Summary of changes to the new IEC 62619 version,
IEC 62619,

▍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.

IEC 62619: 2022 (the second version) released on 24 May 2022 will replace the first version published in 2017. IEC 62169 covers the safety requirements of secondary lithium ion cells and batteries for industrial use. It is generally considered to be a test standard for energy storage batteries. But in addition to energy storage batteries, IEC 62169 can also be used for lithium batteries used in uninterruptable power supplies (UPS), automatic transport vehicles (ATV), emergency power supplies and marine vehicles.
There are six major changes, but the most significant one is to add requirements for EMC.
EMC testing requirements have been added to a growing number of battery standards, especially for large power and energy storage systems, including standard UL 1973 released this year. In order to meet EMC testing requirements, manufacturers should optimize and improve circuit design and use of electronic components, and conduct preliminary verification on trial-produced products to ensure that EMC requirements are met.
