CATL, China’s largest battery supplier for electric vehicles, will license technology for integrating battery cells directly into packs to Hyundai Mobis, the auto parts unit of Hyundai Motor Group.
Under a letter of intent signed Wednesday, Hyundai Mobis will use the supplier’s patented “cell-to-pack” technology to build battery units for Korean and global markets, CATL said.
By integrating cells directly into battery packs rather than modules, the energy density of battery packs can be increased while simplifying manufacturing and saving costs, it added.
CATL introduced the “cell-to-pack” technology at the Frankfurt auto show in 2019.
By eliminating module assembly, the technology could improve volume utilization efficiency by 15-20 percent, raise energy density by 10-15 percent, and cut the number of parts by 40 percent for battery packs, CATL said at the time.
