The invention provides a new energy automobile power control method and device, electronic equipment and a computer readable storage medium. The new energy automobile power control method comprises the following steps: acquiring battery available charging and discharging power of a battery management system; determining available charging and discharging power of the motor based on the available charging and discharging power of the battery; acquiring current efficiency and current rotating speed of the motor; calculating a current torque limit value of the motor based on the available charge-discharge power of the motor, the current efficiency of the motor and the current rotating speed of the motor; a motor torque limit value is obtained based on battery available charging and discharging power conversion; a final available torque limit of the electric machine is calculated based on the electric machine torque limit, the available torque limit of the electric machine itself, and the vehicle state. According to the embodiment of the invention, the torque request of the motor can be accurately controlled, the output power of the battery is prevented from exceeding the limit to the greatest extent, and the service life of the battery is prolonged.
