I. Introduction to Japan PSE Certification

PSE (Product Safety of Electrical Appliance & Materials) certification (referred to as "fitness inspection" in Japan) is a mandatory market access system for Japanese electrical appliances and an important part of the Japanese Electrical Appliances Safety Law. . At present, the Japanese government divides electrical appliances into "specific electrical appliances" and "non-specific electrical appliances" according to the provisions of the Japanese Electrical Appliances Safety Law. Among them, "specific electrical appliances" includes 116 kinds of products, which are diamond-shaped PSE certification; Non-specific electrical appliances" include 341 products and are round PSE certified. The PSE includes both EMC and security requirements. 

Second, the importance of battery PSE certification

The battery and battery are non-mandatory certifications in Japan. You can do a round PSE. A round PSE-certified battery product can give customers a guarantee of safety and reliability. In the market competition, it has a greater advantage than a battery product without certification, and the market share has increased. The popularity has also increased, and the market is strong and long-term.

Third, the battery PSE certification mark

The specific range of lithium-ion batteries currently exported to Japan must comply with the requirements of the supplier's declaration of conformity and must be affixed with a round PSE mark (see figure below). 

Fourth, the battery range of battery PSE certification

Since November 20, 2008, lithium-ion batteries have been included in the control of NSPs. That is, secondary lithium ion batteries (for mobile devices, desk notebooks, etc.) with an energy density exceeding 400 Wh/L. Except for the following lithium-ion batteries: lithium-ion batteries for medical equipment, industrial equipment, and automobiles; batteries that cannot be easily removed by soldering or other means to the product; batteries of special construction.

Five, battery PSE certification test standards
