AVILOO vs Generational: Battery Test Comparison

AVILOO vs Generational

AVILOO is the world's first independent, TÜV-certified battery diagnostic system for electric vehicles¹, used by 750+ clients across 30+ countries, with 550,000+ tests to date². The AVILOO Flash Test is also CARA Approved¹⁴.

Generational is a UK-focused battery test that reports the State of Health value already calculated by the vehicle's own Battery Management System³.

That difference — independent calculation versus reading what the car's own software already says — is the most important thing to understand on this page. Everything else flows from it.

Independent calculation vs. reading the BMS

The single most important difference between the two systems is how the State of Health figure on the certificate is produced.

AVILOO independently calculates SoH from raw cell-level data captured during the test. AVILOO's algorithms process up to one million data points per test, drawn from a database of 550,000+ vehicle tests. The certificate's SoH figure is AVILOO's own calculation, not the vehicle's.⁴

Generational reports the SoH figure produced by the vehicle's own software. Per Generational's own user guide: their test "reports the State-of-Health from the vehicle's Battery Management System (BMS), which yields the same value as using an official manufacturer diagnostic tool."³

This is why AVILOO's test takes 3 minutes and Generational's takes 2: AVILOO is performing analysis; Generational is retrieving data the vehicle has already calculated.

For dealers, the practical question is: if a buyer's solicitor disputes the SoH figure on the certificate, where did that figure come from? A figure independently calculated by a TÜV-certified diagnostic system is a different answer to that question than a figure read directly from the vehicle's own Battery Management System.

Two kinds of formal credential

TÜV NORD and TÜV SÜD are independent engineering certification bodies. Their function is to audit products and methodologies against published technical standards and to issue formal certification. TÜV is the certification body that signs off the German MOT-equivalent vehicle inspection. Their credentials are accepted as evidence in regulatory and contractual proceedings across the EU and globally.

AVILOO is TÜV-certified. AVILOO's official marketing flyer describes the system as "Manufacturer-independent · TÜV-certified"¹. The TÜV SÜD partnership has been in place since April 2022 — TÜV SÜD applies its brand to the joint offering¹² — and TÜV NORD is also an AVILOO partner¹³. AVILOO further claims, with corroboration in independent press, to be "the world's first independent, TÜV-certified battery diagnostics system for electric vehicles"¹.

AVILOO also appears on CARA Europe's approved providers list. The AVILOO Flash Test is listed by CARA as an approved diagnostic system for the European remarketing industry¹⁴, alongside Moba Certify Pro, Power Cruise Control, Autel Blitz Test, MAHLE E-SCAN, vsNEW, and DEKRA. The TÜV certification of AVILOO's methodology and the CARA listing of the AVILOO Flash Test are separate credentials issued by separate bodies for separate purposes.

Generational holds methodology alignment, not a CARA listing. Generational describes its methodology as "in line with the Car Remarketing Association Europe (CARA) guidelines"³, but Generational does not appear on the CARA approved providers list¹⁴. Its homepage lists APC, UKRI, the Department of Business & Trade, the Automotive Council UK and IMDA as institutional partners⁸.

These are different kinds of bodies:

• TÜV is an independent engineering certification body — its credential attaches to the testing methodology itself.
• CARA is a trade association that publishes industry best-practice guidelines.
• APC and UKRI are R&D funding bodies that distribute innovation grants.
• The Department of Business & Trade and the Automotive Council UK are policy / industry-direction bodies.
• IMDA is a UK trade association of independent motor dealers.

None of those bodies perform engineering certification of testing methodology. Funding, membership, and alignment with guidelines are valuable signals of industry credibility — they are a different category from independent engineering certification of a test methodology.

Cell-level analysis

Both systems can now report at the cell level. The difference is maturity and visualisation.

AVILOO introduced a cell-level heatmap to its certificate in June 2025. Independent press at launch described it as 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"⁴. The heatmap appears on every AVILOO certificate.

Generational announced cell-level voltage testing in April 2026, ten months after AVILOO. Generational describes the capability as measuring "voltage balance across individual cells" with anomaly flags¹¹. As of 5 May 2026, we have not located a published description of the visual format used for Generational's cell-level output.

Scale

AVILOO operates at global scale. Per the February 2026 funding announcement: more than 550,000 cumulative tests to date, over 750 clients across more than 30 countries, growing at "more than 100% year-on-year"². Mercedes-Benz and Hyundai have integrated AVILOO diagnostics into their dealer ecosystems⁷. AVILOO secured €30 million of strategic investment from Armira Growth in February 2026².

Generational is UK-focused. Per the January 2026 Motorpoint rollout coverage: 1,500+ vehicles tested in the Motorpoint trial; Motorpoint deployment covers 21 stores plus two preparation centres⁶. Other named UK customers include Smith Motorgroup, Cambia Automobiles, Carbase, Available Car, Motorparks, John Grose Group, and Tracks Suzuki⁸.

The bottom line

If a buyer's solicitor under the Consumer Rights Act 2015 challenges the SoH figure on the certificate, the dealer needs an answer to one question: what evidence backs that figure?

• AVILOO's certificate carries an independently calculated SoH, supported by TÜV certification of the testing methodology and a place on the CARA Europe approved providers list, drawn from a global dataset of more than 550,000 cumulative tests across more than 30 countries.
• Generational's certificate carries the SoH figure produced by the vehicle's own Battery Management System, with methodology in line with CARA's industry guidelines but not on the CARA approved providers list.

Both are real products with real customers. Battery Health Check chose AVILOO because, on the question of what evidence sits behind the SoH figure on the certificate, AVILOO is the system that produces an independent answer.
