How it works

Three steps.
Full picture.

No technical knowledge required. If you can plug in a USB stick and pair a Bluetooth device, you can inspect any EV.

01
Plug In

Plug the BlackBox into your EV's OBD port — it's under the dashboard, same port a mechanic uses. Takes 5 seconds.

02
Connect

Open the inspectEV app on your phone. It finds the BlackBox automatically via Bluetooth. Select your car model and tap Connect.

03
Inspect

In minutes you have a full battery health report — SOH%, cell voltages, battery verdict, and a PDF you can share or save.

None at all. If you can plug a USB stick in and connect a Bluetooth speaker, you can use inspectEV. The app guides you through every step. The whole process takes under 2 minutes.
State of Health is the percentage of original battery capacity that remains. A brand new EV has 100% SOH. After years of use it degrades — 90% SOH means 10% of original range is gone permanently. Knowing the SOH is the most important number when buying a used EV.
We ship the BlackBox kit to you. You pay the courier when it arrives at your door — cash or card depending on your country. No online payment, no card details needed upfront.
inspectEV reads data directly from the battery management system — the same computer your car uses to manage the battery every second. Depending on the method available for your car, accuracy is typically ±0.5%. This is the same data professional tools use in official authorized dealerships, without the dealership price tag.
