A battery self-heating system, an electrical device, and a vehicle are disclosed. The system includes a first battery, a second battery, a converter, a motor, and first and second switch devices. The first and second batteries are connected via the first switch device, and their negative electrodes are connected to a first terminal of the converter. The second switch device is positioned between the negative electrode of the first battery and the converter. One positive electrode is connected to the motor, and the other to a second terminal of the converter. By controlling the motor and converter, the batteries alternately charge and discharge, generating an oscillating current for self-heating. This improves heating efficiency without the need for external heating devices, reducing system cost.
