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

▍What is PSE Certification?

PSE (Product Safety of Electrical Appliance & Material) is a mandatory certification system in Japan. It is also called ‘Compliance Inspection’ which it is a mandatory market access system for electrical appliance. PSE certification is composed of two parts: EMC and product safety and it is also an important regulation of Japan safety law for electrical appliance.

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.
