Sunwoda EV Battery Unveils 15C System, Targets 10,000 Chargers

Sunwoda Unveils 15C Flash Charging Battery System

Sunwoda Electric Vehicle Battery Co Ltd has introduced a 15C smart flash charging battery system as competition over ultrafast electric vehicle charging accelerates in China. The battery maker announced the system and its charging-network plan on September 17, following its debut at a battery industry conference held September 16-17 in Zaozhuang, Shandong province. Sunwoda said the system can support a driving range of more than 700 kilometers while combining high-rate charging with smart monitoring functions. The company also plans to expand an associated flash charging ecosystem, targeting 10,000 megawatt charging stations by the end of 2027.

Sunwoda's 15C Battery Targets Faster Charging

Data presented by Sunwoda at the conference showed that the new battery system can charge from 10% to 70% in five minutes and from 10% to 97% in nine minutes at room temperature. A one-minute charge can add 100 kilometers of range, according to the company's presentation. The room-temperature charging times for both intervals match figures that BYD announced when it unveiled its second-generation Blade Battery in March. At minus 20°C, Sunwoda said the system requires 15 minutes to charge from 10% to 97%. The company also stated that the system can meet warranty requirements of 10 years or 300,000 kilometers.

Battery Durability and Smart Monitoring

Sunwoda is also positioning the battery around durability and intelligent monitoring rather than charging speed alone. The company said the system has no limit on ultrafast charging sessions for vehicles that are not used commercially, addressing concerns that repeated high-rate charging could reduce battery life. The architecture combines smart battery cells 3.0, an energy domain controller, and an AI cloud-control platform. Sunwoda said these components improve battery monitoring and early fault detection. According to the company's statement, the system can provide warnings for more than 20 types of faults between two and 10 days in advance, with an accuracy rate of 99.77%.

Sunwoda Expands Into Megawatt Charging Infrastructure

Alongside the battery system, Sunwoda unveiled an open ecosystem platform combining solar power, energy storage, and flash charging. The platform integrates flash charging EV batteries, energy storage systems, megawatt charging units, high-power liquid-cooled charging terminals, and the company's AI cloud-control platform. It is designed to support vehicles from multiple brands and different partnership models, extending Sunwoda's offering beyond battery supply into charging infrastructure. The company expects its flash charging ecosystem to include 10,000 megawatt charging stations by the end of 2027. However, its announcement did not specify station locations, investment plans, initial vehicle models, or a mass-production timetable.

China's Flash Charging Competition Expands

The competitive focus in China's flash charging market is increasingly extending from individual technology launches toward charging-network deployment. BYD said it completed its 10,000th flash charging station in China on August 28 and reiterated a target of 20,000 stations by the end of 2026. Other automakers and battery developers are also advancing high-rate charging. Hongqi said testing in July showed that a battery jointly developed with China Automotive New Energy Battery Technology could charge from 10% to 70% in three minutes and 41 seconds at 25°C. The brand did not provide a mass-production timetable at that time, leaving deployment scale and commercial availability as important factors in the market's next stage.

Megawatt Charging Developments From Chinese Automakers

Dongfeng introduced a prototype of its independently developed ultrafast charger on July 29, with peak output of 1,500 kW per charging connector, matching the output of BYD's new flash charger unveiled in March. Xpeng also announced on September 15 that its first X-Energy megawatt charging station had begun operating in Hong Kong. Jointly built with local charging provider Halo, the station is open to drivers of all vehicle brands. It has a peak output of 1 megawatt and includes 400 kWh of energy storage. The station's stated output represents its capacity, while actual vehicle charging power remains dependent on the vehicle's battery and charging capabilities.

Industry Impact & Outlook

Sunwoda's announcement adds another large-scale charging-network target to China's rapidly developing ultrafast charging landscape, increasing the importance of both battery performance and infrastructure availability. The combination of a 15C battery, megawatt charging hardware, energy storage, and AI-based monitoring indicates that competition is expanding toward integrated charging ecosystems rather than isolated battery specifications. The stated 10,000-station target could broaden access to high-power charging if deployment plans and commercial vehicle compatibility are subsequently disclosed. For automakers, charging providers, and battery suppliers, the key next steps will include vehicle integration, mass-production timing, station locations, investment commitments, and evidence that high-rate charging performance can be delivered consistently under different operating conditions.

Frequently Asked Questions

What charging performance does Sunwoda's new battery system offer?
The system can charge from 10% to 70% in five minutes and from 10% to 97% in nine minutes at room temperature, while a one-minute charge can add 100 kilometers of range. Sunwoda said the battery can support more than 700 kilometers of driving range and requires 15 minutes to reach 97% from 10% at minus 20°C. The company also stated that the system meets warranty requirements of 10 years or 300,000 kilometers, with no limit on ultrafast charging sessions for noncommercial vehicles.

How many megawatt charging stations does Sunwoda plan to deploy?
Sunwoda expects its flash charging ecosystem to include 10,000 megawatt charging stations by the end of 2027. The company has not disclosed the planned locations, investment requirements, initial vehicle models, or mass-production timetable associated with the network. Its ecosystem platform combines flash charging batteries, energy storage, megawatt charging units, liquid-cooled charging terminals, solar power, and an AI cloud-control platform. The stated target therefore represents an infrastructure expansion plan, while the details needed to assess its deployment schedule remain undisclosed.
