Drop 自由
跌落
Battery is charged according to the standard model and have
battery internal resistance and voltage measured. Within 1 h, drop
test should begins.The battery is drop form 1200 mm to marble or
steel plate. Each side of battery should be dropped 2 times. Then
it is stored after 2 h and have test voltage and internal resistance
measured. Finally, it is discharged at 0.2 C5 to cutoff voltage
电池标准充电后，测试电池的内阻及电压，1h 内开始自由跌落试验，
电池从 1200mm 高处自由跌落至大理石地板或者钢板上，6 个面各
着地 2 次，跌落完成电池搁置 2h 后，测试电压、内阻、将电池以
0.2C 电流放电至终止电压。
No obvious damage on the
surface, no crack, no swelling,
no leakage, no venting, no fire,
no explosion. Internal
resistance change be ≤ 10 m
Ω. Voltage change be ≤ 0.1
V. Discharge time≥4h.

滚跌落
After standard charging, battery is put aside for 1h and have
internal resistance and voltage measured. The height of drop is 1
m, speed is 5 RPM, and drop times is 50. After test is completed,
internal resistance and voltage of the battery are measured. It is
required that battery’s output is normal and can be charged and
discharged. Then barrel test continues. Drop times be no less than
200 times.
电池标准充电结束后，搁置 1h，测量电池的内阻、电压； 跌落高度
为 1 米，转速为 5 转/分钟，跌落次数为 50 次。试验完成后，再测量
电池组的内阻、电压。要求电池输出正常,能够充放电，然后继续翻
滚跌落试验, 跌落次数不小于 200 次。
After the test, the battery
function is normal, and the
battery structure does not
detached.
