Abstract

The invention discloses a battery pack and a vehicle with same. The battery pack comprises a box body; a cover body, wherein the box body is covered with the cover body, so that a containing space isdefined between the box body and the cover body; a battery module which is arranged in the accommodating space; wherein the cover body is provided with an anti-vibration piece, and the anti-vibrationpiece is at least arranged at the maximum vibration mode area of the cover body. According to the battery pack disclosed by the invention, the anti-vibration part is at least arranged in the area withthe maximum vibration mode of the cover body, so that the first-order mode of the cover body is improved, the amplitude and abnormal sound of the cover body are reduced, the shape of the cover body is not changed, and the air tightness of the battery pack is not influenced.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a battery pack and a vehicle with the same. Background technique [0002] In related technologies, during the driving process of the whole vehicle, the excitation vibration caused by unbalanced wheels and uneven road surface generally has a frequency between 1-30 Hz. And when the vehicle speed is less than 150km / h, the excitation frequency caused by the unbalanced wheel is less than 21Hz. When the frequency of the external exciting force is close to the first-order natural frequency of the battery pack, the battery pack system will resonate, which increases the frequency of failures of the battery pack system. In order to avoid resonance during vehicle driving, the first-order natural frequency of the battery pack needs to be controlled above 35Hz. [0003] Because the first-order mode and vibration shape of the battery pack system are mostly on the box cover, when the first-...
