Sunwoda Power unveils Xingchi Supercharge Battery 2.0 with 15C charging and sodium-ion cells

Sunwoda Power’s new battery line-up

Sunwoda Power has rolled out a broad range of new batteries, placing particular emphasis on a new generation of ultra-fast-charging packs, alongside sodium-ion batteries and battery systems with built-in artificial intelligence.

Xingchi Supercharge Battery 2.0 for passenger EVs

The main focus was on Xingchi Supercharge Battery 2.0

At the centre of the announcement was Xingchi Supercharge Battery 2.0 - a lithium iron phosphate (LFP) battery designed for passenger electric vehicles. It supports a peak charging rate of 15C, enabling charging from 5% to 95% in 9 minutes, or from 5% to 75% in 5.5 minutes.

The battery pack shown at the event uses 264 prismatic cells, delivering a capacity of more than 98.8 kWh at 844.8 V. Peak current reaches 1800 A, while service life exceeds 1500 cycles. Company executives stated that there are no restrictions on using ultra-fast charging during the warranty period.

Passenger-car and hybrid battery variants

Two additional passenger-car batteries were also introduced. One is a long-life version that claims no degradation in the first year and 10% degradation over 10 years. The other is a range-balanced battery for hybrid vehicles that uses large cylindrical cells; this hybrid-focused battery supports charging from 10% to 80% in 10 minutes.

For the hybrid segment, Sunwoda also presented battery packs ranging from 3 kWh to 7 kWh, built with cylindrical cells of 46 mm diameter. For instance, a 5 kWh pack provides 150 kW of output power and more than 15 km of electric-only range, while integrating DC and 12 V systems within a 414 V architecture.

Ultra-fast charging roadmap and commercial transport charging

Sunwoda said its fast-charging technology development began in 2019, progressing from 4C in 2022 to 6C in 2024, and then reaching 15C for lithium iron phosphate (LFP) and 8C for ternary lithium batteries in the latest iteration.

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

Energy storage: sodium-ion and LFP cells

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