The invention discloses a battery self-heating control method, a controller, a vehicle and a storage medium. The control method comprises the steps that the first temperature of a battery is obtained; determining a minimum alternating current frequency and a maximum alternating current amplitude corresponding to the first temperature; and controlling an alternating current power supply to output alternating current to the battery according to the minimum alternating current frequency and the maximum alternating current amplitude, so that the battery is self-heated. The minimum alternating current frequency and the maximum alternating current amplitude corresponding to the first temperature are determined by acquiring the first temperature, and the alternating current is output to the battery, so that self-heating of the battery is realized, energy loss of an external power device is reduced, influences on electromagnetic compatibility, noise, vibration and sound vibration roughness of a whole vehicle are reduced, and the service life of the battery is prolonged. And the whole vehicle application of battery self-heating is facilitated. And in the self-heating process of the battery, the influence of self-heating on the safety and attenuation of the battery is reduced, and lossless self-heating is realized.
