TREE NEWS update: BMW Group began trial production of its energy control system at its powertrain plant in Shenyang on September 22. The move means all core elements of its sixth-generation power battery — technology R&D, component supply, cell manufacturing, and battery pack and energy control system production — will be fully localized in China.
BMW Starts Trial Production of Energy Control System in Shenyang, Localizing Gen-6 Battery Core Tech in China
The significance is less about BMW's battery chemistry than about where the value chain sits: bringing energy-control production in-house at Shenyang puts the last major piece of the Gen-6 system inside China, alongside R&D, component supply, cell making and pack assembly. That concentrates both cost control and supply-chain resilience in one market, which matters for how the company's EV economics and export flexibility are managed from here. The open question is whether this localization extends to models built for other markets, or stays a China-only arrangement.
