Introduction
As electric vehicles evolve, the complexity of their energy systems increases. Battery Management Systems (BMS) are critical for safety, performance, and range optimization. Ensuring their reliability requires precise, repeatable, and automated testing workflows. Sigma’s In-House team supported the development of such workflows, enabling efficient validation of BMS software in a virtual testing environment.
About the Client
The client is a leading automotive manufacturer actively developing next-generation electric vehicles. With a strong emphasis on in-house R&D, they required robust and scalable test solutions for their evolving BMS software, solutions that could accelerate verification while maintaining traceability to system requirements.
Solution
Sigma’s In-House engineers delivered a complete test automation package for the BMS domain, working closely with the client’s R&D department. The scope included:
Analyzing software and system requirements
Defining structured, traceable test cases
Developing automated test scripts
Executing tests in a Software-in-the-Loop (SIL) environment
Analyzing test results and ensuring feedback integration
The solution was delivered as a standalone package while maintaining close collaboration with the client’s internal teams to align with evolving system needs.
Results and Deliveries
The project resulted in:
- A maintainable and reusable test framework for BMS verification
- Reduced manual testing effort through automation
- Improved test coverage and traceability from requirements to results
- Accelerated SIL-based validation cycles for BMS software
