Discharge capacity 50% of initial capacity
No explosion, no fire, no leakage. Discharging capacity 60% of initial capacity
5. Mechanical performance
No Items 1 Vibration
Test
2 Drop Test
Test Method
After standard charge, the cell is installed onto the vibration desk with clamps. The test is to be varied at the rate of 1oct/min between 10 and 55Hz. Repeat vibration for 30min in three mutually perpendicular directions. Equipment parameters of frequency and amplitude are as follows: Vibration frequency: 10-30Hz, amplitude: 0.38mm; 30-55Hz, amplitude: 0.19mm After standard charge, the cell is dropped from a height of 1m to a concrete surface. Each cell is to be dropped once in the positive and negative directions of three mutually perpendicular mounting positions for a total of 6 times, then rest for 1 hrs.
Criteria No scratch, no leakage, no fume, no explosion. Cell voltage 3.2V
No leakage, no fume, no explosion
