<p>Nio has delayed the mass rollout of its fifth-generation battery swap stations to summer but aims to add 1,000 units this year. Internal testing will begin in late March, with five to ten pioneer stations planned for May and June. The redesign allows support for larger vehicles and the Firefly sub-brand. Despite the delay, Nio operates 3,763 stations in China and is focusing on partnerships to manage costs. The new stations will be manufactured in Wuhan, with an increase in Hubei from 139 to 200 stations planned for this year.</p>

- Nio has postponed the mass rollout of its fifth-generation battery swap stations to July and August, while still aiming to add 1,000 units this year.  
- The company plans to start internal testing of these redesigned stations in late March and expects the initial five to 10 trial stations to operate between May and June.  
- This delay is due to the need for a complete redesign to accommodate various vehicle sizes, including those from its Firefly sub-brand, as Nio continues to refine its infrastructure strategy in response to past expansion rates.
