▍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.
▍Certification Standard for lithium batteries
Interpretation for METI Ordinance for Technical Requirements(H25.07.01)， Appendix 9，Lithium ion secondary batteries

In the previous journals, we’ve mentioned some of devices and components testing requirements in GB 4943.1-2022. With the increasing use of battery-powered electronic devices, the new version of GB 4943.1-2022 adds new requirements based on 4.3.8 of the old version standard, and the relevant requirements are put into Appendix M. The new version has more comprehensive consideration on devices with batteries and protection circuits. Based on the evaluation of battery protection circuit, additional safety protection from devices are also required.1.Q: Do we need to conduct Annex M test of GB 4943.1 with compliance of GB 31241?
A: Yes. GB 31241 and GB 4943.1 Appendix M cannot replace each other. Both standards should be met. GB 31241 is for the battery safety performance, regardless of the situation on the device. Annex M of GB 4943.1 verifies the safety performance of batteries in devices.
