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.

    本申请提供了一种电流修正方法、装置、电子设备及存储介质,所述方法应用于装配有电流传感器的电机控制器,包括:获取多个第一电流值和相对应的多个第二电流值;第一电流值为输入电机控制器的电流值,第二电流值为电流传感器采集的电流值,每一个第一电流值对应一个第二电流值;根据多个第一电流值和相对应的第二电流值,确定电流修正系数,用于校正所述第二电流值,使得所述第二电流值趋近于所述第一电流值。换言之,将电流传感器和电机控制器装配成功后,通过多个第一电流值和相对应的多个第二电流值,可以确定更加准确的电流修正系数,使得电流传感器采集的第二电流值更加趋近于实际输入电路中的第一电流值,在一定程度上提高了电流采样精度。
