The vehicle production area for the manufacture of the EVs is 1 million square meters (going to 2 million) and consists of five workshops: Stamping, Welding, Painting, Final Assembly, and Battery Pack production.
The Industry 4.0-compliant plant staff includes 600 personnel. Of the engineers there, 74% have 5+ years’ experience and 78% joined from other OEMs.
He Xiaopeng, Chairman and CEO of Xpeng Motors, said, “We are a firm believer that manufacturing is the foundation of smart cars. Only when you build solid powertrain and vehicle hardware, can you differentiate with data operation, autonomous driving and connectivity software.”
Stamping
- 100% automated
- Features a 6,600-ton stamping line
- Produces up to 12 pieces per minute
- Parts produced with a precision of 0.1 mm
Welding
- Equipped with 210 ABB industrial robots (there are a total of 264 robots throughout the manufacturing complex)
- In addition to welding, gluing and aluminum plate riveting are performed
- Vehicle bodies are steel and aluminum
- Welding machines are adaptive to provide as much as 30% energy savings
Painting
- Thin-film pretreatment and cathode electrophoretic tech reduces wastewater discharge, slag yield (down 94%), energy consumption (down 25%)
- Zero heavy metal emissions
- Uses BASF high-throwing powder coat and B1B2+2K water-based varnish, double-layer paint
Assembly
- Highly automated with AGVs and robots
- Digital system assures all fasteners have the proper torque
Battery Pack
- AGV-based production line
- Robotic assembly
- Each battery pack undergoes 198 offline tests and 89 performance tests
