[0003] With the rapid development of new energy vehicles, new energy vehicle models are constantly being developed, passenger vehicles are becoming increasingly mature, and commercial vehicles are also being promoted and implemented. However, compared to passenger vehicles, commercial vehicles have a greater demand for battery power. Moreover, commercial vehicle models are generally longer. With the increasing power consumption, the space for width expansion is limited. This can only be achieved by increasing the energy density of battery cells or lengthening the battery pack. Increasing the energy density of battery cells is not something that can be achieved overnight. Given the urgent needs, increasing the length is inevitable. As the length of the battery pack increases, the size of the vibration table is required. However, existing laboratory vibration tables are commonly used for passenger car battery packs. In comparison, there are fewer vibration tables suitable for commercial vehicle battery packs, which limits the practical options.
