EV Diag Tool

Vehicle health, not driver tracking.

Independent predictive diagnostics for Tesla high-voltage systems: BMS, cell balance, isolation, drive inverters, charging health, and service alerts — so you can spot wear early and reconstruct what happened around a fault.

Monitoring framework

Full Fleet Telemetry set for HV health and wear. Location and route fields are excluded by design.

How the data is used

Three jobs only — predict, explain, service.

Predict wear

Trends in brick imbalance, pack energy, module and inverter temperatures before a roadside failure.

Explain a fault

Window of BMS / inverter / charge signals around VehicleAlerts and VehicleErrors for workshop review.

Charge & isolation

AC/DC charge anomalies, cable/phase issues, HVIL and isolation resistance for HV safety health.

What we deliberately do not collect

This product is not a trip tracker. Customer movement history is out of scope.
