VoltCert — Battery Health Certification & Pricing API for Used-EV Dealers, Lenders, and Marketplaces

The Problem

Used EV demand is real, but trust is still fragile.

Battery health behaves like the EV equivalent of engine condition, except buyers cannot judge it visually and most dealers still do a poor job explaining it. That creates slower sales, lower confidence, weaker financing terms, and price compression.

Recent signals are strong:

• Autotrader Insight says 64% of consumers worry battery health would stop them buying a used EV.
• Autotrader / Cox rolled EV battery health scores onto 19,000+ listings, validating that battery data now belongs directly in the merchandising layer.
• Ayvens launched used-EV State of Health certificates across multiple European countries including Portugal, explicitly citing battery transparency as a core barrier to EV adoption.
• ZETA / Recurrent says up to 500,000 EVs could come off lease in 2026 in the US alone, with nearly double in 2027; Europe is on the same structural path as lease fleets mature.
• AVILOO market evidence suggests certified used EVs can command £500-£1,000 more, expand the buyer pool from 61% to ~83%, and materially improve dealer trust and conversion.
