Introduction: The New National Standard is Released, Upgrading the Safety of Power Batteries
On March 28, 2025, the Ministry of Industry and Information Technology of China officially issued the "Safety Requirements for Power Batteries for Electric Vehicles" (GB 38031 - 2025). This standard sets higher requirements for the thermal runaway protection, fast - charge cycle life, and mechanical safety of power batteries, and will come into effect on July 1, 2026. This standard is not only fully aligned with international regulations but also marks a new "safety - driven" stage for China's power battery industry.
I. The Core Challenge of the New National Standard: How to Implement Safety Requirements?
The new national standard adds several stringent tests, including:
· Thermal Diffusion Test: After the battery experiences thermal runaway, it should neither catch fire nor explode and issue a 5 - minute advance warning.
· Fast - Charge Cycle Test: After 300 fast - charge cycles, it must pass the external short - circuit safety assessment.
· Bottom Impact Test: Simulates the battery's protection ability in extreme scenarios.
As a leading enterprise in Battery Formation and capacity testing equipment, Shengchuang Intelligent Technology (Guangdong) Co., Ltd. is well aware that the origin of battery safety lies in manufacturing, and the formation and capacity testing process is the first line of defense to ensure safety!
These tests seemingly focus on "result acceptance," but in fact, they put forward higher requirements for the battery manufacturing process. If there are defects in the formation and capacity testing process, the battery's consistency and stability will be insufficient, directly leading to test failures.
II. Formation and Capacity Testing: The "Invisible Guardians" of Battery Safety
Formation and capacity testing is the core process of lithium - battery manufacturing, directly affecting the battery's consistency, lifespan, and safety. Shengchuang Intelligent Technology helps customers meet the new national standard from the source through two technical approaches:
1.Formation Process: Building a Solid SEI Film Defense Line to Resist Thermal Runaway Risks
· Technical Core: By precisely controlling the current, voltage, and temperature, a uniform and stable SEI film (Solid Electrolyte Interface film) is formed, greatly enhancing the battery's resistance to thermal runaway.
· Correlation with the National Standard: The quality of the SEI film directly determines the battery's performance in the thermal diffusion test, avoiding chain reactions caused by local defects.
2.Capacity Grading and Screening: High - Precision Classification to Ensure Battery Consistency
· Technical Core: Adopts a current and voltage detection accuracy of 0.01%, screening battery cells with highly consistent capacity and internal resistance.
· Correlation with the National Standard: Battery packs with insufficient consistency are prone to single - cell overload during the fast - charge cycle test, resulting in short - circuit failure after cycling. In contrast, battery packs with high consistency can significantly reduce this risk.
III. Shengchuang Intelligent Technology: Empowering the New National Standard with High - Quality Equipment
Facing the stringent requirements of the new national standard, Shengchuang Intelligent Technology has launched the fourth - generation integrated formation and capacity testing system, which has become the industry's top choice with three advantages:
· Ultra - High - Precision Control: The current and voltage accuracy reaches ±(0.5‰ reading + 0.5‰ full - scale), ensuring that the parameters of each battery meet the standards strictly.
· Intelligent Software: Optimizes the charge - discharge curve in real - time and dynamically adapts to the characteristics of different battery cells.
· Modular Design: Supports customers' customized requirements and flexibly responds to diversified battery models.
Case Verification: After a leading battery enterprise adopted Shengchuang's equipment, the capacity grading consistency increased by 30%, and the fast - charge cycle test pass rate increased to 99.8%, far exceeding the requirements of the new national standard!
IV. Industry Outlook: Safety Standards Drive Process Upgrades, and Shengchuang Leads Technological Transformations
With the implementation of the new national standard, the power battery industry will accelerate the elimination of low - end production capacity. High - precision, intelligent, and customized formation and capacity testing equipment has become a rigid demand. Shengchuang Intelligent Technology will continue to deeply cultivate technological innovation and provide customers with:
· Full - Process Solutions: Provide technical support throughout the process, from process design to equipment delivery.
· Global Compliance Support: The equipment parameters are compatible with international standards such as UN R100 and IEC, helping enterprises seize overseas markets.
