PSE (Product Safety of Electrical Appliance & Materials)) certification (called "suitability inspection" in Japan) is a compulsory market access system for electrical products in Japan and an important content stipulated in Japan's electrical products safety law. At present, according to the provisions of Japan's electrical supplies safety law, the Japanese government divides electrical supplies into "specific electrical supplies" and "non-specific electrical supplies". The "specific electrical supplies" includes 116 kinds of products, which are subject to diamond PSE certification; " "Non specific electrical products" includes 341 products, which are certified by circular PSE. PSE includes EMC and security requirements.

Batteries and cells are non compulsory certification in Japan, and circular PSE can be used. Only by making round PSE certified battery products can we give customers a guarantee of safety and reliability in the market competition Compared with the battery products without certification, it seems to have greater advantages. The market share has increased, the popularity has also improved, and it can occupy the market effectively and in the long run.

Since November 20, 2008, lithium-ion batteries have been included in the control scope of NSPs. That is, secondary lithium-ion batteries with an energy density of more than 400 WH / L (for mobile devices, desktop notebooks, etc.). The following lithium-ion batteries are excluded: lithium-ion batteries for medical equipment, industrial equipment and automobiles; Batteries that are fixed to the product by welding or other means and cannot be easily removed; Battery with special structure.
