Impact test requirements
Secure the entire fitting surface of each cell and battery sample with a stable bracket.
The battery is attached to the test machine by a mounting bracket that supports all surfaces. Each battery was subjected to a total of 3 collisions of the same magnitude. Collisions occur in three mutually perpendicular directions, except that there are only two axes of symmetry, and only two directions are collided. Each collision occurs in one direction perpendicular to the surface of the battery. The battery has a minimum average acceleration of 75 g (g is the acceleration due to gravity) every 3 mS initially. The peak acceleration should be between 125g and 175g. The test was carried out at an ambient temperature of 20 ° C ± 5 ° C.
After the battery is fully charged according to the charging procedure specified by the manufacturer, it is fastened to the impact table for a half sine pulse impact test. In the first 3 ms, the minimum average acceleration was 75 gn, the peak acceleration was 150 gn ± 25 gn, and the pulse duration was 6 ms ± 1 ms. Three acceleration shock tests were performed from every three directions.
After the battery is fully charged according to the manufacturer's charging procedure, the surface of all the components of each cell and battery sample is held in a stable bracket. Three impacts were applied in each direction of the three mutually perpendicular mounting positions of the battery for a total of 18 impacts. Each impact is a half-sinusoidal acceleration with a peak of 150 gn, and the pulse lasts for 6 ms.
