The invention discloses a torque distribution method and device for a pure electric vehicle and a storage medium, and belongs to the technical field of electric vehicles. The method comprises the steps of acquiring driving information and whole vehicle state information of the electric vehicle; determining a target torque currently required by the electric vehicle according to the driving information and the whole vehicle state information; and distributing the target torque to a first motor and a second motor of the electric vehicle according to a torque distribution requirement. According tothe invention, the target torque is obtained according to the current driving information of the electric vehicle and the state information of the whole vehicle, so that the target torque is ensuredto be optimally matched with the torque currently required by the electric vehicle, the waste of the torque provided by the electric vehicle is avoided, and the working efficiency of the motor and thestability of the dynamic property of the electric vehicle are improved.
