Abstract

The invention provides a current correction method and device, electronic equipment and a storage medium, and the method is applied to a motor controller equipped with a current sensor, and comprises the steps: obtaining a plurality of first current values and a plurality of corresponding second current values; the first current values are current values input into a motor controller, the second current values are current values collected by a current sensor, and each first current value corresponds to one second current value; and according to the plurality of first current values and the corresponding second current values, determining a current correction coefficient for correcting the second current values, so that the second current values approach to the first current values. In other words, after the current sensor and the motor controller are successfully assembled, a more accurate current correction coefficient can be determined through a plurality of first current values and a plurality of corresponding second current values, so that the second current values collected by the current sensor are closer to the first current values in an actual input circuit; and the current sampling precision is improved to a certain extent.
