Comparison of Energetic Macroscopic Representation and Structural Representation on EV Simulation under Simcenter Amesim

Abstract

The development of electric vehicles has been spectacular over the last 20 years, so the automotive industry has started to shift mass production of electrified vehicles. However, new electrified vehicles are required to face the needs of the users. Simulation is a key step for development of new vehicle. Organization tools, such as Energetic Macroscopic Representation (EMR), have therefore been developed to improve and speed-up the development of virtual electric vehicle models. The paper presents a comparison between functional and a structural representation on EV simulation under Simcenter Amesim. This paper studies the impact of the two representations on the simulation results and time. For this purpose, an EMR library for the Simcenter Amesim simulation tool has been developed.

Full Power Constraints HiL Setup for Battery Module Testing in Electric Vehicles

“…It is based on power transfers, physical causality and pictograms representing functions (see Annex A). Equations (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12) give the equations inside the Fig. 4 pictograms.…”

“…The EV model has been validated in [10] with experimental variables recorded in a real Renault Zoe. This model is available on the Simcenter Amesim cloud [11]. This cloud is an online simulation service including libraries of system (EVs for instance) and subsystem models.…”

“…Current peak=126 A In this paper a new battery pack with high power and energy densities has been tested for the Renault Zoe. A Zoe model validated in previous publications has been used [11]. It is organized in EMR.…”

Multi-level simulation of a BEV using EMR methodology

“…An EMR library has been developed within the Simcenter Amesim software [8]. Each EMR or control element is an empty subsystem containing only the input and output ports.…”

“…The "plug & play" ability is possible because this project uses a unified formalism called energetic macroscopic representation (EMR) that clearly defines the inputs and the outputs of subsystems. An EMR-based library has been developed in Simcenter Amesim [8] in that perspective.…”
