User-friendly, secure, and interoperable EV charging

That's the very purpose of V2G Clarity's existence.
We accelerate the world's transition to a future-proof EV charging infrastructure for a more sustainable way of living.

Fossil-fuel based transport makes up a quarter of Europe’s greenhouse gas emissions, crying out for a need for electric vehicles worldwide. We’ve all seen the positive effects on air pollution when diesel and gasoline cars suddenly stand still — globally.

EVs are our best chance to a fossil-free, greener transport. Let’s make sure the driving and charging experience is a child’s play. We help you tackle the complexity of smart EV charging so you can serve your customers with a great user-experience.

Our Values

With our expertise along the complete value chain of charging electric vehicles, we dedicate our work to overcoming the technical challenges of innovative EV charging infrastructure.

Our solutions are based on future-proof communication standards and protocols like ISO 15118 and OCPP 2.0.1.

We strongly believe in sharing knowledge through high quality educational content and open-source software to support existing and new market players in the e-mobility industry.

We strongly encourage collaboration and open innovation with open-source software to develop solutions that pave the way for a sustainable, environmental-friendly means of transportation through EVs.

We use our decade of experience in implementing future-proof technologies like ISO 15118 and make it available to the public — so you can focus on your core business.

Our Story

A small selection of landmarks that shaped our expertise in e-mobility and standardization

Partnership with CharIN e.V.

Established as the accredited on-site training partner of the Charging Interface Initiative (CharIN e.V.) on the Combined Charging System (CCS) and ISO 15118.

ISO 15118 Manual

Published an e-book for beginners and experts alike to reduce the steep learning curve of ISO 15118 with a comprehensive and easy-to-understand guide. This eBook has fast become standard literature in the e-mobility industry.

Chair of the Plug & Charge Working Group at DKE

ISO 15118 only specifies the communication between EVs and charging stations, not the market roles, interfaces, and certificate policies needed to bring the user-friendly and secure Plug & Charge feature to life. This working group published the VDE application guide VDE-AR-2802-100-1, which has since served as a de facto standard for the industry.

Creation of V2G Clarity

The brand V2G Clarity was established, known for its unparalleled expertise on ISO 15118 and related communication technologies as well as our consultancy services and (open-source) software.

ISO 15118 Goes Open-Source

Published RISE V2G – the only open-source implementation of ISO 15118. This software comprises all features of ISO 15118-2, both for EVs and charging stations. RISE V2G dramatically accelerated the uptake of ISO 15118 within the e-mobility industry and continues to be maintained and refined.

SaaS For E-Mobility Industry

Before the story of V2G Clarity began in March 2016, the founder gained intensive insight into the e-mobility industry, implementing comprehensive software-as-a-service solutions for charge point operators and e-mobility service providers

Our founder joined the ISO 15118 standardization body

Dr Marc Mültin joined the newly formed ISO and IEC Joint Working Group (JWG), a standardization body for defining the ISO 15118 communication interface. V2G Clarity’s founder has been an active member ever since, co-authoring parts of ISO 15118.

Research on ISO 15118

Dr. Marc Mültin’s Ph.D. study in Computer Science at KIT led to the first publicly available literature about the inner workings of ISO 15118 – his Ph.D. thesis “Das Elektrofahrzeug als flexibler Verbraucher und Energiespeicher im Smart Home” (engl.: “The electric vehicle as flexible consumer and energy storage in the smart home”)

Our Founder

V2G Clarity has a strong academic background. Its founder, Dr. Marc Mültin, received his Ph.D. in Computer Science in 2014 from the Karlsruhe Institute of Technology (KIT), one of Germany’s leading research institutions known for its alumni of inventors and entrepreneurs. In the same year, he published his Ph.D. thesis with revolutionary approaches to two key challenges in the EV space. Firstly, integrate EV into a smart home’s energy management system, incorporating ISO 15118 throughout. Secondly, charge the EV when green energy is available (e.g. through solar panels on the roof) and use the stored energy in the EV’s battery to power the home when needed.

Open innovation and sharing knowledge has been a key principle of Dr. Marc Mültin’s work. His strong teaching background at the university through to implementing open-source software to meet the needs and challenges of the e-mobility industry, continues to be a strong pillar of all the services and products offered by V2G Clarity.

World travel, and a passion for discovering different cultures and nature, be it Argentina’s Iguazú Falls, Iceland’s Aurora Borealis, New Zealand’s trails and mountains, the beautiful island of Bali, or the lovely forests in his hometown, to name just a few, has deeply impacted Dr. Marc Mültin’s drive to do everything in his power to protect nature and mitigate climate change through innovative and sustainable technology.
