Abstract：Taking the power battery system of an electric vehicle as the research object， the heat production rate of the battery cell is calculated based on the Bernardi battery heat production model， and the battery system simulation model is jointly established by MATLAB/Simulink and AMESim software. To improve the simulation accuracy， based on the test data， the model is checked， and the temperature change， SOC change and charging and discharging time of the battery under different working conditions are predicted on the basis of the calibrated model to verify the effect of the thermal management system of the power battery pack and the rationality of the control strategy.
