Abstract: The present invention relates to the field of batteries, and particularly to a device and method for mechanical abuse testing of batteries. Existing devices apply compression vertically to the battery's force-bearing surface, which does not adequately simulate complex mechanical abuse during tilted scenarios. Specifically, they cannot compress the battery at multiple angles or collect compressive force values from different orientations. The invention provides an adjustable-tilt compression device for mechanical abuse testing of lithium-ion batteries. By tilting the battery support plate of the fixture, the device enables multi-angle compression and collection of force data from various angles, allowing for comprehensive testing of mechanical stresses encountered in real-world tilted abuse conditions. Additionally, the device supports testing at multiple points and under varying temperatures, enhancing the reliability and coverage of mechanical abuse assessments for battery safety evaluation.
