VEDECOM is attending EVS32, the leading international scientific conference on vehicle electrification

May, the 20th

The VEDECOM Institute will be present at the 32^nd annual Electric Vehicles Symposium (EVS32) which will be held from 19 to 22 May 2019, in Lyon. The Institute will have a stand presenting their work in the field of vehicle electrification and charging, with four Institute researchers taking part. VEDECOM will also conduct two innovative electric charging demonstrations in partnership with the Renault group.

EVS32: Promoting sustainable electric mobility

EVS32 is the leading international conference on the issues of vehicle electrification, connectivity and autonomy. Each year, it gathers the major innovation leaders in the electric vehicle field, and addresses all elements of electric mobility: markets, battery technology, charging systems, public policy and services, etcetera. The programme will include seminars with the leading specialists on the subject, demonstrations, tests of the latest innovations on the market, meetings and more. The aim is to promote sustainable mobility and to allow participants to enhance their knowledge in the field of electric mobility.

A presentation booth for VEDECOM’s activities in the field of vehicle electrification

The VEDECOM Institute will maintain a booth throughout the symposium (booth F19). The displays will in particular include the new induction coils for dynamic charging tracks. Developed entirely in-house, these new 30 KW coils provide the building blocks of a new electrical charging track by induction, allowing the vehicle to offset its energy expenditure, and thus increase its autonomy. A touchscreen will allow visitors to explore the Institute’s electrical motor production plant in 360°: this unique laboratory, installed in the research teams’ immediate vicinity, enables the rapid prototyping of electric motors and fosters the acceleration of innovation. And lastly, screens will present VEDECOM’s work in the area of vehicle electrification. This is organised around two key objectives: expanding the autonomy of electric vehicles, and reducing the size and cost of their motors.

Four researchers present their findings on electric motors and charging

In addition, four VEDECOM researchers will present their findings on the subjects of charging and electric motors.

Sid Ali Randi, an engineer in the design and production of innovative electric motors, will speak on the topic of “Performance analysis of a hybrid excitation flux-switching motor for a PHEV type application”. He will present its operating function, as well as its benefits. The approach used allows for the mapping of the entirety of this new motor’s performance, currently in the process of prototyping.

Emilia Suomalainen, Project Lead at Energie Partagée, will comment on a poster titled “Study of the investment cost for the development of charging infrastructure on a stretch of motorway”. Whilst one of the main obstacles to the mass deployment of electric vehicles is the under-development of infrastructures, she will exhibit a simplified infrastructure model comparing the deployment costs of two electric vehicle charging solutions on stretches of motorway: rapid recharging stations and dynamic vehicle charging channels.

Stéphane Laporte, FABRIC’s Head of Project, will be making a presentation on “The Versailles-Satory charging infrastructure for the testing of contactless dynamic charging”. He’ll present the pilot scheme implemented in Versailles-Satory to develop and evaluate the performance of contactless dynamic charging prototype systems, as well as the experimental studies that aim to characterise such prototypes in real driving conditions.

Jihen Sakly, an engineer in innovative charging systems, will compare h-bridge and cascaded, multilevel topologies for the contactless charging of electric vehicles. She will in particular present the experimental validation carried out on the charging track by the 3kW contactless induction developed by VEDECOM.

Two electrical charging demonstrations in partnership with Renault

Two electrical charging demonstrations will also be presented at Renault’s booth; Renault is VEDECOM’s partner in the two initiatives. A charging station equipped with two plugs and two screens will enable simulation of charging in a public space, as well as home charging. The first demonstration, called “Plug and Charge”, will present the simplification of the systems of identifying and charging vehicles across public stations. At present, connecting and charging are dependent on the reading of a badge by the bollard: it is this badge that allows the vehicle to be recognised and to deliver the required authorisations for the charge. Ultimately, the vehicle will be automatically recognised by the bollard, for a simplification of the steps involved in charging.

The second demonstration will present a simulation of bi-directional home charging. Currently being tested by Renault in the Netherlands, this technology allows electric vehicles to return the energy stored in their batteries to the electric network, and to better regulate the charge. This is thus performed at a maximum when the supply is most abundant, particularly during renewable energy production peaks. Conversely, in peak periods, the vehicle can feed energy back into the network in order to help smooth out the peaks in consumption, and may therefore serve as a temporary energy storage unit. The vehicles are equipped with embedded bi-directional chargers coupled to a software component developed by the VEDECOM Institute in partnership with Trialog, which provides communication between the vehicle and the bollard.
