Test system emulates EV charging stations
Development tool provider dSpace is expanding its range of intelligent charging technologies with the "Smart Charging Station Emulator". It enables manufacturers of electric vehicles and suppliers of battery systems to test their new developments with different technical charging standards and protocols, simulate errors, and speed up the development process in line with the requirements of international markets.

The Smart Charging Station Emulator is based on the Smart Charging Solution from dBase, a solution for testing onboard chargers, charging stations and communication modules, which was already introduced to the market last year. Other components include a real-time simulator, a dynamic and expandable model that runs on the simulator, and a power supply that enables DC charging and discharging at a maximum of 85 kW. This means that Vehicle2Grid scenarios can also be represented.

All components are housed in a robust, mobile rack. This means that the system can be used not only in the laboratory but also for tests on prototype vehicles in workshops. Safety is ensured by features such as automatic cable recognition, coupling of communication and charge release, insulation monitoring and emergency stop switches.

The system supports international standards for charging communication such as ISO 15118 and DIN SPEC 70121, GB/T 27930, GB/T 18487 and CHAdeMO, and thus emulates a wide variety of charging stations and charging scenarios in real time. New charging standards such as CHAdeMO 3.0 or ChaoJi can be easily re-implemented.

The Smart Charging Station Emulator supports AC charging up to 63 A and DC charging up to max. 200 A or max. 85 kW and is flexibly adaptable to customer-specific charging supply requirements. In addition, the system offers numerous options for varying the electrical parameters and communication.
