New Battery Certificate - how AVILOO Is Transforming the Used Electric Vehicle Market

Since June 2025, AVILOO customers have benefited from an even more precise and intelligent battery diagnostic system that not only brings greater transparency to the used EV market, but also turns the often-cited obstacle of the EV battery into a true selling point—thanks to the independent battery certificate.

The electric vehicle market is evolving at a remarkable pace. Alongside the surge in new EVs, used electric cars and plug-in hybrids are becoming increasingly attractive to buyers. This shift brings a growing demand for transparency, safety, and clarity—especially when it comes to battery health, the most critical factor in determining the value and reliability of a used electric vehicle.

A New Standard in Battery Diagnostics

AVILOO has responded to this challenge with a pioneering solution: independent battery diagnostics that go far beyond conventional readout methods. Unlike traditional BMS data providers, AVILOO’s technology can detect potential damage down to the cell level, delivering a significantly more precise and trustworthy assessment. To further increase transparency in the market, AVILOO introduced the AVILOO CERTIFIED battery certificate. This certificate is awarded to vehicles that pass the FLASH Test—a fast, user-friendly diagnostic test that provides reliable results in just three minutes. If the battery shows no irregularities, the vehicle receives the AVILOO CERTIFIED seal, offering buyers confidence and giving sellers a strong unique selling proposition.

Independent and Accurate Battery Assessment

What sets AVILOO apart is its independent calculation of the battery’s State of Health, rather than relying on values extracted from the vehicle itself. This ensures an objective and accurate assessment that cannot be achieved through standard methods. The FLASH Test uses AI-trained adaptive models to deliver intelligent and reliable diagnostics for EV batteries. The certificate brings clarity to a market often perceived as confusing and inconsistent, helping buyers avoid costly mistakes and enabling sellers to present their vehicles with confidence. Additionally, thanks to the benchmarking model, customers receive a valid assessment of how their vehicle’s battery compares to batteries in similar vehicles. AVILOO offers the broadest vehicle coverage available on the market—currently covering over 96 percent of common electric and plug-in hybrid vehicles (EVs and PHEVs).

 

Study-Driven Impact and Market Value

The effectiveness of AVILOO’s certification is backed by compelling data from its international Remarketing Study conducted in 2024. The study revealed that buyers are willing to pay significantly more—between €550 and €1.100—for a used EV that includes a certified battery report. It also showed that more than half of potential buyers who previously preferred new EVs would consider purchasing a used one if an independent certificate were available, increasing the pool of interested buyers from 61% to approximately 83%. Furthermore, the likelihood of selling a certified vehicle rises by around 36 percent, underscoring the certificate’s impact on market dynamics. For dealerships, the benefits are even more pronounced, with 81 percent of customers reporting higher levels of trust in dealers who offer battery certification.

Real-World Success with AVILOO Partners

AVILOO’s impact is already visible in the market. Manheim Express Europe, for example, recorded a 29.3 percent increase in bids per vehicle, a 22.4 percent rise in active bidders, and a 33.4 percent boost in sales conversion—all within just nine months of integrating AVILOO’s certification into their sales process. Similarly, BCA reported up to a 50 percent increase in click-through rates when listings included AVILOO battery certificates. A survey conducted by mobile.de confirmed that over 60 percent of respondents felt that a battery certificate would positively influence their trust and purchasing decision.[1]

A Clear Advantage for the EV Market

As Marcus Berger, CEO of AVILOO, explains, the uncertainty surrounding battery condition, the single most important factor influencing a vehicle’s residual value, remains a major obstacle for many buyers of used EVs. AVILOO’s test solutions close this gap, offering security for buyers and increased profitability for resellers. The certification simplifies the buying and selling process, making used EVs easier to compare and helping to avoid costly mistakes.

In a market where trust and transparency are paramount, AVILOO’s independent battery certification provides a clear and measurable advantage. It empowers buyers with confidence and gives sellers a compelling tool to stand out in an increasingly competitive landscape. For anyone involved in the resale of electric vehicles, AVILOO is setting a new standard for quality, reliability, and trust.
