Sunwoda unveils Xingchi Supercharge Battery 2.0 and new battery systems

Xingchi Supercharge Battery 2.0 takes centre stage

Sunwoda Power has unveiled a range of new batteries, with particular emphasis on its latest generation of ultra-fast-charging products, sodium-ion batteries and battery systems incorporating artificial intelligence.

The presentation focused on the Xingchi Supercharge Battery 2.0, a lithium iron phosphate (LFP) battery developed for passenger electric vehicles. It supports a peak charging rate of 15C, enabling a charge from 5% to 95% in 9 minutes, or from 5% to 75% in 5.5 minutes.

The battery pack displayed at the event uses 264 prismatic cells and provides capacity exceeding 98.8 kWh at 844.8 V. Peak current reaches 1,800 A, while service life is more than 1,500 cycles. Company executives said that ultra-fast charging is not restricted during the warranty period.

Passenger-car batteries and charging development

Two further passenger-vehicle batteries were also introduced. One is a long-life version claimed to have no degradation during its first year and 10% degradation over 10 years. The other is a range-balanced battery for hybrid vehicles, built around large cylindrical cells and capable of charging from 10% to 80% in 10 minutes.

Sunwoda said its fast-charging technology programme began in 2019. The technology progressed from 4C in 2022 to 6C in 2024, before reaching 15C for lithium iron phosphate (LFP) batteries and 8C for ternary lithium batteries in the latest generation.

For commercial vehicles, the company presented a dual-charger system with peak charging power of 1.44 MW.

Hybrid and energy-storage battery systems

In the hybrid-vehicle segment, Sunwoda introduced battery packs ranging from 3 kWh to 7 kWh, using cylindrical cells with a diameter of 46 mm. For example, the 5 kWh battery delivers 150 kW of output and offers more than 15 km of electric-only range, while integrating DC and 12 V systems into a 414 V architecture.

For energy storage, Sunwoda launched several sodium-ion and lithium iron phosphate battery-cell models. According to Xu Zhongling, President of the company’s Central Research Institute, sodium batteries can withstand more than 20,000 cycles at room temperature and over 10,000 cycles at high temperatures.
