Description

Technical Field

[0001] The utility model relates to the field of battery pack testing, in particular to high-performance battery pack testing equipment. Background Art

[0002] Electric vehicles are currently the predominant type of new energy vehicle. With the growth of electric vehicle sales, accidents involving short circuits and fires caused by mechanical damage to batteries are becoming more common. To improve the safety of electric vehicle batteries, most electric vehicle manufacturers use simulated crash testing equipment to subject batteries to impact and collisions, providing a direct understanding of battery safety performance.

[0003] Existing automotive battery impact tests require repeated impacts on the battery to test its impact resistance. During the test, multiple groups of batteries often need to be tested and compared to ensure the accuracy of the test data.

[0004] A Chinese utility model patent with announcement number CN115435997B discloses a new energy vehicle battery impact resistance testing device. This utility model realizes impact testing by rolling up an impact hammer by connecting a rope to different heights. However, this utility model can only meet the impact test of a single impact hammer and cannot meet the simultaneous impact test of multiple impact hammers. Therefore, it is urgently needed to be improved. Utility Model Content
