What is JIS C62133-2 Compliance Testing?

To meet the market access requirements in Japan, lithium batteries (with an energy density greater than 400 Wh/L) must obtain the pse certification mark through Japan's Electrical Appliance and Material Safety Law. On December 21, 2020, the Japanese Industrial Standards Committee (JISC) published the standard JIS C 62133-2:2020.

Test Items:

- 7.2.128-day constant voltage charge (cell)

- 7.2.2High-temperature molded stress (battery pack)

- 7.2.2ATemperature cycling

- 7.3.1External short circuit (cell)

- 7.3.2External short circuit (battery pack)

- 7.3.3Free fall

- 7.3.4Thermal abuse (cell)

- 7.3.5Crush (cell)

- 7.3.6Overcharge (battery pack)

- 7.3.7Forced discharge (cell)

- 7.3.8.1Vibration (battery pack)

- 7.3.8.2Shock (battery pack)

- 7.3.8ALow pressure (cell)

- 7.3.8BHigh-rate charge (cell)

- 7.3.8CDevice drop (battery pack)

- 7.3.8DOvercharge protection (battery pack)

- 7.3.9Forced internal short circuit (cell)

- Appendix DAC internal resistance of button cells

On August 26, 2022, the IECEE website released the Japanese deviation of IEC62133-2, J62133-2(2021) (JP ND). This means that a cb report with Japanese deviation can replace a PSE report and be used to issue a pse certificate.

If a cell and battery (battery weight not exceeding 7 kg) already have a cb certificate under IEC62133-2:2017, the Japanese deviation requires the following supplementary difference tests:

1. 28-day constant voltage charge (cell)

2. Temperature cycling test (cell + battery)

3. Low pressure test (cell)

4. High-rate charge (cell)

5. Forced internal short circuit (cell)

6. Overcharge protection (battery)

7. Drop test of battery installed in equipment (portable devices ≤ 7 kg, stationary devices ≤ 5 kg)
