This paper proposes a fuzzy PID control strategy with start-stop function for the direct battery cooling systems of electric vehicle. A whole vehicle model is developed using AMESim and Simulink co-simulation, to simulate the battery heat dissipation process under different control strategies. The results indicate that compared with traditional PID control, the start-stop fuzzy PID control has advantages including faster response time, shorter overshoot duration and lower system power consumption. Furthermore, the effect of shortened overshoot duration and power consumption savings is more pronounced in scenarios with higher ambient temperatures or lower driving speeds.
