Gravity Impact Tester for Lithium Ion Batteries Free Fall Test

Gravity Impact Tester for Lithium Ion Batteries Free Fall Test


The gravity impact tester is used to simulate the cell phone during or before the battery is installed, The force of impact a battery can withstand. Whether the battery will explode and catch fire after impact. The gravity impact test machine is a good way to evaluate the safety of the battery. Gravity impact tester from Wewon Environmental Chambers Co., Ltd. comply with UN 38.3.4.6, IEC 62133, UL 1642, UL 2054 & IEC 60068-4:2000.Get more news about Battery Heavy Impact Tester,you can vist our website!

How to use the gravity impact tester ? The lithium ion battery gravity impact tester is tested by placing the battery sample on a flat surface. Cross a rod with a diameter of 15.8 mm and place it in the center of the sample, A weight of 9.1 kg or 10 kg was used to fall from a certain height (610 mm or 1000 mm) onto the sample. Observe and evaluate the performance and safety of the battery tested by free fall test.

The cylindrical or prismatic cell shall have its longitudinal axis parallel to the plane and perpendicular to the center of the horizontal specimen so that the curved body longitudinal bearing with a diameter of 7.9 mm shall be impacted. The prismatic cell is also rotated 90° around its vertical axis so that its wide and narrow sides can withstand impact.
Each sample battery should withstand only one shock, and each test should use different samples. Coin-type or button-type battery shall make the surface of the test sample parallel to the plane. The curved body with a diameter of 7.9 mm lies across the center of the battery.
