Some questions come up again and again. If you're unable to find your question, we will be happy to assist you personally:

The manufacturer-independent, objective AVILOO PREMIUM Test is available for both fully electric vehicles and plug-in hybrid vehicles.

You can check whether your vehicle is approved for the AVILOO PREMIUM Test in our database:

🔗 Vehicle coverage

We are constantly expanding the list and regularly adding new models.

The AVILOO PREMIUM Test was developed for end customers. It records a complete charging cycle of the traction battery, providing a particularly accurate and comprehensive assessment. The FLASH Test is designed for other areas of application.

In some cases, the vehicle data collected is checked manually by our technical team. This additional quality control may cause delays, but our team will do its best to deliver your certificate as quickly as possible.

The QR code on the printed AVILOO Battery Certificate leads directly to the original digital version on the AVILOO website. By comparing the digital and printed data, the authenticity of the certificate can be clearly verified.

The State of Health (SoH) read by the battery management system (BMS) is based on manufacturer-specific algorithms and can differ significantly from the actual state of the battery – sometimes being too high or too low. The AVILOO Certificate, on the other hand, provides an independent, objective assessment of the battery state based on a comprehensive technical analysis. Not only is the actual SoH determined, but the battery is also checked for possible defects and anomalies. This provides a comprehensive picture of the functionality and safety of high-voltage batteries.

The AVILOO Box is specially configured for one-time use. It remains the property of AVILOO GmbH and must be returned within 4 weeks of receiving the certificate.

A return label is included in the package. You can use this to return the box easily and free of charge at a post office.

Yes, the independent AVILOO PREMIUM Certificate can be used as objective proof of the condition of the battery in legal disputes.

We are working hard to roll out the AVILOO PREMIUM Test internationally. If your country is not currently supported, please contact us at:

The Early Access Test allows you to test a vehicle before its official release with the PREMIUM Test – ideal for models that are still in the final testing phase.

The AVILOO PREMIUM Certificate displays the so-called State of Health (SoH) – i.e. the health status of your battery – as a percentage. In addition, a realistic range is derived from this. All values are displayed transparently, clearly and in an easy-to-understand manner.
