A. CAN bus capture: 1. Connect USB-CAN adapter to vehicle BMS connector 2. Run capture scripts on live vehicle 3. Confirm correct CAN H/L pin pair using oscilloscope/multimeter B. Protocol reverse engineering: 1. Analyze raw CAN frames using CAN analysis software 2. Identify BMS message IDs, SOC byte, cell voltage, and temperature encoding 3. Document frame structure and timing patterns C. BMS emulator development: 1. Write Arduino firmware to replay captured BMS frames 2. Test emulator output against vehicle MCU expectations 3. Iterate until vehicle accepts emulator as native BMS D. Multi-vehicle expansion: 1. Repeat capture and analysis on second vehicle platform 2. Compare protocol differences across platforms 3. Build reusable emulator framework for multiple vehicle types E. Documentation: 1. Maintain a signal map spreadsheet (CAN ID - signal - scaling) 2. Log every session: what was tested, what worked, what didn't
