Poster prsented at the 13th IEEE International Conference and Exposition on Electrical and Power Engineering (EPEi 2024). 17-19 October 2024, Iaşi, Romania. 

This poster outlines a design methodology for axial flux permanent magnet synchronous machines (AFPMs) aimed at electric vehicle applications. A simplified analytical model for electromagnetic design is proposed, also the design choices related to machine topology: stator, and rotor structures. Three rotor configurations: SPM, flux-concentrating IPM, and V-shaped IPM are compared based on peak and continuous performance, magnetic attraction forces, and demagnetization risk. The findings provide insights into optimizing AFPM design for electric drivetrains.

This article explores the optimal or near-optimal design configuration of a three-level neutral-point-clamped traction inverter for electric vehicles based on switching-cell array devices. From the definition of a suitable design optimization problem taking into account efficiency, reliability, and simplicity, the optimal solution for the leg configuration and operation is obtained under different scenarios and operating conditions. It is concluded that, in each case, the main operating conditions may decisively influence the selected design.

The report outlines the design, manufacturing, and validation process for the VOLTCAR electric traction motor. It details the motor's specifications, including a high specific power of 7 kW/kg and a power density of over 23 kW/l, with a rated power of 120 kW. The motor is designed for passenger cars and light commercial vehicles, aiming to minimize or eliminate the use of rare earth materials.

This study presents a smart EV charging infrastructure framework composed of a green power generation network, an energy storage network, and a charging network. The digital twin, as an enabling technology, is applied to realise essential smart features for the EV charging infrastructure, including cognisant, adaptive, taskable, and ethical. Based on the proposed smart charging station framework, we systematically review the existing digital twin implementations in the smart charging infrastructure.

The report describes the methodology of the Ecodesign process with a focus on environmental-, criticality- and circularity considerations concerning the RHODaS integrated motor drive (IMD). A Life cycle assessment (LCA) screening according to the ISO 14040/44 standard is performed for the environmental consideration. Within the project 30 % of the total IMD's Global Warming Potential (GWP) should be reduced. The methodology for circularity and criticality is roughly presented and still under development. Reference products and intended improved solutions, needed for later assessments, are described as far as possible. Furthermore, conceptual material/product selection matrixes, as part of the Ecodesign Guideline are presented.

Multi-Moby project, funded under H2020 n° 101006953, aims at developing technology for safe, efficient and affordable urban electric vehicles. The objective of the paper is to show the results achieved in relation to structural integrity and occupant protection in the first year of the project. In a first stage simulation tools have been used to optimise the vehicle structure crashworthiness at different crash configuration based on smart use of High Strength Steels focused to simplified and affordable manufacturing processes. Once the structural behaviour met requirements and expectations, the restraint system has been developed. After design optimisation, three vehicles have been prototyped to perform three crash tests, two of them frontal, corresponding to Regulation 137 and Regulation 94, and one lateral, corresponding to Regulation 95.

In this paper a new design model of the electric vehicle is presented. This model is based on the combination of Modelica with ModelCenter. Modelica has been used to model and simulate the electric vehicle and ModelCenter has been used to optimize the design variables. The model ensures that the requirements related to driving distance and acceleration are fulfilled.

During the last 15 years, the automotive domain has been subject to several disruptive transformations, impacting the full supply chain and enabling the uptake of new services and solutions around road-based passenger mobility and freight transportation. Electrification, CCAM, and SDV are leading to a total redesigning of the vehicle and its components, and very equally to a rethinking of how to deliver value. While software is playing a key role for value creation, it strongly relies on innovative mechatronics platforms and smart powertrain and chassis components as foundation for the SDV of the future. Target of this paper is to introduce the results of the three complementary research projects HighScape, EM-TECH, and SmartCorners, with the focus to deliver consistent innovation along the three following pillars: (a) electrified powertrain and chassis components, (b) vehicle platform and highly integrated corner solutions, and (c) novel control algorithms making use of smart components.
