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 can be converted into electrical energy again. This type of battery is called a storage battery, also known as a secondary battery or lead-acid storage battery. The so-called storage battery is an electrochemical device that stores chemical energy and releases electrical energy when necessary.

[0003] The patent document with the announcement number CN218674153U discloses a battery pack test device, including a control module, a vibration table and a vibration device. The top of the vibration table is the mounting surface of the battery pack. The vibration device is mounted on the vibration table, and the control end of the control module is connected to the control end of the vibration device. The vibration of the battery used in the vehicle in daily life includes the ups and downs generated when the vehicle travels on the undulating road conditions and the impact of splashing pebbles, etc. The existing battery test device can generally only simulate the ups and downs, and cannot simulate the ups and downs and impacts at the same time, resulting in the test effect not matching the daily use; and the existing battery test device generally adjusts the vibration amplitude by modifying the programming, and the vibration amplitude is unstable, which reduces the user experience of the test device. Summary of the invention
