Three System Platforms Unveiled Alongside the New Ultra-Fast Charging Battery Matrix

• Xingchi System Platform: Adapts to A-B segment economical application scenarios.
• Xingyao System Platform: Adapts to extreme charging and high-end application scenarios.
• Xinghuan System Platform: Adapts to cylindrical PHEV/BEV applications.

The supporting cell solution employs the new-generation SkySupport Structure with high space utilization. Combined with positive/inverted bottom busbar layouts, it achieves high energy density + thermal-electric separation. At the system level, modular technologies such as foam adhesive potting, integrated liquid-cooled BDU (Battery Disconnect Unit), and direct plug-in slave controller FPC (Flexible Printed Circuit) are utilized. This endows SUNWODA Power's new-generation ultra-fast charging product matrix with characteristics of high integration, high safety, and high efficiency.

Leading Global Ultra-Fast Charging Battery Technology

As a global leader in ultra-fast charging battery technology, SUNWODA Power pioneered and mass-produced the industry's first 4C ultra-fast charging battery in September 2022. Through continuous technological iteration, by May 2025, the SUNWODA Power Flash Battery 4.0 has evolved to a 12C extreme charging version, compressing single replenishment time to the 5-minute level, ushering the industry into the "Era of Gasoline-Electric Replenishment Parity".

Among them, the core product of the Flash Battery 4.0 series – XinXingchi 2.0 Kiloampere Extreme Charging Edition – is the world's first ultra-fast charging battery product to increase charging current to 1400A. When paired with a vehicle-side 1000V high-voltage system platform, it can support up to 1.4MW flash charging, delivering a brand-new replenishment experience: 150km+ in 1 minute of extreme charging, 450km replenishment in 5 minutes, achieving gasoline-level speed – charge and go.

Deep Technological Innovation

Products that directly address user delight points stem from deep innovation:

• Hot-to-Cold Direct Conduction & Multi-Sided Sandwich Cooling Design: Cooling area increased by ~50%, enabling timely heat dissipation for MW-level fast charging, ensuring safe and worry-free operation.
• Multi-level Technology Integration: Aerospace-grade thermal insulation technology, low-temperature resistant high-energy LFP cathode technology, and low-temperature superconductor electrolyte technology ensure worry-free low-temperature travel: retains over 90% energy capacity at -20°C, and remains operational even in extreme cold of -40°C.
• Ultra-Fast Charging Long-Life Anode Technology: Regional activity regulation design combined with high-temperature resistant SEI film reconstruction technology solves the industry challenge of ultra-high current charging damaging battery lifespan.

XinXingchi 2.0 Long-Range Edition

Another core product in the series, the XinXingchi 2.0 Long-Range Edition, benefits from ultra-high voltage dense cathode technology, second-generation composite thick electrode technology, and the space-maximizing "SkySupport" structure. This propels LFP ultra-fast charging cell energy density to break industry records again, exceeding 200Wh/kg. Combined with the Xingchi system architecture boasting over 80% mass integration rate, it achieves both 6C ultra-fast charging and an 800km+ ultra-long range. This realizes a phosphate iron lithium (LFP) alternative to ultra-fast charging NCM ternary batteries, reducing costs by over 10%, providing tremendous impetus for increasing the market penetration of ultra-fast charging technology.

XinXingyao 2.0 Kiloampere Extreme Charging Edition (High-End Market)

Positioned for the high-end market, the XinXingyao 2.0 Kiloampere Extreme Charging Edition not only achieves an ultra-long range of 1000km+, but also supports 8C charging with a charging current exceeding 1000A. It replenishes 700km in just 8 minutes of charging, truly delivering unlimited range and charging freedom.

Underpinning this is SUNWODA Power's self-designed new-generation porous silicon-carbon anode: Through nano-buffering network design, it improves silicon interface stability, achieving low lithium consumption and long lifespan. This results in multiple advantages for the cell: 260+ Wh/kg high energy density, long life, and ultra-fast charging. Matched with the Xingyao system architecture, it features a new-generation 3D liquid cooling technology with active spray protection. Upon over-temperature alarm, powerful cooling is activated; during thermal runaway, coolant actively sprays for cooling. Thermal-electric separation ensures passenger cabin safety. It possesses ultra-high safety redundancy with multi-point high-temperature triggering preventing thermal runaway.

