Get an overview of the electric mobility topics. What has already been achieved? Where does work still need to be done?

Users see electric mobility as an integrated offering. The NPE’s fields of activity reflect this perspective and include vehicle technologies, energy and the environment, urban planning, norms and standards, information and communication technologies and education and training. The interfaces between the topics are wide-ranging, with highly qualified experts developing innovative vehicle technologies, and information and communication technologies being used to produce customer-friendly payment models for charging. Through research and development, science and industry are creating the basis for an attractive offering. Ultimately, it’s the satisfaction of and acceptance by users that counts, and that’s why the NPE is promoting these topics.

Norms & standards

International norms and standards ensure user-friendliness and security for investment in vehicles and charging infrastructure. They form the framework in which electric mobility is developed and ensure that users can charge their vehicles at every charging point without difficulty, including abroad.
The Combined Charging System (CCS) is a uniform charging system in Europe and the United States. It enables users to provide their vehicles with up to 43 kilowatts of energy at standard charging points and potentially up to 350 kilowatts of energy at fast charging points. All users need to do is to connect their vehicle to a charging point. These exchange information independently on factors such as charging status, using the standardised communication in the CCS.
International standards also need to be developed at an early stage for future charging systems. This applies in particular to cable-free inductive charging, where electric vehicles are powered using contactless technology and a magnetic field.


The Charging Interface Initiative e. V. – or short: CharIN e. V.  – aims at developing and establishing the Combined Charging System (CCS) as a worldwide standard for battery-powered electric vehicles of all kinds. The CCS is currently the only charging system worldwide able to cover all charging scenarios with one single product. CharIN e. V. is also drafting requirements for standards for charging-related matters, and is developing a certification system for manufacturers implementing the CCS in their products.

CharIN e. V. is a registered association founded by Audi, BMW, Daimler, Mennekes, Opel, Phoenix Contact, Porsche, TÜV SÜD and Volkswagen. It is open to all interested parties, encouraging their participation.
