摘要：

Power battery is the main power source of plug-in hybrid electric vehicles (PHEV), and the temperature change directly affects its safety and service life. Firstly, the temperature effect on the characteristics of batteries is analyzed, which reveals that the internal resistance of batteries varies greatly at different temperatures. On the basis, the thermal model of batteries is constructed. Furthermore, the energy management strategy based on model predictive control (MPC) is designed, and dynamic programming is used as receding horizon optimization. After that, three methods are used to restrict the temperature on the basis of MPC. Finally, the engine torque is obtained considering both fuel economy and battery temperature.
