Wallbox has switched on its first Supernova PowerRing fast-charging installation at Port de Sitges, a high-traffic site on the Mediterranean coast near Barcelona, deploying three Supernova chargers that share a dynamic capacity of up to 240 kW once fully enabled. The site marks the first operational use of the PowerRing architecture, which Wallbox introduced in late 2025 to spread power across multiple chargers based on real-time demand. The company reports that the system allocates available power automatically depending on how many vehicles are charging at the same time.
Highlights
- Wallbox’s first operational Supernova PowerRing deployment is now running at Port de Sitges, near Barcelona.
- The site uses three Supernova chargers sharing a dynamic capacity of up to 240 kW once fully enabled.
- Each connected vehicle can draw between 80 kW and 240 kW, depending on demand, compatibility and available capacity.
- The wider PowerRing architecture is designed to deliver up to 400 kW to a single vehicle and up to 720 kW in shared capacity.
How the PowerRing System Distributes Power
Wallbox built Supernova PowerRing to scale fast charging without overbuilding a site’s grid connection. At Port de Sitges, the three chargers draw on a shared pool of up to 240 kW, and the architecture divides that capacity across the units according to how many cars are plugged in. According to the company, each vehicle can receive between 80 kW and 240 kW, set by demand, vehicle compatibility and the power free at any given moment.
The design scales well beyond the Sitges configuration. Wallbox says the architecture can deliver up to 400 kW to a single compatible vehicle when enough power is available, drawing on a shared system capacity that can reach 720 kW. The company laid out those figures when it launched the PowerRing platform in late 2025. It describes the dynamic approach as a way to raise charging performance while reducing the space, cost and infrastructure complexity usually tied to high-power sites.
Built for Space-Constrained Locations
PowerRing pools power across Wallbox’s Supernova fast chargers, and its modular, compact form is aimed at sites where space and grid capacity are tight. The company lists retail destinations, parking facilities, service stations, marinas, urban charging hubs and similar high-traffic settings as suitable locations.
“This first deployment is an important milestone for Supernova PowerRing and demonstrates how this technology can help operators deploy fast-charging infrastructure in a more efficient and flexible way,” said Eduard Castañeda, Chief Product & Technology Officer and Co-founder of Wallbox. “PowerRing has been designed to help operators optimize available power, scale their charging networks and maintain a high-quality charging experience for users.”
Part of a Wider European Rollout
The Port de Sitges installation is the start of a phased rollout of Supernova PowerRing across European markets, as Wallbox expands its fast-charging portfolio for public and semi-public charging applications.
