UL1973 certification is a safety standard for energy storage batteries in North America, which is a voluntary certification. The standard covers all types of energy storage batteries used in photovoltaics, wind energy, backup power supplies, and communication base stations, and includes structural evaluation and test evaluation of energy storage systems. Its scope of application includes not only the energy storage battery itself, but also the battery management system, cables, connectors, sensors and other related accessories and equipment that make up the lithium battery system. All links in the entire battery chain, including the battery module, need to comply with this standard.
The UL1973 standard was published on February 15, 2013, which not only evaluates the safety of batteries, but also covers the electrochemical performance of batteries. This means that it not only focuses on the safety risks of the battery during use, but also on the performance and reliability of the battery. In addition, UL1973 certification is also applicable to various types of lithium batteries, including lithium-ion batteries, lithium-polymer batteries, and lithium-iron batteries.
In the process of applying for UL1973 certification, module certification is an important link. The module certification process includes steps such as submission of application, document review, and sample testing. Applicants are required to submit the module certification application to UL or its authorized representative, and provide relevant documents and information, including detailed module specifications, design drawings, test records, etc. UL's engineers will review the submitted documents to ensure that the module design meets the requirements of the UL1973 standard. After that, according to the requirements of the UL1973 standard, the corresponding number of samples are submitted for testing.
Overall, UL1973 certification is an important procedure to ensure that energy storage batteries are safe, reliable, and stable in the North American market. Through this certification, consumers can have more trust in the products that use these batteries, and at the same time, it will also help promote the healthy development of the energy storage battery industry. The importance of UL1973 certification in the energy storage battery industry is self-evident, it provides consumers with a guarantee that the energy storage batteries they buy are safe and reliable. In addition, this certification also helps to improve the reputation and credibility of the energy storage battery industry, attracting more consumers and investors.

However, UL1973 certification is not the only certification standard. In the energy storage battery industry, there are many other certification standards and test procedures to ensure the performance and safety of batteries. These standards and test procedures are often developed by international organizations or industry associations and are recognized and accepted worldwide.
In addition to UL1973 certification, there are a number of other certification standards and test procedures, such as:
1.IEC 62619 standard: This is an international standard designed to ensure the safety and performance of energy storage batteries. It involves aspects such as testing, evaluation, and certification of batteries to ensure that batteries can work safely and reliably in a variety of environments and conditions.
2.UL 2580 standard: This is a safety test and evaluation standard for power lithium batteries used in electric vehicles. It involves the testing of overcharge, short circuit, over-discharge and other aspects of the battery to ensure that the battery will not have safety problems such as fire or ** during use.
3. un38.3 Standard: This is a test and evaluation standard for lithium batteries. It involves the testing of the stability, safety, operability and other aspects of the battery to ensure that the battery will not have safety issues such as fire or ** during transportation.
The existence of these certification standards and test procedures enables the healthy development of the energy storage battery industry and ensures that consumers can purchase safe and reliable energy storage battery products. However, it is not easy for companies to obtain these certifications, and it requires a lot of human, material and financial resources. Therefore, enterprises should choose the certification standards and testing procedures suitable for their products according to their own circumstances to ensure the safety and reliability of their products.
