Overview

Interoperability – activities at CharIN

Charging Interface Initiative e.V. - abbreviated to CharIN e.V.

registered association founded by Audi, BMW, Daimler, Mennekes, Opel, Phoenix Contact, Porsche, TÜV SÜD and Volkswagen

based in Berlin

open to all interested parties

The primary aims are:

To develop and establish the Combined Charging System (CCS) as the standard for charging battery-powered electric vehicles of all kinds

To draw up requirements for the evolution of charging-related standards (e.g. inductive and pantograph connection)

To develop a certification system for use by manufacturers implementing the combined charging system in their products

Modular and scalable CCS Test System offered from different vendors


Modular and scalable

Usage of HW (communication, power transfer) and SW (test cases, test executor) from different vendors possible by a common defined interface

Broad range from small CCS Test System (communication only) to big CCS Test System (full power support) possible

CCS Test System subsequently expandable to cover all SUT

Adaption of power transfer HW (sink or source) according to HPC power class of SUT possible

Definition of CCS Test System is only minimum requirement

Offered from different Vendors

Decision of customer which CCS Test System to use

Further usage of already available test systems possible, no complete reinvest necessary

Working with well-known and established test systems allows faster time to market
