Simulation of Electric Vehicle Battery System

The battery system serves as the most crucial and costly component powering electric vehicles (EVs). Effective design of such systems heavily relies on computational simulation tools rather than physical test platforms. This paper outlines a process for simulating Battery Electric Vehicle (BEV) battery systems utilizing Siemens Simcenter software. This procedure encompasses the modeling and simulation of battery cells, packs, and systems through the use of Reduced Order Models (ROMs), EV battery management systems, and Digital Twins. Implementation of this process enhances the battery system’s efficiency, performance, stability, and safety on a BEV, allowing a comprehensive evaluation of the system. By connecting a fully developed battery system to a vehicle dynamics model, the performance of the vehicle can be assessed under specific operational conditions. This methodology empowers designers to achieve optimal outcomes and seamlessly incorporate the battery system into the BEV’s overall design.
