1. Application of platform-based general concepts in the R&D process

During the research and development process, the platform-based universal concept was widely used to reduce costs and improve the development cycle. For example, by using the body frame and panels to replace the battery pack cover, not only the space is optimized, but also lightweight, although this increases the test of sealing. In order to further optimize the structure and achieve better integration and lightweight effects, cast aluminum torsion boxes and hot-formed beam frame aluminum are used, which requires new cold connection processes such as screw connection, FDS and SPR.
