The battery pack drop test bench was subjected to a vertical impact test on the test piece by means of free fall. The test piece can be freely selected from the three states of face, edge and angle for the drop test, and the drop test height can be preset in advance. The positioning stops automatically when the test piece is raised to the preset height. The distance between the test arms can be selected according to the different size of the product, and the electric width can be adjusted. The test machine release mechanism is free, flexible and reliable, ensuring that the test piece is not affected by any external force during the release moment and free fall, thus ensuring the required drop state of the test piece.
