Wallbox launches 400 kW Supernova PowerRing

According to Wallbox, the PowerRing links several Supernova chargers within a single network that distributes power dynamically between outlets. Each configuration can include up to three Supernova units and six charging points, allowing installed capacities of 240, 480, or 720 kW. Unlike systems such as the Alpitronic Hypercharger HYC1000 or Tesla Superchargers, Wallbox Chargers’ solution does not use a central cabinet with power modules. The modular design is intended to let operators adapt installations to site conditions and expand capacity as required.Wallbox Chargers offers the Supernova in variants with 80, 160 and 240 kW maximum charging power. Up to three of these charging columns, each with two DC charging points, can be networked within the modular PowerRing system. Depending on the configuration, each installation thus provides up to 240, 480 or 720 kW. Up to 400 kW per charging point is said to be possible – referring to the maximum configuration using the Supernova 240.Interestingly, although the Supernova 240 on its own only delivers up to 240 kW, a company spokesperson told electrive that within the PowerRing system, the stated charging outputs of up to 400 kW at a single charging point should nonetheless be achievable. Wallbox Chargers has not made any changes to the Supernova’s hardware specifications. “The output of 400 kW per connector stems from the PowerRing architecture, which manages power distribution across several Supernova units linked via a central control and energy-management system,” the spokesperson said. The company did not explain exactly how this works, given that a single charging column is technically designed for 240 kW and no hardware adjustments are said to have been made.The first phase of the PowerRing introduces power sharing between units, allocating unused capacity to active charging sessions. Wallbox states that this approach can help maintain high availability, manage power demand during peak use, and streamline installation. Subsequent development phases are planned to enable simultaneous power sharing between connectors, followed by site-level energy distribution to optimise utilisation and driver experience. The company has also left open how exactly the first and second phases differ.Wallbox plans to begin the phased rollout of the Supernova PowerRing in early 2026, initially in Southern Europe, Benelux, and the UK and Ireland, with further markets, including the United States, to follow.“Operators need charging systems that make economic sense today while being ready for the future,” said Eduard Castañeda, Chief Product & Technology Officer at Wallbox. “Supernova PowerRing was designed to do exactly that, delivering flexibility, performance, and reliability, all within a remarkably compact footprint.”“Supernova PowerRing is designed to redefine how charging infrastructure can scale efficiently,” added Castañeda. “It allows operators to serve more drivers with less space, less cost, and less complexity, while maintaining a focus on charging speed and user experience.”businesswire.comWith reporting by Daniel Bönnighausen for electrive’s German edition.
