The new BMW iX3 - How the BMW Group builds its high-voltage batteries for Gen6

The BMW Group sources battery cells for its high-voltage batteries from leading cell manufacturers, which produce them according to the company's specifications. The highest technical requirements apply. In the BMW Group's high-voltage battery assembly plants, cell clustering takes place, where the battery cells are connected to coolers. Cell clusters and cell contacting systems are cleaned and precisely welded by laser. An innovative foam process now ensures that all elements become a mechanical unit and are protected. The foam guarantees the safety, stability, and longevity of the high-voltage battery. Subsequently, the housing is closed, and in the final assembly step, the Energy Master is installed on the high-voltage battery. Finally, all high-voltage batteries undergo a 100% end-of-line test to ensure quality, safety, and functionality.
