Product: HIL Component-Level Testing for Battery Management Unit (BMU)

Client Challenge:
The client required support in reproducing OEM-reported temperature-related DTC issues within a HIL environment while improving automation and execution efficiency for System Test (SYS.5) activities.

RSB Solution:

• Configured HIL component-level testing environment for BMU validation
• Worked with High Power network simulators and Vector VT toolchain (CANoe.DiVa, vVIRTUALtarget, vTESTstudio)
• Performed fault injection testing and customer issue reproduction activities
• Updated sensor models using Python-based lookup tables to simulate realistic temperature noise observed in OEM logs
• Automated test suite execution using Python scripting for remote and overnight/weekend testing
• Supported test automation and validation activities in line with ASPICE SYS.5 processes

Delivered Results:
The project delivered improved sensor model behavior, automated HIL test execution capabilities, and successful reproduction of temperature-related issues previously difficult to replicate.

Client Value:
The client gained faster and more efficient validation workflows, improved reproducibility of real-world BMU issues, and enhanced delivery performance for System Test activities through automation and remote execution support.
