Abstract

This paper focuses on the heating strategies for electric vehicle batteries in low-temperature environments, analyzing the energy consumption and efficiency characteristics of different heating methods. Through theoretical analysis, we will establish a mathematical model to compare the advantages and disadvantages of constant current heating, constant voltage heating, and phase change material heating. The empirical study designed an experimental scheme and collected data to verify the actual performance of each strategy. The experimental results show that different heating strategies exhibit significant differences under varying temperature conditions, with bottlenecks in energy loss and efficiency. This study proposes optimization recommendations aimed at improving battery performance and vehicle energy efficiency. The conclusion points out that future research can further explore intelligent control and material improvements to enhance heating efficiency.
