Sunwoda's 15C LFP battery charges 10-97% in 9 minutes
Chinese battery maker Sunwoda has unveiled a new 15C LFP battery system capable of adding 100 km of range per minute.
Chinese battery manufacturer Sunwoda has introduced a new electric vehicle battery charging system that promises to add approximately 100 kilometers, or 62 miles, of range every single minute. The company presented data showing its 15C lithium iron phosphate (LFP) technology can charge a battery from 10% to 97% state of charge in just nine minutes under normal room temperature conditions.
Sunwoda made the announcement at a battery industry conference in Zaozhuang, Shandong. The presentation included specific charging speed claims for the new battery technology. According to the company, the system can achieve a 10% to 70% charge in only five minutes.
| Charging Interval | Claimed Time | Approx. Range Added |
|---|---|---|
| 10% to 70% SOC | 5 minutes | 100 km (62 miles) |
| 10% to 97% SOC | 9 minutes | 100 km (62 miles) |
Thermal management breakthrough
The reported achievement hinges on a significant advance in thermal management. Pushing enormous amounts of energy into a battery cell rapidly generates intense heat, which has historically been the primary barrier to ultra-fast charging. Sunwoda states its engineering effectively controls this heat, allowing for the record speeds at room temperature.
The thermal management system also performs in extreme cold. Sunwoda claims the battery can add 700 kilometers, or about 435 miles, of range in 15 minutes even when starting at a frigid -20 degrees Celsius. This dual-capability addresses two major consumer concerns about EVs: slow charging times and reduced performance in winter.
Battery longevity and warranty
Sunwoda directly challenges the common assumption that frequent fast charging degrades battery health. The company supplies batteries to several major Chinese automakers, including Geely, Dongfeng, and GAC. It states its batteries are designed to meet warranty requirements of 10 years or 300,000 kilometers with no limitation on the number of ultrafast charging sessions.
This claim, if validated in real-world use, could significantly alter the economics and practicality of EV ownership. It suggests drivers could regularly use the fastest available charging without fear of accelerating battery capacity loss.
A broader charging ecosystem
The battery technology is only one part of Sunwoda's vision. The company also unveiled plans for an open ecosystem supporting its flash charging capabilities. This system integrates solar power generation and battery energy storage with the ultra-fast charging hardware.
This move positions Sunwoda beyond being solely a battery cell supplier. The company is aiming to become a player in broader energy management, opening potential partnerships with energy companies and microgrid operators. The goal is to create a sustainable infrastructure that can support the high-power demands of its rapid charging technology.
Sunwoda's entry intensifies the global race to reduce EV charging times to match traditional refueling stops. The development arrives amid volatile global fuel prices.
