Worked on the dalathegreat/Battery-Emulator repository to deliver independent per-battery cell data display, enabling accurate monitoring for dual and triple battery configurations. Addressed a key issue in the Cellmonitor component by isolating cell data per battery instance, which resolved cross-instance data leakage and ensured each battery’s health and performance metrics were reported correctly. The solution involved C++ programming and embedded systems expertise, with a focus on battery management system data modeling. Employed Python object-oriented programming for testing and validation, and utilized Git-based workflows to document and verify changes, resulting in more reliable dashboards and streamlined multi-battery scenario debugging.
