-ion_Battry》详细阐述了PowertrainLive对电动汽车的仿真过程,参数输入主要包括串/并联电池数目,电池性能数据(包括开路电压、电阻以及电容图等);结果输出主要有电池荷电状态、终端电压、电流输出情况以及电池产热等。而电池产热值可以用来与其他CAE软件进行联合仿真,从而对其进行有效热管理。该视频中以改变电池的内阻特性来说明电池性能数据对电池续航力以及其他性能的影响。

 

PowertrainLive is a high fidelity, predictive, vehicle simulation software as a service that evaluates the vehicle-level impacts of technologies and components on fuel economy and system performance. Examples of what can be simulated through PowertrainLive include: higher efficiency components, waste heat recovery, and new control algorithms. In PowertrainLive, each vehicle subsystem is built on detailed physics and performance maps.
