AVILOO vs Generational: Battery Test Comparison
Compare AVILOO and Generational EV battery health tests. See how TUV-certified cell-level analysis compares to app-based OBD testing for UK dealers.
AVILOO vs Generational — How Do They Compare?
Both AVILOO and Generational offer EV battery health testing for the UK market, but they take fundamentally different approaches. AVILOO delivers TUV-certified, cell-level analysis through dedicated hardware. Generational uses an OBD dongle paired with a smartphone app.
Here is how they compare across the factors that matter most to dealers.
Side-by-Side Comparison
| Feature | AVILOO (Battery Health Check) | Generational |
|---|---|---|
| Test method | Dedicated AVILOO Box via OBD-2 | OBD dongle + smartphone app |
| Certification | TUV Nord + TUV Sud certified | No independent certification |
| Accuracy | +/-3% | Not independently verified |
| Test time | 3 minutes (FLASH test) | Approximately 5-10 minutes |
| Vehicle coverage | 95%+ of EVs and PHEVs | Growing coverage list |
| Cell-level analysis | Yes — individual cell heatmap | No — pack-level only |
| Price point | ~£35 per test | Variable pricing |
| Key partnerships | BCA, Cox Automotive, ADAC, Mercedes-Benz, Hyundai | Motorpoint, IMDA |
| Unique advantage | Only TUV-certified test worldwide | Car Dealer Power Award winner |
What Generational Does Well
Generational has built strong momentum in the UK market. They won the Car Dealer Power Award, which reflects genuine dealer satisfaction. Their government backing through the Advanced Propulsion Centre (APC) and UK Research and Innovation (UKRI) lends credibility to their research and development.
The Motorpoint partnership demonstrates their ability to win large dealer accounts. Their app-based approach means no specialist hardware beyond an OBD dongle, which keeps the barrier to entry low. The IMDA partnership adds a data and analytics dimension that some dealers find valuable.
Where AVILOO Leads
TUV Certification
AVILOO is the only battery health testing provider in the world with dual TUV certification (TUV Nord and TUV Sud). This is not a self-awarded badge — it means the testing methodology has been independently audited and certified to meet rigorous standards. In a dispute scenario under the Consumer Rights Act, a TUV-certified certificate carries substantially more weight than an uncertified app-generated report.
Cell-Level Analysis
AVILOO tests analyse each individual cell within the battery pack, producing a visual heatmap that shows the condition of every cell with severity indicators. Generational operates at the pack level, meaning it can tell you the overall state of health but cannot identify individual cell degradation or anomalies. Cell-level visibility matters because a pack can show acceptable overall health while individual cells are degrading — and those cells are what cause failures.
Proven Scale
With 550,000+ tests completed globally across 30+ countries and 750+ clients, AVILOO's methodology is proven at a scale that no UK-only provider can match. Named enterprise clients include BCA, Cox Automotive, ADAC, Hyundai, Mercedes-Benz, and Emil Frey. This is not a startup testing a hypothesis — it is a mature platform backed by a EUR 30 million investment from Armira Growth.
Energy-Based State of Health
AVILOO calculates State of Health using an energy-based methodology rather than relying solely on capacity metrics. This provides a more accurate picture of real-world battery performance and range capability.
The Bottom Line
Generational offers an accessible, app-based solution that works well for dealers wanting a quick, low-friction entry point. However, for dealers who need legally defensible certification, cell-level diagnostic detail, and the credibility that comes with independent TUV certification, AVILOO through Battery Health Check is the stronger choice.
When the average EV battery dispute costs £6,193 and replacements run £12,000 to £25,000+, the quality and credibility of your test certificate is not a detail — it is your primary line of defence.
