Ilia worked on the dalathegreat/Battery-Emulator repository, focusing on enhancing State of Charge (SoC) estimation for battery management systems. Using C++ and embedded systems expertise, Ilia introduced internal resistance compensation and updated lookup tables to improve SoC accuracy across varying operating conditions. The work included correcting SOC-to-voltage mapping logic and implementing a fallback mechanism to the BMS-reported SoC when cell count was unconfirmed, addressing robustness gaps during configuration. This firmware development effort resulted in more reliable battery modeling for QA, testing, and hardware validation. The depth of changes demonstrated strong skills in matrix-based estimation and defensive embedded programming.
