⚡️High-voltage battery diagnostics for electric vehicles

One of the most important factors in an electric vehicle’s value is the condition of its high-voltage (HV) battery. Based on data read directly from the vehicle, our diagnostics provide an objective picture of the battery’s measurable condition, including the manufacturer-calculated SoH (State of Health) value.

Security for used-car buyers.
Trust for sellers and dealers.

We can diagnose most models from Tesla, Volkswagen, Audi, Skoda, Cupra, BMW, KIA, Hyundai, Nissan and BYD.

This is not manufacturer marketing data, and it is not issued by the dealer.

It is an independent, verified and easy-to-share certificate that clearly shows the real condition of an electric vehicle battery.

  • Want to buy an electric vehicle with confidence?
  • Want to sell your electric vehicle faster or at a better price?
  • Want to make your sales process more credible as a dealer?

AkkuCheck diagnostics add confidence to buying and selling electric vehicles, for private sellers and dealers alike.

Proprietary battery diagnostic technology

AkkuCheck diagnostics use our own software and partially proprietary hardware. The system is developed in Hungary, with Hungarian infrastructure and support.

We connect to the vehicle through the OBD port using a laptop and only read data. The process is completely safe and usually takes 10-15 minutes.
