Abstract
A method for controlling a temperature of a battery using a vehicle thermal management system including an HVAC subsystem including a refrigerant loop through which a refrigerant circulates, a battery cooling subsystem including a battery coolant loop through which a battery-side coolant circulates, and a battery chiller transferring heat between the refrigerant circulating in the refrigerant loop and the battery-side coolant circulating in the battery coolant loop may include: measuring a battery temperature and SOC value of the battery when charging the battery; determining a target temperature optimized for charging of the battery based on the measured battery temperature and SOC; and adjusting a temperature of the battery-side coolant by controlling at least one of the HVAC subsystem and the battery cooling subsystem according to whether the HVAC subsystem operates, a result of comparing an ambient temperature and the battery temperature, and a result of comparing the battery temperature and the target temperature.
