今天，运输部门是污染物和温室气体排放的主要来源。燃料电池混合动力汽车是减少其对环境影响的解决方案，这要归功于与全电动汽车相比，燃料电池混合动力汽车的尾气零排放和更长的行驶里程。在这项研究中，通过评估车辆内的机械和热系统模型，开发了一辆FCHEV的数字双胞胎。本文提出的Simulink/Simscape模型能够同时支持设计选择和控制策略的测试。得到的结果可以表征辅助系统对行驶范围的影响，根据环境温度的不同，其相对值在总能源需求的28%到40%之间，对于温和和寒冷的温度，其范围分别在430公里到356公里之间。
The transport sector is today a major source of pollutant and greenhouse gas emissions. Fuel Cell Hybrid Electric Vehicles are a solution to reduce its environmental impact, thanks to the zero pollutant tailpipe emissions and longer driving ranges if compared with full electric vehicles. A Digital Twin of a FCHEV is developed in this study, through the assessment of models of mechanical and thermal systems within the vehicle. The Simulink/Simscape model here presented is able to support both the design choices and the test of control strategies. The results obtained allow characterizing the impact of the auxiliary systems on the driving range, whose relative value ranges from 28% to 40% of the overall energy demand depending on the ambient temperature, and the range is between 430 km and 356 km respectively for mild and cold temperature.
