What you need
- Dr. Prius / Dr. Hybrid app
- Bluetooth OBD-II adapter supported by the app
- Vehicle in READY/ON mode
You’ll produce a .csv with Battery block voltages, internal resistance, pack current, SoC, temps, and timestamps — perfect for the analyzer and Gemini review.
One-time setup
- Plug the OBD-II adapter into the car’s OBD port. Turn the car to READY/ON.
- Pair the adapter in your phone’s Bluetooth settings (follow the adapter’s instructions).
- Open Dr. Prius / Dr. Hybrid and connect to your vehicle/adapter.
Record a driving log (CSV)
- In the app, open Battery Monitor (live monitor screen).
- Tap Record (red dot) to start logging.
- Drive for 10–20 minutes with a mix of:
- steady cruise, gentle acceleration
- several regen braking events
- 1–2 stronger accelerations (brief, safe)
- Tap Stop when done, then use Share/Export → CSV to save the log.
Tips for a clean log
- Keep the app foregrounded; prevent phone auto-lock.
- Use a known-good adapter; avoid unstable clones.
- Don’t switch apps while recording.
Safety
- Choose safe roads for accel/regen segments.
- Obey traffic laws; don’t watch the phone while driving.
Suggested driving script
- 2–3 min steady cruise on flat road.
- 3–5 moderate accelerations to ~40–55 mph.
- Several regen events: lift/brake lightly from ~35–45 mph.
- 1–2 strong accelerations (brief).
- 2–3 min town speeds with stop/starts.
Where to find the CSV
Android
- Saved to Downloads or a Dr. Prius app folder.
- Or use the Share menu → Drive/Email.
iOS
- Share → Save to Files (iCloud Drive or On My iPhone).
Import into the Analyzer
- Open this app’s main page.
- Click Choose CSV and select the file you exported.
- Verify the filename shows and the chart renders.
- Optionally click Ask Gemini for an AI summary.
If you previously loaded the Demo, the app clears it and shows your filename automatically.
Troubleshooting
- No CSV recorded? Ensure you tapped Record in Battery Monitor and drove for several minutes.
- Adapter not connecting? Re-pair in Bluetooth settings; power-cycle the adapter and the car (READY/ON).
- Analyzer says “No CSV chosen”? Click Choose CSV again, or load Demo to verify the pipeline.
