Abstract

The invention discloses a battery pack vibration durability test device, the battery pack vibration durability test device comprises a bottom plate, a support, a loading assembly and a clamping assembly, the support is detachably arranged on the bottom plate, one end of the loading assembly is detachably arranged on the support, and the other end of the loading assembly is detachably arranged on the clamping assembly. The clamping assembly is movably connected with the other end of the loading assembly, the clamping assembly comprises a first clamping part and a second clamping part, the first clamping part and the second clamping part respectively clamp the two ends of the battery pack, and the loading assembly is suitable for applying vibration to the battery pack according to a loading road spectrum so as to load the battery pack. Therefore, the vibration durability of the battery pack is tested. According to the vibration durability testing device for the battery pack, the vibration durability of the battery pack can be tested under the corrosion condition, so that the reliability of the battery pack is improved, and the vibration durability testing device is simple in structure and high in practicability.

Description

technical field [0001] The invention relates to the technical field of vibration fixtures, in particular to a battery pack vibration durability test device. Background technique [0002] At this stage, in order to attract users, major OEMs have made promises such as "5 years or 500,000 kilometers" and "lifetime warranty" for power battery cells. Close, and the vibration durability test of the battery pack is a short board in the industry. In order to meet the long-term warranty requirements of batteries, it is necessary to improve the durability and corrosion resistance of the power battery pack shell structure. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, an object of the present invention is to propose a battery pack vibration durability test device, which can test the vibration durability of the battery pack under corrosion conditions, thereby improving the rel...
