Chroma ATE introduces the Chroma 8620 OBC and DC-DC Converter Power HIL Testbed for testing electric vehicle charging systems and powertrain components. Hardware configuration can be adapted according to DUT specifications, with options including a programmable DC power supply, programmable DC electronic load, digital power meter, and oscilloscope. Chroma 8620 can be applied to different system architectures and boasts expansion and sharing of the platform.

Chroma 8620 is specially designed for research and development of on-board chargers (OBC) or DC-DC converters. Its flexible software provides user interfaces for operation and monitoring of manual and automated test functions and automatically generates comprehensive test reports. Users can quickly conduct large numbers of repeated tests, improving test coverage and efficiency.

Chroma 8620 supports the loading of Altair Activate models or Model-Based vehicle models so that users can continuously apply existing vehicle models, saving the trouble and time of redevelopment. Moreover, CAN HS/FD and LIN communication interfaces are able to load DBC and LDF communication files.

For functional testing, Chroma 8620 can simulate normal operating conditions of the DUT in a real vehicle environment. It can also simulate abnormal operating conditions, including communication abnormalities and signal faults (Open Circuit, Short to Ground, Short to Battery, Pin-to-Pin Short). This serves to avoid possible hazards during the charging process or when the vehicle is on the road. Laboratory simulation testing not only diminishes the risk of accidents in the actual vehicle, but also eliminates the high costs associated with using real vehicles for testing.
