Worked on the dalathegreat/Battery-Emulator repository to enhance the reliability of BMW-I3 battery emulation, focusing on data integrity within embedded systems. Addressed a critical bug in C++ code by correcting the cell voltage indexing in the receive_can_battery2 function, ensuring accurate logging for the second battery and reducing the risk of data misinterpretation during integration testing. Leveraged expertise in Battery Management Systems and CAN Bus protocols to deliver a targeted fix that improved emulator fidelity. Emphasized best practices in debugging, code review, and collaborative workflows, contributing to more robust validation processes and supporting quality assurance readiness for downstream test suites.
