Sunwoda 15C LFP battery pack took centre stage at the company’s April 16 technology day in Beijing. The new battery targets passenger EVs that need much faster charging without sacrificing useful capacity. Moreover, Sunwoda used the event to show how its battery roadmap now spans ultra-fast charging, sodium-ion products, hybrid packs, commercial vehicle systems, and AI-based battery management.
The headline product is the Xingchi Supercharge Battery 2.0. Sunwoda designed this lithium-iron phosphate battery pack for 15C charging. As a result, the pack can charge from 5% to 95% state of charge in just 9 minutes. It can also move from 5% to 75% in 5.5 minutes. Those figures place charging speed at the centre of Sunwoda’s latest strategy.
Sunwoda 15C LFP battery pack specifications
Sunwoda built the demonstrated pack with 264 prismatic cells. The system delivers more than 98.8 kWh of capacity and runs at 844.8 V. In addition, the pack supports a maximum current of 1,800 A. Sunwoda said cycle life exceeds 1,500 cycles. Company executives also stated that owners can use ultra-fast charging during the warranty period without usage limits.
These figures matter because they show a clear push toward practical high-power charging. For many EV buyers, charging time now matters as much as energy density or pack cost. Therefore, Sunwoda is positioning this pack around real-world convenience and time savings.
How the Sunwoda 15C LFP battery pack fits its fast-charging roadmap
Sunwoda said it started its fast-charging development work in 2019. Since then, it has increased charging performance in steady steps. The company moved from 4C in 2022 to 6C in 2024. Now, it has reached 15C for LFP batteries and 8C for ternary lithium batteries. This timeline shows a focused and deliberate development path.
At the same event, Sunwoda introduced two more passenger vehicle batteries. First, it showed a long-life version that claims zero degradation in the first year. It also targets only 10% degradation over 10 years. Second, it presented a range-balanced battery for hybrid vehicles that uses large cylindrical cells. That hybrid pack can charge from 10% to 80% in 10 minutes.
Hybrid and commercial battery systems
Sunwoda also expanded the discussion beyond passenger EVs. In the hybrid segment, the company introduced battery packs from 3 kWh to 7 kWh using 46 mm cylindrical cells. For example, a 5 kWh pack delivers 150 kW output and supports more than 15 km of electric range. It also integrates DC-DC and 12V systems within a 414 V architecture.
For commercial vehicles, Sunwoda presented a dual-gun charging system with peak charging power of 1.44 MW. That figure suggests the company wants to address faster turnaround times in logistics and heavy-use transport applications as well.
Sunwoda 15C LFP battery pack and sodium battery strategy
Alongside the Sunwoda 15C LFP battery pack, the company outlined its sodium battery strategy. In energy storage, Sunwoda launched several sodium-ion and LFP battery cells. According to Xu Zhongling, president of the company’s Central Research Institute, sodium batteries can deliver more than 20,000 cycles at room temperature. They can also exceed 10,000 cycles at high temperatures.
Sunwoda emphasized three main strengths of sodium batteries. First, sodium draws on abundant raw materials. Second, the chemistry supports lower lifecycle cost thanks to strong durability. Third, it offers favorable safety characteristics. Because of these traits, Sunwoda sees sodium batteries as a strong fit for energy storage, low-voltage vehicle systems, and accessible vehicle applications.
This strategy complements the company’s LFP push rather than replacing it. On one hand, the 15C LFP pack addresses ultra-fast charging for passenger EVs. On the other hand, sodium batteries support durable and cost-conscious use cases. Together, these product lines give Sunwoda a broader market reach.
AI strategy supports the Sunwoda 15C LFP battery pack roadmap
Sunwoda also introduced its “AI+ battery” strategy. The company said this approach will support data-driven research and development, multi-scenario deployment, and ecosystem collaboration. In practical terms, Sunwoda wants to apply AI across battery development, manufacturing, and lifecycle management.
This matters because battery competition now depends on more than chemistry alone. Companies also need better design tools, production control, and operational data. Therefore, AI can help improve battery consistency, optimize charging behavior, and support predictive lifecycle management.
Market context for Sunwoda battery business
According to China EV DataTracker, Sunwoda installed 1.4 GWh of EV batteries in March 2026. That gave the company a 2.5% market share. The figure was down from 2.8% in January, yet it remained broadly stable year on year. Sunwoda’s battery mix also remains heavily focused on LFP chemistry, while ternary lithium accounts for only a small share.
Overall, Sunwoda’s latest announcement shows how battery competition is evolving. Charging speed, lifecycle durability, and application-specific design now shape product strategy more directly. As a result, the Sunwoda 15C LFP battery pack stands out not only for its 9-minute recharge claim, but also for how it fits into a wider battery roadmap that includes hybrids, commercial systems, sodium-ion cells, and AI-enabled management.
