Reduced-Scale Hardware-in-the-Loop Platform for Dual-Source Off-Road Electric Vehicle using Energetic Macroscopic Representation

This paper explores the transition from full-scale simulation to reduced-scale hardware-in-the-loop testing using Energetic Macroscopic Representation (EMR) for dual-source offroad electric vehicles. A comprehensive EMR model is developed, incorporating two energy sources (batteries and super capacitors). Full-scale simulation is established for further vehicle performance optimization. Reduced-scale hardware-in-the-loop testing creates a physical prototype, integrated with the EMR simulation platform for real-time interaction. This approach offers cost-effective validation of EMR-based strategies development, evaluating performance and energy management indicators. It enables iterative design improvements and rapid prototyping. Integration of the reduced-scale prototype with EMR simulation software facilitates seamless data exchange and control signal interaction. Simulations on the prototype verify the accuracy and effectiveness of EMR-based strategies. Results are compared with full-scale simulation, establishing the reliability of the EMS model. This transition enables the development and validation of strategies for our off-road electric vehicle, ensuring accurate performance evaluation and optimization. The research demonstrates the potential of EMR as a valuable tool for advanced electric vehicle system design and development.
