Technical Field

[0001] This disclosure relates to the field of new energy vehicle technology, and in particular to a battery pack housing structure. Background Technology

[0002] With the development of new energy electric vehicle technology in my country, the market share is gradually increasing. At the same time, users are demanding higher performance and safety from electric vehicles. However, electric vehicles may be subject to collisions during operation. As a crucial component of the vehicle, the battery pack's casing structure must be sufficiently robust to protect the internal battery cells from physical damage, prevent short circuits or leaks, and ensure passenger safety. The connection structure between the battery pack and the vehicle is susceptible to damage during operation. Replacing materials and increasing material thickness would inevitably increase the cost of the battery pack, leading to an increase in the overall vehicle cost and hindering market competitiveness.
