| description | The invention discloses an electric vehicle battery heating method, electronic equipment and a storage medium. The electric vehicle battery heating method comprises the steps: in response to a battery heating request, controlling a power module of an electric driving system to be electrically connected with a battery system, the battery system comprising one or more lithium batteries; controlling the power module to output oscillation current with an analog oscillation waveform; and controlling the electric driving system to stop outputting the oscillating current to the battery system in response to the battery heating stopping request. According to the invention, the electric driving system of the electric vehicle is utilized to generate the oscillation current required for spontaneous heating of the battery system, ohmic heat is generated through the internal resistance of the battery system, and the battery system is heated from the inside. The battery heating method is low in energy loss, more uniform in |
