▍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.

According to the official website of PSE certification, the standard has not been updated yet till now. The current standard of battery PSE certification is still Appendix 9 or JIS C 8712: 2015 (As below screenshot). And after communicated with METI, they confirmed there is no plan to adopt JIS C 62133-2: 2020 to be the standard of certification at present.
Currently the standard of battery PSE certification is mainly Appendix 9. Lots of manufactures worry about the cell overcharge test in this standard. Technically the test may easily fail because the voltage used in this test is over 10V. However, in the Japanese version Appendix 9, the definition of the cell used in this test clearly says the cell shall include the protective parts assembled in the device or battery. Hence it is not likely to fail easily as manufacturers’ worry.
JIS C 62133-2: 2020 is referred to IEC 62133-2: 2017. If it becomes the standard of PSE certification, the testing time, samples and testing fee will all be reduced. That is why the clients
care about it.
