Used EV Analyzer

Bring the battery, range, charging, warranty and running costs together before you speak to the seller.

Your vehicle, your numbers

Example numbers are prefilled. Replace them with your vehicle data and local prices. Currency changes the label, not the exchange rate.

Vehicle

Identify the car. Asking price is context, not a valuation.

Where do I find this?

Use the exact model and market in the vehicle documents. A matching name alone does not verify battery specifications.

See the explanation →
Where do I find this?

Use the documented model year, which may differ from the registration year.

See the explanation →
km
Where do I find this?

Read the odometer and verify whether it uses kilometres or miles.

See the explanation →
USD
Where do I find this?

Copy the seller’s asking price. This is context, not an independently verified valuation.

See the explanation →
Where do I find this?

Use the relevant market or document description. Do not enter private identifiers.

Battery evidence

Use figures from the same vehicle and driving conditions.

kWh
Use usable (net) capacity, not gross capacity.
Where do I find this?

Match usable/net capacity to the exact pack and configuration. Check whether this field asks for original or current capacity; gross capacity is different.

See the explanation →
km
Use a 100% range estimate from the same conditions as the consumption figure.
Where do I find this?

Record the full-charge range estimate and the consumption period together. Do not use a new-car advertised range as a current observation.

See the explanation →
kWh/100 km
Use battery-side driving consumption, not energy from your electricity bill.
Where do I find this?

Find recent driving consumption in the vehicle’s trip or energy display. Record the period and units. A charger receipt includes losses.

See the explanation →
%
Optional: transcribe a diagnostic report. EVVerity cannot verify it.
Where do I find this?

Transcribe only a BMS SoH value identified as such in the report. Keep its date, vehicle match and method.

See the explanation →
Where do I find this?

Check the complete report against this vehicle. This checkbox records your confirmation; EVVerity cannot authenticate it.

See the explanation →
%
±10% is an illustrative sensitivity band, not a statistical confidence interval.
Where do I find this?

Choose an input-sensitivity assumption. A larger number widens the scenario; it is not a measured confidence interval.

See the explanation →

Charging & warranty

Optional details from the vehicle documents. Leave unknown values blank.

kW
Enter the correct specification for the variant.
Where do I find this?

Use the limit for the charging type requested here and the exact vehicle configuration.

See the explanation →
kW
Peak rate is not the average charge rate.
Where do I find this?

Find the documented DC peak for this vehicle. A peak is not the average power across a session.

See the explanation →
kW
Where do I find this?

Use the output available from the actual charger and supply, not just the largest number on its label.

See the explanation →
Where do I find this?

Use the start date in the warranty record. Do not assume the date you buy a used car starts a new manufacturer warranty.

See the explanation →
years
From the vehicle-specific warranty document.
Where do I find this?

Enter the duration in the applicable warranty document for this market and vehicle.

See the explanation →
km
Leave blank for unknown or unlimited mileage; this tool cannot confirm cover.
Where do I find this?

Enter the distance limit from the same warranty document and check its units.

See the explanation →

Running costs

Enter your local electricity price and driving distance.

USD/kWh
Where do I find this?

Copy the per-kWh energy price from your bill or charging payment screen. Check whether tax is already included.

See the explanation →
%
Share of grid energy not stored in the battery. This is an editable scenario assumption.
Where do I find this?

Enter the assumed share of grid energy that does not reach the battery. It is a scenario unless supported by measurements.

See the explanation →
km
Where do I find this?

Use your expected distance for a full year, not the car’s lifetime odometer.

Transparent by design

A clearer picture starts here.

Review the example inputs, then calculate. We show the assumptions alongside your result.

Why is this an estimate?

Asking price is context only. EVVerity has no verified market valuation, cannot authenticate seller data, and does not tell you whether to buy a car.

Read our methodology

EVVerity estimates are informational and are not a substitute for a professional battery diagnostic or pre-purchase vehicle inspection.

See how the calculation works

Battery, range, charging and energy-cost formulas are shared with the individual tools. Warranty headroom is calculated only from the dates and limits you enter.

Asking price is context only. EVVerity has no verified market valuation, cannot authenticate seller data, and does not tell you whether to buy a car.

Build a picture from several kinds of evidence

The analyzer organises battery estimates, reported SoH, range context, user-supplied charging specifications, warranty headroom and running costs. Asking price identifies the scenario; it is not compared with a live valuation database and does not generate a purchase verdict.

Where to get useful inputs

  • Collect the original usable baseline and matching range and consumption evidence before estimating capacity.
  • Leave unknown charging limits and warranty details blank rather than guessing.
  • Confirm warranty start, duration and mileage limits with the actual documents. Remaining headroom is not a coverage decision.
Does the analyzer verify the seller’s claims?

No. It keeps their provenance visible, performs the stated arithmetic and highlights questions worth checking. A professional inspection or diagnostic may be needed to resolve them.
