▍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.

On June 21, 2022, the website of Chinese Ministry of Housing and Urban-Rural Development released the Design Code for Electrochemical Energy Storage Station (Draft for Comments). This code was drafted by China Southern Power Grid Peak and Frequency Regulation Power Generation Co.,Ltd. as well as other companies, which are organized by Ministry of Housing and Urban-Rural Development. The standard is intended to apply to the design of new, expanded or modified stationary electrochemical energy storage station with a power of 500kW and a capacity of 500kW·h and above. It is a compulsory national standard. The deadline for comments is July 17, 2022.
The standard recommends to use of lead-acid (lead-carbon) batteries, lithium-ion batteries and flow batteries. For lithium batteries, the requirements are as follows (in view restrictions of this version, only the main requirements are listed):
The technical requirements of lithium-ion batteries shall comply with the current national standard Lithium-ion Batteries Used in Power Storage GB/T 36276 and the current industrial standard Technical Specifications for Lithium-ion Batteries Used in Electrochemical Energy Storage Station NB/T 42091-2016.
