Description

Module-free box-in pressure-maintaining integrated device

Technical Field

The utility model relates to the technical field of lithium battery manufacturing, in particular to a module-free box-in pressure-maintaining integrated device.

Background

The module structure form of the battery pack is always an impetus for innovation and development of new energy power batteries. CTP technology (no module technology) proposes skipping corresponding out-of-box forming module forms on the MIP legacy battery pack structure; the traditional out-of-box forming module form can be omitted, because the CTP technology can reduce the huge volume weight of the battery pack, wherein the internal wiring harness and the structural members are correspondingly reduced, the service efficiency of the battery cell can be greatly improved, and the energy density of the whole battery pack is greatly improved. The method can reduce the corresponding cost, improve the space utilization rate of the battery pack, and improve the safety of the battery pack.
