Integration of new flexibilities
into the energy markets
2 – 3 April 2025
in Aachen,
Germany
The international conference ‘Vehicle-to-Grid, Vehicle-to-Home & Smart Charging’ will take place in Aachen on 2 and 3 April 2025. The concepts of vehicle-to-grid (V2G), vehicle-to-home (V2H) and smart charging play a key role in the further development of electromobility and the acceleration of the energy transition.
Leading representatives from the vehicle industry, charging infrastructure development, the energy market and technology providers are working together on innovative, marketable solutions to optimally utilise the potential of electromobility.
The conference offers a platform to discuss technical advances, regulatory framework conditions and forward-looking business models. In addition, the effects of current trends in the energy industry on the integration of electromobility into the energy system will be highlighted. You can look forward to exciting presentations, practical discussions and an interdisciplinary exchange with experts from all over the world.
Smart Charging
Smart Charging refers to the intelligent charging of electric vehicles. The goal is often to reduce grid stress through measures such as peak shaving or valley filling and to consume locally generated renewable energy on-site. In short: the battery needs to be sufficiently charged by morning to cover the planned distances, with the exact time of charging during the night being irrelevant.
Vehicle-to-Home (V2H)
Vehicle-to-Home (V2H) pursues similar goals, but a bidirectional electric vehicle can also feed electricity into the home network. Homeowners can thus forgo a separate battery storage system, as the electric car essentially serves this function.
Vehicle-to-Grid (V2G)
Vehicle-to-Grid (V2G) takes this a step further by enabling electricity to be fed into the public grid. This opens opportunities such as arbitrage trading and the provision of ancillary services. Through the bidirectional connection of vehicle batteries to the power grid, local electricity grids can be stabilized. Electric vehicles act as mobile power storage units, contributing to grid stabilization without significantly impacting vehicle use.
Flexible energy markets
Flexible energy markets: Flexibility is a crucial component of a cost-efficient and stable power system. It allows for the temporal shifting of electricity consumption and generation, as well as energy storage. In this way, flexibility can minimize the need for grid expansion and prevent the curtailment of renewable energies, making a power system without fossil fuel plants achievable.

2.–3. April 2025 in Aachen, Germany
Conference as part of the Advanced Battery Power Conference 2025
Six focus topics along the value chain:
01
Real-world projects
The conference places great emphasis on the practical implementation of ideas, which is why the “Practical projects” session is dedicated to projects that have already been realised. Here, players from all areas of the value chain share their experiences from field tests, practical projects and the commercial operation of bidirectional vehicles.
02
Charging infrastructure
The charging infrastructure is experiencing dynamic and rapid development cycles, and a modern charging point has long been capable of much more than just supplying electricity. Charging infrastructure provides the central communication interface between vehicles on the one hand and home energy management systems, grid operators, aggregators, etc. on the other. Especially in the bidirectional area, direct current connections are often used, which is why the charging points must provide authorised alternating current for the grid. In this session, charging infrastructure manufacturers, operators and other players in the charging infrastructure ecosystem will speak.
03
Vehicles
Bidirectional charging is transforming the vehicle from a pure consumer to a player in the electricity market of the future. In order to successfully implement new applications and business models, vehicle manufacturers are facing new challenges. Vehicle batteries must be able to provide more cycles in an energy-efficient manner and new communication interfaces must be implemented safely – all without jeopardising the primary purpose of the vehicle: To transport people and goods reliably. In this session, automotive companies will share their experiences and current ambitions in this area.
04
System integration
With vehicle owners, aggregators, energy companies, backend operators, vehicle manufacturers, grid operators and many more, there is a wide variety of players in the field of bidirectional charging. In this session, we will look at concepts on how all players can be integrated into a common value chain and thus achieve system integration.
05
Grids and Data
The question of whether electromobility will overload or overload the electricity grids is a major concern for many citizens. The background to this is that expanding the electricity grid often takes years or decades and sometimes fails due to resistance from the local population. Electromobility, on the other hand, will become established within a few years and is therefore much faster. During the conference, our speakers will show how the grids can still be stabilised and not overloaded by electromobility.
06
Smart & Dynamic tariffs
The integration of vehicle-to-grid technologies makes it possible to use electric vehicles (EVs) not only as a means of transport, but also as mobile energy storage devices. Intelligent and dynamic tariffs play a key role in efficiently controlling energy flows between vehicles and the electricity grid. Such tariffs adapt to exchange electricity prices and, in some cases, grid conditions the day before or in real time. This allows users of electric vehicles to benefit from attractive prices when they feed energy into the grid or charge at favorable times. At the same time, these tariffs promote grid stability, reduce peak loads and enable optimized integration of renewable energies into the energy system. This is an important step towards the sustainable and economical mobility of the future.
Interactive exchange between business and science
Each programme session ends with a time slot for your personal questions and discussion with the speakers and participants. The speakers will be available for discussions during the conference.
The accompanying public poster session will convey scientific content, research results and ideas in a direct dialogue. The researchers will be at their posters and will be available to answer visitors’ questions. The integration of the conference into the international Battery Power Conference offers a broad spectrum for encounters and intensive dialogue.
If you think about bidirectional charging as the future of electromobility, the following terms automatically come to mind:
Vehicle to Grid (V2G), Vehicle to Home (V2H), Smart Charging (V1G), and Vehicle-to-Building (V2B) are different operating modes related to (bidirectional) charging.
For the grid connection of the electric car, charging infrastructure with Combined Charging System (CCS) or CHAdeMO standard is required, the former in combination with the ISO 15118-20 communication protocol.
Using the Open Charge Point Protocol (OCPP) version 2.0, back-end operators, aggregators and energy companies can interconnect the individual electric vehicles capable of feeding energy back into the grid to form virtual power plants and thus contribute to grid stabilisation.
Distribution system operators and transmission system operators are very interested in opening up the control reserve market for electric vehicles so that they can also provide control reserve in the same way as stationary storage systems.
In order to bring these concepts to market maturity, issues relating to battery ageing, regulation, digital resilience and (open) protocols still need to be discussed.
This means that OEMs (vehicle manufacturers), network operators and end customers (vehicle owners) as well as industrial companies and service providers that operate and charge vehicles are all involved. Billing companies and lawyers must also be involved. This shows the complexity of the issue.
From an economic and ecological point of view, it seems extremely attractive to use unused or barely used and expensive energy storage capacities to stabilise the electricity grid. The construction of power lines can thus be partially avoided and periods without wind and solar yield can be bridged in the best case. The legal framework conditions are important for this.
Diese und weitere Themen werden auf der hier angebotenen Tagung V2G behandelt.
The conference will take place parallel to the international conference Advanced Battery Power. The English-language keynote speeches, the exhibition and the poster session are equally accessible to both groups of participants. It is even possible to attend the parallel sessions of the other conference.
