A thermal management system (100, Fig. 1) of an electric vehicle 200 receives an indication (502, Fig. 5) that a traction battery 204 is to be charged and obtains information (504, Fig. 5) representing an amount of thermal energy to be transferred between the battery and the thermal management system to obtain a target battery temperature. A plurality of operating modes of the thermal management system which satisfy the thermal energy transfer requirement is defined (506, Fig. 5) and an energy cost for each operating mode is determined (508, Fig. 5) using a model of the thermal management system. An operating mode having a lowest energy cost is selected (510, Fig. 5), and an output indicating the selected operating mode provided (512, Fig. 5). An operating mode may allow the transfer of thermal energy between a component of the vehicle and the traction battery. A future operating profile of the vehicle based on information of a predicted route to arrive at a charging station may be used to determine the energy cost of each operating mode. A control system, computer readable instructions, and a vehicle are also claimed.
