9.1
Over charge
testing
过充测试
At 20
±
5
℃
, charging cells with constant current 2C to
voltage 5.0V, Stop test till cells temperature 10
℃
lower than
max temperature.
在 20±5℃状态下,电池用 2C 电流充电至 5.0V,监视电池温
度变化,当电池温度下降一峰值低约 10℃时,停止实验.
No fire or
explosion
不起火
,
不爆炸
9.2
Over discharge
testing
过放测试
At 20
±
5
℃
,
According to the requirements of standard charge,
the cells will be discharge to cut-off voltage, then The
discharged cell is then subjected to a forced discharge at
constant current 1C to -4.2V. The total duration for the forced
discharge testing is 90 min.
在 20±5℃状态下, 按标准放电的要求放电至终止电压后,
然后以 1C 电流强制放电至-4.2V,持续强制放电 90 分钟
No fire or
explosion
不起火
,
不爆炸
9.3
Short-circuit
testing
短路测试
At 55
±
5
℃
, After standard charging, connect cells anode
and cathode by wire which impedance less than
80±20
m
Ω
,
The cell remains on test for 24 h or until the surface
temperature declines by 20 % of the maximum temperature
rise, whichever is the sooner.
在 55±5℃状态下,标准充电后,将电池的正负极用一根小
于 80±20mΩ的导线连接,放置 24 小时或电池显示温度是
最高温升的 20%。
