dSPACE offers a complete solution for developing and testing new charging tech

The dSPACE DS5366 Smart Charging Solution offers auto manufacturers and providers of charging stations a complete solution for developing and testing technologies for smart charging. The solution adheres to international standards, guarantees interoperability, and supports developers of on-board chargers, charging columns, and, in the future, inductive charging systems, by offering a range of test options and dynamic models.

The central requirements for developing the DS5366 Smart Charging Solution include the integration of existing test systems and a test depth that can be adapted to customer requirements. Extensive manipulations are possible both at the electrical and at the protocol level. The dSPACE solution consists of a software part with an open model and a special hardware module for communication, according to ISO 15118, ensuring an adaptation to power line communication. Comprehensive logging of all communication events allows for manual or automatic checks of the intended behavior and compliance with the protocol specification, as well as performing diagnostics. It also supports the execution of conformance tests, according to the standard.

Typical applications include testing of onboard chargers, charging stations and communication modules. The DS5366 simulates a variety of charging stations in the lab, emulates communication errors, and ensures that the ECU functions without errors. In the same manner, it will also be possible to test the compatibility between the developed charging stations and numerous simulated vehicles during tests on the charging station.

Another focus area is the development of onboard chargers. If no software or hardware is available for charging communication during the development of a vehicle charge controller, the dSPACE solution can replace the vehicle ECUs or their communication controllers for testing in-vehicle prototypes.

In combination with dSPACE Automotive Simulation Models (ASM), the Smart Charging Solution becomes a turnkey application for EVs, including real-time high-voltage battery simulation. The models also include emulation of a charging station in which the charging voltage depends on the vehicle’s power consumption, which is determined by the vehicle’s charge control unit. If no charge controller is available, ASM lets users simulate a controller using a constant current constant voltage (CCCV) charging process. The demo models are prepared in such a way that all signals required for communication with the control units are available. This enables testing of the control algorithms and the interfaces between all devices, according to standards such as CHAdeMO, ISO 15118, and GB/T 20234.2.
