振动 | 在三个相互垂直的方向按单振幅0.38mm(振动频率10~30Hz)、0.19mm(振动频率30~55Hz)循环扫描振动30min,扫频速度为1oct/min。 | 电池应不爆炸不起火,此外,还应不冒烟,不漏液 | OK | OK |
碰撞 | 在三个相互垂直的方向以100m/s2脉冲峰值加速度及16ms的脉冲持续时间,冲击1000±10次。 | OK | OK |
自由跌落 | 电池从1m高处自由落到20mm厚的木板上,在三个相互垂直的方向各进行2次(正负方向各1次)。再以1C5A电流进行充放电循环3次。 | 电池无漏液、无冒烟、无爆炸;放电时间≥51min | OK电池外观良好 | OK少量电池轻微胀气 |
重物冲击 | 电池放置于冲击台上,将10kg重锤自1m高度自由落下,冲击已固定在夹具中的电池。 | 电池应不爆炸不起火 | OK | OK |
热冲击 | 将电池置于重力对流炉或鼓风加热炉中。以每分钟5±2℃的速率升温至150±2℃,并保持这个温度10min直至测试结束。 | OK电池外观良好 | OK少量电池胀气较严重 | |
过充电 | 将接有热电偶的电池置于通风橱中,接正负极于恒流恒压源,调节电流至3C5A、电压为5V。然后对电池以3C5A充电,直至电池电压为5V,电流接近于0A。 | 电池应不爆炸、不起火、不冒烟、不漏液 | OK电池外观良好 | OK少量电池轻微胀气 |
短路 | 将接有热电偶的电池置于通风橱中,短路其正负极(线路总电阻不大于50mΩ),试验过程中监视电池温度变化。当电池温度下降到比峰值低约10℃时,结束试验。 | 电池不起火、不爆炸。电池外表面温度不超过150℃ | OK电池外观良好 | OK少量电池轻微胀气 |
