Abstract: This article implements the design and application of an electric vehicle load power control system based on the actual situation in Yunnan. The system has designed data integration and error prevention strategies, ensuring that the system has fault-tolerant ability in actual situations and improving system reliability. Based on the future development of charging loads, this system can be expanded into a layered and partitioned control system with strong scalability. At present, the system has been deployed and applied, and the effectiveness is yet to be verified.
