7.4 安全性能 Safety Performance.
7.4.1 外部短路测试 External Short-Circuiting Test (25±2ºC)
电芯以标准模式充电, 将电芯的正极和负极以一根电阻为100mΩ的导线相连接, 并维持1小时。
标准: 不起火,不爆炸, 电芯表面温度不超过150℃。
Cells are charged per Standard Charge, and the positive and negative terminal is connected by a 100mΩ-wire for 1hour .
Criteria : No fire, No explosion, The temp of the exterior cell shall not exceed 150℃.
7.4.2 热冲击测试 Heating Test
电芯以标准模式充电, 置入鼓风烘箱中并以5℃/min的速率升温至130℃,在130℃下维
持30min。
标准: 不起火,不爆炸
Cells are charged per Standard Charge and heated in a circulating air oven at a rate of 5ºC
per minute to 130ºC. and remain then oven at 130ºC for 30 minutes.
Criteria: No fire, No explosion.
7.4.3 过充电测试 Overcharge Test
电芯以标准模式放电, 然后以3C恒定电流充电直到电压达到5V并维持7.小时, 测
试中应没有任何保护措施。
标准: 不起火,不爆炸
Cells are discharged per Standard Charge, then charged at constant current of 3C till the voltage reaches 5V for 7hrs. Not should have any protect during testing.
Criteria: No fire, No explosion.
7.4.4 过放电测试 Overdischarge Test
电芯以标准模式放电后,然后用30Ω的电阻将电池正负极相连24h。
标准: 不起火,不爆炸
Cells are discharged per Standard Charge, then connect the positive and negative terminals with a resistor of 30Ω for 24 hours.
Criteria: No fire, No explosion.
