短路保护
After fully charging, the battery is short circuited through a
0.1Ω resistor for 1 h, then is charged at 1C for 5S. Checking
battery appearance.
电池完全充电后，将正负极用 0.1Ω电阻器短路 1h，将正负
极断开后，以 1C 电流瞬时充电 5S，目测电池外观
The battery should not explode,
catch fire, smoke or leak. The
battery voltage should not be lower
than 3.6v
电池应不爆炸,不起火,不冒烟或漏
液.电池电压应不低于 3.6V

PTC 保护验证
Short connected MOS tube of battery with PTC. After fully
charging, battery is put in the explosion-proof box and connected
with electronic load to be discharged at constant discharge current
of 8A. Checking current change of electronic load, and recording
the time from the beginning of discharge to the small current
(<1A). After current changes or the current does not change but
the discharge time reaches 60s, the test ends. 将带 PTC 电池的
MOS 管短接；将电池满充后，置于防爆箱中，连上电子负载，
设置 8A 的恒流放电电流，对电池进行放电，观察电子负载的
电流值变化，记录从开始放电到电流从 8A 变化到较小电流
（<1A）时的时间；电流变化后或者电流未变化但是放电时间
达到 60s 则实验结束。
The time from the start of
discharge to rapid current
change should be less than 60s.
要求从开始放电到电流突变的时间
应小于 60s。
