Scottish semiconductor and battery intelligence firm Dukosi has announced a partnership with Kia Europe to deliver the carmaker’s first public trial of a cell-level battery passport.

The trial uses a Kia EV3 fitted with Dukosi’s battery cell monitoring system, which transmits live data from each individual cell to a digital battery passport. The passport allows drivers, mechanics, and regulators to view real-time information on the battery’s State of Health (SoH), automatically updating after maintenance or repairs to ensure full traceability.

By monitoring at a cell level, Kia’s system seeks to enable earlier fault detection, cheaper targeted repairs, and greater trust in the used EV market. The research, coordinated by Delft University of Technology with support from Hyundai Motor Group and partners including TNO, tests how digital battery passports can securely share data between multiple stakeholders.

Mark Hedrich, President and CEO of Kia Europe said in the announcement: “Kia aims to set a new standard for customers regarding battery transparency and performance. Through testing cell-level battery passports, we gain insights on what ownership benefits we can offer our customers. On top of advantages such as extended battery life, we will be building on a relationship of trust as well.”
