[0002] A device that converts chemical energy into electrical energy is called a chemical battery, generally referred to as a battery. After discharge, the internal active substances can be regenerated by charging to store electrical energy as chemical energy. When discharge is required, the chemical energy is converted into electrical energy again. This type of battery is called a storage battery, also known as a secondary battery or lead-acid battery. The so-called storage battery is an electrochemical device that stores chemical energy and releases electrical energy when necessary.

[0003] Patent document CN218674153U discloses a battery pack testing device comprising a control module, a vibration table, and a vibration device. The top of the vibration table serves as the mounting surface for the battery pack, and the vibration device is mounted on the vibration table. The control terminal of the control module is connected to the control terminal of the vibration device. The vibrations experienced by vehicle batteries in daily life include the ups and downs caused by the vehicle traveling on bumpy roads and the impact of flying pebbles. Existing battery testing devices generally only simulate ups and downs, but not both ups and downs and impacts simultaneously, resulting in test results that are inconsistent with daily use. Furthermore, existing battery testing devices generally adjust the vibration amplitude through programming modifications, resulting in unstable vibration amplitudes and a reduced user experience. Summary of the Invention

[0044] This embodiment also discloses a battery testing method, comprising the following steps:

[0045] Step 1: Place the battery to be tested inside the battery frame 2 and securely connect it to the battery frame 2. Then, rotate the screw push block 44 outward to release the pressure of the clamping plate 45 on the connecting disk 41, loosen the limiting column 43, adjust the radial position of the limiting column 43, and then rotate the screw push block 44 inward to push the clamping plate 45 to clamp the connecting disk 41, thereby clamping the limiting column 43. Then, install the release plate 85 at the set position on the vibration frame 54.

[0046] Step 2: Start the drive motor 32, which drives the connecting plate 41 to rotate.

At this time, the impact plate 61 continues to be stuck under the fixed block 83, and the second spring stores force for the rebound of the impact plate 61; when the release plate 85 reaches the second guide surface 842, the fixed block 83 breaks contact with the impact plate 61, and the elastic force of the second spring is released, pushing the impact plate 61 to rebound upward and impact the battery through the impact column 63; when the release plate 85 reaches the second guide surface 842, the push-down plate 72 reaches the first inclined surface 711 and is pulled back under the action of the third spring 74, and will not hinder the impact plate 61.
