Plugged in to charging
20 August 2012
Developing conformance tests for charging e-vehicles is an issue growing in importance.
The German Research Institute of Automotive Engineering and Vehicle Engines Stuttgart (FKFS) and Vector Informatik are working together to develop conformance tests for charging communication.
The tests verify that communications between the vehicle and the charging station conform to the ISO 15118 and DIN 70121 standards. This lets vehicle and charging station producers and their suppliers develop and test their products independently.
FKFS provides a test environment for testing vehicles and charging stations independently of one another. The test environments cover charging by either alternating current or direct current. This eliminates the need to test every vehicle model series explicitly in conjunction with each and every charging station. The conformance tests allow FKFS to offer official acceptance tests. The infrastructure needed for this is already available at FKFS with charging stations for AC and DC charging.
Vector supplies the vehicle-side software modules for ISO 15118 and DIN 70121 communication. They serve as a reference for FKFS in developing the conformance tests. The modules are available as extensions of the AUTOSAR basic software MICROSAR IP for both AC and DC charging. Various automotive OEMs are already using this software in production development.
In addition, FKFS utilises the CANoe.IP development and test tool from Vector for test execution. When used together with VT System test hardware from Vector, test engineers get a complete tool chain; from test development to test execution.
