AI Technical Summary
Technical Problem
After the module structure is eliminated, the structural strength of the CTP battery pack is reduced, resulting in greater force on the cells, poorer safety performance, and higher requirements for the strength of the cell casing.
Method used
A reinforcing beam is added to the connecting beam of the first housing, making it detachably connected to the connecting beam and the second housing to form mechanical protection and improve the overall strength and safety performance of the battery pack.
Benefits of technology
By strengthening the beam design, the stress on the cells under collision or compression is effectively reduced, improving the safety performance and mechanical strength of the CTP battery pack, while not occupying cell space and ensuring energy density.

Abstract
This utility model belongs to the field of battery technology and discloses a CTP battery pack. The CTP battery pack includes a first shell, a cell assembly, a second shell, and reinforcing beams. The first shell contains several connecting beams that divide its cavity into multiple receiving chambers; each receiving chamber contains at least one cell assembly. The second shell covers the first shell. At least one reinforcing beam has a connecting beam, with its first end detachably connected to the connecting beam and its second end detachably connected to the second shell. By adding reinforcing beams to the connecting beams within the first shell, the CTP battery pack achieves both the function of separating the cell assemblies and, in conjunction with the reinforcing beams, improving the overall strength of the battery pack. Therefore, it improves the safety performance of the CTP battery pack without occupying cell space, effectively ensuring the energy density of the CTP battery pack.
