Abstract

For electric vehicles, the energy consumption of the battery thermal management system is one of the key factors affecting driving mileage. To reduce the consumption in the summer, an energy optimisation method for battery thermal management systems, in which the liquid-cooling mode and air cooling mode are directly considered actuators, is presented in this paper. First, the influence of the vehicle speed on the air-cooling efficiency is considered in the modelling process of the battery thermal management system. Second, the weighted sum of the energy consumption and temperature tracking error of thermal management system is considered as the optimisation objective function. Third, the high dimensional dynamic programming (DP) algorithm is used to solve the nonlinear optimisation problem to obtain the optimal control trajectory. Finally, the effectiveness is verified under different driving conditions.
