Where does the Mach-E battery come from?
The battery cells in the Ford Mustang Mach-E come from multiple suppliers and are assembled into packs by specialized partners as part of Ford’s broader electric-vehicle supply chain. The exact source can vary by model year and region, with emphasis on a diversification strategy that Ford has pursued in collaboration with its battery partners.
Key sources of Mach-E battery cells
The following list identifies the two primary cell suppliers Ford has used for the Mach-E and how they fit into the supply chain.
- LG Energy Solution (LGES) — A main supplier of lithium‑ion cells for Mach-E models, with cells produced in LGES facilities in Korea and the United States. These cells are used to form the energy packs installed in various Mach-E trims and configurations.
- SK On — Ford’s BlueOval SK joint venture with SK On provides additional cell supply for current and upcoming vehicles, including Mach-E variants. This arrangement is part of Ford’s strategy to diversify suppliers and secure domestic battery cell production through a U.S.–based operation.
In short, the Mach-E’s cell supply comes from LG Energy Solution and SK On, with the exact source depending on model year, region, and the evolving supplier mix Ford has pursued through its partnerships.
Battery pack assembly and integration
The following overview explains how the cells are turned into the packs that power the Mach-E and how those packs are integrated into the vehicle during production.
- Pack modules are assembled by contract manufacturers using cells supplied by LGES or SK On, following the design and specifications specified by Ford and the cell makers. This includes formatting the cells into modules and shaping the complete battery pack for the Mach-E’s layout and performance targets.
- The finished battery packs are then integrated into the Mach-E during final vehicle assembly at North American plants, where the battery system is mounted and connected as part of the overall vehicle build.
This arrangement—cell supply from major partners combined with third-party pack assembly and Ford’s final-assembly integration—helps Ford manage supply risks while scaling production across regions.
What this means for customers
Understanding the sourcing and assembly path of the Mach-E’s battery sheds light on several practical implications for buyers and owners.
- Supply diversification can influence model availability and production timing, as shifts in cell supply may affect when specific trims are ready for sale.
- Battery pricing, warranty considerations, and long-term performance can be affected by the choice of cell supplier and the evolution of pack technology within Ford’s BlueOval SK program.
- Ford’s ongoing battery strategy, including BlueOval SK’s U.S. facilities, aims to improve domestic cell production and supply resilience for Mach-E and other future EVs.
Overall, Ford’s battery sourcing strategy for the Mach-E reflects a concentrated effort to diversify suppliers, pursue domestic manufacturing, and align with broader plans to scale EV capacity in North America.
Summary
The Mach-E’s battery comes primarily from LG Energy Solution and SK On, with the exact mix varying by year and region as Ford diversifies its supply chain. Battery packs are assembled by contract manufacturers and installed at Ford’s North American assembly plants, reflecting a global yet regionally tailored approach to electrified vehicle production. This strategy positions the Mach-E within Ford’s broader push to stabilize battery supply and boost domestic production through the BlueOval SK partnership.
