AVILOO, an Austrian diagnostics firm, has published the largest independent study of used-EV battery health, analyzing data from over 500,000 vehicles. The research provides critical, real-world benchmarks for battery degradation across multiple makes and models up to 150,000 kilometers.
The study identifies the Mercedes EQA, Hyundai IONIQ 5, and BMW i4 as having the best battery health retention among all tested vehicles. These models demonstrated superior management of cell chemistry and thermal conditions, directly correlating with slower capacity loss over time and mileage.
For fleet operators, logistics companies, and energy storage procurers, this data offers an objective foundation for procurement decisions. Understanding which EV platforms maintain higher state-of-health (SoH) directly impacts total cost of ownership, resale value, and the feasibility of second-life battery applications.
This means that B2B clients can now prioritize vehicle models with proven long-term performance, reducing financial risk associated with battery replacement and ensuring more predictable operational range. The study's findings underscore the importance of advanced Battery Management Systems (BMS) and cell chemistry selection in maximizing ROI for commercial EV adoption.
