Low temperatures significantly impede electric vehicle battery performance, resulting in reduction in capacity2), charging speed, and efficiency. Currently, our company’s battery thermal management systems often rely on a static target heating temperature, ignoring the intricate relationship between battery temperature, ambient conditions, and charging power. To optimize thermal management, this paper proposes a virtual optimization methodology using Design of Experiments (DoE). Approach in this paper involves five key steps: 1) Factor Evaluation using a virtual battery model to assess the individual impact of various factors on charging time; 2) Experimental Design to determine the optimal number of experiments and select a suitable algorithm to build a metamodel; 3) Metamodel Development to build a predictive model based on virtual experiments; 4) Virtual Optimization to evaluate the effectiveness of different heating strategies in minimizing charging time; and 5) Real-World Validation to confirm the findings of virtual optimization through real-world vehicle experiments. By considering multiple factors and employing a more adaptive heating strategy, this research aims to significantly enhance user experience and reduce the environmental impact of electric vehicle charging, particularly in cold weather conditions. Findings from this paper demonstrate a significant reduction in charging time and an increase in charging efficiency compared to existing methods.
