Major changes in the GB 36276 draft for soliciting comments,
GB 36276,

▍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.

In August, the national standard Lithium ion Batteries for Electric Power Storage (GB/T 36276) revised by the National Technical Committee on Electric Power Storage of Standardization has been completed through three rounds of discussion and revision. At present, this draft has been open to the public for comment. The new version, which is expected to be released next year, will replace GB/T 36276:2018 version. GB/T 36276 is about the requirements of lithium-ion batteries for electric power storage applications, covering design, electrical performance, mechanical performance, thermal performance and other requirements. This standard focuses on the safety and quality of the large-scale application of lithium-ion batteries in the field of electric power storage. The implementation of this standard is helpful to ensure the safe operation of electrochemical energy storage power stations.
New added power characteristics and curve test: the measured charge and discharge energy under different charge and discharge powers should not be lower than the guaranteed value of charge and discharge energy under the power, and the curve of battery energy efficiency varying with power should be provided.
Overload charge and discharge performance test: formerly known as the rate charge and discharge performance test. The test of 4 times rated charge and discharge power is deleted, only the test of rated charge and discharge power and 2 times rated charge and discharge power are retained.
