The utility model relates to the technical field of battery pack safety performance detection equipment, and provides a battery pack bottom ball strike test device, which comprises an electromagnetic driving assembly, the electromagnetic driving assembly comprises a ball strike head, a magnet, homonymous electromagnets arranged along the circumferential direction of the magnet and a mounting seat, the magnet is arranged on the mounting seat, and the ball strike head is arranged at the top end of the magnet. And after being electrified, the same-name electromagnets generate repulsive force with the magnets to drive the ball hitting heads to move towards the bottom of the battery pack. The ball hitting head is arranged at the top end of the magnet, the magnet is arranged on the mounting seat, the same-name electromagnets are arranged in the circumferential direction of the magnet, the same-name electromagnets generate magnetism repellent to the magnetism of the magnet after being electrified, and the magnet dri
