An ISO/IEC 15118 conformance testing system architecture

A major goal for the ISO/IEC15118 standard for controlling the charging process for electric vehicles is the simplicity and reliability of use. Severe threats for a simple use are implementations of the standard which are not interoperable to each other. A traditional approach to reduce this threat is the setup of testivals between all implementations to explicit test interoperability. However this approach is complex and expensive as it requires extensive test and the coordination between all implementers. The project eNterop takes a different approach to enable a broad acceptance of the ISO/IEC 15118 and IEC 61851 specification on the market and to facilitate a large number of implementations. It defines conformance tests which can be fully automated. This is a quite new approach for machine to machine interface specifications which not only cover communication but also power interfaces. With that implementers can independently test their protocols including the power flow control and increase the likelihood of interoperable implementations without expensive testivals. This paper presents the approach of conformance tests for combined communication and power interfaces.
