To a large extent, the value of electric vehicles depends on the condition of the battery. Especially when buying used cars, customers are interested in the residual value of the most expensive component of the vehicle. Aviloo launched a device in 2020 that certifies the value of used electric vehicles for buyers and dealers through an independent battery test. Fundamental statements about the "health status" can be made in just a few minutes with this self-developed device. With the "industry-leading technology," the aim is to promote the trade of used electric vehicles and increase trust among buyers. Now, the Lower Austrian company has expanded its solution, which it claims to be a global industry standard supporting 95 percent of all common EV and PHEV models, promising "even more transparency, security, and clarity in the used electric vehicle market."
The update will be newly introduced on June 23, 2025. Certified with the Aviloo Certified seal of approval, customers will then have access to an even more informative battery diagnosis. According to the press release, the solution is intended to be even more distinct from other reading procedures available on the market. The update is available to customers at no additional cost and will be automatically activated for all test license holders such as car dealers, fleet operators, and leasing companies.
After three minutes in the mailbox
The Flash Test, which only takes a few minutes, is now supposed to work more efficiently and precisely in the revision and provide more information about the vehicle condition. The appearance was also refreshed
on this occasion for easier understanding of the Aviloo Preview for both experts and laypeople. The usual speed of diagnosis remains unchanged: it still takes about three minutes for the certificate to land in the email inbox after plugging in the Aviloo test box.
The provider highlights a total of six points for the Aviloo relaunch:
Aviloo Certified Seal of Approval
The certificate is now newly provided with a new quality seal. It is meant to signal risk-free EV (Electric Vehicle) used car purchases if there are no defects or anomalies, thus creating "clarity, trust, and security for all market participants."
More precise SoH indication
The State of Health (SoH) is now supposed to be even more precisely determinable due to better data and optimized algorithms. This is because Aviloo's database has already grown significantly since the beginning of data collection in 2019 and continues to increase. This enables continuous and even more precise analysis, which can help solidify maximum security in battery diagnostics. And to prevent customers from buying a defective vehicle, the Flash Test provides a "Red Flag" report when the software detects "substantial risks."
Comparison possibility
For the first time, users also receive a benchmarking overview with the battery certificate. This shows in which capacity range the analyzed battery lies compared to comparable vehicles, for example, with the same battery size, similar mileage, or the same age.
Insight into the cell level
With the new "Heatmap," users also gain insight into the condition down to the cell level of the batteries: any present anomalies are detected
and the result visualized. "Possible defects and their location are graphically represented," the description says: The "cell voltage diagram" shows at a glance how many and which cells are affected and to what extent. In an intuitive representation, the "difficulty level of the anomaly" is also clearly recognizable for non-experts.
Three range indications
For the first time, the battery certificate is also supposed to provide information about the "real" possible range of the vehicle. This value is compared with the worldwide standardized WLTP (Worldwide Harmonized Light Vehicles Test Procedure) value, which is considered particularly accurate. The WLTP measurement procedure, used to determine consumption and emission values, calculates the maximum distance the vehicle can realistically travel with a fully charged battery based on certain factors. In addition to its own and the WLTP range results, the application also shows the typical ranges of comparable vehicles from Aviloo’s database.
Quick clarity about results
The test values determined in the self-explanatory plug-and-play procedure can then, according to the provider, be just as easily and quickly evaluated. This works via the Aviloo Preview, which graphically displays an overview of the most important results of the battery certificate from the Flash Test. This allows for quick uploads to sales platforms to make the information quickly available. Further security is supposed to be provided by the feature as it confirms the technical inspection of the drive battery conducted by Aviloo and visually represents the independently determined health status (SoH) of the vehicle, demonstrating that the central battery functions have been verified.
Aviloo CEO Marcus Berger
summarizes the uniqueness of the newest version:
"With Aviloo’s battery test, battery diagnostics are brought to a new technological level. With our detailed analysis procedure, customers receive an exact and independent picture of the health status of their vehicle, which would not be possible with a conventional SoH reading in this way. Because only Aviloo calculates the SoH itself and independently and does not just read out a value from the vehicle."
Such information gives both buyers and sellers security and is apparently worth real money. In 2024, an international study showed that the use of such independent, recognized battery certificates increased dealers' profits by at least 550 to 1,100 euros. Berger:
"End customers develop greater trust in remarketers who offer an Aviloo certificate, and due to the provided security and transparency, a larger percentage of end customers are willing to purchase a used EV. Therefore, it’s a win-win situation for all market participants, ultimately benefiting everyone."
After a short start-up period, the battery test expert founded in 2018 is, according to its own information, the world market leader in battery diagnostics for E-cars and plug-in hybrid vehicles and offers the "fastest comprehensive diagnostic solution currently on the global market" with its Flash Test. Aviloo, whose TÜV and Cara-certified application is used by numerous associations and companies in the automotive industry, has also been cooperating since autumn 2024 with the Central Association of the German Motor Vehicle Industry (ZDK). The association advocates for greater popularity of electric vehicles and aims to enhance trust in e-mobility through supporting reliable battery