Dr. He Xuan, General Manager of SUNWODA Power's Cell Product Line, stated: "The Flash Battery 4.0 Kiloampere Extreme Charging product is not merely an iteration of ultra-fast charging technology, but a comprehensive technological innovation and reconstruction spanning multiple levels (material/cell/pack), multiple dimensions (thermal/mechanical/electrical), multiple aspects (safety/reliability), and the entire system."

Enhanced PHEV Batteries Leveraging Flash Charging Technology

The newly launched XinXingyao/XinXingchi PHEV Batteries fully leverage the benefits of flash charging technology, with comprehensively upgraded fast-charging capabilities. 800V+ system models adopt ultra-fast charging solutions transplanted from BEVs, while 400V models are equipped with upgraded 4-6C solutions offering enhanced energy density and charging capability. Simultaneously featuring 200-400km pure electric range and wide temperature operating characteristics, they deliver both long range and ultra-fast charging, doubling user value experience.

6C Fast Charging 190Wh/kg LFP Cylindrical PHEV Battery (Small Battery Market)

Additionally, for the small battery power and two-wheeler market (A0/A00 BEV, A-class PHEV), SUNWODA Power launched the world's first 6C fast-charging 190Wh/kg LFP cylindrical PHEV battery. SUNWODA Power cylindrical batteries offer four major advantages:

• Versatile Orientation: "Horizontal" or "Vertical" placement enables worry-free multi-scenario compatibility, adapting to 50-150km A00-A class models.
• High Energy Density: Direct connection collector disk with same-side current collection, increasing radial space utilization by ~3% year-over-year.
• Extremely Low Internal Resistance: Self-innovated intermittent full tab + concentric circle welding design enables coaxial electron transport, shortening path by 20%, reducing heat generation by 5℃.
• Long-Life Innovative Design: Uniform core stress growth throughout the entire lifecycle with no collapse deformation, easily achieving a 10-year / 300,000 km warranty.

As the saying goes, "Square has its shortcomings, round has its strengths." Deeply exploring different application scenarios allows SUNWODA Power to precisely match the optimal solution for both prismatic and cylindrical cells. In small-battery BEV and PHEV models, cylindrical batteries, with their low cost and high flexible compatibility, are better suited for application.

HEV Products: Superior to Gasoline Vehicles

Compared to gasoline models, SUNWODA Power's HEV products possess the following characteristics: Ultra-low fuel consumption, low purchase and usage cost; Superb electric drive, comparable to pure electric driving experience; Unaffected by extreme cold or heat, with no range discount and no charging anxiety. They exhibit strong competitiveness in regions with underdeveloped charging infrastructure like Europe, America, Southeast Asia, and South America.

SUNWODA Power's new-generation HEV products not only feature ultra-high power (80kW discharge), ultra-long life (100,000 cycles), ultra-low operating temperature (-40°C), and ultra-safety & reliability, but also achieve ultra-low TCO (Total Cost of Ownership), with a three-year comprehensive cost lower than gasoline vehicles. The company has achieved the number one position in domestic hybrid lithium battery shipments for four consecutive years, becoming the industry leader in high-power HEV products, and earning the deep trust of over one million global vehicle owners.

Driving the Industry Forward

At the critical juncture where China's new energy vehicle penetration rate has continuously exceeded 50%, the ultra-fast charging power battery matrix product technology released by SUNWODA Power not only realizes charging speed-up for full-scenario vehicle applications but will also further promote "technology democratization" of ultra-fast charging from high-end flagship models to mass-market vehicles. In the future, SUNWODA Power will continuously strive to lead the innovation of ultra-fast charging power battery technology, contributing solid strength to the development of the new energy vehicle industry.
