Validation of EV BMS Functional Safety
Project Scope
- 546 TSRs and ~20,000 test cases to be executed and validated for 13 safety functionalities (ISO26262)
- Automation test scripts to be created for all test cases and to be run at customer location
- Execution of test scripts/cases on ETAS lab car with simulated vehicle
Business Challenges
- Dependences from vendors on software variables, thresholds, calibration data and signal mapping information
- BMS basic knowledge was there but having functional safety ISO26262 was new
- Performing ~20k test cases manually is time taking and there are lot of misses possible
ARi’s Solutions
- Test cases written in English in excel reformatted to be able to understand and configurable by automation tool framework internally developed
- No manual creation of test scripts and execution is necessary with the automation framework created
- Reports generated for all test cases with mapping of TSRs and requirements to validate complete coverage
ARi’s Value Proposition
- Improved coverage of various features in functional safety of BMS with automation framework, reducing lot of time and effort
- Made the automation framework generic to be able to use for next software releases, not just for functional safety and BMS but for any system and software validation on any HIL test bench
