Test Method and Condition

Criteria

1

Thermal exposure test

Each fully charged cell, stabilized at room temperature, is placed in a circulating air-convection oven. The oven temperature is raised at a rate of 5 °C/min ± 2 °C/min to a temperature of 130 °C ± 2 °C. The cell remains at this temperature for 10 min before the test is discontinued.

No explosion, No fire

2

Short test

The fully charged battery is to be short-circuited by connecting the positive and negative terminals of the battery with resistance load not exceed 100mΩ.Tests are to be conducted at room temperature 20~25℃.

No explosion, No fire

The Temperature of the Battery surface not exceeded than 150℃

3

Short test

The fully charged battery is to be short-circuited by connecting the positive and negative terminals of the battery with resistance load not exceed 100mΩ.Tests are to be conducted at room temperature about 60-65℃

No explosion, No fire

The Temperature of the Battery surface not exceeded than 150℃

4

Forced discharge test

A discharged cell is subjected to a reverse charge at 0.5C for 150 min.

No explosion, No fire
