At its April 16 technology day in Beijing, Sunwoda Power unveiled a comprehensive battery product roadmap spanning passenger vehicles, commercial transport and energy storage. The highlight is the “Xingchi Supercharge Battery 2.0,” a lithium-iron phosphate (LFP) pack engineered for 15C peak charging. This design enables a state-of-charge increase from 5% to 95% in nine minutes or from 5% to 75% in 5.5 minutes. The demonstration unit contains 264 prismatic cells delivering over 98.8 kWh capacity at an operating voltage of 844.8 V, with a maximum current of 1,800 A and a cycle life beyond 1,500 cycles. Sunwoda confirmed that ultra-fast charging performance is fully covered under its warranty.
Two additional passenger EV battery variants were introduced. A long-life LFP version promises zero capacity loss in the first year and no more than 10% loss over ten years. The range-balanced pack, aimed at hybrid applications, uses large cylindrical cells and can recharge from 10% to 80% in ten minutes.
Building on its fast-charging expertise, which advanced from 4C-capable packs in 2022 to 6C in 2024, the company has now reached 15C for LFP and 8C for ternary lithium chemistries. For commercial vehicles, Sunwoda demonstrated a dual-gun charging system delivering up to 1.44 MW of peak power.
In the hybrid segment, new battery modules sized between 3 kWh and 7 kWh make use of 46 mm cylindrical cells. A representative 5 kWh pack offers a 150 kW power output and over 15 km of electric range, integrating DC-DC conversion and a 12 V subsystem within a 414 V architecture.
Sunwoda also expanded its sodium-ion and LFP cell offerings for energy storage. According to Xu Zhongling, president of the company’s Central Research Institute, sodium-ion cells achieve more than 20,000 cycles at room temperature and over 10,000 cycles at elevated temperatures. He cited three advantages—ample raw materials, lower lifecycle costs and enhanced safety—while noting that lower energy density compared to lithium-based cells positions sodium batteries for low-voltage systems and entry-level models.
The company’s “AI+ battery” strategy was outlined as a data-driven framework for R&D, manufacturing and lifecycle management, with an ecosystem-focused deployment. Sunwoda also continues parallel development of solid-state prototypes targeting 400 Wh/kg energy density, 1,200 cycles and up to 1,000 km range. Market data show Sunwoda installed 1.4 GWh of EV batteries in March 2026, holding a 2.5% share, with its product mix predominantly LFP chemistry. These announcements underscore a broader industry shift toward ultra-fast charging, durability and application-specific optimization across EVs and storage solutions.
