Tesla Model 3 & Y
Model 3/Y Assembly Process
Battery Pack Integration: CATL cells from Lingang, Fuding, Liyang, Yibin, and Ningde flow into Tesla’s Shanghai pack lines, where modules, cooling plates, BMS boards, and structural pack casings are integrated into chassis-ready units.
Body & Chassis: Stamping, gigapress mega-casting, laser welding, panel bonding, corrosion coating, and subframe assembly take place in the main body shop with inputs from aluminium billet suppliers, die-casting materials, and structural adhesives.
Power Electronics: SiC inverters from Wuhan and Shaoxing feed the drive-unit line along with DC-DC converters, onboard chargers, gate-driver boards, and MOSFET modules from suppliers in Hefei, Suzhou, and Wuxi.
Final Assembly: More than 60 suppliers provide interiors, wiring harnesses, glass, seats, infotainment modules, suspension parts, tires, thermal-management systems, and ADAS sensors, all converging into GA3/GA4 for final vehicle build.
