Build a battery record from data your Tesla reports.
TSLAIQ is currently in a closed trial.
On supported models, TSLAIQ for iPhone uses a compatible diagnostic adapter to record BMS full pack capacity, fault codes, and available cell group voltages. Each recorded value includes its source and capture time when that information is available. The app sends no commands to the vehicle.
Saved readings can form a dated history over time. TSLAIQ keeps recorded inputs separate from calculated battery health and fitted trend values.
A dated history gives you concrete readings to bring to a service conversation. Tesla makes warranty decisions using its own diagnostics and methodology, and its result may differ from a TSLAIQ calculation.
Available readings depend on the vehicle, adapter, capture conditions, and sync settings. Cell group data appears when the vehicle provides it and the owner opts in to sync it.
