BattGrade: EV Battery Check

BattGrade reads the high-voltage battery of an electric car and shows its state of health (SoH) in a few minutes. How it works: • Plug a Bluetooth OBD2 adapter into the car's diagnostic port. The app tells you which adapter and cable each model needs, and where the port is. • Switch the car on, connect the app to the adapter and start the reading. The app identifies the car from its VIN. • You see the state of health with a letter grade, the method behind it and its margin, plus the values read from the battery: cell voltages, temperatures, energy counters and more. What you should know: • Results are for information only. BattGrade does not issue certificates at the moment. • Testing is free. • The list of supported models is in the app and on battgrade.com. When the data cannot give a score, the app tells you plainly and our team looks at the case. • The app only sends read-only diagnostic requests. It never writes to the car, clears fault codes or changes settings. • Accounts are reviewed before activation. After you sign up, we check your request and email you when your account is active. Available in 12 languages: English, French, German, Italian, Spanish, Portuguese, Polish, Romanian, Dutch, Swedish, Norwegian and Finnish. BattGrade is a brand administered and managed by TOPFED WEB S.R.L., a company registered in the Republic of Moldova.
