The invention provides a battery heating method and device, a vehicle and a computer readable storage medium, and relates to the technical field of vehicles, and the method is applied to a battery heating system of the vehicle. The method comprises the steps that when it is detected that the environment temperature of a vehicle is lower than a preset temperature, motor torque output by a driving motor is controlled to be smaller than a torque threshold value; obtaining a target switching frequency; controlling the first switch module to be intermittently conducted according to the target switch frequency; wherein under the condition that the first switch module is switched on every time, the heating assembly, the first switch module and any two phases of windings in the three-phase windings form a loop, and a high-frequency pulse current is generated on a connecting line of the first switch module and the heating assembly. According to the battery heating system, the high-frequency pulse current can be applied to the heating assembly, so that uniform heating of the power battery is realized, the battery heating system can realize charging and discharging in a low-temperature environment, and the use reliability of the battery heating system is improved.
