▍What is CTIA CERTIFICATION?

CTIA, the abbreviation of Cellular Telecommunications and Internet Association, is a non-profit civic organization established in 1984 for the purpose of guaranteeing benefit of operators, manufacturers and users. CTIA consists of all U.S. operators and manufacturers from mobile radio services, as well as from wireless data services and products. Supported by FCC (Federal Communications Commission) and Congress, CTIA performs a large part of duties and functions that were used to be conducted by the government. In 1991, CTIA created an unbiased, independent and centralized product evaluation and certification system for wireless industry. Under the system, all wireless products in consumer grade shall take compliance tests and those complying with the relevant standards will be granted to utilize CTIA marking and hit store shelves of North American communication market.

CATL (CTIA Authorized Testing Laboratory) represents labs accredited by CTIA for testing and review. Testing reports issued from CATL would be all approved by CTIA. While other testing reports and results from non-CATL will not be recognized or have no access to CTIA. CATL accredited by CTIA varies in industries and certifications. Only CATL which is qualified for battery compliance test and inspection has access to battery certification for compliance to  IEEE1725.

▍CTIA Battery Testing Standards

a) Certification Requirement for Battery system Compliance to IEEE1725— Applicable to Battery Systems with single cell or multiple cells connected in parallel;

b) Certification Requirement for Battery system Compliance to IEEE1625— Applicable to Battery Systems with multiple cells connected in parallel or in both parallel and series;

Warm tips: Select above certification standards properly for batteries used in mobile phones and computers. Do not misuse IEE1725 for batteries in mobile phones or IEEE1625 for batteries in computers.

▍Why MCM？

● Hard Technology: Since 2014, MCM has been attending battery pack conference held by CTIA in US annually, and is able to obtain latest update and understand new policy trends about CTIA in a more prompt, accurate and active way. 

●Qualification: MCM is CATL accredited by CTIA and is qualified to perform all processes related to certification including testing, factory audit and report uploading.

Looking up in the National Public Service Platform for Standards Information, we will find out a series of standard formulation and revision led by China Electric Power Research Institute about electrochemical storage have launched. It involves the revision of lithium-ion battery standard for electrochemical energy storage, the technical regulation for mobile electrochemical energy storage system, the management regulation for grid connection of user-side electrochemical energy storage system, and the emergency drill procedure for electrochemical energy storage power station. Various aspects are included such as battery for electrochemical system, grid connection technology, current converter technology, emergency treatment, and communication management technology.
As Double Carbon Policy drives new energy development, to ensure the smooth development of new energy technology has become the key. The development of standards thus springs up. Otherwise, the revision of series of electrochemical energy storage standards indicates that electrochemical energy storage is the focus of new energy development in the future, and the national new energy policy will lean to the field of electrochemical energy storage.
The standards drafting units include National Public Service Platform for Standards Information, State Grid Zhejiang Electric Power Co., Ltd.- the Electric Power Research Institute, and Huawei Technologies Co., LTD. The involvement of Electric Power Research Institutes in the standard drafting indicates that the electrochemical energy storage will be the focus in the field of electric power application. This concerns about energy storage system, inverter and interconnection and other technologies..
Huawei’s participation in the development of the standard could pave the way for further development of its proposed digital power supply project, as well as Huawei’s future development in electric energy storage.
