NIO will begin internal testing of its fifth-generation battery swap stations in late March, with 5-10 pioneer stations between May and June and mass rollout in July-August 2026. The target: over 1,000 new stations in 2026, adding to the 3,763 currently operational across China.
The fifth-generation design addresses a fundamental limitation of previous stations: wheelbase compatibility. The new architecture supports everything from NIO's full-size ES9 to the compact Firefly brand, meaning a single station can serve vehicles across NIO's three brands without hardware modifications.
Improvements Over Gen 4
Fourth-generation stations hold 23 battery bays and handle up to 480 daily swaps with a 22% reduction in per-swap service time. The fifth generation adds a 20% capacity increase over that baseline, which translates to roughly 576 daily swaps if the service time holds.
NIO added 679 stations in 2024 and 681 in 2025. The 1,000+ target for 2026 represents a significant acceleration. The company is also shifting toward highway exit station placement for dual-market coverage and an asset-light partnership model for cost-sharing.
Manufacturing
New stations will be manufactured in Wuhan's Optics Valley. The Hubei province specifically is expanding from 139 to 200 stations in 2026.
NIO's swap network remains the largest differentiator against every other Chinese EV brand. The fifth-generation stations are designed to scale that advantage across a broader vehicle portfolio, from the sub-compact Firefly to whatever comes after the ES9.
