Description

Technical Field

[0001] The utility model relates to the technical field of battery pack testing, in particular to a battery pack immersion testing device. Background Art

[0002] New energy vehicles use batteries to provide kinetic energy. After the new energy battery pack is produced and processed, in order to ensure its quality, it is necessary to test the new energy battery pack, and then it is necessary to use corresponding testing equipment. There are many types of testing equipment, including water immersion testing equipment for new energy vehicle battery packs.
