Thesis: Vehicle-to-vehicle fast charging from a shared vehicle fleet

Yacine SEHIMI, Researcher PhD Candidate, will submit his thesis on 7 July 2022 at 2 PM on “the design of a vehicle-to-vehicle fast charging network and infrastructure based on a shared vehicle fleet“. Sharing would limit the impact of recharging on the grid at times of high electricity demand. The thesis also presents a tool for simulating power control during the transfer between vehicles.

This thesis will take place at T128 – T130, 13 Rue de Toul 59000 Lille.

Resume

V2V fast charging enables to recharge an electric vehicle by partially discharging one or several other electric vehicles having an excess of energy.  The use of a fleet of carsharing electric vehicles as energy providers allows the carsharing operator to make additional profits when they are not rented.

Moreover, the recharge of the fleet can be achieved at lower power than the V2V power transfer. Therefore the grid connection required to provide fast charging is reduced, which can mitigate the necessary grid upgrades. Besides, the lower power demand of the station could reduce the impact of electric vehicle charging at hours of peak power demand on the grid.

This thesis is a collaboration between Institut Vedecom and L2EP Laboratory. In a first part, the  goal is to build a simulation model of the coupled carsharing/V2V system, in order to assess  the benefits for the actors of the grid, namely the Distribution System Operator and the Transmission System Operator.  In a second part, the design of a power converters architecture to control power flow between the vehicles involved and the grid is proposed and the control strategy is implemented through simulations. Finally an experimental setup of the multi-source DC/DC converter is achieved in order to validate the proposed control strategy.

The results of the French test site of the 5G-MOBIX project in video

Discover in this video the first results of the French team of the European 5G-MOBIX project. This demonstration shows two use cases of 5G for connected and automated mobility.The combination of low latency and very high data rates provides greater reliability and security, even in low visibility or cross-border areas.

Coordinated by VEDECOM, the French trial site of the H2020 5G-MOBIX project tested the contribution of 5G during “infrastructure-assisted advanced driving” and the maintenance of service in cross-border conditions.

Carried out on the Versailles Satory runway, the demonstration presents use cases tested in France and in the Spain-Portugal cross-border corridor: the automated lane change of a level 4 vehicle assisted by the infrastructure when a basic vehicle is inserted; then maintaining connectivity between two networks (TDF and Bouygues).

The French 5G-MOBIX trial site is coordinated by VEDECOM in partnership with AKKA technologies, Valeo, Catapult. TDF contributed its expertise in critical networks and mobile edge computing by equipping the test runaway with a 5G infrastructure.

Regards croisés about autonomous cars

VEDECOM will participate at the Regards Croisés 2022 congress about automated mobiliy. This congress will take place on September 1, 2022  (to be define) from 13H45 to 15H30 at Maison de la RATP, 54 Quai de la Rapée 75012 PARIS.

Stéphanie Coeugnet, R&D Director for New Mobility Solutions and Shared Energy, will speak at 2:40 p.m. during the round table: “Myths and realities of autonomous mobility in rural areas”.

This round table will be an opportunity to discuss the needs of the territories and the uses of automated mobility. What is the acceptability of French people and local elected officials? She will be taling with Cédric Szabo, GEneral Manager of the Association of Rural Mayors of France (AMRF).

5G benefits for automated vehicles: first lessons learned by 5G-MOBIX French trial site

The 5G-MOBIX project aims to evaluate the contribution of 5G on connectivity for Connected and Automated Mobility (CAM) services and functionalities, under cross-border conditions. The 5G-MOBIX test sites include two cross-border corridors (Greece-Turkey and Spain-Portugal) and six local test sites in France, Germany, the Netherlands, Finland, China and South Korea. The local sites provide additional and complementary contributions to the cross-border trials

 

A safe and efficient driving at highway entry for automated vehicles

5G-MOBIX French Trial Site has four members, VEDECOM (leader), Catapult, Akka, and Valeo, and is located in the Paris region. The French Trial Site (FR TS) has been testing a so-called “Infrastructure-Assisted Advanced Driving” CAM use-case, in which the 5G MEC infrastructure guides automated connected vehicle for safe and efficient driving at a highway entry.

 

A level 4 car with a 5G onboard unit 

Several cross-border issues have been tackled by the FR TS with the solutions of multi-PLMN connectivity, predictive quality of service (QoS), Wave connectivity, and satellite-fallback. 5G NSA networks provided by three French telecom operators, Orange, Bouygues and TDF, have been used to test the target use case and the considered solutions.

During the period of the project, the FR TS has deployed two MEC that were installed with a number of software modules, particularly V2X-application server, data fusion, risk assessment, QoS prediction, KPI manager. Six 5G onboard units (OBUs) designed by VEDECOM and VALEO have been integrated in the two level 4 automated vehicle and the two connected vehicles.

 

Test and trialling in both private and open road, including a cross border corridor

Test and trialling activities of the FR TS started in late 2021 in order to execute a huge number of use-case-specific and agnostic tests cases in closed test tracks and open road. Furthermore, the FR TS made two contributions to the ES-PT cross border corridor:

  1. test and benchmarking of multi-PLMN connectivity
  2. contribution to the ES-PT variant of advanced driving use case. The tests at the ES-PT have been conducted in March 2022.

 

Results and public demonstration on April 21, 2022

The obtained results of the test-cases finalised in France and at the ES-PT CBC show the benefits of 5G for the target CAM use-case especially the great advantages of multi-PLMN connectivity.

On the 21st of the April, the FR TS has organized its public demonstration event with public authorities, industries, SMEs, and academia. The event consisted of a workshop session, demonstrations, and an unprecedented round-table discussion.
