Telemetry
Fleet Telemetry streaming
Receive selected HV health signals directly from the vehicle to your server — efficient, change-based, no polling drain.
Independent vehicle health platform
Professional EV health diagnostics
Advanced Fleet Telemetry analysis for HV battery, BMS, drive inverters, charging health and service alerts. Built for Tesla vehicles via official Fleet API — without location or trip tracking.

Interactive demos in the browser — no account required. Same flow you’ll use in the personal cabinet.
Live health board
Real-time style signal board: BMS, inverters, charging and alerts with multi-select charts.
Open live demo →Battery health
SOH, brick imbalance, thermal spread and isolation overview for pack wear insight.
Open battery health →Fault history replay
Pick year, day and time range, then scrub signals around Service / ServiceFix alerts.
Open history →Why choose EV Diag Tool?
Built like a workshop platform — for owners and technicians who care about health and wear, not location analytics.
Battery
BMS & cell health
Pack voltage/current, brick balance, module temperatures, isolation resistance, HVIL and energy trends for degradation insight.
Drivetrain
Inverter & motor stress
Drive inverter states, currents, torque, stator and heatsink temperatures to catch thermal and fault patterns early.
Incidents
Fault history replay
Pick year, day and time range, then scrub the signal window around Service / ServiceFix alerts for workshop review.
Cabinet
Personal workspace
Account cabinet for vehicles, health reports and archives — same clear login / register flow you expect from a diagnostics platform.
Privacy
No location tracking
We deliberately exclude Location, GPS, routes and trip maps. Context fields like odometer and speed support wear analysis only.
Monitoring coverage
A focused signal set for predictive HV diagnostics — explored live in the demo.

Authorize the app and add the virtual key in Tesla: tesla.com/_ak/evdiagtool.com
Step 03
Get results
Stream Fleet Telemetry, review health trends, and export fault windows by date and time.
What we do not collect
Unlike trip trackers, EV Diag Tool is scoped to vehicle health.
- no Location, GPS state, GPS heading
- no Origin / destination / route line
- no Trip maps, geofences, movement history
- no Cabin climate and multimedia signals
