Interoperability with Charging Infrastructure-Field Test on the Test Bench

摘要

When charging electric vehicles, interoperability problems can arise between the vehicle system and the charging station, even if the components comply with the respective standards and should theoretically be compatible. AVL has developed a test methodology for validating the charging function that is based on an extensive test case database and starts early in the system development phase. The scope of cost-intensive field tests can thus be significantly reduced. Validation of the charging function and the associated interaction between vehicles, both electric and plug-in hybrid, and the charging infrastructure experiences high prioritization due to the relevance of the charging function. In technical jargon, this interaction is called interoperability (IOP). Previous experience has also shown that problems with charging can often occur due to the high level of functional complexity in vehicles and the inhomoge-neous charging infrastructure. This situation has caused the manufacturers of vehicles and charging stations to pursue the topic of interoperability with high priority and to expend the appropriate validation effort.
