Advancing BEV Thermal Management Systems with Model-Based Development

This presentation highlights the advancing BEV thermal management systems and discusses the development and enhancement of thermal management systems (TMS) for Battery Electric Vehicles (BEVs) using MathWorks Model-Based Design (MBD) tools.

It highlights the challenges and goals for development of systems. It demonstrated the fundamentals of the Thermal management systems in BEV including two main subsystems: coolant and Refrigerant system, and how model-based approaches enable efficient simulation, control strategy development, and optimization of thermal systems critical to maintaining battery performance and lifetime.

The presentation demonstrates the system architectures of the system and its components within the MathWorks environment to achieve robust thermal management, improved energy efficiency, and reduced development time for BEV thermal solutions. This approach supports addressing challenges posed by thermal dynamics in electric vehicles through a systematic modeling framework.

It also addresses refrigerant system innovation, focusing on natural refrigerants such as Propane (R290) and Carbon Dioxide (R744), alongside the development of refrigerant systems using emerging fluids like R1234yf. This comprehensive MBD approach, leveraging MathWorks' simulation and system engineering products, accelerates development through code generation and rapid prototyping, optimizes system design, validates the system through test bench and demo vehicle, and improves the reliability of thermal management solutions for BEVs.
