To begin, we suggest the Flash Test. It's the most efficient way to get a quick and accurate overview of your EV battery's health, identifying any immediate red flags.
If the Flash Test highlights any areas of concern, the Premium Full Test provides an exhaustive deep-dive. This comprehensive analysis will give you a detailed report, pinpointing the exact nature of the issue and providing the data needed for a complete evaluation.
Please note, the Flash Test and the Premium Full Test are two separate services. Both are charged individually.
We support all major electric vehicle brands including Tesla, Nissan, BMW, Chevrolet, Hyundai, Kia, and more. Contact us to confirm compatibility with your specific model.
The manufacturer-independent, objective AVILOO Diagnostic Test is available for both fully electric vehicles and plug-in hybrid vehicles.
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 FLASH and 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.
