Short circuit 短 路 |
Test battery at 20±5℃ and 55±5℃, put battery joining thermocouple (contact of thermocouple fixed on center surface of battery) into fume hood and high temperature oven, short circuit battery at 55±5℃ and remain 1.5~2h at the temperature. Make battery short circuit, total impedance no more than 100mΩ till battery load voltage less than 0.1V and surface temperature are recovered to no more than 10℃, test end. 试验应分别在20±5℃和55±5℃的环境温度下进行。将接有热电偶的电池（热电偶的触点固定在电池大表面的中心部位）分别置于通风橱和高温箱中（进行55±5℃的短路电池应先在次温度下保持1.5~2h），短路其正负极，线路总电阻不大于100mΩ，直到电池负载电压小于0.1V，并且电池表面温度恢复至不高于环境温度10℃时，结束试验。 |
No fire, no explosion, battery surface no more than 150℃. 不起火、不爆炸、电池表面温度不高于150℃ |
|
Puncture 针 刺 |
Test battery at 20±5℃ and 55±5℃, put battery joining thermocouple( fix contact of thermocouple fixed on center surface of battery) into fume hood and puncture battery with a antirust steel needle of diameter 3m and 20mm~40mm/s speed and keep 1min. 标准充电后，在20±5℃的环境温度下，将接有热电偶的电池（热电偶的触点固定在电池表面的中心部位）置于通风橱中，用直径3mm的无锈蚀钢针以20mm~40mm/s的速度刺穿电池表面的中心位置，并保持1min。 |
