The Making of BYD Cars
BYD's manufacturing process is characterized by vertical integration, allowing the company to control every aspect of production—from battery development to vehicle assembly. This approach enhances efficiency and quality control.
The company's Blade battery, introduced in 2020, features a unique design that improves safety and energy density. Unlike traditional cylindrical cells, the Blade battery's flat, elongated structure allows for better heat dissipation and space utilization.
