Smart Charging Solution

Developing and testing intelligent charging technologies

The new Smart Charging Solution is a key solution for developing and testing technologies involved in the electric vehicle charging process. The combination of hardware and software components offers comprehensive test possibilities.

  • Support of all common charging standards, such as ISO 15118, DIN SPEC 70121, IEC 61851-1, CHAdeMO, and GB/T
  • High degree of customization as well as fault injection and logging capabilities
  • Seamless workflow with Simulink®

For ISO 15118- and IEC 61851-1-based communication, the Smart Charging Solution features a special hardware component, the DS5366 Smart Charging Interface.

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 software part 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, 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 get 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, e.g., for parametrization as well as electrical and timing manipulation.
