At the historic intersection of energy transition and transport electrification, ultra-fast charging stations are springing up across the country. When hundreds of kilowatts—even megawatts—of demand converge on a single site in a single moment, the local grid faces a stress test it was never designed to pass.
Energy storage has therefore stepped from the wings to center stage. It is no longer an accessory; it is the ballast that steadies the grid and the key that unlocks operational efficiency and economic upside.
Spurred by policy and the market, China is hurtling toward “gasoline-electric parity.” The national EV-refueling network has officially entered the “high-power era.”
Ultra-fast charging places a severe strain on grid capacity. In districts with aging distribution networks, peak demand at a single station can spike to three-to-five times the normal peak—or more. Voltage at the connection point can drift beyond safe limits, disrupting nearby households or, worse, triggering protection relays and regional blackouts.
Existing distribution grids were engineered for steady residential and industrial loads. To accommodate the random, concentrated surges of ultra-fast chargers, utilities would have to “hard-expand”—uprating transformers and reconductoring lines at costs that can run into millions per site. Economics and project timelines make this prohibitive.
Kortrong's multi-energy complementary ultra-charging solution delivers a triple breakthrough: grid compatibility, charging efficiency, and economic viability.
Grid Resilience: The system integrates energy storage as a "flexible buffer," combined with a medium-voltage microgrid and intelligent power distribution algorithms. This enables 10-millisecond response times for dynamic capacity expansion, eliminating grid instability risks.
Revolutionary Efficiency: Featuring a high-voltage direct-connection design, the system bypasses traditional AC-DC conversion stages, achieving 98.5%+ conversion efficiency—3-5% higher than conventional systems. With megawatt-level DC output at 1000V, it fully charges heavy-duty trucks in 10 minutes, redefining speed standards.
Amid power market reforms, energy storage is evolving into a strategic asset. Kortrong's multi-energy complementary ultra-charging solution maximize value through:
On-site renewable consumption: Solar power generation reduces base electricity costs.
Virtual Power Plant (VPP) participation: Storage systems monetize grid services like peak shaving, frequency regulation, and demand response.
Compared with legacy charging station, We slashes upfront investment and shortens payback. In the long run it becomes a diversified energy-revenue platform, compounding returns.
