Current sensor fault detection method and device, electronic equipment and storage medium

The invention discloses a current sensor fault detection method and device, electronic equipment and a storage medium, and the method comprises the steps: collecting motor operation electrical parameters of a to-be-detected motor when the to-be-detected motor operates normally; on the basis of the motor operation electrical parameters, characteristic electrical parameters of the to-be-detected motor are calculated, and the characteristic electrical parameters are used for representing current properties and/or voltage properties of the to-be-detected motor; and judging whether each phase current sensor in the to-be-detected motor has a sensor fault or not according to the characteristic electrical parameters of the to-be-detected motor. According to the invention, the current sensor fault detection is carried out according to the matching relation between the characteristic parameters obtained by calculating the motor operation electrical parameters during the operation of the to-be-detected motor and the pre
