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.

In this thesis are investigated methods to manage shared electric autonomous taxi urban systems under an online context in which customer demands occur over time, and where vehicles are available for ride-sharing and require electric recharging management.

We propose heuristics based on problem decomposition which include road network repartition and highlighting of subproblems such as charging management, empty vehicle redistribution and dynamic ride-sharing.

The set of new methods for empty vehicle redistribution is proposed, such as proactive, meaning to take into account both current demand and anticipated future demand, in contrast to reactive methods, which act based on current demand only.

We provide reinforcement learning in different levels depending on granularity of the system.

We propose station-based RL model for small networks and zone-based RL model, where the agents are zones of the city obtained by partitioning, for huge ones. The complete information optimisation is provided in order to analyse the system performance a-posteriori in offline context.

The evaluation of the performance of proposed methods is provided in a set of road networks of different nature and size.

The proposed method provides promising results outperforming the other tested methods and the real data on the taxi system performance in terms of number of satisfied passengers under fixed fleet size.
