We work exclusively with AVILOO to check battery performance/charge status and are very satisfied with the results. The FLASH Test also allows us to obtain results within a few minutes as part of a purchase inspection. We print out the certificates and include them in our used car file so that we can present the condition of the vehicle to the customer at any time.

I have to be honest: I don't know of any other device that works so easily, intuitively, and thoughtfully. The battery test is quick and straightforward – and before I'm even back at my desk, the certificate is already on my computer. The integrated SIM card is a real game changer: no plugging in, no problems with data transfer. No matter how quickly you get back to the office, the result is already there. I'm impressed!

The AVILOO FLASH test provides us with a quick and reliable assessment of the battery state in just two minutes. By analyzing a complete discharge cycle, we obtain an extremely accurate and detailed evaluation that provides valuable information for us, our prospects, and our customers. We are very happy to perform this test, as it not only helps us make informed decisions, but also ensures greater transparency and trust among our customers.

"

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.

Yes – the AVILOO Battery Certificate can be seamlessly integrated into existing vehicle exchanges, sales platforms, or internal remarketing systems via API. This allows the battery state to be displayed directly in the listing – for greater transparency, trust, and higher closing rates.

An independent battery certificate provides objective assurance about the condition of the most important vehicle component – the battery. Studies and market analyses show that vehicles with documented battery health achieve higher sales prices and sell faster, especially electric cars with a good SoH rating.

Yes – the AVILOO FLASH Test is scalable and ideal for use in fleets, lease returns or used car inventories. For larger quantities, we offer customized processes, logistics solutions, and evaluations, including a dashboard overview and API connection.

The FLASH Test provides a quick assessment of the battery's state within 3 minutes – ideal for fleets and remarketing. The AVILOO PREMIUM Test analyzes the battery over a complete discharge cycle and provides the most detailed assessment – including SoH, range and certificate. The FLASH test accuracy is approx. ±3% compared to the PREMIUM Test.

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. It not only determines the actual SoH, but also checks the battery down to the individual cell level for possible defects and anomalies. Soon, each AVILOO Certificate will also include a visual heatmap showing the condition of every cell and highlighting any irregularities. This provides a complete picture of the functionality and safety of high-voltage batteries.
