[0003] As the core component of new energy vehicles, after the new energy vehicle batteries are produced by manufacturers, the battery packs need to be transported. The top priority for meeting the battery transportation requirements is safety. Therefore, the design of the battery pack packaging must comply with the applicable regulations for its intended transportation, which is crucial. Currently, in the industry, the packaging of battery packs mostly uses sealed wooden packaging boxes, which are mainly composed of multiple wooden boards connected together, and waterproof paper and waterproof plastic films are arranged inside. Then, the battery packs to be transported are installed in the wooden boxes and limited and fixed. When assembling the wooden packaging boxes, tools such as nails and hammers are required, the installation operation time is long, the operation is not convenient enough, and the efficiency is low. In addition, after the wooden packaging boxes are discarded, their materials are not easy to recycle and reuse. In addition, some use EPS materials as buffers inside the box. Since EPS materials are difficult to degrade and are restricted in use by some countries, it affects the export business of new energy vehicle batteries in our country. This makes it necessary in the market to have a packaging method using degradable buffer materials to replace the original packaging. At the same time, in order to maintain the integrity of the surface of the packaged batteries, it is best to keep a certain space distance between each battery after packaging.
