▍Certification Overview

Standards and Certification Document

Test standard: GB31241-2014: Lithium ion cells and batteries used in portable electronic equipment―Safety requirements
Certification document: CQC11-464112-2015: Secondary Battery and Battery Pack Safety Certification Rules for Portable Electronic Devices

Background and Date of implementation

1. GB31241-2014 was published on December 5^th, 2014;

2. GB31241-2014 was mandatorily implemented on August 1^st, 2015. ;

3. On October 15th, 2015, Certification and Accreditation Administration issued a technical resolution on additional testing standard GB31241 for key component “battery” of the audio and video equipment, information technology equipment and telecom terminal equipment. The resolution stipulates that the lithium batteries used in the above products need to be randomly tested as per GB31241-2014, or obtain a separate certification. 

Note: GB 31241-2014 is a national compulsory standard. All the lithium battery products sold in China shall conform to GB31241 standard. This standard will be used in new sampling schemes for national, provincial and local random inspection.

▍Scope of Certification

GB31241-2014 Lithium ion cells and batteries used in portable electronic equipment―Safety requirements
Certification documents is mainly for mobile electronic products that are scheduled to be less than 18kg and can be often carried by users. The main examples are as follows. The portable electronic products listed below do not include all products, so products not listed are not necessarily outside the scope of this standard.

Wearable equipment: Lithium-ion batteries and battery packs used in equipment need to meet standard requirements.

Certification of electric vehicle batteries/storage batteries
The preparation of new site and equipment is to perform more comprehensive services. We are expanding our business and get deep into international certification with TUV RH of storage batteries and electric two-wheel vehicles batteries. Meanwhile we cooperate with EPRI in power grid storage. We will be able to test products of more elaborated design. We will also start projects of certification in transport area, and coordinate with CAAC to gain more resources of air transport.
Our faith:
MCM live from customers and work for customers. We have been keeping and will ever keep on our mission: to make certification and testing simple and pleasant.
Append 18 Overload Under Discharge: Evaluate battery system ability with overload under discharge. There are two conditions for the test: first is in overload under discharge in which current is higher than rated maximum discharging current but lower than current of BMS overcurrent protection; the second is higher than BMS over current protection but lower than level 1 protection current.
