No. | Item 项目 | Test Meth and Condition 测试方法和条件 | Criteria 标准 |
8.1 | Overcharge testing （NO PCM） 过充测试 (无保护板) | At standard testing t_____________________________________________________________________________________________________________________condition，charging lithium ion battery with constant current 0.2I5A和I5A to voltage 6.0V, then with constant voltage 6.0V till current decline to 0. Stop test till cells 在标准测试环境下，分别用 压60V让电流下降接近为0A,停止实验. | No smoke or fire 不起火,不冒烟
|
8.2 | Over-discharge testing/ （NO PCM） 过放测试 (无保护板) | At standard testing condition，the lithium ion battery will be discharge to cut-off voltage, then to connect 30Ω load discharge 24 hours. 在标准测试环境下，按标准放电的要求放电至终止电压，再连接30Ω负载放电24小时。 | No fire, no smoke, no leakage. 无起火,无冒烟,无泄液 |
8.3 | Crush Test 挤压测试 | A lithium ion battery is to be placed on the crush flat, the axis is parallel to the crush flat ,it is to be crushed between two flat surfaces. Crushing force is approximately 13 KN and hold for 1 min 电池放在挤压设备的两个挤压表面之间，圆柱电芯轴平行于挤压平面，逐渐增加压力至13 kN，保持压力1min。 | no fire,no explosion 电池不起火，不爆炸 |
8.4 | Short-circuit Test 短路测试 | A Cell is to be short-circuited by connecting the positive and negative terminals of the cell with copper wire having a maximum resistance load of 50mΩ.Monitor its temperature while testing,the cell is to be discharged until the lithium ion battery case temperature has returned to be 10℃ less then peak temperature. 将接有热电偶的电芯置于通风橱中，用铜线短路其正负极(线路总电阻不大于50毫欧)，实验过程中监视电芯温度变化，当电池温度下降到比峰值低约10℃时，结束实验。 | 1. no fire,no explosion 2. Max.temp< 150℃
1. 电池不起火，不爆炸。 2. 最高温度<150℃ |
8.5 | Nail penetration Test 针刺测试 | A cell is to be penetrated completely the center of the largest side at the speed of 20-40mm per second by a Φ3.0mm stainless steel nail . 将接有热电偶的电芯置于通风橱中，用Φ3.0mm的不锈钢针以 20-40mm/s的速度刺透电芯最大表面的中心位置。 | no fire,no explosion 电池不起火，不爆炸 |
8.6 | Impact Test 重物冲击 | A lithium ion battery is to be placed on the impact flat.A Φ15.8mm bar is to be placed on the center of the cell.A 9.1kg weight is to be dropped from a height of 610mm onto the cell, the distortion is allowed. 将电池放在冲击台上，将一Φ15.8mm的钢柱置放电池中心，钢柱的纵轴平行于平面，让重量9.1kg重锤自610mm高度自由落下，冲击电芯，电芯允许发生变形。 | no fire,no explosion 电池不起火，不爆炸 |
