Abstract

The present invention relates to an impact testing device for a battery pack. The device comprises a collision barrier used for placing the battery pack, a movable sliding table with an impact head, a hydraulic power device used for pushing the movable sliding table to slide, and a monitoring device in communication connection with a sensor inside the battery pack. The movable sliding table is positioned between the hydraulic power device and the collision barrier. The impact head of the movable sliding table is oriented towards a support assembly for placing the battery pack and positioned on the side surface of the collision barrier. The monitoring device controls the starting and the stopping of the hydraulic power device. The device further comprises a solution tank positioned right below the support assembly and used for the fire extinguishing of the battery pack. The monitoring device also controls the support assembly to release the battery pack so as to enable the battery pack to fall into the solution tank. According to the technical scheme of the invention, the fire extinguishing problem of the battery pack during the impact test in the prior art can be solved.

Description

technical field [0001] The invention relates to the field of electric vehicle battery collision safety performance testing, in particular to a battery pack impact testing device. Background technique [0002] With the increase in sales of electric vehicles, accidents of short-circuit fires caused by mechanical damage to batteries of electric vehicles occur from time to time.
