Sunwoda Claims Nine-Minute EV Battery Charging

Sunwoda’s 15C system was presented at a battery industry conference in Zaozhuang, Shandong province, China, placing the announcement within the country’s broader competition to accelerate EV charging speeds.
The claimed charging performance would substantially exceed benchmarks cited for current fast-charging systems: Tesla’s V3 and V4 Superchargers can deliver up to 250 kW and add about 200 miles of range in roughly 15 minutes, while BMW and Mercedes-Benz systems generally require around 22 to 35 minutes for comparable charging.
Sunwoda branded its solar-plus-storage-plus-charging platform the “Omnipotent · Boundless” PV+ESS flash-charging open ecosystem, indicating that the company is developing infrastructure alongside the battery technology rather than focusing only on cells.
The company’s durability claim is intended to address a common concern that repeated high-power charging accelerates battery degradation; Sunwoda presented the warranty and lack of a separate fast-charging-session cap as evidence that ultra-fast charging need not automatically shorten battery life.
Chinese battery maker Sunwoda has unveiled a new lithium-iron-phosphate battery technology that it claims can charge an electric vehicle from nearly empty to 70% in just five minutes, according to announcements at a battery industry conference in Shandong province. Sunwoda says its 15C battery system reaches 97% capacity in nine minutes and can add roughly 100 kilometers of range per minute at room temperature, with similar performance even in extreme cold.
If verified, the breakthrough would significantly outpace current industry standards. Tesla's latest Superchargers add about 200 miles of range in roughly 15 minutes, while BMW and Mercedes-Benz systems typically require 22 to 35 minutes for comparable charging. Sunwoda also claims its battery supports a 10-year, 300,000-kilometer warranty without limiting ultra-fast charging sessions, addressing concerns that rapid charging degrades battery life.
Sunwoda's announcement reflects intense competition among Chinese automakers and battery suppliers to claim the fastest charging crown. Geely Auto Group recently introduced its own system claiming four-minute charging speeds using AI-powered energy management. BYD, China's dominant EV maker, has also pushed aggressive fast-charging targets. These competing claims signal that China is positioning itself as the leader in ultra-rapid EV refueling technology.
Unlike competitors focused on room-temperature speeds, Sunwoda claims its 15C technology maintains ultra-fast charging even at minus 20 degrees Celsius, delivering about 700 kilometers of range after 15 minutes in freezing conditions. This capability matters in northern climates where cold severely reduces battery performance. The company says its thermal-management system keeps the battery stable during extreme high-power charging without compromising longevity or safety.
Sunwoda is not simply selling batteries—it is constructing infrastructure around them. The company branded its charging platform the "Omnipotent · Boundless" PV+ESS ecosystem, combining solar panels, energy storage, and fast-charging stations. Sunwoda targets 10,000 megawatt-scale flash-charging stations by the end of 2027. The company already supplies batteries to Geely, Dongfeng, and GAC, giving it leverage to deploy this integrated system across multiple vehicle makers.
While Sunwoda's claims are striking, they remain unverified by independent labs or real-world field tests. Battery makers routinely announce lab results that differ from consumer experience. The company's 10-year, 300,000-kilometer warranty without fast-charging caps is designed to show confidence, but only long-term use by thousands of drivers will prove whether ultra-rapid charging truly avoids accelerated degradation. Industry experts say skepticism is warranted until third-party validation arrives.
