True battery health and tamper-proof mileage — in 60 seconds See demo report
A used Tesla's price hangs on battery health and real mileage — and both are invisible on a test drive. Dashboards can be rolled back. A tired pack looks perfect until winter. TSLASCAN reads the numbers the car keeps to itself.
Mileage is edited on the used market every day. A single dashboard number is trivial to fake — and impossible to challenge without the car's own records.
Two identical cars can be 8% or 20% worn. That gap is thousands in range and resale — and it never shows on a short drive.
A replaced or flood-salvaged pack carries a different history than the chassis. Without pack identity and calendar age, you'd never know.
Everything below comes from the battery's own broadcast data — measured, not estimated.
SOH from the pack's own factory Beginning-of-Life energy, read per car — not a generic lookup table. The real capacity left, in kWh.
Cross-checks up to three independent mileage sources (gateway, BMS, dashboard). A rollback has to fake every one of them to pass.
All 96+ bricks rendered in 3D. A weak or imbalanced cell stands out instantly — height is voltage, colour is sag under load.
Internal resistance (DCIR) and per-cell voltage sag measured while driving — the health signals a seller can't hide at rest.
HV insulation resistance and stored BMS fault codes — early warning of moisture, wear, or a pack that's been through something.
Every report lives on tslascan.com with a unique ID and a live device check. Screenshots can be edited; the live page can't.
Motor torque and power on every driven axle — AWD or RWD confirmed — plus battery and powertrain coolant temperatures. The drivetrain's health, read live.
Every scan is kept per car: SOH over time, cell balance at each charge level, and whether a weak cell is getting worse — a picture a live-only scanner can't give.
All 96 cells charted in real time, with an optional one-tap raw log recorder that captures every scan for deep offline analysis.
Connect the analyzer to the car's diagnostic port. It's listen-only — it reads the bus and never writes a single command to the car.
A minute parked captures cell balance; a short drive captures resistance and sag under load. Data streams to your report, encrypted end-to-end.
Scan the QR on the device — or open the link — for a clear BUY / CAUTION verdict you can hand straight to the buyer.
One analyzer, the whole range — from the first Model S to the latest Cybertruck.
No jargon dump. A used-car buyer sees a green BUY or an amber CAUTION, the SOH, the mileage cross-check, and the 3D cell map. A live link on our domain proves it wasn't Photoshopped.
Every plan is the same analyzer and the same full report — plans differ only in how many cars you can connect per month.
Sell faster with proof, or buy with confidence. One analyzer does both.
