Jiaozuo is an important node city in the northwest of Henan Province and the southeast of Shanxi Province, and a vital corridor for the transportation of coal from Shanxi to other regions, with nearly 20,000 heavy trucks passing through daily. To continuously meet the charging needs of electric heavy trucks, State Grid Jiaozuo Power Supply Company actively provides power connection and related services for transportation companies' electric heavy trucks charging stations, and promotes the implementation of its own charging station projects. Focusing on the charging needs of new energy heavy trucks, it has adopted flexible and efficient modular substations to effectively support the load requirements of charging facilities.
Currently, a total of 182 new energy heavy truck charging stations have been built across Jiaozuo, with a power supply capacity of 359,600 kVA. The heavy truck charging points have formed a 15-minute service circle in local coal logistics parks and main urban-rural freight lines, achieving precise matching of charging and battery swapping infrastructure with transportation needs. State Grid Jiaozuo Power Supply Company has been empowering rural logistics development with reliable power, injecting strong momentum into rural revitalization.
