- Sunwoda unveiled a new 15C LFP EV battery that charges from 10% to 97% state of charge in 9 minutes at room temperature, adding roughly 60 miles of range per minute of charging.
- The company presented the technology at a battery industry conference in Zaozhuang, Shandong, claiming the pack reaches 10-70% SOC in just 5 minutes.
- Sunwoda called thermal management the real breakthrough — sustaining extreme energy flows into a battery in minutes without overheating at room temperature.
- The same battery charges from 10-97% SOC in 15 minutes at -20°C, delivering 700 km (~435 miles) of range in a deep freeze.
- Sunwoda said the cells can meet a 10-year or 300,000 km warranty with no cap on ultrafast charging sessions, directly challenging the notion that fast charging shortens battery life.
- The company also announced an open ecosystem combining solar power, battery energy storage, and ultra-fast chargers — positioning Sunwoda to partner with energy companies and microgrids, not just automakers.
Why it matters: Sunwoda already supplies Geely, Dongfeng, and GAC, so a production-ready sub-10-minute charge that also works at -20°C erases one of the last practical edges gas cars hold over EVs in cold-climate markets and puts pressure on global rivals whose packs charge far slower.
