At the latest Auto Shanghai show, Sunwoda EVB showcased a series of innovations across multiple application areas, with a particular focus on advancements in vehicle electrification and low-altitude aviation.
In the hybrid electric vehicle (HEV) market, Sunwoda has surpassed 1.5 million battery installations. These batteries reportedly feature 60C fast-charging and 70C high-rate discharging capabilities, maintaining performance at temperatures as low as minus 30 degrees Celsius.
For range-extended and plug-in hybrid vehicles, the company introduced the Xinyingyao and Xinyingchi series, which support charging rates between 2C and 6C and deliver more than 500 kilometers of pure electric range. Designed for cold climates, these batteries can start at minus 35 degrees Celsius and retain over 90% of their range at minus 20 degrees Celsius. Both series have passed six rigorous safety evaluations, including cell-level high-temperature nail penetration and 12-meter drop tests, and come with a warranty covering ten years or 300,000 km.
In the pure electric vehicle category, Sunwoda presented the third-generation “flash charging battery,” capable of achieving a peak 6C charging rate, which is roughly equivalent to gaining approximately one kilometer of range per second. Featuring a low-temperature superconducting electrolyte and a 3D liquid cooling thermal management system, the battery maintains 90% charging efficiency even in environments as cold as minus 20 degrees Celsius.
Looking ahead, Sunwoda is preparing to launch next-generation ultrafast-charging batteries rated between 8C and 10C. These batteries are designed to reduce charging time from 10% to 80% state of charge (SOC) to just seven minutes, potentially making electric vehicle charging faster than conventional gasoline refueling.
To protect batteries during ultrafast charging, Sunwoda developed a lithium deposition boundary monitoring system. This system has been integrated into its high-energy-density lithium iron phosphate (LFP) batteries—which achieve 450 watt-hours per liter—as well as its ternary lithium variants that can support driving ranges up to 1,000 km.
The company’s two-pronged development strategy—pursuing advancements in both pure electric and hybrid technologies—has allowed it to accelerate R&D cycles while advancing range-extended EV infrastructure toward ultrafast charging capabilities.
In the commercial vehicle segment, Sunwoda revealed a battery system capable of 1.4 megawatts of charging power. This system enables recharging within 15 minutes and is projected to improve transportation efficiency by up to 400%. Designed for endurance, the battery supports more than 5,000 charge cycles and operational lifespans of up to eight years or two million km.
Sunwoda’s modular cell-to-pack (CTP) platform is compatible with approximately 85% of commercial vehicle models. Safety enhancements include a three-dimensional directional pressure relief system to prevent thermal runaway at the cell level. Alongside a smart operational network in 32 cities and a carbon footprint tracking system using battery passports, Sunwoda is constructing a comprehensive lifecycle management ecosystem encompassing ultrafast charging, battery swapping, and second-life applications.
Expanding into aerospace, Sunwoda introduced semi-solid-state batteries that achieve over 400 Wh per kilogram in energy density. According to the company, these batteries have passed extreme heat chamber and puncture resistance tests. The company also presented large-format cylindrical cells capable of 4C fast-charging while maintaining structural integrity under high-altitude conditions, supported by a three-dimensional thermal runaway prevention design.
Sunwoda also exhibited a compound-wing drone system powered by its aviation battery technologies. Looking ahead, the company plans to collaborate with partners to develop an integrated network combining ultrafast-charging stations, energy storage, and smart airspace management, aiming to move electric vertical takeoff and landing (eVTOL) aircraft and logistics drones toward commercial deployment.
Additionally, Sunwoda unveiled its second-generation intelligent cell technology, termed the 2.0 cell. Building on the Dianjing first-generation sensor, which introduced independent cell management and multidimensional data acquisition, the new 2.0 model incorporates advanced sensors that measure internal pressure, shell deformation, and electrochemical impedance alongside traditional battery management system (BMS) parameters such as current, voltage, and temperature.
In application, the 2.0 intelligent cell is expected to deliver four key benefits: enhanced predictive safety warnings, extended operational lifespan, improved health monitoring, and the introduction of a cell-level battery passport system. This “white-box” architecture enables real-time analysis of multidimensional safety parameters and ties them to Sunwoda’s proprietary BMS algorithms, enhancing transparency, control, and operational reliability across the entire battery lifecycle.
