Used EV Check

Why it matters

Why battery health matters more than mileage

Unlike petrol cars, an EV's biggest hidden cost is battery degradation. A well-maintained 80,000-mile EV can have a healthier battery than a poorly-charged 30,000-mile one. Our report gives you the data sellers won't volunteer.

What’s included in your reportIncluded

Battery & range reality

Estimated battery health

A battery bar showing estimated % range retention versus when new, plus a health grade (like A+) where a manufacturer test record exists.

Expected range now

The miles this specific car should realistically do today, and roughly how far below its when-new range that is.

Range performance (WLTP vs real)

The official manufacturer WLTP range shown side by side with the estimated real-world range now: the honest brochure-versus-reality gap.

Remaining battery warranty

How much of the manufacturer battery warranty is left, in both miles and months, with an Active / Expired badge.

Battery & model

Make, model, variant and year, usable and total battery capacity (kWh), and the WLTP range it was rated for when new.

Charging, cost & spec

The data, explained

What each part of the report tells you

Battery health, made visible

The battery is the most expensive part of any used EV, and the one thing an ordinary history check can’t show you. We make it visible. Your report opens with an estimated battery-health reading: a bar showing how much of the car’s original range it’s likely to still hold, drawn from aggregated real-world test data across thousands of electric cars of the same type.

Where a manufacturer battery test record exists for the car, we also show a health grade (a letter grade such as A+) so you can see at a glance whether its condition is normal for its age and model. To be clear about what this is: it’s an estimate and a grade where a record exists, not an OBD-measured State of Health percentage. That honesty is deliberate, and it’s exactly the reading you can’t get from the advert, the V5C or the MOT.

Real-world range now vs when new

Brochure range and the range you actually get are two different numbers. Your report gives you the expected real-world range for this specific car today, factoring in its age and the mileage you enter, and sets it against the official WLTP figure it was sold on. The gap between the two is the honest picture of how the battery has aged.

Because range fades with both time and use, feeding in the real mileage is what turns a generic “this model when new” figure into an estimate for this car, now. Every range figure is an estimate, and real-world results still vary with driving style, weather and terrain. We never promise a guaranteed range.

How much battery warranty is left

Most manufacturers warranty the battery separately from the rest of the car, typically around 8 years or 100,000 miles, and it’s the safety net that covers the priciest component. Your report shows how much of that battery warranty remains, in both miles and months, with a clear Active or Expired badge.

It’s one of the most valuable numbers in a used-EV negotiation: a car with years of battery cover left is a very different proposition from one that’s just run out, even at the same price.

Charging, running cost and the full spec

Where we hold the data, the report is enriched with the practical detail that decides whether a car fits your life: which connectors it takes and how fast it charges, how long a 10-80% rapid charge takes, and whether it supports vehicle-to-load, home or grid.

It also puts real numbers on ownership: running cost in pence per mile across home off-peak, home standard and public rapid charging, real-world efficiency, battery chemistry, and the full spec, performance and Euro NCAP safety picture. These cards appear where EV Database holds that data for the car; if a service is unavailable, that card is simply left out and the rest of the report is unaffected.

The independent history cross-check

Provided by the DVSA

Battery data tells you about the car’s future; its history tells you whether the seller’s story stands up. The report includes the full official MOT history (every test, pass or fail, and any advisories) plus a mileage chart built from the odometer reading recorded at each test.

That timeline is the independent cross-check: it makes clocking and mileage anomalies obvious, and the mileage itself feeds directly into the battery and range estimate above. Two jobs from one trusted, free source.

EV-first, not paperwork-first

How a Used EV Check differs from a standard history check

A standard history check tells you about the car’s paperwork: outstanding finance, write-offs, theft markers, plate changes. Valuable answers, but on an electric car they leave the biggest question untouched: the condition of the battery, the component that can be up to 40% of the car’s value. No history report can tell you whether the pack is at 95% or 70%.

The Used EV Check is deliberately the other way round. It leads with what a history check can’t show (estimated battery health, real-world range now versus when new, remaining battery warranty) and uses official DVSA MOT and mileage records as the independent cross-check. And to be equally clear about what it isn’t: it doesn’t include finance, write-off or stolen-vehicle checks. It’s the EV-specific half of your homework, the half you can do first, straight from the listing.

