Sunwoda Electric Vehicle Battery unveiled a 15C flash charging system in Zaozhuang on September 17 that charges an electric vehicle from 10 to 97 per cent in nine minutes.

The system matches the benchmark room-temperature charging speed established by market leader BYD. It also comes with a company commitment to deploy 10,000 megawatt charging stations by the end of 2027.

At room temperature, the battery charges from 10 to 70 per cent in five minutes. That adds 100 kilometres of driving range in 60 seconds. Total driving range exceeds 700 kilometres on a full charge.

Cold weather tests show the pack charges from 10 to 97 per cent in 15 minutes at minus 20 degrees Celsius. Sunwoda attached a warranty covering 10 years or 300,000 kilometres to non-commercial vehicles with unlimited ultrafast charging cycles, targeting buyer anxiety over high-current cell degradation.

Hardware diagnostics rely on proprietary cell sensors, an energy domain controller and a cloud monitoring engine. Sunwoda stated the platform identifies more than 20 separate failure modes between two and 10 days before a breakdown. Its detection rate reaches 99.77 per cent.

On the grid side, the company introduced an integrated platform that bundles solar generation, stationary battery storage, liquid-cooled charging posts and megawatt-scale dispensers. The multi-brand terminal design allows third-party automakers to access the high-voltage stalls under commercial sharing agreements.

China’s EV power race has shifted from laboratory power ratings to physical network footprint. BYD crossed its 10,000th flash charging station milestone on August 28. It maintains a target of 20,000 operational stations by the end of 2026.
