Hardware and Software

The Smart Charging Solution includes hardware and software and can be easily integrated into your test setup. It supports all common charging communication standards.

The hardware component, the DS5366 Smart Charging Interface, comes as an isolated interface between the hardware-in-the-loop (HIL) simulator and the electronic control unit (ECU). It provides a CAN FD interface for connecting to the HIL simulator as well as USB and Ethernet interfaces for protocol tracing and data logging.

The Smart Charging Interface Software as the basic software component of the Smart Charging Solution includes a Simulink® model, ControlDesk layouts, and a DBC file that describes the CAN FD communication. The Simulink model supports all common charging communication standards, such as ISO 15118, DIN SPEC 70121, CHAdeMO, ChaoJi-2, and GB/T. It includes a user interface for parametrization and allows for the connection and simulation of power electronics components. By using the ControlDesk layouts, you gain an overview of all the relevant electrical information, the messages involved in the charging communication, and the communication status. You can also use the layout for configuration purposes, for example, for parametrization as well as electrical and timing manipulation.

For a comprehensive set of fault insertion options, the Smart Charging Plug Simulator can be added to the Smart Charging Solution. It supports all common charging standards, including the CharIN CCS Test System (CCTS) recommendation. The extension lets you emulate and manipulate the electrical networks related to connectors, cables, and communication signals.

The Smart Charging PlugAndCharge Software Module lets you test advanced features as described in the ISO 15118-2 charging communication standard, including plug-and-charge (PnC) and value-added services (VAS). These features require TLS encryption and certificate handling, which are both supported by the dSPACE test solution.

Simulating Charging Stations
