As the electrification of transportation continues to gain momentum, the thermal management of onboard batteries remains a critical aspect to ensure optimal performance, efficiency, and longevity. To address this challenge, a standalone cooling system with a cooling capacity has been developed, specifically tailored for electric buses. This paper presents a comprehensive analysis of the performance comparison between simulation and testing data for a standalone battery cooling system designed for electric bus applications.
The study encompasses two primary components: numerical simulation using MATLAB Simulink and experimental testing. In the experimental phase, rigorous tests were conducted in a laboratory environment to evaluate the system's cooling performance under various operating conditions. Key metrics such as cooling capacity, temperature profile, and power consumption were measured and recorded to assess the system's effectiveness. A detailed numerical simulation model was developed using MATLAB to simulate the thermal dynamics of the standalone battery cooling system. The simulation model was validated by comparing its results with the actual test data obtained from the experimental testing phase. Through this comparative analysis, the accuracy and reliability of the simulation model were assessed, and its ability to predict the system's performance was evaluated.
The results of the study indicate a high degree of correlation between the simulation and testing data, demonstrating the effectiveness of the simulation model in accurately capturing the thermal behavior of the standalone battery cooling system. The close agreement between the simulated and experimental results validates the accuracy of the simulation model and underscores its utility as a predictive tool for system design and optimization. This paper contributes to advancing the understanding of thermal management systems for electric buses and provides valuable insights into the integration of experimental testing and numerical simulation in the design and evaluation process. The findings facilitate the development of more efficient and reliable battery cooling solutions, thereby enhancing the performance and sustainability of electric bus fleets.
