Battery control method of extended-range electric vehicle, storage medium and vehicle

The invention discloses a battery control method of an extended-range electric vehicle, a storage medium and a vehicle. The method comprises the steps that the vehicle is controlled to enter a pure electric mode or an extended-range mode; the vehicle control unit calculates a driver demand torque T according to the electric vehicle information, and the motor controller judges whether the vehicle is in a driving state or an energy recovery state according to the demand torque T; through mutual cooperation of the range extender, the lithium ion battery, the super-capacitor battery, the motor controller, the whole machine controller, the first high-voltage relay, the second high-voltage relay and the third high-voltage relay, under the working conditions of low temperature, low residual electric quantity and the like, when the motor outputs power, the super-capacitor is adopted for discharging or the range extender is combined for discharging, and the working efficiency is improved. The large attenuation of the
