The Baotou BYD Cleaning Room and Air Conditioning System Project is located in the newly planned area of the Equipment Manufacturing Industrial Park in Baotou, Inner Mongolia. With a construction area of 68,000 square meters, it serves as a crucial link in constructing the BYD blade battery industry chain and represents BYD's first large-scale lithium battery ultra-thin copper foil production project in the autonomous region. The project aims to meet the production demand for 30 GWh of blade batteries. Upon completion, the project will establish Baotou's Qingshan District as an important base for BYD's copper foil production. The construction scope includes clean decoration, ventilation, lighting and power, heating, chilled water, cooling water, insulation, secondary steel structure, and automatic control engineering.
