Abstract

In this paper, a control-oriented electrothermal coupling battery liquid cooling thermal management model is presented, which includes the refrigeration cycle of the air-conditioning system, the cooling cycle of the battery system, and the battery electric-thermal coupled loop in electric vehicles. A cool-down mode is considered for the battery thermal management system in the hot summer. A high-fidelity physical-based model is established in Simcenter AMESim to validate the effectiveness of the proposed control-oriented model. The simulation results show that the deviations of the vehicle speed, battery state of charge, and temperature between the AMESim and proposed model are within 0.84km/h, 0.13%, and 0.23$^{circ}rm C$, respectively. Besides, the validation results show the same trend of the proposed dynamic character as AMESim, which indicates the proposed model is well suited for controller design in the future.
