Aviloo launches next-gen battery certificate

The revamped offering, available from 23 June, promises a new level of accuracy and usability in assessing the health of batteries in electric and plug-in hybrid vehicles. At the heart of the update is a redesigned battery certificate, now bundled with the ‘Aviloo Certified’ seal – a quality mark designed to instil confidence in used EV transactions, the company says.

Aviloo has developed a manufacturer-independent diagnostic procedure for traction batteries in electric and plug-in hybrid vehicles. It says that the revised diagnostic process delivers results faster and in a more intuitive format through what it calls the ‘Aviloo Preview’.

Unlike many OEM-based tools that simply extract data from the vehicle’s internal system, Aviloo independently calculates the battery’s State of Health (SoH). This distinction is crucial, the company states, as it enables far more granular analysis and helps identify “red flags” that might otherwise go undetected. Enhanced algorithms and a rapidly expanding test database – growing since 2019 – now underpin the latest version of the ‘Flash Test’, providing a richer, more precise data foundation.

The updated battery certificate now also includes benchmarking metrics, comparing the tested battery’s performance to others of the same make, age, and mileage. This is made possible by Aviloo’s extensive dataset, which includes hundreds of thousands of entries from global test cycles. The certificate introduces a heatmap that displays the condition of each battery cell, highlighting any anomalies with severity indicators—enabling users, including non-specialists, to interpret results at a glance.

Another new feature is real-world range reporting. Aviloo states that the test certificate now displays the vehicle’s achievable range, benchmarked against WLTP values and peer vehicles from the company’s database. This gives customers an immediate sense of how the EV is likely to perform under actual driving conditions, removing guesswork from purchasing decisions.

“The Aviloo battery test elevates battery diagnostics to a new technological level,” says CEO Marcus Berger. “Through our detailed analysis process, customers receive an accurate and independent assessment of their vehicle’s battery health—something that cannot be achieved through a standard SoH readout.”

Furthermore, Berger underscores the broader market impact: “An international study from 2024 shows that recognised, independent battery certificates lead to profit increases of €550 to €1,100 for dealers. More importantly, customers place greater trust in remarketers who use Aviloo – making used EV sales both faster and more secure.”

The enhanced certificate will be automatically activated for existing FLASH Test license holders at no extra cost. Target users include fleet operators, leasing firms, auction houses, and used car dealers—all stakeholders in a second-hand EV market that is becoming increasingly competitive and regulation-driven.

Aviloo currently offers two different tests – the ‘Flash Test’ and the ‘Premium Test’. The latter test is a more complex procedure, where the ‘Aviloo Box’ collects detailed measurements of the vehicle’s battery during a test drive. The ‘Flash Test’ also uses the ‘Aviloo Box’, but is carried out within three minutes while the vehicle is stationary. The box reads several parameters from the vehicle and compares them with previously recorded comparative data from similar vehicles.
