Low pressure
低气压
After standard charging, the battery was placed in a vacuum box
at an ambient temperature of 23℃±2℃. After the box was closed,
the internal pressure was gradually reduced to no more than
11.6kpa. Battery is stored in such environment for 6h. Then it is
taken out to be placed in an open circuit for 1h. (simulated altitude
of 15240m)
电池标准充电结束后，在 23℃±2℃的环境温度下，将其搁置在真空
箱中，真空箱密闭后，逐渐减少其内部压力至不高于 11.6kPa，开路
放置 6h（模拟海拔 15240m），然后取出电池，开路搁置 1h，观察电
池状态。

高温存储
After standard charging, the battery is stored for 2h, and have
thickness measured. Under the condition of 70℃±2℃, the battery
is stored for 16h. Then, the battery was taken out to be stored for
2h. Battery thickness is measured. Finally, the battery is charge
and discharge at 0.2c current for 1 time. Recording discharge
time.
电池标准充电结束后，开路搁置 2h，测量厚度；在 70℃±2℃的条

Temperature
cycle
温度循环
The standardly charged battery was shelved at 75℃±2℃ for 6h. Then,
after temperature was reduced to -40℃±2℃ within 30min, it is stored
for 6h. This was a cycle. After 10 cycles, the battery was shelved for 1h
at 25℃±2℃. 电池按标准充电结束后，放入冷热冲击箱中，电池在
75℃±2℃中搁置 6h，然后在 30min 内将温度降至-40℃±2℃并恒温
6h，如此为 1 个循环，共循环 10 次，试验结束后在 25℃±2℃环境
温度下将电池搁置 1h 进行检测
Battery should not leak,
vent, crack, catch fire, or
explode.
要求电池应不泄露，不泄气，
不破裂、不起火，不爆炸。
Salt spray
test
盐雾试验
The battery terminals were placed in the salt spray test box with
35℃±2℃, humidity ≥ 85% and PH value within 6.5 ~ 7.2. Its
surface was sprayed with mist produced by 5% ± 1% NaCl
solution for 48 hours. Checking battery surface.
将电池端子放入35℃±2℃、湿度≥85％、PH值在6.5～7.2范围内
的盐雾试验箱中，用5％±1％的NaCl溶液盐水喷雾，持续48h，检

Vibration
test
振动测试
After the battery is fully charged according to the standard
charging mode, the voltage and internal resistance of the battery
are measured. The battery was fixed on the vibration table for
vibration test within 1h. The battery was subjected to vibration
with frequency of 10-60hz, amplitude of 1.6mm and frequency
sweep rate of 1oct/min. The frequency was swept for 30min in the
directions of X, Y and Z. Measuring voltage, internal resistance
and residual capacity of the battery after the frequency sweep.
