The installation marks the first operational deployment of Supernova PowerRing, Wallbox’s new intelligent fast-charging architecture introduced in late 2025. Designed to optimize power distribution across multiple chargers, PowerRing enables operators to scale fast-charging infrastructure more efficiently while making better use of available grid capacity.
The system installed at Port de Sitges includes three Supernova chargers designed to support a shared dynamic capacity of up to 240 kW once fully enabled. The PowerRing architecture is designed to automatically allocate available power across the chargers depending on the number of vehicles charging simultaneously, allowing each vehicle to receive between 80 kW and 240 kW based on demand, vehicle compatibility and available capacity.
Supernova PowerRing is designed to deliver high-power charging in a more flexible and efficient way. The system can provide up to 400 kW to a single vehicle, provided the vehicle is compatible and sufficient power is available within the system’s shared capacity, which can reach up to 720 kW. This dynamic approach allows operators to maximize charging performance while reducing the space, cost and infrastructure complexity typically associated with high-power charging sites.
“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.”
Thanks to its modular and compact design, Supernova PowerRing is suitable for a wide range of locations, including retail destinations, parking facilities, service stations, marinas, urban charging hubs and other high-traffic environments where space and power availability are key constraints.
The deployment at Port de Sitges forms part of Wallbox’s progressive rollout of Supernova PowerRing across European markets, as the company continues to expand its fast-charging portfolio for public and semi-public charging applications.
