With the popularization of electronic products such as electric vehicles and smart phones, lithium-ion batteries have become one of the mainstream battery technologies. However, due to the potential safety hazards that may exist during its use, China has formulated a series of mandatory standards to ensure the safety of users and the environment. Among them, GB31241 is the specific standard for the safety of lithium ion batteries. This article will discuss the contents and requirements of GB31241 standards in depth.

GB31241 standard overview

GB31241 standard is issued by China National Standards Committee 《 lithium ion power battery the abbreviation of safety requirements and test methods is a mandatory standard that regulates the safety requirements and test methods of lithium ion battery products. This standard aims to ensure the safety of lithium ion battery products in the process of design, production and use, and effectively prevent fire, explosion and other safety accidents.

GB31241 standard content

the GB31241 standard mainly includes the following contents:

1. product Range: specifies which types of lithium ion battery products are applicable, including power batteries, energy storage batteries, etc.

2. Terms and Definitions: for lithium ion battery phaseRelevant Terms and definitions are explained to facilitate the understanding and application of standards.

3. Safety requirements: including battery structure design, material selection, safety protection function, overcharge and overdischarge protection, short circuit protection and other safety requirements.

4. Performance Test: test the battery capacity, cycle life, charge and discharge performance, temperature characteristics and other performance requirements.

5. Environmental adaptability: test and evaluate the environmental adaptability of the product considering the use of the battery under different environmental conditions.

6. Signs and logos: The product must be marked with a GB31241 certification mark so that consumers and regulators can identify the certified product.

GB31241 standard requirements

the GB31241 standard puts forward strict requirements on the safety and performance of lithium ion battery products, mainly including the following aspects:

1. structural Safety: the structural design of the battery must meet the requirements to ensure that there will be no safety problems such as short circuit or thermal runaway under normal use conditions.

2. Security protection function: the battery must have safety protection functions such as overcharge and overdischarge protection, short circuit protection, and temperature protection to prevent accidents.

3. stable performance: the capacity, cycle life, charge and discharge performance of the battery must be stable and reliable, and meet the specified performance indicators.

4. Environmental adaptability: the performance of the battery under different environmental conditions such as temperature and humidity must meet the requirements to ensure the safe and reliable use of the product in various environments.

5. Signs and logos: the product must be marked with a GB31241 certification mark to show that it has passed the corresponding safety test and certification.

The importance of GB31241 standards

the formulation and implementation of GB31241 standards are of great significance for lithium ion battery products:

1. product Security: the implementation of the GB31241 standard can effectively improve the safety of lithium-ion battery products and reduce safety risks.

2. Regulatory compliance: compliance with the GB31241 standard is a necessary condition for products to be listed, ensuring that products comply with relevant regulations and standards.

3. Consumer trust: Certified products can enhance consumers' trust and desire to buy products.
