The invention discloses an electric vehicle torque safety monitoring method and device and a storage medium, and relates to the technical field of torque monitoring. The current longitudinal acceleration value, the preset longitudinal acceleration value, the current consumed electric power of the motor and the preset consumed electric power of the motor of the electric vehicle are obtained according to the driving data; determining acceleration monitoring information according to the current longitudinal acceleration value and a preset longitudinal acceleration value; determining power monitoring information according to the current consumed electric power of the motor and the preset consumed electric power of the motor; the torque safety monitoring result of the electric automobile is determined through the acceleration monitoring information and the power monitoring information, the accurate motor torque is obtained through real-time calculation of the motor consumption power angle and the actual acceleration angle of the whole automobile, then torque safety monitoring is carried out, and on the premise that the hardware cost is not increased, the reliability of the electric automobile is improved. The torque safety monitoring of the electric vehicle can be effectively carried out, and the problem of unexpected acceleration or deceleration caused by abnormal output torque of the motor is avoided.
