On March 28, 2025, the State Administration of market supervision and administration and the National Standardization Management Committee officially released a new version of the mandatory national standard-GB 38031-2025. This standard is an important specification for the power battery industry, involving many aspects of product design, production, testing and use, to ensure the safety of power batteries, performance and its application in electric vehicles and other fields are of great significance. This article will explain the core content of this standard in detail and analyze its impact on the industry.

I. Standard background

as the core component of electric vehicles and energy storage devices, the performance and safety of power batteries are directly related to the safety of users' lives and property. In recent years, with the rapid development of electric vehicle industry, the market's requirements for power batteries have been continuously improved. Under this background, the original battery standards have become insufficient in terms of safety and performance evaluation, and new mandatory national standards are urgently needed to ensure the healthy development of the industry.

GB 38031-2025 standard covers many key fields of power batteries, including battery structure design, safety requirements, performance testing, cycle life evaluation, disposal management of waste batteries, etc.

II. Interpretation of core content

1. Security requirements

in the standard, higher requirements are put forward for the safety of power batteries. Battery products must pass multiple safety tests, including:

• collisionTest: the battery needs to go through intersection detection under certain conditions to ensure the stability of the structure.
• Short circuit test: it is required to evaluate the reaction of the battery by simulating short circuit scenarios, so as to prevent dangerous situations during use.
• High temperature and humidity test: in extreme environment, the battery should maintain good safety performance. The standard stipulates that the battery should be evaluated for a long time under the condition of high temperature and high humidity.

The above tests ensure the safety of the battery in various environments and stress conditions, and reduce the potential safety hazards caused by battery failure.

2. Performance evaluation

the standard clearly stipulates the performance evaluation of power batteries, including:

• energy density and power density: according to the type of battery, the minimum energy density and power density requirements are specified to improve the performance of the battery and meet the needs of electric vehicles for endurance and acceleration.
• Cycle Life: The standard specifies the test method of cycle life and evaluates the performance attenuation of the battery during long-term charging and discharging. This is an important indicator to judge the durability and economy of the battery.

In the evaluation process, unified testing methods and standard parameters are applied to ensure that the products of various manufacturers can reach the corresponding industry standards and increase the transparency of the market.

the GB 3803-2025 standard also explains the structural design of power batteries in detail, emphasizing:

• module and battery pack design: it is required that the design should take into account the heat dissipation performance, structural strength and electrical safety to ensure the stability of the battery under high load working conditions.
• Protective measures: both the inside and outside of the battery need to take protective measures to prevent the interference of external objects and prevent fire accidents caused by short circuit inside the battery.

Through the strict specification of the design, the standard aims to ensure the overall safety and reliability of the battery, thus improving the confidence of users when using it.

4. Waste battery management

with the rapid popularization of electric vehicles, the management of abandoned power batteries is becoming more and more important. GB 38031-2025 emphasizes:

• responsibility for recycling and reuse: manufacturers should assume the responsibility of recycling and reusing waste batteries, and must establish a perfect recycling mechanism for waste batteries to reduce environmental pollution.
• Processing Standard: for the disposal of waste batteries, the standard specifies specific methods and procedures to ensure that the impact on the environment and human health is minimized.

III. Implementation and compliance

the production enterprise is responsible for the implementation of GB 3803-2025 and needs to make preparations, including:

• equipment and technology updates: enterprises need to evaluate whether the existing production equipment and technology meet the standard requirements and make improvements as needed.
• Establishment of quality management system: enterprises need to establish or optimize the quality management system to ensure that the new standards are strictly followed in product design, manufacturing and after-sales.
• Staff training: train relevant practitioners in standard content and improve their recognize and appreciate of the new standard to ensure strict implementation in operation and management.

Following these implementation steps, enterprises can not only reduce compliance risks, but also enhance market competitiveness.

IV. Industry impact analysis

the implementation of GB 3803-2025 will power Battery the industry has a profound impact:

• upgrade productsQuality: stricter safety performance testing will promote the overall product quality of the industry and enable consumers to purchase safer and more efficient power batteries.
• Promote industry standardization: unified standards will form effective norms for all manufacturers, reduce the degree of market confusion and enhance industry transparency.
• Strengthen innovation ability: on the premise of meeting the new standards, enterprises will pay more attention to technological innovation to enhance the competitive advantage of products.

In general, the release and implementation of GB 3803-2025 will bring new opportunities and challenges to the power battery industry and promote the development of the whole industry to a safer, more reliable and more efficient direction. While responding to the new standards, enterprises also need to continuously optimize their own management and technical level to adapt to the new market environment.
