▍Brief introduction to certification of energy storage battery
♦ CB Certification—IEC 62619
● Introduction
▷ CB certification is an international certification created by IECEE. Its goal is “One test, multiple applications”. The aim is to achieve mutual recognition of product safety test results from laboratories and certification bodies within the scheme worldwide, so as to facilitate international trade.
● The advantages of obtaining CB certificate and report are as follows:
▷ Used for certificate transfer (e.g. KC certificate).
▷ Meet the requirements of IEC 62619 for battery system certification in other countries or regions (e.g. CEC in Australia).
▷ Meet the requirements of end product (forklift) certification.
● Scope
▷ Lithium battery for mobile equipment: Forklift, golf cart, AGV, railway, ship;
▷ Lithium battery for fixed equipment: Uninterruptible power supply (UPS), energy storage equipment, emergency power supply.

♦ EU EESS battery requirements (CE certification - EU New Batteries Regulation
● Applicable Scope
The new EU batteries regulation divides industrial batteries into two categories, as follows:
Industrial batteries: weight > 5kg, traction batteries for industrial transport vehicles (such as: railways, mechanical equipment, forklifts), communication infrastructure batteries, household energy storage batteries, etc.
Stationary BESS system: an industrial battery with internal storage that is specifically
designed to store from and deliver electric energy to the grid or store for and deliver electric energy to end-users.

♦ North America ESS Certification
● Introduction
The installation and usage of ESS in North America should comply with local laws and regulations from American fire department. The requirements cover aspects of design, test, certification, fire fight, environment protection and so on. As a critical component of ESS, lithium-ion battery system should comply with following standards.
