A battery thermal management system (BTMS) for an electric vehicle and a hybrid electric vehicle is provided. The BTMS includes a refrigerant circuit having an evaporator, a chiller, one or more condensers, a compressor, an ejector, a primary directional control valve (DCV), a secondary DCV, an ejector DCV, a compressor input and output DCVs, a reference DCV, throttling valves, and controller to cool or heat the battery and passenger cabin. A coolant circuit having the battery, battery cooler, a battery output DCV, and a battery input DCV is communicated with the refrigerant circuit via the chiller. The battery input and output DCVs are coupled to the battery cooler and coupled to each other to isolate the refrigerant circuit. The controller controls the DCVs based on an optimal battery temperature range, coolant temperature, ambient temperature, passenger cabin temperature, and optimal passenger cabin temperature range.
