As an important energy storage device, batteries are widely used in modern society. In order to ensure the safety, performance and reliability of batteries, various countries and international organizations have formulated a series of battery testing standards. This article will summarize and introduce the battery testing standards to help readers better understand the relevant standards of battery testing.

1. Overview of battery testing standards

battery testing standards cover the safety, performance, life, environmental adaptability and other requirements of the battery to ensure the normal operation of the battery in different use scenarios. The main battery testing standards include:

• national standards: Standards formulated by various countries covering domestic battery industry, such as China's lithium ion battery industry standards;
• industry standards: standards issued by battery industry associations or organizations, such as battery standards issued by the International Electrotechnical Commission (IEC);
• international standards: standards issued by the International Organization for Standardization (ISO) covering the battery industry worldwide.

These standards provide unified specifications and guidance for the design, manufacture, testing and evaluation of batteries.

2. Introduction to main battery testing standards

IEC 62133-2 is the battery safety standard issued by IEC, which mainly includes the structure, electrical performance, safety performance, environmental test and other contents of the battery, and is suitable for lithium ion batteries, Ni-MH batteries and other types of batteries.

(2) GB/T 18287

GB/T 18287 is an industry standard for lithium-ion batteries formulated by China, including the classification, specifications, requirements, test methods and other contents of lithium-ion batteries, which is applicable to all kinds of lithium-ion battery products.

(3) ISO 12405

ISO 12405 is the battery performance test standard issued by ISO, including battery charging and discharging performance, cycle life, internal resistance test and other contents, which is suitable for various types of batteries.

3. Application field of battery testing standards

battery testing standards are widely used in battery design, production and testing.And the use process mainly includes the following fields:

• battery Design: design the structure, parameters and performance indicators of the battery according to the requirements of the standard;
• battery Production: follow the standard requirements in the battery production process to ensure battery quality and safety;
• battery Test: when conducting battery performance test and safety test, conduct test methods and data analysis according to standards;
• battery Usage: in the process of battery usage, battery maintenance, charge and discharge management and other operations are carried out according to the requirements of the standard.

4. Importance of battery testing standards

the formulation and compliance of battery testing standards are of great significance for ensuring the safety, performance and reliability of batteries, which are mainly reflected in the following aspects:

• ensure the safety of users: standardize the design and manufacture of batteries through standards to effectively ensure the safety of users;
• improve battery performance: The standard requires the battery to have a certain performance index and promote the battery increased performance;
• promoting industrial development: the formulation and compliance of standards have promoted the development and standardization of battery industry.
