▍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.

Overview:
Electric scooter and skateboard are included under UL 2271 and UL 2272 when certificated in North America. Here is the introduction, on the range they cover and requirements, of distinctions between UL 2271 and UL 2272:UL 2271 is about batteries on various devices; while UL 2272 is about personal mobile devices. Here are lists of matters covered by the two standards:
L 2271 covers light vehicle batteries, including:
Electric bicycle；
Electric scooter and motorcycle；
Electric wheelchair；
Golf cart；
ATV；
Unmanned industrial carrier (e.g. electric forklift)；
Sweeping vehicle and mower；
Personal Mobile Devices (Electric Balance scooters)
UL 2272 is available for personal mobile devices, such as: electric scooters and balance cars.
From the standard scope, UL 2271 is the battery standard, and UL 2272 is the device standard. When doing the device certification of UL 2272, does the battery need to be certified to UL 2271 first?
First, let’s know about the requirements of UL 2272 for batteries (only lithium-ion batteries/cells are considered below):
Cell: lithium-ion cells must meet the requirements of UL 2580 or UL 2271;
Battery: If the battery meets the requirements of UL 2271, it can be exempted from the tests for overcharge, short-circuit, over-discharge and unbalanced charging.
It can be seen that if the lithium battery is used in the equipment that is applicable to UL 2272, it is not necessary to do UL 2271 certification, but the cell needs to meet the requirements of UL 2580 or UL 2271.
In addition, the requirements of the vehicles’ battery applying to UL 2271 for cell are: lithium-ion cells need to meet the requirements of UL 2580.
To sum up: as long as the battery meets the requirements of UL 2580, the test of UL 2272 can completely ignore the requirements of UL 2271, that is, if the battery is only used for equipment that is suitable for UL 2272, it is not necessary to do UL 2271 Certification.
