Combating Standby Losses in High-Intermittency EV Charging
On September 28, 2026, Chubu Electric Power Grid and Fuji Electric announced the commercial deployment of their next-generation amorphous alloy core pad-mounted distribution transformers. With fast-charging EV stations experiencing extended standby periods between charging cycles, continuous no-load core losses represent a substantial waste of energy in conventional silicon-steel transformers.
The newly developed amorphous ribbon exhibits an atomic random structure that lowers hysteresis loss dramatically, reducing standby power consumption by 60% compared to Top-Runner standard Japanese distribution units.
Compact Enclosure Design and Thermal Resilience
Amorphous cores are notoriously sensitive to mechanical stress and require larger cross-sectional areas. Fuji Electric solved this by engineering a modular wound-core geometry with automated stress-relief annealing and synthetic ester insulation fluid.
The complete pad-mounted package fits within standard pavement utility footprints and is rated for 150% temporary peak overloading to absorb simultaneous ultra-fast EV vehicle arrivals without thermal degradation.
