With the high-quality and rapid development of the new energy vehicle industry in the past two years, battery PACK technology has also been hailed as the fifth largest technology in automobile manufacturing by the industry. As an important part of the battery pack, the new energy battery tray, its design, material selection and manufacturing process have attracted the attention of the industry chain!

New battery trays need to balance weight, safety, cost, material properties and more! According to relevant experts: in the future, with the continuous control of car manufacturing costs, there will be a demand for steel pallets to climb; steel-aluminum mixed material pallets are also used in Tesla, Lantu, BAIC and other models; Alloy battery tray is still the mainstream solution in the market!

There are currently two main process routes for aluminum alloy battery trays: one is extrusion profile welding, which is currently used by many OEMs, and the product has the advantage of good structural strength; the other is integrated die-casting + skin welding. The advantage of this scheme is higher efficiency.
