Standards Formulation Launched for Electrochemical Storage
Standards Formulation Launched for Electrochemical Storage,
KC,
▍What is KC?
Since 25th 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
- KC certification standard for lithium battery：KC62133:2019
- 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 1st, 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.
Looking up in the National Public Service Platform for Standards Information, we will find out a series of standard formulation and revision led by China Electric Power Research Institute about electrochemical storage have launched. It involves the revision of lithium-ion battery standard for electrochemical energy storage, the technical regulation for mobile electrochemical energy storage system, the management regulation for grid connection of user-side electrochemical energy storage system, and the emergency drill procedure for electrochemical energy storage power station. Various aspects are included such as battery for electrochemical system, grid connection technology, current converter technology, emergency treatment, and communication management technology.
As Double Carbon Policy drives new energy development, to ensure the smooth development of new energy technology has become the key. The development of standards thus springs up. Otherwise, the revision of series of electrochemical energy storage standards indicates that electrochemical energy storage is the focus of new energy development in the future, and the national new energy policy will lean to the field of electrochemical energy storage.
The standards drafting units include National Public Service Platform for Standards Information, State Grid Zhejiang Electric Power Co., Ltd.- the Electric Power Research Institute, and Huawei Technologies Co., LTD. The involvement of Electric Power Research Institutes in the standard drafting indicates that the electrochemical energy storage will be the focus in the field of electric power application. This concerns about energy storage system, inverter and interconnection and other technologies..
Huawei’s participation in the development of the standard could pave the way for further development of its proposed digital power supply project, as well as Huawei’s future development in electric energy storage.
