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.

E-mobility: a successfull demonstration of the Certificate Trust List for Plug & Charge interoperability

The Certificate Trust List has been demonstrated on the 2nd of June 2021 as a technical solution for ISO 15118 Plug and Charge interoperability.

The objective is to simplify the user experience wherever he is and guarantee the interoperability between any vehicle and any charging station. Such architecture shall enable an open and fair market between all EV actors.

Guarantee the interoperability with multiple actors

2 online identical sessions were broadcast live from Arnhem (Netherlands), Berlin (Germany) and Versailles (France).

The demonstration was operated by 17 actors representing different roles in the Electromobility domain, research institutes,  manufacturers, cybersecurity actors, operators, interoperability platforms, charging infrastructure installers: Driivz, ​e clearing.net, ElaadNL, Freshmile, GIREVE, Hager, Hubject, IoTecha, NewMotion, Groupe Renault, SAP, Smartlab, Stellantis, Thales, Trialog, VEDECOM, Verisco

The demonstration was done in real conditions using different electric vehicles, charging stations and IT services (including PKI) in order to demonstrate the interoperability scenarios.

Promote an open and fair market for eMobility services

Electromobility actors are ready to adopt and deploy new services that will improve the user experience, such as Plug and Charge and Smart Charging. Those services should be interoperable and rely on the ISO 15118 standard. To do this, adopting a single reference architecture, from a technical and organizational point of view, is vital. Such architecture shall enable an open and fair market between all EV actors and allow end-users and operators to freely select their providers.

In this spirit, a collaborative work has started since 2019 to define and test multiple technical solutions. The partners mainly focused on PKI architectures that allow the development of  multiple interoperable offers.

The French initiative Mobena is part of the demonstration

Mobena, a French initiative towards the new generation of electromobility, closely followed this demonstration, in which several of its members intervened.

The Mobena initiative was created in July 2020 by the main French professional organizations representing the electromobility ecosystem in the French market. The goal is to simplify the user experience by ensuring interoperability between charging systems and leading the way towards the deployment of a new generation of EV charging in the French market.

Coordinated by VEDECOM institute, the Mobena initiative regroups AFIREV, AVERE-France, PFA, GIMELEC, UFE and VEDECOM.

About twenty companies representing the different roles in the ecosystem have joined this initiative. The mission is to support the players of the EV charging ecosystem, operating in France, by defining the roadmap and the means to ensure a successful and harmonized deployment of the e-Mobility services.

The Mobena project, which will be launched in september 2021 and extended to more partners, will particularly focus on integrating interoperability as an initial requirement and providing high added value services through a massive adoption of the ISO 15118 standard in a competitive and open market.

A particular focus will be put on Smart Charging, Plug & Charge and the implicated end-to-end system interfaces, including backend communication protocols (OCPP, OCPI…), PKI and cyber security. This for both AC and DC charging.

The Mobena initiative accelerates the roll-out of new generation e-Mobility

Mobena harmonizes the deployment of new services for EV charging

May 17, 2021. The Mobena initiative was created in July 2020 by the main French professional organizations representing the electromobility ecosystem in the French market. The goal is to simplify the user experience by ensuring interoperability between charging systems and leading the way towards the deployment of a new generation of EV charging in the French market. The initiative now reaches two key milestones:

  1. the demonstration of an interoperability solution between multiple PKI (Public Key Infrastructure), organized with international partners of June 2nd, 2021. Learn more
  2. the kick-off of a collaborative project that gathers the e-Mobility actors and aims for ensuring a successful roll-out of the new EV charging services in the French market.

 

Towards an open and fair market with a reference architecture

The Mobena initiative’s objective is to ensure a successful deployment in the French market of the ISO 15118 services (Plug and Charge -PnC- and smart charging) in a harmonized way with Europe.

To do this, adopting a reference architecture, from technical and organizational point of view, is key. Such architecture shall ensure interoperability and enable an open and fair market between all EV actors and allow end-users and operators to freely select their providers.

A first technical feasibility verification

Atelier recharge VEDECOM vu de haut

In preparation for the event planned on June 2nd, the Mobena initiative partners tested the technical feasibility of the Certificate Trust List (CTL) as a solution for Plug and Charge (PnC) interoperability between multiple PKI.

On March 11th 2021, VEDECOM hosted a Workshop for this objective at mobiLAB with the contribution of Freshmile, GIREVE, Hager, Groupe Renault, Stellantis, SAP Labs, Thales et Trialog
