Vibration
|
After standard charge, the battery is to be tested as following conditions:
Amplitude: 0.8mm
Frequency: 10~55Hz(sweep: 1Hz/min)
Direction: X/Y/Z axis for 90~100min. The battery is to be tested in three mutually perpendicular to each axis.
|
No fire, no explosion, no smoking is obtained
|
||
|
Short Circuit Test
|
After standard charge, the battery is to be short-circuited by connecting the positive and negative terminals of the battery with copper wire having a maximum resistance load of 0.1Ω.
|
No explosion, no fire. The temperature of the exterior cell casing shall not exceed 130°C
|
||
|
Drop Test
|
Drop the battery in the shipment condition(full-charge) from 1m height onto 5cm or thicker concrete with p-tile on it 3 times each of X, Y, and Z directions at 25±20C.
|
No fire, no explosion, no smoking is obtained.
