After more than six years of development and testing, ElectricFish Energy has introduced a grid-interactive electric vehicle (EV) charging architecture designed for deployment at existing fuel retail sites and other locations with constrained electrical infrastructure.
The system supports short dwell-time charging sessions of approximately eight to ten minutes, adding up to 180 miles of range. The architecture is designed to deliver high-power charging without requiring major utility upgrades or extended installation timelines.
Rather than drawing peak power directly from the grid, each charging unit operates from integrated onsite energy storage and actively manages energy flow between the battery, vehicles, and the grid. This approach decouples charging power from grid connection size, enabling fast charging while reducing peak demand on local distribution infrastructure.
Each unit integrates a 400-kWh battery with dual high-power DC fast-charging ports capable of delivering up to 400 kW, while requiring as little as 30 kW from the grid. Software-based controls manage charging schedules, energy buffering, and grid interaction, allowing the system to absorb demand spikes and support load shifting.
The system has undergone extended validation testing, including multi-month operation in high-temperature conditions at Hyundai Motor Company’s California Proving Ground during 2025. During MotorTrend’s 2026 SUV of the Year evaluations, the platform delivered more than 1,100 kWh across 37 charging sessions, with peak power exceeding 300 kW.
A commercial deployment is operational in Detroit’s Eastern Market district through the Toyota Mobility Foundation’s Sustainable Cities Challenge, supporting fleet electrification and public fast charging in a dense urban environment with limited electrical capacity.
