Vibration Test

振动测试

Fixed the cell to vibration table and subjected to vibration cycling that the frequency is to be varied at the rate of 1Hz per minute between 10Hz an 55Hz, the excursion of the vibration is 1.6mm. The cell shall be vibrated for 30 minutes per axis of XYZ axes.

将电芯固定在振动台上,沿X、Y、Z三个方向各振动30分钟,振幅1.6mm,振动频率为10Hz~55Hz,每分钟变化1Hz。

3

Short circuit

(短路试验23±2℃)

Each test sample battery, in turn, is to be short-

circuited by connecting the (+) and (-) terminals of the battery with a Cu wire having a maximum resistance load of 0.1Ω.Tests are to be conducted at room temperature(23±2℃ ). (在常温下约23±2℃依次把每个样品电池的正负极用铜线连接起来使电池外部短路--线路总电阻不超过0.1Ω)

No explosion

无爆炸

No fire

无起火

4

Impact

(冲击试验)

A 56mm diameter bar is inlayed into the bottom of a 10kg weight. And the weight is to be dropped from a height of 1m onto a sample battery and then the bar will be across the center of the sample.(用一条直径为56mm的圆棒放置在电池中央,将一10Kg的重锤从1m的高度垂直落下在电池的中心位置)
