Abstract
Battery electric vehicle has become an important development direction of new energy vehicles because of its advantages of high efficiency, clean and low energy consumption. Thermal management system is required to ensure that the temperature of the battery and motor is in an efficient operating temperature range. However, as the energy required for cooling and heating of the thermal management system is provided by the power battery, the range of electric vehicles is severely reduced. In order to reduce the energy consumption of thermal management system, electric vehicle integrated thermal management system has become an important research direction. In this paper, an integrated thermal management system is designed for battery electric vehicle. The cooling and heating of battery, cooling of motor, and waste heat utilization are considered comprehensively. The simulation model of integrated thermal management system is established, and the accuracy of the model is verified by experiments. The cooling performance, heating performance and waste heat utilization performance of integrated thermal management system were analyzed under different boundary conditions.
