Research on control strategy of electric vehicle battery thermal management system based on MPC.

To reduce the battery performance attenuation of electric vehicles under high and low temperature conditions, it is necessary to design a battery thermal management system to avoid unnecessary energy consumption, while improving safety and endurance. In this paper, a battery thermal management system is established. Considering the time-delay and nonlinear characteristics of the battery system itself, the control strategy is designed based on multivariate model predictive control (MPC), and the simulation is carried out based on MATLAB. Simulation results show that MPC controller can save energy and improve efficiency, and have a better control effect than PID control. [ABSTRACT FROM AUTHOR]
