Independent EV inspection · Budapest · Surroundings of Budapest
Don’t buy a used EV on trust alone.
On-site battery and condition inspection in Budapest and the surrounding area. A signed report anyone can verify, in your hands before you leave the car.
The sample report contains fictitious demo data; its verification page works exactly like a real one.

01 / The problem
The figure on the dashboard is not an independent measurement.
The car’s own controller estimates the battery’s condition, and that estimate can be reset. In a used EV the battery is the single largest unknown in the price — and it is usually the one thing you cannot check on the spot, while you are deciding.
02 / What we inspect
Only what we actually measure and read
Each item states its scope and limits. Where something cannot be assessed, the report says so.
Battery: AVILOO FLASH test
An independent estimate of the traction battery’s state of health, calculated by AVILOO from data read during a short test. You get the original AVILOO certificate; the report records its number and fingerprint.
An estimate, not a full capacity (discharge) test. Included in both packages.
Battery: data reported by the car
On supported models we read, strictly read-only, what the car’s own battery management reports – cell voltages, temperatures and its own state-of-health figure. The report labels these as values reported by the vehicle.
Not an independent measurement. Currently the Dacia Spring (pilot). Full condition report only.
Fault codes and control units
A read-only readout of stored fault codes with their status, and a list of every control unit that did not answer. Nothing is cleared, coded or actuated.
Currently the Dacia Spring (pilot). Battery health is never derived from fault codes. Full condition report only.
Bodywork: paint thickness
Paint-thickness readings on every metal panel, shown on a drawing of the car’s own model, to reveal repainted or filled areas.
Indicative sampling; plastic and glass parts cannot be measured. Full condition report only.
Tyres
Inner, centre and outer tread depth on all four tyres, against the legal minimum and the recommended replacement threshold.
Full condition report only.
Climate control
Cooling and heating checked at the vents with infrared surface readings, with the conditions recorded.
A screening check, not a refrigerant or system diagnosis. Full condition report only.
The signed report
Every value with its source and every limitation stated, frozen and digitally signed at the end of the inspection, and verifiable by anyone through its QR code.
Full condition report only. The battery test alone comes with the AVILOO certificate.
Every report is cryptographically signed. Anyone can scan the QR code and confirm the document has not changed since it was issued — without involving us.
Raw measurement data is retained as evidence.
The report states what could not be assessed. We do not certify anything we did not measure.

For buyers
You’re about to buy
The seller is pressing, and the decision is today. The inspection happens at the car, and when it ends the finished report is on your phone. Not a promise of a report — the document itself, on the spot.
A QR code in the listing sets your car apart. The buyer verifies rather than trusts, which shortens negotiation and reduces disputes after the sale. For several vehicles we quote individually.
Electrical engineer and technical informatics engineer
Electric vehicles and software systems are both long-standing interests of mine, and BATTOCAN is where the two meet. I understand the vehicle-side electronics and diagnostics first-hand, and the measurement and reporting system around them is built in-house rather than bought in – which is why every value in a report can be traced back to how it was obtained.

Prices are final; no VAT applies. The service is invoiced by a sole trader under the Hungarian small-business VAT exemption, so no VAT is charged and none can be deducted.
For HUF 12,000 more than the battery test alone, you receive the complete signed, independently verifiable report rather than a single figure.
The AVILOO FLASH test is a state-of-health estimate, not a full capacity test. No package guarantees a clean result: the report states what could not be assessed.
How is this different from the percentage shown on the dashboard?
The dashboard figure comes from the car’s own battery management, and it can be reset or recalibrated. The AVILOO FLASH test is an independent estimate made with AVILOO’s method, and the report names its source. Where we also read the car’s own figures (supported models), the report shows them separately and labels them as reported by the vehicle – never as a measurement.
Can the report be faked or edited afterwards?
When the inspection is closed, the report data and the PDF receive a SHA-256 fingerprint and are signed with our Ed25519 key. The verification page recalculates the fingerprint and checks the signature, and anyone can also check it without us, using the published public key. A correction is only possible as a new, numbered revision; the earlier revision stays on record.
What happens if a control unit cannot be reached?
The report lists every control unit that did not answer and states that its condition could not be assessed. An unreachable control unit is never counted as fault-free, and a partial readout is never presented as a clean result.
What if the battery turns out to be fine – was the inspection wasted?
No. A good report is a negotiating position you can show, and for the price of the inspection you avoided a decision worth millions of forints taken blind. It also documents the car’s condition on that day.
Does the report guarantee the car won’t develop a fault later?
No. The report records what was measured and read on the day of the inspection, within the stated scope. Batteries and components can fail later for reasons no inspection can foresee, and some systems cannot be assessed on site. The report is not a warranty and not an official roadworthiness test.
Who performs the inspection and who issues the invoice?
The listed services are sold and invoiced by Gulyás Adrián e.v.. The inspection is performed by Gulyás Adrián e.v.. Codelit 40 Production Management Zrt. operates BATTOCAN: it developed the method and the reporting system, and it signs and publishes the report. That is why the invoice shows a different name from the report’s issuer.
How long does the verification page stay available?
The verification page stays available for 24 months after the report is issued. If the page is withdrawn earlier, it says so and when. A PDF you downloaded remains your copy, but online verification needs the page.
