Sell EVs with confidence using verified battery health certificates.
Navionyx helps EV dealers, fleet operators, leasing companies and resale platforms verify battery condition using plug-and-play diagnostics, guided test drives, and QR-verifiable digital certificates.
The biggest question in used EV resale: how healthy is the battery?
The battery is the most expensive and most important component of an EV. But buyers can't easily verify its true condition. Dashboard range isn't enough. Seller claims aren't enough. A verified certificate builds trust.
- Used EV buyers hesitate because battery condition is unclear.
- Dealers lose value during negotiation without proof.
- Fleet owners can't prove battery quality during resale.
- Finance and insurance teams need reliable battery data.
- Different EVs report battery health inconsistently.
Navionyx Battery Intelligence Report
A structured battery health test using real vehicle data. Our plug-and-play diagnostic device reads BMS, voltage, current, temperature, SOC and fault-code data — combining multiple signals into a practical, QR-verifiable certificate.
The Navionyx certification process
Six guided steps from device-plug to verified certificate. Designed for technicians, built for trust.
Connect the diagnostic device
The partner connects the Navionyx plug-and-play device to the EV. It begins collecting BMS, voltage, current, SOC, temperature and vehicle data.
Charge the EV to 100%
A clean starting point. Full charge improves the quality of capacity and range estimation across the test.
Start the test from the Navionyx app
The dashboard verifies vehicle details, SOC, odometer, BMS status and live data availability before the test begins.
Perform a guided test drive
Drive 15–25 km along a guided route — city driving, steady speed, controlled acceleration, regen check and a short idle recovery. Performed safely, only where road conditions permit.
Analyze battery behavior
SOH, usable capacity, voltage sag, current response, cell balance, thermal behavior, BMS faults, regen response and estimated real-world range — all combined into a single rating.
Generate the verified certificate
A digital certificate is issued — certificate ID, QR code, battery score, vehicle details, test summary and digital signature. Shareable instantly.
Eight signals into one battery health score
A single SOH number isn't enough. We combine BMS data, electrical behavior, thermal stability and drive-cycle response.
State of Health
Estimated battery condition compared to expected original capacity.
Usable Capacity
Approximate remaining usable energy available in the pack.
Voltage Response
Voltage drop behavior under acceleration and load conditions.
Cell Balance
Difference between minimum and maximum cell voltages.
Thermal Stability
Battery temperature behavior tracked through the test drive.
BMS Diagnostics
Fault codes, warning codes and sensor status from the BMS.
Regen Response
Battery response during deceleration and energy recovery.
Estimated Range
Practical real-world range based on observed energy use.
A certificate buyers can trust
Hover any hotspot to explore. Every section is designed for clarity, transparency and verification.
Every certificate comes with QR verification
Scan the QR on any certificate. Buyers see the report instantly. No login required.
One scan, full transparency
Each certificate has a unique QR linked to a verification page with all key details.
Privacy-first by design
Sensitive fields like full VIN, owner mobile and registration are masked publicly unless required.
Tamper-evident
Digital signatures and certificate IDs make every report independently verifiable.
Always up to date
Status reflects valid, expired or revoked in real time — buyers always see the truth.
