Abstract: This paper aims to realize the visualization of energy flow ratio, quantitative analysis of power consumption, matching verification of key systems and comparative analysis with competitors. Through directional collection, real-time data calculation, integral processing, dynamic data fitting and cluster analysis technology, the voltage, current, temperature, controller area network (CAN) message and global positioning system (GPS) data of new energy vehicles are visualized. By quantifying the vehicle's energy flow and distribution, the effectiveness of strategy optimization is evaluated, and performance parameters are adjusted accordingly to enhance overall efficiency. This study contributes to enhancing the energy consumption advantages of pure electric light trucks and their adaptability under complex road conditions, which is significant for maintaining a competitive market advantage. A set of methods for testing and optimizing the energy flow of pure electric light trucks on actual roads has been developed.
