Qnovo Pilots Battery Genome Application to Assess EV Batteries for EU Passports
The application uses in-vehicle electrochemical data to identify hidden defects and project residual value ahead of the 2027 regulatory deadline.
Battery software provider Qnovo has begun piloting a new application built on its Battery Genome database, designed to assess the condition and residual value of electric vehicle batteries. The move comes as automakers prepare for the European Union’s upcoming digital battery passport requirements.
What Happened
Qnovo’s new application leverages its Battery Genome, a database described by the company as containing data from all battery types across major manufacturers and billions of real-world charge-discharge cycles. By analyzing the full electrochemical record inside the vehicle—including charging behavior, operating history, environmental exposure, and cell-level variation—the application aims to identify markers of accelerated aging and hidden defects. This process generates a risk-adjusted view of the battery, including projections of how it is likely to age and its resulting residual value. The pilot is being conducted in collaboration with automotive OEM partners.
Why It Matters
The EU’s digital battery passport requirement takes effect on February 18, 2027, for every EV battery placed on its market. Qnovo argues that current aftermarket data is too sparse to distinguish between batteries that have aged differently due to specific driving profiles or environmental conditions, leaving used EVs priced on uncertainty. If a battery fails after being declared healthy based on limited data, it creates a liability for the automaker certifying the passport. By running the analysis in-vehicle where rich data resides, Qnovo states the application provides OEMs with greater certainty about field performance and confidence in their assessments. The company is positioning this tool for OEMs, fleet operators, and insurers as an extension of its existing software stack, which includes Adaptive Fast Charging and Health and Safety Diagnostics.
The Bottom Line
Qnovo is testing a data-driven approach to battery valuation ahead of strict EU regulations. The pilot aims to resolve the discrepancy between superficial battery health metrics and actual electrochemical aging, potentially reducing liability risks for manufacturers and improving transparency in the used EV market.
