Generational vs Moba: Battery Test Comparison

Generational vs Moba

Two UK-active EV battery testing providers, with different paths to the same fundamental approach: both read the State of Health value the vehicle's Battery Management System has already calculated. The differences sit in certification, vehicle coverage, and partnerships.

Both rely on the BMS-reported SoH

Generational and Moba arrive at the SoH on their certificates by reading what the vehicle's own Battery Management System has already calculated.

• Generational's 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"¹.
• Moba's product page: their CARA Approval scope is that "the SOH provided by the Moba certificate is the same as the manufacturer's SOH"².

Both approaches are honest about what they do. The figure on the certificate is the manufacturer's number, faithfully transmitted.

Different scopes of CARA recognition

• Moba is on CARA Europe's approved providers list (Moba Certify Pro)⁹ — formal CARA Approval.
• Generational describes its methodology as "in line with the Car Remarketing Association Europe (CARA) guidelines"¹ — methodology alignment, not a CARA listing.

Generational does carry institutional partnerships and recognition: APC (Advanced Propulsion Centre), UKRI (UK Research and Innovation), the Department of Business & Trade, the Automotive Council UK, and IMDA⁸. These are research-funding, policy and trade-association bodies — distinct from CARA's product-level approval.

Vehicle coverage

Moba positions itself on coverage breadth, particularly for new Chinese brands using DoIP technology². This is increasingly relevant as BYD, MG and other Chinese manufacturers grow their UK market share.

Generational publishes a list of 40+ supported manufacturers and is "adding more vehicles to this list weekly"⁴.

What neither system provides

Both Generational and Moba arrive at SoH by reading the vehicle's BMS. Neither system independently calculates SoH from raw cell-level data; neither ships a cell-level severity heatmap as a standard certificate feature; neither holds independent engineering certification of the test methodology in the way TÜV provides.

For dealers who want an independently calculated SoH with a cell-level severity heatmap, backed by TÜV certification of the testing methodology, those features are available from AVILOO — the system Battery Health Check uses. The AVILOO Flash Test is also listed on CARA Europe's approved providers list⁹.
