Lithium-ion Batteries in Energy Storage Systems Shall Meet Requirements of GB/T 36276,
Energy Storage Systems,

▍What is KC?

Since 25^th Aug., 2008，Korea Ministry of Knowledge Economy (MKE) announced that the National Standard Committee will conduct a new national unified certification mark — named KC mark replacing Korean Certification during the time between Jul. 2009 and Dec. 2010. Electrical Appliances safety certification scheme (KC Certification) is a mandatory and self-regulatory safety confirmation scheme according to Electrical Appliances Safety Control Act, a scheme which certified safety of manufacture and sale. 

The difference between mandatory certification and self-regulatory (voluntary) safety confirmation：

For the safe management of electrical appliances, KC certification is divided into mandatory and self-regulatory  (voluntary) safety certifications as the classification of danger of  product.The subjects of Mandatory certification is applied to electrical appliances which its structures and methods of application may cause serious dangerous results or obstacle such as fire, electric shock. While the subjects of self-regulatory (voluntary) safety certification is applied to electrical appliances which its structures and methods of application can hardly causes serious dangerous results or obstacle such as fire, electric shock. And the danger and obstacle can be prevented by testing the electrical appliances.

▍Who can apply for KC certification：

All legal persons or individuals both at home and abroad who are engaged in manufacturing, assembly, processing of electrical appliance.

▍Scheme and method of safety certification：

Apply for KC certification with product’s model that can be divided into basic model and series model.

In order to clarify model type and design of electrical appliances, an unique product name will be given according to its different function.

▍ KC certification for Lithium battery

1.  KC certification standard for lithium battery：KC62133:2019
2. Product scope of KC certification for lithium battery

A. Secondary lithium batteries for use in portable application or removable devices

B. Cell is not subject to KC certificate whether for sale or assembled in batteries.

C. For batteries used in energy storage device or UPS (uninterruptible power supply), and their power which is greater than 500Wh are beyond the scope.

D. Battery whose volume energy density is lower than 400Wh/L comes into certification scope since 1^st, Apr. 2016.  

▍Why MCM?

● MCM keeps a close cooperation with Korean labs, such as KTR (Korea Testing & Research Institute) and is able to offer the best solutions with high cost performance and Value-added service to clients from the point of lead time, testing process, certification cost.

● KC certification for rechargeable lithium battery can be gained by submitting a CB certificate and convert it into KC certificate. As a CBTL under TÜV Rheinland, MCM can offer reports and certificates which can be applied for conversion of KC certificate directly. And the lead time can be shortened if applying CB and KC at the same time. What’s more, the related price will be more favorable.

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):1. 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.
