The recurring dream in grid power electronics is the "energy router" — one box that intelligently routes power among everything connected to it. US12472836B2, granted to Georgia Tech Research Corporation on November 18, 2025, claims a multiport energy-routing system that chases exactly that vision.
The CPC tags reveal the application: B60L 53/30, 53/51, 53/53, 53/60 are all EV charging-station infrastructure, and H02M 3/335 is the isolated DC-DC converter doing the work. This is a device aimed at EV charging hubs — a single multiport converter that ties the grid, on-site storage, and multiple charging ports through shared power electronics instead of a separate converter for each.
Why this maps to a real grid problem: a fast-charging hub with many ports, plus on-site storage to buffer the grid connection, is otherwise a tangle of separate converters, each with its own losses and cost. A multiport router consolidates them, routing power directly between any two ports — battery to car, grid to battery, solar to grid — minimizing conversion stages. It is the same consolidation logic as the solid-state transformer, applied to charging.
The patent-versus-product caution is firm: this is university research IP, fencing an architecture, almost certainly ahead of any deployed product. It claims a routing system, not a shipping charging hub. Reading it as a commercial device would be the category error this desk exists to flag.
From patent to grid, the energy-router concept connects to the deployment story through EV charging hubs and microgrid interfaces — the places where many power flows meet and where consolidating converters into one intelligent box pays off. Georgia Tech's 2025 grant, alongside the Sandia and Hitachi SST work in the same year, marks a 2025 cluster of IP around the one-box grid-interface idea. The academy and the labs are fencing the architecture; whether and when it ships is a separate, harder question.
