The AVILOO FLASH Test is designed as a plug-and-play solution and can be easily integrated into existing processes. Installation takes only a few minutes – after that, the test runs in the background during normal vehicle operation.
Yes – we provide business customers with an online dashboard where you can easily manage, download, and evaluate all tests performed, vehicle data, and certificates. An API connection to your system is also available on request.
No. Regardless of the reason why multiple tests were performed on a vehicle within two hours, only one test per vehicle use will be charged. You will receive a single invoice for the VIN in question.
Yes! We regularly offer free live demonstrations and webinars. Just give us a call or send us an email, and we will find a suitable date:
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.
