Battery Management System Testing

CHALLENGE

Our team conducted a preliminary testing phase where the essential functionalities of the battery management system were verified to ensure that it's stable enough for more in-depth testing.

Their approach involved the use of the smoke test technique to determine whether the BMS could perform essential tasks and meet predefined criteria.

OUTCOME

During the smoke test, they focused on key aspects, such as:

Executing manual testing in order to validate the behavior of the software;
Identifying the issues and creating problem reports/tickets;
Generating reports in order to validate the smoke test;
Creating Test Cases to cover the functional requirements.

The BMS basic functionality was thoroughly verified before proceeding with the release, bridging the gap until automated tests were prepared.

Responsibilities

Conducting checks on fundamental functionality, including performing a smoke test
Making the critical decision to proceed with the software release based on the results
Checking the integrity of the automated test cases and validate their consistency with the written test cases
During the testing phase, the following topics were under the team members’ responsibility:
- Battery Escalation (Limp Mode, Cell Protection)
- System Initialization
- BUS Communication
- Data Input and Output
- UDS Diagnostics
- Error Management
- Flashing the Software on the boards
