Criteria 标准 |

1 |
Thermal exposure test 高温热冲击测试 |
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. 充满电的电池温度稳定到常温后，放置入循环空气烘箱里，从常温以5 °C/分± 2 °C/分的速率升至130°C后，在130°C放置10分钟。 |
No fire, No explosion 无起火，无爆炸 |
|
2 |
Low pressure 低压测试 |
Each fully charged cell is placed in a vacuum chamber, in an ambient temperature of 20~25℃. Once the chamber has been sealed, its internal pressure is gradually reduced to a pressure equal to or less than 11.6 kPa (this simulates an altitude of 15240 m) held at that value for 6 h. 电池放在一个模拟真空的空间放置6小时，环境温度为20~25℃，真空环境压力≤11.6kpa，模拟15240m高空低压环境 |
No leakage, No fire, No explosion 无泄漏，不起火，不爆炸 |
|
3. |
Short test 短路测试 |
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℃. 在室温20~25℃把充满电的电池的正负极用不超过100mΩ的负载连接起来，连接起来使电池外部短路 |
No fire, No explosion The Temperature of the Battery surface not exceeded than 150℃ 无起火，无爆炸 电池表面温度不超过150℃ |
|
4 |
Forced discharge test 过放电测试 |
A discharged cell is subjected to a reverse charge at 1C for 90 min. 将电芯放完电，再用1C反接充电90分钟 |
No fire, No explosion 无起火，无爆炸 |
|
5 |
Over charge test 过充电测试 |
After standard charge, continue to charge with a constant voltage 4.6V per a cell, holding 8h. 电芯标准充满电后，以4.6V的恒定电压继续充电，保持8小时 |
No leakage, No fire, No explosion 无泄漏，不起火，不爆炸 |
|
6 |
Soak Test 浸泡测试 |
Put the batteries into clean water, be soaked for 24 hours. 把电池放进清水中浸泡24个小时 |
No break, No fire 无破裂，无起火 |
