ALPHA Information Announcement: Requirements for Lithium Battery J62133 and Stacking Test Reports

On November 4, 2022, Japan's Ministry of Economy, Trade and Industry METI released a solicitation of opinions on the revision of lithium battery technical standards and regulations on its official website, with a deadline of December 3, 2022. Revised content: As Table 9 does not have a method for monitoring the voltage of each cell/cell block in the battery pack, it is recommended to abolish Table 9 and unify it with J62133-2 in Table 12 that matches recent international standards.

Interpretation of Alpha Safety Regulations：

On August 26, 2022, the IECEE official website released the Japanese deviation J62133-2 (2021) (JPND) of IEC62133-2, which means that CB reports with Japanese deviations can replace PSE reports and issue PSE certificates.

If the cell and battery already have CB according to IEC62133-2:2017, the Japanese deviation needs to be supplemented with the following difference tests:

1. Battery cell constant voltage charging for 28 days

2. Conduct Temperature cycling test on battery cell and battery respectively

3. Cell Low-pressure area test

4. High rate charging of battery cells

5. Forced internal short circuit of battery cell

6. Battery overvoltage

7. Drop (if applicable)

About UN38.8

In order to effectively ensure the safety of battery air transportation and avoid unsafe incidents, various airports need to collect and transport batteries of each type during the transportation process

Proof of compliance with section 38.3 (i.e. UN38.3) of the "Handbook of Tests and Standards for the Transport of Dangerous Goods in China", without a UN38.3 conformity report

The goods cannot be collected and shipped. So the requirements for lithium batteries are becoming increasingly strict. In the 2023 IATA DGR64th (2023 version) lithium battery aviation transportation packaging

Added stacking testing requirements.
