DSP-Based Centralized Orderly Charging Control System Balances Grid Stability and EV Charging Demand

The Grid Challenge Behind Mass EV Adoption

As urbanization and industrialization accelerate, the widespread adoption of electric vehicles has opened new pathways for solving environmental and energy challenges. However, large-scale EV charging behavior presents significant challenges for charging operation management and power grid security. Uncontrolled, disorderly charging inevitably leads to peak load superposition on the grid, increasing peak-valley differences and negatively impacting safe grid operation.

Recognizing this critical issue, the Tenglong Automotive engineering team has developed a DSP-based centralized orderly charging control system that integrates vehicle, charging post, parking space, and grid management into a unified solution.

Engineering Excellence: DSP-Powered Intelligence

This project leverages the superior computational speed, rich internal resources, and fast communication capabilities of the Digital Signal Processor as the core control chip. The system architecture is built around four functional modules:

▪ Data Processing Module: Handles real-time collection and analysis of charging data

▪ Analysis & Computation Module: Executes orderly charging algorithms based on grid load conditions

▪ Monitoring & Display Module: Built with MFC technology to create a multifunctional monitoring and management client

▪ Offline Processing Module: Ensures system continuity during network interruptions

Seamless Data Integration and Communication

The system utilizes Socket technology and JSON markup language for robust data interaction design. This approach enables reliable communication between charging infrastructure, vehicles, and the central control system, supporting real-time decision-making for orderly charging management.

Key Innovations for Grid-Friendly Charging

1. Vehicle-Post-Space-Grid Integration: The system achieves integrated orderly charging management across all four elements, enabling centralized control that improves overall EV charging efficiency while maintaining grid security.

2. User Experience and Cost Efficiency: By optimizing charging schedules based on grid conditions, the system meets user charging demands while reducing operational costs, delivering measurable economic benefits for production and fleet operations.

3. High-Low Level Control with Reduced Switching Loss: The system employs high-low level control strategies that minimize switching losses while maintaining excellent balanced charging performance, extending component life and improving energy efficiency.

Proven Results and Intellectual Property

The project has successfully been granted a software copyright: "Automotive New Energy Centralized Charging Control System". The system includes comprehensive EV charging data management with automatic data backup and recovery capabilities, eliminating concerns about data loss.

Commitment to Smart Charging Infrastructure

This project underscores Xiangyang Tenglong Automotive's commitment to holistic energy management solutions. By integrating this DSP-based orderly charging control system into our production processes and vehicle lineup, we significantly improve charging efficiency during manufacturing while reducing costs. More broadly, the system provides a scalable model for charging infrastructure operators seeking to balance user demand with grid stability.
