Context:
The Control team at L2EP conducts research on modeling and control formalisms for electromechanical systems, similar to the Macroscopic Energy Representation (EMR, emr-website.univ-lille.fr/). Within this framework, stakeholders in the "Electricity & Vehicles" theme (eV) are developing new control laws and energy management strategies for vehicles utilizing the electric vector (electric vehicles, hybrid vehicles, etc.). The eV platform is shared across two locations. The first site is located on the campus of the University of Lille, and the second site is at the National School of Arts and Crafts of Lille (ENSAM).
Platform objective:
After simulating and developing the control for new concepts of electric or hybrid vehicles, precise and progressive validations are necessary before implementing them on a real prototype. The "eV" platform aims to experimentally validate these new concepts before implementation on a real vehicle. The platform is one of the three open experimental platforms in the MEGEVH network and has contributed to the experimental validation of numerous MEGEVH projects (Dr. Tony Letrouvé's thesis - Emulation of the Peugeot 3008).
Flexibility:
To test different vehicles (with various architectures) and subsystems designed for the vehicle, the eV platform is based on basic software components (MER library, control programs, supervision programs) and hardware components (electric machines, power electronics, energy storage systems, mechanical transmission, electric vehicles, control electronic cards), which can be arranged according to chosen objectives and applications.
Power Hardware-in-the-Loop Simulation :
The real-time emulation principle (or Hardware-In-the-Loop simulation) is at the core of the platform. It allows the study of various controls and new subsystems by simulating their interactions with other subsystems.
After creating and validating a simulation program for the studied vehicle, its control is extracted to control, in real-time, a physical system that emulates the same vehicle. Finally, the vehicle's behavior and performance can be observed before its actual creation. Naturally, the choice of the precision level of the Vehicle model must be made based on the validation objectives of the subsystems.
