Our company promotes the coordinated development of upstream and downstream industries, and uses independently developed high-strength steel in heavy-duty truck manufacturing. The ultra-low emission clean transportation transformation project is implemented in two phases, purchasing and updating 100 vehicles, including 39 new energy vehicles, and supporting the construction of battery swap stations, charging piles and other infrastructure. The newly built electric heavy-duty truck battery swap station is the first new energy battery swap station. The station is equipped with 8 bays and 7 spare batteries, which can match 87% of domestic OEM vehicle battery swaps. After the project is completed, carbon dioxide emissions can be reduced by about 7,000 tons per year.
