China’s State Science and Technology Progress Awards have spotlighted major advances in EV battery and chassis technology, with leading automakers BYD, Geely, and Changan recognized for their collaborative engineering efforts. The awards underscore how shared research is shaping the next generation of high-safety, ultra-fast charging electric vehicles.
State Awards Recognize Collaborative Battery Breakthroughs
Power battery architectures and ultra-fast charging systems received the highest honors at this year’s State Science and Technology Progress Awards. The recognized projects were the result of joint research by Changan Automobile, China Automotive Engineering Research Institute, Calb, and BYD. Their work established standard protocols for battery safety and longevity, enabling cells to handle high-amperage charging while resisting internal corrosion.
A key focus was on thermal management: the awarded systems maintain internal cell temperatures below the strict 65°C threshold during rapid charging. Vehicle software now monitors battery telemetry multiple times per second, preventing dangerous hot spots and extending battery life. This approach standardizes predictive algorithms and thermal management rules, while allowing each automaker to retain proprietary cell designs and chemistries.
Distinct Battery Designs, Unified Safety Standards
While the software and safety protocols are shared, physical battery designs remain unique. BYD uses long, rectangular Lithium Iron Phosphate cells as structural elements, while Changan focuses on high-stability cells with a 5,000-cycle durability target. Changan confirmed that its Deepal brand passenger vehicles use the award-winning Golden Shield battery technology.
Geely’s short-blade cell architecture achieved a certified peak input of 1,093 kW during state testing. The joint engineering push has already enabled around 100,000 flash-charging vehicles to operate on Chinese roads, demonstrating the real-world impact of these advances.
Intelligent Chassis and Advanced Manufacturing
Separate state honors went to intelligent electric chassis systems, co-developed by Tsinghua University with BYD, Geely, and Great Wall Motors. These chassis use electromechanical braking with top safety ratings, ensuring vehicle control even if digital systems fail. Advanced regenerative braking algorithms can boost city driving range by up to 15%.
Manufacturing innovations were also recognized. Real-time closed-loop monitoring for resistance welding lines now ensures uniform bond strength in steel and aluminum panels, reducing defects and improving structural integrity. These advances support the rapid rollout of high-power charging infrastructure, with new stations capable of delivering up to 1,500 kW of peak output.
Competitor Comparison
The technologies recognized by the state awards position BYD, Geely, and Changan alongside other major Chinese OEMs, who collectively hold over 65% of the domestic market. These advances are particularly relevant as new energy vehicle (NEV) shipments in China rose 36.7% year-on-year in 2025, outpacing global trends and reinforcing the country’s leadership in EV innovation.
Historical Context
In 2023, global vehicle sales reached 34.4 million units, a 9.4% increase year-on-year. Chinese automakers have continued this momentum into 2026, with a 4.5% year-on-year growth rate and a dominant share of the NEV market. The rapid deployment of shared battery and chassis technologies is a key factor in sustaining this growth.
Why this matters
The recognition of shared battery and chassis technologies at the state level highlights a shift toward industry-wide safety and performance standards in China’s EV sector. By standardizing critical software and safety protocols while allowing for hardware differentiation, Chinese automakers can accelerate innovation and scale production without compromising on safety.
These advances also enable faster charging, longer battery life, and improved driving range, directly benefiting consumers and supporting the expansion of high-power charging infrastructure nationwide.
What this means for buyers
For EV buyers in China and globally, these engineering breakthroughs mean access to safer, faster-charging, and more durable electric vehicles. As more automakers adopt these shared standards, expect to see improvements in charging convenience and battery longevity across a wider range of models.
Buyers should look for vehicles featuring the latest battery management and chassis technologies, as these are likely to offer better real-world performance and long-term reliability.
