The invention provides a motor rotor angle deviation estimation method and system, electronic equipment, a readable storage medium and an electric vehicle. The method comprises the steps of obtaining measurement angles and observation angles of a motor rotor under multiple working points; for each working point, calculating the observation angle deviation of the motor rotor under the working point according to the measurement angle and the observation angle of the motor rotor under the working point; according to the observation angle deviation of the motor rotor under the multiple working points and a pre-established rotor angle deviation compensation model, the actual angle deviation of the motor rotor is obtained, the rotor angle deviation compensation model is used for representing the relation between the observation angle deviation and the actual angle deviation as well as the angle deviation error caused by the motor parameter deviation. According to the invention, the problem of inaccurate angle observation result caused by motor parameter deviation can be effectively compensated, and the angle deviation of the motor rotor can be accurately estimated.
