The Aria EV Shows the Potential of EV Battery Swapping

The Aria EV, built by students at Eindhoven University of Technology, challenges conventional EV design by prioritizing repairability. Its 13 kWh battery is split into six ~12 kg swappable modules secured under the floor with bottom-latch systems and high-voltage interlocks, allowing a single person to replace them safely. A companion diagnostic app accessed via USB-C provides 3D fault visualization and step-by-step repair instructions. Experts note that external modularity introduces added interfaces, mass, and validation complexity around thermal management, crash integrity, and high-voltage isolation. The concept faces headwinds from industry trends toward integrated battery structures, consumer demand for range and low cost, and the need for regulatory and supply chain changes—but right-to-repair legislation could create new incentives for this approach.
