After the battery is fully charged according to the test method of 4.5.1, install the battery on the surface of the platform, place a metal bar with a diameter of 1.58mm±0.2mm on the upper surface of the geometric center of the battery, and use a weight with a mass of 9.1kg±0.1kg to impact the surface of the battery with the metal bar from a height of 610mm±25mm in free fall. And observe for 6 hours.
1, automatic lifting weight, and adjust to the required height automatically stop.
2, according to the test automatic drop hammer to complete the test.
3, the box body adopts double layer protection function.
4, inner box exhaust fan, high temperature explosion-proof light.
