This position paper represents a collection of practical observations with the overall goal of enriching the future development of the charging infrastructure with customer-oriented solutions. These should be taken into account in the planning and construction by future operators across all industries.

CharINs view on adaptors within the Combined Charging System (CCS)

CharIN Position Paper about Automatic Connection Device Interface for automatic conductive charging

As autonomous driving is about to hit the consumer market, which enables new possibilities for a fully automatic customer experience, there is the need to harmonize the requirements and to provide guidance. This position paper gives recommendations for two different forms of automatic connection devices for passenger cars: ACDS (Automatic Connection Device for the conventional Side connection interface) and ACDU (Automatic Connection Device for vehicle Underbody connection).

CharIN implementation guide to Plug and Charge in the context of ISO 15118

CharIN Focus Group Charging Communication worked out a detailed implementation guide for the charging communication feature “Plug and Charge” of ISO/IEC 15118 communication protocol.

Grid Integration - Mission Statement

The Focus Group Grid Integration identifies technical issues, harmonizes approaches between the involved industries and evaluates technical and economical potentials. As a result, this mission paper was developed. It shall illustrate the position of CharIN towards grid integration with the Combined Charging System and provides an outlook for future developments.

CharIN Levels Grid Integration

CharIN presents the perspective on the different levels of grid integration with the following figure.

Position of CharIN towards new standards


CharIN endorses increasing charging currents for EVs up to 500 A

As part of its ongoing process to provide guidance and support for the development of a battery electric vehicle charging eco system the CharIN Association endorses the initiative to increase the charging currents for EVs up to 500 A . With this statement CharIN ensures to fulfil the demands of future use cases.


This document introduces power classes with voltage and current limits to assure interoperability between electric vehicles and charging stations and allow conformance testing.


Members of CharIN worked out an open specification sheet for an interoperable wireless power transfer system for electric vehicles within the scope of CCS.

The work is based on the available position paper and contains proper technical specifications to make interoperable inductive charging possible. Members of CharIN have full access to the document „CharIN industry statement on interoperable wireless power transfer“.


CharIN industry statement on interoperable wireless power transfer

This industry statement covers the most relevant technical objects to define the requirements for an interoperable wireless power transfer for inductive charging of electric vehicles. Therefore magnetic and electric interoperability testing as well as test systems referenced in SAE J2954 are described. The positioning, the safety concept and a common ground assembly position in the parking slot is considered. The document will be the baseline for an open specification for all involved parties.

CharIN Support of ISO/IEC 15118

CharIN prefers ISO/IEC 15118 as the communication protocol between the electric vehicle and the charging station. To affirm this position, the benefits and efforts to develop this standard are pointed out in the position statement. Furthermore, the additional use cases which are also covered by the protocol are highlighted in the document.

Electric Fuel Labelling

CharIN e.V. wants to give a guideline for organizations and authorities who need to create electric fuel labels to help drivers of electric vehicles to identify (fast) charging stations and the right CCS connectors for their particular vehicle.
CharIN e.V. proposes that all signs for EV charging stations (e.g. for road signs) should be comparable and easy to identify. Labels for road signs should be similar to current fuel station labels, so that drivers can recognize them easily, even when driving at highway speed limits. Additional to the labelling of road signs, CharIN encourages manufacturers of (fast) chargers to label their charging stations with symbols for CCS charging connectors, such as a colour code and an identification number (ID). The proposed label is a combination of the output shape and an optional colour code.
All in all this Position paper on “Electric Fuel Labelling” helps to create a guideline regarding customer journeys and provides drivers of electric vehicles with a consistent user experience.

CharIN recommendation: A harmonized connector approach per geographical region facilitates EV market uptake

CharIN is dedicated to support and establish the Combined Charging System (CCS) as the standard for charging Battery Electric Vehicles (EVs) of all kinds. As there are different CCS connector types used in the different regions of the world, CharIN recommends a harmonized CCS connector approach per geographical region to allow cross border travelling. The CharIN recommendation can be downloaded here.

CharIN’s perspective on Inductive Charging

To underline its “one system for all” target, CharIN has decided to incorporate inductive charging into its global approach.

The current revision of the Energy Performance of Buildings Directive (EPBD) is as an opportunity to accelerate the development of charging infrastructure of electric vehicles in Europe. CharIN states its position in the paper, which can be downloaded here.

DC Charging Power Classes

DC Charging Power Classes provide specific information on the classes of high power charging. A minimum power is guaranteed in each class. They present a visibility of quality and performance identification for customers of high power charging for electric vehicles.

Industry Statement on Charging Infrastructure

The CharIN Vision: Developing and establishing the Combined Charging System (CCS) as the global standard for charging battery powered electric vehicles. Charging infrastructure plays a pivotal role for the market uptake of EVs, and new technological developments need to be integrated quickly in order to shorten charging times. 

CharIN Guidance: Information displayed on charging stations

Full customer satisfaction during the charging process is pivotal, and thus is key for the market uptake of EVs. Providing relevant and accurate information to the customer while charging is therefore of high importance. For this reason CharIN e. V. has published a guidance paper with detailed recommendations on the charging parameters to be displayed to the customer. The guidance paper is available for download here.

"Directive 2014/94/EU of the European Parliament and of the Council of 22 October 2014 on the deployment of alternative fuels infrastructure", October 2014

The European Parliament enacted the directive on the deployment of the alternative fuels infrastructure in April 2014, representing a major milestone supporting the rapid adoption of the Combined Charging System (CCS).

From November 18, 2017 onwards, the member states of the European Union must equip their fast charging stations with CCS. They may continue to operate their existing charging infrastructure, but must at least provide CCS (the connector Combo 2 for DC and the connector Type 2 for AC charging) in their expanded or new infrastructure.
