Abstract

This work is devoted to the efficient simulation of large multi-physical networks stemming from automated modelling processes in system simulation software. The simulation of hybrid, battery and fuel cell electric vehicle applications requires the coupling of electrical, mechanical, fluid, and thermal networks. Each network is established by combining the connection structure of a graph with physical equations of elementary components and resulting in a DAE (differential algebraic equation). To speed up the simulation a non-iterative multirate time integration co-simulation method for the system of coupled DAEs is established. The power of the multirate method is shown via two representative examples of battery powered electric vehicle with a cooling system for the battery pack and a three phase inverter with a cooling system. This work is an extended version of (Kolmbauer et al. in Scientific Computing in Electrical Engineering (SCEE 2020), Springer, Cham, pp. 231–240, 2021).

多速率dae仿真及其在电动汽车开发系统仿真软件中的应用

这项工作致力于大型多物理网络的高效仿真，源于系统仿真软件中的自动化建模过程。混合动力、电池和燃料电池电动汽车应用的仿真需要电、机械、流体和热网络的耦合。将图的连接结构与初等分量的物理方程相结合，得到一个微分代数方程(DAE)，从而建立每个网络。为了加快仿真速度，建立了耦合DAEs系统的非迭代多速率时间积分联合仿真方法。通过具有用于电池组的冷却系统的电池供电的电动汽车和具有冷却系统的三相逆变器的两个代表性示例显示了多倍率方法的功率。这项工作是(Kolmbauer et al. in Scientific Computing in Electrical Engineering (SCEE 2020)， Springer, Cham, pp. 231 - 240,2021)的扩展版本。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
