The invention provides a battery temperature control method and a vehicle, the battery temperature control method is used for a thermal management system of the vehicle, and the thermal management system comprises a refrigerant loop, a cooling liquid loop and a switching valve. The refrigerant circuit includes a condenser, a compressor, and a first heat exchanger in series. The first heat exchanger is connected between the air outlet of the compressor and the condenser. The first sub-coolant loop comprises a battery, the second sub-coolant loop comprises a heater, and the third sub-coolant loop passes through the first heat exchanger. And the switching valve is connected among the first sub cooling liquid loop, the second sub cooling liquid loop and the third sub cooling liquid loop. The control method includes acquiring a working mode of the vehicle; and according to the working mode of the vehicle, the switching valve is controlled to operate, so that the first sub cooling liquid loop is selectively connected with at least one of the second sub cooling liquid loop and the third sub cooling liquid loop. The heating efficiency is high.
