Range
The gap your buyers complain about.
Official range figures assume a brand-new battery. Winter, the motorway and 100,000 km tell a different story. SuperElectric puts the honest number on the listing, so buyers see it before they buy, not after.
572→249 km
The same car at 120 km/h, after 100,000 km.
Both SuperElectric figures are accurate to ±3%, and adjusted for this car's battery health today, not a new pack.
Battery health
Even a certificate needs context.
A battery certificate is only half the answer. Is 95% good for this car? Buyers have no way to tell. SuperElectric predicts the whole range a healthy pack should land in, for that exact make, model, age and mileage. No inspection, no hardware. A strong battery finally has something to prove itself against.
92.9%expected
The healthy reading for this exact car, predicted from its age and mileage alone.
SuperElectric expects this car's battery health to follow a bell curve centred on 92.9 percent, with 9 in 10 comparable cars falling between 88.2 and 97.6 percent. This car's certificate reads 95 percent, above the median and well inside that range.
This car's certificate reads 95%, above the median for its age and mileage. Your listing can say so.
9 in 10 cars of this model, age and mileage land between 88.2% and 97.6%. This one is performing better than most of them.
One API becomes a listing feature.
Most used-EV listings can't answer the only questions an EV buyer has, so buyers hesitate, enquiries go elsewhere and EVs sit longer than they should. The API closes that gap: send an EV and the conditions, render the answers in your listing template. No fleet hardware, no OBD dongles, no data science team.

Three products you could ship next quarter.
SuperElectric data is the ingredient. These are the products marketplace teams build with it, and charge for. And with EU battery passports arriving in 2027, platforms that show battery data now set the standard the rest will chase.
New seller revenue
Premium EV listing tier
Listings with verified range and battery data become an upgrade sellers pay for.
Faster used-EV intake
Trade-in confidence report
Instant, defensible EV valuations your sellers can put in front of a customer.
Engagement & SEO
Buyer-facing range checker
Shoppers test any EV against their winter commute, right on your domain instead of a forum.
A 15-minute walkthrough, with data from your market.
Six answers. One API.
1 · Range
One official figure can't answer the two questions every buyer has: the winter commute and the motorway holiday. Real-world range does, at every speed and temperature that matters.
You get
- Real-world range across 100+ speed and temperature combinations
- The WLTP figure alongside, so the listing shows an honest gap
- Combined with battery health, a range figure for this exact car
2 · Battery health
The pack is a used EV's biggest unknown, and workshop tests don't scale to an inventory. SuperElectric predicts every battery's condition from data alone, so buyers stop treating used EVs as a gamble.
You get
- Predicted state of health from age and mileage, no workshop visit
- A calibrated 90% confidence band that flags certificates below it
- Degradation forecasts up to 11 years ahead, for pricing and finance
3 · Routes
Range anxiety is really route anxiety: will this car handle the Friday drive to the mountains? Route simulations answer with the whole trip, so buyers arrive at the enquiry already convinced.
You get
- Total drive time, charging stops and the duration of every stop
- Summer and winter versions of each route
- Any route prepared for your market, on request

4 · Charging
Charging is the part of EV ownership first-time buyers fear most, and oversold speeds come back as complaints. Honest estimates before the sale mean fewer tickets after it.
You get
- Charging times for six everyday scenarios, from a 2.3 kW socket to 350 kW fast charging
- 10-80% and full-charge durations, with charging losses included
- Scenarios a car cannot support are omitted, never glossed over
5 · Residual value
What an EV will be worth is the question that stalls purchases, and generic pricing models miss what batteries do to value. SuperElectric forecasts value from EV evidence, so sellers get a number they can defend and finance partners can price risk on.
You get
- Value forecasts up to five years ahead, with a prediction range
- Built on battery health, real range, warranty position and model demand
- Activated for your market on request
Price outlook
EV-adjusted value forecast
Estimate uses EV-specific battery, range, charging, warranty and demand signals.
Ownership cost outlook
EV versus familiar combustion alternative
Assumes a 15,000 km/year European usage profile and energy plus service running costs.
6 · Running costs
What a car actually costs to run is every first-time EV buyer's question, and almost no listing answers it. The ownership comparison gives the EV an edge a spec sheet never shows.
You get
- Cost per km in winter and summer, at city, road and motorway speeds
- Local electricity prices for your market
- A five-year comparison with a combustion car, both sides from our data

What teams ask before getting started.
Yes, we cover the European market with 1,000+ EV models. Our data includes all major manufacturers and is updated quarterly with new models.
Our range predictions are accurate within 3% of real-world results across varying speeds and temperatures, and battery health predictions within 5%, validated against real-world data from thousands of vehicles. Every range figure is also adjusted for the battery degradation of that specific car, unlike WLTP, which assumes a brand-new battery and can miss by up to 50%.
One REST call per listing, returning JSON you render in your existing template. Most teams have a first EV listing showing live data within days, not months.
Pricing depends on your market and listing volume. See the pricing page for tiers, or book a demo for a quote.
We update our data at least quarterly to include new EV models and the latest real-world test results.
All SuperElectric servers are hosted in the European Union. Each client receives a dedicated server instance, with no shared infrastructure. We guarantee 99.5% uptime via SLA, and your data never leaves EU jurisdiction.
