The new independent AVILOO Battery Certificate

Benchmarking, transparency, and assurance

Clarity for buyers. Trust for sellers

The new independent AVILOO Battery Certificate is the most innovative independent battery analysis for buyers and sellers of used electric vehicles (EVs) and plug-in hybrid vehicles (PHEVs). It provides a clear, data-based assessment of the battery state, enabling buyers and sellers to make informed decisions.

The independent full analysis

The certificate confirms the state of health (SoH) of the traction battery and ensures that it meets safe operating standards.

The SoH value is calculated using the AVILOO algorithm based on real vehicle data.

The report includes a comparative analysis with similar electric vehicles, allowing buyers to evaluate battery performance within the vehicle class.

A visual scale clearly indicates whether the vehicle's battery is performing below average, average, or above average.

The test checks the functionality of the battery management system, sensor accuracy, important parameters at pack and cell level, and communication stability.

The voltages of the entire battery pack and individual cells are analyzed to rule out hidden defects.

The report identifies anomalies or potential risks, avoiding costly surprises after purchase.

In addition to the WLTP range, we also provide a real-world range based on comparable vehicles and an individual range based on the vehicle's previous average consumption.

The AVILOO FLASH Test is quick (3 minutes), easy to perform, and completely independent – the official certificate is issued immediately.

The results are securely stored and can be accessed at any time via QR code, allowing buyers and sellers to verify authenticity directly.

What does the PREVIEW show?

The PREVIEW ensures visibility and trust:

 

  • Confirms the technical inspection of the traction battery

  • Shows the battery's state of health (SoH)

  • Visualizes the SoH in comparison to comparable vehicles

  • Verifies central battery function

AVILOO CERTIFIED

The “AVILOO Certified” seal confirms that the traction battery of an electric or hybrid vehicle has been tested in accordance with the AVILOO FLASH or PREMIUM Test procedures and meets the necessary criteria for safe operation.

The SoH value was determined using the AVILOO FLASH or PREMIUM Test and is within a safe range for vehicle operation.

The calculation is based on data provided by the vehicle, which is evaluated by AVILOO algorithms using statistical and analytical models.

Deviations in the SoH value can be caused by faulty or manipulated data in the control units.

The battery management system is functioning properly.

The battery sensors are functioning properly.

The battery readings are within the normal range.

The voltages of the battery cells are stable.

Vehicle communication runs smoothly.

In at least 95% of reference measurements, the maximum possible deviation of the SoH value does not exceed ±3%.

The test result only describes the state of the battery at the time of testing and is not a prediction of its future performance.

The calculation is based exclusively on data provided by the vehicle, which is evaluated by AVILOO algorithms using statistical and analytical models.

Defects or faults for which the vehicle does not provide any data via the diagnostic interface – such as mechanical damage or external influences – cannot be detected and are not included in the diagnosis.

The AVILOO Certified seal provides transparency and certainty regarding the state of the battery – independently and reliably in the used car market.

So far, we have only had positive experiences with our colleagues at AVILOO. Communication is always fast, professional, and very friendly.

The device/system is also running to our satisfaction. Apart from one tiny error after a software update, we have not had any problems with the devices. AVILOO responded very quickly to the error and solved the problem within a few minutes.

Unfortunately, some models still lack the data required to read the batteries. However, this only affects very new vehicles, and I am sure that AVILOO is working hard to enable battery testing for these vehicles as soon as possible.

We look forward to continuing our excellent cooperation.

Do you have any
questions?

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:

📧 help@aviloo.com

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.
