Heavy impact test requirements
Impact (for cylindrical batteries with a diameter of not less than 18 mm)
The battery was tested at an ambient temperature of 20 ° C ± 5 ° C. The test sample was placed on a flat surface. A strip of 15.8 mm ± 0.1 mm diameter was placed in the center of the sample. An object weighing 9.1 Kg ± 0.46 Kg dropped from the height of 610 mm ± 25 mm and hit the battery.
After the battery is fully charged in accordance with the test method specified in 4.5.1, place the battery on the surface of the platform, and place a metal rod with a diameter of 15.8 mm ± 0.2 mm on the upper surface of the geometric center of the battery, and use a mass of 9.1 kg ± 0.1 kg The heavy object hits the surface of the battery with the metal rod in the free fall state from a height of 610 mm ± 25 mm, and observes for 6 hours.
The cylindrical battery is required to have its longitudinal axis parallel to the surface of the heavy object during the impact test, and the metal rod is perpendicular to the battery’s longitudinal axis. The square battery is only impact tested on the wide surface. When the button cell is subjected to an impact test, the metal rod is placed across the center of the cell surface. Only one impact test is done for one sample.
The battery should not catch fire or explode.
Note: For flexible packaging batteries, this article does not apply.
The battery sample was placed on a flat surface and a 15.8 mm diameter cast strip was placed in the center of the sample. An object weighing 9.1 Kg was dropped from the height of 610 mm ± 25 mm to the battery and allowed to stand.