A standard history check shows

Outstanding finance
Write-off & insurance markers
Theft & stolen-vehicle records
Previous keepers & plate changes

The paperwork answers, but nothing about the battery.

The Used EV Check shows

Estimated battery health & grade
Real-world range now vs when new
Remaining battery warranty
Charging & running cost (where available)
Full MOT & mileage history

The EV-specific answers no history report can give.

The pre-purchase checklist

What to check when buying a used electric car

Buying a used EV isn’t riskier than buying a petrol car, just different. The engine and gearbox worries disappear; in their place comes one big question about the battery and a handful of practical ones about charging. Here’s the checklist, and where the report answers each item.

1
Battery health first
Get an estimated battery-health reading before anything else. It’s the single biggest factor in what the car is worth. In the report: the battery bar and health grade.
2
Remaining battery warranty
Most manufacturers cover the pack for around 8 years or 100,000 miles. A car with years of battery cover left is a different proposition from one that’s just run out. In the report: warranty remaining in miles and months.
3
Real-world range, not the brochure
Judge the car on what it should actually do today, not the WLTP figure it was sold on. In the report: expected range now, side by side with the official number.
4
Charging that fits your life
Check the connectors, maximum charge speed and 10-80% rapid time against how you’ll really run the car: home overnight, public rapid, or both. In the report: charging compatibility and fast-charge figures, where available.
5
The MOT and mileage story
Cross-check the seller’s story against official DVSA records and look for mileage anomalies; the mileage also feeds the range estimate itself. In the report: full MOT history and the mileage chart.
6
Then, and only then, go and view
Save the trip for a car whose numbers already stack up. In person, check the cables and V5C, take a proper test drive, and consider a plugged-in battery test for final confirmation on an older car.

This homework pays for itself: UK market research suggests buyers pay several hundred pounds more for a used EV with evidenced battery health, and that such cars sell noticeably faster. £9.99 and thirty seconds to know the numbers before you travel is the cheapest part of the whole purchase.

FAQs

Used EV Check questions

What does the Used EV Check actually include?

Estimated battery health and real-world range now versus when new, an estimated degradation figure, remaining battery warranty and battery capacity, plus charging, running cost, efficiency, spec and safety, and full MOT and mileage history. The charging, cost and spec cards appear where EV Database holds that data for the car.

Do I need the car’s VIN?

No. Just the UK number plate and the current mileage. We look everything else up from the registration, and pre-fill the mileage from the latest MOT so you only confirm it.

Is the battery health a measured State of Health?

No. We show an estimated range-retention figure and a battery-health grade where a manufacturer test record exists, not an OBD-measured State of Health percentage. A measured SoH needs a physical test with the car plugged in.

Which vehicles can I check?

Electric cars and vans we hold data for. We confirm the vehicle is eligible before you pay, so you’re never charged for a vehicle we can’t check.

Are the range figures guaranteed?

No. Every range figure is an estimate based on aggregated test data, and real-world results vary with driving style, weather and terrain. We never promise a guaranteed range.

What if you can’t generate my report?

If the battery and range data isn’t available for your car, we don’t produce a report and you’re refunded in full, automatically.

Does the Used EV Check include finance, theft or write-off checks?

No. It deliberately focuses on what a standard history check can’t show: estimated battery health, real-world range, remaining battery warranty, charging and running costs, backed by official MOT and mileage history. For provenance questions like outstanding finance or write-offs, pair it with a standard vehicle history check.

Can I check a car before viewing it?

Yes, that’s the point. The check needs only the registration and mileage, both usually shown in the advert, so you can screen a car straight from the listing before contacting the seller or travelling to a viewing.

Which brands are covered, and does it work on Teslas?

Coverage spans the mainstream UK electric car market: Tesla, Nissan, Kia, Hyundai, Volkswagen, BMW, MG, Jaguar and many more. We confirm the exact car is one we hold data for before you pay, so you’re never charged for a car we can’t check.

Is it worth paying to check a used EV’s battery?

The battery can be up to 40% of the car’s value and £5,000-£15,000+ to replace, and a seller has no obligation to evidence its condition. Against that, £9.99 to see its estimated health, range and remaining warranty before you commit is the cheapest part of the whole purchase.

How long does the check take?

Seconds. Enter the reg and mileage, pay, and the report appears on screen immediately, with a downloadable PDF and an email copy sent at the same time.
