Dr.-Ing. Marc Mültin

Freelance pioneer in e-mobility

I studied computer science at the Karlsruhe Institute of Technology (KIT) and received my doctorate there with the question of how an electric car capable of bi-directional energy transfer can be integrated into the energy management of a smart home. After that I worked for the company Chargepartner GmbH, which offered comprehensive software-as-a-service solutions for charging and billing the loaded energy of electric vehicles.

I have been self-employed since March 2016 and, in addition to my activity in research projects, I am available with my expertise in the field of e-mobility to help companies interested in the ISO 15118 standard to face their challenges.

Standardisation and committee work

As part of my membership in the DIN standards committee, I have actively promoted the standardisation of the communication protocol ISO 15118 from the outset and have written parts of ISO 15118-1 and 15118-2. Currently I am also intensively involved in the creation of edition 2 of ISO 15118.

In addition to my standardisation activities, I work as part of the DKE Working Group DKE/AK 901.0.115 "Information security in  electric mobility" as a working group chairman in shaping a VDE application rule for certificate handling as part of ISO 15118.

Giving a standard wings with open source

RISE V2G serves as a fully-featured open source reference implementation of the ISO 15118 standard. Companies, research institutions and other interested parties already implementing the standard can use this software as a receiver for their own implementation of an ISO 15118-compliant charging station or even an electric vehicle.

Knowledge is a precious resource. Because it increases as soon as it is shared amongst each other.

Durch meine Mitarbeit an Forschungsprojekten zur E-Mobilität bereite ich den Weg für die elektromobile Zukunft

Aktive Projekte


Electric vehicles exchange data both while in motion and during the charging process. Total data security and data protection must be guaranteed. This applies to both charging and the billing process. It applies as a principle for green energy charging when we connect electric vehicles to the Smart Grid, and also when we want to use value-added services.

The international standardisation system has created a basis for communication between an electric vehicle and the charging infrastructure in the form of international standard ISO 15118, which is already in place. The process chain and the value chain for charging processes and value-added services also involve billing systems and other players, however. These include third-party providers, energy providers, network operators, fleet managers, vehicle manufacturers, and services such as mapping services. Communication in this area still has not been standardised. In addition, standardisation does not yet cover safeguarding the vehicle, the charging unit itself, or the linked back-end and billing systems. These are the gaps that the DELTA project is designed to close.

The objective of the SeDaFa project (self data protection in the networked vehicle) is to develop solutions for the data privacy of drivers and passengers that vehicle manufacturers and infrastructure providers as well as the developers of car apps can use to make their business model data protection friendly. Car users should be informed transparently and clearly of which data can be sent and used for what purposes – vehicle users can use this as a basis to decide which data they wish to disclose. Thus, the data flow should not be completely prevented, but rather an access to vehicle data should be ensured that provides data protection. To achieve this, experts from different disciplines work together in the SeDaFa project who take into account not only technical, but also legal aspects and the user friendliness of the solutions to be developed.


Completed projects


In the joint project "Intelligent Zero Emission Urban System" – iZEUS –partners from research and industry banded together to advance research, development and practical demonstration in the "smart traffic" and "smart grid" areas.
In the "smart grid" sub-area, the Fraunhofer Institute for Systems and Innovation Research (ISI) and for Solar Energy Systems (ISE) collaborated to investigate grid integration concepts for electric vehicles and renewable energy. A bidirectional charger with an integrated function for real-time analysis of distribution networks was developed for this purpose and tested with an Opel Meriva electric vehicle at the Energy Smart Home Lab of KIT. Due to the fluctuating input from renewable energy sources in the power grid, such an intelligent, two-way exchange of information during the charging process is necessary in order to avoid bottlenecks in the distribution network. By means of a stationary lithium-ion battery storage, renewable energy is to be integrated into the energy system in the future and the control power, voltage and load in the network will be controlled automatically. Due to the efficiency of the system, user charging costs can also be reduced and emissions resulting from electromobility can be prevented due to the energy savings.

As part of this project, my first prototype of the ISO 15118 implementation came to fruition, which was later developed further into the open source project RISE V2G.


MeRegioMobil was part of the support programme "ICT for electromobility", which was funded by the Federal Ministry of Economics and Technology in partnership with the Federal Ministry for the Environment, Nature Conservation and Nuclear Safety. The objective of "ICT for Electromobility" was to develop and test ICT-based key technologies and services for the operation of vehicles and fleets as well as the integration of electromobility in energy and transport networks.
This funding priority of the federal government was closely tied to the the BMWi's E-Energy flagship project (http://www.e-energie.info/).
