In this use case, the charging station is simulated to test onboard chargers of electric vehicles and their behavior when connected to different simulated charging stations.
There are many manufacturers for electric vehicles (EV) as well as for charging stations. At the same time, charging infrastructures also differ significantly depending on the region. To manage this diversity, the communication between the EV and the charging station is specified in several standards, such as CHAdeMO, ISO 15118, and GB/T, all of which must be taken into account when testing onboard chargers for electric vehicles worldwide. For testing charging technologies, the DS5366 Smart Charging Interface from dSPACE is connected to a HIL simulator via CAN FD. For this use case, a SCALEXIO Customized System is equipped with a SCALEXIO LabBox, a DS6001 Processor Board, a DS6101 Multi-I/O Board, and a DS6341 CAN Board as well as power electronics and safety components, which are typically installed in a charging station. The DS5366 Smart Charging Interface simulates the communication controller of the charging station according to ISO/IEC 15118-1, -2, -3, DIN SPEC 70121, SAE J1772, and IEC 61851-1. Using Simulink® models, which are included in the Smart Charging Solution from dSPACE, you can simulate different charging stations and their behavior, including timing and message manipulation. The actual communication between the electric vehicle and the simulated charging station is done via the control pilot (CP).
