Developed and integrated the Tesla DC-DC Converter Metrics feature for the dalathegreat/Battery-Emulator repository, expanding the emulator’s observability for Tesla battery types. This work involved implementing C++ code to capture and expose DC-DC current and voltage metrics, which were then wired into the system’s MQTT telemetry pipeline. By enhancing the monitoring data available for Tesla battery simulations, the update improved validation, testing fidelity, and real-time fleet monitoring. The approach focused on embedded systems and IoT development, with careful updates to metric paths and documentation, resulting in more accurate and comprehensive data for downstream systems and Tesla battery users.
