Free Tesla VIN Decoder — What You Can Learn
This tool decodes any 17-character Tesla Vehicle Identification Number (VIN) and explains every digit: manufacturer, model, model year, assembly plant, motor/drive type, and serial number.
The decoder estimates whether your car has an LFP (lithium iron phosphate) or NCA/NMC (nickel) battery — critical when buying a used Tesla Model 3 or Model Y. Optional mileage input helps estimate charge cycles and battery State of Health (SOH).
Beyond decoding, the built-in Tesla battery calculator estimates usable capacity in kWh, State of Health (SOH), real-world remaining range, charge cycle count and yearly degradation — so you can check a used Tesla's battery health before you buy and avoid surprises with range loss.
What the Tesla battery calculator can do
- Decode the full 17-character Tesla VIN: manufacturer code, model, body, battery code, motor and drive type, check digit, model year and assembly plant.
- Detect battery chemistry — LFP (LiFePO4) vs NCA/NMC (nickel) — and the likely cell supplier: CATL, BYD Blade, Panasonic 2170 or Tesla 4680.
- Estimate factory usable capacity (kWh) for each pack, with a manual override for a precise battery capacity calculation.
- Calculate battery State of Health (SOH), degradation percentage, remaining kWh and remaining EPA range in km or miles.
- Estimate production date, battery age, mileage and charge cycles, including Supercharger / DC fast-charging stress and vampire (idle) drain.
- Forecast future battery degradation and show warranty status (years and km/miles) for every Tesla pack.
Supported vehicles and data sources:
- Model 3, Model Y, Model S, Model X, Cybertruck, and Tesla Semi VIN patterns
- Battery chemistry detection: LFP (CATL/BYD) vs NCA Panasonic 2170 vs Long Range packs
- Factory codes: Fremont, Austin, Shanghai (Giga 3), Berlin (Giga 4), and more
- Based on NHTSA Part 565, TeslaTap, Tesla Service documentation, and EV-Database
- Interactive decode — enter a VIN above for instant results (requires JavaScript)
Who uses this Tesla VIN & battery tool
- Used Tesla buyers checking battery health, range and degradation before purchase
- Owners verifying model year, factory and battery pack type straight from the VIN
- Dealers and appraisers estimating resale value and remaining battery life
- EV enthusiasts comparing LFP and NCA batteries across Model 3, Y, S, X and Cybertruck
Frequently asked questions
How do I know if my Tesla has an LFP or NCA battery?
Enter your VIN above. The decoder reads the battery code and factory to determine whether you have an LFP or NCA/NMC pack.
How is Tesla battery State of Health (SOH) calculated?
The calculator combines calendar aging, mileage, charge cycles, DC fast-charging stress and idle drain to estimate SOH, remaining kWh and remaining range.
Is this Tesla VIN decoder free?
Yes. The Tesla VIN decoder and battery capacity calculator are completely free and run in your browser.
Which Tesla models are supported?
Model 3, Model Y, Model S, Model X, Cybertruck and Tesla Semi from the Fremont, Austin, Shanghai and Berlin factories.
