Optimizing Electric Powertrain Performance Through System-Level Modeling

With electrification taking center stage in the mobility segment, the need for reliable high-performance electric powertrains with shorter development times has become even greater. Model-Based Design is a preferred approach to improving product quality and achieving a faster time to market.

In this presentation, we discuss how a system-level model helps us understand component-level requirements and interactions between the components. The team utilized insights to create component-level models using Simulink^® and Simscape™. These models were then combined to analyze system-level details and optimize performance, range, and cost.

The presentation covers the following points:

• Understanding system architecture to comprehend interactions between components and their specifications/sizes, including trade-off studies.
• Using Simulink and Simscape to model individual components such as motors and batteries.
• Integrating the component models and combining them with environmental and driver models to optimize system performance and range by changing the gear ratio.
• Testing and validating system performance.
