New energy three electric system lightweighting potential is huge, battery box lightweighting is the incremental field. In the three electric systems of new energy vehicles, the battery pack is the largest part of the weight, accounting for about 18%-20% of the weight of the whole vehicle, of which the battery shell accounts for about 10%-20% of the weight of the battery pack, which is the component of the battery pack that is second only to the electric cell in terms of weight. After the battery energy density has gradually entered the bottleneck period, the battery shell lightweighting has become a key area for new energy vehicles.
Therefore, as the penetration rate of new energy vehicles continues to rise, the lightweight battery box that meets all safety performance requirements is a new incremental market, which becomes an excellent development opportunity for integrated die-casting. The current battery box production process is less efficient, integrated die-casting is expected to release the battery box capacity bottleneck. With the continuous breakthrough of large tonnage die-casting machine technology and new aluminum alloy material, integrated die-casting technology is expected to produce battery boxes that meet the safety performance requirements.
