CharINs view on adaptors within the Combined Charging System (CCS)
To make a clear statement this paper explains the challanges with using adaptors and why the CCS should work without them.
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.
Position Paper on the revision of the Energy Performance of Buildings Directive
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.
"ACEA position and recommendations for the standardization of the charging of electrically chargeable vehicles", May 2012
ACEA, the European Association of Vehicle Manufacturers, has selected the Combined Charging System as the future standard interface for all electric vehicles.
ACEA confirmed that from 2017 onwards, at the latest, ALL new electric vehicle types will implement the Combined Charging System by using Type 2 and Combo 2 based AC/DC charging interfaces.
All the current members of ACEA support the Combined Charging System for Europe: BMW, DAF, Daimler, Fiat, Ford of Europe, General Motors Europe, Hyundai Motor Europe, Jaguar Land Rover, MAN, Porsche, PSA, Renault, Scania, Toyota Motor Europe, Volkswagen, Volvo Cars, and AB Volvo.
SAE International Releases New Fast-Charging Combo Coupler Standard (SAE J1772) for Plug-In Electric and Electric Vehicles, Oct. 2012
WARRENDALE, Pa., Oct. 15, 2012 - SAE International’s much-anticipated technical standard for plug-in hybrid electric vehicle (PHEV) and electric vehicles (EV) has been approved and published.
Developed in a consensus environment by more than 190 global experts representing automotive, charging equipment, utilities industries and national labs, “J1772™: SAE Electric Vehicle and Plug in Hybrid Electric Vehicle Conductive Charge Coupler” enable charging time to be reduced from as long as eight hours to as short as 20 minutes.
