Diagnostic certification of traction batteries
We use some of the industry’s most reliable certification technologies for electric and plug-in hybrid vehicle batteries. We provide the final, independent verification of the traction battery’s condition and safety.
We are the first mobile traction battery diagnosticians in Poland — we come to you with a certified measurement, with no queues and without leaving your car for several days.
Real condition, not guesswork
An objective reading of 50+ parameters straight from the BMS — instead of estimates and the seller’s word.
Safety and peace of mind
Early detection of degradation, cell imbalance and thermal risk before they become a costly problem.
Resale confidence
A Voltified certificate raises the resale value of an electric vehicle by providing verified data on the battery’s condition.
A stronger negotiating position
An independent certificate is hard evidence for buying, selling, leasing and insurance — credible to both sides.
A certified measurement in ~3 minutes, with no disassembly
As the first mobile EV battery diagnosticians in Poland, we bring the examination to you. Our diagnostician connects directly to the vehicle's BMS bus and captures a full picture of the traction battery's condition — non-invasively, without opening the pack. We analyse more than 50 parameters: SoH, cell balance and voltages, internal resistance, the thermal profile and the charging history. On this basis we issue an independent certificate confirming the actual condition and safety of the traction battery.
What you receive
- “Złoty Standard” certificate — an independent PDF document with a number and a QR code for online verification.
- A 50+ parameter report — a full read-out from the BMS together with an interpretation of the results.
- Interpretation and assessment of the result together with Voltified recommendations — suitability for further use, leasing, sale or second life.
- A visit from a mobile diagnostician — your result the same day.
