Discussion meeting on Certification Technical Rules of Robot Battery,
Robot Battery,

▍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.

The domestic robot industry is under developing, but the size and performance of each battery pack are different. Most of batteries are customized, so relevant standards are needed to normalize the industry. And there is no battery certification in the current certification system, so the CR certification projected approval for robot battery, and held a discussion conference on Certification Technical Rules of Robot Battery in September. This is applicable to robot batteries, including household or commercial service robots, special robots, automatic guided vehicles, composite robots and other robot products. The test items refer to the electronic industry standard General Specification for Lithium-ion Batteries and Battery Packs for Service Robots, IEC 62133, IEC 62619 and UN38.3. The test items included high and low temperature performance test, safety test, battery pack protection test and BMS system evaluation and functional safety.Recently, IECEE officially issued and immediately took effect three battery CTL resolutions, mainly related to the CB certification standard IEC 62133 of lithium batteries. These three resolutions have been issued before, and the reason for re-issuing is to increase the standard scope applicable to the resolution. For example, IEC 62619, IEC62660 and other standards are added to DSH10037A. The following are the specific contents of the resolutions:Resolution 1 (DSH 2182) : There are two methods for IEC 62133-2 , in which method 2 requires charging cutoff current to be 0.05 ItA, even though the manufacturer has defined a different cutoff current. However, you can provide samples for testing with the different cutoff voltage, and the results will be as a reference.
